Description

Technical Field

[0001] The present application relates to the field of display technologies, and in particular, to a display panel and a driving method thereof. Background Art

[0002] OLED (Organic Light-Emitting Diode) display devices are widely used due to advantages such as self-luminescence, wide color gamut, low power consumption, and flexible display. Currently, in order to solve the technical problems of short lifespan and easy burn-in of blue sub-pixels in the RGB (Red, Green, Blue) standard arrangement, OLED display devices will adopt pentile arrangement or Delta arrangement. These arrangement methods enable sub-pixels to be shared among multiple pixels, which can improve the resolution of the display device, reduce the density of sub-pixels, and facilitate actual production. However, during actual use, it is found that sharing sub-pixels among pixel units will cause problems such as pixel blurring and / or edge jaggedness, affecting the display effect.

[0003] Therefore, current OLED display devices have the technical problem of being unable to balance low sub-pixel density and display effect. Summary of the Invention

[0004] Embodiments of the present application provide a display panel and a driving method thereof, so as to solve the technical problem that current OLED display devices are unable to balance low sub-pixel density and display effect.

[0005] To achieve the above object, according to the first aspect of the present application, a display panel is provided. The display panel includes a plurality of rendering units arranged in an array. Each of the rendering units includes at least three rows of sub-pixels and at least three columns of sub-pixels. In each of the rendering units, each row of the sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel with different emission colors, and each column of the sub-pixels includes the first sub-pixel, the second sub-pixel, and the third sub-pixel with different emission colors;

[0006] Wherein, a plurality of sub-pixels in each rendering unit form a plurality of pixel units. The number of the pixel units is greater than the number of sub-pixels of the same emission color, and the sub-pixels in adjacent two rendering units are independently displayed.

[0007] According to the second aspect of the present application, a driving method of a display panel is provided. The driving method of the display panel drives the display panel as described in any one of the above embodiments. The driving method of the display panel includes:

[0008] Obtaining the number of sub-pixels in a rendering unit, the composition data of sub-pixels of each pixel unit, and the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel unit;

[0009] Obtain the target sRGB values of each pixel unit of the to-be-displayed screen;

[0010] According to the target sRGB values of each pixel unit and the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel unit, determine the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel within each pixel unit;

[0011] Drive the display panel according to the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel within each pixel unit.

[0012] An embodiment of the present application provides a display panel and a driving method thereof. The display panel includes a plurality of rendering units arranged in an array. Each rendering unit includes at least three rows of sub-pixels and at least three columns of sub-pixels. Within each rendering unit, each row of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel with different emission colors, and each column of sub-pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel with different emission colors. Among them, a plurality of sub-pixels within each rendering unit form a plurality of pixel units, and the number of pixel units is greater than the number of sub-pixels of the same emission color. The sub-pixels in adjacent two rendering units are independently displayed. By making the number of pixel units within each rendering unit greater than the number of sub-pixels of the same emission color, there are shared sub-pixels within each rendering unit, thereby improving the resolution or reducing the sub-pixel density, improving the preparation efficiency and yield, and making the sub-pixels in adjacent two rendering units independently displayed, avoiding pixel blurring or edge jaggedness caused by sharing of sub-pixels in each rendering unit, improving the display effect, and thus taking into account both the low sub-pixel density and the display effect of the display panel.

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0026] Specifically, to illustrate the principle of the technical problem of the present application, some contrast display devices are provided. It can be understood that these contrast display devices cannot be regarded as the prior art of the embodiments of the present application. Specifically, when designing an OLED display device, some contrast display devices follow the design in liquid crystal display devices, and the pixel arrangement adopts the RGB standard arrangement. The RGB standard arrangement means that each pixel is composed of adjacent red sub-pixels, green sub-pixels, and blue sub-pixels. However, in actual use, it is found that the blue sub-pixels have a short lifespan and low resolution, and a high sub-pixel density will be caused to achieve high resolution.

[0027] To solve the problems existing in the contrast display device with the RGB standard arrangement, some contrast display devices adopt the pentile arrangement, that is, the area of the blue sub-pixel within a pixel is doubled to extend the lifespan. At the same time, since the human eye is more sensitive to green, in order to balance the color display effect, the area of the red sub-pixel is also increased to twice the original, so that a pixel in the pentile arrangement still consists of one red sub-pixel, one blue sub-pixel and one red sub-pixel. However, due to the change in area, the effective pixels of the pentile arrangement under the same area are about 60% of the pixels of the RGB standard arrangement, resulting in the display granularity of the contrast display device using the pentile arrangement being coarser than that of the contrast display device using the RGB standard arrangement.

[0028] Some other contrast display devices adopt the Delta arrangement. Without changing the area of each sub-pixel, compared with the RGB standard arrangement, under the same display area, the number of sub-pixels of the three colors is each reduced by one-third. Each actual pixel is arranged in RG, GB or BR, and six sub-pixels jointly surround one sub-pixel to form three to four pixel units. The actual pixel density further decreases compared with the effective pixels of the pentile arrangement. The effective pixels of the Delta arrangement under the same area are about 60% of the pixels of the RGB standard arrangement, resulting in a lower display fineness of the contrast display device using the Delta arrangement.

[0029] From the above analysis, it can be seen that the current OLED display device has the technical problem of being unable to balance low sub-pixel density and display effect.

[0030] The embodiments of the present application provide a display panel and its driving method for solving the above technical problems.

[0033] Such as Figure 1As shown in the figure, an embodiment of the present application provides a display panel. The display panel 1 includes a plurality of rendering units 11 arranged in an array. Each of the rendering units 11 includes at least three rows of sub-pixels 13 and at least three columns of sub-pixels 13. Within each of the rendering units 11, each row of the sub-pixels 13 includes a first sub-pixel 131, a second sub-pixel 132, and a third sub-pixel 133 with different emission colors, and each column of the sub-pixels 13 includes the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 with different emission colors.

[0034] Among them, a plurality of sub-pixels 13 within each rendering unit 11 form a plurality of pixel units 12. The number of the pixel units 12 is greater than the number of sub-pixels 13 of the same emission color, and the sub-pixels 13 within two adjacent rendering units 11 are independently displayed.

[0035] An embodiment of the present application provides a display panel 1. By making the number of pixel units 12 within each rendering unit 11 greater than the number of sub-pixels 13 of the same emission color, there are shared sub-pixels 13 within each rendering unit 11, so that the resolution can be improved or the sub-pixel density can be reduced, the preparation efficiency and yield can be improved, and the sub-pixels 13 within two adjacent rendering units 11 are independently displayed, avoiding pixel blurring or edge sawtooth caused by sharing of sub-pixels 13 in each rendering unit 11, improving the display effect, and thus taking into account the low sub-pixel density and display effect of the display panel.

[0036] Specifically, as Figure 1 shown in the figure, the display panel 1 includes a display area 101 and a non-display area 102, and the rendering units are arranged in the display area 101.

[0037] Specifically, it can be understood that the sub-pixel 13 includes a first sub-pixel 131, a second sub-pixel 132, or a third sub-pixel 133, which is an explanation from the type of the sub-pixel 13. The pixel unit 12 includes a first sub-pixel 131, a second sub-pixel 132, and a third sub-pixel, which is an explanation from the composition structure of the pixel unit 12, and the two do not conflict.

[0038] Specifically, the number of pixel units 12 being greater than the number of sub-pixels 13 of the same emission color means that there are shared sub-pixels 13 among the plurality of pixel units 12, making the number of pixel units 12 more than the number of sub-pixels 13 of the same emission color. For example, within a rendering unit 11, the number of first sub-pixels 131 of the same emission color is 3, the number of second sub-pixels 132 of the same emission color is 3, the number of third sub-pixels 133 of the same emission color is 3, and the number of pixel units 12 is 4, so that the number of pixel units 12 within a rendering unit 11 is greater than the number of sub-pixels 13 of the same emission color.

[0039] Specifically, the independent display of sub-pixels in two adjacent rendering units means that there is no sharing of sub-pixels between two adjacent rendering units, so that when a certain rendering unit is displayed, it does not need to borrow sub-pixels from other rendering units, and the sub-pixels in each rendering unit can be independently displayed without jointly forming a pixel unit with other rendering units for display.

[0040] Specifically, as Figure 2 , Figure 3 shown, as can be seen from Figure 2 , in a rendering unit 11, there are four pixel units 12. The pixel unit 12 includes a first pixel unit 121, a second pixel unit 122, a third pixel unit 123, and a fourth pixel unit 124. It can be seen that in a rendering unit 11, the first pixel unit 121 and the third pixel unit 123 share the first sub-pixel 131 in the second row, the second pixel unit 122 and the third pixel unit 123 share the second sub-pixel 132 in the second row, and the second pixel unit 122 and the fourth pixel unit 124 share the third sub-pixel 133; as can be seen from Figure 3 , there is no sharing of sub-pixels between each rendering unit 11. The sharing of each sub-pixel is limited to within each rendering unit 11, so as to improve the resolution or reduce the sub-pixel density, improve the preparation efficiency and yield, avoid pixel blurring or edge jaggedness caused by the sharing of sub-pixels 13 in each rendering unit 11, improve the display effect, and thus balance the low sub-pixel density and display effect of the display panel.

[0041] Specifically, to facilitate the distinction between each rendering unit, Figure 3 , in

[0042] some embodiments, as Figure 1 shown, within each rendering unit 11, the sub-pixels 13 in the first row include the second sub-pixel 132, the third sub-pixel 133, and the first sub-pixel 131 arranged in sequence; the sub-pixels 13 in the second row include the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 arranged in sequence; the sub-pixels 13 in the third row include the third sub-pixel 133, the first sub-pixel 131, and the second sub-pixel 132 arranged in sequence; when the sub-pixels in the first row and the sub-pixels in the second row form a pixel unit, the sub-pixels of different emission colors in the pixel unit are adjacent to each other, and when the sub-pixels in the second row and the sub-pixels in the third row form a pixel unit, the sub-pixels of different colors in the pixel unit are adjacent to each other, so as to improve the display effect.

[0043] Specifically, taking the emission colors of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 as red, green, and blue respectively, when the sub-pixels 13 in the first row and the sub-pixels 13 in the second row form a pixel unit 12, the sub-pixels 13 with different emission colors within the same pixel unit 12 are arranged adjacent to each other. For example, the second sub-pixel 132 in the first row, the third sub-pixel 133 in the first row, and the first sub-pixel 131 in the second row are arranged adjacent to each other and form a pixel unit 12, thereby improving the display effect.

[0044] In some embodiments, as Figure 1 shown, each of the rendering units 11 includes three rows of sub-pixels 13 and three columns of sub-pixels 13, and the three rows of sub-pixels 13 and the three columns of sub-pixels 13 form four pixel units 12. By making each rendering unit include three rows of sub-pixels 13 and three columns of sub-pixels 13, and the three rows of sub-pixels 13 and the three columns of sub-pixels 13 form four pixel units 12, the sub-pixel density of the display panel can be reduced, and there are fewer sub-pixels shared within each rendering unit, improving the display effect, thereby taking into account the low sub-pixel density and the display effect of the display panel.

[0045] Specifically, taking the resolution of the display panel as M*N as an example, a comparative display device using the RGB standard arrangement requires M*3N sub-pixels, while the embodiment of the present application only requires 1.5M*1.5N sub-pixels. At the same resolution, the sub-pixel density of the embodiment of the present application is reduced by 1 / 4, thereby reducing the sub-pixel density of the display panel, and there are no shared sub-pixels between the rendering units, improving the display effect.

[0046] In some embodiments, as Figure 1 shown, the pixel unit 12 includes a first pixel unit 121, a second pixel unit 122, a third pixel unit 123, and a fourth pixel unit 124;

[0047] Among them, within each of the rendering units 11, the second sub-pixel 132 in the first row, the third sub-pixel 133 in the first row, and the first sub-pixel 131 in the second row form a first pixel unit 121. The first sub-pixel 131 in the first row, the second sub-pixel 132 in the second row, and the third sub-pixel 133 in the second row form a second pixel unit 122. The first sub-pixel 131 in the second row, the second sub-pixel 132 in the second row, and the third sub-pixel 133 in the third row form a third pixel unit 123. The third sub-pixel 133 in the second row, the first sub-pixel 131 in the third row, and the second sub-pixel 132 in the third row form a fourth pixel unit 124. By making the sub-pixels 13 in the first row and the sub-pixels 13 in the second row form the first pixel unit 121 and the second pixel unit 122, and the sub-pixels 13 in the second row and the sub-pixels 13 in the third row form the third pixel unit 123 and the fourth pixel unit 124, the sub-pixels 13 in the second row can be shared, reducing the sub-pixel density. Moreover, the sub-pixels 13 in the first row and the sub-pixels 13 in the third row do not need to be shared, improving the display effect. Also, the sub-pixels forming each pixel unit are arranged adjacent to each other, improving the display effect.

[0048] In some embodiments, the display panel 1 is configured to determine the actual sRGB values of the sub-pixels 13 in each pixel unit 12 according to a first formula, and the first formula is:

[0049] M sRGB = k1 * R sRGB + k2 * G sRGB + k3 * B sRGB ;

[0050] Among them, M sRGB is the target sRGB value of the pixel unit, R sRGB is the actual sRGB value of the first sub-pixel of the pixel unit, G sRGB is the actual sRGB value of the second sub-pixel of the pixel unit, B sRGB is the actual sRGB value of the third sub-pixel of the pixel unit, and k1, k2, and k3 are the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of the pixel unit respectively, and k1 + k2 + k3 = 1.

[0051] Specifically, sRGB (standard Red Green Blue) is a color language protocol. The sRGB value is based on the principle of superposition and mixing of three colors: red, green, and blue. By combining the three primary colors with different intensities, various colors visible to the human eye can be generated. The display gray level of the sub-pixels of each color can be determined through the sRGB value. For example, if the value range of the sub-pixel channels of each color is from 0 to 255, then when displaying pure red at the 255th gray level, the sRGB value of a certain pixel unit is (255, 0, 0). Among them, "255" represents the component of the red sub-pixel channel of the sRGB value of this pixel unit, the first "0" represents the component of the green sub-pixel channel of the sRGB value of this pixel unit, and the second "0" represents the component of the blue sub-pixel channel of the sRGB value of this pixel unit. Similarly, when displaying pure white at the 255th gray level, the sRGB value of the pixel unit can be determined to be (255, 255, 255).

[0052] Specifically, when the display panel is displaying, due to the limitations of the manufacturing process, the sub-pixels of each emitting color cannot achieve pure color display during actual emission. For example, the sRGB value of a certain sub-pixel should be (255, 0, 0), but during actual use, the sRGB value of this sub-pixel may be (255, 25, 40). Here, "25" and "40" are just examples and do not limit the actual values to these two. Then, it can be seen that this sub-pixel cannot display the required color, resulting in a poor display effect. To address this problem, the present application corrects the actual display gray level of each sub-pixel through the first formula to improve the display effect.

[0053] Specifically, as Figure 4 shown, the mapping relationship between the non-shared sub-pixels of the comparison display device arranged according to the RGB standard and the non-shared sub-pixels of the display panel in the embodiment of the present application will be described. It can be understood that non-shared sub-pixels refer to sub-pixels that do not have sharing. Taking Figure 1 as an example, the sub-pixels 13 in the first row and the sub-pixels 13 in the third row within a rendering unit 11 are both non-shared sub-pixels, while the sub-pixels 13 in the second row are shared sub-pixels. In a comparison display device arranged according to the RGB standard, each sub-pixel is a non-shared sub-pixel.

[0054] Specifically, as Figure 4As shown, the comparison display device 2 includes a first comparison pixel unit 211, a second comparison pixel unit 212, a third comparison pixel unit 213, and a fourth comparison pixel unit 214. The first comparison pixel unit 211, the second comparison pixel unit 212, the third comparison pixel unit 213, and the fourth comparison pixel unit 214 form a pixel unit of two rows and two columns. The first comparison pixel unit 211 is regarded as the comparison pixel unit in the i-th row and the j-th column, the second comparison pixel unit 212 is regarded as the comparison pixel unit in the i-th row and the (j + 1)-th column, the third comparison pixel unit 213 is regarded as the comparison pixel unit in the (i + 1)-th row and the j-th column, and the fourth pixel unit 214 is regarded as the comparison pixel unit in the (i + 1)-th row and the (j + 1)-th column. i is greater than or equal to 1 and less than or equal to M - 1, j is equal to or equal to 1 and less than or equal to N - 1, and M and N are the number of rows and columns of the pixel units of the comparison display device, respectively.

[0055] From Figure 4 It can be seen that each comparison pixel unit includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. For example, the first comparison pixel unit 211 includes the red sub-pixel R in the i-th row and the j-th column i，j , the green sub-pixel G in the i-th row and the j-th column i，j , and the blue sub-pixel B in the i-th row and the j-th column i，j . The second comparison pixel unit 212 includes the red sub-pixel R in the i-th row and the (j + 1)-th column i，j+1 , the green sub-pixel G in the i-th row and the (j + 1)-th column i，j+1 , and the blue sub-pixel B in the i-th row and the (j + 1)-th column i，j+1 . The third comparison pixel unit 213 includes the red sub-pixel R in the (i + 1)-th row and the j-th column i+1，j , the green sub-pixel G in the (i + 1)-th row and the j-th column i+1，j , and the blue sub-pixel B in the (i + 1)-th row and the j-th column i+1，j . The fourth comparison pixel unit 214 includes the red sub-pixel R in the (i + 1)-th row and the (j + 1)-th column i+1，j+1 , the green sub-pixel G in the (i + 1)-th row and the (j + 1)-th column i+1，j+1 , and the blue sub-pixel B in the (i + 1)-th row and the (j + 1)-th column i+1，j+1 .

[0056] Taking the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the embodiments of the present application as red, green, and blue respectively, it can be seen that in the embodiments of the present application, four pixel units can be obtained by using three rows of sub-pixels and three columns of sub-pixels. Similarly, when the four pixel units are divided into two rows and two columns, the first pixel unit is the pixel unit 121 at the i-th row and the j-th column, the second pixel unit is the pixel unit 122 at the i-th row and the (j + 1)-th column, the third pixel unit 123 is the pixel unit at the (i + 1)-th row and the j-th column, and the fourth pixel unit 124 is the pixel unit at the (i + 1)-th row and the (j + 1)-th column. Similarly, it can be determined that the first pixel unit 121 includes the red sub-pixel R at the i-th row and the j-th column i，j , the green sub-pixel G at the i-th row and the j-th column i，j , and the blue sub-pixel B at the i-th row and the j-th column i，j . The second pixel unit 122 includes the red sub-pixel R at the i-th row and the (j + 1)-th column i，j+1 , the green sub-pixel G at the i-th row and the (j + 1)-th column i，j+1 , and the blue sub-pixel B at the i-th row and the (j + 1)-th column i，j+1 . Different from the comparative display device, due to the sharing of the sub-pixels in the second row, the third pixel unit 123 includes the red sub-pixel R at the i-th row and the j-th column i，j , the green sub-pixel G at the i-th row and the (j + 1)-th column i，j+1 , and the blue sub-pixel B at the (i + 1)-th row and the j-th column i+1，j . The fourth pixel unit 124 includes the red sub-pixel R at the (i + 1)-th row and the (j + 1)-th column i+1，j+1 , the green sub-pixel G at the (i + 1)-th row and the (j + 1)-th column i+1，j+1 , and the blue sub-pixel B at the i-th row and the (j + 1)-th column i，j+1 .

[0057] Then, when the display panel is displaying, the target sRGB value of the picture to be displayed is the sRGB value of the corresponding comparison pixel unit of each pixel unit. For example, the target sRGB value of the first pixel unit 121 is the sRGB value of the first comparison pixel unit 211. The sRGB value of the first comparison pixel unit 211 is composed of the values of the channels of the red sub-pixel R at the i-th row and the j-th column i，j , the green sub-pixel G at the i-th row and the j-th column i，j , and the blue sub-pixel B at the i-th row and the j-th column i，j in the first comparison pixel unit 211. In actual display, due to the limitations of the manufacturing process, there will be a difference between the actual sRGB value of the first pixel unit 121 and the target sRGB value of the first pixel unit 121, resulting in poor display

[0058] In the embodiments of the present application, through the target sRGB value of the pixel unit, that is, M sRGB, and determine the actual correction coefficient k1 of the first sub-pixel of the pixel unit, the actual correction coefficient k2 of the second sub-pixel, and the actual correction coefficient k3 of the third sub-pixel, so as to determine the actual display gray level value of each sub-pixel, thereby improving the display effect.

[0059] Specifically, k1, k2, and k3 can be obtained through pre-testing. For example, before the display panel works normally, first obtain the target sRGB value of the pixel unit of the display panel, as well as the actual sRGB value of the first sub-pixel of the pixel unit, the actual sRGB value of the second sub-pixel of the pixel unit, and the actual sRGB value of the third sub-pixel of the pixel unit, then k1, k2, and k3 can be obtained; then, when the display panel is displaying normally, the actual sRGB value of the first sub-pixel of the pixel unit, the actual sRGB value of the second sub-pixel of the pixel unit, and the actual sRGB value of the third sub-pixel of the pixel unit can be obtained through the target sRGB value of the pixel unit of the display panel and k1, k2, and k3, so as to compensate the display panel and improve the display effect.

[0060] In some embodiments, the theoretical correction coefficient of each sub-pixel 13 is determined according to the second formula, and the second formula is:

[0061] where k01, k02, and k03 are the theoretical correction coefficients of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 respectively, and each row r M , g M , b M are the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the target sRGB value of the pixel unit respectively, and r R , g R , b R are the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the first sub-pixel of the pixel unit respectively, and r G , g G , b G are the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the second sub-pixel of the pixel unit respectively, and r B , g B , b B are the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the third sub-pixel of the pixel unit respectively;

[0062] Among them, the actual correction coefficients of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 in the first row are the theoretical correction coefficients of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 in the first row; that is, the actual correction coefficient k1 of the first sub-pixel in the first row is equal to the theoretical correction coefficient k01 of the first sub-pixel in the first row, the actual correction coefficient k2 of the second sub-pixel in the first row is equal to the theoretical correction coefficient k02 of the second sub-pixel in the first row, and the actual correction coefficient k3 of the third sub-pixel in the first row is equal to the theoretical correction coefficient k03 of the second sub-pixel in the first row;

[0063] The actual correction coefficients of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 in the third row are the theoretical correction coefficients of the first sub-pixel 131, the second sub-pixel 132, and the third sub-pixel 133 in the third row; that is, the actual correction coefficient k1 of the first sub-pixel in the third row is equal to the theoretical correction coefficient k01 of the first sub-pixel in the first row, the actual correction coefficient k2 of the second sub-pixel in the third row is equal to the theoretical correction coefficient k02 of the second sub-pixel in the first row, and the actual correction coefficient k3 of the third sub-pixel in the third row is equal to the theoretical correction coefficient k03 of the second sub-pixel in the first row;

[0064] The actual correction coefficient of the first sub-pixel 131 in the second row is one-half of the sum of the theoretical correction coefficient of the first sub-pixel 131 of the first pixel unit 121 and the theoretical correction coefficient of the first sub-pixel 131 of the third pixel unit 123; that is, the actual correction coefficient k1 of the first sub-pixel 131 in the second row is equal to one-half of the sum of the theoretical correction coefficient k01 of the first sub-pixel 131 of the first pixel unit 121 and the theoretical correction coefficient k01 of the first sub-pixel 131 of the third pixel unit 123 (the theoretical correction coefficient k01 of the first sub-pixel 131 of the first pixel unit 121 and the theoretical correction coefficient k01 of the first sub-pixel 131 of the third pixel unit 123 can be different or the same);

[0065] The actual correction coefficient of the second sub-pixel 132 in the second row is one-half of the sum of the theoretical correction coefficient of the second sub-pixel 132 of the second pixel unit 122 and the theoretical correction coefficient of the second sub-pixel 132 of the third pixel unit 123; that is, the actual correction coefficient k2 of the second sub-pixel 132 in the second row is equal to one-half of the sum of the theoretical correction coefficient k02 of the second sub-pixel 132 of the second pixel unit 122 and the theoretical correction coefficient k02 of the second sub-pixel 132 of the third pixel unit 123 (the theoretical correction coefficient k02 of the second sub-pixel 132 of the second pixel unit 122 and the theoretical correction coefficient k02 of the second sub-pixel 132 of the third pixel unit 123 can be different or the same);

[0066] The actual correction coefficient of the third sub-pixel 133 in the second row is one half of the sum of the theoretical correction coefficients of the third sub-pixel 133 of the second pixel unit 122 and the third sub-pixel 133 of the fourth pixel unit 124; that is, the actual correction coefficient k3 of the third sub-pixel 133 in the second row is one half of the sum of the theoretical correction coefficient k03 of the third sub-pixel 133 of the second pixel unit 122 and the theoretical correction coefficient k03 of the third sub-pixel 133 of the fourth pixel unit 124 (the theoretical correction coefficient k03 of the third sub-pixel 133 of the second pixel unit 122 and the theoretical correction coefficient k03 of the third sub-pixel 133 of the fourth pixel unit 124 may be different or the same).

[0067] Specifically, it can be understood that the actual correction coefficient of the first sub-pixel in the second row is the actual correction coefficient of the first sub-pixel in the first pixel unit, and the actual correction coefficient of the first sub-pixel in the second row is the actual correction coefficient of the first sub-pixel in the third pixel unit. Similarly, the actual correction coefficient of the second sub-pixel in the second row is the actual correction coefficient of the second sub-pixel in the second pixel unit, and the actual correction coefficient of the second sub-pixel in the second row is the actual correction coefficient of the second sub-pixel in the second pixel unit. Similarly, the actual correction coefficient of the third sub-pixel in the second row is the actual correction coefficient of the third sub-pixel in the second pixel unit, and the actual correction coefficient of the third sub-pixel in the second row is the actual correction coefficient of the third sub-pixel in the fourth pixel unit.

[0068] Specifically, considering the sharing of sub-pixels in the second row, the actual correction coefficients of the sub-pixels in the second row are determined according to the two pixel units of the shared sub-pixels, which can improve the correction effect. Since there is no sharing of sub-pixels in the first row and the third row, the actual correction coefficients of different sub-pixels can be determined according to the mapping of each sub-pixel to the comparison pixel unit of the comparison display device, improving the correction effect.

[0069] Specifically, M sRGB =(r M , g M , b M ), that is, the target sRGB value of the pixel unit is composed of the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the target sRGB value of the pixel unit. For example, when the display panel is displaying, the target sRGB value of the first pixel unit is determined by the sRGB value of the corresponding first comparison pixel unit. The sRGB value of the first comparison pixel unit is composed of the components of its three sub-pixel channels. Taking the first comparison pixel unit displaying a pure white picture with a gray scale of 255 as an example, the sRGB value of the first comparison pixel unit is (255, 255, 255). Correspondingly, the target sRGB value of the first pixel unit is (255, 255, 255).

[0070] Specifically, R sRGB = (r R , g R , b R ), that is, the actual sRGB value of the first sub-pixel of the pixel unit is composed of the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the first sub-pixel of the pixel unit. Similarly, G sRGB = (r G , g G , b G ), the actual sRGB value of the second sub-pixel of the pixel unit is composed of the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the second sub-pixel of the pixel unit. B sRGB = (r B , g B , b B ), the actual sRGB value of the third sub-pixel of the pixel unit is composed of the components of the first sub-pixel channel, the second sub-pixel channel, and the third sub-pixel channel of the actual sRGB value of the third sub-pixel of the pixel unit.

[0071] Specifically, it can be understood that taking the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel as red, green, and blue respectively as an example, for the sub-pixels in the first row and the third row, k01, k02, and k03 obtained according to the second formula are k1, k2, and k3. For example, the green sub-pixel in the first row is the sub-pixel in the first pixel unit, and this sub-pixel has no sharing. The theoretical correction coefficients k02 and k03 of the green sub-pixel in the first row are determined by the sRGB value of the first comparison pixel unit, the sRGB value of the red sub-pixel of the first pixel unit, the sRGB value of the green sub-pixel of the first pixel unit, and the sRGB value of the blue sub-pixel of the first pixel unit. Then, the theoretical correction coefficients k2 and k3 of the green sub-pixel in the first row are respectively the theoretical correction coefficients k02 and k03 of the green sub-pixel in the first row. The red sub-pixel in the first pixel unit and the red sub-pixel in the third pixel unit share the red sub-pixel in the second row. Then, the actual correction coefficient of the red sub-pixel in the second row is: one-half of the sum of the theoretical correction coefficient of the red sub-pixel in the first pixel unit and the theoretical correction coefficient of the first sub-pixel in the third pixel unit. Thus, the correction coefficients of the sub-pixels in each row can be determined, improving the display effect.

[0072] Specifically, after calculating the obtained R sRGB , G sRGB , BsRGB When there is a negative number in it, make it 0. In the calculated R sRGB 、G sRGB 、B sRGB When there is a value greater than 255 in it, make it 255. In the calculated R sRGB 、G sRGB 、B sRGB When there is a non-integer in it, make it take a value by rounding.

[0085] Meanwhile, the embodiments of the present application provide a driving method for a display panel, and the driving method for the display panel drives the display panel according to any one of the above embodiments.

[0086] In some embodiments, as Figure 5 shown, the driving method for the display panel includes:

[0087] S1, obtaining the number of sub-pixels in the rendering unit, the composition data of the sub-pixels of each pixel unit, and the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel unit;

[0088] S2, obtaining the target sRGB values of each pixel unit of the picture to be displayed;

[0089] S3, determining the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel in each pixel unit according to the target sRGB values of each pixel unit and the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel unit;

[0090] S4, driving the display panel according to the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel in each pixel unit.

[0091] Specifically, the composition data of the sub-pixels of each pixel unit includes data such as the number of sub-pixels, the emission color of the sub-pixels, and the position of the sub-pixels. For example, the composition data of the sub-pixels of the first pixel unit includes: the first pixel unit is composed of one first sub-pixel, one second sub-pixel, and one third sub-pixel, and further includes: the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the first pixel unit, and further includes: the set positions of the first sub-pixel, the second sub-pixel, and the third sub-pixel in the first pixel unit. For example, the first sub-pixel in the first pixel unit is set in the first row and the first column.

[0092] An embodiment of the present application provides a driving method for a display panel. The driving method of the display panel determines the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel in each pixel unit according to the target sRGB value of each pixel unit and the actual correction coefficients of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel unit, and drives the display panel according to the actual sRGB values of the first sub-pixel, the second sub-pixel, and the third sub-pixel in each pixel unit, which can improve the display effect.

[0093] Specifically, taking the display panel in Figure 1 as an example, when a comparative display device with a Delta arrangement and the display panel in the embodiment of the present application display different pictures, the corresponding MSE values and PSNRs are shown in the following table:

[0094] Table 1. Comparison table of MSE and PSNR corresponding to the comparative display device with a Delta arrangement and the display panel in the embodiment of the present application when displaying different pictures

[0095]

[0096] Among them, "correction" means determining the actual sRGB values of the sub-pixels of the display panel through the target sRGB value of each pixel unit and the actual correction coefficients of each sub-pixel, and driving the display panel in the embodiment of the present application with the actual sRGB values. "No correction" means directly inputting the sRGB values of each sub-pixel to drive the display panel in the embodiment of the present application. It can be understood that although the effect of "no correction" is relatively poor, it is still a driving method in the embodiment of the present application; "MSE" means the mean square value of the pixel value differences between the image displayed by the comparative display device with an RGB standard arrangement and the image displayed by the display panel with other arrangements; "PSNR" means the ratio of the maximum possible signal intensity of the image to the noise (error) intensity, with the unit of dB, that is, decibel.

[0097] Specifically, for the patterns of "white ring", "white diagonal line", "colored letter", and "flower pattern" in the display picture, reference can be made to Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 6 . The (a) in Figure 6 . The (b) in Figure 6 . The (c) in Figure 6 are the theoretical display pictures when displaying the white ring, the comparative display device with a Delta arrangement, the display panel in the embodiment of the present application driven by the corrected actual sRGB values, and the display panel in the embodiment of the present application driven by the uncorrected sRGB values when displaying the white ring, respectively.Figure 7 (a) in Figure 7 (b) in Figure 7 (c) in Figure 7 and (d) in are the theoretical display pictures when showing white diagonal slashes, the comparative display device adopting the Delta arrangement, the display panel in the embodiment of the present application driven by the corrected actual sRGB value, and the picture showing white diagonal slashes when the display panel in the embodiment of the present application is driven by the uncorrected sRGB value, Figure 8 (a) in Figure 8 (b) in Figure 8 (c) in Figure 8 and (d) in are the theoretical display pictures when showing colored letters, the comparative display device adopting the Delta arrangement, the display panel in the embodiment of the present application driven by the corrected actual sRGB value, and the picture showing colored letters when the display panel in the embodiment of the present application is driven by the uncorrected sRGB value; Figure 9 (a) in Figure 9 (b) in Figure 9 (c) in Figure 9 and (d) in are the theoretical display pictures when showing flower patterns, the comparative display device adopting the Delta arrangement, the display panel in the embodiment of the present application driven by the corrected actual sRGB value, and the picture showing flower patterns when the display panel in the embodiment of the present application is driven by the uncorrected sRGB value.

[0098] As can be seen from Table 1, for simple patterns, such as white rings and white diagonal slashes, the display effect when the display panel in the embodiment of the present application is driven by the uncorrected sRGB value is similar to that of the comparative display device adopting the Delta arrangement. For complex patterns, such as colored letters and flower patterns, the display effect when the display panel in the embodiment of the present application is driven by the uncorrected sRGB value is better than that of the comparative display device adopting the Delta arrangement. And for any pattern, the display effect when the display panel in the embodiment of the present application is driven by the corrected actual sRGB value is better than that of the comparative display device adopting the Delta arrangement, indicating that the embodiment of the present application achieves the effects of reducing the sub-pixel density and improving the display effect.

[0100] Meanwhile, an embodiment of the present application provides a display device, which includes a display panel, a memory, a processor, and a computer program stored on the memory and executable on the processor.

It can be understood that when there is no conflict among the embodiments, the embodiments can be combined. For example, the emission colors of the first sub-pixel, the second sub-pixel, and the third sub-pixel are red, green, and blue respectively, and the area of the first sub-pixel is equal to the area of the second sub-pixel, and the area of the first sub-pixel is equal to the area of the second sub-pixel.
