[0026] The following is a detailed description with reference to specific embodiments. It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0027] See also Figure 1 , Figure 1 is a schematic diagram of the structure of the display panel provided in the embodiment of the present application. Figure 1 As shown, the display panel 10 includes a plurality of pixel unit rows 100 and a plurality of scan line groups 200 corresponding to the plurality of pixel unit rows 100. The plurality of pixel unit rows 100 may be divided into a plurality of pixel unit row sets R, and each pixel unit row 100 in each pixel unit row set R may be respectively divided into a plurality of pixel unit groups S (e.g., a first pixel unit group S1, a second pixel unit group S2, a third pixel unit group S3, and a fourth pixel unit group S4, etc.). Each scan line group 200 may include a plurality of scan lines L1, and for each scan line group 200, the plurality of scan lines L1 included therein may be connected to a plurality of pixel unit groups S in the corresponding pixel unit row 100 in a one-to-one correspondence. The scan line groups 200 corresponding to all pixel unit rows 100 in each pixel unit row set R may together constitute a corresponding scan line group set G, thereby obtaining a plurality of scan line group sets G corresponding to the plurality of pixel unit row sets R in a one-to-one correspondence.

[0028] Specifically, each scanning line group set G can be configured to provide scanning signals to the corresponding pixel unit row sets R in sequence during the process of displaying a frame of image on the display panel 10, so as to realize sequential scanning of the pixel units 101 in the above-mentioned multiple pixel unit row sets R, so that the pixel units 101 in the above-mentioned multiple pixel unit row sets R can be turned on in sequence.

[0029] Furthermore, each scan line group 200 in each scan line group set G may be configured to simultaneously provide scan signals to a plurality of pixel unit groups S of respective corresponding pixel unit rows 100 in the corresponding pixel unit row set R one by one during the process of the display panel 10 displaying a frame of image.

[0030] Specifically, Figure 1 As shown, each pixel unit row 100 may extend along the first direction X, and the plurality of pixel unit rows 100 included in the display panel 10 may be arranged along the second direction Y, and the plurality of pixel unit rows 100 may be sequentially divided into a plurality of pixel unit row sets R along the second direction Y, and each pixel unit row 100 may be sequentially divided into a plurality of pixel unit groups S (e.g., a first pixel unit group S1, a second pixel unit group S2, a third pixel unit group S3, and a fourth pixel unit group S4, etc.) along the first direction X. Each pixel unit row set R may include at least two pixel unit rows 200 that are sequentially adjacent in the second direction Y, for example, may specifically include an odd pixel unit row and an even pixel unit row that are adjacent in the second direction Y, and Figure 1 The pixel units 101 using the same filling method belong to the same pixel unit group S.

[0031] Specifically, Figure 1 Taking the example that each pixel unit row 100 shown is divided into a first pixel unit group S1, a second pixel unit group S2, a third pixel unit group S3 and a fourth pixel unit group S4, each scan line group 200 in each scan line group set G can be specifically configured as follows: when the display panel 10 displays a frame of image, a scan signal is first provided to the first pixel unit group S1 of the pixel unit row 100 corresponding to each other in the corresponding pixel unit row set R at the same time, and then a scan signal is provided to the second pixel unit group S2 of the pixel unit row 100 corresponding to each other in the corresponding pixel unit row set R at the same time, and then a scan signal is provided to the third pixel unit group S3 of the pixel unit row 100 corresponding to each other in the corresponding pixel unit row set R at the same time, and then a scan signal is provided to the fourth pixel unit group S4 of the pixel unit row 100 corresponding to each other in the corresponding pixel unit row set R at the same time.

[0032] In this way, not only can all pixel unit rows 100 in the same pixel unit row set R be scanned simultaneously, but also during the scanning process of each pixel unit row 100, scanning signals can be provided to multiple pixel unit groups S in each pixel unit row 100 in turn, so that the pixel units 101 in the multiple pixel unit groups S are turned on in turn, thereby simultaneously scanning multiple rows of pixels and avoiding turning on all pixels in the same row at the same time. Moreover, the more pixel rows scanned simultaneously, the more conducive it is to reducing the clock frequency required for the display panel to drive the pixels, thereby reducing the power consumption of the display panel, extending its service life, and improving its reliability and stability.

[0033] In addition, the inventor of the present application has found in long-term research and development that, in the process of simultaneously scanning multiple rows of pixels, if all the pixels of the multiple rows scanned simultaneously are turned on simultaneously, the switch tubes of all the pixels of the multiple rows scanned simultaneously will be turned on simultaneously, resulting in a problem of high noise on the display panel. Moreover, in the embodiment of the present application, in the process of simultaneously scanning all the pixel unit rows 100 of the same pixel unit row set R, for each pixel unit row 100, during the scanning process of the pixel unit row 100, a scanning signal is sequentially provided to each pixel unit group S in the pixel unit row 100, thereby realizing multiple scanning of the pixel unit row 100, and each scanning only scans one of the pixel unit groups S in the pixel unit row 100, thereby avoiding all the pixels in the same row from being turned on simultaneously, and reducing the noise of the display panel to improve the reliability of the display panel.

[0034] Specifically, the duration of displaying a frame of image on the display panel 10 is set to be a frame display period, and the frame display period may include a plurality of sub-display periods in sequence, and the plurality of sub-display periods may correspond one to one with the plurality of scan line group sets G. Accordingly, each scan line group set G may be specifically configured to provide a scan signal to each corresponding pixel unit row set in sequence in each corresponding sub-display period. Each scan line group 200 in each scan line group set G may be specifically configured to provide a scan signal to each of the plurality of pixel unit groups S of the corresponding pixel unit row 100 in the corresponding pixel unit row set R in the corresponding sub-display period of each scan line group set G.

[0035] For example, Figure 2 As shown, the multiple pixel unit rows 100 included in the above-mentioned display panel 10 can be divided into n pixel unit row sets, recorded as the first pixel unit row set R1, the second pixel unit row set R2, ..., the nth pixel unit row set Rn. Among them, the i-th pixel unit row set Ri can include m pixel unit rows 100, recorded as the first pixel unit row Ri1, the second pixel unit row Ri2, ..., the m-th pixel unit row Rim, i is a positive integer less than or equal to n, and m is an integer greater than 1. Among them, the j-th pixel unit row Rij in the i-th pixel unit row set Ri can be divided into p pixel unit groups, recorded as the first pixel unit group Rij1, the second pixel unit group Rij2, ..., the p-th pixel unit group Rijp, j is a positive integer less than or equal to m, p is an integer greater than 1, and Figure 2 The pixel units 101 using the same filling method belong to the same pixel unit group.

[0036] Correspondingly, the display panel 10 may include n scan line group sets G, which are recorded as the first scan line group set G1, the second scan line group set G2, ..., and the nth scan line group set Gn. The i-th scan line group set Gi may correspond to the i-th pixel unit row set Ri, and include m scan line groups 200, which are recorded as the first scan line group Gi1, the second scan line group Gi2, ..., and the m-th scan line group Gim. The j-th scan line group Gij in the i-th scan line group set Gi may correspond to the j-th pixel unit row Rij in the i-th pixel unit row set Ri, and include p scan lines L1, which are recorded as the first scan line L1ij1, the second scan line L1ij2, ..., and the p-th scan line L1ijp.

[0037] Correspondingly, a frame display period of the display panel 10 may include n sub-display periods in sequence, which are recorded as the first sub-display period T1, the second sub-display period T2, ..., and the nth sub-display period Tn. The i-th sub-display period Ti may correspond to the i-th scan line group set Gi, and may include q pixel group display periods in sequence, which are recorded as the first pixel group display period Ti1, the second pixel group display period Ti2, ..., and the q-th pixel group display period Tiq, where q is greater than or equal to p, and q is equal to the number of pixel unit groups S in the pixel unit row 100 having the largest number of pixel unit groups S among the plurality of pixel unit rows 100.

[0038] Correspondingly, the first scan line group set G1 can be specifically configured to provide a scan signal to the first pixel unit row set R1 within the first sub-display period T1; the second scan line group set G2 can be specifically configured to provide a scan signal to the second pixel unit row set R2 within the second sub-display period T2; ...; the nth scan line group set Gn can be specifically configured to provide a scan signal to the nth pixel unit row set Rn within the nth sub-display period Tn.

[0039] Furthermore, the first scan line L1ij1 included in the jth scan line group Gij in the i-th scan line group set Gi can be specifically configured as: in the first pixel group display period Ti1 in the i-th sub-display period Ti, a scan signal is provided to the first pixel unit group Rij1 of the j-th pixel unit row Rij in the i-th pixel unit row set Ri; the second scan line L1ij2 included in the j-th scan line group Gij in the i-th scan line group set Gi can be specifically configured as: in the second pixel group display period Ti2 in the i-th sub-display period Ti, a scan signal is provided to the second pixel unit group Rij2 of the j-th pixel unit row Rij in the i-th pixel unit row set Ri, ... , the p-th scan line L1ijp included in the j-th scan line group Gij in the i-th scan line group set Gi can be specifically configured as: in the p-th pixel group display period Tip in the i-th sub-display period Ti, a scan signal is provided to the p-th pixel unit group Rijp of the j-th pixel unit row Rij in the i-th pixel unit row set Ri. In this way, not only the m pixel unit groups S of different pixel unit rows 100 are scanned simultaneously in each pixel group display period, but also the p pixel unit groups S in the same pixel unit row 100 are scanned correspondingly in sequence in p pixel group display periods.

[0040] In some embodiments, Figure 3 As shown, the display panel 10 may further include a scan driving circuit 500, and the scan driving circuit 500 is connected to all scan lines L1 in each scan line group 200. In addition, the scan driving circuit 500 may be configured to provide scan signals to each scan line group set G in sequence during the process of displaying a frame of image on the display panel 10, and to provide scan signals to multiple scan lines L1 included in each scan line group 200 in the same scan line group set G one by one at the same time, so as to provide scan signals to the corresponding pixel unit row sets R in sequence through each scan line group set G, and to provide scan signals to the corresponding pixel unit row 100 in the corresponding pixel unit row set R through each scan line group 200 in each scan line group set G one by one at the same time.

[0041] Continuing with the previous example, the above-mentioned scan driving circuit 500 can be specifically configured as follows: in the first sub-display period T1, a scan signal is provided to the first pixel unit row set R1 through the first scan line group set G1; in the second sub-display period T2, a scan signal is provided to the second pixel unit row set R2 through the second scan line group set G2; ...; in the nth sub-display period Tn, a scan signal is provided to the nth pixel unit row set Rn through the nth scan line group set Gn.

[0042] Furthermore, when the scan driving circuit 500 provides a scan signal to the i-th pixel unit row set Ri through the i-th scan line group set Gi during the i-th sub-display period Ti, the scan driving circuit 500 may specifically perform the following steps: providing a scan signal to the first scan line L1ij1 included in the j-th scan line group Gij in the i-th scan line group set Gi during the first pixel group display period Ti1 in the i-th sub-display period Ti; providing a scan signal to the second pixel unit group Rij2 of the j-th pixel unit row Rij in the i-th pixel unit row set Ri during the second pixel group display period Ti2 in the i-th sub-display period Ti; ...; providing a scan signal to the p-th scan line L1ijp included in the j-th scan line group Gij in the i-th scan line group set Gi during the p-th pixel group display period Tip in the i-th sub-display period Ti.

[0043] In this embodiment, in the same pixel unit row set R, different pixel unit rows 100 may have the same or different numbers of pixel unit groups S. In other words, different pixel unit rows 100 in the same pixel unit row set R may be divided into the same or different numbers of pixel unit groups S. Specifically, Figure 1 Taking the display panel 10 shown as an example, each pixel unit row 100 in the same pixel unit row set R can be divided into four pixel unit groups S respectively.

[0044] In some embodiments, in the same pixel unit row set R, the number of pixel unit rows 100 may be greater than or equal to the number of pixel unit groups S in each pixel unit row 100 .

[0045] Specifically, for each pixel cell row set R, when the number of pixel cell groups S possessed by different pixel cell rows 100 in the pixel cell row set R is the same, the number of pixel cell rows 100 possessed by the pixel cell row set R may be greater than or equal to the number of pixel cell groups S possessed by any pixel cell row 100 in the pixel cell row set R.

[0046] Specifically, for each pixel cell row set R, when different pixel cell rows 100 in the pixel cell row set R have different numbers of pixel cell groups S, the number of pixel cell rows 100 in the pixel cell row set R may be greater than or equal to the number of pixel cell groups S in the pixel cell row set R having the largest number of pixel cell groups S.

[0047] Exemplarily, taking the above-mentioned i-th pixel unit row set Ri as an example, the i-th pixel unit row set Ri includes m pixel unit rows 100, and m may be greater than or equal to N1, and N1 is equal to the number of pixel unit groups S of the pixel unit row 100 having the largest number of pixel unit groups S among the m pixel unit rows 100. Moreover, within one clock cycle (i.e., pixel group display cycle), at most m pixel unit groups S can be scanned simultaneously, and the m pixel unit groups S correspond one-to-one to the m pixel unit rows 100 in the same pixel unit row set R (i.e., the i-th pixel unit row set Ri), so that the scanning of all pixel units 101 of the m pixel unit rows 100 in the i-th pixel unit row set Ri can be completed within N1 clock cycles.

[0048] In this way, by setting m greater than N1, that is, N1 less than m, compared with the scheme in the related art in which the pixel array is scanned row by row and the time length for scanning m rows of pixels is m clock cycles, the embodiment of the present application achieves the reduction of the time length for scanning m rows of pixels from m clock cycles to N1 clock cycles, thereby being able to reduce the clock frequency required for the display panel 10 to drive the pixels, thereby reducing the power consumption of the display panel, extending its service life, and improving its reliability and stability.

[0049] In some embodiments, Figure 1 As shown, each pixel unit row 100 may extend along a first direction X, and the plurality of pixel unit rows 100 included in the display panel 10 may be arranged along a second direction Y to form a pixel unit array, the second direction Y intersecting with the first direction X, and illustratively, the second direction Y may be perpendicular to the first direction X. Specifically, the pixel unit array may include a plurality of pixel unit columns 300, and the display panel 10 may further include a plurality of data line groups 400 connected to the plurality of pixel unit columns 300 in a one-to-one correspondence.

[0050] Furthermore, each data line group 400 can be configured as follows: in the process of the display panel 10 displaying a frame of image, data signals are provided in sequence to the pixel cells 101 belonging to each pixel cell row set R in the corresponding pixel cell column 300, and data signals are provided to the pixel cells 101 of each pixel cell row 100 belonging to the same pixel cell row set R in the corresponding pixel cell column 300 at the same time. Thus, not only can the pixel cell row sets R corresponding to each scanning line group set G be ensured to receive data signals in sequence when each scanning line group set G provides scanning signals to each corresponding pixel cell row set R in sequence, but also the pixel cell groups S of different pixel cell rows 100 in the same pixel cell row set R can be ensured to receive data signals at the same time when the pixel cell groups S of different pixel cell rows 100 in the same pixel cell row set R are scanned simultaneously.

[0051] Specifically, Figure 1 As shown, each data line group 400 can be respectively connected to all pixel units 101 belonging to each pixel unit row set R in the corresponding pixel unit column 300, and for each data line group 400, the pixel units 101 of different pixel unit rows 100 belonging to the same pixel unit row set R in the pixel unit column 300 corresponding to the data line group 400 can be correspondingly connected to different data lines L2 in the data line group 400.

[0052] Specifically, Figure 1 As shown, the data line L2 can extend along the second direction Y, the above-mentioned multiple data line groups 400 can be arranged along the first direction X, and each data line group 400 can be arranged on one side or two opposite sides of its corresponding pixel unit column 300 along the first direction X to reduce the signal attenuation problem during the transmission of the data signal on the data line L2.

[0053] Specifically, Figure 1 As shown, the scan line L1 can extend along the first direction X, the above-mentioned multiple scan line groups 200 can be arranged along the second direction Y, and each scan line group 200 can be arranged on one side or two opposite sides of its corresponding pixel unit row 100 along the second direction Y to reduce the signal attenuation problem during the transmission of the scan signal on the scan line L1.

[0054] In some specific embodiments, Figure 1 As shown, the multiple pixel unit groups S (for example, the first pixel unit group S, the second pixel unit group S2, the third pixel unit group S3 and the fourth pixel unit group S4) of each pixel unit row 100 can be arranged along the first direction X. In addition, the display panel 10 can have multiple display areas A (for example, the first display area A1, the second display area A2, the third display area A3 and the fourth display area A4) arranged along the first direction X, and the multiple pixel unit groups S of each pixel unit row 100 can be arranged in the multiple display areas A in a one-to-one correspondence, so that the pixel units 101 of the same pixel unit group S in the same pixel unit row 100 are located in the same area, and the pixel units 101 of different pixel unit groups S in the same pixel unit row 100 are located in different areas.

[0055] Specifically, Figure 1As shown, the number of pixel unit rows 100 in each pixel unit row set R can be equal, and can be greater than or equal to 2, for example, can be equal to 2, 3, 4, 5, 6, 7, 8, 9 or 10, but not limited to the listed values, and other values ​​not listed in the numerical range are also applicable.
