Description

Technical Field

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

[0002] With the rapid development of display technology, high resolution, high aperture ratio, and low power consumption have become important development directions for display panels. In existing display panels, a trigate driving architecture is often used to reduce the cost of driver integrated circuits. The trigate driving architecture is a control method that uses one data line to drive three adjacent sub-pixels simultaneously, and coordinates with multiple gate lines to conduct in a time-division multiplexing manner, thereby reducing the number of data lines and the corresponding number of IC channels, thus achieving the goal of reducing IC costs.

[0003] However, in the Trigate driving architecture, the same data line needs to charge multiple sub-pixels sequentially. The charging time of a single sub-pixel is compressed, resulting in a decrease in effective conduction current and an increase in channel impedance, which in turn reduces the overall energy efficiency. At the same time, the coordination between pixel arrangement and driving timing is not precise enough, and there are step-like abrupt changes in brightness transition between adjacent sub-pixels, which form a visual jagged appearance defect when displaying diagonal lines or curved edges.

[0022] The following disclosure provides many different embodiments for implementing different structures of this application. To simplify the disclosure of this application, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0023] Please combine Figures 1 to 6 This embodiment provides a display panel 1, which includes a pixel area 100 and a non-pixel area 200 located on at least one side of the pixel area 100. The pixel area 100 is used to display image information, and the non-pixel area 200 is used to set up driving lines or auxiliary structures.

[0024] The display panel 1 includes multiple pixel units 10, multiple data lines 20, and multiple scan lines 30 located within the pixel area 100. The multiple pixel units 10 are arranged along a first direction X and a second direction Y. Each pixel unit 10 includes multiple sub-pixel groups 11. Each sub-pixel group 11 includes two sub-pixels 111. The two sub-pixels 111 have the same color and are staggered in both the first direction X and the second direction Y. The first direction X intersects the second direction Y. The first direction X can be the length direction of the display panel 1, and the second direction Y can be the width direction of the display panel 1.

[0025] Multiple data lines 20 are arranged at intervals along a first direction X, with one data line 20 between two adjacent columns of pixel units 10; multiple scan lines 30 are arranged at intervals along a second direction Y, with one scan line 30 between two adjacent rows of sub-pixels 111; specifically, each data line 20 is connected to one pixel unit 10 in each row, and two sub-pixels 111 in each sub-pixel group 11 are connected to the same data line 20; each scan line 30 is connected to one sub-pixel group 11 in each pixel unit 10, and two sub-pixels 111 in each sub-pixel group 11 are connected to the same scan line 30. Since the two sub-pixels 111 in each sub-pixel group 11 share the same scan line 30, when the scan line 30 is selected, the two sub-pixels 111 are synchronously turned on and simultaneously receive data voltage from the same data line 20. Therefore, in each scan cycle, the voltage output by the data line 20 is simultaneously written to two sub-pixels 111 of the same color.

[0026] Understandably, compared to the problem in traditional tri-gate architecture where the same data line 20 needs to charge multiple sub-pixels 111 sequentially, resulting in a compressed charging time for each sub-pixel 111, this embodiment connects two sub-pixels 111 in each sub-pixel group 11 to the same data line 20. This allows the voltage output by the data line 20 to charge both sub-pixels 111 simultaneously, thereby writing more charge within the same scan time. This effectively extends the effective charging time of each sub-pixel 111, making the effective charging time of these two sub-pixels 111 longer than the sequential charging method of multiple sub-pixels 111 in related technologies. This improves driving capability and avoids energy efficiency degradation due to insufficient charging time. At the same time, since the two sub-pixels 111 in each sub-pixel group 11 are controlled by the same scan line 30, the two sub-pixels 111 can be driven synchronously, thereby improving the charging efficiency of the sub-pixels 111 without increasing the number of data lines 20.

[0027] Furthermore, compared to the prior art where sub-pixels 111 of the same color are aligned along the row or column direction of the display panel 1, this embodiment sets two sub-pixels 111 of the same color to be staggered in both the first direction X and the second direction Y. This makes the sub-pixels 111 of the same color, which were originally aligned in the vertical direction, become staggered. When displaying diagonal or curved edges, the brightness of the sub-pixels 111 of the same color between adjacent rows in the conventional alignment will change abruptly from present to absent, forming an obvious step-like jump. However, in this embodiment, since the sub-pixels 111 of the same color are offset in both the row and column directions, the brightness change is distributed to multiple staggered sub-pixels 111. The brightness transition between adjacent rows no longer presents a single step, but forms a gradual brightness distribution along the diagonal direction, thereby improving the problem of jagged edges on the display.

[0028] Furthermore, each sub-pixel 111 includes a driving device 40 and a pixel electrode 51 electrically connected to the driving device 40. The driving device 40 includes a driving gate 41. The data line 20 is used to transmit data signals to each pixel electrode 51 to realize independent driving of the sub-pixel 111. The scan line 30 is used to independently scan and control the driving gate 41 of each sub-pixel 111, thereby selecting the sub-pixel 111 row by row, so that the voltage on the data line 20 can be written to the corresponding pixel electrode 51 in sequence.

[0029] It should be noted that in the relevant technology, each sub-pixel 111 needs to be equipped with an independent driving device 40 (such as a thin film transistor), which results in a large number of driving devices 40, occupying more wiring space and affecting the aperture ratio.

[0030] Specifically, within the same sub-pixel group 11, two sub-pixels 111 of the same color share a single driver device 40, and the pixel electrodes 51 of the two sub-pixels 111 are interconnected. Since the pixel electrodes 51 of the two sub-pixels 111 are electrically connected to each other and share the drain 662 output terminal of the same driver device 40, when the gate of the driver device 40 receives an enable signal on the scan line 30 and the source 661 receives a data voltage on the data line 20, the driver device 40 simultaneously provides the same driving voltage to the two pixel electrodes 51.

[0031] Understandably, compared to configuring a driving device 40 independently for each sub-pixel 111, this embodiment reduces the number of driving devices 40 by having two sub-pixels 111 of the same color share a single driving device 40 within the same sub-pixel group 11, and connecting the pixel electrodes 51 of the two sub-pixels 111 to each other. This reduces the area occupied by the driving devices 40 in the display panel 1 and helps to improve the aperture ratio of the display panel 1. At the same time, since the two pixel electrodes 51 are connected to each other, there is no potential difference between them, ensuring that the two sub-pixels 111 of the same color have completely consistent brightness, avoiding display unevenness caused by driving differences.

[0032] It should be noted that the pixel electrodes 51 of two sub-pixels 111 of the same color can be connected to the drain 662 through the same contact hole, or they can be connected to each other through metal traces and then connected to the drain 662. This embodiment does not limit this.

[0033] Furthermore, in the sub-pixel group 11, the two sub-pixels 111 are staggered by the distance of one sub-pixel 111 in the first direction X and the second direction Y, so that in the same sub-pixel group 11, the two sub-pixels 111 form a diagonal staggered arrangement in the first direction X and the second direction Y.

[0034] It should be noted that the above-mentioned "misalignment" refers to the relative positional relationship of two sub-pixels 111 in the first direction X and the second direction Y; specifically, in the same sub-pixel group 11, the projections of two sub-pixels 111 in the first direction X and the second direction Y do not overlap at all (that is, the two sub-pixels 111 are neither in the same row nor in the same column).

[0035] It is understandable that when the misalignment distance is less than one sub-pixel 111 (for example, two sub-pixels are misaligned by half a sub-pixel distance in the first or second direction, and the projections of the two sub-pixels in the first or second direction partially overlap), the brightness change is still concentrated in a narrow area and cannot be effectively dispersed. Compared with the scheme where the misalignment distance is less than one sub-pixel 111, the misalignment distance of one sub-pixel in this embodiment makes the projections of the two sub-pixels 111 in the first direction X and the second direction Y completely non-overlapping. This enables the brightness change that was originally concentrated in the same row or column in the same pixel unit 10 to be completely dispersed into two adjacent rows and two columns, thereby eliminating the step-like jump caused by the brightness step change when adjacent sub-pixels 111 are vertically aligned, and significantly improving the smoothness of the display edge.

[0036] Specifically, when the slope of the display line is 45° (the slope refers to the tangent of the angle between the display edge and the horizontal direction; a 45° display line means that the display edge forms a 45° angle with the horizontal direction), since the two sub-pixels 111 of the same color are located in different rows and columns, and the two sub-pixels 111 differ from each other by one sub-pixel spacing in the first direction X and the second direction Y, the positions of these two sub-pixels 111 are symmetrically distributed relative to the display line.

[0037] Understandably, in related technologies, subpixels 111 of the same color are located in the same column. When a 45° display line passes through, the brightness is provided solely by the subpixels 111 in that column, resulting in a 90° right-angle jagged edge. In this embodiment, because two subpixels 111 of the same color are staggered, the brightness in the area traversed by the display line is jointly provided by two subpixels 111 located in different columns, and the relative positions of the two subpixels 111 ensure a uniform transition of brightness along the direction of the display line. Therefore, when the human eye observes the edge of the display line, the perceived edge is no longer the 90° right-angle jagged edge formed by a single column of subpixels 111 in related technologies, but rather an approximately smooth line composed of multiple small steps. The height and width of these small steps are limited to the range of one subpixel 111, making them difficult to distinguish at normal viewing distances, thereby improving the continuity of the edge display.

[0038] Furthermore, the pixel unit 10 includes two adjacent sub-pixel groups 11 arranged along the second direction Y, wherein the color of the sub-pixel 111 of one sub-pixel group 11 is different from the color of the sub-pixel 111 of the other sub-pixel group 11, thereby making the colors of different sub-pixel groups 11 within the same pixel unit 10 alternately distributed, avoiding spatial color accumulation caused by adjacent sub-pixel groups 11 having the same color, and ensuring the uniformity of color display.

[0039] Specifically, sub-pixel group 11 includes a first sub-pixel 111A and a second sub-pixel 111B. The first sub-pixel 111A and the second sub-pixel 111B have the same color, and the first sub-pixel 111A and the second sub-pixel 111B are staggered in the first direction X and the second direction Y. In the same pixel unit 10, the first sub-pixel 111A of one sub-pixel group 11 is arranged and adjacent to the first sub-pixel 111A of another sub-pixel group 11 along the second direction Y, and the first sub-pixel 111A of the other sub-pixel group 11 is arranged and adjacent to the second sub-pixel 111B of one sub-pixel group 11 along the first direction X. Thus, in the first sub-pixel group 11A and the second sub-pixel group 11B, a mosaic structure in which two sub-pixels 111 are embedded in each other is formed, so that the colors of different sub-pixel groups 11 in the same pixel unit 10 are cross-distributed in both the row and column directions, avoiding color accumulation or sparseness caused by improper misalignment, and improving the fineness and spatial uniformity of the image display.

[0040] It should be noted that the aforementioned "misalignment" refers to the relative positional relationship between the first sub-pixel 111A and the second sub-pixel 111B in the first direction X and the second direction Y. Specifically, the projections of the first sub-pixel 111A and the second sub-pixel 111B in the first direction X and the second direction Y are completely non-overlapping (i.e., the two sub-pixels are neither in the same row nor in the same column). In this embodiment, since the first sub-pixel 111A and the second sub-pixel 111B are both misaligned by one sub-pixel distance in the first direction X and the second direction Y, this is a case where the projections are completely non-overlapping. By setting the first sub-pixel 111A and the second sub-pixel 111B to be misaligned in the first direction X and the second direction Y, the brightness contribution of the first sub-pixel 111A and the second sub-pixel 111B is completely distributed to different rows and columns, avoiding brightness concentration caused by partial overlap of projections, thereby eliminating the problem of jagged edges in the display and improving display uniformity.

[0041] Meanwhile, the aforementioned "adjacent" means that, within the same pixel unit 10, the first sub-pixel 111A of one sub-pixel group 11 overlaps with the projection of the first sub-pixel 111A of another sub-pixel group 11 in the second direction Y, thus placing them in the same column; and the first sub-pixel 111A of another sub-pixel group 11 overlaps with the projection of the second sub-pixel 111B of one sub-pixel group 11 in the first direction X, thus placing them in the same row. This results in different sub-pixel groups 11 within the same pixel unit 10 forming a cross-distribution in both the row and column directions, avoiding color accumulation or sparseness caused by improper misalignment, and improving the fineness and spatial uniformity of the image display.

[0042] Furthermore, in two adjacent pixel units 10 along the second direction Y, the two pixel units 10 have two adjacent sub-pixel groups 11 along the second direction Y, and the color of the sub-pixel 111 of the sub-pixel group 11 of one pixel unit 10 is different from the color of the sub-pixel 111 of the other sub-pixel group 11; wherein, the first sub-pixel 111A of one sub-pixel group 11 is arranged and adjacent to the first sub-pixel 111A of the other sub-pixel group 11 along the second direction Y, and the first sub-pixel 111A of the other sub-pixel group 11 is arranged and adjacent to the second sub-pixel 111B of one sub-pixel group 11 along the first direction X, so that the sub-pixels 111 between two adjacent pixel units 10 form a staggered nesting in the second direction Y, so that sub-pixels 111 of different colors located in different pixel units 10 appear alternately in the second direction Y, and sub-pixels 111 of different colors are continuously stacked in the second direction Y, thereby avoiding the continuous accumulation of sub-pixels 111 of the same color in the second direction Y.

[0043] Understandably, since sub-pixels 111 of the same color no longer stack along the second direction Y, their brightness contribution is distributed to different columns. Therefore, the color distribution of the display screen 1 is more uniform, avoiding local color blocks or brightness concentration. At the same time, by distributing the brightness abrupt change to multiple different columns and rows, the brightness transition at the junction of adjacent pixel units 10 is made smoother, thereby further improving the problem of jagged edges on the display.

[0044] Further, the plurality of pixel units 10 includes a plurality of first pixel units 101, a plurality of second pixel units 102, and a plurality of third pixel units 103 arranged sequentially along a first direction X; the plurality of first pixel units 101, the plurality of second pixel units 102, and the plurality of third pixel units 103 are respectively arranged along a second direction Y, and each of the first pixel units 101, the second pixel units 102, and the third pixel units 103 includes a first sub-pixel group 11A, a second sub-pixel group 11B, and a third sub-pixel group 11C; the sub-pixel 111 color of the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C... The colors of sub-pixels 111 and 111 of the third sub-pixel group 11C are different; wherein, in the first pixel unit 101, the second pixel unit 102 and the third pixel unit 103, the arrangement order of sub-pixel group 11 in the second direction Y in the second pixel unit 102 is cyclically shifted by one position relative to the arrangement order of sub-pixel group 11 in the second direction Y in the first pixel unit 101, and the arrangement order of sub-pixel group 11 in the third pixel unit 103 is cyclically shifted by one position relative to the arrangement order of sub-pixel group 11 in the second direction Y in the second pixel unit 102.

[0045] It should be noted that the above-mentioned "one-position cyclic misalignment" refers to the following: assuming that the first pixel unit 101 includes three sub-pixel groups A, B, and C arranged sequentially along the second direction Y, then the second pixel unit 102 includes three sub-pixel groups B, C, and A arranged sequentially along the second direction Y, and the third pixel unit 103 includes three sub-pixel groups C, A, and B arranged sequentially along the second direction Y; that is, the sub-pixel group arrangement order of each subsequent pixel unit is based on the order of the previous pixel unit, shifted one position along the second direction.

[0046] It is important to emphasize that the aforementioned "misalignment by one position" refers to moving the entire sub-pixel group as a whole. There can be one, two, or more sub-pixel groups. For example, when there are two sub-pixel groups, the order of the first pixel unit 101 can be represented as A1A2→B1B2→C1C2, the order of the second pixel unit 102 is B1B2→C1C2→A1A2, and the order of the third pixel unit 103 is C1C2→A1A2→B1B2. Here, A1, A2, B1, B2, C1, and C2 are all sub-pixel groups, and each sub-pixel group includes two sub-pixels. The two sub-pixels have the same color and are misaligned in both the first and second directions. For details, please refer to [link to relevant documentation]. Figure 5 The first sub-pixel unit 101 includes two first sub-pixel groups (A1 and A2), two second sub-pixel groups (B1 and B2), and two third sub-pixel groups (C1 and C2).

[0047] Specifically, based on the order A→B→C of the first pixel unit 101, the order of the second pixel unit 102 is B→C→A, that is, the arrangement order of the sub-pixel groups 11 in the second pixel unit 102 is cyclically shifted by one position relative to the arrangement order of the sub-pixel groups 11 in the first pixel unit 101; the order of the third pixel unit 103 is C→A→B, that is, the arrangement order of the sub-pixel groups 11 in the third pixel unit 103 is cyclically shifted by one position again based on the second pixel unit 102.

[0048] It is understandable that by setting the arrangement order of sub-pixel groups 11 in the second pixel unit 102 in the second direction Y to be cyclically shifted by one position relative to the arrangement order of sub-pixel groups 11 in the second direction Y of the first pixel unit 101, and the arrangement order of sub-pixel groups 11 in the third pixel unit 103 in the second direction Y to be cyclically shifted by one position relative to the arrangement order of sub-pixel groups 11 in the second pixel unit 102, the sub-pixel groups corresponding to the same position in adjacent pixel units along the first direction X are sequentially shifted by one position in the second direction Y. Thus, when a 45° display diagonal line passes through, the color sequence of the sub-pixel groups remains consistent (for example, it is a cycle of the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C), avoiding color abrupt changes and ensuring the color uniformity and continuity of the display diagonal line edge.

[0049] It should be noted that this embodiment uses the example of sub-pixel 111 of the first sub-pixel group 11A being green, sub-pixel 111 of the second sub-pixel group 11B being red, and sub-pixel 111 of the third sub-pixel group 11C being blue.

[0050] Specifically, the arrangement order of the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C in the second direction Y is different. In the first pixel unit 101, the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C are arranged sequentially along the second direction Y; in the second pixel unit 102, the second sub-pixel group 11B, the third sub-pixel group 11C, and the first sub-pixel group 11A are arranged sequentially along the second direction Y; in the third pixel unit 103, the third sub-pixel group 11C, the first sub-pixel group 11A, and the second sub-pixel group 11B are arranged sequentially along the second direction Y; wherein, the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C in the first pixel unit 101 are arranged sequentially along the second direction Y; The second sub-pixel group 11B of the two-pixel unit 102 and the third sub-pixel group 11C of the third pixel unit 103 are arranged sequentially along the first direction X; the second sub-pixel group 11B of the first pixel unit 101, the third sub-pixel group 11C of the second pixel unit 102 and the first sub-pixel group 11A of the third pixel unit 103 are arranged sequentially along the first direction X; the second sub-pixel group 11B of the third pixel unit 103, the first sub-pixel group 11A of the second pixel unit 102 and the second sub-pixel group 11B of the third pixel unit 103 are arranged sequentially along the first direction X, so that the sub-pixels 111 in two adjacent sub-pixel groups 11 along the first direction X and the second direction Y are all different in color.

[0051] Furthermore, between a sub-pixel 111 of the first sub-pixel group 11A of the first pixel unit 101 arranged along the first direction X and a sub-pixel 111 of the second sub-pixel group 11B of the second pixel unit 102, a sub-pixel 111 of the third sub-pixel group 11C of the first pixel unit 101 adjacent to the first pixel unit 101 is also provided; between a sub-pixel 111 of the second sub-pixel group 11B of the second pixel unit 102 arranged along the first direction X and a sub-pixel 111 of the third sub-pixel group 11C of the third pixel unit 103, a sub-pixel 111 of the first sub-pixel group 11A of the second pixel unit 102 adjacent to the second pixel unit 102 is also provided. 1; A sub-pixel 111 of the second sub-pixel group 11B of the second pixel unit 102 arranged along the first direction X, and a sub-pixel 111 of the third sub-pixel group 11C of the third pixel unit 103, on the side of the sub-pixel 111 of the third sub-pixel group 11C of the third pixel unit 103 away from the sub-pixel 111 of the second sub-pixel group 11B of the third pixel unit 103, is also provided, such that there is at least one sub-pixel 111 of another color between any two different pixel units 10 of the same color arranged along the first direction X.

[0052] Understandably, by ensuring that the colors of the sub-pixels 111 of the first sub-pixel group 11A, the second sub-pixel group 11B, and the third sub-pixel group 11C are all different within any pixel unit 10, and by employing different sub-pixel group 11 arrangements in the second direction Y for adjacent pixel units 10, it is ensured that any two adjacent sub-pixel groups 11 in the display panel 1 have different colors, thus avoiding any continuous accumulation of sub-pixels 111 of the same color on the two-dimensional plane. Since the brightness abrupt change is distributed across sub-pixels 111 of different colors, and the sub-pixels 111 of each color alternate evenly, the display image exhibits a uniform color distribution macroscopically, without local color shifts; microscopically, the brightness transition at the diagonal edge is shared by multiple sub-pixels 111 of different colors and positions, further weakening the visual jaggedness.

[0053] Please continue to combine Figures 1 to 6 In one embodiment, the display panel 1 can be a liquid crystal display panel 1, which includes a first substrate 60 and a second substrate 70 disposed opposite to each other, and a liquid crystal layer 80 located between the first substrate 60 and the second substrate 70. The first substrate 60 can be an array substrate, the second substrate 70 is a counter substrate, and the first substrate 60 and the second substrate 70 are sealed to form a liquid crystal cell to accommodate the liquid crystal layer 80. The liquid crystal layer 80 includes a plurality of liquid crystal molecules, and the arrangement of the liquid crystal molecules changes the light transmittance as the electric field between the two substrates changes to achieve display.

[0054] The first substrate 60 includes a first base 61 and an array layer located on the first base 61. The array layer may include multiple thin-film transistors (TFTs). The TFTs are used to control the on and off states of the corresponding pixel electrodes 51, thereby achieving precise driving of liquid crystal molecules and image display. The TFTs may be etch-block type, back-channel etch type, or, depending on the position of the driving gate 41 and the active layer 65, may be classified as bottom-gate TFTs, top-gate TFTs, etc. This embodiment does not impose any limitations on these structures.

[0055] The second substrate 70 includes a second substrate 71, a color filter layer 72 located on the side of the second substrate 71 near the first substrate 60, and a planarization layer located on the side of the color filter layer 72 near the first substrate 60. The color filter layer 72 includes a plurality of spaced color resist units 721 and a black matrix 722 disposed between two adjacent color resist units 721. The black matrix 722 may be in the form of a mesh structure.

[0056] Furthermore, the first substrate 60 may include a first electrode layer 62 on the first substrate 61, a gate layer 63 on the first electrode layer 62, a gate insulating layer 64 on the gate layer 63, an active layer 65 on the gate insulating layer 64, a second electrode layer 66 on the active layer 65, a passivation layer 67 on the second electrode layer 66, and a third electrode layer 68 on the passivation layer 67; wherein the materials of the first electrode layer 62, the second electrode layer 66, and the third electrode layer 68 may all be transparent conductive materials.

[0057] The first electrode layer 62 includes a pixel electrode layer 50, which includes a plurality of pixel electrodes 51; the gate layer 63 includes a driving gate 41 and a scan line 30; the second electrode layer 66 includes a source 661, a drain 662, a data line 20, and a common electrode line 663; the third electrode layer 68 includes a common electrode layer 90, which includes a plurality of common electrodes 91; that is... Figure 6 The pixel electrode layer 50 is at the bottom layer, and the common electrode layer 90 is at the top layer.

[0058] Specifically, the pixel electrode layer 50 and the common electrode layer 90 are both disposed on the first substrate 60. The pixel electrode layer 50 serves as a partition electrode driven by the corresponding thin film transistor and is used to apply driving signals to each pixel unit 10. The common electrode layer 90 is disposed in the upper structure of the first substrate 60 and can form a continuous common electrode surface. Together with the pixel electrode layer 50, it forms a vertical electric field or a lateral electric field to regulate the orientation of liquid crystal molecules in the corresponding region.

[0059] Furthermore, sub-pixel 111 includes a common electrode 91 corresponding to pixel electrode 51, and the common electrodes 91 of two adjacent sub-pixels 111 are electrically connected to each other; wherein, the display panel 1 has a through hole 12, the through hole 12 penetrates the passivation layer 67, and exposes part of the common electrode line 663, the common electrode 91 is electrically connected to the common electrode line 663 through the through hole 12, thereby realizing that the common signal is transmitted from the common electrode line 663 to the common electrode 91 of each sub-pixel 111, ensuring that each sub-pixel 111 can obtain a stable common potential.

[0060] Specifically, multiple common electrode lines 663 are spaced apart along the first direction X, extend along the second direction Y, and are located in the non-transparent gap between two adjacent pixel units 10 in the first direction X. Since both the common electrode lines 663 and the data lines 20 are located on the second electrode layer 66, they can be fabricated simultaneously using the same photomask process. Therefore, the linewidth of the common electrode lines 663 can achieve the same micron-level processing precision as the data lines 20, without requiring additional mask costs. Furthermore, the linewidth of the common electrode lines 663 themselves can be precisely controlled to a small size, without significant widening due to process deviations.

[0061] Understandably, in related technologies, the width of the black matrix 722 needs to cover the entire metal trace area between pixel units 10, with an additional margin for alignment deviation to prevent light leakage due to photolithography alignment errors. In this embodiment, the common electrode line 663 is fabricated synchronously with the data line 20, with precise line width and fixed position. Its actual lateral width is determined and predictable, eliminating the need to increase the width of the black matrix 722 to compensate for alignment deviations. Therefore, the coverage width of the black matrix 722 between adjacent pixel units 10 can be reduced, allowing the black matrix 722 to only block the narrow area where the common electrode line 663 and data line 20 are located, thereby releasing more light-transmitting area and effectively improving the aperture ratio of the display panel 1.

[0062] It should be noted that in this embodiment, the first electrode layer 62 includes a pixel electrode layer 50, the third electrode layer 68 includes a common electrode layer 90, and the common electrode line 663 is located at the non-transparent gap between two adjacent pixel units 10 in the first direction X. These are only illustrative examples and are not intended to limit the scope of protection of this embodiment. Please refer to... Figure 1 , Figure 7 and Figure 8 In another embodiment, the first electrode layer 62 includes a common electrode layer 90; the third electrode layer 68 includes a pixel electrode layer 50, i.e. Figure 8 The common electrode layer 90 is at the bottom, and the pixel electrode layer 50 is at the top.

[0063] exist Figure 8 In the illustrated embodiment, the display panel 1 includes a first opening 13 and a second opening 14. The first opening 13 penetrates the passivation layer 67 and exposes a portion of the common electrode line 663. The second opening 14 penetrates the passivation layer 67 and the gate insulating layer 64 and exposes a portion of the common electrode 91. The third electrode layer 68 also includes a connecting electrode 681. One end of the connecting electrode 681 is electrically connected to the common electrode line 663 through the first opening 13, and the other end of the connecting electrode 681 is electrically connected to the common electrode 91 through the second opening 14. This enables the common signal to be transmitted from the common electrode line 663 to the common electrode 91 of each sub-pixel 111, ensuring that each sub-pixel 111 can obtain a stable common potential.

[0064] Furthermore, the common electrode line 663 is located between two adjacent sub-pixels 111 in the first direction X, and the data line 20 is located between two adjacent columns of the pixel units 10. By placing the pixel electrode layer 50 on the top layer, the vertical distance between the pixel electrode layer 50 and the common electrode line 663 and the data line 20 is reduced, thereby reducing the parasitic capacitance effect between different electrode layers. Due to the reduction in parasitic capacitance, the interference of the electric field generated by the data line 20 on the liquid crystal deflection is weakened. Therefore, when setting the black matrix 722, it is no longer necessary to retain a large light-shielding width to shield the stray electric field at the edge of the data line 20. The width of the black matrix 722 at the corresponding position of the data line 20 can be reduced, allowing more light to pass through the pixel area 100, thereby improving the transmittance of the display panel 1.
