Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to an array substrate and a display panel. Background Technology

[0002] Organic Light Emitting Display (OLED) panels and other flat panel displays utilizing Light Emitting Diode (LED) devices are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, laptops, and desktop computers due to their advantages such as high image quality, energy saving, thin body, and wide application range, becoming the mainstream in display devices. In the traditional display panel manufacturing process, a fine metal mask (FMM) is typically used to pattern the light-emitting pixels. FMM technology is mature and has extensive mass production experience. However, FMM technology also has limitations such as limited precision, high development costs, and long development cycles. Fine metal maskless technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance aspects, offering advantages such as high performance, full-size display, and agile delivery.

[0108] In some embodiments, the orthographic projection of the first non-constant signal line corresponding to the second electrode onto the substrate and the orthographic projection of the second constant signal line overlapping with the orthographic projection of the second electrode onto the substrate are symmetrically arranged along the centerline of the first direction with respect to the orthographic projection of the second electrode onto the substrate.

[0109] In some embodiments, the distance between the orthographic projection of the first non-constant signal line corresponding to the second electrode onto the substrate and the centerline of the orthographic projection of the second electrode onto the substrate along the first direction is equal to the distance between the orthographic projection of the second constant signal line onto the substrate and the centerline of the orthographic projection of the second electrode onto the substrate along the first direction, which overlaps with the orthographic projection of the second electrode onto the substrate.

[0112] In some embodiments, the light-emitting units corresponding to the first electrode, the second electrode, and the third electrode form pixel units, and the arrangement of the constant signal lines and non-constant signal lines corresponding to the pixel units is the same as the arrangement of the pixel units.

[0113] In some embodiments, the pixel electrode includes a first electrode, a second electrode, and a third electrode, which are respectively disposed corresponding to light-emitting units of different colors.

Along the direction in which the isolation opening and the first opening are arranged side by side, the orthographic projection of the pixel electrode on the substrate exceeds the orthographic projection of the isolation structure on the substrate and overlaps with the orthographic projection of the outline of the first opening on the substrate.

[0124] This application provides an array substrate and a display panel. Since constant signal lines typically have a stable voltage level, they can act as shielding lines. By increasing the overlap area between constant signal lines and pixel electrodes, constant signal lines can effectively shield the electric field between pixel electrodes and non-constant signal lines, reduce the influence of parasitic capacitive coupling between non-constant signal lines and pixel electrodes, reduce the possibility of crosstalk between anode and non-constant signal lines, improve the reliability of the array substrate, and thus improve the reliability of the display panel.

[0148] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0149] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0150] In the array substrate, various circuits are arranged to drive the display panel's display and other functions. Within the array substrate's circuitry, parasitic capacitance exists between different conductive layers. When two conductive layers are adjacent, a capacitor is formed between them. If the voltage of one conductive layer changes, it will affect the voltage of the other conductive layer through capacitive coupling. For example, in the array substrate, there are electrodes used to drive light emission and non-constant signal lines beneath them. When the electrodes and non-constant signal lines overlap, the non-constant signal lines will change their output voltage or current over time based on control requirements. This causes the voltage of the electrodes during normal operation to be affected by the non-constant signal lines, resulting in capacitive coupling crosstalk, which in turn causes display panel malfunctions.

[0151] Figure 1 This is a cross-sectional structural diagram of an array substrate provided in an embodiment of this application. Figure 2 This is a partially enlarged structural schematic diagram of an array substrate provided in an embodiment of this application. Figure 3 This is a partially enlarged structural diagram of the first electrode layer in an array substrate provided in an embodiment of this application. Figure 4 This is a partially enlarged structural diagram of a signal line layer group in an array substrate provided in an embodiment of this application.

[0152] In view of this, firstly, please refer to Figures 1 to 4 This application provides an array substrate 100, which includes a substrate 10, a signal line layer group 20, and a first electrode layer 30. The signal line layer group 20 is located on one side of the substrate 10 and includes non-constant signal lines 21 and constant signal lines 22. The first electrode layer 30 is located on the side of the signal line layer group 20 facing away from the substrate 10 and includes a plurality of pixel electrodes 31. The overlapping area of ​​the non-constant signal lines 21 and pixel electrodes 31 projected onto the substrate 10 is smaller than the overlapping area of ​​the constant signal lines 22 and the same pixel electrode 31 projected onto the substrate 10.

[0153] In some embodiments, the substrate 10 primarily serves a supporting and load-bearing function, with other film layers sequentially stacked on the substrate 10. This stacking arrangement refers to the sequential stacking of other film layers along the thickness direction Z of the substrate 10. The substrate 10 may include one or more film layer structures, and the specific composition of the film layer structure of the substrate 10 is not limited in this embodiment. Furthermore, the thickness direction Z of other film layers located on one side of the substrate 10 is generally consistent with the thickness direction Z of the substrate 10 itself. Therefore, for ease of description, the thickness direction Z of the substrate 10 or other film layers mentioned later in this embodiment will be indicated using the same direction. The substrate 10 may be a rigid substrate 10, such as a glass substrate 10. Alternatively, the substrate 10 may be a flexible substrate 10, such as an organic material including polyimide.

[0154] The signal line layer group 20 may include one or more layers. For example, when the signal line layer group 20 includes multiple layers, the multiple signal line layer groups 20 are stacked sequentially in a direction away from the substrate 10. Optionally, the non-constant signal line 21 and the constant signal line 22 may be located in the same layer or in different layers. Of course, when the signal line layer group 20 is multi-layered, each layer may contain both constant signal lines 22 and non-constant signal lines 21, or it may contain only non-constant signal lines 21 or only constant signal lines 22.

[0155] Non-constant signal lines 21 refer to wires in the array substrate 100 that transmit signals of voltage or current that change over time. These signals are typically used to control various functions of the display panel. Optionally, the number of non-constant signal lines 21 may include one or more. The types of non-constant signal lines 21 may include one or more, for example, non-constant signal lines 21 may include data lines for transmitting pixel data, scan lines for controlling the on / off states of pixels, power lines for transmitting power supply voltage for dynamic voltage regulation, clock signal lines for transmitting clock signals, and so on.

[0156] A constant signal line 22 refers to a wire that transmits a signal with a constant voltage or current in the array substrate 100. These signals are typically used to provide a stable reference voltage or current to ensure that various parts of the display panel can function properly. Optionally, the number of constant signal lines 22 may include one or more. The types of constant signal lines 22 may include one or more, for example, constant signal lines 22 may include a reference voltage line for providing a stable reference voltage, a ground line for providing a stable ground potential, a power line for transmitting a stable power supply voltage, etc. Optionally, the power line may include a first power line for transmitting a power supply voltage to the anode and a second power line for transmitting a power supply voltage to the cathode.

[0157] The first electrode layer 30 is located on the side of the signal line layer group 20 facing away from the substrate 10. The first electrode layer 30 includes a plurality of pixel electrodes 31, which are spaced apart. Optionally, the plurality of pixel electrodes 31 can be arranged one-to-one with the light-emitting units 70 in the display panel. Optionally, the pixel electrode 31 can be an anode or a cathode.

[0158] In some embodiments, the non-constant signal line 21 and the constant signal line 22 can be wires extending in a single direction on the array substrate 100, and the orthographic projection of a non-constant signal line 21 onto the substrate 10 can overlap with the orthographic projections of multiple pixel electrodes 31 onto the substrate 10. Similarly, the orthographic projection of a constant signal line 22 onto the substrate 10 can overlap with the orthographic projections of multiple pixel electrodes 31 onto the substrate 10.

[0159] Optionally, the orthographic projection of a pixel electrode 31 onto the substrate 10 may overlap with the orthographic projection of one or more non-constant signal lines 21 onto the substrate 10.

[0160] Optionally, the orthographic projection of a pixel electrode 31 onto the substrate 10 may overlap with the orthographic projection of one or more constant signal lines 22 onto the substrate 10.

[0161] When the orthographic projection of a pixel electrode 31 onto the substrate 10 overlaps with the orthographic projection of a non-constant signal line 21 onto the substrate 10, the area of ​​the overlapping region of the orthographic projection of the pixel electrode 31 onto the substrate 10 and the orthographic projection of the non-constant signal line 21 onto the substrate 10 is also the overlapping area of ​​the orthographic projection of the non-constant signal line 21 onto the pixel electrode 31 onto the substrate 10. When the orthographic projection of a pixel electrode 31 onto the substrate 10 overlaps with the orthographic projections of multiple non-constant signal lines 21 onto the substrate 10, the sum of the areas of the overlapping regions of the orthographic projection of the pixel electrode 31 onto the substrate 10 and the orthographic projections of multiple non-constant signal lines 21 onto the substrate 10 is also the overlapping area of ​​the orthographic projection of the non-constant signal line 21 onto the pixel electrode 31 onto the substrate 10.

[0162] When the orthographic projection of a pixel electrode 31 on the substrate 10 overlaps with the orthographic projection of a constant signal line 22 on the substrate 10, the area of ​​the overlapping region of the orthographic projection of the pixel electrode 31 on the substrate 10 and the orthographic projection of the constant signal line 22 on the substrate 10 is also the overlapping area of ​​the orthographic projection of the constant signal line 22 and the pixel electrode 31 on the substrate 10. When the orthographic projection of a pixel electrode 31 on the substrate 10 overlaps with the orthographic projections of multiple constant signal lines 22 on the substrate 10, the sum of the areas of the overlapping regions of the orthographic projection of the pixel electrode 31 on the substrate 10 and the orthographic projections of multiple constant signal lines 22 on the substrate 10 is also the overlapping area of ​​the orthographic projection of the constant signal line 22 and the pixel electrode 31 on the substrate 10.

[0163] The overlapping area of ​​the orthographic projection of the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 can refer to the overlapping area of ​​the orthographic projection of one pixel electrode 31 on the substrate 10 and the orthographic projection of the non-constant signal line 21 on the substrate 10, or it can refer to the overlapping area of ​​the orthographic projection of all pixel electrodes 31 on the substrate 10 and the orthographic projection of the non-constant signal on the substrate 10.

[0164] The overlapping area of ​​the orthographic projection of the constant signal line 22 and the pixel electrode 31 on the substrate 10 can refer to the overlapping area of ​​the orthographic projection of one pixel electrode 31 on the substrate 10 and the orthographic projection of the constant signal line 22 on the substrate 10, or it can refer to the overlapping area of ​​the orthographic projection of all pixel electrodes 31 on the substrate 10 and the orthographic projection of the constant signal on the substrate 10.

[0165] It is understandable that when the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 refers to the overlapping area of ​​the orthogonal projection of a pixel electrode 31 on the substrate 10 and the orthogonal projection of the non-constant signal line 21 on the substrate 10, and the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 refers to the overlapping area of ​​the orthogonal projection of a pixel electrode 31 on the substrate 10 and the orthogonal projection of the constant signal line 22 on the substrate 10, the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 being smaller than the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 means that for the same pixel electrode 31, the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 is smaller than the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10.

[0166] This application provides an array substrate 100. By making the projected area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 smaller than the overlapping area of ​​the projected area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10, the capacitive coupling between the non-constant signal line 21 and the pixel electrode 31 is reduced. This reduces the impact of voltage or current changes in the non-constant signal line 21 on the voltage in the pixel electrode 31 through the coupling effect, thus reducing the possibility of voltage changes in the pixel electrode 31. The capacitive coupling between the constant signal line 22 and the pixel electrode 31 is increased, thereby increasing the impact of the stable voltage in the constant signal line 22 on the voltage in the pixel electrode 31. This further reduces the possibility of voltage changes in the pixel electrode 31, lowers the possibility of crosstalk between the pixel electrode 31 and the non-constant signal line 21, improves the reliability of the array substrate 100, and ultimately improves the reliability of the display panel.

[0167] In some alternative embodiments, the ratio of the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 to the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 is S1, where S1 ≤ 40%.

[0168] The overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 and the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 can be understood as the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 and the projected area of ​​the pixel electrode 31 on the substrate 10 for the same pixel electrode 31.

[0169] For example, the ratio of the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 to the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 is 1%, 2%, 3%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, or 40%.

[0170] The embodiments of this application, through the above-described settings, help to reduce the overlap area between the non-constant signal line 21 and the pixel electrode 31, thereby reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31.

[0171] Optionally, the ratio of the overlapping area of ​​the non-constant signal line 21 and the pixel electrode 31 on the substrate 10 to the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 is 5%-35%. This setting can reduce the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, while also helping to reduce the internal resistance of the non-constant signal line 21 and improve the response speed of the array substrate 100.

[0172] In some alternative embodiments, the ratio of the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 to the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 is S2, where S2 ≥ 45%.

[0173] The overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 and the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 can be understood as the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 and the projected area of ​​the pixel electrode 31 on the substrate 10 for the same pixel electrode 31.

[0174] For example, the ratio of the overlapping area of ​​the constant signal line 22 and the pixel electrode 31 on the substrate 10 to the corresponding projected area of ​​the pixel electrode 31 on the substrate 10 is 45%, 46%, 48%, 50%, 60%, 70%, 80%, 90%, or 100%.

[0175] The embodiments of this application, through the above-described configuration, facilitate the increase of the overlap area between the constant signal line 22 and the pixel electrode 31, thereby enhancing the capacitive coupling effect between the constant signal line 22 and the pixel electrode 31, reducing the possibility of abnormal voltage in the pixel electrode 31, improving the reliability of the array substrate 100, and further improving the reliability of the display panel.

[0176] In some alternative embodiments, such as Figure 3 As shown, the pixel electrode 31 includes a first electrode 311, a second electrode 312, and a third electrode 313, which are respectively disposed corresponding to light-emitting units 70 of different colors.

[0177] This application embodiment does not limit the color of the light-emitting unit 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313. Exemplarily, the light-emitting unit 70 includes different colors; for example, the light-emitting unit 70 includes a red light-emitting unit 70, a green light-emitting unit 70, and a blue light-emitting unit 70. Optionally, the first electrode 311 may correspond to the red light-emitting unit 70, the second electrode 312 may correspond to the blue light-emitting unit 70, and the third electrode 313 may correspond to the green light-emitting unit 70. Optionally, the light-emitting unit 70 may also include a white light-emitting unit 70, and one of the first electrode 311, the second electrode 312, and the third electrode 313 may also correspond to the white light-emitting unit 70.

[0178] The embodiments of this application do not limit the shape and size of the first electrode 311, the second electrode 312, and the third electrode 313. Exemplarily, the first electrode 311, the second electrode 312, and the third electrode 313 may have the same shape, or they may have different shapes, or two of them may be the same, or all three may be different.

[0179] The embodiments of this application, through the above-described settings, help to reduce the possibility of crosstalk between the pixel electrodes 31 corresponding to different color light-emitting units 70 and the non-constant signal lines 21, improve the stability of the display effect of different color light-emitting units 70, and thus improve the reliability of the display panel.

[0180] In some alternative embodiments, such as Figures 1 to 4 As shown, the centroids of a first electrode 311, a second electrode 312, and two third electrodes 313 are respectively arranged at the four vertices of the virtual quadrilateral Q.

[0181] In other words, the line connecting the centers of an adjacent first electrode 311, a second electrode 312, and two third electrodes 313 can form a virtual quadrilateral Q. In some embodiments, the first electrode 311 and the second electrode 312 can be arranged at two facing vertices of the virtual quadrilateral Q. The two third electrodes 313 can be arranged at two facing vertices of the virtual quadrilateral Q. The virtual quadrilateral Q can be a rectangle, a rhombus, a square, etc.

[0182] It is understandable that a first electrode 311, a second electrode 312, and two third electrodes 313 are respectively arranged at the four vertices of the virtual quadrilateral Q, and the corresponding color light-emitting unit 70 is also arranged at the four vertices of the virtual quadrilateral Q, thereby forming the sub-pixel arrangement structure in the display panel. Furthermore, through this sub-pixel arrangement structure, color rendering can be driven by sharing adjacent sub-pixels, and high resolution can be achieved with a small number of pixels.

[0183] In some embodiments, such as Figure 3 As shown, in the region corresponding to the virtual quadrilateral Q, two third electrodes 313 are spaced apart along the first direction X, and the first electrode 311 and the second electrode 312 are spaced apart along the second direction Y. The first direction X, the second direction Y, and the thickness direction Z of the array substrate 100 intersect each other. Optionally, the first direction X, the second direction Y, and the thickness direction Z of the array substrate 100 are perpendicular to each other.

[0184] Within a virtual quadrilateral Q, specifically for a virtual quadrilateral Q, two third electrodes 313 are spaced apart along a first direction X, and a first electrode 311 and a second electrode 312 are spaced apart along a second direction Y. At least a portion of the orthographic projection of the first electrode 311 onto the first plane and at least a portion of the orthographic projection of the second electrode 312 onto the first plane are located between the orthographic projections of the two third electrodes 313 onto the first plane. The first plane is perpendicular to the second direction Y. Optionally, the centroid of the first electrode 311 passes through a perpendicular line perpendicular to the midpoint of the line connecting the centroids of the two third electrodes 313. The centroid of the second electrode 312 passes through a perpendicular line perpendicular to the midpoint of the line connecting the centroids of the two third electrodes 313. Optionally, the line connecting the centroids of the first electrode 311 and the second electrode 312 can be parallel to or intersect the second direction Y.

[0185] In some alternative embodiments, such as Figures 2 to 4 As shown, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along a first direction X and are spaced apart along a second direction Y. Specifically, the orthographic projection of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10 overlaps at least with the orthographic projection of the first electrode 311 onto the substrate 10; the orthographic projection of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10 overlaps at least with the orthographic projection of the second electrode 312 onto the substrate; and the orthographic projection of the first non-constant signal line 211 onto the substrate 10 overlaps at least with the orthographic projections of the first electrode 311 and the second electrode 312 onto the substrate 10.

[0186] Optionally, the functions of the first constant signal line 221 and the second constant signal line 222 are different.

[0187] Optionally, the number of first constant signal lines 221 may include one or more.

[0188] Optionally, the number of second constant signal lines 222 may include one or more.

[0189] Optionally, the number of the first non-constant signal lines 211 may include one or more.

[0190] Optionally, the constant signal line 22 may also include a third constant signal line, a fourth constant signal line, or more.

[0191] Optionally, the non-constant signal line 21 may also include a second non-constant signal line, a third non-constant signal line, a fourth non-constant signal line, or more.

[0192] The embodiments of this application do not limit the arrangement of the first constant signal line 221, the second constant signal line 222, and the third constant signal line 22. For example, the first constant signal line 221, the second constant signal line 222, and the third constant signal line 22 can be arranged alternately along the second direction Y, or they can be arranged according to a predetermined arrangement rule according to actual design requirements.

[0193] In some embodiments, the orthographic projections of the first constant signal line 221 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projections of the first constant signal line 221 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the second electrode 312 on the substrate 10. In other embodiments, the orthographic projections of the second constant signal line 222 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projections of the second constant signal line 222 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the second electrode 312 on the substrate 10. In some other embodiments, the orthographic projections of the first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 onto the substrate 10 overlap with the orthographic projection of the first electrode 311 onto the substrate 10. Furthermore, the orthographic projections of the first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 onto the substrate 10 overlap with the orthographic projection of the second electrode 312 onto the substrate 10. In other embodiments, the orthographic projections of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10, and the orthographic projection of the first non-constant signal line 211 onto the substrate 10 may also at least partially overlap with the orthographic projection of the third electrode 313 onto the substrate 10.

[0194] The embodiments of this application, through the above-described settings, help to reduce the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, while increasing the flexibility of the arrangement of the constant signal line 22 and the non-constant signal line 21, and improving the applicability of the array substrate 100.

[0195] In some alternative embodiments, the orthographic projections of the first constant signal line 221 and the second constant signal line 222 on the substrate 10 overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projections of the first constant signal line 221 and the second constant signal line 222 on the substrate 10 overlap with the orthographic projection of the second electrode 312 on the substrate 10.

[0196] In some optional embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction; and / or, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction.

[0197] The second constant signal line 222 corresponding to the first electrode 311, where "corresponding" refers to the second constant signal line 222 used to drive the first electrode 311, and the portion of the second constant signal line 222 overlapping the orthographic projection of the first electrode 311 on the substrate 10. Similarly, the "correspondence" in the first constant signal line 221 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the first electrode 311, the first constant signal line 221 corresponding to the second electrode 312, the second constant signal line 222 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the second electrode 312, the first constant signal line 221 corresponding to the third electrode 313, the second constant signal line 222 corresponding to the third electrode 313, and the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222 corresponding to the first electrode 311, is consistent and will not be described again.

[0198] In some embodiments, such as Figure 4As shown, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction. Furthermore, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction. Optionally, the two first non-constant signal lines 211 and the two first constant signal lines 221 can be symmetrically arranged with respect to the second constant signal line 222. For example, the arrangement of the two first non-constant signal lines 211, the two first constant signal lines 221, and the second constant signal line 222 along the second direction Y can be, in sequence, the first constant signal line 221, the first non-constant signal line 211, the second constant signal line 222, the first non-constant signal line 211, and the first constant signal line 221; or it can be, the first non-constant signal line 211, the first constant signal line 221, the second constant signal line 222, the first constant signal line 221, and the first non-constant signal line 211. Of course, the two first non-constant signal lines 211 and the two first constant signal lines 221 can also be asymmetrically arranged with respect to the second constant signal line 222. For example, the arrangement could be: the first constant signal line 221, the first non-constant signal line 211, the second constant signal line 222, the first constant signal line 221, and the first non-constant signal line 211.

[0199] In some embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 has a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its width direction. In still other embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 has a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its width direction.

[0200] The width direction of the second constant signal line 222 can be a direction perpendicular to the extension direction of the second constant signal line 222.

[0201] In these alternative embodiments, by providing first constant signal lines 221 on both sides of the second constant signal line 222 along its width direction, it is beneficial to increase the overlap area between the constant signal line 22 and the pixel electrode 31, thereby reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31. By providing first non-constant signal lines 211 on both sides of the second constant signal line 222 along its width direction, it is beneficial to improve the design flexibility of the first non-constant signal lines 211 and increase the applicability of the array substrate 100.

[0202] In some embodiments, the orthographic projections of multiple first constant signal lines 221 and / or multiple first non-constant signal lines 211 on the substrate 10 of the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 on both sides of its own width direction are symmetrically arranged with the center line of the first direction X as the axis of symmetry of the orthographic projection of the first electrode 311 on the substrate 10.

[0203] For example, the number of first constant signal lines 221 includes two, and the number of first non-constant signal lines 211 includes two. The orthographic projections of the two first constant signal lines 221 onto the substrate 10 are symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry. The orthographic projections of the two first non-constant signal lines 211 onto the substrate 10 are also symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry. Alternatively, the orthographic projections of one first constant signal line 221 onto the substrate 10 and one first non-constant signal line 211 onto the substrate 10 are symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry.

[0204] In some embodiments, the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the orthographic projection of the first electrode 311 onto the substrate 10 or the orthographic projection of the second electrode 312 onto the substrate 10 along the center line of the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0205] It is understandable that the orthographic projections of the first segment 211a and the second segment 211b onto the substrate 10 are both located within the orthographic projections of the first electrode 311 or the second electrode 312 onto the substrate 10.

[0206] For example, the first non-constant signal line 211 corresponding to the first electrode 311 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. Alternatively, the first non-constant signal line 211 corresponding to the second electrode 312 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. Optionally, when the orthographic projections of the second segment 211b onto the substrate 10 and the orthographic projections of the adjacent second constant signal line 222 onto the substrate 10 are designed to be equally spaced, the minimum distance between the orthographic projections of the second segment 211b onto the substrate 10 and the adjacent second constant signal line 222 onto the substrate 10 is also the distance between the orthographic projections of the second segment 211b onto the substrate 10 and the adjacent second constant signal line 222 onto the substrate 10. The second segment 211b and its adjacent second constant signal line 222 can also be designed with unequal spacing.

[0207] Optionally, the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are parallel.

[0208] Optionally, the second segment 211b and the second constant signal line 222 projected onto the substrate 10 are parallel to each other.

[0209] In some embodiments, the extension direction of the orthographic projection of the second segment 211b onto the substrate 10 intersects the extension direction of the orthographic projection of the second constant signal line 222 onto the substrate 10, and along a direction away from the centroid of the first electrode 311 or the second electrode 312, the distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 gradually increases.

[0210] Optionally, the orthographic projection of the second segment 211b onto the substrate 10 can be a straight line inclined relative to the extension direction of the orthographic projection of the second constant signal line 222 onto the substrate 10. The second segment 211b may also include multiple sub-segments, and the distance between the orthographic projection of the multiple sub-segments onto the substrate 10 and the orthographic projection of the adjacent constant signal line 22 onto the substrate 10 gradually increases along the direction away from the centroid of the first electrode 311 or the second electrode 312.

[0211] In some alternative embodiments, the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0212] For example, the first non-constant signal line 211 corresponding to the first electrode 311 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. And / or, the first non-constant signal line 211 corresponding to the second electrode 312 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0213] In some alternative embodiments, the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are parallel.

[0214] In some alternative embodiments, the distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 gradually increases along a direction away from the centroid of the orthographic projection of the first electrode 311 onto the substrate 10 or the orthographic projection of the second electrode 312 onto the substrate 10.

[0215] For example, the distance between the third segment 211c and its adjacent second constant signal line 222 gradually increases from the centroid of the first electrode 311 towards its edge along the first direction X. And / or, the distance between the third segment 211c and its adjacent second constant signal line 222 gradually increases from the centroid of the second electrode 312 towards its edge along the first direction X. Here, "gradually increases" can be a step-like increase or a proportional increase. Through the above arrangement, a light-transmitting area can be formed between the second constant signal line 222 and the first non-constant signal line 211, thereby increasing the light transmittance of the display panel 200.

[0216] In some embodiments, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10.

[0217] For example, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10. And / or, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10. This arrangement helps to increase the flatness of the first electrode 311 and the second electrode 312, reducing the possibility of color shift in the light-emitting units 70 corresponding to the first electrode 311 and the second electrode 312 under different viewing angles.

[0218] In some embodiments, the first constant signal line 221 includes a power supply line. For example, the power supply line may be a first power supply line for transmitting a power supply voltage to the anode and a second power supply line for transmitting a power supply voltage to the cathode. The first constant signal line 221 is at least one of the first power supply line and the second power supply line.

[0219] In some embodiments, the second constant signal line 222 includes an initialization voltage line. For example, the initialization voltage line may be a first initialization voltage line for gate reset of the thin-film transistor 40 and a second initialization voltage line for anode reset. The second constant signal line 222 is at least one of the first initialization voltage line and the second initialization voltage line.

[0220] In some embodiments, the first non-constant signal line 211 includes a data line.

[0221] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, in the region corresponding to the virtual quadrilateral Q, a through hole K1 is provided on the first constant signal line 221, and the pattern formed by the orthographic projection of the pixel electrode 31 on the substrate 10 and the outline of the through hole K1 overlaps at least partially with the orthographic projection of the substrate 10.

[0222] Optionally, a closed via K1 structure is provided on the first constant signal line 221. Optionally, the via K1 can be circular, elliptical, rectangular, or other shapes.

[0223] Optionally, within a virtual quadrilateral Q, the number of through holes K1 can be one or more.

[0224] It is understood that within a virtual quadrilateral Q, a portion of the structures of the first electrode 311, the second electrode 312, and the third electrode 313 extend towards the center of the virtual quadrilateral Q to occupy a portion of the area within the virtual quadrilateral Q. The orthographic projection of the first electrode 311 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10. And / or, the orthographic projection of the second electrode 312 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10. And / or, the orthographic projection of the third electrode 313 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10. Taking the first electrode 311 as an example, "at least partially overlapping" here means that a part of the orthographic projection of the first electrode 311 on the substrate 10 overlaps with a part of the orthographic projection of the pattern enclosed by the outline of the through hole K1 on the substrate 10. Alternatively, the orthographic projection of the pattern enclosed by the outline of the through hole K1 on the substrate 10 may fall within the orthographic projection of the first electrode 311 on the substrate 10.

[0225] The via profile K1 refers to the edge of the via K1 structure on the first constant signal line 221.

[0226] Optionally, the through hole K1 can be located at the centroid of the virtual quadrilateral Q, or at any position of the virtual quadrilateral Q.

[0227] In these alternative embodiments, the above-described arrangement helps to increase the overlap area between the pixel electrode 31 and the first constant signal line 221, thereby enhancing the capacitive coupling effect between the pixel electrode 31 and the constant signal line 22, reducing the possibility of crosstalk between the pixel electrode 31 and the non-constant signal line 21, improving the reliability of the array substrate 100, and thus improving the reliability of the display panel.

[0228] In some alternative embodiments, such as Figures 1 to 4 As shown, in the region corresponding to the virtual quadrilateral Q, the first constant signal line 221 includes a surface signal portion 221a and a connecting portion 221b that are connected to each other. The dimension of the surface signal portion 221a along the second direction Y is larger than the dimension of the connecting portion 221b along the second direction Y. The surface signal portion 221a and the connecting portion 221b enclose a through hole K1. The orthographic projection of the third electrode 313 on the substrate 10 and the orthographic projection of the surface signal portion 221a on the substrate 10 are at least partially overlapped.

[0229] Optionally, the edge of the surface signal section 221a is at least partially located within the orthographic projection of the third electrode 313 onto the substrate 10.

[0230] Optionally, the edge of the surface signal section 221a includes a first side L1 extending along the first direction X, at least a portion of which is located within the orthographic projection of the third electrode onto the substrate 10.

[0231] Optionally, the orthographic projection of the first side L1 onto the substrate 10 is entirely within the orthographic projection of the third electrode onto the substrate 10.

[0232] Optionally, the first side L1 is a straight side.

[0233] Optionally, within a region corresponding to a virtual quadrilateral Q, the number of face signal units 221a may include one or more. When only one face signal unit 221a is provided within a region corresponding to a virtual quadrilateral Q, adjacent face signal units 221a within the same region are connected by a connecting part 221b. When multiple face signal units 221a are provided within a region corresponding to a virtual quadrilateral Q, the multiple face signal units 221a within the same region are connected by a connecting part 221b, and adjacent face signal units 221a within the same region are connected by a connecting part 221b. Here, "within the region corresponding to the virtual quadrilateral" refers to a region including a virtual quadrilateral and the face signal unit, connecting part, and other structures corresponding to that virtual quadrilateral.

[0234] The surface signal portion 221a and the connecting portion 221b enclose and form a through hole K1, and a portion of the edge of the surface signal portion 221a and a portion of the edge of the connecting portion 221b form the outline of the through hole K1.

[0235] Optionally, a portion of the orthographic projection of the third electrode 313 onto the substrate 10 overlaps with a portion of the orthographic projection of the surface signal portion 221a onto the substrate 10; or, the orthographic projection of the third electrode 313 onto the substrate 10 falls within the orthographic projection of the surface signal portion 221a onto the substrate 10; or, the orthographic projection of the surface signal portion 221a onto the substrate 10 falls within the orthographic projection of the third electrode 313 onto the substrate 10.

[0236] In some embodiments, in the region corresponding to the virtual quadrilateral Q, two third electrodes 313 are spaced apart along the first direction X. By making the size of the surface signal portion 221a along the second direction Y larger than the size of the connecting portion 221b along the second direction Y, the overlap area of ​​the surface signal portion 221a and the third electrode 313 on the substrate 10 is increased. At the same time, the size of the third electrode 313 in the first direction X is reduced, making the distance between the two third electrodes 313 along the first direction X smaller, thereby reducing the overall area of ​​the virtual quadrilateral Q, and further reducing the area of ​​the sub-pixels in the display panel, thereby improving the resolution of the display panel.

[0237] like Figure 4 As shown, in the region corresponding to the virtual quadrilateral Q, there are two surface signal units 221a. The two surface signal units 221a are respectively disposed on both sides of the through hole K1 along the first direction X, and the two surface signal units 221a are respectively disposed in a one-to-one correspondence with the two third electrodes 313.

[0238] Optionally, the two surface signal units 221a can be connected by one or more connecting units 221b.

[0239] Figure 5 This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application.

[0240] In some alternative embodiments, such as Figure 2 and Figure 5 As shown, in the region corresponding to the virtual quadrilateral Q, at least one of the first electrode 311 and the second electrode 312 is disposed in an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the connecting portion 221b on the substrate 10.

[0241] In some embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projections of the first electrode 311 onto the substrate 10 overlap with the orthographic projections of the connecting portion 221b onto the substrate 10, and the orthographic projections of the second electrode 312 onto the substrate 10 overlap with the orthographic projections of the connecting portion 221b onto the substrate 10. In other embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projections of the first electrode 311 onto the substrate 10 overlap with the orthographic projections of the connecting portion 221b onto the substrate 10. In still other embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projections of the second electrode 312 onto the substrate 10 overlap with the orthographic projections of the connecting portion 221b onto the substrate 10.

[0242] It is understandable that when the orthographic projections of the first electrode 311 and the second electrode 312 on the substrate 10 both overlap with the orthographic projections of the connecting portion 221b on the substrate 10, the orthographic projections of the first electrode 311 on the substrate 10 and the orthographic projections of the second electrode 312 on the substrate 10 overlap with the orthographic projections of different connecting portions 221b on the substrate 10, respectively.

[0243] The embodiments of this application, through the above-described configuration, facilitate an increase in the overlap area between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, thereby reducing the possibility of crosstalk between the first electrode 311 and / or the second electrode 312 and the non-constant signal line 21, and further reducing the possibility of display abnormalities in the light-emitting unit 70 corresponding to the first electrode 311 and / or the second electrode 312, thus improving the reliability of the display panel.

[0244] In the region corresponding to the virtual quadrilateral Q, there are two connecting portions 221b. The two connecting portions 221b are respectively disposed on both sides of the through hole K1 along the second direction Y. The orthographic projection of one of the connecting portions 221b on the substrate 10 overlaps at least partially with the orthographic projection of the first electrode 311 on the substrate 10. The orthographic projection of the other connecting portion 221b on the substrate 10 overlaps at least partially with the orthographic projection of the second electrode 312 on the substrate 10.

[0245] Optionally, both connecting portions 221b can be electrically connected to the surface signal portions 221a located on both sides of the through hole K1 along the first direction X. Alternatively, only one connecting portion 221b can be electrically connected to the surface signal portions 221a located on both sides of the through hole K1 along the first direction X, and the other connecting portion 221b can be electrically connected to only one of the two surface signal portions 221a located on both sides of the through hole K1 along the first direction X, or the other connecting portion 221b can be not electrically connected to the surface signal portion 221a. Of course, neither connecting portion 221b can be electrically connected to the surface signal portion 221a.

[0246] In these alternative embodiments, the above-described arrangement helps to further increase the overlap area between all pixel electrodes 31 and constant signal lines 22, thereby reducing the possibility of crosstalk between all pixel electrodes 31 and non-constant signal lines 21 and improving the overall display effect of the display panel.

[0247] In some alternative embodiments, such as Figures 2 to 5 As shown, in the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of at least one of the first electrode 311 and the second electrode 312 on the substrate 10 overlaps with the orthographic projection of the through hole K1 on the substrate 10.

[0248] Optionally, the connecting portion 221b may include a first connecting portion 221b1 and a second connecting portion 221b2, wherein the orthographic projection of the first electrode 311 on the substrate 10 at least partially overlaps with the orthographic projection of the first connecting portion 221b1 on the substrate 10, and the orthographic projection of the second electrode 312 on the substrate 10 at least partially overlaps with the orthographic projection of the second connecting portion 221b2 on the substrate 10.

[0249] In some embodiments, within the region corresponding to the virtual quadrilateral Q, a portion of the first electrode 311 extends along the second direction Y and toward the centroid of the through hole K1, such that the first electrode 311 includes a first region, a second region, and a third region. The orthographic projection of the first region onto the substrate 10 is located on the side of the orthographic projection of the first connection portion 221b1 onto the substrate 10 that is away from the outline of the through hole K1. The orthographic projection of the second region onto the substrate 10 overlaps with the orthographic projection of the first connection portion 221b1 onto the substrate 10. The orthographic projection of the third region onto the substrate 10 overlaps with the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10. Furthermore, the orthographic projection of a portion of the third region onto the substrate 10 is located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10. The overlap relationship between the second electrode 312 and the pattern enclosed by the outline of the through hole K1 is the same as that between the first electrode 311 and the pattern enclosed by the outline of the through hole K1, and will not be repeated in this embodiment.

[0250] In some embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projections of the first electrode 311 and the second electrode 312 onto the substrate 10 both exceed the orthographic projection of the connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10. In other embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the first electrode 311 onto the substrate 10 exceeds the orthographic projection of the first connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10. In still other embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the second electrode 312 onto the substrate 10 exceeds the orthographic projection of the second connecting portion 221b2 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10.

[0251] The embodiments of this application, through the above-described configuration, facilitate an increase in the overlap area between the first electrode 311 and / or the second electrode 312 and the connecting portion 221b, thereby increasing the overlap area between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, enhancing the capacitive coupling effect between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, reducing the possibility of crosstalk between the pixel electrode 31 and the non-constant signal line 21, and improving the reliability of the display panel.

[0252] Figure 6 This is a partially enlarged structural schematic diagram of the first electrode layer in another array substrate 100 provided in this application embodiment.

[0253] In some embodiments, such as Figure 5 and Figure 6 As shown, the edge of at least one of the first electrode 311 and the second electrode 312 includes a second side L2, and at least a portion of the second side L2 is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through hole K1 within the orthographic projection of the substrate 10. In some embodiments, the second side L2 extends along a first direction X.

[0254] When, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the first electrode 311 onto the substrate 10 exceeds the orthographic projection of the first connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10, at least a portion of the orthographic projection of the second side L2 onto the substrate 10 lies within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10. The overlap relationship between the second electrode 312 along the second direction Y, including the second side L2, and the pattern enclosed by the outline of the through hole K1 is the same as the overlap relationship between the first electrode 311 along the second direction Y, including the second side L2, and the pattern enclosed by the outline of the through hole K1, but it can also be different.

[0255] Optionally, the orthographic projection of the second side L2 onto the base 10 is entirely within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the base 10.

[0256] In some embodiments, the edges of both the first electrode 311 and the second electrode 312 include a second side L2, which extends along the first direction X. That is, the edges of both the first electrode 311 and the second electrode 312 along the second direction Y are both second sides L2. At least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10. In other embodiments, the edge of the first electrode 311 along the second direction Y is the second side L2, and at least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10. In still other embodiments, the edge of the second electrode 312 along the second direction Y is the second side L2, and at least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10.

[0257] In these alternative embodiments, by providing a second side L2, the area of ​​the first electrode 311 and the second electrode 312 blocking the through hole K1 in the thickness direction Z is reduced, so that the through hole can be used as a light-transmitting hole or a clearance hole for other conductive structures. This increases the overlap area between the first electrode 311 and the second electrode 312 and the constant signal line 22, while improving the design flexibility of the through hole K1.

[0258] In some other embodiments, the edge of the third electrode 313 includes a second side L2 that extends along the first direction X, that is, the edge of the third electrode 313 along the second direction Y is the second side L2, thereby reducing the size of the third electrode 313 in the second direction Y.

[0259] Optionally, the second side can be a straight edge.

[0260] In some alternative embodiments, such as Figures 1 to 4 As shown, the array substrate 100 also includes a thin-film transistor 40. The pixel electrode 31 is electrically connected to the thin-film transistor through an electrode connection portion 50. The number of electrode connections includes a plurality of them. At least a portion of the plurality of electrode connections is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the outline of the via K1 within the orthographic projection of the substrate.

[0261] Optionally, the thin-film transistor 40 includes a source, a drain, a gate, and a semiconductor. The source and drain are spaced apart and both are electrically connected to the semiconductor. Optionally, the source and drain can be located on the same side, the semiconductor is located between the source / drain layer and the substrate 10, the gate can be located between the semiconductor and the source / drain layer, or the gate can be located between the semiconductor and the substrate 10.

[0262] The pixel electrode 31 and the thin-film transistor 40 are electrically connected via the electrode connection portion 50, so that the thin-film transistor 40 can control and drive the pixel electrode 31. Optionally, the pixel electrode can be electrically connected to the source via the electrical connection portion 221b, and the pixel electrode 31 can also be electrically connected to the drain via the electrical connection portion 221b.

[0263] Optionally, the constant signal line 22 may be located between the source / drain layer and the first electrode layer 30.

[0264] Optionally, the non-constant signal line 21 may be located between the source / drain layer and the first electrode layer 30.

[0265] Optionally, the orthographic projections of the plurality of electrode connection portions 50 on the substrate 10 are all located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 on the substrate 10.

[0266] Optionally, the electrode connection portion 50 includes a plurality of electrode connection portions 50, and the orthographic projection of a portion of the plurality of electrode connection portions 50 onto the substrate 10 is entirely located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10.

[0267] When the constant signal line 22 can be located between the source / drain layer and the first electrode layer 30, the via K1 can be used as a clearance hole, so that the electrode connection portion 50 passes through the via K1 to electrically connect the thin film transistor 40 and the pixel electrode 31. This increases the area of ​​the constant signal line 22 while reducing the possibility of interference between the electrode connection portion 50 and the constant signal line 22, thereby improving the fabrication yield of the array substrate 100.

[0268] Figure 7 This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application.

[0269] In some alternative embodiments, such as Figure 1 and Figure 7 As shown, the electrode connection portion 50 includes a first electrode connection portion 51 and a second electrode connection portion 52. The first electrode 311 is electrically connected to the thin-film transistor 40 through the first electrode connection portion 51, and the second electrode 312 is electrically connected to the thin-film transistor 40 through the second electrode connection portion 52. The pattern formed by the outline of the through-hole K1 within the virtual quadrilateral Q in the orthographic projection of the first electrode 311 and the second electrode connection portion 52 adjacent to the first electrode in the orthographic projection of the second electrode 312 on the substrate 10 is within the orthographic projection of the substrate 10. The pattern formed by the outline of the through-hole K1 within the virtual quadrilateral adjacent to the virtual quadrilateral Q in the orthographic projection of the second electrode connection portion 52 on the substrate 10 is also within the orthographic projection of the second electrode connection portion 52 on the substrate 10.

[0270] For example, two adjacent virtual quadrilaterals Q along the second direction Y are successively a first virtual quadrilateral Q1 and a second virtual quadrilateral Q2, wherein the first virtual quadrilateral Q1 and the second virtual quadrilateral Q2 share a first electrode 311. Within the second virtual quadrilateral Q2, the orthographic projection of the first electrode connection portion 51 corresponding to the first electrode 311 onto the substrate 10 is located within the orthographic projection of the through hole K1 within the first virtual quadrilateral Q1. Similarly, the orthographic projection of the second electrode connection portion 52 corresponding to the second electrode 312 onto the substrate 10 is located within the orthographic projection of the through hole K1 within the second virtual quadrilateral Q2.

[0271] It is understandable that the first electrode 311 and the second electrode 312 are connected to different thin-film transistors 40, that is, the first electrode connection portion 51 and the second electrode connection portion 52 are electrically connected to different thin-film transistors 40. The electrical connection portions 221b corresponding to the first electrode 311 and the second electrode 312 within a virtual quadrilateral Q are respectively disposed in different through holes K1. This helps to reduce the number of electrical connection portions 221b arranged in a through hole, thereby reducing the area of ​​the through hole K1, reducing the distance between the first electrode 311, the second electrode 312 and the third electrode 313, thereby reducing the area of ​​the corresponding sub-pixel and improving the resolution of the display panel.

[0272] In some embodiments, the electrode connection portion 50 further includes a third electrode connection portion 53, through which the third electrode 313 is connected to the thin-film transistor 40. Within the region corresponding to the virtual quadrilateral Q, there are two third electrodes 313 and two third electrode connection portions 53. The orthographic projections of the two third electrode connection portions 53 onto the substrate 10 can lie within the orthographic projection of the through-hole K1 outline within the same virtual quadrilateral Q. Alternatively, the two third electrode connection portions 53 can be configured such that one of the two third electrode connection portions 53 has its orthographic projection onto the substrate 10 within the orthographic projection of the through-hole K1 outline within the virtual quadrilateral Q, while the other has its orthographic projection onto the substrate within the orthographic projection of the through-hole K1 outline within a virtual quadrilateral adjacent to the virtual quadrilateral Q. For example, the virtual quadrilateral Q also includes a third virtual quadrilateral Q. The third virtual quadrilateral Q and the second virtual quadrilateral Q2 are arranged sequentially along the first direction X. The second virtual quadrilateral Q2 and the third virtual quadrilateral share the same third electrode 313. The orthographic projection of one of the two third electrode connection parts 53 on the substrate 10 is located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 in the second virtual quadrilateral Q2 on the substrate 10. The orthographic projection of the other third electrode connection part 53 on the substrate 10 is located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 in the third virtual quadrilateral Q on the substrate 10.

[0273] Figure 8This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application. Figure 9 This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application.

[0274] In some alternative embodiments, such as Figure 8 and Figure 9 As shown, the first electrode 311, the second electrode 312 and the third electrode 313 are arranged at intervals and extend in the same direction.

[0275] Optionally, such as Figure 9 As shown, the first electrode 311, the second electrode 312, and the third electrode 313 can be spaced apart along the second direction Y, and the first electrode 311, the second electrode 312, and the third electrode 313 all extend along the first direction X. Alternatively, as... Figure 8 As shown, the first electrode 311, the second electrode 312, and the third electrode 313 can be spaced apart along the first direction X, and all three electrodes extend along the second direction Y. Of course, the first electrode 311, the second electrode 312, and the third electrode 313 can also be arranged along other directions.

[0276] The above-described configuration in this embodiment simplifies the arrangement of the pixel electrodes 31, thereby reducing the fabrication difficulty of the pixel electrodes 31 and improving the fabrication yield of the array substrate 100.

[0277] In some alternative embodiments, such as Figure 8 As shown, the extension directions of the constant signal line 22 and the non-constant signal line 21 both intersect the extension directions of the first electrode 311, the second electrode 312, and the third electrode 313. Specifically, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10; and / or, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10.

[0278] Optionally, the extension direction of the constant signal line 22 and the non-constant signal line 21 is the first direction X, and the extension direction of the first electrode 311, the second electrode 312, and the third electrode 313 is the second direction Y. Alternatively, the extension direction of the constant signal line 22 and the non-constant signal line 21 is the second direction Y, and the extension direction of the first electrode 311, the second electrode 312, and the third electrode 313 is the first direction X.

[0279] In some embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10. Furthermore, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10. In other embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10. In still other embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10.

[0280] Optionally, the number of constant signal lines 22 that overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10 can be one or more. For example, the orthographic projections of multiple constant signal lines 22 on the substrate 10 may all overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10.

[0281] Optionally, the number of non-constant signal lines 21 that overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10 can be one or more. For example, the orthographic projections of multiple non-constant signal lines 21 on the substrate 10 may overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10.

[0282] Through the above-described configuration, this embodiment of the application allows a constant signal line 22 to be arranged below the first electrode 311, the second electrode 312, and the third electrode 313 during the wiring process, thereby increasing the wiring area of ​​the constant signal line 22 and increasing the overlap area between the constant signal line and the pixel electrode 31. At the same time, a non-constant signal line 21 can be arranged below the first electrode 311, the second electrode 312, and the third electrode 313 during the wiring process, which can increase the wiring area of ​​the non-constant signal line 21, increase the design flexibility of the circuit, and improve the applicability of the array substrate 100.

[0283] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along a first direction X and are spaced apart along a second direction Y. Among these, a first constant signal line 221 is provided between any two adjacent pairs of the first non-constant signal line 211 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222.

[0284] For example, the first non-constant signal line 211 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222 are arranged sequentially at intervals along the second direction Y. Furthermore, a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the first electrode 311 and the first non-constant signal line 211 corresponding to the second electrode 312, a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the second electrode 312 and the first non-constant signal line 211 corresponding to the third electrode 313, and a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the third electrode 313 and the second constant signal line 222.

[0285] In some alternative embodiments, the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the first electrode 311 onto the substrate 10; and / or, the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of the first non-constant signal line 211 corresponding to the third electrode 313 onto the substrate 10 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the first electrode 311 onto the substrate 10.

[0286] Optionally, the center line of the first electrode 311 along the first direction X can be the center line of the second electrode 312 along the first direction X, or it can be the center line of the third electrode 313 along the first direction X.

[0287] In some optional embodiments, the first constant signal line 221 corresponding to the first electrode 311, the first constant signal line 221 corresponding to the second electrode 312, and the first constant signal line 221 corresponding to the third electrode 313 are sequentially arranged along the second direction Y on the substrate 10. The orthogonal projection of the first constant signal line 221 corresponding to the second electrode 312 on the substrate 10 passes through the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X, and is symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X. The orthogonal projections of the first constant signal line 221 corresponding to the first electrode 311 and the first constant signal line 221 corresponding to the third electrode 313 on the substrate 10 are symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X.

[0288] Optionally, the light-emitting units 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313 can form pixel units, and a light-transmitting area can be formed between two adjacent pixel units along the second direction Y. Optionally, the display panel 200 can include a light-transmitting area, and within the light-transmitting area, the light-transmitting area between two adjacent pixels can be used for light transmission.

[0289] In some alternative embodiments, such as Figure 9 As shown, the extension directions of the constant signal line 22 and the non-constant signal line 21 are the same as the extension directions of the first electrode 311, the second electrode 312, and the third electrode 313. Specifically, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10; and / or, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10.

[0290] Optionally, the extension direction of the constant signal line 22 and the non-constant signal line 21 is a first direction X, and the extension direction of the first electrode 311, the second electrode 312 and the third electrode 313 is also a first direction X. Alternatively, the extension direction of the constant signal line 22 and the non-constant signal line 21 is a second direction Y, and the extension direction of the first electrode 311, the second electrode 312 and the third electrode 313 is also a second direction Y.

[0291] For example, multiple constant signal lines 22 are spaced apart along the second direction Y, and the multiple constant signal lines 22 along the second direction Y are sequentially a first constant signal line 22, a second constant signal line 22, and a third constant signal line. A first electrode 311, a second electrode 312, and a third electrode 313 are sequentially arranged along the second direction Y. The orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the second constant signal line 22 onto the substrate 10. Alternatively, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the second constant signal line 22 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the third constant signal line 22 onto the substrate 10.

[0292] For example, multiple non-constant signal lines 21 are spaced apart along the second direction Y, and the multiple non-constant signal lines 21 are sequentially designated as a first non-constant signal line 21, a second non-constant signal line 21, and a third non-constant signal line along the second direction Y. A first electrode 311, a second electrode 312, and a third electrode 313 are sequentially arranged along the second direction Y. The orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the second non-constant signal line 21 onto the substrate 10. Alternatively, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the second non-constant signal line 21 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the third non-constant signal line 21 onto the substrate 10.

[0293] In some embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10; and the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10. In other embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10. In still other embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10.

[0294] This embodiment of the application reduces the size of the pixel electrode 31 in the arrangement direction and increases the size of the pixel electrode 31 in its extension direction through the above arrangement, thereby increasing the overlap area between the pixel electrode 31 and the single constant signal line 22 and the single non-constant signal line 21, reducing the capacitive coupling effect between the pixel electrode 31 and different constant signal lines 22, further reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, improving the display effect of the corresponding light-emitting unit 70, and improving the reliability of the display panel.

[0295] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along the first direction X and are spaced apart along the second direction Y. The orthogonal projection of the first constant signal line 221 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 passes through the center line of the orthogonal projection of the first electrode 311 or the second electrode 312 onto the substrate 10 along the first direction X, and is symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 or the second electrode 312 onto the substrate 10 along the first direction X.

[0296] For example, the orthographic projection of the first constant signal line 221 corresponding to the first electrode 311 onto the substrate 10 passes through the centerline of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X, and the orthographic projection of the first constant signal line 221 onto the substrate 10 is symmetrically arranged with respect to the centerline of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X. And / or, the orthographic projection of the first constant signal line 221 corresponding to the second electrode 312 onto the substrate 10 passes through the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X, and the orthographic projection of the first constant signal line 221 onto the substrate 10 is symmetrically arranged with respect to the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X.

[0297] In some alternative embodiments, the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate and the orthographic projection of the second constant signal line 222 overlapping with the orthographic projection of the second electrode 312 onto the substrate 10 onto the substrate are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the second electrode 312 onto the substrate 10.

[0298] For example, the orthographic projection of a second constant signal line 222 onto the substrate 10 overlaps with the orthographic projection of the second electrode 312 onto the substrate 10, and the overlapping portion of the orthographic projection of the second constant signal line 222 onto the substrate 10 and the orthographic projection of the second electrode 312 onto the substrate 10 and the first non-constant signal line 211 corresponding to the second electrode 312 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the second electrode 312 onto the substrate 10.

[0299] In some embodiments, the second constant signal line 222 has a mesh structure. For example, a portion of the multiple second constant signal lines 222 extends along a first direction X, and another portion of the multiple second constant signal lines 222 extends along a second direction Y. The second constant signal line 222 extending along the first direction X is on the same layer as the first constant signal line 221, and the second constant signal line 222 extending along the second direction Y is on a different layer from the second constant signal line 222 extending along the first direction X. A via structure may be provided between the second constant signal line 222 extending along the second direction Y and the second constant signal line 222 extending along the first direction X. The via structure may be located in the overlapping area of ​​the second constant signal line 222 and the pixel electrode 31. The symmetry of the second constant signal line 222 with other signal lines about the center line of the pixel electrode 31 along the first direction X refers to the extension structure of the second constant signal line 222, excluding the via structure. Similarly, the first non-constant signal line 211 and the first constant signal line 221 may also include via structures. The first non-constant signal line 211 and the first constant signal line 221 are symmetrical with other signal lines along the center line of the first direction X with the orthogonal projection of the pixel electrode 31 on the substrate 10, just as the second constant signal line 222 is symmetrical with other signal lines.

[0300] In some alternative embodiments, the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the center line of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X is equal to the distance between the orthographic projection of the second constant signal line 222 overlapping with the orthographic projection of the second electrode 312 onto the substrate 10 onto the center line of the second electrode 312 onto the substrate 10 along the first direction X.

[0301] In some optional embodiments, the first constant signal line 221 corresponding to the third electrode 313 includes a first branch, a second branch, and a connecting line. Both the first and second branches extend along a first direction X and are spaced apart along a second direction Y. The first and second branches are connected by the connecting line. The orthographic projection of the third electrode 313 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 211 used to drive the pixel circuit of the first electrode 311 onto the substrate 10. The orthographic projection of the first branch onto the substrate 10 passes through the center line of the orthographic projection of the third electrode 313 onto the substrate 10 along the first direction X and is perpendicular to the third electrode 313. The first non-constant signal line 211 corresponding to the third electrode 313 is symmetrically arranged on the substrate 10 along the center line of the first direction X, with the projection of the first non-constant signal line 211 on the substrate 10 and the projection of the second branch line on the substrate 10 being symmetrically arranged with the projection of the third electrode 313 on the substrate 10 along the center line of the first direction X. The second constant signal line 222 overlapping with the projection of the third electrode 313 on the substrate 10 and the projection of the first non-constant signal line 211 used to drive the pixel circuit of the first electrode 311 on the substrate 10 are symmetrically arranged with the projection of the third electrode 313 on the substrate 10 along the center line of the first direction X.

[0302] Optionally, the orthographic projections of a first branch line, a second branch line, and a connecting line on the substrate 10 all overlap with the orthographic projection of the same third electrode 313 on the substrate 10. Optionally, a first branch line, a second branch line, and a connecting line connecting the first and second branches form a repeating structure. A first constant signal line 221 may include multiple repeating structures. A constant signal line 22 is connected to multiple pixel circuits driving the third electrode 313. The multiple repeating structures and multiple third electrodes 313 are configured in a one-to-one correspondence.

[0303] Optionally, a first branch and a second branch can be connected by one or more connecting lines.

[0304] For example, the orthographic projection of the first branch on the substrate 10 passes through the center line of the orthographic projection of the third electrode 313 on the substrate 10 along the first direction X, and the orthographic projection of the first branch on the substrate 10 is symmetrically arranged with respect to the center line of the orthographic projection of the third electrode 313 on the substrate 10 along the first direction X.

[0305] The above-described configuration in this embodiment facilitates symmetrical arrangement of signal lines on the side of the third electrode 313 facing the substrate 10, improves the flatness of the third electrode 313, and reduces the possibility of color shift in the light-emitting unit 70 corresponding to the third electrode 313 under different viewing angles.

[0306] In some alternative embodiments, the overlapping area of ​​the first electrode 311 and the first constant signal line 221 projected onto the substrate 10 is greater than the overlapping area of ​​the second electrode 312 and the first constant signal line 221 projected onto the substrate 10, and the overlapping area of ​​the second electrode 312 and the first constant signal line 221 projected onto the substrate 10 is greater than the overlapping area of ​​the third electrode 313 and the first constant signal line 221 projected onto the substrate 10.

[0307] In some optional embodiments, the light-emitting units 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313 form pixel units, and the arrangement of the constant signal lines 22 and the non-constant signal lines 21 corresponding to the pixel units is the same as the arrangement of the pixel units.

[0308] For example, multiple pixel units are arranged in an array along the first direction X and the second direction Y. The constant signal line 22 corresponding to the first electrode 311, the non-constant signal line 21 corresponding to the first electrode 311, the constant signal line 22 corresponding to the second electrode 312, the non-constant signal line 21 corresponding to the second electrode 312, the constant signal line 22 corresponding to the third electrode 313, and the non-constant signal line 21 corresponding to the third electrode 313 are arranged in an array as a sub-unit along the first direction X and the second direction Y.

[0309] Figure 10 This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application.

[0310] In some alternative embodiments, such as Figure 10 As shown, the first electrode 311 and the second electrode 312 are spaced apart along the first direction X, and the third electrode 313 is located on the same side of the adjacent first electrode 311 and the second electrode 312 along the second direction Y. The third electrode 313 is spaced apart from the adjacent first electrode 311 and the second electrode 312 along the second direction Y. The first direction X, the second direction and the thickness direction Z of the array substrate 100 intersect each other.

[0311] For example, the first electrode 311, the second electrode 312 and the third electrode 313 are arranged in a triangular pattern.

[0312] Optionally, the area of ​​the third electrode may be greater than or equal to the sum of the areas of the first electrode 311 and the second electrode 312.

[0313] The embodiments of this application, through the above-described settings, facilitate the increase in the arrangement of the corresponding light-emitting units 70, improve the design flexibility of the light-emitting units, and broaden the applicability of the display panel.

[0314] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 extending along a first direction X; wherein the overlapping area of ​​the orthographic projection of the first electrode 311 and the first constant signal line 221 on the substrate 10 is smaller than the overlapping area of ​​the orthographic projection of the second electrode 312 and the first constant signal line 221 on the substrate 10, and the overlapping area of ​​the orthographic projection of the second electrode 312 and the first constant signal line 221 on the substrate 10 is smaller than the overlapping area of ​​the orthographic projection of the third electrode 313 and the first constant signal line 221 on the substrate 10.

[0315] Optionally, the orthographic projection of the first electrode 311 onto the substrate 10 may overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the first electrode 311 onto the substrate 10. The orthographic projection of the first electrode 311 onto the substrate 10 may also overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the second electrode 312 onto the substrate 10. It is understood that when the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with both the first constant signal line 221 driving the pixel circuit of the first electrode 311 and the first constant signal line 221 driving the pixel circuit of the second electrode 312, the sum of their overlapping areas is the overlapping area of ​​the orthographic projections of the first electrode 311 and the first constant signal line 221 onto the substrate 10.

[0316] Optionally, the orthographic projection of the second electrode 312 onto the substrate 10 may overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the second electrode 312 onto the substrate 10. The orthographic projection of the second electrode 312 onto the substrate 10 may also overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the first electrode 311 onto the substrate 10. It is understood that when the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with both the first constant signal line 221 driving the pixel circuit of the first electrode 311 and the first constant signal line 221 driving the pixel circuit of the second electrode 312, the sum of their overlapping areas is the overlapping area of ​​the orthographic projections of the second electrode 312 and the first constant signal line 221 onto the substrate 10.

[0317] In some alternative embodiments, the first constant signal line 221 includes a surface signal portion 221a, the area of ​​which is equal to ...

[0318] It is understandable that the area of ​​the surface signal section 221a corresponding to the second electrode 312 is smaller than the area of ​​the surface signal section 221a corresponding to the third electrode 313.

[0319] In some alternative embodiments, the orthographic projection of a portion of the surface signal portion 221a corresponding to the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first electrode 311 onto the substrate 10, and the orthographic projection of another portion of the surface signal portion 221a corresponding to the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the second electrode 312 onto the substrate 10.

[0320] In some alternative embodiments, the orthographic projection of the surface signal portion 221a corresponding to the second electrode 312 onto the substrate 10 overlaps with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10.

[0321] For example, a surface signal unit 221a includes three regions, one of which has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the first electrode 311 on the substrate 10, one of which has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the second electrode 312 on the substrate 10, and the last region has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the third electrode 313 on the substrate 10.

[0322] In some alternative embodiments, the surface signal portions 221a corresponding to the same type of pixel electrode 31 in adjacent pixel electrodes 31 are connected to form a whole surface structure.

[0323] For example, a surface signal portion 221a corresponding to a third electrode 313 is connected to a surface signal portion 221a corresponding to an adjacent third electrode 313 to form a full-surface structure.

[0324] Optionally, a third electrode 313 may correspond to a plurality of surface signal portions 221a. For example, a third electrode 313 may correspond to two surface signal portions 221a. The area of ​​one of the surface signal portions 221a corresponding to the third electrode 313 may be larger than the area of ​​the surface signal portion 221a corresponding to the first electrode 311. The area of ​​the other surface signal portion 221a corresponding to the third electrode 313 may be equal to the area of ​​the surface signal portion 221a used to drive the pixel circuit of the second electrode 312 that overlaps with the orthographic projection of the first electrode 311 on the substrate 10. And / or, the area of ​​one of the two surface signal portions 221a corresponding to the third electrode 313 may be greater than the area of ​​the surface signal portion 221a corresponding to the second electrode 312, and the area of ​​the other surface signal portion 221a corresponding to the third electrode 313 may be equal to the area of ​​the surface signal portion 221a used to drive the pixel circuit of the first electrode 311 that overlaps with the orthographic projection of the second electrode 312 on the substrate 10.

[0325] In some alternative embodiments, such as Figures 7 to 10 As shown, the constant signal line 22 includes a first part 223 and a second part 224 connected to each other. The first part is larger in the width direction than the second part 224. The orthographic projection of the first part 223 onto the substrate 10 overlaps at least partially with the orthographic projection of the pixel electrode 31 onto the substrate.

[0326] In some embodiments, the orthographic projection of the first portion 223 onto the substrate 10 overlaps with the orthographic projection of the pixel electrode 31 onto the substrate. In other embodiments, a portion of the orthographic projection of the first portion 223 onto the substrate 10 overlaps with a portion of the orthographic projection of the pixel electrode 31 onto the substrate.

[0327] In some embodiments, the first part 223 includes a surface signal part 221a, and the second part 224 includes a connection part 221b.

[0328] In some embodiments, the number of first portions 223 may include multiple, and adjacent first portions may be connected by second portions 224.

[0329] In this embodiment, by setting the first part 223, the overlap area between the constant signal line 22 and the pixel electrode 31 is further increased. Combined with different pixel electrode arrangement methods, the capacitive coupling effect between the constant signal line 22 and the pixel electrode 31 in the array substrate 100 with different design requirements can be enhanced. By setting the second part 224, the space occupied by the constant signal line 22 in the array substrate 100 is adaptively reduced, the flexibility of the wiring design of the constant signal line 22 is improved, and the applicability of the array substrate 100 is increased.

[0330] Figure 11 This is a cross-sectional structural diagram of another array substrate 100 provided in the embodiments of this application.

[0331] In some alternative embodiments, such as Figure 7 and Figure 11 As shown, constant signal lines 22 and non-constant signal lines 21 are arranged on the same layer, thereby reducing the number of signal line layer groups 20, reducing the overall thickness of the array substrate 100, and achieving a thinner and lighter display panel.

[0332] Optionally, the signal line layer group 20 includes multiple signal line layers. For example, the signal line layer group includes four layers, which are sequentially arranged in the direction away from the substrate 10 as a first signal line layer, a second signal line layer, a third signal line layer, and a fourth signal line layer, with constant signal line 22 and non-constant signal line 21 located in the fourth signal line layer.

[0333] Figure 12This is a cross-sectional structural diagram of another array substrate 100 provided in the embodiments of this application.

[0334] In some alternative embodiments, such as Figure 7 and Figure 12 As shown, the distance between pixel electrode 31 and non-constant signal line 21 is greater than the distance between pixel electrode 31 and constant signal line 22.

[0335] For example, the non-constant signal line 21 and the constant signal line 22 are located in different signal line layer groups 20. For instance, the constant signal line 22 is located in the third signal line layer, and the non-constant signal line 21 is located in the fourth signal line layer.

[0336] The embodiments of this application, through the above-described settings, facilitate increasing the distance between the non-constant signal line 21 and the pixel electrode 31, thereby reducing the capacitance between the non-constant signal line 21 and the pixel electrode 31, further reducing the capacitive coupling effect between the non-constant signal line 21 and the pixel electrode 31, reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, and improving the reliability of the array substrate 100.

[0337] Figure 13 This is a cross-sectional structural diagram of another array substrate 100 provided in the embodiments of this application.

[0338] In some alternative embodiments, such as Figure 13 As shown, the non-constant signal line 21 is located between the constant signal line 22 and the substrate 10.

[0339] Optionally, the non-constant signal line 21 is located between the constant signal line 22 and the substrate 10, and the orthographic projection of the non-constant signal line 21 onto the substrate 10 overlaps at least partially with the orthographic projection of the constant signal line onto the substrate, so that the constant signal line 22 can play a shielding role. The constant signal line 22 can effectively shield the electric field between the pixel electrode 31 and the non-constant signal line 21, reduce the influence of capacitive coupling between the pixel electrode and the non-constant signal line, and improve the reliability of the array substrate 100.

[0340] Figure 14 This is a cross-sectional structural diagram of another array substrate 100 provided in the embodiments of this application.

[0341] In some alternative embodiments, such as Figure 14 As shown, a shielding structure E1 is provided between the non-constant signal line 21 and the pixel electrode 31, and the shielding structure is electrically connected to the constant voltage terminal.

[0342] Optionally, the non-constant signal line 21 and the constant signal line 22 are located on the same layer, and a shielding structure E1 is provided between the non-constant signal line 21 and the pixel electrode 31, so that the shielding structure can effectively shield the electric field between the pixel electrode 31 and the non-constant signal line 21, reduce the influence of capacitive coupling between the pixel electrode and the non-constant signal line, and improve the reliability of the array substrate 100.

[0343] Optionally, the shielding structure E1 can be directly connected to the constant voltage terminal, or the shielding structure can be electrically connected to the constant voltage terminal through the constant signal line 22.

[0344] Optionally, the shielding structure E1 can be a full-surface structure or a block structure. For example, the shielding structure E1 can be a conductive block.

[0345] In some optional embodiments, a first insulating portion is provided between the non-constant signal line 21 and the pixel electrode 31, and a second insulating portion is provided between the constant signal line and the pixel electrode, wherein the dielectric constant of the first insulating portion is less than the dielectric constant of the second insulating portion.

[0346] Optionally, the dielectric constant of the insulating material can be adjusted by replacing the insulating material with a different insulating material; for example, the materials of the first insulating part and the second insulating part can be different.

[0347] Optionally, the first insulating portion and the second insulating portion may be located in the same film layer, or the first insulating portion and the second insulating portion may be located in different film layers. In some optional embodiments, the capacitance between the non-constant signal line 21 and the pixel electrode 31 is less than the capacitance between the constant signal line 22 and the pixel electrode 31.

[0348] The embodiments of this application, through the above-described settings, help to reduce the capacitance between the non-constant signal line 21 and the pixel electrode 31, and increase the capacitance between the constant signal line 22 and the pixel electrode 31, thereby reducing the capacitive coupling effect between the non-constant signal line 21 and the pixel electrode, reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, and improving the reliability of the array substrate 100.

[0349] Secondly, please refer to Figure 1 , Figure 2 as well as Figures 8 to 10This application provides an array substrate 100. The array substrate 100 includes a substrate 10, a signal line layer group 20, and a first electrode layer 30. The signal line layer group 20 is located on one side of the substrate and includes non-constant signal lines 21 and constant signal lines, both of which extend along a first direction X. The first electrode layer 30 is located on the side of the signal line layer group 20 facing away from the substrate 10 and includes a plurality of pixel electrodes 31. Specifically, along the width direction of the constant signal line 22, at least a portion of the orthographic projection of the constant signal line onto the substrate 10 lies within the orthographic projection of the pixel electrode 31 onto the substrate, and at least a portion of the edge of the constant signal line 22 away from the centroid of the pixel electrode lies within the orthographic projection of the corresponding pixel electrode 31 onto the substrate.

[0350] In some embodiments, at least a portion of the orthographic projection of the constant signal line 22 onto the substrate 10 lies within the orthographic projection of the pixel electrode 31 onto the substrate 10 along its own width direction. This means that a portion or all of the orthographic projection of the constant signal line 22 onto the substrate along the second direction Y lies within the orthographic projection of the pixel electrode 31 onto the substrate 10. Optionally, the width direction of the constant signal line 22 is parallel to the second direction Y.

[0351] Optionally, the constant signal line 22 includes a first edge and a second edge disposed opposite to each other along its width direction. The first edge and the second edge are located on the same side of the centroid along the second direction Y, and the second edge is located on the side of the first edge facing away from the centroid. Along the second direction Y, the orthographic projection of the second edge onto the substrate 10 lies within the orthographic projection of the pixel electrode 31 onto the substrate 10. Of course, the orthographic projection of the first edge onto the substrate 10 also lies within the orthographic projection of the pixel electrode 31 onto the substrate 10.

[0352] The arrangement of the substrate, signal line layer group 20, and first electrode layer 30 is as described in the above-mentioned display panel embodiment, and will not be repeated here.

[0353] In some alternative embodiments, such as Figure 5 As shown, along the second direction Y, the distance between two adjacent pixel electrodes 31 is D, and the minimum distance between the orthographic projection of the edge of the constant signal line away from the centroid of the pixel electrode 31 and the orthographic projection of the edge of the pixel electrode 31 extending along the first direction X is d. D and d satisfy the relationship: 0.05≤d / D≤0.5.

[0354] For example, the edge of the orthographic projection of the pixel electrode 31 onto the substrate 10 extending along the first direction X is the third edge, and the minimum distance between the orthographic projection of the third edge onto the substrate 10 and the orthographic projection of the second edge onto the substrate is d.

[0355] Optionally, the ratio of the minimum distance between the orthographic projection of the edge of the constant signal line away from the centroid of the pixel electrode 31 and the orthographic projection of the edge of the pixel electrode 31 extending along the first direction X, and the distance between two adjacent pixel electrodes 31 along the second direction is 0.05, 0.1, 0.3, or 0.5.

[0356] In this embodiment, the minimum distance between the orthographic projection of the edge of the constant signal line away from the centroid of the pixel electrode 31 and the orthographic projection of the edge of the pixel electrode 31 extending along the first direction X, and the distance between two adjacent pixel electrodes 31 along the second direction are greater than or equal to 0.05, thereby reducing the distance between the light-emitting units 70 in the display panel and improving the resolution of the display panel. Furthermore, the ratio of the minimum distance between the orthographic projection of the edge of the constant signal line away from the centroid of the pixel electrode 31 and the orthographic projection of the edge of the pixel electrode 31 extending along the first direction X, and the distance between two adjacent pixel electrodes 31 along the second direction, is less than or equal to 0.5, thereby increasing the area of ​​the pixel electrode 31 covering the constant signal line 22, thereby enhancing the capacitive coupling effect between the pixel electrode 31 and the constant signal line, improving the stability of the pixel electrode voltage, and thus improving the reliability of the array substrate 100.

[0357] In some alternative embodiments, such as Figure 3 As shown, the pixel electrode 31 includes a first electrode 311, a second electrode 312, and a third electrode 313, which are respectively disposed corresponding to light-emitting units 70 of different colors.

[0358] This application embodiment does not limit the color of the light-emitting unit 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313. Exemplarily, the light-emitting unit 70 includes different colors; for example, the light-emitting unit 70 includes a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit 70. Optionally, the first electrode 311 may correspond to the red light-emitting unit 70, the second electrode 312 may correspond to the blue light-emitting unit 70, and the third electrode 313 may correspond to the green light-emitting unit 70. Optionally, the light-emitting unit may also include a white light-emitting unit, and one of the first electrode 311, the second electrode 312, and the third electrode 313 may also correspond to the white light-emitting unit 70.

[0359] The embodiments of this application do not limit the shape and size of the first electrode 311, the second electrode 312, and the third electrode 313. Exemplarily, the first electrode 311, the second electrode 312, and the third electrode 313 may have the same shape, or they may have different shapes, or two of them may be the same, or all three may be different.

[0360] The embodiments of this application, through the above-described settings, help reduce the possibility of crosstalk between the pixel electrodes 31 corresponding to different color light-emitting units 70 and the non-constant signal lines 21, improve the stability of the display effect of different color light-emitting units 70, and thus improve the reliability of the display panel.

[0361] In some alternative embodiments, such as Figures 1 to 4 As shown, the centroids of a first electrode 311, a second electrode 312, and two third electrodes 313 are respectively arranged at the four vertices of the virtual quadrilateral Q.

[0362] In other words, the line connecting the centers of an adjacent first electrode 311, a second electrode 312, and two third electrodes 313 can form a virtual quadrilateral Q. In some embodiments, the first electrode 311 and the second electrode 312 can be arranged at two facing vertices of the virtual quadrilateral Q. The two third electrodes 313 can be arranged at two facing vertices of the virtual quadrilateral Q. The virtual quadrilateral can be a rectangle, a rhombus, a square, etc.

[0363] It is understandable that a first electrode 311, a second electrode 312, and two third electrodes 313 are respectively arranged at the four vertices of the virtual quadrilateral Q, and the corresponding color light-emitting unit 70 is also arranged at the four vertices of the virtual quadrilateral Q, thereby forming the sub-pixel arrangement structure in the display panel. Furthermore, through this sub-pixel arrangement structure, color rendering can be driven by sharing adjacent sub-pixels, and high resolution can be achieved with a small number of pixels.

[0364] In some embodiments, such as Figure 3 As shown, in the region corresponding to the virtual quadrilateral Q, two third electrodes 313 are spaced apart along the first direction X, and the first electrode 311 and the second electrode 312 are spaced apart along the second direction Y. The first direction X, the second direction, and the thickness direction Z of the array substrate 100 intersect each other. Optionally, the first direction X, the second direction Y, and the thickness direction Z of the array substrate 100 are perpendicular to each other.

[0365] Within a virtual quadrilateral Q, that is, for a virtual quadrilateral, two third electrodes 313 are spaced apart along a first direction X, and a first electrode 311 and a second electrode 312 are spaced apart along a second direction Y. At least a portion of the orthographic projection of the first electrode onto the first plane and at least a portion of the orthographic projection of the second electrode 312 onto the first plane are located between the orthographic projections of the two third electrodes 313 onto the first plane. The first plane is a plane perpendicular to the second direction Y. Optionally, the centroid of the first electrode 311 passes through a perpendicular line perpendicular to the midpoint of the line connecting the centroids of the two third electrodes 313. The centroid of the second electrode 312 passes through a perpendicular line perpendicular to the midpoint of the line connecting the centroids of the two third electrodes 313. Optionally, the line connecting the centroids of the first electrode 311 and the second electrode 312 can be parallel to or intersect the second direction Y.

[0366] In some alternative embodiments, such as Figures 2 to 4 As shown, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along a first direction X and are spaced apart along a second direction Y. Specifically, the orthographic projection of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10 overlaps at least with the orthographic projection of the first electrode 311 onto the substrate 10; the orthographic projection of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10 overlaps at least with the orthographic projection of the second electrode 312 onto the substrate; and the orthographic projection of the first non-constant signal line 211 onto the substrate 10 overlaps at least with the orthographic projections of the first electrode 311 and the second electrode 312 onto the substrate 10.

[0367] Optionally, the functions of the first constant signal line 221 and the second constant signal line 222 are different.

[0368] Optionally, the number of first constant signal lines 221 may include one or more.

[0369] Optionally, the number of second constant signal lines 222 may include one or more.

[0370] Optionally, the number of the first non-constant signal lines 211 may include one or more.

[0371] Optionally, the constant signal line 22 may also include a third constant signal line 22, a fourth constant signal line 22, or more.

[0372] Optionally, the non-constant signal line 21 may also include a second non-constant signal line 21, a third non-constant signal line 21, a fourth non-constant signal line 21, or more.

[0373] The embodiments of this application do not limit the arrangement of the first constant signal line 221, the second constant signal line 222, and the third constant signal line 22. For example, the first constant signal line 221, the second constant signal line 222, and the third constant signal line can be arranged alternately along the second direction Y, or they can be arranged according to a predetermined arrangement rule according to actual design requirements.

[0374] In some embodiments, the orthographic projections of the first constant signal line 221 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projections of the first constant signal line 221 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the second electrode 312 on the substrate. In other embodiments, the orthographic projections of the second constant signal line 222 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projections of the second constant signal line 222 and the first non-constant signal line 211 on the substrate 10 overlap with the orthographic projection of the second electrode 312 on the substrate. In some embodiments, the orthographic projections of the first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 onto the substrate 10 overlap with the orthographic projection of the first electrode 311 onto the substrate 10. Furthermore, the orthographic projections of the first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 onto the substrate 10 overlap with the orthographic projection of the second electrode 312 onto the substrate. In other embodiments, the orthographic projections of at least one of the first constant signal line 221 and the second constant signal line 222 onto the substrate 10, and the orthographic projection of the first non-constant signal line 211 onto the substrate 10 may also at least partially overlap with the orthographic projection of the third electrode 313 onto the substrate.

[0375] The embodiments of this application, through the above-described settings, help to reduce the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, while increasing the flexibility of the arrangement of the constant signal line 22 and the non-constant signal line 21, and improving the applicability of the array substrate 100.

[0376] In some alternative embodiments, the orthographic projection of the first constant signal line 221 on the substrate 10 and the orthographic projection of the second constant signal line 222 on the substrate 10 both overlap with the orthographic projection of the first electrode 311 on the substrate 10, and the orthographic projection of the first constant signal line 221 on the substrate 10 and the orthographic projection of the second constant signal line 222 on the substrate 10 both overlap with the orthographic projection of the second electrode 312 on the substrate.

[0377] In some optional embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction; and / or, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction.

[0378] The second constant signal line 222 corresponding to the first electrode 311, where "corresponding" refers to the second constant signal line 222 used to drive the first electrode 311, and the portion of the second constant signal line 222 overlapping the orthographic projection of the first electrode 311 on the substrate 10. Similarly, the "correspondence" in the first constant signal line 221 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the first electrode 311, the first constant signal line 221 corresponding to the second electrode 312, the second constant signal line 222 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the second electrode 312, the first constant signal line 221 corresponding to the third electrode 313, the second constant signal line 222 corresponding to the third electrode 313, and the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222 corresponding to the first electrode 311, is consistent and will not be described again.

[0379] In some embodiments, such as Figure 4As shown, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction. Furthermore, the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 is provided with a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its own width direction. Optionally, the two first non-constant signal lines 22 and the two first constant signal lines 221 can be symmetrically arranged with respect to the second constant signal line 222. For example, the arrangement of the two first non-constant signal lines 211, the two first constant signal lines 221, and the second constant signal line 222 along the second direction Y can be, in sequence, the first constant signal line 221, the first non-constant signal line 211, the second constant signal line 222, the first non-constant signal line 211, and the first constant signal line 221; or it can be, the first non-constant signal line 222, the first constant signal line 221, the second constant signal line 222, the first constant signal line 22, and the first non-constant signal line 211. Of course, the two first non-constant signal lines 22 and the two first constant signal lines 221 can also be asymmetrically arranged with respect to the second constant signal line 222. For example, the arrangement could be: the first constant signal line 221, the first non-constant signal line 211, the second constant signal line 222, the first constant signal line 221, and the first non-constant signal line 211.

[0380] In some embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the same second electrode 312 has a first constant signal line 221 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its width direction. In still other embodiments, the second constant signal line 222 corresponding to the first electrode 311 or the same second electrode 312 has a first non-constant signal line 211 corresponding to the same first electrode 311 or the same second electrode 312 on both sides along its width direction.

[0381] The width direction of the second constant signal line 222 can be a direction perpendicular to the extension direction of the second constant signal line.

[0382] In these alternative embodiments, by providing first constant signal lines 221 on both sides of the second constant signal line 222 along its width direction, it is beneficial to increase the overlap area between the constant signal line 22 and the pixel electrode 31, thereby reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode. By providing first non-constant signal lines 211 on both sides of the second constant signal line 222 along its width direction, it is beneficial to improve the design flexibility of the first non-constant signal lines and increase the applicability of the array substrate 100.

[0383] In some embodiments, the orthographic projections of multiple first constant signal lines 221 and / or multiple first non-constant signal lines 211 on the substrate 10 of the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 on both sides of its own width direction are symmetrically arranged with the center line of the first direction X as the axis of symmetry of the orthographic projection of the first electrode 311 on the substrate 10.

[0384] For example, the number of first constant signal lines 221 includes two, and the number of first non-constant signal lines 211 includes two. The orthographic projections of the two first constant signal lines 221 onto the substrate 10 are symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry. The orthographic projections of the two first non-constant signal lines 211 onto the substrate 10 are also symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry. Alternatively, the orthographic projections of one first constant signal line 221 onto the substrate 10 and one first non-constant signal line 211 onto the substrate 10 are symmetrically arranged with the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X as the axis of symmetry.

[0385] In some embodiments, the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the orthographic projection of the first electrode 311 onto the substrate 10 or the orthographic projection of the second electrode 312 onto the substrate 10 along the center line of the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0386] It is understandable that the orthographic projections of the first segment 211a and the second segment 211b onto the substrate 10 are both located within the orthographic projections of the first electrode 311 or the second electrode 312 onto the substrate 10.

[0387] For example, the first non-constant signal line 211 corresponding to the first electrode 311 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the center line of the orthographic projection of the first electrode 311 onto the substrate 10 along the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. Alternatively, the first non-constant signal line 211 corresponding to the second electrode 312 includes a first segment 211a and a second segment 211b connected together. The orthographic projection of the first segment 211a onto the substrate 10 intersects the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the second direction Y. The minimum distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. Optionally, when the orthographic projections of the second segment 211b onto the substrate 10 and the orthographic projections of the adjacent second constant signal line 222 onto the substrate 10 are designed to be equally spaced, the minimum distance between the orthographic projections of the second segment 211b onto the substrate 10 and the adjacent second constant signal line 222 onto the substrate 10 is also the distance between the orthographic projections of the second segment 211b onto the substrate 10 and the adjacent second constant signal line 222 onto the substrate 10. The second segment 211b and its adjacent second constant signal line 222 can also be designed with unequal spacing.

[0388] Optionally, the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are parallel.

[0389] Optionally, the second segment 211b and the second constant signal line 222 projected onto the substrate 10 are parallel to each other.

[0390] In some embodiments, the extension direction of the orthographic projection of the second segment 211b onto the substrate 10 intersects the extension direction of the orthographic projection of the second constant signal line 222 onto the substrate 10, and along a direction away from the centroid of the first electrode 311 or the second electrode 312, the distance between the orthographic projection of the second segment 211b onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 gradually increases.

[0391] Optionally, the orthographic projection of the second segment 211b onto the substrate 10 can be a straight line inclined relative to the extension direction of the orthographic projection of the second constant signal line 222 onto the substrate 10. The second segment 211b may also include multiple sub-segments, and the distance between the orthographic projection of the multiple sub-segments onto the substrate 10 and the orthographic projection of the adjacent constant signal line 22 onto the substrate 10 gradually increases along the direction away from the centroid of the first electrode 311 or the second electrode 312.

[0392] In some alternative embodiments, the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0393] For example, the first non-constant signal line 211 corresponding to the first electrode 311 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10. And / or, the first non-constant signal line 211 corresponding to the second electrode 312 further includes a third segment 211c, which is connected to the end of the first segment 211a away from the second segment 211b. The minimum distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 is greater than the maximum distance between the orthographic projection of the first segment 211a onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10.

[0394] In some alternative embodiments, the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are parallel.

[0395] In some alternative embodiments, the distance between the orthographic projection of the third segment 211c onto the substrate 10 and the orthographic projection of the adjacent second constant signal line 222 onto the substrate 10 gradually increases along a direction away from the centroid of the orthographic projection of the first electrode 311 onto the substrate 10 or the orthographic projection of the second electrode 312 onto the substrate 10.

[0396] For example, the distance between the third segment 211c and its adjacent second constant signal line 222 gradually increases from the centroid of the first electrode 311 towards its edge along the first direction X. And / or, the distance between the third segment 211c and its adjacent second constant signal line 222 gradually increases from the centroid of the second electrode 312 towards its edge along the first direction X. Here, "gradually increases" can be a step-like increase or a proportional increase. Through the above arrangement, a light-transmitting area can be formed between the second constant signal line 222 and the first non-constant signal line 211, thereby increasing the light transmittance of the display panel 200.

[0397] In some embodiments, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10.

[0398] For example, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10. And / or, along the second direction Y, the distance between the orthographic projection of the second constant signal line 222 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first non-constant signal line 211 onto the substrate 10 is equal to the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of its adjacent first constant signal line 221 onto the substrate 10. This arrangement helps to increase the flatness of the first electrode 311 and the second electrode 312, reducing the possibility of color shift in the light-emitting units 70 corresponding to the first electrode 311 and the second electrode 312 under different viewing angles.

[0399] In some embodiments, the first constant signal line 221 includes a power supply line. For example, the power supply line may be a first power supply line for transmitting a power supply voltage to the anode and a second power supply line for transmitting a power supply voltage to the cathode. The first constant signal line 221 is at least one of the first power supply line and the second power supply line.

[0400] In some embodiments, the second constant signal line 222 includes an initialization voltage line. For example, the initialization voltage line may be a first initialization voltage line for gate reset of the thin-film transistor 40 and a second initialization voltage line for anode reset. The second constant signal line 222 is at least one of the first initialization voltage line and the second initialization voltage line.

[0401] In some embodiments, the first non-constant signal line 211 includes a data line.

[0402] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, in the region corresponding to the virtual quadrilateral Q, a through hole K1 is provided on the first constant signal line 221, and the orthographic projection of the pixel electrode 31 on the substrate 10 and the orthographic projection of the through hole outline on the substrate at least partially overlap.

[0403] Optionally, a closed via K1 structure is provided on the first constant signal line 221. Optionally, the via can be circular, elliptical, rectangular, or other shapes.

[0404] Optionally, within a virtual quadrilateral Q, the number of through holes K1 can be one or more.

[0405] It is understood that within a virtual quadrilateral Q, a portion of the structures of the first electrode 311, the second electrode 312, and the third electrode 313 extend towards the center of the virtual quadrilateral Q to occupy a portion of the area within the virtual quadrilateral. The orthographic projection of the first electrode 311 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10. And / or, the orthographic projection of the second electrode 312 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10. And / or, the orthographic projection of the third electrode 313 onto the substrate 10 may at least partially overlap with the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate. Taking the first electrode 311 as an example, "at least partially overlap" here means that a portion of the orthographic projection of the first electrode onto the substrate 10 overlaps with a portion of the orthographic projection of the pattern enclosed by the outline of the through-hole K1 onto the substrate 10, or it could mean that the orthographic projection of the pattern enclosed by the outline of the through-hole onto the substrate 10 falls within the orthographic projection of the first electrode 311 onto the substrate.

[0406] The via profile K1 refers to the edge of the via K1 structure on the first constant signal line 221.

[0407] Optionally, the through hole can be located at the centroid of the virtual quadrilateral Q, or at any position on the virtual quadrilateral.

[0408] In these alternative embodiments, the above-described arrangement helps to increase the overlap area between the pixel electrode 31 and the first constant signal line 221, thereby enhancing the capacitive coupling effect between the pixel electrode 31 and the constant signal line 22, reducing the possibility of crosstalk between the pixel electrode and the non-constant signal line 21, improving the reliability of the array substrate 100, and thus improving the reliability of the display panel.

[0409] In some alternative embodiments, such as Figures 1 to 4 As shown, in the region corresponding to the virtual quadrilateral Q, the first constant signal line 221 includes a surface signal portion 221a and a connecting portion 221b that are connected to each other. The size of the surface signal portion along the second direction Y is larger than the size of the connecting portion 221b along the second direction. The surface signal portion 221a and the connecting portion enclose a through hole K1. The orthographic projection of the third electrode 313 on the substrate 10 and the orthographic projection of the surface signal portion 221a on the substrate are at least partially overlapped.

[0410] Optionally, the edge of the surface signal section 221a is at least partially located within the orthographic projection of the third electrode 313 onto the substrate 10.

[0411] Optionally, the edge of the surface signal section 221a includes a first side L1 extending along the first direction X, at least a portion of which is located within the orthographic projection of the third electrode onto the substrate 10.

[0412] Optionally, the orthographic projection of the first side L1 onto the substrate 10 is entirely within the orthographic projection of the third electrode onto the substrate 10.

[0413] Optionally, the first side L1 is a straight side.

[0414] Optionally, within a region corresponding to a virtual quadrilateral Q, the number of face signal units 221a may include one or more. When only one face signal unit 221a is provided within a region corresponding to a virtual quadrilateral Q, adjacent face signal units 221a within the same region are connected by a connecting part 221b. When multiple face signal units 221a are provided within a region corresponding to a virtual quadrilateral Q, the multiple face signal units 221a within the same region are connected by a connecting part 221b, and adjacent face signal units 221a within the same region are connected by a connecting part 221b. Here, "within the region corresponding to the virtual quadrilateral" refers to a region including a virtual quadrilateral and the face signal unit, connecting part, and other structures corresponding to that virtual quadrilateral.

[0415] The surface signal portion 221a and the connecting portion 221b enclose and form a through hole K1, and a portion of the edge of the surface signal portion and a portion of the edge of the connecting portion form the outline of the through hole.

[0416] Optionally, a portion of the orthographic projection of the third electrode 313 onto the substrate 10 overlaps with a portion of the orthographic projection of the surface signal portion 221a onto the substrate 10; or, the orthographic projection of the third electrode 313 onto the substrate 10 falls within the orthographic projection of the surface signal portion 221a onto the substrate 10; or, the orthographic projection of the surface signal portion onto the substrate 10 falls within the orthographic projection of the third electrode 313 onto the substrate.

[0417] In some embodiments, in the region corresponding to the virtual quadrilateral Q, two third electrodes 313 are spaced apart along the first direction X. By making the size of the surface signal portion 221a along the second direction Y larger than the size of the connecting portion 221b along the second direction, the overlap area of ​​the surface signal portion 221a and the third electrode 313 on the substrate 10 is increased. At the same time, by reducing the size of the third electrode 313 along the first direction X, the distance between the two third electrodes along the first direction is smaller, thereby reducing the overall area of ​​the virtual quadrilateral Q, and further reducing the area of ​​the sub-pixels in the display panel, thereby improving the resolution of the display panel.

[0418] like Figure 4 As shown, in the region corresponding to the virtual quadrilateral Q, there are two surface signal units 221a. The two surface signal units 221a are respectively disposed on both sides of the through hole K1 along the first direction X, and the two surface signal units are respectively disposed in a one-to-one correspondence with the two third electrodes 313.

[0419] Optionally, the two surface signal units 221a can be connected by one or more connecting units 221b.

[0420] In some alternative embodiments, such as Figure 2 and Figure 5 As shown, in the region corresponding to the virtual quadrilateral Q, at least one of the first electrode 311 and the second electrode 312 is disposed with its orthographic projection on the substrate 10 overlapping with the orthographic projection of the connecting portion 221b on the substrate.

[0421] In some embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the connecting portion 221b onto the substrate 10, and the orthographic projection of the second electrode 312 onto the substrate 10 overlaps with the orthographic projection of the connecting portion 221b onto the substrate. In other embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the connecting portion 221b onto the substrate. In still other embodiments, within the region corresponding to the virtual quadrilateral Q, the orthographic projection of the second electrode 312 onto the substrate 10 overlaps with the orthographic projection of the connecting portion 221b onto the substrate.

[0422] It is understandable that when the orthographic projections of the first electrode 311 and the second electrode 312 on the substrate 10 both overlap with the orthographic projections of the connecting portion 221b on the substrate 10, the orthographic projections of the first electrode 311 on the substrate 10 and the orthographic projections of the second electrode 312 on the substrate 10 overlap with the orthographic projections of different connecting portions 221b on the substrate, respectively.

[0423] The embodiments of this application, through the above-described configuration, facilitate an increase in the overlap area between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, thereby reducing the possibility of crosstalk between the first electrode 311 and / or the second electrode 312 and the non-constant signal line 21, and further reducing the possibility of display abnormalities in the light-emitting unit 70 corresponding to the first electrode 311 and / or the second electrode 312, thus improving the reliability of the display panel.

[0424] In the region corresponding to the virtual quadrilateral Q, there are two connecting portions 221b. The two connecting portions 221b are respectively disposed on both sides of the through hole K1 along the second direction Y. The orthographic projection of one of the connecting portions 221b on the substrate 10 overlaps at least partially with the orthographic projection of the first electrode 311 on the substrate. The orthographic projection of the other connecting portion 221b on the substrate 10 overlaps at least partially with the orthographic projection of the second electrode 312 on the substrate.

[0425] Optionally, both connecting portions 221b can be electrically connected to the surface signal portions 221a located on both sides of the through hole K1 along the first direction X. Alternatively, only one connecting portion 221b can be electrically connected to the surface signal portions 221a located on both sides of the through hole K1 along the first direction X, and the other connecting portion 221b can be electrically connected to only one of the two surface signal portions 221a located on both sides of the through hole K1 along the first direction X, or the other connecting portion 221b can be not electrically connected to the surface signal portion 221a. Of course, neither connecting portion can be electrically connected to the surface signal portion.

[0426] In these alternative embodiments, the above-described arrangement helps to further increase the overlap area between all pixel electrodes 31 and constant signal lines 22, thereby reducing the possibility of crosstalk between all pixel electrodes and non-constant signal lines 21 and improving the overall display effect of the display panel.

[0427] In some alternative embodiments, such as Figures 2 to 5 As shown, in the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of at least one of the first electrode 311 and the second electrode 312 on the substrate 10 overlaps with the orthographic projection of the pattern formed by the outline of the through hole K1 on the substrate.

[0428] Optionally, the connecting portion 221b may include a first connecting portion 221b1 and a second connecting portion 221b2, wherein the orthographic projection of the first electrode 311 on the substrate 10 at least partially overlaps with the orthographic projection of the first connecting portion 221b1 on the substrate 10, and the orthographic projection of the second electrode 312 on the substrate 10 at least partially overlaps with the orthographic projection of the second connecting portion 221b2 on the substrate.

[0429] In some embodiments, within the region corresponding to the virtual quadrilateral Q, a portion of the first electrode 311 extends along the second direction Y and toward the centroid of the through hole K1, such that the first electrode 311 includes a first region, a second region, and a third region. The orthographic projection of the first region onto the substrate 10 is located on the side of the orthographic projection of the first connection portion 221b1 onto the substrate 10 away from the outline of the through hole K1. The orthographic projection of the second region onto the substrate 10 overlaps with the orthographic projection of the first connection portion 221b1 onto the substrate 10. The orthographic projection of the third region onto the substrate 10 overlaps with the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10. Furthermore, the orthographic projection of a portion of the third region onto the substrate 10 is located within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate. The overlap relationship between the second electrode 312 and the pattern enclosed by the outline of the through hole K1 is the same as that between the first electrode 311 and the pattern enclosed by the through hole outline, and will not be repeated in this embodiment.

[0430] In some embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projections of the first electrode 311 and the second electrode 312 onto the substrate 10 both exceed the orthographic projection of the connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10. In other embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the first electrode 311 onto the substrate 10 exceeds the orthographic projection of the first connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10. In still other embodiments, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the second electrode 312 onto the substrate 10 exceeds the orthographic projection of the second connecting portion 221b2 onto the substrate 10 and the orthographic projection of the pattern formed by the outline of the through hole K1 onto the substrate 10.

[0431] The embodiments of this application, through the above-described configuration, facilitate an increase in the overlap area between the first electrode 311 and / or the second electrode 312 and the connecting portion 221b, thereby increasing the overlap area between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, enhancing the capacitive coupling effect between the first electrode 311 and / or the second electrode 312 and the constant signal line 22, reducing the possibility of crosstalk between the pixel electrode 31 and the non-constant signal line 21, and improving the reliability of the display panel.

[0432] In some embodiments, such as Figure 5 and Figure 6 As shown,

[0433] The edge of at least one of the first electrode 311 and the second electrode 312 includes a second side L2, and at least a portion of the second side L2 is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through hole K1 within the orthographic projection of the substrate 10. In some embodiments, the second side L2 extends along a first direction X.

[0434] When, within the region corresponding to the virtual quadrilateral Q, along the second direction Y, the orthographic projection of the first electrode 311 onto the substrate 10 exceeds the orthographic projection of the first connecting portion 221b1 onto the substrate 10 and the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10, at least a portion of the orthographic projection of the second side L2 onto the substrate 10 lies within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the substrate 10. The overlap relationship between the second electrode 312 along the second direction Y, including the second side L2, and the pattern enclosed by the outline of the through hole K1 is the same as the overlap relationship between the first electrode 311 along the second direction Y, including the second side L2, and the pattern enclosed by the outline of the through hole K1, but it can also be different.

[0435] Optionally, the orthographic projection of the second side L2 onto the base 10 is entirely within the orthographic projection of the pattern enclosed by the outline of the through hole K1 onto the base 10.

[0436] In some embodiments, the edges of both the first electrode 311 and the second electrode 312 include a second side L2, which extends along the first direction X. That is, the edges of both the first electrode 311 and the second electrode 312 along the second direction Y are both second sides L2. At least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10. In other embodiments, the edge of the first electrode 311 along the second direction Y is the second side L2, and at least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10. In still other embodiments, the edge of the second electrode 312 along the second direction Y is the second side L2, and at least a portion of the second side is projected onto the substrate 10 in the orthographic projection of the pattern enclosed by the through-hole K1 within the orthographic projection of the substrate 10.

[0437] In these alternative embodiments, by providing a second side L2, the area of ​​the first electrode 311 and the second electrode 312 blocking the through hole K1 in the thickness direction Z is reduced, so that the through hole can be used as a light-transmitting hole or a clearance hole for other conductive structures. This increases the overlap area between the first electrode 311 and the second electrode 312 and the constant signal line 22, while improving the design flexibility of the through hole K1.

[0438] In some other embodiments, the edge of the third electrode 313 includes a second side L2 that extends along the first direction X, that is, the edge of the third electrode 313 along the second direction Y is the second side L2, thereby reducing the size of the third electrode 313 in the second direction Y.

[0439] Optionally, the second side is a straight edge. In some optional embodiments, such as... Figure 8 and Figure 9 As shown, the first electrode 311, the second electrode 312 and the third electrode 313 are arranged at intervals and extend in the same direction.

[0440] Optionally, such as Figure 9 As shown, the first electrode 311, the second electrode 312, and the third electrode 313 can be spaced apart along the second direction Y, and the first electrode 311, the second electrode 312, and the third electrode 313 all extend along the first direction X. Alternatively, as... Figure 8 As shown, the first electrode 311, the second electrode 312, and the third electrode 313 can be spaced apart along the first direction X, and all three electrodes extend along the second direction Y. Of course, the first electrode 311, the second electrode 312, and the third electrode 313 can also be arranged along other directions.

[0441] The above-described configuration in this embodiment simplifies the arrangement of the pixel electrodes 31, thereby reducing the fabrication difficulty of the pixel electrodes 31 and improving the fabrication yield of the array substrate 100.

[0442] In some alternative embodiments, such as Figure 8 As shown, the extension directions of the constant signal line 22 and the non-constant signal line 21 both intersect the extension directions of the first electrode 311, the second electrode 312, and the third electrode 313. Specifically, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10; and / or, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10.

[0443] Optionally, the extension direction of the constant signal line 22 and the non-constant signal line 21 is the first direction X, and the extension direction of the first electrode 311, the second electrode 312, and the third electrode 313 is the second direction Y. Alternatively, the extension direction of the constant signal line 22 and the non-constant signal line 21 is the second direction Y, and the extension direction of the first electrode 311, the second electrode 312, and the third electrode 313 is the first direction X.

[0444] In some embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10. Furthermore, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10. In other embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same constant signal line 22 onto the substrate 10. In still other embodiments, the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 all overlap with the orthographic projection of the same non-constant signal line 21 onto the substrate 10.

[0445] Optionally, the number of constant signal lines 22 that overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10 can be one or more. For example, the orthographic projections of multiple constant signal lines 22 on the substrate 10 may all overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10.

[0446] Optionally, the number of non-constant signal lines 21 that overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10 can be one or more. For example, the orthographic projections of multiple non-constant signal lines 21 on the substrate 10 may overlap with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 on the substrate 10.

[0447] Through the above-described configuration, this embodiment of the application allows a constant signal line 22 to be arranged below the first electrode 311, the second electrode 312, and the third electrode 313 during the wiring process, thereby increasing the wiring area of ​​the constant signal line 22 and increasing the overlap area between the constant signal line and the pixel electrode 31. At the same time, a non-constant signal line 21 can be arranged below the first electrode 311, the second electrode 312, and the third electrode 313 during the wiring process, which can increase the wiring area of ​​the non-constant signal line 21, increase the design flexibility of the circuit, and improve the applicability of the array substrate 100.

[0448] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along a first direction X and are spaced apart along a second direction Y. Among these, a first constant signal line 221 is provided between any two adjacent pairs of the first non-constant signal line 211 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222.

[0449] For example, the first non-constant signal line 211 corresponding to the first electrode 311, the first non-constant signal line 211 corresponding to the second electrode 312, the first non-constant signal line 211 corresponding to the third electrode 313, and the second constant signal line 222 are arranged sequentially at intervals along the second direction Y. Furthermore, a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the first electrode 311 and the first non-constant signal line 211 corresponding to the second electrode 312, a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the second electrode 312 and the first non-constant signal line 211 corresponding to the third electrode 313, and a first constant signal line 221 is provided between the first non-constant signal line 211 corresponding to the third electrode 313 and the second constant signal line 222.

[0450] In some alternative embodiments, the orthographic projection of the first non-constant signal line 211 corresponding to the first electrode 311 onto the substrate 10 and the orthographic projection of the second constant signal line 222 onto the substrate 10 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the first electrode 311 onto the substrate 10; and / or, the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the orthographic projection of the first non-constant signal line 211 corresponding to the third electrode 313 onto the substrate 10 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the first electrode 311 onto the substrate 10.

[0451] Optionally, the center line of the first electrode 311 along the first direction X can be the center line of the second electrode 312 along the first direction X, or it can be the center line of the third electrode 313 along the first direction X.

[0452] In some optional embodiments, the first constant signal line 221 corresponding to the first electrode 311, the first constant signal line 221 corresponding to the second electrode 312, and the first constant signal line 221 corresponding to the third electrode 313 are sequentially arranged along the second direction Y on the substrate 10. The orthogonal projection of the first constant signal line 221 corresponding to the second electrode 312 on the substrate 10 passes through the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X, and is symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X. The orthogonal projections of the first constant signal line 221 corresponding to the first electrode 311 and the first constant signal line 221 corresponding to the third electrode 313 on the substrate 10 are symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 on the substrate 10 along the first direction X.

[0453] Optionally, the light-emitting units 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313 can form pixel units, and a light-transmitting area can be formed between two adjacent pixel units along the second direction Y. Optionally, the display panel 200 can include a light-transmitting area, and within the light-transmitting area, the light-transmitting area between two adjacent pixels can be used for light transmission.

[0454] In some alternative embodiments, such as Figure 9 As shown, the extension directions of the constant signal line 22 and the non-constant signal line 21 are the same as the extension directions of the first electrode 311, the second electrode 312, and the third electrode 313. Specifically, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10; and / or, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10.

[0455] Optionally, the extension direction of the constant signal line 22 and the non-constant signal line 21 is a first direction X, and the extension direction of the first electrode 311, the second electrode 312 and the third electrode 313 is also a first direction X. Alternatively, the extension direction of the constant signal line 22 and the non-constant signal line 21 is a second direction Y, and the extension direction of the first electrode 311, the second electrode 312 and the third electrode 313 is also a second direction Y.

[0456] For example, multiple constant signal lines 22 are spaced apart along the second direction Y, and the multiple constant signal lines 22 along the second direction Y are sequentially a first constant signal line 22, a second constant signal line 22, and a third constant signal line. A first electrode 311, a second electrode 312, and a third electrode 313 are sequentially arranged along the second direction Y. The orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the second constant signal line 22 onto the substrate 10. Alternatively, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first constant signal line 22 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the second constant signal line 22 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the third constant signal line 22 onto the substrate 10.

[0457] For example, multiple non-constant signal lines 21 are spaced apart along the second direction Y, and the multiple non-constant signal lines 21 are sequentially designated as a first non-constant signal line 21, a second non-constant signal line 21, and a third non-constant signal line along the second direction Y. A first electrode 311, a second electrode 312, and a third electrode 313 are sequentially arranged along the second direction Y. The orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the second non-constant signal line 21 onto the substrate 10. Alternatively, the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 21 onto the substrate 10; the orthographic projection of the second electrode 312 onto the substrate overlaps with the orthographic projection of the second non-constant signal line 21 onto the substrate 10; and the orthographic projection of the third electrode 313 onto the substrate overlaps with the orthographic projection of the third non-constant signal line 21 onto the substrate 10.

[0458] In some embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10; and the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10. In other embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different constant signal lines 22 onto the substrate 10. In still other embodiments, the orthographic projections of at least two of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10 overlap with the orthographic projections of different non-constant signal lines 21 onto the substrate 10.

[0459] This embodiment of the application reduces the size of the pixel electrode 31 in the arrangement direction and increases the size of the pixel electrode 31 in its extension direction through the above arrangement, thereby increasing the overlap area between the pixel electrode 31 and the single constant signal line 22 and the single non-constant signal line 21, reducing the capacitive coupling effect between the pixel electrode 31 and different constant signal lines 22, further reducing the possibility of crosstalk between the non-constant signal line 21 and the pixel electrode 31, improving the display effect of the corresponding light-emitting unit 70, and improving the reliability of the display panel.

[0460] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 and a second constant signal line 222, and the non-constant signal line 21 includes a first non-constant signal line 211. The first constant signal line 221, the second constant signal line 222, and the first non-constant signal line 211 all extend along the first direction X and are spaced apart along the second direction Y. The orthogonal projection of the first constant signal line 221 corresponding to the first electrode 311 or the second electrode 312 onto the substrate 10 passes through the center line of the orthogonal projection of the first electrode 311 or the second electrode 312 onto the substrate 10 along the first direction X, and is symmetrically arranged with respect to the center line of the orthogonal projection of the first electrode 311 or the second electrode 312 onto the substrate 10 along the first direction X.

[0461] For example, the orthographic projection of the first constant signal line 221 corresponding to the first electrode 311 onto the substrate 10 passes through the centerline of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X, and the orthographic projection of the first constant signal line 221 onto the substrate 10 is symmetrically arranged with respect to the centerline of the orthographic projection of the first electrode 311 onto the substrate 10 along the first direction X. And / or, the orthographic projection of the first constant signal line 221 corresponding to the second electrode 312 onto the substrate 10 passes through the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X, and the orthographic projection of the first constant signal line 221 onto the substrate 10 is symmetrically arranged with respect to the centerline of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X.

[0462] In some alternative embodiments, the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate and the orthographic projection of the second constant signal line 222 overlapping with the orthographic projection of the second electrode 312 onto the substrate 10 onto the substrate are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the second electrode 312 onto the substrate 10.

[0463] For example, the orthographic projection of a second constant signal line 222 onto the substrate 10 overlaps with the orthographic projection of the second electrode 312 onto the substrate 10, and the overlapping portion of the orthographic projection of the second constant signal line 222 onto the substrate 10 and the orthographic projection of the second electrode 312 onto the substrate 10 and the first non-constant signal line 211 corresponding to the second electrode 312 are symmetrically arranged along the centerline of the first direction X with respect to the orthographic projection of the second electrode 312 onto the substrate 10.

[0464] In some embodiments, the second constant signal line 222 has a mesh structure. For example, a portion of the multiple second constant signal lines 222 extends along a first direction X, and another portion of the multiple second constant signal lines 222 extends along a second direction Y. The second constant signal line 222 extending along the first direction X is on the same layer as the first constant signal line 221, and the second constant signal line 222 extending along the second direction Y is on a different layer from the second constant signal line 222 extending along the first direction X. A via structure may be provided between the second constant signal line 222 extending along the second direction Y and the second constant signal line 222 extending along the first direction X. The via structure may be located in the overlapping area of ​​the second constant signal line 222 and the pixel electrode 31. The symmetry of the second constant signal line 222 with other signal lines about the center line of the pixel electrode 31 along the first direction X refers to the extension structure of the second constant signal line 222, excluding the via structure. Similarly, the first non-constant signal line 211 and the first constant signal line 221 may also include via structures. The first non-constant signal line 211 and the first constant signal line 221 are symmetrical with other signal lines along the center line of the first direction X with the orthogonal projection of the pixel electrode 31 on the substrate 10, just as the second constant signal line 222 is symmetrical with other signal lines.

[0465] In some alternative embodiments, the distance between the orthographic projection of the first non-constant signal line 211 corresponding to the second electrode 312 onto the substrate 10 and the center line of the orthographic projection of the second electrode 312 onto the substrate 10 along the first direction X is equal to the distance between the orthographic projection of the second constant signal line 222 overlapping with the orthographic projection of the second electrode 312 onto the substrate 10 onto the center line of the second electrode 312 onto the substrate 10 along the first direction X.

[0466] In some optional embodiments, the first constant signal line 221 corresponding to the third electrode 313 includes a first branch, a second branch, and a connecting line. Both the first and second branches extend along a first direction X and are spaced apart along a second direction Y. The first and second branches are connected by the connecting line. The orthographic projection of the third electrode 313 onto the substrate 10 overlaps with the orthographic projection of the first non-constant signal line 211 used to drive the pixel circuit of the first electrode 311 onto the substrate 10. The orthographic projection of the first branch onto the substrate 10 passes through the center line of the orthographic projection of the third electrode 313 onto the substrate 10 along the first direction X and is perpendicular to the third electrode 313. The first non-constant signal line 211 corresponding to the third electrode 313 is symmetrically arranged on the substrate 10 along the center line of the first direction X, with the projection of the first non-constant signal line 211 on the substrate 10 and the projection of the second branch line on the substrate 10 being symmetrically arranged with the projection of the third electrode 313 on the substrate 10 along the center line of the first direction X. The second constant signal line 222 overlapping with the projection of the third electrode 313 on the substrate 10 and the projection of the first non-constant signal line 211 used to drive the pixel circuit of the first electrode 311 on the substrate 10 are symmetrically arranged with the projection of the third electrode 313 on the substrate 10 along the center line of the first direction X.

[0467] Optionally, the orthographic projections of a first branch line, a second branch line, and a connecting line on the substrate 10 all overlap with the orthographic projection of the same third electrode 313 on the substrate 10. Optionally, a first branch line, a second branch line, and a connecting line connecting the first and second branches form a repeating structure. A first constant signal line 221 may include multiple repeating structures. A constant signal line 22 is connected to multiple pixel circuits driving the third electrode 313. The multiple repeating structures and multiple third electrodes 313 are configured in a one-to-one correspondence.

[0468] Optionally, a first branch and a second branch can be connected by one or more connecting lines.

[0469] For example, the orthographic projection of the first branch on the substrate 10 passes through the center line of the orthographic projection of the third electrode 313 on the substrate 10 along the first direction X, and the orthographic projection of the first branch on the substrate 10 is symmetrically arranged with respect to the center line of the orthographic projection of the third electrode 313 on the substrate 10 along the first direction X.

[0470] The above-described configuration in this embodiment facilitates symmetrical arrangement of signal lines on the side of the third electrode 313 facing the substrate 10, improves the flatness of the third electrode 313, and reduces the possibility of color shift in the light-emitting unit 70 corresponding to the third electrode 313 under different viewing angles.

[0471] In some alternative embodiments, the overlapping area of ​​the first electrode 311 and the first constant signal line 221 projected onto the substrate 10 is greater than the overlapping area of ​​the second electrode 312 and the first constant signal line 221 projected onto the substrate 10, and the overlapping area of ​​the second electrode 312 and the first constant signal line 221 projected onto the substrate 10 is greater than the overlapping area of ​​the third electrode 313 and the first constant signal line 221 projected onto the substrate 10.

[0472] In some optional embodiments, the light-emitting units 70 corresponding to the first electrode 311, the second electrode 312, and the third electrode 313 form pixel units, and the arrangement of the constant signal lines 22 and the non-constant signal lines 21 corresponding to the pixel units is the same as the arrangement of the pixel units.

[0473] For example, multiple pixel units are arranged in an array along the first direction X and the second direction Y. The constant signal line 22 corresponding to the first electrode 311, the non-constant signal line 21 corresponding to the first electrode 311, the constant signal line 22 corresponding to the second electrode 312, the non-constant signal line 21 corresponding to the second electrode 312, the constant signal line 22 corresponding to the third electrode 313, and the non-constant signal line 21 corresponding to the third electrode 313 are arranged in an array as a sub-unit along the first direction X and the second direction Y.

[0474] Figure 10 This is a partially enlarged structural schematic diagram of another array substrate 100 provided in the embodiments of this application.

[0475] In some alternative embodiments, such as Figure 10 As shown, the first electrode 311 and the second electrode 312 are spaced apart along the first direction X, and the third electrode 313 is located on the same side of the adjacent first electrode 311 and the second electrode 312 along the second direction Y. The third electrode 313 is spaced apart from the adjacent first electrode 311 and the second electrode 312 along the second direction Y. The first direction X, the second direction and the thickness direction Z of the array substrate 100 intersect each other.

[0476] For example, the first electrode 311, the second electrode 312 and the third electrode 313 are arranged in a triangular pattern.

[0477] Optionally, the area of ​​the third electrode may be greater than or equal to the sum of the areas of the first electrode 311 and the second electrode 312.

[0478] The embodiments of this application, through the above-described settings, facilitate the increase in the arrangement of the corresponding light-emitting units 70, improve the design flexibility of the light-emitting units, and broaden the applicability of the display panel.

[0479] In some optional embodiments, the constant signal line 22 includes a first constant signal line 221 extending along a first direction X; wherein the overlapping area of ​​the orthographic projection of the first electrode 311 and the first constant signal line 221 on the substrate 10 is smaller than the overlapping area of ​​the orthographic projection of the second electrode 312 and the first constant signal line 221 on the substrate 10, and the overlapping area of ​​the orthographic projection of the second electrode 312 and the first constant signal line 221 on the substrate 10 is smaller than the overlapping area of ​​the orthographic projection of the third electrode 313 and the first constant signal line 221 on the substrate 10.

[0480] Optionally, the orthographic projection of the first electrode 311 onto the substrate 10 may overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the first electrode 311 onto the substrate 10. The orthographic projection of the first electrode 311 onto the substrate 10 may also overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the second electrode 312 onto the substrate 10. It is understood that when the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with both the first constant signal line 221 driving the pixel circuit of the first electrode 311 and the first constant signal line 221 driving the pixel circuit of the second electrode 312, the sum of their overlapping areas is the overlapping area of ​​the orthographic projections of the first electrode 311 and the first constant signal line 221 onto the substrate 10.

[0481] Optionally, the orthographic projection of the second electrode 312 onto the substrate 10 may overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the second electrode 312 onto the substrate 10. The orthographic projection of the second electrode 312 onto the substrate 10 may also overlap with the orthographic projection of the first constant signal line 221 driving the pixel circuit of the first electrode 311 onto the substrate 10. It is understood that when the orthographic projection of the first electrode 311 onto the substrate 10 overlaps with both the first constant signal line 221 driving the pixel circuit of the first electrode 311 and the first constant signal line 221 driving the pixel circuit of the second electrode 312, the sum of their overlapping areas is the overlapping area of ​​the orthographic projections of the second electrode 312 and the first constant signal line 221 onto the substrate 10.

[0482] In some alternative embodiments, the first constant signal line 221 includes a surface signal portion 221a, the area of ​​which is equal to ...

[0483] It is understandable that the area of ​​the surface signal section 221a corresponding to the second electrode 312 is smaller than the area of ​​the surface signal section 221a corresponding to the third electrode 313.

[0484] In some alternative embodiments, the orthographic projection of a portion of the surface signal portion 221a corresponding to the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the first electrode 311 onto the substrate 10, and the orthographic projection of another portion of the surface signal portion 221a corresponding to the first electrode 311 onto the substrate 10 overlaps with the orthographic projection of the second electrode 312 onto the substrate 10.

[0485] In some alternative embodiments, the orthographic projection of the surface signal portion 221a corresponding to the second electrode 312 onto the substrate 10 overlaps with the orthographic projections of the first electrode 311, the second electrode 312, and the third electrode 313 onto the substrate 10.

[0486] For example, a surface signal unit 221a includes three regions, one of which has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the first electrode 311 on the substrate 10, one of which has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the second electrode 312 on the substrate 10, and the last region has an orthographic projection on the substrate 10 that overlaps with the orthographic projection of the third electrode 313 on the substrate 10.

[0487] In some alternative embodiments, the surface signal portions 221a corresponding to the same type of pixel electrode 31 in adjacent pixel electrodes 31 are connected to form a whole surface structure.

[0488] For example, a surface signal portion 221a corresponding to a third electrode 313 is connected to a surface signal portion 221a corresponding to an adjacent third electrode 313 to form a full-surface structure.

[0489] Optionally, a third electrode 313 may correspond to a plurality of surface signal portions 221a. For example, a third electrode 313 may correspond to two surface signal portions 221a. The area of ​​one of the surface signal portions 221a corresponding to the third electrode 313 may be larger than the area of ​​the surface signal portion 221a corresponding to the first electrode 311. The area of ​​the other surface signal portion 221a corresponding to the third electrode 313 may be equal to the area of ​​the surface signal portion 221a used to drive the pixel circuit of the second electrode 312 that overlaps with the orthographic projection of the first electrode 311 on the substrate 10. And / or, the area of ​​one of the two surface signal portions 221a corresponding to the third electrode 313 may be greater than the area of ​​the surface signal portion 221a corresponding to the second electrode 312, and the area of ​​the other surface signal portion 221a corresponding to the third electrode 313 may be equal to the area of ​​the surface signal portion 221a used to drive the pixel circuit of the first electrode 311 that overlaps with the orthographic projection of the second electrode 312 on the substrate 10.

[0490] Figure 15 This is a cross-sectional structural diagram of a display panel provided in an embodiment of this application.

[0491] Please see Figure 15 An embodiment of the third aspect of this application also provides a display panel, including an array substrate 100 and a light-emitting layer as described in any of the above embodiments. The light-emitting layer is located on one side of the array substrate 100, and includes light-emitting units 70. The orthographic projection of the light-emitting units onto the substrate 10 at least partially overlaps with the orthographic projection of the pixel electrode 31 onto the substrate.

[0492] Since the display panel provided in the third aspect of this application includes the array substrate 100 of any of the above embodiments, the display panel provided in the third aspect of this application has the beneficial effects of the array substrate 100 of any of the above embodiments, which will not be repeated here.

[0493] In some alternative embodiments, such as Figure 15 As shown, the display panel also includes an isolation structure 60, which is located on one side of the array substrate 100. The isolation structure encloses and forms an isolation opening 63, and at least a portion of the light-emitting unit 70 is located within the isolation opening.

[0494] The isolation structure 60 is a structure in the display panel that can separate different light-emitting units 70.

[0495] Optionally, other film layers may be disposed between the isolation structure 60 and the first electrode layer 30, with the isolation structure located on the side of the other film layers facing away from the first electrode layer 30. Optionally, the other film layers include a pixel definition layer 90. Optionally, the display panel also includes a second electrode layer 80, located on the side of the light-emitting unit 70 facing away from the first electrode layer 30. The second electrode layer 312 may include multiple second electrodes, each corresponding to a light-emitting unit 70.

[0496] In some alternative embodiments, such as Figures 2 to 4 As shown, the isolation structure 60 includes a first isolation portion 61 and a second isolation portion 62 located on the side of the first isolation portion 61 away from the array substrate 100. The orthographic projection of the side of the first isolation portion away from the substrate onto the array substrate 100 is located within the orthographic projection of the second isolation portion 62 onto the array substrate 100.

[0497] This design helps to prevent the luminescent material from extending along the sidewall of the first isolation section 61 to the sidewall of the second isolation section 62 during the fabrication of the luminescent functional layer. This allows for the fabrication and separation of the luminescent units 70 within different isolation openings 63 without the need for a fine metal mask.

[0498] The specific structural dimensions of the first isolation portion 61 and the second isolation portion 62 are not limited in the embodiments of this application. Exemplarily, the longitudinal section (perpendicular to the substrate) of the isolation structure 60 can be a T-shaped structure.

[0499] Compared to the second isolation portion 62, the first isolation portion 61 has a smaller orthographic projection size on the substrate, and normally, the orthographic projection of the first isolation portion 61 on the substrate 10 is located at the center of the orthographic projection of the isolation structure 60 on the substrate.

[0500] In some embodiments, such as Figure 15 As shown, at least one of the first isolation portion 61 and the second isolation portion 62 is disposed on the substrate 10 in a projection that overlaps with the projection portion of the pixel electrode 31 on the substrate.

[0501] In some embodiments, the orthographic projection of the first isolation portion 61 onto the substrate 10 and the projection of the second isolation portion 62 onto the substrate 10 both overlap with the projection portion of the pixel electrode 31 onto the substrate. In other embodiments, the orthographic projection of the first isolation portion 61 onto the substrate 10 overlaps with the projection portion of the pixel electrode 31 onto the substrate. In still other embodiments, the orthographic projection of the second isolation portion 62 onto the substrate 10 overlaps with the projection portion of the pixel electrode 31 onto the substrate.

[0502] Figure 16 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0503] In some embodiments, such as Figure 16 As shown, the isolation structure 60 encloses and forms the first opening 64. Along the direction in which the isolation opening 63 and the first opening are arranged side by side, the orthographic projection of the pixel electrode 31 on the substrate 10 exceeds the orthographic projection of the isolation structure 60 on the substrate 10, and overlaps with the orthographic projection of the outline of the first opening 64 on the substrate.

[0504] Optionally, the first opening 64 can be a light-transmitting opening, which can improve the light transmittance of the display panel.

[0505] Optionally, the isolation opening 63 and the first opening 64 are spaced apart.

[0506] The orthographic projection of the pixel electrode 31 onto the substrate 10 exceeds the orthographic projection of the isolation structure 60 onto the substrate 10. In other words, the orthographic projection of a portion of the pixel electrode 31 onto the substrate 10 overlaps with the orthographic projection of the isolation opening 63 onto the substrate 10, and the orthographic projection of another portion of the pixel electrode 31 onto the substrate 10 overlaps with the orthographic projection of the first opening 64 onto the substrate.

[0507] In this embodiment, the isolation structure 60 is electrically connected to the power supply voltage (e.g., cathode) in the display panel through the above-described configuration, so that the isolation structure 60 has a constant signal, increasing the overlap area between the pixel electrode 31 and the isolation structure, thereby increasing the design flexibility of the pixel electrode and improving the applicability of the display panel.

[0508] Figure 17 This is a cross-sectional structural diagram of another display panel provided in an embodiment of this application.

[0509] like Figure 17 As shown, in some optional embodiments, the isolation structure 60 further includes a third isolation portion 65 located on the side of the first isolation portion 61 facing the array substrate 100. The orthographic projection of the first isolation portion onto the substrate 10 lies within the orthographic projection of the third isolation portion 65 onto the substrate.

[0510] The third isolation section is a structure in the isolation structure 60 located on the side of the first isolation section 61 facing the array substrate. The orthographic projection of the first isolation section on the substrate 10 is located within the orthographic projection of the third isolation section 65 on the substrate. That is, in the direction parallel to the plane where the substrate is located, the third isolation section 65 can be partially extended beyond the first isolation section 61.

[0511] For example, the projected area of ​​the first isolation portion on the substrate 10 is smaller than the projected area of ​​the third isolation portion 65 on the substrate. For example, the longitudinal section (perpendicular to the array substrate 100) of the isolation structure 60 can be I-shaped.

[0512] In some optional embodiments, the second electrode layer 80 is electrically connected to the third isolation portion 65, for example, through electrical contact. Due to the limitations of the shape and structure of the first isolation portion 61, the second electrode layer 80 may have poor contact with the sidewall of the first isolation portion. However, by adding the third isolation portion 65, the second electrode layer 80 can more easily cover part of the structure in the third isolation portion. That is, the orthographic projection of the second electrode layer 80 on the substrate 10 can overlap with the orthographic projection of the third isolation portion 65 on the substrate, thereby satisfying the electrical connection requirements between the second electrode layer 80 and the isolation structure 60. The third isolation portion 65 may include a conductive material. Optionally, the second electrode layer 80 includes a plurality of second pixel electrodes 31, at least a portion of which is located within the isolation opening 63. Optionally, the second pixel electrodes 31 are disposed opposite to the pixel electrodes in the first electrode layer 30.

[0513] In some alternative embodiments, the first isolation portion 61 comprises metal, and / or the second isolation portion 62 comprises metal, and / or the third isolation portion 65 comprises metal. Further, the first isolation portion 61 comprises aluminum, and / or the second isolation portion 62 comprises titanium, and / or the third isolation portion 65 comprises molybdenum.

[0514] In some alternative embodiments, the orthographic projection of the pixel electrode 31 onto the substrate 10 and the orthographic projection of the third isolation portion 65 onto the substrate are at least partially overlapped.
