Summary of the Invention

[0006] In a second aspect, an embodiment of the present application further provides a display device, including the display panel as described in the embodiment of the first aspect.
[0007] According to an embodiment of the present application, a single data frame includes a plurality of display phases and a plurality of touch phases arranged alternately. The plurality of display phases within a single data frame correspond to all pixel rows of the display panel, and each display phase corresponds to a partial pixel row of the display panel. The driving module provides a display driving signal during the display phase in accordance with the arrangement order of the plurality of display phases and the plurality of touch phases, enabling the display panel to implement a display function according to the display driving signal provided by the driving module during the display phase.

It should be noted that the embodiments provided in the embodiments of the present application can be combined with each other without conflict.
[0024] With the development and progress of technology, display driver chips and touch chips have been greatly developed, and some current high-end chips integrate display and touch functions. In the lit screen mode, in order to simultaneously implement display and touch functions, display driving signals and touch driving signals are alternately provided until the display and touch scans within one frame time are completed.
[0025] In a data frame of the display panel, when the display driving signal and the touch driving signal alternate, the display stage and the touch stage of the display panel alternate. At this time, the display panel is in the holding state of the current display stage and enters the touch stage. When switching from the touch stage to the next display stage, due to the different voltages between the pixel rows corresponding to the junction of the two display stages, a difficult-to-block horizontal stripe display phenomenon will occur. Moreover, during the multi-frame display process of the display panel, the horizontal stripe display phenomenon of each frame will be superimposed, resulting in a more obvious highlighted display line, thereby affecting the display effect of the display panel and the user experience. Therefore, how to reduce the horizontal stripe display phenomenon existing on the display panel has become a technical problem that those skilled in the art urgently need to solve.
[0026] To solve the above technical problems, the embodiments of the present application provide a display panel and a display device. The following will describe the embodiments of the present application with reference to the accompanying drawings.
[0027] The embodiments of the present application provide a display panel, and the display panel includes a driving module.
[0028] A single data frame includes a plurality of alternately arranged display stages and a plurality of touch stages, and the driving module is configured to provide a display driving signal in the display stage and a touch driving signal in the touch stage.
[0029] Specifically, multiple display phases within a single data frame correspond to all pixel rows of the display panel, and each display phase corresponds to a partial pixel row of the display panel. Multiple touch phases within a single data frame correspond to all touch electrodes of the display panel, and each touch phase corresponds to a partial touch electrode of the display panel. In a single data frame, the driving module drives the partial pixel rows corresponding to each display phase to emit light by outputting a display driving signal, and drives the partial touch electrodes corresponding to each touch phase to enable the touch function by outputting a touch driving signal. The driving module alternately outputs the display driving signal and the touch driving signal until all pixel rows of the display panel receive the display driving signal or the corresponding level transmission signal, and all touch electrodes receive the touch driving signal or the corresponding level transmission signal, thereby implementing the display and touch functions of the display panel within a single data frame.
[0030] Among two adjacent data frames, the number of pixel rows corresponding to at least one display phase in one data frame is different from the number of pixel rows corresponding to at least one display phase in the other data frame.
[0031] Exemplarily, Figure 1 The schematic diagram showing the display situation of the display panel provided by an embodiment of the present application in two adjacent data frames is as follows. Figure 1 As shown, the first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows. The first data frame 100 includes 10 display phases 110. Therefore, each display phase 110 corresponds to 25 pixel rows. The display phases 110 and the touch phases are alternately arranged. Therefore, the first data frame 100 further includes 9 touch phases. In the first data frame 100, there is a highlighted display line 300 generated due to the horizontal stripe display phenomenon for every 25 pixel rows on the display panel 10, and there are a total of 9 highlighted display lines 300.
[0032] It should be noted that the fact that the display panel 10 has 250 pixel rows, the number of display phases 110 in the first data frame 100, and the number of pixel rows of each display phase 110 are the same are all examples. The number of pixel rows of the display panel 10 and the number of display phases 110 need to be set according to the actual situation, and the number of pixel rows of each display phase 110 can also be different, which is not specifically limited herein.
[0033] As an example, continue to refer to Figure 1, the second data frame 200 also includes 10 display phases 110. However, the first 9 display phases 110 correspond to 26 pixel rows, and the last display phase 110 corresponds to 16 pixel rows. The display phases 110 and the touch phases are alternately arranged. Therefore, the second data frame 200 further includes 9 touch phases. In the second data frame 200, there is a highlighted display line 300 caused by the horizontal stripe display phenomenon for every 26 pixel rows on the display panel 10. There are also 9 such highlighted display lines 300 in total. The positions of these 9 highlighted display lines 300 are each 1 pixel row different from the positions of the corresponding highlighted display lines 300 in the first data frame 100.
[0034] As another example, Figure 2 shows a schematic diagram of the display situation of the display panel 10 provided by another embodiment of the present application in two adjacent data frames, as Figure 2 shown. The first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows. The first data frame 100 includes 10 display phases 110. The second data frame 200 also includes 10 display phases 110. However, the number of pixel rows corresponding to the 10 display phases 110 are 24, 23, 22, 21, 20, 19, 18, 17, 16, and 70 in sequence. The display phases 110 and the touch phases are alternately arranged. Therefore, the second data frame 200 further includes 9 touch phases. In the second data frame 200, there is a highlighted display line 300 caused by the horizontal stripe display phenomenon at the positions of the pixel rows where the display phases 110 and the touch phases alternate on the display panel 10. There are 9 such highlighted display lines 300 in total. However, the positions of the 9 highlighted display lines 300 in the second data frame 200 are each different from the positions of the corresponding highlighted display lines 300 in the first data frame 100 by multiple pixel rows.
[0035] As another example, Figure 3 shows a schematic diagram of the display situation of the display panel 10 provided by another embodiment of the present application in two adjacent data frames, as Figure 3As shown, the first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows, and the first data frame 100 includes 10 display phases 110. The first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows, and the first data frame 100 includes 10 display phases 110. Therefore, each display phase 110 corresponds to 25 pixel rows. The display phases 110 and the touch phases are alternately arranged. Therefore, the first data frame 100 further includes 9 touch phases. In the first data frame 100, there is one highlighted display line 300 caused by the horizontal stripe display phenomenon for every 25 pixel rows on the display panel 10, and there are a total of 9 highlighted display lines 300. The second data frame 200 includes 8 display phases 110. The first 7 display phases 110 correspond to 31 pixel rows, and the 8th display phase 110 corresponds to 33 pixel rows. The display phases 110 and the touch phases are alternately arranged. Therefore, the second data frame 200 further includes 7 touch phases. In the second data frame 200, there is one highlighted display line 300 caused by the horizontal stripe display phenomenon for every 31 pixel rows on the display panel 10, and there are a total of 7 highlighted display lines 300. The positions of the 7 highlighted display lines 300 in the second data frame 200 are different from the positions of the corresponding highlighted display lines 300 in the first data frame 100.
[0036] Therefore, in two adjacent data frames, the positions where the display phases 110 and the touch phases alternate are different, so that the positions where the horizontal stripe display phenomenon occurs in two adjacent data frames are different. Furthermore, during the display process of the display panel 10, the positions where the horizontal stripe display phenomenon occurs are dispersed. Therefore, the brightness of the highlighted display lines caused by the horizontal stripe display phenomenon can be weakened, thereby reducing the horizontal stripe display phenomenon existing on the display panel 10.
[0037] It should be noted that the number of display phases 110 in the second data frame 200 and the number of pixel rows by which one display phase 110 in the second data frame 200 differs from one display phase 110 in the first data frame 100 need to be set according to the actual situation. The number of pixel rows in each display phase 110 of the second data frame 200 can be such that the number of pixel rows in multiple display phases 110 is the same, the number of pixel rows in other display phases 110 is different, or the number of pixel rows in all display phases 110 is set to be different. Specific limitations are not made here.
[0038] In some embodiments, in the i-th data frame, the driving module is configured to sequentially provide display driving signals to N pixel rows in one display phase.
[0039] In the (i + 1)-th data frame, the driving module is used to provide display driving signals row by row to M pixel rows in one display stage.
[0040] Wherein, i, N, and M are positive integers, and N ≠ M.
[0041] Exemplarily, taking i as 1, N as 25, M as 20, and the display panel including 100 pixel rows as an example. Figure 4 The schematic diagram showing the display situation of the display panel provided by another embodiment of the present application in two adjacent data frames is as Figure 4 shown. In the 1st data frame, the display panel 10 includes 4 display stages 110, and the driving module is used to provide display driving signals row by row to 25 pixel rows in one display stage 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of the 25th pixel row, 50th pixel row, and 75th pixel row of the display panel 10. In the 2nd data frame, the display panel 10 includes 5 display stages 110, and the driving module is used to provide display driving signals row by row to 20 pixel rows in one display stage 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of the 20th pixel row, 40th pixel row, 60th pixel row, and 80th pixel row of the display panel 10. Based on this, the difference between the 25 pixel rows corresponding to the 1st data frame and the 20 pixel rows corresponding to the 2nd data frame is 5. Therefore, M = N - a, where a = 5. And since M is a positive integer not equal to 0, a is a positive integer not greater than N.
[0042] It can be seen that there are 3 highlighted display lines in the 1st data frame and 4 highlighted display lines in the 2nd data frame. Therefore, the positions where the highlighted display lines are generated in the 1st data frame and the 2nd data frame are not the same. Furthermore, it is possible to avoid the highlighted display lines that are generated multiple times at the same position in multiple data frames of the display panel 10, so that the positions where the horizontal stripe display phenomenon occurs in the display panel 10 are dispersed, thereby weakening the brightness of each highlighted display line and achieving the reduction of the horizontal stripe display phenomenon existing on the display panel 10.
[0043] It should be noted that taking i as 1, N as 25, M as 20, and the display panel including 100 pixel rows is only an example and is not specifically limited herein.
[0044] In some embodiments, in the (i + 2)-th data frame, the driving module is used to provide display driving signals row by row to L pixel rows in one display stage.
[0045] Wherein, M = N - a; L = M - a; a is a positive integer not greater than N.
[0046] As an example, taking i as 1, N as 25, M as 20, L as 15, and the display panel including 300 pixel rows, based on this, the difference between the 25 pixel rows corresponding to the first data frame and the 20 pixel rows corresponding to the second data frame is 5. Therefore, M = N - a. The difference between the 20 pixel rows corresponding to the second data frame and the 15 pixel rows corresponding to the third data frame is 5. Therefore, L = M - a, where a = 5. And M is a positive integer not equal to 0, so a is a positive integer not greater than N.
[0047] Figure 5 The schematic diagram showing the display situation of the display panel provided by another embodiment of the present application in two adjacent data frames is as Figure 5 shown. In the first data frame, the display panel 10 includes 12 display stages 110. The driving module is used to provide display driving signals to 25 pixel rows row by row in one display stage 110. Therefore, there are 11 highlighted display lines due to the horizontal stripe display phenomenon at the corresponding positions on the display panel 10. In the second data frame, the display panel 10 includes 15 display stages 110. The driving module is used to provide display driving signals to 20 pixel rows row by row in one display stage 110. Therefore, there are 14 highlighted display lines due to the horizontal stripe display phenomenon at the corresponding positions on the display panel 10. In the third data frame, the display panel 10 includes 20 display stages 110. The driving module is used to provide display driving signals to 15 pixel rows row by row in one display stage 110. Therefore, there are 19 highlighted display lines due to the horizontal stripe display phenomenon at the corresponding positions on the display panel 10. And in the first data frame, the second data frame, and the third data frame, there is a situation where the highlighted display lines of two data frames overlap. However, compared with the situation where the highlighted display lines of all data frames overlap, the present application realizes the dispersion of the positions where the horizontal stripe display phenomenon occurs. Therefore, the brightness of the highlighted display lines caused by the horizontal stripe display phenomenon can be weakened, thereby realizing the weakening of the horizontal stripe display phenomenon existing on the display panel 10.
[0048] It should be noted that taking i as 1, N as 25, M as 20, L as 15, and the display panel including 300 pixel rows is only an example and is not specifically limited here.
[0049] As another example, taking i as 1, N as 11, M as 9, L as 7, and the display panel including 693 pixel rows as an example, so a is 2. In the first data frame, the driving module provides display driving signals to 11 pixel rows row by row in one display stage, so there are 63 display stages and 62 touch stages, and there are highlighted display lines caused by the horizontal stripe display phenomenon at the positions where the display stage and the touch stage alternate, that is, there are 62 highlighted display lines in the first data frame. In the second data frame, the driving module provides display driving signals to 9 pixel rows row by row in one display stage, so there are 77 display stages, 76 touch stages and 76 highlighted display lines. In the third data frame, the driving module provides display driving signals to 7 pixel rows row by row in one display stage, so there are 99 display stages, 98 touch stages and 98 highlighted display lines. It can be seen that there are 62 highlighted display lines in the first data frame, 76 highlighted display lines in the second data frame, 96 highlighted display lines in the third data frame, and the positions where the highlighted display lines are generated in the first data frame, the second data frame and the third data frame are all different, so the horizontal stripe display phenomenon existing on the display panel can be weakened to the greatest extent.
[0050] It should be noted that taking i as 1, N as 11, M as 9, L as 7, and the display panel including 693 pixel rows is only an example and is not specifically limited here.
[0051] In some embodiments, in the (i + k)-th data frame, the driving module is configured to provide display driving signals to N pixel rows row by row in one display stage.
[0052] In the i-th data frame to the (i + k - 1)-th data frame, the number of pixel rows corresponding to one display stage of each data frame is different from each other.
[0053] Exemplarily, take i as 1 and k as 2 for example. In the first data frame, the driving module is used to provide display driving signals row by row to N pixel rows in a display stage. In the (i + k - 1)-th data frame, that is, the second data frame, the driving module is used to provide display driving signals row by row to M pixel rows in a display stage. And in the (i + k)-th data frame, that is, the third data frame, the driving module is used to provide display driving signals row by row to N pixel rows in a display stage. It can be seen that the driving module provides display driving signals to the same number of pixel rows in the third data frame as in the first data frame, that is, after the display panel completes the display of the first data frame and the second data frame, the third data frame adopts the same display method as the first data frame. And in the first data frame and the second data frame, the number of pixel rows corresponding to a display stage in these two data frames is not the same, that is, in the i-th data frame to the (i + k - 1)-th data frame, the number of pixel rows corresponding to a display stage in each data frame is different from each other. Therefore, the positions where the horizontal stripe display phenomenon occurs during the display of the display panel are dispersed, and the brightness of the highlighted display lines generated due to the horizontal stripe display phenomenon is weakened, thereby reducing the horizontal stripe display phenomenon existing on the display panel.
[0054] In some embodiments, in any two data frames, the number of touch stages remains the same.
[0055] Exemplarily, Figure 6 The figure shows a schematic diagram of the display situation of the display panel provided by another embodiment of the present application in two adjacent data frames, as Figure 6 shown. Take i as 1, N as 25, M as 20, and the display panel 10 includes 100 pixel rows, and the number of touch stages is 3 for example. In the first data frame, since the number of touch stages is 3, the number of display stages 110 is 4, and the number of pixel rows corresponding to each display stage 110 is 25. Therefore, there are three highlighted display lines generated due to the horizontal stripe display phenomenon at the positions of 25 pixel rows, 50 pixel rows, and 75 pixel rows of the display panel 10.
[0056] In the second data frame, since the number of touch stages is 3, the number of display stages 110 is 4. Therefore, in the first three display stages 110, the driving module provides display driving signals to 20 pixel rows, but there are still 40 pixel rows not displayed. Therefore, in the fourth display stage 110, the driving module provides display driving signals to 40 pixel rows. Therefore, there are three highlighted display lines generated due to the horizontal stripe display phenomenon at the positions of 20 pixel rows, 40 pixel rows, and 60 pixel rows of the display panel 10.
[0057] It can be seen that in the first data frame and the second data frame, since the number of touch stages is the same, the number of highlighted lines is also the same. In the first data frame and the second data frame, although there are three highlighted lines, the positions of each highlighted line are different. Therefore, it is possible to disperse the positions of the highlighted lines that appear during the display of the display panel 10, thereby weakening the brightness of the highlighted lines and weakening the horizontal stripe display phenomenon existing on the display panel 10.
[0058] In some embodiments, in two adjacent data frames, the time for providing a display driving signal in at least one display stage of one data frame is different from the time for providing a display driving signal in at least one display stage of the other data frame.
[0059] Specifically, the driving module changes the time for providing a display driving signal within one display stage, thereby changing the number of pixel rows receiving the display driving signal within one display stage. When the time for providing a display driving signal in one display stage is the same as the time for providing a display driving signal in another display cut-off, the number of pixel rows receiving the display driving signal in these two display stages is the same. When the time for providing a display driving signal in one display stage is different from the time for providing a display driving signal in another display cut-off, the number of pixel rows receiving the display driving signal in these two display stages is different.
[0060] Therefore, in two adjacent data frames, the time for providing a display driving signal in at least one display stage of one data frame is different from the time for providing a display driving signal in at least one display stage of the other data frame, which means that the number of pixel rows corresponding to one display stage in one data frame is different from the number of pixel rows corresponding to one display stage in the other data frame, and thus at least one highlighted line in these two data frames has a different position. Further, by changing the time for the driving module to provide a display driving signal in each display stage, the number of pixel rows corresponding to each display stage can be changed, so as to disperse the positions of the highlighted lines that appear during the display stage of the display panel, thereby weakening the brightness of the highlighted lines and weakening the horizontal stripe display phenomenon existing on the display panel.
[0061] In some embodiments, in two adjacent data frames, the total time for the driving module to provide a display driving signal in all display stages is the same.
[0062] Specifically, since the total number of pixel rows in the display panel is fixed, and the driving module outputs display driving signals to each pixel row for the same amount of time, changing only the number of display phases or the number of pixel rows in a single display phase in two adjacent data frames will not change the total number of pixel rows in the display panel. Therefore, in two adjacent data frames, the total time for the driving module to provide display driving signals in all display phases is the same. By setting the total time for providing display driving signals in all display phases to be the same in two adjacent data frames, the present application can adjust the number of display phases by simply adjusting the time for providing display driving signals in a single display phase. Compared with the case where the total time for the driving module to provide display driving signals in all display phases in two adjacent data frames is different, the number of corresponding pixel rows in each display phase in the present application is easier to control.
[0063] In some embodiments, the number of touch phases is different in two adjacent data frames.
[0064] Exemplarily, continue to refer to Figure 4 , in the first data frame, the display panel 10 includes 3 touch phases, and in the second data frame, the display panel 10 includes 4 touch phases. The number of touch phases in the first data frame and the second data frame is different. Since in one data frame, the display phase 110 and the touch phase are alternately arranged, in two adjacent data frames, the display panel 10 in the first data frame includes 4 display phases 110, and the display panel 10 in the second data frame includes 5 display phases 110. Correspondingly, in the first data frame, there are 3 highlighted display lines, and in the second data frame, there are 4 highlighted display lines, and the positions where the highlighted display lines are generated in the first data frame and the second data frame are not the same.
[0065] Continue to refer to Figure 5, in the first data frame, the display panel 10 includes 11 touch stages, and in the second data frame, the display panel 10 includes 14 touch stages. The number of touch stages in the first data frame and the second data frame is different. Therefore, in two adjacent data frames, in the first data frame, the display panel 10 includes 12 display stages 110, and in the second data frame, the display panel 10 includes 15 display stages 110. Correspondingly, in the first data frame, there are 11 highlighted display lines, while in the second data frame, there are 14 highlighted display lines, and the positions where the highlighted display lines are generated in the first data frame and the second data frame are not the same. In the third data frame, the display panel 10 includes 20 display stages 110. Therefore, in the third data frame, there are 19 touch stages, and the number of touch stages in the second data frame and the third data frame is different. Also, in the third data frame, there are 19 highlighted display lines, and the positions where the highlighted display lines are generated in the second data frame and the third data frame are not the same.
[0066] It can be seen that in two adjacent data frames, by setting different numbers of touch stages in the present application, correspondingly, the numbers of display stages 110 are different, and further, the numbers of highlighted display lines are different. Moreover, the positions where the highlighted display lines are generated in two adjacent data frames are not the same, so that the highlighted display lines generated at the same position in the display panel 10 in two adjacent data frames can be avoided, and the positions where the display panel 10 has the horizontal stripe display phenomenon during the display process are dispersed, thereby weakening the brightness of each highlighted display line and achieving the reduction of the horizontal stripe display phenomenon existing on the display panel 10.
[0067] In some embodiments, the number of pixel rows of the display panel is P;
[0068] In the i-th data frame, there are b touch stages, and the number of pixel rows corresponding to one display stage is:
[0069] P / (b + 1);
[0070] In the (i + 1)-th data frame, there are c touch stages, and the number of pixel rows corresponding to one display stage is:
[0071] P / (c + 1); where
[0072] b and c are positive integers not greater than P, and b is different from c.
[0073] Exemplarily, the number of pixel rows of the display panel is 100. Continue to refer to Figure 4, the first data frame includes 3 touch stages. Since the display stage 110 and the touch stages are alternately arranged, the first data frame includes 4 display stages 110. The number of pixel rows corresponding to one display stage 110 is P / (b + 1) = 100 / (3 + 1) = 25. In the first data frame, the driving module is used to provide display driving signals row by row to 25 pixel rows in one display stage 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of the 25th, 50th, 75th pixel rows on the display panel 10.
[0074] The second data frame includes 4 touch stages. Therefore, the second data frame includes 5 display stages 110. The number of pixel rows corresponding to one display stage 110 is P / (b + 1) = 100 / (4 + 1) = 20. In the second data frame, the driving module is used to provide display driving signals row by row to 20 pixel rows in one display stage 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of the 20th, 40th, 60th, and 80th pixel rows on the display panel 10.
[0075] It can be seen that there are 3 highlighted display lines in the first data frame and 4 highlighted display lines in the second data frame. Therefore, the positions where the highlighted display lines are generated in the first data frame and the second data frame are not the same. Furthermore, it is possible to avoid the highlighted display lines that are generated at the same position in multiple data frames on the display panel 10, so that the positions where the horizontal stripe display phenomenon occurs on the display panel 10 are dispersed, thereby weakening the brightness of each highlighted display line and achieving the reduction of the horizontal stripe display phenomenon existing on the display panel 10.
[0076] In some embodiments, in the (i + k)-th data frame, there are b touch stages;
[0077] In the i-th data frame to the (i + k - 1)-th data frame, the number of touch stages included in any two data frames is different.
[0078] Exemplarily, take i as 1 and k as 2. The first data frame includes b touch stages, and the third data frame also includes b touch stages. It can be seen that the number of touch stages in the first data frame of the display panel is the same as that in the third data frame. That is, after the display panel completes the display of the first data frame and the second data frame, the third data frame adopts the same display method as the first data frame. And in the first data frame and the second data frame, the number of touch stages included in these two data frames is different. Therefore, the positions where the display panel generates the highlighted display lines in these two data frames are different. Furthermore, the positions where the display panel shows the horizontal stripe display phenomenon during the display process are dispersed, and the brightness of the highlighted display lines caused by the horizontal stripe display phenomenon is weakened, thus reducing the horizontal stripe display phenomenon existing on the display panel.
[0079] In some embodiments, in two adjacent data frames, the driving module provides the touch driving signal for different lengths of time in one touch stage.
[0080] Specifically, the driving module changes the number of touch electrodes receiving the touch driving signal in one touch stage by changing the time for providing the touch driving signal in one touch stage. Since the total number of touch electrodes in the display panel is fixed, by changing the number of touch electrodes receiving the touch driving signal in one touch stage, the number of touch stages can be changed. Therefore, in two adjacent data frames, the driving module provides the touch driving signal for different lengths of time in one touch stage, which means that the number of touch stages in one data frame is different from that in the other data frame, and thus the number of display stages in these two data frames is different. Furthermore, the positions of each highlighted display line are different. Therefore, the positions where the display panel shows the highlighted display lines during the display stage are dispersed, and the brightness of the highlighted display lines is reduced, weakening the horizontal stripe display phenomenon existing on the display panel.
[0081] In some embodiments, in two adjacent data frames, the total time for the driving module to provide the touch driving signal in all touch stages is the same.
[0082] Specifically, since the total number of touch electrodes in the display panel is fixed, and the driving module provides touch driving signals to each touch electrode for the same amount of time, changing only the number of touch phases in two adjacent data frames does not change the total number of touch electrodes in the display panel. Therefore, in two adjacent data frames, the total time for the driving module to provide touch driving signals in all touch phases is the same. By setting the total time for the driving module to provide touch driving signals in all touch phases to be the same in two adjacent data frames, the present application can adjust the number of touch phases by simply adjusting the time for providing touch driving signals in a single touch phase. The present application makes it easier to adjust the number of touch electrodes corresponding to each touch phase.
[0083] In some embodiments, in the same data frame, the number of pixel rows corresponding to each display phase is the same.
[0084] Exemplarily, taking the display panel including 100 pixel rows as an example, continue to refer to Figure 4 , in the first data frame, the display panel 10 includes 4 display phases 110, and the driving module is used to provide display driving signals row by row to 25 pixel rows in one display phase 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of 25 pixel rows, 50 pixel rows, and 75 pixel rows on the display panel 10. In the second data frame, the display panel 10 includes 5 display phases 110, and the driving module is used to provide display driving signals row by row to 20 pixel rows in one display phase 110. Therefore, there are highlighted display lines due to the horizontal stripe display phenomenon at the positions of 20 pixel rows, 40 pixel rows, 60 pixel rows, and 80 pixel rows on the display panel 10. It can be seen that in the first data frame and the second data frame, the number of pixel rows corresponding to each display phase 110 is the same. In the first data frame, the number of pixel rows corresponding to each display phase 110 is 25, and in the second data frame, the number of pixel rows corresponding to each display phase 110 is 20. By setting the number of pixel rows corresponding to each display phase in the same data frame to be the same and the number of pixel rows corresponding to the display phases in different data frames to be different, the present application disperses the positions where the horizontal stripe display phenomenon occurs during the display process of the display panel. Therefore, the brightness of the highlighted display lines caused by the horizontal stripe display phenomenon can be weakened, thereby reducing the horizontal stripe display phenomenon existing on the display panel.
[0085] In some embodiments, in the same data frame, the number of pixel rows corresponding to at least one display phase is different from the number of pixel rows corresponding to other display phases.
[0086] Exemplarily, the number of pixel rows corresponding to at least one display stage is different from the number of pixel rows corresponding to other display stages. It can be that only the number of pixel rows corresponding to one display stage is different from the number of pixel rows corresponding to other display stages. Continuing to refer to Figure 1 , the first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows. The first data frame 100 includes 10 display stages 110. Therefore, each display stage 110 corresponds to 25 pixel rows. The second data frame 200 also includes 10 display stages 110. However, the first 9 display stages 110 correspond to 26 pixel rows, and the last display stage 110 corresponds to 16 pixel rows. Thus, although there is one display stage 110 in the second data frame 200 whose corresponding number of pixel rows is different from that of other display stages 110, the positions of the 9 highlighted display lines in the second data frame 200 are all different from the positions of the corresponding highlighted display lines in the first data frame 100.
[0087] The number of pixel rows corresponding to at least one display stage 110 is different from the number of pixel rows corresponding to other display stages 110. It can be that the number of pixel rows corresponding to all display stages 110 are different from each other. Continuing to refer to Figure 2 , the first data frame 100 and the second data frame 200 are two adjacent data frames. The display panel 10 has, for example, 250 pixel rows. The first data frame 100 includes 10 display stages 110. Therefore, each display stage 110 corresponds to 25 pixel rows. The second data frame 200 also includes 10 display stages 110. However, the number of pixel rows corresponding to the 10 display stages 110 are 24, 23, 22, 21, 20, 19, 18, 17, 16, and 70 in sequence. Thus, the number of pixel rows corresponding to all display stages 110 in the second data frame 200 are different from each other. Therefore, in two adjacent data frames, the number of pixel rows of the display stage 110 is different, so that the position where the display stage 110 alternates with the touch stage is different, and the position where the horizontal stripe display phenomenon occurs in two adjacent data frames is different. Furthermore, during the display process of the display panel 10, the positions where the horizontal stripe display phenomenon occurs are dispersed. Therefore, the brightness of the highlighted display lines caused by the horizontal stripe display phenomenon can be weakened, thereby reducing the horizontal stripe display phenomenon existing on the display panel 10.
[0088] It should be noted that the situation where the number of pixel rows corresponding to at least one display stage is different from the number of pixel rows corresponding to other display stages, being that only the number of pixel rows corresponding to one display stage is different from the number of pixel rows corresponding to other display stages, or being that the number of pixel rows corresponding to all display stages are different from each other, is only an example and is not specifically limited here.
[0089] In some embodiments, the driving module further includes: a driving sub-module and a touch control sub-module.
[0090] The driving sub-module is used to provide a display driving signal during the display stage.
[0091] The touch control sub-module is used to provide a touch control driving signal during the touch control stage.
[0092] Exemplarily, the driving module may be a driving chip or a Chip On Flex (COF). The driving sub-module and the touch control sub-module may be independent structures, or may be multiplexed in the same driving chip or COF structure.
[0093] In each data frame, there are multiple display stages and multiple touch control stages alternately arranged. During the display stage, the driving sub-module provides a display driving signal to the corresponding pixel row, and during the touch control stage, the touch control sub-module provides a touch control driving signal to the corresponding touch electrode. The driving sub-module first provides a display driving signal to the pixel row corresponding to the first display stage. After the first display stage ends, the touch control sub-module provides a touch control driving signal to the touch electrode corresponding to the first touch control stage. After the first touch control stage ends, the driving sub-module provides a display driving signal to the pixel row corresponding to the second display stage, and so on until the first data frame ends. The driving module completes the output of signals to all pixel rows and touch electrodes and enters the next data frame. In this application, by setting the time for the driving sub-module to provide a display driving signal during a display stage, or by setting the time for the touch control sub-module to provide a touch control driving signal during a touch control stage, the number of display stages or touch control stages can be changed, and thus, in different data frames, the positions of the horizontal stripe display phenomena generated due to the alternation of the display stage and the touch control stage are different, so that the positions of the horizontal stripe display phenomena are dispersed. Therefore, the brightness of the highlighted display lines generated due to the horizontal stripe display phenomena can be weakened, thereby reducing the horizontal stripe display phenomena existing on the display panel.
[0094] In some embodiments, Figure 7 The structural schematic diagram of a display panel provided by an embodiment of the present application is shown. As Figure 7 shown, the display panel further includes: a plurality of touch control signal lines 410 and touch electrodes 420 arranged in an array.
[0095] The touch control sub-module 430 is electrically connected to the plurality of touch control signal lines 410, and the touch control signal lines 410 are connected to a corresponding touch electrode 420.
[0096] Specifically, each of the multiple touch signal lines 410 is connected to a touch electrode 420 in a one-to-one correspondence. The touch sub-module 430 is configured to sequentially output touch drive signals to the multiple touch signal lines 410 during a touch stage, so that the touch signal lines 410 provide touch drive signals to the corresponding touch electrodes 420, thereby implementing the touch function of the touch electrodes 420. During a display stage, the touch sub-module 430 sequentially provides touch drive signals to some of the multiple touch signal lines 410, so that the corresponding partial touch electrodes 420 implement the touch function in each touch stage. When the display panel enters the display stage, the touch sub-module 430 stops providing touch drive signals through the touch signal lines 410. When the display panel switches back from the display stage to the touch stage, the touch sub-module 430 provides a touch drive signal to the next touch signal line 410 of the last touch signal line 410 corresponding to the previous touch stage until all the touch electrodes 420 implement the touch function.
