Description

Technical Field

[0001] This application relates to the field of electronic circuits, specifically to a pixel electrode, an array substrate, and a display device. Background Technology

[0002] In the field of displays, some display devices achieve display by applying an electric field between two electrode plates, thereby changing the state of the medium between them. For example, liquid crystal displays (LCDs) and electronic paper displays both achieve display by changing the voltage of the pixel electrodes, thus altering the electric field between the common electrode and the pixel electrodes.

[0003] Since the pixel electrodes are located in the array substrate, which typically also contains scan lines, data lines, and other signal lines, these signal lines can affect the voltage of the pixel electrodes. Therefore, reducing the impact of these signal lines on the pixel electrodes is a key factor in improving display performance. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a pixel electrode, an array substrate, and a display device. By employing these methods, signal interference with the pixel electrode can be reduced, and the aperture ratio can be further increased, thereby improving the display effect.

[0005] One technical solution adopted in this application is to provide a pixel electrode, which includes: an electrode domain, four electrode domains arranged in a two-row, two-column array; a strip electrode, connecting two electrode domains on a set of diagonals to form a main electrode; and a ring electrode, arranged around the four electrode domains and connecting two electrode domains on another set of diagonals to form a secondary electrode.

[0006] In one embodiment, the electrode domain includes: a main electrode; and branch electrodes connected to the main electrode; wherein two main electrodes are arranged intersectingly to divide the electrode domain into four electrode subdomains.

[0007] In one embodiment, two main electrodes are arranged perpendicularly and intersecting each other, and the branch electrodes in each electrode subdomain are arranged parallel to the diagonal direction formed by the two main electrodes in the corresponding electrode subdomain.

[0008] In one embodiment, the strip electrode connects to the branch electrodes of two electrode domains on one set of diagonals, and the ring electrode connects to the main electrode and / or branch electrodes of two electrode domains on another set of diagonals.

[0009] In one embodiment, the electrode domain of the main electrode has a first recessed structure on the edge near the sub-electrode; and / or the electrode domain of the sub-electrode has a second recessed structure on the edge near the main electrode.

[0010] In one embodiment, the electrode domain includes a main electrode, two main electrodes are arranged intersectingly, and a first recessed structure and a second recessed structure of the electrode domain are disposed at the main electrode on the edge.

[0011] In one embodiment, the secondary electrode has a chamfered structure at the corner surrounding the primary electrode.

[0012] In one embodiment, the other set of diagonal electrode domains forms a corner at the connection point with the ring electrode, or at the point where the ring electrode surrounds the main electrode.

[0013] This application also provides an array substrate, which includes: scan lines; data lines; wherein the scan lines and data lines are interleaved to form a plurality of pixels distributed in an array; wherein each pixel includes a corresponding pixel electrode, a common electrode and a transistor, and the pixel electrode is the pixel electrode as described above.

[0014] This application also provides a display device, which includes an array substrate, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate, wherein the array substrate is as described above.

[0015] One technical solution adopted in this application is to provide a pixel electrode, which includes: electrode domains, four electrode domains arranged in a two-row, two-column array; a strip electrode connecting two electrode domains along a diagonal to form a main electrode; and a ring electrode surrounding the four electrode domains and connecting two electrode domains along another diagonal to form a sub-electrode. Through the above method, the pixel electrode of this embodiment has the following effects:

[0016] 1. Arrangement of electrode domains in the main and secondary electrodes. By arranging the four electrode domains in a two-row, two-column configuration, the main electrode can be better distributed throughout the entire pixel area, resulting in more complete color display.

[0017] 2. The secondary electrode is a ring electrode surrounding the main electrode. The ring electrode can reduce the interference of signals in the scan lines and data lines on the voltage of the pixel electrode. In addition, reducing the use of shielding metal can improve the pixel aperture ratio.

[0018] Therefore, by dividing the pixel electrode into multiple different electrode domains and using strip electrodes and ring electrodes to achieve different connection methods for the electrode domains, and realizing the arrangement of the sub-electrodes around the main electrode, color shift can be effectively reduced, aperture ratio can be increased, and thus the display effect can be improved.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are only for explaining this application and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all structures. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] In one application scenario, the pixel electrode in this embodiment is applied to a liquid crystal display panel, which includes an array substrate, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate. The array substrate contains scan lines, data lines, and pixel regions distributed in an array defined by the intersection of the scan lines and data lines. For each pixel region, the array substrate also includes a pixel electrode, a common electrode, and a transistor. The two ends (source and drain) of the transistor are connected to the pixel electrode and the data line, respectively, and the control terminal (gate) of the transistor is connected to the scan line. When the scan signal provided by the scan line turns on the transistor, the data signal provided by the data line is input to the pixel electrode to charge it. An electric field is generated between the pixel electrode and the common electrode, causing the liquid crystal molecules in the liquid crystal layer to deflect, thereby changing the light transmittance of the liquid crystal layer.

[0033] In another application scenario, the pixel electrode in this embodiment is used in an electronic paper display panel, such as monochrome or color electronic paper. The electronic paper display panel includes an array substrate and an electronic paper film. The array substrate contains scan lines, data lines, and pixel regions defined by the intersections of the scan lines and data lines. For each pixel region, the array substrate also includes a pixel electrode, a common electrode, and a transistor. The two ends (source and drain) of the transistor are connected to the pixel electrode and the data line, respectively, and the control terminal (gate) of the transistor is connected to the scan line. When the scan signal provided by the scan line turns on the transistor, the data signal provided by the data line is input to the pixel electrode to charge it. An electric field is generated between the pixel electrode and the common electrode, causing the particles in the electronic paper film to move, thereby achieving the display effect.

[0034] In the aforementioned application scenarios, to further improve the display effect, in one embodiment, the pixel electrode is designed with two parts: a main electrode and a sub-electrode. The main electrode is used to display the corresponding color, and its input data signal is determined by the color it displays. The sub-electrode is used for auxiliary display from multiple display angles, so that users can have a good display effect when viewing from other angles.

[0035] See Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the pixel electrode provided in this application. The pixel electrode 100 includes an electrode domain 10, a strip electrode 20, and a ring electrode 30.

[0036] The four electrode domains 10 are arranged in a two-row, two-column array; the strip electrode 20 connects two electrode domains 10 on one diagonal to form the main electrode; the ring electrode 30 surrounds the four electrode domains 10 and connects to two electrode domains 10 on another diagonal to form the secondary electrode.

[0037] Specifically, such as Figure 1 As shown, the four electrode domains 10 are the first electrode domain A, the second electrode domain B, the third electrode domain C, and the fourth electrode domain D, respectively. The first electrode domain A and the fourth electrode domain D are connected by a strip electrode 20, and the second electrode domain B and the third electrode domain C are connected by a ring electrode 30.

[0038] It is worth noting that in this embodiment, the size and dimensions of the first electrode domain A, the second electrode domain B, the third electrode domain C, and the fourth electrode domain D are not limited, and their arrangement in two rows and two columns does not necessarily have to be aligned horizontally and vertically with the pixels. For example, the direction of the scan line extension can be defined as horizontal, and the direction of the data line extension can be defined as vertical. The arrangement of the four electrode domains 10 in two rows and two columns can be roughly aligned horizontally and vertically. Figure 1 As shown, the uppermost horizontal electrode strip of the annular electrode 30 is connected to the second electrode domain B, but there is a certain distance between it and the first electrode domain A. Therefore, the upper edges of the first electrode domain A and the second electrode domain B are not flush in the horizontal direction.

[0039] Specifically, in the field of display technology, a pixel is the smallest display unit. Each pixel can display different colors or brightness levels, and the pixel electrode 100 can control the display state of a single pixel. Taking a liquid crystal display panel as an example, when the voltage applied to the pixel electrode 100 changes, the arrangement of liquid crystal molecules also changes, thereby changing the display state of the pixel and causing the image displayed by the display device to change (such as changes in brightness). The pixel electrode 100 is divided into four electrode domains 10 arranged in two rows and two columns, forming main electrodes and sub-electrodes respectively. The liquid crystal molecules of the main electrodes and sub-electrodes exhibit different alignment directions under the action of different electric fields, thereby maintaining a consistent display effect over a wider viewing angle range. This helps to reduce color shift and brightness reduction caused by changes in viewing angle, and improves the viewing angle characteristics of the display image.

[0040] Specifically, traditional display devices typically use a black matrix (BM) or shielding metal to improve display quality and reduce the impact of stray light. The black matrix is ​​primarily used for light blocking, while the shielding metal, in addition to blocking light, can also shield signals on scan lines or data lines, preventing interference from these signals on the voltage at the pixel electrodes. Both the black matrix and the shielding metal occupy a portion of the pixel's area, thus reducing the effective area for light transmission and resulting in a lower aperture ratio. A higher aperture ratio means more light can pass through the pixel, leading to higher brightness and lower power consumption.

[0041] In this embodiment, the annular electrode 30 mainly comprises two upper and lower strip electrodes and two left and right strip electrodes connected sequentially. The upper and lower strip electrodes can be arranged to correspond to the horizontal scan lines (pixel electrodes and scan lines are located in different conductive layers), and the left and right strip electrodes can be arranged to correspond to the vertical data lines (pixel electrodes and data lines are located in different conductive layers). Since the scan lines and data lines are opaque metal, they can provide a certain light-shielding effect. The main electrode formed by connecting two diagonal electrode domains 10 of the strip electrode 20 is surrounded by the secondary electrode formed by connecting two diagonal electrode domains 10 of the annular electrode 30. This not only shields the main electrode from the signal and isolates the influence of the data lines on the pixel electrodes, but also eliminates the need for a black matrix and shielding metal, effectively improving the aperture ratio. At the same time, the main electrode and the secondary electrode are not simply arranged vertically, but rather the secondary electrode surrounds the main electrode. This ensures that the main electrode is not only located in the upper or lower half of the pixel area, but is present in all parts of the pixel area, including the upper, lower, left, and right sides. Furthermore, the main electrode is more fully surrounded by the secondary electrode, resulting in a stronger shielding effect.

[0042] Optionally, the pixel electrode 100 in this embodiment is a transparent electrode. For example, it can be made of indium tin oxide (ITO). Specifically, it can be made by etching a single transparent electrode. Therefore, the electrode domain 10, the strip electrode 20, and the ring electrode 30 and their connection relationship are not connected by an additional process, but are connected by themselves.

[0043] The pixel electrode provided in this embodiment includes: electrode domains, four electrode domains arranged in a two-row, two-column array; a strip electrode, connecting two electrode domains along a diagonal to form a main electrode; and a ring electrode, surrounding the four electrode domains and connecting two electrode domains along another diagonal to form a secondary electrode. Through the above method, the pixel electrode of this embodiment has the following effects:

[0044] 1. Arrangement of electrode domains in the main and secondary electrodes. By arranging the four electrode domains in a two-row, two-column configuration, the main electrode can be better distributed throughout the entire pixel area, resulting in more complete color display.

[0045] 2. The secondary electrode is a ring electrode surrounding the main electrode. The ring electrode can reduce the interference of signals in the scan lines and data lines on the voltage of the pixel electrode. In addition, reducing the use of shielding metal can improve the pixel aperture ratio.

[0046] Therefore, by dividing the pixel electrode 100 into multiple different electrode domains 10, and using strip electrodes 20 and ring electrodes 30 to achieve different connection methods for the electrode domains, the arrangement of the sub-electrodes surrounding the main electrode can be realized, which can effectively reduce color shift, increase aperture ratio, and thus improve display effect.

[0047] See Figure 2 , Figure 2 This is a schematic diagram of the structure of the second embodiment of the pixel electrode provided in this application. The pixel electrode 100 includes an electrode domain 10, a strip electrode 20, and a ring electrode 30.

[0048] The four electrode domains 10 are arranged in a two-row, two-column array; the strip electrode 20 connects two electrode domains 10 on one diagonal to form the main electrode; the ring electrode 30 surrounds the four electrode domains 10 and connects to two electrode domains 10 on another diagonal to form the secondary electrode.

[0049] Optionally, each electrode domain 10 includes a main electrode 11 and a branch electrode 12; the branch electrode 12 is connected to the main electrode 11; wherein, the two main electrodes 11 are arranged crosswise to divide the electrode domain 10 into four electrode subdomains 13.

[0050] Specifically, the two main electrodes 11 within the electrode domain 10 are arranged in a cross pattern, dividing each electrode domain 10 into four equal-sized electrode subdomains 13. The arrangement of the liquid crystal molecules depends on the strength and direction of the electric field. The electric field strength and direction of each electrode subdomain 13 are different, resulting in different orientation angles for the liquid crystal molecules within each electrode subdomain 13.

[0051] Specifically, taking liquid crystal display as an example, the main electrode 11 establishes a basic electric field distribution within the electrode domain 10, and the branch electrode 12 forms a local electric field within the electrode sub-domain 13. By changing the intensity and direction of the local electric field, the orientation angle of the liquid crystal molecules can be controlled. In this way, even when viewing the display screen from different angles, a certain degree of brightness and color consistency can be guaranteed within each electrode sub-domain 13, which can significantly improve the viewing angle range of the display device, improve viewing angle characteristics, further reduce color shift, and improve display quality.

[0052] Optionally, the two main electrodes 11 are arranged perpendicularly to each other, that is, the two main electrodes 11 extend in the horizontal and vertical directions respectively, and the branch electrodes 12 in each electrode subdomain 13 are arranged parallel to the diagonal direction formed by the two main electrodes 11 in the corresponding electrode subdomain 13.

[0053] Specifically, within the same electrode subdomain 13, the distribution directions of each branch electrode 12 are the same and parallel to each other. The parallel distance between each branch electrode 12 affects the distribution of the electric field, and thus affects the orientation of the liquid crystal molecules. The distance between each branch electrode 12 is generally between a few micrometers and tens of micrometers.

[0054] Different shapes of the branch electrodes 12 can create different electric field distributions. For example, the branch electrodes 12 can be long and thin strips, or in other embodiments, they can be interdigitated or other shapes, which will not be listed here.

[0055] Optionally, the strip electrode 20 is connected to the branch electrodes 12 of two diagonal electrode domains 10, and the ring electrode 30 is connected to the main electrode 11 and / or branch electrodes 12 of another set of two diagonal electrode domains 10.

[0056] Specifically, the main electrode is mainly used for pixel display. The strip electrode 20 connects the branch electrodes 12 of the two diagonal electrode domains 10, so that the electrodes in the main electrode are interconnected, which helps to reduce electric field non-uniformity and thus improve display quality. The secondary electrode is mainly used for viewing angle control. The ring electrode 30 connects the main electrode 11 and / or branch electrodes 12 of the two diagonal electrode domains 10, so that the electrodes in the secondary electrode are interconnected, which helps to form multiple local electric fields. The interconnected electrodes can control the orientation of liquid crystal molecules in the electrode sub-domain 13 to achieve viewing angle control.

[0057] Specifically, a first data signal and a second data signal are applied to the main electrode and the sub-electrode, respectively. The first data signal and the second data signal can represent the same voltage signal or different voltages, forming a specific electric field distribution in the main electrode and the sub-electrode.

[0058] See also Figure 2 and Figure 3 , Figure 3 Another structural schematic diagram of the second embodiment of the pixel electrode provided in this application. In another embodiment, since the branch electrode 12 is divergent, in Figure 3 In some embodiments, electrode strips based on the electrode domain profile can also be added to the edge of each electrode domain, the profile of which can be approximately rectangular.

[0059] See Figure 4 , Figure 4 This is a schematic diagram of the structure of the third embodiment of the pixel electrode provided in this application. The pixel electrode 100 includes an electrode domain 10, a strip electrode 20, and a ring electrode 30.

[0060] The four electrode domains 10 are arranged in a two-row, two-column array; the strip electrode 20 connects two electrode domains 10 on one diagonal to form the main electrode; the ring electrode 30 surrounds the four electrode domains 10 and connects to two electrode domains 10 on another diagonal to form the secondary electrode.

[0061] Understandably, in each electrode domain, the outline around the electrode domain is defined as the edge electrode. The connection between the main electrode 11 and the edge electrode is close to the adjacent electrode domain or the ring electrode, and also close to the branch electrode 12. The electrode strips here are relatively dense, which makes the electric field here stronger than the surrounding area. Therefore, in terms of display effect, a bright spot, bright strip or bright band with a greater brightness than the surrounding area will appear here.

[0062] To address the aforementioned issues, this embodiment incorporates recessed structures at corresponding positions within each electrode domain, thereby reducing the density of the electrode strips at these locations.

[0063] Specifically, the recessed structure in the embodiment includes a first recessed structure 14 and a second recessed structure 15, and see also... Figure 2 and Figure 3 .

[0064] Optionally, the electrode domain 10 of the main electrode is provided with a first recessed structure 14 on the side edge near the sub-electrode; and / or the electrode domain 10 of the sub-electrode is provided with a second recessed structure 15 on the side edge near the main electrode.

[0065] Optionally, the electrode domain 10 includes a main electrode 11, with two main electrodes 11 arranged intersectingly, and a first recessed structure 14 and a second recessed structure 15 of the electrode domain 10 disposed at the main electrode 11 on the edge.

[0066] Specifically, a sharp electric field distribution is generated at the edge of the main electrode 11 of the electrode domain 10, which may lead to inconsistent orientation of liquid crystal molecules and affect the display effect. In the region where the electrode domain 10 of the main electrode is close to the edge of the sub-electrode and the electrode domain 10 of the sub-electrode is close to the edge of the main electrode, the angle between the main electrode and the sub-electrode is very small, and the electric field distribution between the electrodes is relatively concentrated, resulting in a stronger electric field. Color particles are adsorbed onto the surface of the liquid crystal layer near the electrode, resulting in higher display brightness and bright bands, which affect the display effect. The first recessed structure 14 and the second recessed structure 15 can weaken the electric field in this region and improve the bright bands.

[0067] In one specific embodiment, such as Figure 4 In the magnified portion of the image, since the bright band appears at the connection point of the edge electrodes in the main electrode domain, the length of the main electrode can be shortened at this point, and a notch can be provided on the edge electrode to form the aforementioned first recessed structure 14 and second recessed structure 15. The first recessed structure 14 and the second recessed structure 15 are approximately triangular hollow areas.

[0068] See Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the fourth embodiment of the pixel electrode provided in this application. Figure 6 This is a schematic diagram of the structure of the fifth embodiment of the pixel electrode provided in this application. The pixel electrode 100 includes an electrode domain 10, a strip electrode 20, and a ring electrode 30.

[0069] The four electrode domains 10 are arranged in a two-row, two-column array; the strip electrode 20 connects two electrode domains 10 on one diagonal to form the main electrode; the ring electrode 30 surrounds the four electrode domains 10 and connects to two electrode domains 10 on another diagonal to form the secondary electrode.

[0070] Figure 5 and Figure 6 The pixel electrode 100 shown is Figure 4 The main difference in the pixel electrode 100 shown is the addition of a description of the chamfer structure 16. Therefore, the following mainly describes the chamfer structure 16. For other structures in the pixel electrode 100, please refer to [link to relevant documentation]. Figure 4 The related descriptions of the illustrated embodiments, for example Figure 5 and Figure 6 The first recessed structure 14 in the middle can be seen in Figure 4 The description of the first recessed structure 14 in the middle will not be repeated here.

[0071] Optionally, the secondary electrode has a chamfered structure 16 at the corner surrounding the main electrode.

[0072] Optionally, a corner is formed at the junction of another set of diagonal electrode domains 10 and the ring electrode 30, or at the junction of the ring electrode 30 around the main electrode.

[0073] Specifically, when the angle between the main electrode and the secondary electrode is large and the distance between them is far, due to the shape and layout of the electrodes, the electric field in a specific area (such as a corner) is more concentrated in that area, forming a stronger electric field. Color particles are adsorbed onto the surface of the liquid crystal layer near the electrodes, resulting in higher brightness and bright bands.

[0074] In some alternative embodiments, such as Figure 4 As shown, the annular electrode 30 connects to two electrode domains 10 on another set of diagonals, forming a corner at the connection. The angle between the main electrode and the auxiliary electrode is large in this region, and the electric field is more concentrated in this region, forming a strong electric field. A chamfer structure 16 is set at the connection between the electrode domain 10 and the annular electrode 30, which can reduce the angle between the main electrode and the auxiliary electrode, thereby weakening the electric field here and improving the bright band.

[0075] In some alternative embodiments, such as Figure 5 As shown, since the main electrode and the secondary electrode are not connected, and the secondary electrode is arranged around the main electrode, the annular electrode 30 forms a corner around the main electrode. In this area, the angle between the main electrode and the secondary electrode is large, and the electric field is strong. Setting a chamfer structure 16 here can reduce the angle between the main electrode and the secondary electrode, thereby weakening the electric field here and improving the bright band.

[0076] See Figure 7 , Figure 7 This is a schematic diagram of an embodiment of the array substrate provided in this application; the array substrate 1000 includes a substrate 200 and a first conductive layer 300, a second conductive layer 400 and a third conductive layer 500 disposed on the substrate 200.

[0077] Understandably, in specific embodiments, the array substrate 1000 also includes transistors, insulating layers, protective layers, etc., which will not be described in detail here.

[0078] The first conductive layer 300 is an opaque metal. Data lines and scan lines are formed in the first conductive layer 300 by etching. The scan lines and data lines are interwoven to form multiple pixels distributed in an array.

[0079] The second conductive layer 400 is a transparent conductive layer, such as indium tin oxide (ITO), and forms a common electrode. Optionally, the common electrode can be a continuous sheet or a separate electrode for each pixel; this is not limited here.

[0080] The third conductive layer 500 is a transparent conductive layer, such as indium tin oxide (ITO). The third conductive layer 500 is etched to form a pixel electrode corresponding to each pixel.

[0082] The liquid crystal layer 1200 is disposed between the array substrate 1000 and the color filter substrate 1100. The array substrate 1000 is the same as described above, and will not be repeated here.

[0083] Understandably, the color filter substrate 1100 in this embodiment is a glass substrate with a color filter. The color filter decomposes white light into red, green, and blue colors, thereby achieving color display. The liquid crystal layer 1200 is located between the color filter substrate 1100 and the array substrate 1000 and is composed of liquid crystal molecules. The color filter substrate 1100 and the liquid crystal layer 1200 are components of the display device, and their specific structures are not limited here.

[0084] In other embodiments, the display device 2000 may also be an electronic paper display, such as a monochrome electronic paper display or a color electronic paper display, which will not be described in detail here.
