Description

Technical Field

[0001] This application relates to the field of display technology, specifically to a display device and a subpixel rendering method. Background Technology

[0002] Organic light-emitting diode (OLED) display panels offer advantages over liquid crystal displays, including thinner and lighter designs, better display quality, higher resolution, wider color gamut, lower power consumption, and the ability to achieve flexible displays. These advantages have led to their rapid development in recent years, making them the preferred display panel type for many display applications.

[0003] Inkjet printing is a common process for manufacturing OLED display panels. Compared to vapor deposition, it offers advantages such as higher material utilization and lower manufacturing costs. Currently, users' demands for OLED display panel resolution are gradually increasing. However, due to the precision limitations of inkjet printing equipment, OLED display panels manufactured using this process still suffer from resolution issues that fail to meet user requirements.

[0004] In related technologies, in order to reduce the precision requirements of inkjet printing equipment while achieving high resolution, researchers have proposed changing the pixel structure targeted by inkjet printing from the conventional pixel structure to a 2-in-1 pixel structure. In the 2-in-1 pixel structure, two adjacent sub-pixels share one ink droplet and display the same color. However, the 2-in-1 pixel structure is prone to causing color fringing on the display panel, which affects the user experience. This problem urgently needs to be solved. Summary of the Invention

[0062] Example 1

[0063] Combination Figures 1-4bAs shown, in a first aspect, Embodiment 1 of this application provides a display device M1, which includes a display panel M2 and a driving chip M3. The display panel M2 includes a plurality of pixel units 10 arranged sequentially in a first direction X and a second direction Y. The first direction X intersects the second direction Y. Each pixel unit 10 includes three sub-pixels, namely a first sub-pixel 101, a second sub-pixel 102, and a third sub-pixel 103. In one pixel unit 10, the first sub-pixel 101 is disposed on the side where the second sub-pixels 102 and the third sub-pixels 103 face the second direction Y. In a pixel unit 10 adjacent to one of the pixel units 10, the first sub-pixel 101 is disposed on the side where the second sub-pixels 102 and the third sub-pixels 103 face away from the second direction Y. Each first sub-pixel 101 is adjacent to a second sub-pixel 102 on the side facing the first direction X, and is adjacent to a third sub-pixel 103 on the side facing away from the first direction X; the driving chip M3 is electrically connected to the display panel M2, and the driving chip M3 includes a first brightness module M31 and a sub-pixel rendering module M32. The first brightness module M31 outputs the first brightness of a specific sub-pixel in the target pixel unit 11 and the first brightness of a specific sub-pixel in each pixel unit 10 around the target pixel unit 11 to the sub-pixel rendering module M32. The specific sub-pixel includes the second sub-pixel 102 and the third sub-pixel 103; the sub-pixel rendering module M32 recalculates the brightness of the specific sub-pixel in the target pixel unit 11 to output the second brightness of the specific sub-pixel in the target pixel unit 11.

[0064] In the display panel provided in this application, the sub-pixel rendering module M32 can recalculate the brightness of the second sub-pixel 102 and the third sub-pixel 103 in the target pixel unit 11 to output the second brightness of the second sub-pixel 102 and the third sub-pixel 103 in the target pixel unit 11, thereby improving the color edge effect and enhancing the display effect of the display panel.

[0065] Specifically, since the first sub-pixel 101 in one of the pixel units 10 is located on the side facing the second sub-pixel 102 and the third sub-pixel 103, and the first sub-pixel 101 in the pixel unit 10 adjacent to the one of the pixel units 10 is located on the side facing the second sub-pixel 102 and the third sub-pixel 103 away from the second direction Y, and each first sub-pixel 101 is adjacent to a second sub-pixel 102 on the side facing the first direction X, and each first sub-pixel 101 is adjacent to a third sub-pixel 103 on the side away from the first direction X, that is, in the display panel M2 provided in this application, the first sub-pixel 101 in each pixel unit 10 is not located between the second sub-pixel 102 and the third sub-pixel 103, but the human eye's color mixing effect is based on the first sub-pixel 101 as the center point for color mixing, this makes the display panel M2 prone to color fringing effect when displayed, resulting in a decrease in the display quality of the display panel M2.

[0066] In the display panel M2 provided in this application, the specific sub-pixel includes the second sub-pixel 102 and the third sub-pixel 103. That is, this application can render the brightness of the second sub-pixel 102 and the third sub-pixel 103 in the target pixel unit 11 through the sub-pixel rendering module M32, so that after rendering, the second sub-pixel 102 in the pixel unit 10 surrounding the target pixel unit 11 and the third sub-pixel 103 in the pixel unit 10 surrounding the target pixel unit 11 can be color-mixed with the first sub-pixel 101 in the target pixel unit 11, so as to satisfy the human eye's color mixing effect as much as possible.

[0067] In some embodiments of this application, the sub-pixel rendering module M32 recalculates the brightness of a specific sub-pixel in the target pixel unit 11 according to a rendering calculation matrix table M321, so as to output the second brightness of the specific sub-pixel in the target pixel unit 11; wherein, the rendering calculation matrix table M321 includes a plurality of calculation blocks 20, the second brightness of the specific sub-pixel in the target pixel unit 11 is equal to the sum of the values ​​of the plurality of calculation blocks 20, and the value of each calculation block 20 is obtained by multiplying the first brightness of the specific sub-pixel of the target pixel unit 11 and one of the pixel units 10 surrounding the target pixel unit 11 by a compensation coefficient, and at least two of the plurality of calculation blocks 20 have values ​​greater than 0.

[0068] In the display panel M2 provided in this application, the sub-pixel rendering module M32 can render the target pixel unit 11 by performing rendering processing on the target pixel unit 11 based on the first brightness of a specific sub-pixel in the target pixel unit 11 output by the first brightness module M31 and the first brightness of each sub-pixel in each pixel unit 10 surrounding the target pixel unit 11, so that the specific sub-pixel in the target pixel unit 11 has a second brightness, thereby improving the color edge effect of the display panel M2 and improving the display effect of the display panel M2.

[0069] Specifically, since the second brightness of a specific sub-pixel in the target pixel unit 11 is equal to the sum of the values ​​of multiple calculation blocks 20, and the value of each calculation block 20 is obtained by multiplying the first brightness of a specific sub-pixel in the target pixel unit 11 and one of the pixel units 10 surrounding the target pixel unit 11 by a compensation coefficient, and the values ​​of at least two of the multiple calculation blocks 20 are greater than 0, the second brightness of a specific sub-pixel in the target pixel unit 11 can be affected by the first brightness of a specific sub-pixel in at least two pixel units 10, thereby improving the uneven color mixing problem caused by the sub-pixel arrangement in the target pixel unit 11, improving the color edge effect of the display panel M2, and improving the display quality of the display panel M2 when displaying the color corresponding to the second sub-pixel 102.

[0070] In some embodiments of this application, the first sub-pixel 101 is a green sub-pixel, the second sub-pixel 102 is one of a red sub-pixel and a blue sub-pixel, and the third sub-pixel 103 is the other of a red sub-pixel and a blue sub-pixel.

[0071] In the display panel M2 provided in this application, green contributes the most to the brightness of pixel unit 10. The color mixing effect of the human eye is based on the green sub-pixel as the center point for color mixing. This application sets the first sub-pixel 101 as a green sub-pixel, the second sub-pixel 102 as one of a red sub-pixel and a blue sub-pixel, and the third sub-pixel 103 as the other of a red sub-pixel and a blue sub-pixel. This enables the sub-pixel rendering module M32 to effectively render the brightness of the red and blue sub-pixels, thereby improving the color edge effect and enhancing the display effect of the display panel M2.

[0072] In some embodiments of this application, the first sub-pixel 101 in each pixel unit 10 shares a pixel definition opening with the first sub-pixel 101 in an adjacent pixel unit 10, the second sub-pixel 102 in each pixel unit 10 shares a pixel definition opening with the second sub-pixel 102 in an adjacent pixel unit 10, and the third sub-pixel 103 in each pixel unit 10 shares a pixel definition opening with the third sub-pixel 103 in an adjacent pixel unit 10.

[0073] In the display panel M2 provided in this application, since the first sub-pixel 101 in each pixel unit 10 shares a pixel definition opening with the first sub-pixel 101 in an adjacent pixel unit 10, the second sub-pixel 102 in each pixel unit 10 shares a pixel definition opening with the second sub-pixel 102 in an adjacent pixel unit 10, and the third sub-pixel 103 in each pixel unit 10 shares a pixel definition opening with the third sub-pixel 103 in an adjacent pixel unit 10, the display panel M2 can achieve this by having two adjacent sub-pixels of the same color share an inkjet printing pit during inkjet printing without increasing the precision of the inkjet printing equipment or the number of pixel definition openings, thereby improving the resolution of the display panel M2.

[0074] In some embodiments of this application, the display panel M2 has a display area AA, and the target pixel unit 11 is spaced at least one pixel unit 10 from any edge AA1 of the display area AA. The pixel units 10 surrounding the target pixel unit 11 include a second pixel unit 12, a third pixel unit 13, a fourth pixel unit 14, a fifth pixel unit 15, a sixth pixel unit 16, a seventh pixel unit 17, an eighth pixel unit 18, and a ninth pixel unit 19 arranged sequentially in a clockwise direction. The second pixel unit 12 is disposed in the target pixel unit M2. 1. The side facing the first direction X; the plurality of calculation blocks 20 includes a target calculation block 21, and a second calculation block 22, a third calculation block 23, a fourth calculation block 24, a fifth calculation block 25, a sixth calculation block 26, a seventh calculation block 27, an eighth calculation block 28, and a ninth calculation block 29 arranged sequentially in a clockwise direction around the target calculation block 21, wherein the second calculation block 22 is located on the side of the target calculation block 21 facing the first direction X; wherein, the target calculation block 21, the second calculation block 22, the third calculation block 23, the fourth calculation block 24... The first brightness of a specific sub-pixel in the fifth calculation block 25, the sixth calculation block 26, the seventh calculation block 27, the eighth calculation block 28, and the ninth calculation block 29 corresponds to the first brightness of a specific sub-pixel in the target pixel unit 11, the second pixel unit 12, the third pixel unit 13, the fourth pixel unit 14, the fifth pixel unit 15, the sixth pixel unit 16, the seventh pixel unit 17, the eighth pixel unit 18, and the ninth pixel unit 19, respectively; when the specific sub-pixel is the second sub-pixel 102, the compensation coefficient of the second sub-pixel 102 of the target calculation block 21 is... k1, the compensation coefficient of the second sub-pixel 102 of the sixth calculation block 26 is k2, k1 and k2 are both greater than 0, and the sum of k1 and k2 is equal to 1, and the compensation coefficient of the second sub-pixel 102 of the other calculation blocks 20 is 0; when the specific sub-pixel is the third sub-pixel 103, the compensation coefficient of the third sub-pixel 103 of the target calculation block 21 is k1, the compensation coefficient of the third sub-pixel 103 of the second calculation block 22 is k2, k1 and k2 are both greater than 0, and the sum of k1 and k2 is equal to 1, and the compensation coefficient of the third sub-pixel 103 of the other calculation blocks 20 is 0.

[0075] In the display panel M2 provided in this application, when the specific sub-pixel is the second sub-pixel 102, the compensation coefficients of the second sub-pixels 102 in the other calculation blocks 20, except for the target calculation block 21 and the sixth calculation block 26, are all 0. That is, when rendering compensation is performed on the second sub-pixel 102 in the target pixel unit 11, only the first brightness of the second sub-pixel 102 in the target pixel unit 11 corresponding to the target calculation block 21 and the first brightness of the second sub-pixel 102 in the sixth pixel unit 16 corresponding to the sixth calculation block 26 affect the second brightness of the second sub-pixel 102 in the target calculation block 21. Brightness is affected; similarly, since when the specific sub-pixel is the third sub-pixel 103, except for the target calculation block 21 and the second calculation block 22, the compensation coefficient of the third sub-pixel 103 of the other calculation blocks 20 is 0. That is, when rendering compensation is performed on the third sub-pixel 103 in the target pixel unit 11, only the first brightness of the third sub-pixel 103 in the target pixel unit 11 corresponding to the target calculation block 21 and the first brightness of the third sub-pixel 103 in the second pixel unit 12 corresponding to the second calculation block 22 affect the second brightness of the third sub-pixel 103 in the target calculation block 21. In summary, when rendering compensation is applied to the second sub-pixel 102 and the third sub-pixel 103 in the target pixel unit 11, the second sub-pixel 102 in the target pixel unit 11 can be shared by the target pixel unit 11 and the sixth pixel unit 16, and the third sub-pixel 103 in the target pixel unit 11 can be shared by the target pixel unit 11 and the second pixel unit 12. This allows the target pixel unit 11 to better reflect the color mixing effect of the human eye during display, thereby improving the display effect of the display panel M2, and simplifying the rendering calculation rules.

[0076] In some embodiments of this application, k1 is 3 / 4 and k2 is 1 / 4.

[0077] In some embodiments of this application, the first brightness of the second sub-pixel 102 in the target pixel unit 11 is A1; the first brightness of the second sub-pixel 102 in the second pixel unit 12 is A2; the first brightness of the second sub-pixel 102 in the third pixel unit 13 is A3; the first brightness of the second sub-pixel 102 in the fourth pixel unit 14 is A4; the first brightness of the second sub-pixel 102 in the fifth pixel unit 15 is A5; the first brightness of the second sub-pixel 102 in the sixth pixel unit 16 is A6; the first brightness of the second sub-pixel 102 in the seventh pixel unit 17 is A7; the first brightness of the second sub-pixel 102 in the eighth pixel unit 18 is A8; and the first brightness of the second sub-pixel 102 in the ninth pixel unit 19 is A9. Therefore, the second brightness of the second sub-pixel 102 in the target pixel unit 11 is the sum of the product of A1 and k1 and the product of A6 and k2.

[0078] In some embodiments of this application, the first brightness of the third sub-pixel 103 in the target pixel unit 11 is B1; the first brightness of the third sub-pixel 103 in the second pixel unit 12 is B2; the first brightness of the third sub-pixel 103 in the third pixel unit 13 is B3; the first brightness of the third sub-pixel 103 in the fourth pixel unit 14 is B4; the first brightness of the third sub-pixel 103 in the fifth pixel unit 15 is B5; the first brightness of the third sub-pixel 103 in the sixth pixel unit 16 is B6; the first brightness of the third sub-pixel 103 in the seventh pixel unit 17 is B7; the first brightness of the third sub-pixel 103 in the eighth pixel unit 18 is B8; and the first brightness of the third sub-pixel 103 in the ninth pixel unit 19 is B9. Therefore, the second brightness of the third sub-pixel 103 in the target pixel unit 11 is the sum of the product of B1 and k1 and the product of B2 and k2.

[0079] In some embodiments of this application, the specific sub-pixel does not include the first sub-pixel 101.

[0080] In the display panel M2 provided in this application, the specific sub-pixel does not include the first sub-pixel 101. That is, the sub-pixel rendering module M32 does not recalculate and adjust the brightness of the first sub-pixel 101 in the target pixel unit 11. Alternatively, it can be considered that the second brightness of the first sub-pixel 101 in the target pixel unit 11 is the first brightness of the first sub-pixel 101 in the target pixel unit 11 output by the first brightness module M31.

[0081] Combination Figure 5 , Figure 6a , Figure 6bAs shown, in some embodiments of this application, the display panel M2 has a display area AA, and the target pixel unit 11 is adjacent to the edge AA1 of the display area AA. The first brightness of a specific sub-pixel in at least two of the plurality of calculation blocks 20 corresponds to the first brightness of a specific sub-pixel in the same pixel unit 10.

[0082] In the display panel M2 provided in this application, since the target pixel unit 11 is adjacent to the edge AA1 of the display area AA, the number of pixel units 10 surrounding the target pixel unit 11 is less than eight. That is, when the plurality of calculation blocks 20 include a target calculation block 21, a second calculation block 22, a third calculation block 23, a fourth calculation block 24, a fifth calculation block 25, a sixth calculation block 26, a seventh calculation block 27, an eighth calculation block 28, and a ninth calculation block 29, and the target calculation block 21 corresponds to the target pixel unit 11, the number of pixel units 10 surrounding the target pixel unit 11 is less than eight. 8. If at least one calculation block 20 in the ninth calculation block 29 cannot correspond one-to-one with the pixel units 10 surrounding the target pixel unit 11, in this case, the first brightness of a specific sub-pixel in at least two of the plurality of calculation blocks 20 corresponds to the first brightness of a specific sub-pixel in the same pixel unit 10, so as to copy and extend the first brightness of at least one specific sub-pixel in the calculation block 20, so as to avoid the problem that the first brightness of a specific sub-pixel in the calculation block 20 is determined to be 0 because the target pixel unit 11 is adjacent to the edge AA1 of the display area AA, which leads to the problem that the second brightness of the specific sub-pixel in the target pixel unit 11 is low after rendering.

[0083] In some embodiments of this application, there are no other computation blocks 20 between two computation blocks 20 that correspond to the first brightness of a specific sub-pixel in the same pixel unit 10.

[0084] Taking the target pixel unit 11 located at the upper left corner of the display area AA as an example, after copying and expanding the first brightness of a specific sub-pixel in at least one of the calculation blocks 20, the first brightness of the second sub-pixel 102 in the target pixel unit 11 is A1; the first brightness of the second sub-pixel 102 in the second pixel unit 12 is A2; the first brightness of the second sub-pixel 102 in the third pixel unit 13 is A3; the first brightness of the second sub-pixel 102 in the fourth pixel unit 14 is A4; the first brightness of the second sub-pixel 102 in the fifth pixel unit 15 is A4; the first brightness of the second sub-pixel 102 in the sixth pixel unit 16 is A1; the first brightness of the second sub-pixel 102 in the seventh pixel unit 17 is A1; and the first brightness of the second sub-pixel 102 in the eighth pixel unit 18 is A1. The first brightness of the second sub-pixel 102 in the ninth pixel unit 19 is A2; the first brightness of the third sub-pixel 103 in the target pixel unit 11 is B1; the first brightness of the third sub-pixel 103 in the second pixel unit 12 is B2; the first brightness of the third sub-pixel 103 in the third pixel unit 13 is B3; the first brightness of the third sub-pixel 103 in the fourth pixel unit 14 is B4; the first brightness of the third sub-pixel 103 in the fifth pixel unit 15 is B4; the first brightness of the third sub-pixel 103 in the sixth pixel unit 16 is B1; the first brightness of the third sub-pixel 103 in the seventh pixel unit 17 is B1; the first brightness of the third sub-pixel 103 in the eighth pixel unit 18 is B1; and the first brightness of the third sub-pixel 103 in the ninth pixel unit 19 is B2.

[0085] It should be noted that the copied and extended content does not include the compensation coefficient of specific sub-pixels. In some embodiments of this application, the compensation coefficient of specific sub-pixels in the target calculation block 21, the second calculation block 22, the third calculation block 23, the fourth calculation block 24, the fifth calculation block 25, the sixth calculation block 26, the seventh calculation block 27, the eighth calculation block 28, and the ninth calculation block 29 remains unchanged. That is, when the specific sub-pixel is the second sub-pixel 102, the compensation coefficient of the second sub-pixel 102 of the target calculation block 21 is k1, the compensation coefficient of the second sub-pixel 102 of the sixth calculation block 26 is k2, and the compensation coefficient of the second sub-pixel 102 of the remaining calculation blocks 20 is 0; when the specific sub-pixel is the third sub-pixel 103, the compensation coefficient of the third sub-pixel 103 of the target calculation block 21 is k1, the compensation coefficient of the third sub-pixel 103 of the second calculation block 22 is k2, and the compensation coefficient of the third sub-pixel 103 of the remaining calculation blocks 20 is 0.

The subpixel rendering method is used to drive a plurality of pixel units 10 of a display panel. The display panel M2 includes a plurality of pixel units 10 arranged sequentially in a first direction X and a second direction Y. The first direction X intersects the second direction Y. Each pixel unit 10 includes three subpixels, namely a first subpixel 101, a second subpixel 102, and a third subpixel 103. The first subpixel 101 in one pixel unit 10 is disposed on the side of the second subpixel 102 and the third subpixel 103 facing the second direction Y. The first subpixel 101 in the pixel unit 10 adjacent to the first pixel unit 10 is disposed on the side of the second subpixel 102 and the third subpixel 103 away from the second direction Y. Each first subpixel 101 is adjacent to a second subpixel 102 on the side facing the first direction X, and each first subpixel 101 is adjacent to a third subpixel 103 on the side away from the first direction X.

[0087] The sub-pixel rendering method includes the following steps:

[0088] Acquire the position information of the target pixel unit 11 and the first brightness of a specific sub-pixel in the target pixel unit 11, and the first brightness of a specific sub-pixel in each pixel unit 10 surrounding the target pixel unit 11, wherein the specific sub-pixel includes a second sub-pixel 102 and a third sub-pixel 103;

[0089] The brightness of a specific sub-pixel in the target pixel unit 11 is recalculated according to a rendering calculation matrix table M321 to output the second brightness of the specific sub-pixel in the target pixel unit 11.

[0090] The rendering calculation matrix table M321 includes multiple calculation blocks 20. The second brightness of a specific sub-pixel in the target pixel unit 11 is equal to the sum of the values ​​of the multiple calculation blocks 20. The value of each calculation block 20 is obtained by multiplying the first brightness of a specific sub-pixel in the target pixel unit 11 and one of the pixel units 10 surrounding the target pixel unit 11 by a compensation coefficient. The values ​​of at least two of the multiple calculation blocks 20 are greater than 0.

[0091] In some embodiments of this application, the specific sub-pixel includes the second sub-pixel 102 and the third sub-pixel 103, but does not include the first sub-pixel 101.

[0092] In some embodiments of this application, when the position information of the target pixel unit 11 is obtained such that there is at least one pixel unit 10 between the target pixel unit 11 and any edge AA1 of the display area AA, the step of recalculating the brightness of a specific sub-pixel in the target pixel unit 11 according to a rendering calculation matrix table M321 to output the second brightness of the specific sub-pixel in the target pixel unit 11 includes:

The compensation coefficient of the second sub-pixel 102 in the target calculation block 21 is k1, the compensation coefficient of the second sub-pixel 102 in the sixth calculation block 26 is k2, both k1 and k2 are greater than 0, and the sum of k1 and k2 is equal to 1. The compensation coefficient of the second sub-pixel 102 in the remaining calculation blocks 20 is 0.

[0094] The brightness of the third sub-pixel 103 in the target pixel unit 11 is recalculated. The compensation coefficient of the third sub-pixel 103 in the target calculation block 21 is k1, the compensation coefficient of the third sub-pixel 103 in the second calculation block 22 is k2, both k1 and k2 are greater than 0, and the sum of k1 and k2 is equal to 1. The compensation coefficient of the third sub-pixel 103 in the remaining calculation blocks 20 is 0.

[0095] In some embodiments of this application, when the position information of the target pixel unit 11 is obtained as being adjacent to the edge AA1 of the display area AA, the step of recalculating the brightness of a specific sub-pixel in the target pixel unit 11 according to a rendering calculation matrix table M321 to output the second brightness of the specific sub-pixel in the target pixel unit 11 includes:

[0096] The first brightness of a specific sub-pixel in at least two of the plurality of computation blocks 20 is made to correspond to the first brightness of a specific sub-pixel in the same pixel unit 10, so as to copy and extend the first brightness of at least one specific sub-pixel in the computation block 20, so as to avoid the problem that the first brightness of a specific sub-pixel in the computation block 20 is determined to be 0 because the target pixel unit 11 is adjacent to the edge AA1 of the display area AA, which leads to the problem that the second brightness of the specific sub-pixel in the target pixel unit 11 after rendering is low.
