[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] Embodiment 1

[0030] In order to solve the problem in the related art that the display panel displays a low-resolution image to be displayed and the display effect is poor, please refer to Figure 1 , Figure 1 A method for driving a display panel provided in an embodiment of the present application includes:

[0031] S101, when scanning the Nth pixel row, the data line outputs a first data signal to charge the pixel capacitor of the Nth pixel row through the first data signal, and N is an odd number;

[0032] S102, when the duration of the data line outputting the first data signal reaches a preset duration, scanning the N+1th pixel row, the data line outputting the first data signal to charge the pixel capacitor of the Nth pixel row through the first data signal, and at the same time, charging the pixel capacitor of the N+1th pixel row through the first data signal;

[0033] S103, scanning the N+2th pixel row, the data line outputs a second data signal, so as to charge the N+2th pixel row through the second data signal, and at the same time charge the pixel capacitor of the N+1th pixel row through the second data signal, so that the pixel capacitor of the N+1th pixel row includes the first data signal and the second data signal.

[0034] The driving method of the display panel is applied to a display panel, the display panel comprises a plurality of sub-pixels arranged in an array, each sub-pixel corresponds to a pixel capacitor, the plurality of sub-pixels arranged in an array comprises a plurality of pixel rows and a plurality of pixel columns; the display panel further comprises: a plurality of rows of scan lines and a plurality of columns of data lines, each row of the scan lines corresponds to at least one of the pixel rows, each row of the scan lines is used to scan the corresponding pixel row, and each of the data lines corresponds to at least one of the pixel columns;

[0035] It can be understood that when the scan line scans the pixel row corresponding to the scan line, the thin film transistor in the pixel row corresponding to the scan line is turned on, so that the data signal output by the data line can charge the pixel capacitor of each sub-pixel in the pixel row; similarly, when the scan line does not scan the pixel row corresponding to the scan line, the thin film transistor in the pixel row corresponding to the scan line is turned off, so that the data signal output by the data line cannot charge the pixel capacitor of each sub-pixel in the pixel row. It can be understood that each thin film transistor described in this embodiment can be a P-type thin film transistor (P-type thin-film-transistor, P-type TFT) or an N-type thin film transistor (N-type thin-film-transistor, N-type TFT), and this embodiment does not limit the type of thin film transistor; at the same time, the thin film transistor provided in this embodiment can be made using a thin film transistor (TFT) process technology of low temperature polycrystalline silicon (LTPS), amorphous silicon (a-Si) or amorphous indium gallium tin metal oxide (a-IGZO), but is not limited thereto.

[0036] It should be understood that there are multiple pixel groups in each pixel row, each pixel group includes at least three different sub-pixels, each sub-pixel corresponds to a data line, and the data signal output by each data line is different; for example, the Nth pixel row has N pixel groups, such as Figure 2As shown, each pixel group includes a red sub-pixel R1, a green sub-pixel G1 and a blue sub-pixel G2. When the Nth pixel row is scanned, the data line outputs a first data signal, and the data line corresponding to the red sub-pixel R1 outputs a corresponding R1 first data signal, the data line corresponding to the green sub-pixel G1 outputs a corresponding R2 first data signal, and the data line corresponding to the blue sub-pixel B1 outputs a corresponding B2 first data signal; it can be understood that, in some examples, a pixel group includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a white sub-pixel W, and the corresponding data lines output R / B / G / W data signals respectively; in some examples, a pixel group includes a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B, and a yellow sub-pixel Y, and the corresponding data lines output R / B / G / Y data signals respectively; and it can be understood that the data lines output a data signal at the same time, for example, the data line outputs the first data signal at the first time, then at this time, the data line will not output the second data signal, and the data line outputs the second data signal at the second time, then at this time, the data line will not output the first data signal.

[0037] It should be understood that if N is an odd number, the Nth pixel row is an odd pixel row, the N+1th pixel row is an even pixel row, the N+2th pixel row is an odd pixel row, and the Nth pixel row, the N+1th pixel row and the N+2th pixel row are three pixel rows arranged in sequence, and so on, the N+3th pixel row is an even pixel row; in some examples of the present embodiment, when the Nth pixel scan row ends, scanning of the N+2th pixel row begins; when scanning of the N+1th pixel row ends, scanning of the N+3th pixel row begins.

[0038] It can be understood that the scanning time of each pixel row is fixed, for example, the scanning time of each pixel row is N, and the time for the data line to output each data signal is also fixed, and the time for the data line to output each data signal is the same as the scanning time of each pixel row, for example, the time for the data line to output any data signal is N; in addition, the scanning time of the N+1th pixel row partially overlaps with the scanning time of the Nth pixel row, and the scanning time of the N+1th pixel row partially overlaps with the scanning time of the N+2th pixel row, for example: the scanning time of the Nth pixel row is the first time period, and the scanning time of the N+1th pixel row is the second time period. The scanning time of the N+2th pixel row is the second time period, and the scanning time of the N+2th pixel row is the third time period, then the second time period overlaps with the first time period, and the second time period overlaps with the third time period. Specifically, taking the 1st second to the 7th second as an example, the first time period is 1-4 seconds, the second time period is 2-5 seconds, and the third time period is 4-7 seconds. At this time, the second time period partially overlaps with the first time period, and the second time period partially overlaps with the third time period. It should be understood that the above 1-7 seconds is only used for illustration, and is not used to limit the first time period to 1-4 seconds, the second time period to 2-5 seconds, and the third time period to 4-7 seconds.

[0039] It should be understood that in step S102, when the duration of the data line outputting the first data signal reaches a preset duration, the preset duration is a preset duration, and how to set the duration will be described in detail later. It should be understood that the preset duration is less than the total duration of the data line outputting the first data signal. For example, taking the total duration of the data line outputting the first data signal as N as an example, the preset duration is a duration greater than 0 and less than N.

[0040] The driving method of the display panel provided in the present embodiment turns on the N+1th pixel row for scanning when the duration of the data line outputting the first data signal reaches a preset duration, and charges the pixel capacitor of the N+1th pixel row, so that the pixel capacitor of each sub-pixel in the N+1th pixel row includes the first data signal, and then when the data line outputs the second data signal to charge the pixel capacitor of the N+2th pixel row, the pixel capacitor of the N+1th pixel row is charged by the second data signal, so that the pixel capacitor of each sub-pixel in the N+1th pixel row includes the first data signal and the second data signal, and thus the display effect of the N+1th pixel row is between that of the N pixel row and the N+2 pixel row, thereby achieving the effect of adding one line of display data, and by adding one line of display data, the resolution is improved on the basis of displaying the original image on the display panel.

[0041] In some examples of the present embodiment, when scanning the Nth pixel row, the data line outputs the first data signal to charge the pixel capacitor of the Nth pixel row, including: when starting to scan the Nth pixel row, recording the scanning time of scanning the Nth pixel row; when the scanning time reaches the preset anti-mischarge time, the data line outputs the first data signal to charge the pixel capacitor of the Nth pixel row. It should be understood that when scanning the pixel row, the thin film transistor of the pixel row is gradually turned on and off, rather than suddenly turned on or off. Therefore, if the data line directly outputs the first data signal when scanning the Nth pixel row, and the data line directly outputs the second data signal when stopping scanning the Nth pixel row, the second data signal may be mistakenly charged into the pixel capacitor of the Nth pixel row, resulting in affecting the display effect of the Nth pixel row. Therefore, in the driving method of the display panel provided in the present embodiment, when the scanning time reaches the preset anti-error charging time, the data line outputs the first data signal to charge the pixel capacitor of the Nth pixel row. After the preset anti-error charging time is reached after the scanning starts, the data line outputs the first data signal. Before the first data signal output by the data line ends, the Nth pixel row has finished scanning and is no longer being charged. When the data line outputs the second data signal, the Nth pixel row has finished scanning and is no longer being charged, thereby ensuring that the second data signal will not be charged into the pixel capacitor of the Nth pixel row, thereby achieving the effect of not affecting the display effect of the Nth pixel row, thereby improving the display effect of the display panel.

[0042] Continuing with the above example, for example, Figure 3 As shown, when N is 1, the N-th pixel row corresponds to the CLK1 scanning signal, the N+1-th pixel row corresponds to the CLK2 scanning signal, and so on; the scanning line CLK1 corresponding to the first pixel row transmits a high-level scanning signal, and when scanning the first pixel row, the scanning time h for scanning the N-th pixel row is recorded, and when h reaches the preset anti-mischarge time, the data line starts to output the first data signal Data1 to charge the pixel capacitor of the first pixel row, and then when CLK1 stops outputting the high-level scanning signal, the data line will continue to output the first data signal for h time, and then output the second data signal Data2, so as to avoid the problem that the data signal mistakenly charges the pixel capacitor of the first pixel row when outputting the second data signal Data2, thereby improving the display effect of the first pixel row.

[0043] It can be understood that the above-mentioned preset anti-error charging time is a time set by relevant personnel according to actual needs, wherein the value range of the preset anti-error charging time is: 0<preset anti-error charging time<half of the total scanning time.

[0044] It should be understood that the above scheme is to make the scanning signal time of the Nth pixel row unchanged, and the output time of the first data signal corresponding to the Nth pixel row is delayed. In some examples, it can also be achieved by obtaining the initial time when the data line outputs the first data signal, and then pre-setting the anti-error charging time for the scanning signal of the Nth pixel row according to the initial time, so that the Nth pixel row starts scanning with the pre-set anti-error charging time on the basis of the initial time, and ends the scanning with the pre-set anti-error charging time while the first data signal is still being output, so that when the first data signal output by the data line has not yet ended, the Nth pixel row has ended scanning and is no longer charging, and when the data line outputs the second data signal, the Nth pixel row has ended scanning and stopped charging, thereby ensuring that the second data signal will not be charged into the pixel capacitor of the Nth pixel row, thereby achieving the effect of not affecting the display effect of the Nth pixel row, thereby improving the display effect of the display panel.

[0045] In some examples of this embodiment, when scanning the Nth pixel row, the data line outputs the first data signal to charge the pixel capacitor of the Nth pixel row, including: when starting to scan the Nth pixel row, the data line directly outputs the first data signal to charge the pixel capacitor of the Nth pixel row. Specifically, for example, Figure 4 As shown, when N is 1, the N-th pixel row corresponds to the CLK1 scanning signal, the N+1-th pixel row corresponds to the CLK2 scanning signal, and so on; the scanning line CLK1 corresponding to the first pixel row transmits a high-level scanning signal. When scanning the first pixel row, the data line directly starts to output the first data signal Data1 to charge the pixel capacitor of the first pixel row. When CLK1 stops outputting the high-level scanning signal, the data line stops outputting the first data signal and starts outputting the second data signal Data2.

[0046] In some examples of the present embodiment, when the duration for the data line to output the first data signal reaches a preset duration, before scanning the N+1th pixel row, the method further includes: determining the total output duration for the data line to output the first data signal; determining the preset duration based on the total output duration, so that the charging duration of the pixel capacitor of the N+1th pixel row by the first data signal is higher than the charging duration of the pixel capacitor of the N+1th pixel row by the second data signal, that is, by setting a preset duration, the duration for starting to scan the N+1th pixel row is controlled according to the preset duration, so that in the pixel capacitor of the N+1th pixel row, the charging duration of the first data signal is higher than the charging duration of the second data signal, thereby avoiding the problem that the pixel capacitor of the N+1th pixel row is charged for too long by the second data signal, resulting in the data in the pixel capacitor of the N+1th pixel row completely tending towards the second data signal.

[0047] In some examples of this embodiment, determining the preset duration according to the total output duration includes: determining a value range of the preset duration according to the total output duration; determining a duration ratio of the first data signal and the second data signal for charging the pixel capacitor of the N+1th pixel row, and determining the preset duration according to the duration ratio and the value range. Figure 3 As shown, assuming that the preset duration is h1, and the total output duration of the data line output data signal is n, then the charging duration of the pixels of the N+1th pixel row by the first data signal is n-h1, and the charging duration of the pixels of the N+1th pixel row by the second data signal is h1. At this time, in order to make the charging duration n-h1 of the pixel capacitor of the N+1th pixel row by the first data signal higher than the charging duration h1 of the pixel capacitor of the N+1th pixel row by the second data signal, that is, satisfying n-h1>h1, simplifying the above formula, it can be obtained that h1<N / 2, that is, at this time, the preset charging duration h1 needs to satisfy 0

[0048] ​Continuing with the above example, if the preset duration calculated according to the duration ratio is within the value range of the preset duration determined according to the total output duration, then the preset duration is determined to be available, otherwise an error is reported; for example, according to the duration ratio, the duration for the first data signal to charge the pixel capacitor of the N+1th pixel row is h1 is 7 / 10*n, then the preset duration h1 is N-7 / 10*n=3 / 10*n, at this time h1 satisfies 0

[0049] In some examples of this embodiment, after the pixel capacitors of the N+1th pixel row are charged by the second data signal, the method further includes: when the charging time of the pixel capacitors of the N+1th pixel row charged by the second data signal reaches the preset time, stopping charging the pixel capacitors of the N+1th pixel row. Figure 3 As shown, assuming that the preset time length is h1, when the charging time length of the N+1th pixel row when the data line outputs the second data signal reaches h1, charging of the pixel capacitor of the N+1th pixel row is stopped.

[0050] ​The driving method of the display panel provided in the present embodiment includes: when scanning the Nth pixel row, the data line outputs a first data signal to charge the pixel capacitor of the Nth pixel row through the first data signal, and N is an odd number; when the duration for which the data line outputs the first data signal reaches a preset duration, scanning the N+1th pixel row, the data line outputs the first data signal to charge the pixel capacitor of the Nth pixel row through the first data signal, and at the same time charges the pixel capacitor of the N+1th pixel row through the first data signal; scanning the N+2th pixel row, the data line outputs a second data signal to charge the pixel capacitor of the N+2th pixel row through the second data signal, and at the same time charges the pixel capacitor of the N+1th pixel row through the second data signal, so that the pixel capacitor of the N+1th pixel row includes the first data signal. According to the first data signal and the second data signal, when the duration of the data line outputting the first data signal reaches the preset duration, the N+1th pixel row is turned on for scanning, and the pixel capacitor of the N+1th pixel row is charged, so that the pixel capacitor of each sub-pixel in the N+1th pixel row includes the first data signal, and then when the data line outputs the second data signal to charge the pixel capacitor of the N+2th pixel row, the pixel capacitor of the N+1th pixel row is charged by the second data signal, so that the pixel capacitor of each sub-pixel in the N+1th pixel row includes the first data signal and the second data signal, and thus the display effect of the N+1th pixel row is between the N pixel row and the N+2 pixel row, so as to achieve the effect of adding one line of display data. By adding one line of display data, the resolution is improved on the basis of displaying the original image on the display panel, thereby avoiding the problem that the display panel displays a low-resolution image to be displayed and the display effect is poor.

[0051] Embodiment 2

[0052] In order to better understand the present invention, this embodiment provides a more specific example to illustrate the present invention.

[0053] The present embodiment provides a driving method for a display panel, by adjusting the timing, the TFT of the first pixel row is turned on while the pixel capacitor of the first pixel row is charged, before the charging of the first pixel row is completed, the TFT of the second pixel row is turned on, and the pixel capacitor of the second pixel row is also charged with the data of the first pixel row; after the charging of the first pixel row is completed, the TFT of the first pixel row is turned off, and the TFT of the third pixel row is turned on at the same time, at this time the TFT of the second pixel row is not turned off yet, and the data of the third pixel row is also charged into the second pixel row, by controlling the time for the pixels of the second pixel row to be charged with the data signals corresponding to the first pixel row and the third pixel row, it can be achieved that the display data included in the pixel capacitor of the second pixel row is between the first row and the third row, thereby achieving the effect of adding one row of display data.

[0054] Specifically, the driving method of the display panel provided in this embodiment includes the following steps:

[0055] a. Figure 5 As shown, when the scanning signal gate1 corresponding to the first pixel row is at a high level, the data lines S1 / S2 / S3 will respectively send the first data signals R1 / G1 / B1 to the pixels of the first pixel row to charge the pixel capacitors of the first pixel row.

[0056] b. While the first pixel row is being charged, the scanning signal gate1&2 corresponding to the second pixel row will rise from a low level to a high level. At this time, S1 / S2 / S3 is still sending the first data signal to the first pixel row for charging, so that the second pixel row will also be charged with the data of R1 / G1 / B1.

[0057] c. When the first pixel row is fully charged, the scanning signal gate1 corresponding to the first pixel row will drop from a high level to a low level, and the pixel capacitor of the first pixel row will be fully charged. At the same time, the scanning signal gate2 corresponding to the third pixel row will rise from a low level to a high level, and S1 / S2 / S3 will respectively send the second data signal of R2 / G2 / B2 to the pixel capacitor corresponding to the sub-pixel of the third pixel row to charge the pixel capacitor of the third pixel row. Because the scanning signal gate1&2 corresponding to the second pixel row is still at a high level at this time, the second pixel row will also be charged with the second data signal of R2 / G2 / B2 at this time.

[0058] d. When the scanning signal gate1&2 corresponding to the second pixel row drops from a high level to a low level, the data charged by the pixels in the second row is the neutralization effect of the data charged by the pixels in the first pixel row and the third pixel row.

[0059] e. Similarly, when the scanning signal gate1&2 corresponding to the second pixel row drops from high level to low level, the scanning signal gate2&3 corresponding to the fourth pixel row will rise from low level to high level, and the fourth pixel row will be charged with the data signals of the third pixel row and the fifth pixel row. The charging data of the first five rows is as follows Figure 6 shown.

[0060] f. Similarly, all even pixel rows except the last row will be charged with the display data (data signal) of the two adjacent odd pixel rows, and the last even pixel row will only be charged with the display data (data signal) of the second to last odd row.

[0061] Through the display panel driving method provided in this example, taking UHD 60Hz as an example, the front end inputs 4K2K 60Hz data of the image to be displayed. According to the above display panel driving method, a line of display data is added, and finally the display panel can actually display 4K4K 60Hz data, thereby achieving the effect of improving the resolution.

[0062] Embodiment 3

[0063] Based on the same concept, this embodiment also provides a display driving device, such as Figure 7 As shown, the display driving device includes: a scan driving module 3 and a data driving module 4; the scan driving module 3 is connected to a plurality of scan lines 1, and each scan line 1 corresponds to a pixel row, and the data driving module 4 is connected to the data line 2, wherein:

[0064] The scanning driving module 3 is used to output a scanning signal to scan the Nth pixel row in a first time period, output a scanning signal to scan the N+1th pixel row in a second time period, and output a scanning signal to scan the N+2th pixel row in a third time period, wherein the first time period, the second time period and the third time period are different time periods, and N is an odd number;

[0065] The data driving module 4 is used for outputting a first data signal through the data line 2 when the scanning driving module 3 scans the N-th pixel row, so as to charge the pixel capacitor of the N-th pixel row through the first data signal;

[0066] The data driving module 4 is further configured to charge the pixel capacitor of the N+1th pixel row through the first data signal when the scanning driving module 3 scans the N+1th pixel row;

[0067] The data driving module 4 is also used to output a second data signal through the data line 2 when the scanning driving module 3 scans the N+2 pixel row, so as to charge the N+2 pixel row through the second data signal, and to charge the pixel capacitor of the N+1 pixel row through the second data signal, so that the pixel capacitor of the N+1 pixel row includes the first data signal and the second data signal.

[0068] It should be understood that if N is an odd number, the Nth pixel row is an odd pixel row, the N+1th pixel row is an even pixel row, the N+2th pixel row is an odd pixel row, and the Nth pixel row, the N+1th pixel row and the N+2th pixel row are three pixel rows arranged in sequence, and so on, the N+3th pixel row is an even pixel row; in some examples of the present embodiment, when the Nth pixel scan row ends, scanning of the N+2th pixel row begins; when scanning of the N+1th pixel row ends, scanning of the N+3th pixel row begins.

[0069] It can be understood that the scanning time of each pixel row is fixed, for example, the scanning time of each pixel row is N, and the time for data line 2 to output each data signal is also fixed, and the time for data line 2 to output each data signal is the same as the scanning time of each pixel row, for example, the time for data line 2 to output any data signal is N; in addition, the scanning time of the N+1th pixel row partially overlaps with the scanning time of the Nth pixel row, and the scanning time of the N+1th pixel row partially overlaps with the scanning time of the N+2th pixel row, for example: the scanning time of the Nth pixel row is the first time period, and the scanning time of the N+1th pixel row is the second time period. The scanning time is the second time period, and the scanning time of the N+2th pixel row is the third time period, then the second time period overlaps with the first time period, and the second time period overlaps with the third time period. Specifically, taking the 1st second to the 7th second as an example, the first time period is 1-4 seconds, the second time period is 2-5 seconds, and the third time period is 4-7 seconds. At this time, the second time period partially overlaps with the first time period, and the second time period partially overlaps with the third time period. It should be understood that the above 1-7 seconds is only used for example, and is not used to limit the first time period to 1-4 seconds, the second time period to 2-5 seconds, and the third time period to 4-7 seconds.

[0070] In some examples of this embodiment, when the scanning drive module 3 scans the Nth pixel row, the first data signal is output through the data line 2, including: when starting to scan the Nth pixel row, recording the scanning time for scanning the Nth pixel row; when the scanning time reaches the preset anti-error charging time, the data line 2 outputs the first data signal to charge the pixel capacitor of the Nth pixel row.

[0071] It should be understood that when scanning the pixel row, the thin film transistor of the pixel row is gradually turned on and off, rather than suddenly turned on or off. Therefore, if the data line 2 directly outputs the first data signal when scanning the Nth pixel row, and the data line 2 directly outputs the second data signal when scanning the Nth pixel row stops, the second data signal may be mistakenly charged into the pixel capacitor of the Nth pixel row, thereby affecting the display effect of the Nth pixel row. Therefore, in the driving method of the display panel provided in the present embodiment, when the scanning time reaches the preset anti-error charging time, the data line 2 outputs the first data signal to charge the pixel capacitor of the Nth pixel row. After the scanning starts and the preset anti-error charging time is reached, the data line 2 outputs the first data signal. Before the first data signal output by the data line 2 ends, the Nth pixel row has finished scanning and is no longer being charged. When the data line 2 outputs the second data signal, the Nth pixel row has finished scanning and is no longer being charged, thereby ensuring that the second data signal will not be charged into the pixel capacitor of the Nth pixel row, thereby achieving the effect of not affecting the display effect of the Nth pixel row, thereby improving the display effect of the display panel.

[0072] It should be understood that the scanning driving module 3 and the data driving module 4 in the pixel driving device provided in this embodiment can be combined to implement the various steps of the above-mentioned display panel driving method to achieve the same technical effects as the various steps of the above-mentioned display panel driving method, which will not be repeated here.
