Description

Technical Field

[0001] The present application belongs to the field of display driving technology, and in particular relates to a pixel driving architecture, a display panel, and a pixel driving method. Background Art

[0002] In existing technologies, Long V mode (Long Vertical, inter-frame touch drive) avoids display interference by limiting touch actions to the vertical blanking area (V Blank), but the touch reporting rate is tied to the display refresh rate, making it difficult to achieve high reporting rate requirements. Another Long H mode (Long Horizontal, intra-frame touch drive) improves the reporting rate by inserting touch actions during frame refresh. However, the display interruption at the paused line position can cause noticeable horizontal stripes, seriously degrading display quality. Therefore, with the popularization of high refresh rate displays, traditional drive modes cannot simultaneously meet customer needs for high touch reporting rates and zero horizontal stripes. How to maintain the high reporting rate advantage of Long H mode while effectively eliminating horizontal stripes caused by display pauses has become a technical challenge that the industry urgently needs to solve. Summary of the Invention

[0007] In a possible embodiment, the plurality of scan lines further include a Gn+1 scan line, which is used to input scan signals to the pixel units in the odd columns of the n+1th row of the pixel array and to the pixel units in the even columns of the n+2th row of the pixel array.

[0008] In a possible embodiment, the Gn scan line is wavy, and the Gn scan line includes multiple bending structures. In each two adjacent bending structures, the end of one bending structure is connected to the head end of the other bending structure. Each of the bending structures surrounds two pixel areas, and the two pixel units in the same row are arranged in the two pixel areas.

[0009] In a possible embodiment, each of the bending structures includes a first segment, a second segment, a third segment, and a fourth segment connected in sequence, wherein the first segment is located on a side of the pixel unit in the odd column of the nth row of the pixel array away from the pixel unit in the odd column of the n+1th row of the pixel array, the second segment is located between two adjacent pixel units in the nth row of the pixel array, the third segment is located between the pixel unit in the even column of the nth row of the pixel array and the pixel unit in the even column of the n+1th row of the pixel array, and the fourth segment is located between another two adjacent pixel units in the nth row of the pixel array.

[0012] In another aspect, the present application provides a display panel, comprising: The above pixel driving architecture.

[0013] On the other hand, the present application provides a pixel driving method for the above-mentioned pixel driving architecture, comprising the following steps: When it is determined that the next frame is an odd frame, the timing controller controls the scan line to input a scan signal to the pixel array according to the first mode; When it is determined that the next frame is an even frame, the timing controller controls the scan line to input a scan signal to the pixel array according to the second mode; The first mode is different from the second mode.

Figure 4 is a schematic diagram of a pixel driving architecture provided in the second embodiment of the present application, Figure 5 This is a display effect diagram of a display panel formed by the pixel driving architecture provided in the second embodiment of the present application.

[0023] The pixel drive architecture provided in the present application includes a pixel array, multiple scan lines, and multiple data lines. The pixel array includes multiple pixel units arranged in an array, and the pixel array formed by the multiple pixel units is a pixel array formed by RGB pixels. Multiple data lines are arranged in sequence along the row direction of the pixel array. The multiple scan lines and the multiple data lines enclose multiple pixel regions. Multiple pixel units are respectively arranged in the multiple pixel regions, and each pixel unit is electrically connected to a scan line and a data line. The scan line is electrically connected to the gate electrode for providing a scan signal to the pixel unit connected thereto. The data line is electrically connected to the source electrode for providing a data signal to the pixel unit connected thereto. A scan line is provided between each adjacent pixel unit in the same row, that is, at least a portion of the scan line is bent and arranged in the pixel drive architecture, and at least a portion of the scan line extends along the column direction of the pixel array between each adjacent pixel unit in the same row. Multiple pixel units in the same row are provided with scan signals by at least two scan lines, that is, multiple pixel units in the same row are electrically connected to at least two scan lines. Pixel units in the same column are provided with data signals by a data line to maintain signal consistency.

[0024] The pixel drive architecture provided by the present application is characterized by a scan line being provided between every two adjacent pixel units in the same row, and multiple pixel units in the same row are provided with scan signals by at least two scan lines. When the display is paused or refreshed, some pixel units in the row are illuminated, while other pixel units cannot be illuminated. The pixel units corresponding to the row appear as two rows of staggered and discontinuous lines. Compared with traditional horizontal stripes that run through the line, the horizontal stripe display effect in the screen formed by the pixel drive architecture provided by the present application is weakened. While maintaining the high reporting rate advantage of the Long H mode, it can effectively eliminate the horizontal stripes caused by display pauses, thereby improving the display quality.

[0025] See also Figure 2 and Figure 4 In the pixel driving architecture provided in the present application, the multiple scan lines include a G0 scan line extending along the row direction of the pixel array. The G0 scan line is arranged on a side of the pixel unit of the first row of the pixel array away from the pixel unit of the second row of the pixel array. The G0 scan line is electrically connected to the pixel units of the even columns of the first row of the pixel array. The G0 scan line is used to input a scan signal to the pixel units of the even columns of the first row of the pixel array.

[0026] Exemplarily, the plurality of pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, the G0 scan line is arranged at the top of the pixel units in the first row of the pixel array and extends roughly along the row direction of the pixel array, and the G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array to provide a scan signal to G0, R1, and B1 in the first row of the pixel array.

[0027] When the screen display is paused at the first row of the pixel array, only G0, R1, and B1 of the first row of the pixel array are lit, while R0, B0, and G1 are not lit. At this time, only half of the pixel units in the first row of the pixel array are lit, and the horizontal stripes are not displayed in the form of straight lines, but in the form of discontinuous lines. This can effectively eliminate the horizontal stripes caused by the display pause, thereby improving the display quality.

[0028] See also Figure 2 and Figure 3 In the pixel driving architecture provided in the first embodiment of the present application, the plurality of scan lines include the G0 scan line and the G n Scan line, G0 scan line extends along the row direction of the pixel array, G0 scan line is set on the side of the pixel unit of the first row of the pixel array away from the pixel unit of the second row of the pixel array, G0 scan line is electrically connected to the pixel unit of the even column of the first row of the pixel array, G0 scan line is used to input scan signals to the pixel unit of the even column of the first row of the pixel array. nThe scan line is used to input scan signals to the pixel units in the odd columns of the nth row of the pixel array and to the pixel units in the even columns of the n+1th row of the pixel array, where n≥1 and n is an integer.

[0029] Among them, part of G n The scan line is set on the side of the pixel unit of the odd column of the nth row of the pixel array away from the pixel unit of the odd column of the n+1th row of the pixel array, and the other part G n The scan line is between two adjacent pixel units in the nth row of the pixel array, and then a part of G n The scan line is set between the pixel units of the even columns of the nth row of the pixel array and the pixel units of the even columns of the n+1th row of the pixel array. n The scan line inputs scan signals to the pixel units in the odd columns of the n-th row of the pixel array and to the pixel units in the even columns of the (n+1)-th row of the pixel array.

[0030] Exemplarily, the multiple pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, the multiple pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence, the multiple pixel units in the third row of the pixel array include R4, G4, B4, R5, G5, and B5 arranged in sequence, and the multiple pixel units in the fourth row of the pixel array include R6, G6, B6, R7, G7, and B7 arranged in sequence.

[0031] When n=1, the plurality of scan lines include a G0 scan line and a G1 scan line. The G0 scan line is disposed at the top of the pixel unit in the first row of the pixel array and extends substantially along the row direction of the pixel array. The G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array. A portion of the G1 scan lines is disposed on a side of the pixel unit in the odd column of the first row of the pixel array away from the pixel unit in the odd column of the second row of the pixel array. Another portion of the G1 scan lines is disposed between two adjacent pixel units in the first row of the pixel array. Another portion of the G1 scan lines is disposed between a pixel unit in the even column of the first row of the pixel array and a pixel unit in the even column of the second row of the pixel array. The G1 scan line is electrically connected to R0, G2, B0, R3, G1, and B3 of the pixel array in sequence to provide scan signals to R0, G2, B0, R3, G1, and B3 of the pixel array.

[0032] In other words, the arrangement of the G1 scan line is as follows: the G1 scan line extends from the top of R0 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between R0 and G0, then extends along the row direction of the pixel array at the bottom of G0, then extends upward along the column direction of the pixel array between G0 and B0, then extends along the row direction of the pixel array at the top of B0, then extends downward along the column direction of the pixel array between B0 and R1, then extends along the row direction of the pixel array at the bottom of R1, then extends upward along the column direction of the pixel array between R1 and G1, then extends along the row direction of the pixel array at the top of G1, then extends downward along the column direction of the pixel array between G1 and B1, and then extends along the row direction of the pixel array at the bottom of B1, so that the G1 scan line is electrically connected to R0, G2, B0, R3, G1, and B3 of the pixel array in sequence.

[0033] When the screen display is paused at the first row of the pixel array, only the G1 scan line provides a scan signal to the pixel array, that is, only R0, B0, G1 of the first row of the pixel array and G2, R3, B3 of the second row of the pixel array will form a high level and be illuminated, and G0, R1, B1 of the first row of the pixel array and R2, B2, G3 of the second row of the pixel array will still be at a low level and will not be illuminated. At this time, only half of the pixel units in the first row of the pixel array are illuminated, and the illuminated parts of the pixel units in the first row and the illuminated parts of the pixel units in the second row are staggered with each other. The horizontal stripes are not displayed in the form of straight lines, but are displayed in the form of discontinuous lines, which can effectively eliminate the horizontal stripes caused by display pauses and thus improve the display quality.

[0034] It is understandable that in some other embodiments, the G0 scan line can be used to input scan signals to the pixel units in the odd columns of the first row of the pixel array. n The scan line is used to input scan signals to the pixel units in the even columns of the nth row of the pixel array and to the pixel units in the odd columns of the n+1th row of the pixel array. Those skilled in the art can adjust it as needed, and this application does not impose any restrictions on this.

[0035] See also Figure 2 and Figure 3 In the pixel driving architecture provided in the first embodiment of the present application, the plurality of scanning lines also include G n+1 Scan line, G n+1 The scan lines are used to input scan signals to the pixel units in the odd columns of the n+1th row of the pixel array and to the pixel units in the even columns of the n+2th row of the pixel array.

[0036] Among them, part of G n+1The scan line is set between the pixel unit of the odd column of the nth row of the pixel array and the pixel unit of the odd column of the n+1th row of the pixel array. n+1 The scan line is set between two adjacent pixel units in the n+1th row of the pixel array, and a part of G n+1 The scan line is set between the pixel units in the even columns of the n+1th row of the pixel array and the pixel units in the even columns of the n+2th row of the pixel array. n+1 The scan line inputs scan signals to the pixel units in the odd columns of the (n+1)th row of the pixel array and to the pixel units in the even columns of the (n+2)th row of the pixel array.

[0037] Exemplarily, the multiple pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, the multiple pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence, the multiple pixel units in the third row of the pixel array include R4, G4, B4, R5, G5, and B5 arranged in sequence, and the multiple pixel units in the fourth row of the pixel array include R6, G6, B6, R7, G7, and B7 arranged in sequence.

[0038] When n=1, the plurality of scan lines include a G0 scan line, a G1 scan line, and a G2 scan line. The G0 scan line is disposed at the top of the pixel unit in the first row of the pixel array and extends substantially along the row direction of the pixel array. The G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array to provide scan signals to G0, R1, and B1. The G1 scan line is electrically connected to R0, G2, B0, R3, G1, and B3 in the pixel array in sequence to provide scan signals to R0, G2, B0, R3, G1, and B3 in the pixel array. A portion of the G2 scan lines is disposed on a side of the pixel unit in the second row and odd column of the pixel array away from the pixel unit in the third row and odd column of the pixel array. Another portion of the G2 scan lines is disposed between two adjacent pixel units in the second row of the pixel array. Another portion of the G2 scan lines is disposed between a pixel unit in the second row and even column of the pixel array and a pixel unit in the third row and even column of the pixel array. The G2 scan line is electrically connected to R2, G4, B2, R5, G3, and B5 of the pixel array in sequence to provide scan signals to R2, G4, B2, R5, G3, and B5 of the pixel array.

[0039] In other words, the arrangement of the G2 scan line is as follows: the G2 scan line extends from the top of R2 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between R2 and G2, then extends at the bottom of G2 along the row direction of the pixel array, then extends upward along the column direction of the pixel array between G2 and B2, then extends at the top of B2 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between B2 and R3, then extends at the bottom of R3 along the row direction of the pixel array, then extends upward along the column direction of the pixel array between R3 and G3, then extends at the top of G3 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between G3 and B3, and then extends at the bottom of B3 along the row direction of the pixel array, so that the G2 scan line is electrically connected to R2, G4, B2, R5, G3, and B5 of the pixel array in sequence.

[0040] When the screen display is paused at the second row of the pixel array, only the G2 scan line provides a scan signal to the pixel array, that is, only R2, B2, G3 in the second row of the pixel array and G4, R5, B5 in the third row of the pixel array will form a high level and be illuminated, and G2, R3, B3 in the second row of the pixel array and R4, B4, G5 in the third row of the pixel array will still be at a low level and will not be illuminated. At this time, only half of the pixel units in the second row of the pixel array are illuminated, and the illuminated parts of the pixel units in the second row and the illuminated parts of the pixel units in the third row are staggered with each other. The horizontal stripes are not displayed in the form of straight lines, but are displayed in the form of discontinuous lines, which can effectively eliminate the horizontal stripes caused by the display pause and thus improve the display quality.

[0041] See also Figure 2 、 Figure 3 and Figure 6 , Figure 6 This is a G provided by the first embodiment of this application. n Schematic diagram of the scan line.

[0042] In a specific embodiment, G n The scanning line is wavy, G n The scanning line includes a plurality of bending structures 10. In each adjacent two bending structures 10, the end of one bending structure 10 is connected to the beginning of the other bending structure 10. Each bending structure 10 encloses two pixel areas. Two pixel units in the same row are arranged in the two pixel areas. By setting the bending structure 10, it is convenient for G n The scanning line is electrically connected to the corresponding pixel unit, which is also convenient for G n The scan lines provide scan signals to corresponding pixel units.

[0043] For example, the first row of the pixel array includes a plurality of pixel units R0, G0, B0, R1, G1, and B1, and the second row of the pixel array includes a plurality of pixel units R2, G2, B2, R3, G3, and B3, respectively. When n = 1, the G1 scan line is wavy, with the end of the first bend structure 10 of the G1 scan line connected to the beginning of the second bend structure 10 of the G1 scan line. The first bend structure 10 encloses two pixel regions accommodating R0 and G0, the second bend structure 10 encloses two pixel regions accommodating B0 and R1, and so on. Thus, the G1 scan line is electrically connected to R0, G2, B0, R3, G1, and B3.

[0044] See also Figure 2 、 Figure 3 and Figure 6 In a more specific embodiment, each bending structure 10 includes a first segment 11, a second segment 12, a third segment 13, and a fourth segment 14 connected in sequence. The first segment 11 is located on the side of the pixel unit in the odd column of the nth row of the pixel array away from the pixel unit in the odd column of the n+1th row of the pixel array. The second segment 12 is located between two adjacent pixel units in the nth row of the pixel array. The third segment 13 is located between the pixel unit in the even column of the nth row of the pixel array and the pixel unit in the even column of the n+1th row of the pixel array. The fourth segment 14 is located between another two adjacent pixel units in the nth row of the pixel array. By the segmented arrangement of the bending structure 10 and the position design of each segment, G n The scanning line is electrically connected to the corresponding pixel unit, which is also convenient for G n The scan lines provide scan signals to corresponding pixel units.

[0045] For example, the plurality of pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1, which are arranged in sequence, and the plurality of pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3, which are arranged in sequence. When n=1, in the first fold structure 10 of the G1 scan line, the first segment 11 is located at the top of R0 and extends along the row direction of the pixel array, the second segment 12 is located between R0 and G0 and extends downward along the column direction of the pixel array, the third segment 13 is located between G0 and G2 and extends along the row direction of the pixel array, and the fourth segment 14 is located between G0 and B0 and extends upward along the column direction of the pixel array. In the second fold structure 10 of the G1 scan line, the first segment 11 is located at the top of B0 and extends along the row direction of the pixel array. The second segment 12 is located between B0 and R1 and extends downward along the column direction of the pixel array. The third segment 13 is located between R1 and R3 and extends along the row direction of the pixel array. The fourth segment 14 is located between R1 and G1 and extends upward along the column direction of the pixel array, and so on. Thus, by segmenting and arranging the fold structure 10, the G1 scan line is electrically connected to R0, G2, B0, R3, G1, and B3, and it is also convenient for the G1 scan line to provide scan signals to R0, G2, B0, R3, G1, and B3.

[0046] See also Figure 4 and Figure 5 The pixel driving architecture provided in the second embodiment of the present application is substantially the same as the pixel driving architecture provided in the first embodiment of the present application. The difference lies in the design of the scan lines of the pixel driving architecture provided in the second embodiment of the present application. In the pixel driving architecture provided in the second embodiment of the present application, The plurality of scan lines include a G0 scan line and a G1 scan line. The G0 scan line extends along the row direction of the pixel array. The G0 scan line is disposed on a side of the pixel units in the first row of the pixel array that is away from the pixel units in the second row of the pixel array. The G0 scan line is electrically connected to the pixel units in the even-numbered columns of the first row of the pixel array. The G0 scan line is used to input scan signals to the pixel units in the even-numbered columns of the first row of the pixel array. The G1 scan line is electrically connected to the pixel units in the even-numbered columns of the second row of the pixel array. The G1 scan line is used to input scan signals to the pixel units in the even-numbered columns of the second row of the pixel array.

[0047] Part of the G1 scan lines is arranged between the pixel units in the odd-numbered columns of the first row of the pixel array and the G0 scan line, part of the G1 scan lines is arranged between two adjacent pixel units in the first row of the pixel array, and part of the G1 scan lines is arranged between the pixel units in the even-numbered columns of the first row of the pixel array and the pixel units in the even-numbered columns of the second row of the pixel array. Thus, the G1 scan lines input scan signals to the pixel units in the even-numbered columns of the second row of the pixel array.

[0048] For example, the plurality of pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, and the plurality of pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence. The G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array to provide a scan signal to G0, R1, and B1 in the first row of the pixel array. The G1 scan line is electrically connected to G2, R3, and B3 in the second row of the pixel array to provide a scan signal to G2, R3, and B3 in the second row of the pixel array.

[0049] In other words, the arrangement of the G1 scan line is as follows: the G1 scan line extends from the top of R0 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between R0 and G0, then extends along the row direction of the pixel array at the bottom of G0, then extends upward along the column direction of the pixel array between G0 and B0, then extends along the row direction of the pixel array at the top of B0, then extends downward along the column direction of the pixel array between B0 and R1, then extends along the row direction of the pixel array at the bottom of R1, then extends upward along the column direction of the pixel array between R1 and G1, then extends along the row direction of the pixel array at the top of G1, then extends downward along the column direction of the pixel array between G1 and B1, and then extends along the row direction of the pixel array at the bottom of B1, so that the G1 scan line is electrically connected to G2, R3, and B3 of the pixel array in sequence.

[0050] When the screen display is paused at the first row of the pixel array, only the G0 scan line provides a scan signal to the pixel array, that is, only G0, R1, and B1 of the first row of the pixel array will form a high level and be illuminated, while R0, B0, and G1 will still be low and will not be illuminated. At this time, only half of the pixel units in the first row of the pixel array are illuminated, and the horizontal stripes are not displayed in the form of straight lines, but in the form of discontinuous lines. This can effectively eliminate the horizontal stripes caused by the display pause, thereby improving the display quality.

[0051] See also Figure 4 and Figure 5 In the pixel driving architecture provided in the second embodiment of the present application, the plurality of scanning lines also include G n+1 Scan line, G n+1 The scan line is used to input scan signals to the pixel units in the odd columns of the nth row of the pixel array and to the pixel units in the even columns of the n+2th row of the pixel array. Where n≥1, and n is an integer. Thus, in order to facilitate G n+1 The scan line inputs scan signals to the pixel units in the odd columns of the nth row of the pixel array and to the pixel units in the even columns of the (n+2)th row of the pixel array.

[0053] When n=1, the plurality of scan lines include a G0 scan line, a G1 scan line, and a G2 scan line. The G0 scan line is disposed at the top of the pixel unit in the first row of the pixel array and extends substantially along the row direction of the pixel array. The G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array to provide scan signals to G0, R1, and B1. The G1 scan line is electrically connected to G2, R3, and B3 in the pixel array in sequence to provide scan signals to G2, R3, and B3 in the pixel array. A portion of the G2 scan lines is disposed between the pixel units in the odd columns of the first row of the pixel array and the G1 scan line. Another portion of the G2 scan lines is disposed between two adjacent pixel units in the first row of the pixel array and between two adjacent pixel units in the second row. Another portion of the G2 scan lines is disposed between the pixel units in the even columns of the second row of the pixel array and the pixel units in the even columns of the third row of the pixel array. The G2 scan line is electrically connected to R0, G4, B0, R5, G1, and B5 of the pixel array in sequence to provide scan signals to R0, G4, B0, R5, G1, and B5 of the pixel array.

[0054] In other words, the G2 scan line is arranged as follows: the G2 scan line extends from the top of R0 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between R0 and G0 and R2 and G2, then extends along the row direction of the pixel array at the bottom of G2, then extends upward along the column direction of the pixel array between G2 and B2 and G0 and B0, then extends along the row direction of the pixel array at the top of B0, then extends downward along the column direction of the pixel array between B0 and R1 and B2 and R3, then extends along the row direction of the pixel array at the bottom of R3, then extends upward along the column direction of the pixel array between R3 and G3 and R1 and G1, then extends along the row direction of the pixel array at the top of G1, then extends downward along the column direction of the pixel array between G1 and B1 and G3 and B3, and then extends along the row direction of the pixel array at the bottom of B3, so that the G2 scan line is electrically connected to R0, G4, B0, R5, G1, and B5 of the pixel array in sequence.

[0055] When the image display is paused at the first row of the pixel array, only the G2 scan line provides a scan signal to the pixel array, that is, R0, B0, G1 of the first row of the pixel array and G4, R5, B5 of the third row of the pixel array will form a high level and be illuminated, while G0, R1, B1 of the first row of the pixel array and G4, B4, G5 of the third row of the pixel array will remain at a low level and will not be illuminated. At this time, only half of the pixel units in the first row of the pixel array and the pixel units in the third row are illuminated, and the illuminated portions of the pixel units in the first row and the illuminated portions of the pixel units in the third row are staggered. The horizontal stripes are not displayed in the form of straight lines, but in the form of discontinuous lines, which can effectively eliminate the horizontal stripes caused by the display pause and thus improve the display quality. Moreover, the pixel driving architecture provided in the second embodiment of the present application has a larger distance between the discontinuous lines of the horizontal stripes than the distance between the discontinuous lines of the horizontal stripes provided in the pixel driving architecture provided in the first embodiment of the present application, which can further reduce the visibility of the horizontal stripes and help further improve the display quality.

In each adjacent two bending structures 10, the end of one bending structure 10 is connected to the beginning of another bending structure 10. By setting the bending structure 10, it is convenient for G n+1 The scanning line is electrically connected to the corresponding pixel unit, which is also convenient for G n+1 The scan lines provide scan signals to corresponding pixel units.

[0058] For example, the plurality of pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence; the plurality of pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence; and the plurality of pixel units in the third row of the pixel array include R4, G4, B4, R5, G5, and B5 arranged in sequence. When n=1, the G2 scan line is wavy, with the end of the first bend structure 10 of the G2 scan line connected to the beginning of the second bend structure 10 of the G2 scan line, and so on. Thus, the G2 scan line is electrically connected to R0, G2, B0, R3, G1, and B3.

[0059] See also Figure 4 、 Figure 5 and Figure 7In a more specific embodiment, each bending structure 10 includes a first segment 11, a second segment 12, a third segment 13, and a fourth segment 14 connected in sequence. The first segment 11 is located on the side of the pixel unit in the odd column of the nth row of the pixel array away from the pixel unit in the odd column of the n+1th row of the pixel array. The second segment 12 is located between two adjacent pixel units in the nth row of the pixel array and two adjacent pixel units in the n+1th row of the pixel array. The third segment 13 is located between the pixel unit in the even column of the n+1th row of the pixel array and the pixel unit in the even column of the n+2th row of the pixel array. The fourth segment 14 is located between another two adjacent pixel units in the nth row of the pixel array and another two adjacent pixel units in the n+1th row of the pixel array. By the segmented arrangement of the bending structure 10 and the position design of each segment, it is convenient for G n+1 The scanning line is electrically connected to the corresponding pixel unit, which is also convenient for G n+1 The scan lines provide scan signals to corresponding pixel units.

[0060] For example, the plurality of pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, the plurality of pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence, and the plurality of pixel units in the third row of the pixel array include R4, G4, B4, R5, G5, and B5 arranged in sequence. When n=1, in the first fold structure 10 of the G2 scan line, the first segment 11 is located at the top of R0 and extends along the row direction of the pixel array, the second segment 12 is located between R0 and G0 and between R2 and G2 and extends downward along the column direction of the pixel array, the third segment 13 is located between G2 and G4 and extends along the row direction of the pixel array, and the fourth segment 14 is located between G0 and B0 and between G2 and B2 and extends upward along the column direction of the pixel array.

The second segment 12 is located between B0 and R1 and between B2 and R3 and extends downward along the column direction of the pixel array. The third segment 13 is located between R3 and R5 and extends along the row direction of the pixel array. The fourth segment 14 is located between R1 and G1 and between R3 and G3 and extends upward along the column direction of the pixel array, and so on. Thus, by segmenting and arranging the fold structure 10, the G2 scan line is electrically connected to R0, G4, B0, R5, G1, and B5, and it is also convenient for the G2 scan line to provide scan signals to R0, G4, B0, R5, G1, and B5.

[0061] See also Figure 4 and Figure 5 In the pixel driving architecture provided in the second embodiment of the present application, the plurality of scanning lines also include G n+2 Scan line, G n+2The scan line is used to input scan signals to the pixel units in the odd columns of the n+1th row of the pixel array and to the pixel units in the even columns of the n+3th row of the pixel array. n+2 The scan line inputs scan signals to the pixel units in the odd columns of the (n+1)th row of the pixel array and to the pixel units in the even columns of the (n+3)th row of the pixel array.

[0062] Exemplarily, the multiple pixel units in the first row of the pixel array include R0, G0, B0, R1, G1, and B1 arranged in sequence, the multiple pixel units in the second row of the pixel array include R2, G2, B2, R3, G3, and B3 arranged in sequence, the multiple pixel units in the third row of the pixel array include R4, G4, B4, R5, G5, and B5 arranged in sequence, and the multiple pixel units in the fourth row of the pixel array include R6, G6, B6, R7, G7, and B7 arranged in sequence.

[0063] When n=1, the plurality of scan lines include a G0 scan line, a G1 scan line, a G2 scan line, and a G3 scan line. The G0 scan line is disposed at the top of the pixel unit in the first row of the pixel array and extends substantially along the row direction of the pixel array. The G0 scan line is electrically connected to G0, R1, and B1 in the first row of the pixel array to provide a scan signal to G0, R1, and B1. The G1 scan line is electrically connected to G2, R3, and B3 in the pixel array in sequence to provide a scan signal to G2, R3, and B3 in the pixel array. The G2 scan line is electrically connected to R0, G4, B0, R5, G1, and B5 in the pixel array in sequence to provide a scan signal to R0, G4, B0, R5, G1, and B5 in the pixel array. A portion of the G3 scan lines is arranged between the pixel cells in the odd columns of the first row of the pixel array and the pixel cells in the odd columns of the second row of the pixel array. Another portion of the G3 scan lines is arranged between two adjacent pixel cells in the second row of the pixel array and between two adjacent pixel cells in the third row of the pixel array. Another portion of the G3 scan lines is arranged between the pixel cells in the even columns of the third row of the pixel array and the pixel cells in the even columns of the fourth row of the pixel array. The G3 scan lines are electrically connected to R2, G6, B2, R7, G3, and B7 of the pixel array in sequence to provide scan signals to R2, G6, B2, R7, G3, and B7 of the pixel array.

[0064] In other words, the arrangement of the G2 scan line is as follows: the G3 scan line extends from the top of R2 along the row direction of the pixel array, then extends downward along the column direction of the pixel array between R2 and G2 and R4 and G4, then extends along the row direction of the pixel array at the bottom of G4, then extends upward along the column direction of the pixel array between G4 and B4 and G2 and B2, then extends along the row direction of the pixel array at the top of B2, then extends downward along the column direction of the pixel array between B2 and R3 and B4 and R5, then extends along the row direction of the pixel array at the bottom of R5, then extends upward along the column direction of the pixel array between R5 and G5 and R3 and G3, then extends along the row direction of the pixel array at the top of G3, then extends downward along the column direction of the pixel array between G3 and B3 and G5 and B5, and then extends along the row direction of the pixel array at the bottom of B5, so that the G2 scan line is electrically connected to R2, G6, B2, R7, G3, and B7 of the pixel array in sequence.

[0065] When the image display is paused at the second row of the pixel array, only the G3 scan line provides a scan signal to the pixel array, that is, R2, B2, G3 of the second row of the pixel array and G6, R7, B7 of the fourth row of the pixel array will form a high level and be illuminated, while G2, R3, B3 of the second row of the pixel array and G6, B6, G6 of the fourth row of the pixel array will remain at a low level and will not be illuminated. At this time, only half of the pixel units in the second row of the pixel array and the pixel units in the fourth row are illuminated, and the illuminated portions of the pixel units in the second row and the illuminated portions of the pixel units in the fourth row are staggered. The horizontal stripes are not displayed in the form of straight lines, but in the form of discontinuous lines, which can effectively eliminate the horizontal stripes caused by the display pause and thus improve the display quality. Moreover, the pixel driving architecture provided in the second embodiment of the present application has a larger distance between the discontinuous lines of the horizontal stripes than the distance between the discontinuous lines of the horizontal stripes provided in the pixel driving architecture provided in the first embodiment of the present application, which can further reduce the visibility of the horizontal stripes and help further improve the display quality.

[0066] See also Figures 8 to 10 , Figure 8 This is a timing control logic diagram of a pixel driving method provided by an embodiment of the present application. Figure 9 is a timing diagram of a pixel driving method provided by an embodiment of the present application in the nth frame, Figure 10 This is a timing diagram of a pixel driving method provided by an embodiment of the present application in the (n+1)th frame.

[0067] The pixel driving method provided in this application is used in the above-mentioned pixel driving architecture and includes the following steps: When it is determined that the next frame is an odd-numbered frame, the timing controller controls the scan lines to input scan signals to the pixel array according to the first mode.

[0068] When it is determined that the next frame is an even frame, the timing controller controls the scan lines to input scan signals to the pixel array according to the second mode.

[0069] The first mode is different from the second mode. The number of rows of scan lines controlled by the timing controller to input scan signals to the pixel array according to the first mode is different from the number of rows of scan lines controlled by the timing controller to input scan signals to the pixel array according to the second mode.

[0070] Specifically, first, the current frame number is counted by the frame counter; then, the next frame is determined by the timing controller. Figure 9 As shown, if the timing controller determines that the next frame is an odd frame, it further controls the scan lines to input scan signals to the pixel array in the first mode, so that the position where the horizontal stripes occur is in the display area where the n-th row of pixel units in the pixel array are located; in other words, the timing controller controls the scan lines to input scan signals to the pixel array in the first mode, that is, controls the scan lines of the first n rows to input scan signals to the first n rows of pixel units in the pixel array, and at this time, the position where the horizontal stripes occur is in the display area where the n-th row of pixel units in the pixel array are located. Figure 10 As shown, if the timing controller determines that the next frame is an even frame, it further controls the scan lines to input scan signals to the pixel array in the second mode, so that the position where the horizontal stripes occur is in the display area where the pixel units in the n+1th row of the pixel array are located; in other words, the timing controller controls the scan lines to input scan signals to the pixel array in accordance with the second mode, that is, controls the scan lines in the first n+1 rows to input scan signals to the pixel units in the first n+1 rows of the pixel array, and at this time, the position where the horizontal stripes occur is in the display area where the pixel units in the n+1th row of the pixel array are located.

[0071] Therefore, by adjusting the position of the horizontal streaks in different frames, the positions of the streaks are continuously changing, ultimately making them less visible and optimizing image quality. If this is reflected in the touch action, the position of the streaks will change in real time due to the real-time changes in the touch action, which can also reduce the impact of the streaks on image quality.

[0072] See also Figure 7 and Figure 8For example, the pixel driving method provided by the present application can cyclically adjust the paused display row of the pixel array when a touch action occurs. For example, when the nth frame is displayed, the touch action occurs after the 500th row display is updated, and horizontal stripes will also appear in the 500th row display area; when the n+1th frame is displayed, the touch action occurs at the 501st row, or the 502nd row (the specific number of rows can be adjusted), so the touch horizontal stripes will also change accordingly; because the touch action changes in real time in different frames, the position of the horizontal stripes will also change in real time. When the user watches through the human eye, the position of the horizontal stripes continues to change, so the impact of the horizontal stripes on the image quality will be further reduced. Among them, G n is the Gate control signal, D n is the source control signal of Date, R X is the touch signal, t1 is the touch time; in the nth frame, the screen update is paused at the Gn line, and in the n+1th frame, the screen update is paused at the Gn+1 line.

[0073] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
