Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, in particular to a display device and a driving method of a display panel. BACKGROUND

[0002] mini-LED, as a direct illumination backlight of liquid crystal display (LCD), is emerging. The mini-LED LCD can achieve a contrast ratio and thickness comparable to OLED displays through large-area local dimming. In addition, the advantages of long durability, high peak brightness and mature technology of traditional LCD are also well preserved. Therefore, in the field of micro displays in tablets, laptops, televisions, headphones and the like, mini-LED LCD is attracting much attention. However, mini-LED LCD has a similar disadvantage to traditional LCD, that is, the existence of color filter array (CFA) will absorb at least two-thirds of the backlight, resulting in low light efficiency. In order to improve the light efficiency of liquid crystal display and save the power consumption of display to the maximum, the field sequential color (FSC) liquid crystal display emerges as the times require.

[0003] FSC display technology is to form the superposition of colors on the retina of the human eye by applying the visual persistence of the human eye and by the rapid flashing of red, green and blue subframes (i.e. fields) of the backlight, to present a color image. Because FSC-LCD does not need sub-pixels, the resolution of FSC-LCD can reach three times that of ordinary LCD under the same panel size. In addition, mini-LED FSC-LCD is also a superior display technology with low power consumption, high resolution, high contrast ratio and high brightness, which can perfectly meet the needs of the next generation of applications such as VR and AR.

[0004] However, the current FSC-LCD has a color breakup (CBU) problem which greatly hinders its application. That is, when the viewer's eyes scan or smoothly pursue the moving objects on the FSC-LCD, that is, when there is a relative speed between the viewer's eyes and the screen, the fields of view of different primary colors cannot be perfectly superimposed on the retina. This incomplete color superposition will cause the boundary of the figure to be blurred to form red, green and blue color stripes, affecting the display effect. SUMMARY

[0005] Therefore, the main purpose of the present application is to propose a display device and a driving method of a display panel, aiming to solve the problem of color breakup existing in the current mini-LED FSC-LCD.

[0069] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort belong to the scope of protection of the present application.

[0070] Furthermore, the terms "first", "second", and the like in the description of the application are used for distinguishing between similar objects and not necessarily for describing a sequential or chronological order. It is to be understood that the data so distinguished can be interchanged under appropriate circumstances such that the embodiments of the application described herein can be practiced in other than the illustrated or described order. Additionally, the terms "comprising", "including", "having" and the like are intended to be open ended and mean that there can be additional steps or elements other than those listed, and that these steps or elements do not need to be mutually exclusive.

[0071] It should be noted that the features of the embodiments of the application can be combined with each other, without conflict.

[0072] Please refer to Figures 1-3 The display device 100 includes a display panel 10 and a driving circuit 20.

[0073] The display panel 10 includes a plurality of pixel units P, each of which includes a pixel electrode 11.

[0074] Each of the pixel electrodes 11 includes a main pixel electrode 111 and a plurality of compensation pixel electrodes. The main pixel electrode 111 includes opposite first and second sides, and the plurality of compensation pixel electrodes includes a plurality of first compensation sub-electrodes 112 and a plurality of second compensation sub-electrodes 113. The plurality of first compensation sub-electrodes 112 are arranged at intervals on the first side of the main pixel electrode 111, and the plurality of second compensation sub-electrodes 113 are arranged at intervals on the second side of the main pixel electrode 111. The main pixel electrode 111 and all the first compensation sub-electrodes 112 together form a first sub-electrode group, the main pixel electrode 111 and the adjacent part of the first compensation sub-electrodes 112 and the adjacent part of the second compensation sub-electrodes 113 together form a second sub-electrode group, and the main pixel electrode 111 and all the second compensation sub-electrodes 113 together form a third sub-electrode group.

[0075] The display period of a frame picture of the display panel 10 includes a first sub-frame period, a second sub-frame period and a third sub-frame period performed in sequence, and the frame picture includes a first sub-frame picture, a second sub-frame picture and a third sub-frame picture correspondingly. The driving circuit 20 is configured to drive the display panel 10 to display the first sub-frame picture in the first sub-frame period, the second sub-frame picture in the second sub-frame period and the third sub-frame picture in the third sub-frame period.

[0076] The driving circuit 20 is configured to determine a first target sub-electrode group, a second target sub-electrode group and a third target sub-electrode group from the first sub-electrode group, the second sub-electrode group and the third sub-electrode group according to the movement of the user's line of sight landing point on the display panel 10. The driving circuit 20 is further configured to output a corresponding first data voltage to the first target sub-electrode group of each pixel unit P in the first sub-frame period, so that the display panel 10 displays the first sub-frame picture, and output a corresponding second data voltage to the second target sub-electrode group of each pixel unit P in the second sub-frame period, so that the display panel 10 displays the second sub-frame picture, and output a corresponding third data voltage to the third target sub-electrode group of each pixel unit P in the third sub-frame period, so that the display panel 10 displays the third sub-frame picture.

[0077] The display device 100 provided by the present application can make the pixel unit P light at positions following the movement of the user's line of sight in three sub-frame periods by dividing the pixel electrode 11 of each pixel unit P into a main pixel electrode 111, a plurality of first compensation sub-electrodes 112 located on the first side of the main pixel electrode 111, and a plurality of second compensation sub-electrodes 113 located on the second side of the main pixel electrode 111, and by forming a first sub-electrode group with the main pixel electrode 111 and all the first compensation sub-electrodes 112, a second sub-electrode group with the main pixel electrode 111 and adjacent partial first compensation sub-electrodes 112 and adjacent partial second compensation sub-electrodes 113, and a third sub-electrode group with the main pixel electrode 111 and all the second compensation sub-electrodes 113, and by the driving circuit 20 outputting a corresponding pixel voltage to the corresponding sub-electrode group in each sub-frame period according to the movement of the user's line of sight landing point on the display panel 10. Thus, the problem of incomplete superposition of different primary colors caused by movement of the human eye can be alleviated, and the user's visual experience can be improved.

[0078] Please refer to Figure 3 , Figure 3 For the sectional view of the pixel unit P along the tangent A-A, as shown in Figure 3 The display panel 10 includes an array substrate 1, an opposite substrate 2 arranged opposite to the array substrate, and a liquid crystal layer 3 arranged between the array substrate 1 and the opposite substrate 2. The pixel electrode 11 is arranged on the side of the first substrate 12 of the array substrate 1 close to the liquid crystal layer 3.

[0079] The array substrate 1 can further include a first metal layer M1, a gate insulating layer Gi / A SI, an active layer, a second metal layer M2, a passivation layer PV1, an organic planarization layer PFA, and the like, which will not be described one by one here. The opposite substrate 2 includes a second substrate 21 and a common electrode 22 disposed on the side of the second substrate 21 close to the liquid crystal layer 3.

[0080] The display device 100 further includes a backlight module 30 located on the side of the array substrate 1 away from the liquid crystal layer 3, and a plurality of light emitting elements 31 are disposed on the backlight module 30. The light emitting elements 31 are used to emit first primary color light in the first subframe period, second primary color light in the second subframe period, and third primary color light in the third subframe period. The first primary color, the second primary color, and the third primary color can be red R, green G, and blue B, respectively. That is, the display panel 10 displays a red subframe picture in the first subframe period, a green subframe picture in the second subframe period, and a blue subframe picture in the third subframe period. The light emitting elements 31 can be LEDs, mini-LEDs, micro-LEDs, and the like.

[0081] In any of the first subframe period to the third subframe period, when a pixel unit P is scanned, the common electrode 22 in the pixel unit P is used to receive a common voltage, and the pixel electrode 11 in the pixel unit P is used to receive a data voltage corresponding to the pixel unit P. As a result, an electric field with an intensity corresponding to the data voltage is generated between the pixel electrode 11 and the common electrode 22, which drives the liquid crystal molecules in the liquid crystal layer 3 between the pixel electrode 11 and the common electrode 22 to deflect to an angle corresponding to the data voltage, so that part of the light emitted by the light emitting element 31 transmits through the liquid crystal layer 3, and the pixel unit P displays a target gray scale corresponding to the data voltage.

[0082] In some embodiments, the total area of the first sub-electrode group, the total area of the second sub-electrode group, and the total area of the third sub-electrode group are equal.

[0083] The total area of ​​the first sub-electrode group refers to the total area of ​​the projection of the first sub-electrode group onto the display surface of the display panel 10. It is easy to understand that the total area of ​​the sub-electrode group determines the area illuminated by the pixel unit P. Setting the total areas of the first, second, and third sub-electrode groups to be equal ensures that the display area of ​​the same pixel unit P is equal from the first sub-frame period to the third sub-frame period. This means that the illuminated area of ​​a pixel unit P is equal from the first sub-frame period to the third sub-frame period, allowing for better superposition of different primary colors within a single frame, resulting in a better display effect.

[0084] Furthermore, the number of the plurality of first compensating sub-electrodes 112 is equal to the number of the plurality of second compensating sub-electrodes 113. The area of ​​each first compensating sub-electrode 112 is equal to the area of ​​each second compensating sub-electrode 113.

[0085] Furthermore, the number of compensation sub-electrodes (including first compensation sub-electrode 112 and second compensation sub-electrode 113) in the second sub-electrode group is equal to the number of the plurality of first compensation sub-electrodes 112.

[0086] For example, such as Figure 2 As shown, the number of the plurality of first compensation sub-electrodes 112 and the number of the plurality of second compensation sub-electrodes 113 are both 2. The first compensation sub-electrodes 112, the main pixel electrode 111, and the plurality of second compensation sub-electrodes 113 are all strips extending along the column direction and along the row direction (e.g., ...). Figure 2 The electrodes are arranged at intervals along the X-axis (as shown). The second sub-electrode group includes the main pixel electrode 111, an adjacent first compensation sub-electrode 112, and an adjacent second compensation sub-electrode 113. In this embodiment, in each sub-electrode group, the main pixel electrode 111 undertakes the primary lighting task, while the compensation sub-electrodes (including the first compensation sub-electrode 112 and the second compensation sub-electrode 113) provide misalignment compensation. Therefore, the area of ​​the main pixel electrode 111 is larger than the area of ​​each compensation pixel electrode. Of course, in other embodiments, the number of the plurality of first compensation sub-electrodes 112 and the plurality of second compensation sub-electrodes 113 can also be other, for example, 3, 4, 5, etc.

[0087] like Figure 4 As shown, in some other embodiments, the first compensation sub-electrode 112, the main pixel electrode 111, and the plurality of second compensation sub-electrodes 113 are all strips extending along the row direction and along the column direction (e.g., ...). Figure 2 (As shown in the X-axis direction) arranged at intervals.

[0088] In the embodiment of the present application, the display device 100 further comprises an eye detection module (not shown in the figure) electrically connected with the driving circuit 20, the eye detection module is used to acquire the activity state of the eyeball of the user, so as to obtain the visual line landing point of the user on the display panel, and output the visual line landing point information to the driving circuit 20, so that the driving circuit 20 can determine the movement of the visual line landing point of the user on the display panel according to the visual line landing point information.

[0092] The third switch tube T3 comprises a first connection end and a second connection end, the first connection end of the third switch tube T3 is electrically connected with the driving circuit 20, and the second connection end of the third switch tube T3 is electrically connected with each sub-electrode in the third sub-electrode group in the present pixel unit P. When the third switch tube T3 is turned on, the driving circuit 20 can output the corresponding data voltage to the third sub-electrode group through the turned-on third switch tube T3.

[0093] Each of the sub-electrodes in each of the sub-electrode groups refers to the main pixel electrode 111 and any of the corresponding compensation sub-electrodes, for example, each of the sub-electrodes in the first sub-electrode group refers to the main pixel electrode 111 and any of all the first compensation sub-electrodes 112.

[0094] Exemplarily, the first switch tube T1, the second switch tube T2 and the third switch tube T3 can adopt at least one of a triode or a MOS tube, for example, all are NMOS tubes.

[0095] Thus, in different sub-frame periods, different sub-electrode groups can output corresponding data voltages by controlling the on-off states of the first switch tube T1, the second switch tube T2 and the third switch tube T3.

[0096] Further, the display panel 10 further includes a plurality of scan lines extending along the row direction and arranged along the column direction and electrically connected with the driving circuit 20, the plurality of scan lines include a plurality of groups of scan lines, each group of scan lines includes a first scan line, a second scan line and a third scan line. The plurality of pixel units P are arranged in a multi-row and multi-column array, each row of pixel units corresponds to a group of scan lines.

[0097] The first switch tube T1, the second switch tube T2 and the third switch tube T3 each include a control terminal, the control terminal of the first switch tube T1 is electrically connected with the first scan line corresponding to the current pixel unit P, the first switch tube T1 is used to receive the first scan signal output by the driving circuit 20 through the first scan line and turn on in response to the first scan signal. The control terminal of the second switch tube T2 is electrically connected with the second scan line corresponding to the current pixel unit P, the second switch tube T2 is used to receive the second scan signal output by the driving circuit 20 through the second scan line and turn on in response to the second scan signal. The control terminal of the third switch tube T3 is electrically connected with the third scan line corresponding to the current pixel unit P, the third switch tube T3 is used to receive the third scan signal output by the driving circuit 20 through the third scan line and turn on in response to the third scan signal.

[0098] Exemplarily, as Figures 1-2As shown, taking the first row of pixel units in the display panel 10 as an example, the first row of pixel units corresponds to a first group of scan lines (including a first scan line G11, a second scan line G12, and a third scan line G13). Specifically, the control end of the first switch tube T1 of all pixel units P in the first row of pixel units is electrically connected with the first scan line G11, the control end of the second switch tube T2 of all pixel units P in the second row of pixel units is electrically connected with the second scan line G12, and the control end of the third switch tube T3 of all pixel units P in the third row of pixel units is electrically connected with the third scan line G13.

[0099] In this way, the driving circuit can control the on-off state of the first switch tube T1, the second switch tube T2, and the third switch tube T3 in each row of pixel units through the plurality of groups of scan lines.

[0100] Further, the display panel 10 further includes a plurality of data lines extending along the column direction and arranged at intervals along the row direction and electrically connected with the driving circuit 20. Each data line corresponds to a column of pixel units. Each data line is electrically connected with the first connection end of the first switch tube T1, the first connection end of the second switch tube T2, and the first connection end of the third switch tube T3 of each pixel unit P in the corresponding column of pixel units. The driving circuit 20 is configured to output corresponding data voltages to each pixel unit P through the plurality of data lines.

[0101] For example, as shown, Figures 1-2 As shown, taking the first row of pixel units in the display panel 10 as an example, the first row of pixel units corresponds to a first group of scan lines (including a first scan line G11, a second scan line G12, and a third scan line G13). Specifically, the control end of the first switch tube T1 of all pixel units P in the first row of pixel units is electrically connected with the first scan line G11, the control end of the second switch tube T2 of all pixel units P in the second row of pixel units is electrically connected with the second scan line G12, and the control end of the third switch tube T3 of all pixel units P in the third row of pixel units is electrically connected with the third scan line G13.

[0102] In this embodiment, the driving circuit 20 is configured to drive the multiple sets of scan lines to scan the multiple rows of pixel units line by line during a first subframe period to output corresponding first data voltages to the first target sub-electrode group of the multiple rows of pixel units line by line, drive the multiple sets of scan lines to scan the multiple rows of pixel units line by line during a second subframe period to output corresponding second data voltages to the second target sub-electrode group of the multiple rows of pixel units line by line, and drive the multiple sets of scan lines to scan the multiple rows of pixel units line by line during a third subframe period to output corresponding third data voltages to the third target sub-electrode group of the multiple rows of pixel units line by line.

[0103] Taking the first subframe as an example, driving the multiple sets of scan lines to scan multiple rows of pixel units line by line during the first subframe means driving the multiple sets of scan lines to scan the first row of pixel units to the last row of pixel units sequentially, from the first set of scan lines to the last set of scan lines. Specifically, scanning a row of pixel units during the first subframe means controlling the switching transistors corresponding to the first target sub-electrode group in that row of pixel units to be turned on by outputting a corresponding scan signal through the scan line corresponding to the first target sub-electrode group.

[0104] For example, such as Figure 1 As shown, the driving circuit 20 includes a scan driving circuit 201 and a data driving circuit 202. The scan driving circuit 201 is electrically connected to the plurality of scan lines and is used to output corresponding first scan line numbers, second scan signals, and third scan signals to the plurality of scan lines. The data driving circuit 202 is electrically connected to the plurality of data lines and is used to output corresponding data voltages to the plurality of data lines.

[0105] In this embodiment of the application, when the driving circuit 20 scans each row of pixel units in the first subframe time period, it operates sequentially in the first scanning sub-time period t1 and the second scanning sub-time period t2.

[0106] The driving circuit 20 is used to output a first scanning signal to the first scanning line corresponding to the row of pixel units, a second scanning signal to the second scanning line corresponding to the row of pixel units, and a third scanning signal to the third scanning line corresponding to the row of pixel units during the first scanning sub-period t1 when scanning a row of pixel units. This controls the first switching transistor T1, the second switching transistor T2, and the third switching transistor T3 of the row of pixel units to be turned on, thereby outputting an initialization data voltage V0 to the pixel electrode 11 of the row of pixel units, so that the row of pixel units displays the initial grayscale.

[0107] The driving circuit 20 is also configured to output a corresponding scanning signal to a first target scanning line corresponding to a row of pixel units in a second scanning sub-period t2 for scanning the row of pixel units, so as to control a first target switch tube of the row of pixel units to be turned on, thereby outputting a corresponding first data voltage to a first target sub-electrode group of the row of pixel units. The first target switch tube is a switch tube of the first switch tube T1, the second switch tube T2 and the third switch tube T3 which is electrically connected to the first target sub-electrode group, and the first target scanning line is a scanning line of the first scanning line, the second scanning line and the third scanning line which is electrically connected to the first target switch tube. For example, when the first sub-electrode group is the first target sub-electrode group, the first switch tube T1 is the first target switch tube, and the first scanning line is the first target scanning line.

[0108] Exemplarily, the initial gray scale is a gray scale L0, i.e. a black picture.

[0109] In this way, in the first scanning sub-period t1 for scanning the row of pixel units, the first switch tube T1, the second switch tube T2 and the third switch tube T3 of the row of pixel units are all turned on, and the initialization data voltage V0 is output to the pixel electrode 11 of the row of pixel units, so that the row of pixel units can be initialized, and the influence of the data voltage of the previous frame picture on the current frame picture is avoided.

[0110] In the embodiments of the present application, the driving circuit 20 works in the third scanning sub-period t3 and the fourth scanning sub-period t4 in turn when scanning each row of pixel units in the second sub-frame period.

[0111] The driving circuit 20 is configured to output a first scanning signal to a first scanning line corresponding to a row of pixel units in a third scanning sub-period t3 for scanning the row of pixel units, output a second scanning signal to a second scanning line corresponding to the row of pixel units, and output a third scanning signal to a third scanning line corresponding to the row of pixel units, so as to control the first switch tube T1, the second switch tube T2 and the third switch tube T3 of the row of pixel units to be turned on, thereby outputting the initialization data voltage V0 to the pixel electrode 11 of the row of pixel units, and further making the row of pixel units all display the initial gray scale.

[0112] The driving circuit 20 is also configured to output a corresponding scanning signal to a second target scanning line corresponding to a row of pixel units during a fourth scanning sub-period t4 for scanning the row of pixel units, so as to control a second target switch tube of the row of pixel units to be turned on, thereby outputting a corresponding second data voltage to a second target sub-electrode group of the row of pixel units. The second target switch tube is a switch tube of the first switch tube T1, the second switch tube T2 and the third switch tube T3 which is electrically connected to the second target sub-electrode group, and the second target scanning line is a scanning line of the first scanning line, the second scanning line and the third scanning line which is electrically connected to the second target switch tube. For example, when the second sub-electrode group is the second target sub-electrode group, the second switch tube T2 is the second target switch tube, and the second scanning line is the second target scanning line.

[0113] In this way, during the third scanning sub-period t3 for scanning the row of pixel units, the first switch tube T1, the second switch tube T2 and the third switch tube T3 of the row of pixel units are all controlled to be turned on, and the initialization data voltage V0 is output to the pixel electrode 11 of the row of pixel units, so that the row of pixel units can be initialized, and the influence of the data voltage of the first sub-frame picture on the second sub-frame picture is avoided.

[0114] In the embodiments of the present application, the driving circuit 20 works in the fifth scanning sub-period t5 and the sixth scanning sub-period t6 in turn when scanning each row of pixel units in the third sub-frame period.

[0115] The driving circuit 20 is configured to output a first scanning signal to a first scanning line corresponding to a row of pixel units, output a second scanning signal to a second scanning line corresponding to the row of pixel units, and output a third scanning signal to a third scanning line corresponding to the row of pixel units during a fifth scanning sub-period t5 for scanning the row of pixel units, so as to control the first switch tube T1, the second switch tube T2 and the third switch tube T3 of the row of pixel units to be turned on, thereby outputting the initialization data voltage V0 to the pixel electrode 11 of the row of pixel units, and further making the row of pixel units all display the initial gray scale.

[0116] The driving circuit 20 is further configured to output a corresponding scanning signal to the third target scan line corresponding to the row of pixel units during the sixth scanning sub-period t6 of scanning a row of pixel units, thereby controlling the third target switch transistor of the row of pixel units to be turned on, and thus outputting a corresponding third data voltage to the third target sub-electrode group of the row of pixel units. The third target switch transistor is one of the first switch transistor T1, the second switch transistor T2, and the third switch transistor T3 that is electrically connected to the third target sub-electrode group, and the third target scan line is one of the first scan line, the second scan line, and the third scan line that is electrically connected to the third target switch transistor. For example, when the third sub-electrode group is the third target sub-electrode group, then the third switch transistor T3 is the third target switch transistor, and the third scan line is the third target scan line.

[0117] Thus, during the fifth scanning sub-period t5 when scanning a row of pixel units, the first switch T1, the second switch T2, and the third switch T3 of the row of pixel units are all turned on, and initialization data voltage V0 is output to the pixel electrode 11 of the row of pixel units. This can initialize the row of pixel units and prevent the residual data voltage of the second sub-frame from affecting the third sub-frame.

[0118] In some embodiments, when a user's gaze on the display panel 10 moves along a first preset direction, the driving circuit 20 determines the first sub-electrode group as the first target sub-electrode group, the second sub-electrode group as the second target sub-electrode group, and the third sub-electrode group as the third target sub-electrode group. The first preset direction is the direction from the first side of the main pixel electrode 111 to the second side.

[0119] Specifically, for ease of description, the embodiments of this application will list directions ( Figure 2 The Y-axis direction shown is called the vertical direction, and the row direction is called the horizontal direction. Figure 2 The X-axis direction shown is called the left-right direction, such as... Figure 2 As shown, the first side of the main pixel electrode 111 is the left side, and the second side of the main pixel electrode 111 is the right side. The first preset direction is from left to right, and the second preset direction is from right to left. In other embodiments, the first side of the main pixel electrode 111 may be the right side, and the second side may be the left side, or as shown... Figure 4 As shown, the first side of the main pixel electrode 111 is the lower side and the second side is the upper side, or the first side of the main pixel electrode 111 is the upper side and the second side is the lower side.

[0120] The following is combined Figures 5-9The workflow of a pixel unit P during the display cycle of one frame of an image as the user's gaze moves along a first preset direction on the display panel is described in detail. Figure 5 for Figure 1 The timing diagram of some of the drive signals of the display device 100 during the display cycle of one frame is shown. Figure 6 for Figure 2 The diagram shown illustrates the circuitry of pixel unit P during the first scan sub-period t1, the third scan sub-period t3, and the fifth scan sub-period t5.

[0121] like Figure 6 As shown, for pixel unit P located in the first row and first column, during the first sub-scanning period t1 of the first sub-frame period, the first switch T1, the second switch T2, and the third switch T3 are turned on under the drive of the first scan line G11, the second scan line G12, and the third scan line G13, respectively. As a result, each sub-electrode of pixel unit P receives the initial data voltage V0 output by data line D1, and thus pixel unit P displays the initial grayscale during the first scanning period t1.

[0122] like Figure 7 As shown, for pixel unit P located in the first row and first column, during the second scan sub-scanning period t2 of the first sub-frame period when pixel unit P is scanned, the first switch T1 is turned on under the drive of the first scan line G11, so that the first sub-electrode group of pixel unit P receives the first data voltage V111 output by data line D1 through the turned-on first switch T1. At this time, the second switch T2 and the third switch T3 are both turned off.

[0123] Similarly, during the first sub-frame period, the first sub-electrode groups in other pixel units P of the display panel 10 receive the first data voltage output by the corresponding data line through the corresponding first switch transistor T1, thereby the display panel 10 displays the first sub-frame image during the first sub-frame period.

[0124] like Figure 6As shown, for the pixel unit P located at the first row and the first column, in the third scanning sub-period t3 of scanning the pixel unit P in the second sub-frame period, the first switch tube T1, the second switch tube T2 and the third switch tube T3 are turned on under the driving of the first scanning line G11, the second scanning line G12 and the third scanning line G13 respectively, so that each sub-electrode of the pixel unit P receives the initialization data voltage V0 output by the data line D1, and the pixel unit P displays the initial gray scale in the third scanning sub-period t3.

[0125] As shown in FIG. 4, for the pixel unit P located at the first row and the first column, in the fourth scanning sub-period t4 of scanning the pixel unit P in the second sub-frame period, the second switch tube T2 is turned on under the driving of the second scanning line G12, so that the second sub-electrode group of the pixel unit P receives the second data voltage V112 output by the data line D1 through the turned-on second switch tube T2. At this time, the first switch tube T1 and the third switch tube T3 are both turned off. Figure 8

[0126] Similarly, in the second sub-frame period, the second sub-electrode group in each of the other pixel units P in the display panel 10 receives the second data voltage output by the corresponding data line through the corresponding second switch tube T2, so that the display panel 10 displays the second sub-frame picture in the second sub-frame period.

[0127] As shown in FIG. 5, for the pixel unit P located at the first row and the first column, in the fifth scanning sub-period t5 of scanning the pixel unit P in the third sub-frame period, the first switch tube T1, the second switch tube T2 and the third switch tube T3 are turned on under the driving of the first scanning line G11, the second scanning line G12 and the third scanning line G13 respectively, so that each sub-electrode of the pixel unit P receives the initialization data voltage V0 output by the data line D1, and the pixel unit P displays the initial gray scale in the fifth scanning sub-period t5. Figure 6

[0128] As shown in FIG. 6, for the pixel unit P located at the first row and the first column, in the sixth scanning sub-period t6 of scanning the pixel unit P in the third sub-frame period, the third switch tube T3 is turned on under the driving of the third scanning line G13, so that the third sub-electrode group of the pixel unit P receives the third data voltage V113 output by the data line D1 through the turned-on third switch tube T3. At this time, the first switch tube T1 and the second switch tube T2 are both turned off. Figure 9

[0129] ​​​Similarly, in the third sub-frame period, the third sub-electrode group in other pixel units P in the display panel 10 all receive the third data voltage output by the corresponding data line through the corresponding third switch tube T3, so that the display panel 10 displays the third sub-frame picture in the third sub-frame period.

[0130] In some embodiments, when the visual line landing point of the user on the display panel 10 moves along a second preset direction, the driving circuit 20 determines the third sub-electrode group as the first target sub-electrode group, determines the second sub-electrode group as the second target sub-electrode group, and determines the first sub-electrode group as the third target sub-electrode group. Wherein, the second preset direction is a direction in which the second side of the main pixel electrode 111 points to the first side.

[0131] Specifically, when the visual line landing point of the user on the display panel 10 moves along a second preset direction, the driving circuit 20 is configured to output a corresponding first data voltage to the third sub-electrode group of each pixel unit P in the first sub-frame period, so that the display panel 10 displays a first sub-frame picture in the third sub-frame period, and output a corresponding second data voltage to the second sub-electrode group of each pixel unit P in the second sub-frame period, so that the display panel 10 displays a second sub-frame picture in the second sub-frame period, and output a corresponding third data voltage to the first sub-electrode group of each pixel unit P in the third sub-frame period, so that the display panel 10 displays a third sub-frame picture in the third sub-frame period.

[0132] In some embodiments, when the visual line landing point of the user on the display panel 10 is fixed, the driving circuit 20 simultaneously determines one of the first sub-electrode group, the second sub-electrode group and the third sub-electrode group as the first target sub-electrode group, the second target sub-electrode group and the third target sub-electrode group.

[0133] Exemplarily, when the user's line of sight landing point on the display panel 10 is fixed, the driving circuit 20 simultaneously determines the second sub-electrode group as the first target sub-electrode group, the second target sub-electrode group and the third target sub-electrode group.

[0134] Based on the same inventive concept, the present application also provides a driving method of a display panel. The display panel 10 includes a plurality of pixel units P. A display period of a frame picture of the display panel 10 includes a first sub-frame period, a second sub-frame period and a third sub-frame period performed in sequence. The frame picture corresponds to a first sub-frame picture, a second sub-frame picture and a third sub-frame picture. The display panel 10 displays the first sub-frame picture in the first sub-frame period, displays the second sub-frame picture in the second sub-frame period, and displays the third sub-frame picture in the third sub-frame period. Each pixel unit P includes a pixel electrode 11.

The plurality of second compensation sub-electrodes 113 are arranged at intervals on the second side of the main pixel electrode 111. The main pixel electrode 111 and all the first compensation sub-electrodes 112 together form a first sub-electrode group. The main pixel electrode 111, the adjacent part of the first compensation sub-electrodes 112 and the adjacent part of the second compensation sub-electrodes 113 together form a second sub-electrode group. The main pixel electrode 111 and all the second compensation sub-electrodes 113 together form a third sub-electrode group.
