Description

Technical Field

[0001] This application relates to the field of display panel technology, and more particularly to a display panel and a display device. Background Technology

[0002] With the continuous development of technology, users' demands for display devices such as mobile phones and tablets are becoming more and more diversified. For example, ultra-narrow bezel or borderless displays are increasingly favored by customers.

[0003] Full-screen borderless displays offer users a better viewing experience, but due to their unique borderless technology, their manufacturing process requires cutting, edge grinding, and corresponding film application. These processes generate static electricity, which can damage the substrate and consequently reduce the display's yield. Summary of the Invention

[0004] This application provides a display panel and a display device. By setting an electrostatic discharge structure in the display area and electrically connecting the electrostatic discharge structure to the first pixel circuit or the first light-emitting element, the electrostatic discharge structure releases static electricity in the first pixel circuit and / or the first light-emitting element, thereby eliminating or reducing damage to the display panel caused by static electricity and ensuring the structural and performance stability of the display panel.

[0005] In a first aspect, embodiments of this application provide a display panel, including a display area and a plurality of light-emitting elements and a plurality of pixel circuits located in the display area; The plurality of light-emitting elements include a first light-emitting element, the plurality of pixel circuits include a first pixel circuit, the first pixel circuit is electrically connected to the first light-emitting element, and the first light-emitting element is located on the side of the first pixel circuit near the edge of the display panel; The display panel further includes an electrostatic discharge structure located in the display area, and the electrostatic discharge structure is electrically connected to the first pixel circuit. Alternatively, the first pixel circuit is electrically connected to the first light-emitting element through a first circuit connection structure, and the first circuit connection structure is electrically connected to the electrostatic discharge structure.

[0006] Secondly, embodiments of this application provide a display device including the display panel described in the first aspect.

[0007] In summary, the display panel provided in this application, by positioning the first light-emitting element on the side of the first pixel circuit near the edge of the display panel, avoids the appearance of undisplayed areas at the edge of the display panel due to the first pixel circuit being located at the edge, thus ensuring an ultra-narrow bezel or borderless display panel design and improving the screen-to-body ratio. Furthermore, the display panel also includes an electrostatic discharge structure disposed in the display area. The electrostatic discharge structure is electrically connected to the first pixel circuit, or, alternatively, the electrostatic discharge structure is electrically connected to the first light-emitting element through a first circuit connection structure. Thus, by adding an electrostatic discharge structure to the display area, static electricity in the first pixel circuit and / or the first light-emitting element is released, eliminating or reducing damage to the display panel caused by static electricity and ensuring the structural and performance stability of the display panel.

Detailed Implementation

[0011] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0015] Figure 1 This is a schematic diagram of the structure of a display panel provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shown is an enlarged view of area a in the display panel, combined with... Figure 1 As shown, the display panel provided in this application embodiment includes a display area AA with a plurality of light-emitting elements 10 and a plurality of pixel circuits 20 located in the display area AA; the plurality of light-emitting elements 10 include a first light-emitting element 101, the plurality of pixel circuits 20 include a first pixel circuit 201, the first pixel circuit 201 is electrically connected to the first light-emitting element 101, and the first light-emitting element 101 is located on the side of the first pixel circuit 201 near the edge of the display panel; the display panel also includes an electrostatic discharge structure 30 located in the display area AA, the electrostatic discharge structure 30 is electrically connected to the first pixel circuit 201; or, the first pixel circuit 201 is electrically connected to the first light-emitting element 101 through a first circuit connection structure 40, and the first circuit connection structure 40 is electrically connected to the electrostatic discharge structure 30.

[0016] like Figure 1As shown, the display panel includes a display area AA and multiple light-emitting elements 10 and multiple pixel circuits 20 located in the display area AA. The multiple pixel circuits 20 and the multiple light-emitting elements 10 are electrically connected to each other. The pixel circuits 20 are used to transmit driving current to the light-emitting elements 10 under the action of signals from driving signal lines (such as scan signal lines, data signal lines, power signal lines, etc.) on the display panel, so as to drive the light-emitting elements 10 to emit light. The multiple light-emitting elements 10 may include light-emitting elements of different colors, such as one or more of red light-emitting elements, green light-reflecting elements, blue light-emitting elements, and white light-emitting elements, to realize the display panel's solid color display or color display. Furthermore, the light-emitting elements 10 may include miniature light-emitting diodes (such as Micro-LED, Mini-LED) to achieve higher brightness and a longer lifespan, which can meet the display requirements of outdoor or high-brightness environments. Alternatively, the light-emitting elements 10 may also be organic light-emitting diodes (OLED) or other types of light-emitting devices, which are not specifically limited in this embodiment of the invention. Furthermore, when the light-emitting element 10 is a miniature light-emitting diode, the display panel also includes an anode pad and a cathode pad. The anode of the miniature light-emitting element is electrically connected to the pixel circuit through the anode pad, and the cathode of the miniature light-emitting element is electrically connected to the cathode signal line through the cathode pad. Further, the pixel circuit 20 can be, for example, a "2T1C", "7T1C", or "8T1C" structure; or, the pixel circuit includes an amplitude adjustment module and a pulse width adjustment module. The amplitude adjustment module is used to provide a driving current to the light-emitting element 10 and control the luminous efficiency of the light-emitting element 10 by adjusting the amplitude of the driving current; the pulse width adjustment module is used to control the duration for which the amplitude adjustment module provides the driving current to the light-emitting element 10, thereby controlling the luminous duration of the light-emitting element 10. By controlling the luminous duration of the light-emitting element 10 (i.e., adjusting the luminous duty cycle of the light-emitting element 10), the luminous brightness of the light-emitting element 10 can be controlled.

[0017] Continue to refer to Figure 1 and Figure 2The light-emitting element 10 includes a first light-emitting element 101, and the pixel circuit 20 includes a first pixel circuit 201. The first light-emitting element 101 and the first pixel circuit 201 are electrically connected, and the first light-emitting element 101 is located on the side of the first pixel circuit 201 closer to the edge of the display panel. This arrangement ensures that the edge of the display panel can emit light and display light, while preventing undisplayed areas from appearing at the edge of the display panel due to the first pixel circuit 201 being located there. This ensures an ultra-narrow bezel or bezel-less display panel design, improving the screen-to-body ratio. Furthermore, the display panel may also include a first circuit connection structure 40, which electrically connects the first light-emitting element 101 and the first pixel circuit 201. This allows the first light-emitting element 101 and the first pixel circuit 201, which are spaced apart in a first direction (as shown in the X direction in the figure, which will be used as an example in the following explanation), to be electrically connected, ensuring that the first pixel circuit 201 can drive the first light-emitting element 101 to emit light and display normally.

[0018] Furthermore, the inventors discovered that due to the unique characteristics of narrow or borderless display panels, the manufacturing process requires cutting, edge grinding, and corresponding film application. These processes generate static electricity that can damage the display panel itself, leading to a loss of yield. Simultaneously, due to the extremely narrow or borderless design, the first light-emitting element 101 is located near the edge of the display panel, with its electrodes exposed. This is particularly true for the anode pads in the micro-LEDs, where the exposed area at the edge of the display panel is relatively large. Consequently, static charge generated during these processes can easily enter the first light-emitting element 101 through the edge electrodes and further enter the first pixel circuit 201 via the first circuit connection structure 40, thus affecting the normal operation of both the first light-emitting element 101 and the first pixel circuit 201.

[0019] Based on this, the embodiments of this application creatively provide an electrostatic discharge structure 30 in the display area. The electrostatic discharge structure 30 is electrically connected to the first pixel circuit 201, or the electrostatic discharge structure 30 is electrically connected to the first light-emitting element 101 and the first pixel circuit 201 through the first circuit connection structure 40. In this way, the electrostatic discharge structure can release the static electricity in the first pixel circuit 201 and / or the first light-emitting element 101, eliminate or reduce the damage to the display panel caused by static electricity, and ensure the structural and performance stability of the display panel.

[0020] It should be noted that continued reference is necessary. Figure 1As shown, the light-emitting element 10 may further include a second light-emitting element 102, and the pixel circuit 20 may further include a second pixel circuit 202. The second light-emitting element 102 is located on the side of the first light-emitting element 101 away from the edge of the display panel, and the second pixel circuit 202 is located on the side of the first pixel circuit 201 away from the edge of the display panel. The second light-emitting element 102 and the second pixel circuit 202 are electrically connected, and the second pixel circuit 202 is used to drive the second light-emitting element 102 to emit light for display. It is understood that, along the thickness direction of the display panel, the second light-emitting element 102 and the second pixel circuit 202 may at least partially overlap (e.g., ...). Figure 1 As shown), the anode in the second light-emitting element 102 can be directly electrically connected to the second pixel circuit 202. In this case, the electrical connection between the second light-emitting element 102 and the second pixel circuit 202 can be achieved without setting a circuit connection structure. Alternatively, along the thickness direction of the display panel, the second light-emitting element 102 and the second pixel circuit 202 do not overlap. The electrical connection between the second light-emitting element 102 and the second pixel circuit 202 also requires setting a circuit connection structure. In this case, the second light-emitting element 102 is the same as the first light-emitting element 101 mentioned above, and the second pixel circuit 202 is the same as the first pixel circuit 201 mentioned above. In this case, the first light-emitting element 101 includes multiple light-emitting elements disposed on the outermost ring of the display panel, or it may include multiple light-emitting elements disposed on the second outermost ring of the display panel. The specific number of the first light-emitting elements 101 is not limited in this embodiment. In other words, the display panel includes an array substrate and light-emitting elements. The array substrate is provided with an array of pixel circuits. After the large-area array substrate is cut into the required small-area array substrate, the light-emitting elements are then bound on the array substrate. That is, the array substrate needs to be cut, and then the light-emitting elements are bound. To avoid damaging the pixel circuits near the edges during cutting, the pixel circuits at the edge of the array substrate can be moved away from the edge by compressing the spacing between them. However, to ensure that the edges of the display panel also have a display effect, light-emitting elements need to be placed at the edges of the display panel. This results in a significant misalignment between the light-emitting elements in the edge area and their corresponding electrically connected pixel circuits, requiring electrical connections via "flying wires," which are the first circuit connection structure. Furthermore, considering the degree of misalignment between the light-emitting elements in the edge area and their corresponding electrically connected pixel circuits, as described above, at least the outermost ring of light-emitting elements needs to be electrically connected to their corresponding pixel circuits via the first circuit connection structure.

[0021] It should also be noted that, Figure 2The illustrated structure uses a miniature light-emitting diode (LED) as an example for the first light-emitting element 101. It can be understood that the first light-emitting element 101 includes an anode, a cathode, and a light-emitting layer. The anode is electrically connected to the anode pad and is used to receive the display driving signal provided by the first pixel circuit 201. The position of the anode pad corresponds to the position of the anode in the first light-emitting element 101 and is generally the same as the placement position of the first light-emitting element 101. Figure 2 The first light-emitting element 101 is represented by an anode pad.

[0022] In summary, the display panel provided in this application, by positioning the first light-emitting element on the side of the first pixel circuit near the edge of the display panel, avoids undisplayed areas at the edge of the display panel caused by the first pixel circuit being located at the edge, ensuring an ultra-narrow bezel or bezel-less display panel design and improving the screen-to-body ratio. Furthermore, the display panel also includes an electrostatic discharge structure disposed in the display area. The electrostatic discharge structure is electrically connected to the first pixel circuit, or, alternatively, the electrostatic discharge structure is electrically connected to the first light-emitting element through a first circuit connection structure. Thus, by adding an electrostatic discharge structure to the display area, static electricity in the first pixel circuit and / or the first light-emitting element is released, eliminating or reducing damage to the display panel caused by static electricity, and ensuring the structural and performance stability of the display panel.

[0023] Optional, continue to refer to Figure 2 As shown, the first circuit connection structure 40 is electrically connected to the electrostatic discharge structure 30 through the second circuit connection structure 50; the first circuit connection structure 40 and the second circuit connection structure 50 are arranged in different layers.

[0024] like Figure 2 As shown, the display panel may further include a second circuit connection structure 50, which is electrically connected to the first circuit connection structure 40 and the electrostatic discharge structure 30, respectively. Thus, the first light-emitting element 101 is electrically connected to the electrostatic discharge structure 30 through the first circuit connection structure 40 and the second circuit connection structure 50. If electrostatic charge accumulates in the first light-emitting element 101, the accumulated charge can be released in the electrostatic discharge structure 30 through the first circuit connection structure 40 and the second circuit connection structure 50, preventing interference from the electrostatic charge to the first light-emitting element 101.

[0025] Furthermore, the first circuit connection structure 40 and the second circuit connection structure 50 can be disposed in different film layers, that is, the first circuit connection structure 40 and the second circuit connection structure 50 are disposed in different layers. This simplifies the setting requirements of the first circuit connection structure 40 and the second circuit connection structure 50, making it easier to find the setting space of the first circuit connection structure 40 and the second circuit connection structure 50 in different film layers, ensuring that there is enough space in the display area to set the first circuit connection structure 40 and the second circuit connection structure 50, and ultimately achieving the purpose of electrostatic discharge.

[0026] Optional, continue to refer to Figure 2 As shown, the electrostatic discharge structure 30 includes a discharge connection substructure 301 and an electrostatic discharge substructure 302; the discharge connection substructure 301 is electrically connected to the second circuit connection structure 50 and is correspondingly arranged with the electrostatic discharge substructure 302.

[0027] Specifically, such as Figure 2 As shown, the electrostatic discharge structure 30 includes a discharge connection substructure 301 and an electrostatic discharge substructure 302. The discharge connection substructure 301 can be understood as the connection between the electrostatic discharge substructure 302 and the second circuit connection structure 50, and is also the part for transmitting electrostatic charge. The electrostatic charge is transmitted to the electrostatic discharge substructure 302 after passing through the first light-emitting element 101, the first circuit connection structure 40, the second circuit connection structure 50 and the discharge connection substructure 301 in sequence, so that at least part of the electrostatic charge is released in the electrostatic discharge substructure 302.

[0028] Optional, continue to refer to Figure 2As shown, the display panel also includes a first light-emitting element group 11, a first pixel circuit group 12, a first circuit connection structure group 13, a second circuit connection structure group 14, and a release connection substructure group 15; the first light-emitting element group 11 includes a plurality of first light-emitting elements 101, the first pixel circuit group 12 includes a plurality of first pixel circuits 201, the first circuit connection structure group 13 includes a plurality of first circuit connection structures 40, the second circuit connection structure 14 includes a plurality of second circuit connection structures 50, and the release connection substructure group 15 includes a plurality of release connection substructures 301; the plurality of first light-emitting elements 101 in the same first light-emitting element group 11 are arranged along a first direction X, and the plurality of first pixel circuits 201 in the same first pixel circuit group 12 are arranged along a first direction X; the same first circuit connection... Multiple first circuit connection structures 40 in structure group 13 extend along the first direction X and are arranged along the second direction (Y direction as shown in the figure, the second direction Y will be used as an example for the following description), and are electrically connected to multiple first light-emitting elements 101 in the same first light-emitting element group 11; the second direction Y intersects with the first direction X; multiple second circuit connection structures 50 in the same second circuit connection structure group 14 extend along the second direction Y and are arranged along the first direction X, and are electrically connected to multiple first circuit connection structures 40 in the same first circuit connection structure group 13; multiple release connection substructures 301 in the same release connection substructure group 15 extend along the first direction X and are arranged along the second direction Y, and are electrically connected to multiple second circuit connection structures 50 in the same second circuit connection structure group 14.

[0029] like Figure 2 As shown, the first light-emitting element group 11 includes multiple first light-emitting elements 101. The multiple first light-emitting elements 101 in the same first light-emitting element group 11 can be red light-emitting elements, green light-emitting elements, and blue light-emitting elements, respectively. That is, the first light-emitting element group 11 can be the smallest light-emitting unit to achieve white light emission. The multiple first light-emitting elements 101 in the same first light-emitting element group 11 are arranged sequentially in the first direction X. Correspondingly, the multiple first pixel circuits 201 in the same first pixel circuit group 12 are arranged along the first direction X. This facilitates the corresponding electrical connection between the multiple first light-emitting elements 101 in the same first light-emitting element group 11 and the multiple first pixel circuits 201 in the same first pixel circuit group 12. Figure 2Based on the indicated orientation, the leftmost first light-emitting element 101 in the same first light-emitting element group 11 can be electrically connected to the leftmost first pixel circuit 201 in the first pixel circuit group 12 via the first circuit connection structure 40; the middle first light-emitting element 101 in the same first light-emitting element group 11 can be electrically connected to the middle first pixel circuit 201 in the first pixel circuit group 12 via the first circuit connection structure 40; and the rightmost first light-emitting element 101 in the same first light-emitting element group 11 can be electrically connected to the rightmost first pixel circuit 201 in the first pixel circuit group 12 via the first circuit connection structure 40. This ensures that the extension lengths of different first circuit connection structures 40 are the same or similar, and that the loss of the display driving signal in different first circuit connection structures 40 is the same or similar, thus ensuring that the luminous effect of multiple first light-emitting elements 101 in the same light-emitting element group 11 is the same or similar.

[0030] Furthermore, the plurality of first circuit connection structures 40 in the same first circuit connection structure group 13 extend along the first direction X and are arranged along the second direction Y, thereby realizing the corresponding electrical connection between the plurality of first light-emitting elements 101 in the same first light-emitting element group 11 and the plurality of first pixel circuits 201 in the same first pixel circuit group 12. The plurality of second circuit connection structures 50 in the same second circuit connection structure group 14 extend along the second direction Y and are arranged along the first direction X, and the plurality of release connection substructures 301 in the same release connection substructure group 15 extend along the first direction X and are arranged along the second direction Y. The plurality of second circuit connection structures 50 in the same second circuit connection structure group 14 realize the corresponding electrical connection between the plurality of first circuit connection structures 40 in the same first circuit connection structure group 13 and the plurality of release connection substructures 301 in the same release connection substructure group 15. By rationally setting the wiring methods of multiple first circuit connection structures 40 in the same first circuit connection structure group 13, multiple second circuit connection structures 50 in the same second circuit connection structure group 14, and multiple release connection substructures 301 in the same release connection substructure group 15, the wiring of the display panel is kept neat and orderly while achieving the corresponding electrical connections, thus reducing the difficulty of wiring.

[0031] It should be noted that, in the embodiments of this application, the multiple first circuit connection structures 40 in the same first circuit connection structure group 13 extending along the first direction X and arranged along the second direction Y means that the multiple first circuit connection structures 40 in the same first circuit connection structure group 13 generally extend along the first direction X and are arranged along the second direction Y, rather than limiting any small segment of the first circuit connection structure 40 to extend along the first direction X. The first circuit connection structure 40 may have a portion extending along the second direction Y, but this does not affect the overall distribution of the multiple first circuit connection structures 40. Similarly, the multiple second circuit connection structures 50 in the same second circuit connection structure group 14 extending along the second direction Y and arranged along the first direction X means that the multiple second circuit connection structures 50 in the same second circuit connection structure group 14 generally extend along the second direction Y and are arranged along the first direction X, rather than limiting any small segment of the second circuit connection structure 50 to extend along the second direction Y. The second circuit connection structure 50 may have a portion extending along the first direction X, but this does not affect the overall distribution of the multiple second circuit connection structures 50. Similarly, multiple release connection substructures 301 in the same release connection substructure group 15 extend along the first direction X and are arranged along the second direction Y. This means that multiple release connection substructures 301 in the same release connection substructure group 15 generally extend along the first direction X and are arranged along the second direction Y, rather than limiting any small segment of the release connection substructure 301 to extend along the first direction X. The release connection substructure 301 may have a part that extends along the second direction Y, but this does not affect the overall distribution of the multiple release connection substructures 301.

[0032] It should also be noted that, such as Figure 2 As shown, along the second direction Y, multiple first circuit connection structures 40 in the first circuit connection structure group 13, multiple second circuit connection structures 50 in the same second circuit connection structure group 14, and multiple release connection substructures 301 in the same release connection substructure group 15 are all disposed on one side of the same first pixel circuit group 12. Therefore, in order to ensure that the multiple first circuit connection structures 40, multiple second circuit connection structures 50, and multiple release connection substructures 301 have sufficient placement space, the first pixel circuit 201 can be configured to have a certain degree of compression in the second direction Y, or in other words, the spacing between two adjacent first pixel circuits 201 along the second direction Y is compressed to a certain extent in the second direction Y. Furthermore, the compression of the first pixel circuit 201 in the first direction Y can be achieved by reducing the size and spacing of components (such as transistors and / or capacitors), etc., and the embodiments do not limit this.

[0033] Continue to refer to Figure 2As shown, along the first direction X, the electrostatic discharge substructure 302 is disposed between the first light-emitting element group 11 and the first pixel circuit group 12, thus realizing the design concept of placing the electrostatic discharge substructure 302 in the display area AA. Furthermore, as shown in Figure 2, multiple signal lines 70 are also provided in the display area. The signal lines 70 can be electrically connected to the pixel circuit 20 or used as transmission lines for other signals. Figure 2 As shown, the signal line 70 can be positioned between the first light-emitting element group 11 and the first pixel circuit group 12 in the first direction X, or the end of the signal line 70 can terminate between the first light-emitting element group 11 and the first pixel circuit group 12. That is, along the first direction X, there is a large space between the first light-emitting element group 11 and the first pixel circuit group 12, which can be used to position the signal line 70 and the electrostatic discharge substructure 302. Thus, positioning the electrostatic discharge substructure 302 between the first light-emitting element group 11 and the first pixel circuit group 12 along the first direction X does not occupy additional space for other structures and does not affect the normal structural arrangement of the display panel. Furthermore, positioning the electrostatic discharge substructure 302 between the first light-emitting element group 11 and the first pixel circuit group 12 along the first direction X effectively draws the electrostatic charge from the display area AA back to a position near the edge of the display area AA, further reducing the interference of electrostatic charge on the pixel circuits and / or light-emitting elements in the central area of ​​the display area AA, ensuring the overall structural and performance stability of the display panel.

[0034] And continue to refer to Figure 1 and Figure 2 As shown, the display area includes a first sub-display area AA1 and a second sub-display area AA2. Along the first direction, the first sub-display area AA1 is located on the side of the second sub-display area AA2 near the edge of the display area. The first light-emitting element 101 is disposed in the first sub-display area AA1, and the electrostatic discharge structure 30 is disposed in the first sub-display area AA1.

[0035] like Figure 1 and Figure 2As shown, the display area includes a first sub-display area AA1 and a second sub-display area AA2. Along the first direction X, the first sub-display area AA1 is located on the side of the second sub-display area AA2 near the edge of the display area. That is, the first sub-display area AA1 can be an edge sub-display area in the display panel, or the first display area AA1 includes the cutting boundary line of the display panel. The second sub-display area AA2 can be a central sub-display area of ​​the display panel, and the second sub-display area AA2 can be at least partially surrounded by the first sub-display area AA1. A first light-emitting element 101 is disposed in the first sub-display area AA1, and an electrostatic discharge substructure 30 is disposed in the first sub-display area AA1. That is, an electrostatic discharge substructure 30 is disposed in the area where the first light-emitting element 101 needs to be electrically connected through the first circuit connection structure 40, so as to release the electrostatic charge introduced into the display area AA through the first circuit connection structure 40, and ensure that the light-emitting element and circuit structure in the display area AA are protected from interference by electrostatic charge.

[0036] Optional, Figure 3 yes Figure 1 Another enlarged structural diagram of area a in the display panel shown. Figure 4 yes Figure 1 The diagram shows another enlarged structural representation of area a in the display panel shown, combined with... Figure 3 and Figure 4 As shown, the display panel also includes a third circuit connection structure 60, which is electrically connected to the first pixel circuit 201 and the first circuit connection structure 40, and is also electrically connected to the second circuit connection structure 50; the resistance of the third circuit connection structure 60 is greater than the resistance of the second circuit connection structure 50.

[0037] like Figure 3 As shown, the display panel also includes a third circuit connection structure 60, which is electrically connected to the first pixel circuit 201 and the first circuit connection structure 40. Thus, the display signal provided by the first pixel circuit 201 is output to the first light-emitting element 101 through the third circuit connection structure 60 and the first circuit connection structure 40, thereby achieving the effect of the first pixel circuit 201 driving the first light-emitting element 101 to emit light and display.

[0038] Furthermore, due to the configuration of the first circuit connection structure 40 and the third circuit connection structure 60, static electricity generated during the manufacturing process of the display panel, such as cutting, edge grinding, and corresponding film application, is transmitted to the first pixel circuit 201 via the first light-emitting element 101, the first circuit connection structure 40, and the third circuit connection structure 60, potentially damaging the electronic components (e.g., transistors and capacitors) in the first pixel circuit 201. Since static charge transmission preferentially selects the path with lower transmission impedance, this embodiment creatively sets the resistance of the third circuit connection structure 60 to be greater than the resistance of the second circuit connection structure 50. Thus, the resistance on the circuit transmission path formed by the first circuit connection structure 40 and the third circuit connection structure 60 is greater than the resistance on the circuit transmission path formed by the first circuit connection structure 40 and the second circuit connection structure 50. Consequently, more static charge preferentially passes through the first circuit connection structure 40 and the second circuit connection structure 50, which have lower transmission impedance, before being transmitted to the static discharge structure 30. This releases a significant amount of static charge at the static discharge structure 30, preventing the static charge from being transmitted to the first pixel circuit 201 and thus avoiding damage to it.

[0039] For details, please refer to [link / reference]. Figure 3 As shown, the line width of the third circuit connection structure 60 is smaller than that of the second circuit connection structure 50. Thus, the resistance of the third circuit connection structure 60 is greater than that of the second circuit connection structure 50. This ensures that more electrostatic charge will preferentially pass through the transmission path formed by the first circuit connection structure 40 and the second circuit connection structure 50, which have lower transmission impedance, and then be transmitted to the electrostatic discharge structure 30. This prevents electrostatic charge from being transmitted to the first pixel circuit 201 and avoids damage to the first pixel circuit 201.

[0040] Furthermore, the line width of the third circuit connection structure 60 is designed to be smaller than that of the second circuit connection structure 50, and the third circuit connection structure 60 and the second circuit connection structure 50 can be set on the same layer (e.g., Figure 3 (As shown) can also be set in different layers, but this application embodiment does not limit this.

[0041] Optional, Figure 5 This is a schematic diagram of a third circuit connection structure provided in an embodiment of this application, combined with... Figure 4 and Figure 5 As shown, the third circuit connection structure 60 includes a first sub-section 601 and a second sub-section 602 disposed on different layers; the first sub-section 601 and the second sub-section 602 are disposed on different layers and electrically connected through vias.

[0042] like Figure 4 and Figure 5As shown, the first sub-section 601 and the second sub-section 602, which are configured in different layers, are electrically connected by vias. The vias increase the resistance of the third circuit connection structure 60. The resistance of the third circuit connection structure 60 is greater than that of the second circuit connection structure 50. This ensures that more electrostatic charge will preferentially pass through the transmission path formed by the first circuit connection structure 40 and the second circuit connection structure 50, which have lower transmission impedance, and then be transmitted to the electrostatic discharge structure 30. This prevents electrostatic charge from being transmitted to the first pixel circuit 201 and avoids damage to the first pixel circuit 201.

[0043] Optional, continue to refer to Figure 3 and Figure 4 As shown, along the extension direction of the second circuit connection structure 50 (the Y direction as shown in the figure), the third circuit connection structure 60 is located on the side of the second circuit connection structure 50 closer to the first pixel circuit 201. That is, the third circuit connection structure 60 is not located on the electrostatic transmission path formed by the first circuit connection structure 40 and the second circuit connection structure 50. In this way, the setting of the third circuit connection structure 60 will not affect the normal transmission of electrostatic charge by the electrostatic transmission path formed by the first circuit connection structure 40 and the second circuit connection structure 50, ensuring that more electrostatic charge is released in the electrostatic release structure 30, and avoiding damage to the first pixel circuit 201 by electrostatic charge.

[0044] Optional, Figure 6 yes Figure 1 Another structural diagram of area a in the provided display panel. Figure 7 This is a schematic diagram of an electrostatic discharge substructure provided in an embodiment of this application, combined with... Figure 6 and Figure 7 As shown, the electrostatic discharge substructure 302 includes an electrostatic discharge circuit, which includes a first transistor Q1 and a second transistor Q2. The first transistor Q1 includes a first terminal S1, a second terminal D1, and a first control terminal G1. The second transistor Q2 includes a third terminal S2, a fourth terminal D2, and a second control terminal G2. The display panel also includes a first potential signal line 71 and a second potential signal line 72. The potential in the first potential signal line 71 is lower than the potential in the second potential signal line 72. The first terminal S1 is electrically connected to the first potential signal line 71. The second terminal D1, the third terminal S2, and the first control terminal G1 are all electrically connected to the discharge connection substructure 301. The fourth terminal D2 and the second control terminal G2 are both electrically connected to the second potential signal line 72.

[0045] like Figure 6 and Figure 7 As shown, the electrostatic discharge substructure 302 includes a first transistor Q1 and a second transistor Q2. Figure 6 and Figure 7Taking P-type transistors Q1 and Q2 as an example, the display panel also includes a first potential signal line 71 and a second potential signal line 72. The first terminal S1 of the first transistor Q1 is electrically connected to the first potential signal line 71. The second terminal D1 of the first transistor Q1, the third terminal S2 of the second transistor Q2, and the first control terminal G1 of the first transistor Q1 are all electrically connected to the release connection substructure 301. The fourth terminal D2 and the second control terminal G2 of the second transistor Q2 are both electrically connected to the second potential signal line 72. Thus, under normal conditions without static electricity, the voltage at the first control terminal G1 of the first transistor Q1 is the voltage signal output by the first pixel circuit 201, and the voltage at the second control terminal G2 of the second transistor Q2 is the potential voltage in the second potential signal line 72. At this time, both the first transistor Q1 and the second transistor Q2 are in a cutoff state and do not conduct, so there is no need to release static electricity. When a static charge carrying an extremely high positive voltage enters the static discharge substructure 302 via the discharge connection substructure 301, the first transistor Q1 is in the off state. The second transistor Q2 is turned on because the voltage at its third terminal S2 (static voltage) is greater than the potential voltage in the second potential signal line 72, and the static charge is released from the second potential signal line 72. Similarly, when a static charge carrying an extremely high negative voltage enters the static discharge substructure 302 via the discharge connection substructure 301, the second transistor Q2 is in the off state. The first transistor Q1 is turned on because the voltage at its first terminal S1 (potential voltage in the first potential signal line 71) is greater than the voltage at the first control terminal G1, and the static charge is released from the first potential signal line 71. Thus, by configuring the electrostatic discharge substructure 302, which includes a first transistor Q1 and a second transistor Q2, and rationally configuring the connections between the first transistor Q1 and the second transistor Q2 and the first potential signal line 71, the second potential signal line 72, and the discharge connection substructure 301, while simultaneously setting the potential in the first potential signal line 71 to be lower than the potential in the second potential signal line 72, it is ensured that both extremely high positive and extremely high negative voltage static electricity can be released through the electrostatic discharge substructure 302, guaranteeing sufficient static electricity release. Furthermore, the first potential signal line 71 can reuse the low-level signal line already configured in the display panel, and the second potential signal line 72 can reuse the high-level signal line already configured in the display panel. Therefore, during electrostatic discharge, the electrostatic discharge substructure 302 does not require additional low-level and high-level signal lines, ensuring simple wiring in the display panel. For example, the first potential signal line 71 can reuse the low-level signal line in the amplitude adjustment module, such as the PAM-VGL signal line, and the second potential signal line 72 can reuse the high-level signal line in the amplitude adjustment module, such as the PAM-VGH signal line.

[0046] Optional, Figure 8 yes Figure 1Another enlarged structural diagram of area a in the display panel shown. Figure 9 yes Figure 1 The diagram shows another enlarged structural representation of area a in the display panel shown. Figure 10 yes Figure 1 The diagram shows another enlarged view of area a in the display panel. Figure 11 yes Figure 8 The provided schematic diagram shows the cross-sectional structure of the display panel along section line A-A', combined with... Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the display panel also includes a substrate 1 and a first insulating layer 2. The electrostatic discharge substructure 302 includes an electrostatic discharge pad 3021. Along the thickness direction of the display panel (Z direction as shown in the figure), the electrostatic discharge pad 3021 overlaps with the discharge connection substructure 301 and is located on the side of the discharge connection substructure 301 closer to the substrate 1. The first insulating layer 2 is located between the film layer containing the electrostatic discharge pad 3021 and the film layer containing the discharge connection substructure 301. The first insulating layer 2 includes a first insulating portion 2a and a second insulating portion 2b. Along the thickness direction of the display panel (Z direction as shown in the figure), the first insulating portion 2a overlaps with the electrostatic discharge pad 3021, and the second insulating portion 2b does not overlap with the electrostatic discharge pad 3021. Along the thickness direction of the display panel (Z direction as shown in the figure), the thickness of the first insulating portion 2a is less than the thickness of the second insulating portion 2b.

[0047] like Figures 8-11 As shown, the display panel also includes a substrate 1 and a first insulating layer 2. Along the thickness direction of the display panel (Z direction as shown in the figure), the first insulating layer 2 is disposed between the film layer containing the electrostatic discharge pad 3021 and the film layer containing the release connection substructure 301, serving to insulate and isolate the electrostatic discharge pad 3021 and the release connection substructure 301. Furthermore, the first insulating layer 2 includes a first insulating portion 2a and a second insulating portion 2b. Along the thickness direction of the display panel (Z direction as shown in the figure), the first insulating portion 2a overlaps with the electrostatic discharge pad 3021, while the second insulating portion 2b does not overlap with the electrostatic discharge pad 3021. The thickness of the first insulating portion 2a is less than the thickness of the second insulating portion 2b. Thus, when static electricity is received, the first insulating portion 2a is preferentially broken down as a static discharge channel, while the second insulating portion 2b provides isolation and protection. That is, under high static voltage, only the first insulating portion 2a is broken down, while the second insulating portion 2b remains insulating, achieving electrostatic discharge and electrostatic protection within the display panel.

[0048] Optional, continue to refer to Figure 9As shown, the release connection substructure 301 includes a first end 301a, a second end 301b, and a connecting portion 301c. The first end 301a is electrically connected to the second circuit connection structure 50, and the connecting portion 301c connects the first end 301a and the second end 301b. The second end 301b includes an arc-shaped profile.

[0049] like Figure 9 As shown, the release connection substructure 301 includes a first end 301a, a second end 301b, and a connecting portion 301c. The second end 301b has an arc-shaped profile; that is, the boundary of the second end 301b is an arc-shaped boundary, or the boundary line of the second end 301b is rounded. There are no sharp connecting angles where the boundary lines meet at different locations. This ensures that static electricity transmitted by the release connection substructure 301 is not released at the second end 301b, thereby releasing more static electricity at the static discharge pad layer 3021, ensuring a good static discharge effect.

[0050] Optional, continue to refer to Figure 10 As shown, the release connection substructure 301 includes a first end 301a, a second end 301b, and a connecting portion 301c. The first end 301a is electrically connected to the second circuit connection structure 50, and the connecting portion 301c connects the first end 301a and the second end 301b. The second end 301b includes a first position P1 and a second position P2. Along the first direction X, the first position P1 is located on the side of the second position P2 away from the first end 301a. The width of the first position P1 in the second direction Y is smaller than the width of the second position P2 in the second direction Y. The second direction Y intersects the first direction X.

[0051] like Figure 10 As shown, the release connection substructure 301 includes a first end 301a, a second end 301b, and a connecting portion 301c. The second end 301b includes a first position P1 and a second position P2. Along the first direction X, the first position P1 is located on the side of the second position P2 away from the first end 301a, meaning the first position P1 is the end of the release connection substructure 301 without a connecting function. Furthermore, the width of the first position P1 in the second direction Y is smaller than the width of the second position P2 in the second direction Y. The second direction Y intersects the first direction X, meaning that along the second direction Y, the width corresponding to the first position P1 is smaller than the width corresponding to the second position P2, thus forming a pointed structure in the second end 301b. This pointed structure configuration of the second end 301b ensures that the electrostatic charge conducted through the release connection substructure 301 can form a pointed discharge in the second end 301b. Thus, the electrostatic charge not fully released at the electrostatic release pad 3021 can be further released at the second end 301b, ensuring sufficient release of the electrostatic charge.

[0052] Optional, Figure 12 yes Figure 1 The provided schematic diagram shows the cross-sectional structure of the display panel along section line B-B', as follows: Figure 12 As shown, the display panel also includes a substrate 1; the pixel circuit 20 includes at least one transistor Q and at least one storage capacitor Cst; the transistor Q includes an active layer 81 and a gate 82; the gate 82 is located on the side of the active layer 81 close to the substrate 10 or on the side of the active layer 81 away from the substrate 10; the storage capacitor Cst includes a first capacitor plate 83 and a second capacitor plate 84 disposed opposite to each other, the second capacitor plate 84 being located on the side of the first capacitor plate 83 away from the substrate 10; the display panel also includes a semiconductor layer POLY, a first metal layer M1, a second metal layer MC, a first source / drain electrode layer SD1, a second source / drain electrode layer SD2, and a third source / drain electrode layer SD3; the active layer 81 is located on the semiconductor layer POLY, the gate 82 and the first capacitor plate 83 are located on the first metal layer M1, and the second capacitor plate 84 is located on the second metal layer MC; the first source / drain electrode layer SD1... D1 is located on the side of the second metal layer MC away from the substrate 10; the second source / drain electrode layer SD2 is located on the side of the first source / drain electrode layer SD1 away from the substrate 10; and the third source / drain electrode layer SD3 is located on the side of the second source / drain electrode layer SD2 away from the substrate 10. The first circuit connection structure 40 is located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3. The release connection substructure 301 is located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3. The second circuit connection structure 50 is located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3.

[0053] like Figure 12 As shown, Figure 12 Only one transistor Q and one storage capacitor Cst are shown as an example. Figure 12As shown, transistor Q includes an active layer 81 and a gate 81, and storage capacitor Cst includes a first capacitor plate 83 and a second capacitor plate 84 disposed opposite to each other. The active layer 81 is located in the semiconductor layer POLY, the gate 82 and the first capacitor plate 83 are located in the first metal layer M1, and the second capacitor plate 84 is located in the second metal layer MC. Furthermore, the display panel also includes a first source / drain electrode layer SD1, a second source / drain electrode layer SD2, and a third source / drain electrode layer SD3, sequentially located on the side of the second metal layer MC away from the substrate 1. That is, the display panel includes multiple metal layers. Therefore, the first circuit connection structure 40, the release connection substructure 301, and the second circuit connection structure 50 can be disposed in at least one of the aforementioned film layers. Thus, the placement of the first circuit connection structure 40, the release connection substructure 301, and the second circuit connection structure 50 does not additionally increase the film layer structure in the display panel, which is beneficial for achieving a thinner display panel design.

[0054] Specifically, the first circuit connection structure 40 can be located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3, ensuring that the setting of the first circuit connection structure 40 does not add any additional film layer structure to the display panel. Furthermore, since the first circuit connection structure 40 extends generally along the first direction X, it can be set in the film layers of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3 where the traces are generally arranged according to the first direction X. For example, the first circuit connection structure 40 can be set in at least one of the first metal layer M1, the second metal layer MC, and the second source / drain metal layer SD2. In this way, the setting of the first circuit connection structure 40 is generally consistent with the extension direction of other traces in its film layer, and the first circuit connection structure 40 will not short-circuit with other traces in its film layer, ensuring the stable performance of the first circuit connection structure 40.

[0055] Furthermore, the release connection substructure 301 can be located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3, ensuring that the setting of the release connection substructure 301 does not add any additional film layer structure to the display panel. Moreover, since the release connection substructure 301 extends generally along the first direction X, it can be set in the film layers of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3 where the traces are generally arranged in the first direction X. For example, the release connection substructure 301 can be set in at least one of the first metal layer M1, the second metal layer MC, and the second source / drain metal layer SD2. In this way, the setting of the release connection substructure 301 is generally consistent with the extension direction of other traces in its film layer, and the release connection substructure 301 will not short-circuit with other traces in its film layer, ensuring the stable performance of the release connection substructure 301. Furthermore, to ensure sufficient space for the release connection substructure 301 and the first circuit connection structure 40, they can be placed on different layers to reduce the wiring difficulty. For example, the first circuit connection structure 40 is disposed in the second source / drain metal layer SD2, and the release connection substructure 301 is disposed in the first metal layer M1.

[0056] Furthermore, the second circuit connection structure 50 can be located in at least one of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3, ensuring that the setting of the second circuit connection structure 50 does not add additional film layer structures in the display panel. Moreover, since the second circuit connection structure 50 extends generally along the second direction Y, it can be set in the film layers of the first metal layer M1, the second metal layer MC, the first source / drain metal layer SD1, the second source / drain metal layer SD2, and the third source / drain metal layer SD3 where the traces are generally arranged in the second direction Y. For example, the release connection substructure 301 can be set in at least one of the first source / drain metal layer SD1 and the third source / drain metal layer SD3. In this way, the setting of the second circuit connection structure 50 is generally consistent with the extension direction of other traces in its film layer, and the second circuit connection structure 50 will not short-circuit with other traces in its film layer, ensuring the stable performance of the second circuit connection structure 50. Furthermore, to prevent short circuits between the second circuit connection structure 50, the first circuit connection structure 40, and the release connection substructure 301 due to their different extension directions, the second circuit connection structure 50 and the first circuit connection structure 40 can be set to be on different layers, and the second circuit connection structure 50 and the release connection substructure 301 can be set to be on different layers, ensuring that each trace is independent and the performance is stable.

[0057] Optional, Figure 13 This is a schematic diagram of another display panel structure provided in an embodiment of this application, such as... Figure 13 As shown, the display panel also includes a driving circuit 90 located in the display area AA; the driving circuit 90 is located on the side of the first light-emitting element 101 away from the edge of the display panel.

[0058] like Figure 13 As shown, the display panel provided in this embodiment may further include a driving circuit 90 located in the display area AA. The driving circuit 90 is electrically connected to the pixel circuit 20 and is used to provide control signals to the pixel circuit 20. The control signals may be control signals for writing data to the pixel circuit 20 or light-emitting control signals for emitting light to ensure the driving performance of the pixel circuit 20. Furthermore, by embedding both the pixel circuit 20 and the driving circuit 90 within the display area AA, it is beneficial to achieve an extremely narrow bezel display or a bezel-less display of the display panel 100.

[0059] Furthermore, the display panel also includes signal lines for providing signals to the driving circuit 90 to ensure the normal operation of the driving circuit 90. These signal lines may include at least one of a clock signal line, a start signal line, a reset signal line, a high-level signal line, and a low-level signal line. The driving circuit 90 is located on the side of the first light-emitting element 101 away from the edge of the display panel. This ensures that the edge of the display panel can emit light and display light because the first light-emitting element 101 is located there. It also avoids areas where the display panel edge cannot be displayed due to the pixel circuit 20 or the driving circuit 90 being located at the edge, thus enabling an extremely narrow bezel or bezel-less display panel design and improving the screen-to-body ratio.

[0060] And continue to refer to Figure 13 As shown, along the first direction X, the driving circuit 90 can be further located on the side of the pixel circuit 20 away from the edge of the display panel. For example, the driving circuit 90 can be located in the central area of ​​the display panel. In this way, the driving circuit 90 can provide control signals to the pixel circuits 20 respectively set on both sides of it, and the loss of the control signals received by the pixel circuits 20 respectively set on both sides of the driving circuit 90 during the transmission process is the same or approximately the same. This ensures that the control signals received by the pixel circuits 20 respectively set on both sides of the driving circuit 90 are the same or similar, and ensures that the driving circuit 90 has the same or similar control effect on the pixel circuits 20 respectively set on both sides of it, thus ensuring good overall display balance of the display panel.

[0061] Based on the same inventive concept, this application also provides a display device.
