Description

Display device and sub-pixel rendering method Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display device and a sub-pixel rendering method. Background Art

[0002] Compared with liquid crystal displays, organic light-emitting diode (OLED) display panels have the advantages of being thinner and lighter, having better display effects, higher resolution, wider color gamut, lower power consumption, and flexible display. As a result, they have developed rapidly in recent years and have become the preferred display panel type in many display applications.

[0003] Inkjet printing is a common process for producing OLED display panels. Compared to vapor deposition, it offers advantages such as high material utilization and low production costs. Currently, users are increasingly demanding higher resolution OLED display panels. However, due to the precision limitations of inkjet printing equipment, OLED display panels produced using inkjet printing still have a resolution that fails to meet user demands.

[0004] In related technologies, in order to achieve high resolution while reducing the requirements of the inkjet printing process for equipment precision, researchers have proposed changing the pixel structure targeted by inkjet printing from a conventional pixel structure to a 2in1 pixel structure. The two adjacent sub-pixels in the 2in1 pixel structure share one ink droplet and display the same color. However, the 2in1 pixel structure is prone to color edge phenomenon on the display panel, affecting the user experience. This problem needs to be solved urgently. SUMMARY OF THE INVENTION

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, and 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.

[0072] In the display panel provided in the present 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 improving the display effect of the display panel.

[0073] Specifically, since the first sub-pixel 101 in one of the pixel units 10 is arranged on the side of the second sub-pixel 102 and the third sub-pixel 103 facing the second direction Y, the first sub-pixel 101 in the pixel unit 10 adjacent to one of the pixel units 10 is arranged on the side of the second sub-pixel 102 and the third sub-pixel 103 away from the second direction Y, and each of the first sub-pixels 101 is adjacent to a second sub-pixel 102 on the side facing the first direction X, and each of the first sub-pixels 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 the present application, the first sub-pixel 101 in each pixel unit 10 is not arranged between the second sub-pixel 102 and the third sub-pixel 103, but the color mixing effect of the human eye is to mix colors with the first sub-pixel 101 as the center point, which makes it easy for the display panel M2 to have a color edge effect during display, resulting in a decrease in the display quality of the display panel M2.

[0074] In the display panel M2 provided in the present application, the specific sub-pixels include the second sub-pixel 102 and the third sub-pixel 103, that is, the present 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 around the target pixel unit 11 and the third sub-pixel 103 in the pixel unit 10 around the target pixel unit 11 can be mixed in color with the first sub-pixel 101 in the target pixel unit 11 to satisfy the color mixing effect of the human eye as much as possible.

[0075] In some embodiments of the present 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 to output a second brightness of the specific sub-pixel in the target pixel unit 11; wherein the rendering calculation matrix table M321 includes multiple 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 multiple calculation blocks 20, and the value of each of the calculation blocks 20 is obtained by multiplying the first brightness of a specific sub-pixel in the target pixel unit 11 and the pixel units 10 around 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.

[0076] In the display panel M2 provided in the present application, the sub-pixel rendering module M32 can render the target pixel unit 11 according to the first brightness of the 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 around 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.

[0077] Specifically, since the second brightness of the 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 the pixel units 10 around the target pixel unit 11 by a compensation coefficient, and the values ​​of at least two calculation blocks 20 among the multiple calculation blocks 20 are greater than 0, the second brightness of the specific sub-pixel in the target pixel unit 11 can be affected by the first brightness of the specific sub-pixels 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.

[0078] In some embodiments of the present 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.

[0079] In the display panel M2 provided by the present application, green contributes the most to the brightness of the pixel unit 10, and the color mixing effect of the human eye is to mix colors with the green sub-pixel as the center point. The present application sets the first sub-pixel 101 to a green sub-pixel, the second sub-pixel 102 to one of the red sub-pixel and the blue sub-pixel, and the third sub-pixel 103 to the other of the red sub-pixel and the blue sub-pixel, so that the sub-pixel rendering module M32 can effectively render the brightness of the red sub-pixel and the blue sub-pixel, thereby improving the color edge effect and improving the display effect of the display panel M2.

[0080] In some embodiments of the present application, the first sub-pixel 101 in each of the pixel units 10 shares a pixel-defining opening with the first sub-pixel 101 in an adjacent pixel unit 10, the second sub-pixel 102 in each of the pixel units 10 shares a pixel-defining opening with the second sub-pixel 102 in an adjacent pixel unit 10, and the third sub-pixel 103 in each of the pixel units 10 shares a pixel-defining opening with the third sub-pixel 103 in an adjacent pixel unit 10.

[0081] In the display panel M2 provided in the present 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, during the inkjet printing process, enable two adjacent sub-pixels of the same color to share an inkjet printing pit without increasing the accuracy of the inkjet printing equipment and the number of pixel definition openings, thereby improving the resolution of the display panel M2.

[0082] In some embodiments of the present application, the display panel M2 has a display area AA, and there is at least one pixel unit 10 between the target pixel unit 11 and any edge AA1 of the display area AA. The pixel units 10 around 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 in a clockwise direction, and the second pixel unit 12 is arranged on the target pixel unit 11. 1 is on the side facing the first direction X; the plurality of calculation blocks 20 include 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 in a clockwise direction around the target calculation block 21, wherein the second calculation block 22 is arranged on the side facing the first direction X of the target calculation block 21; 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 the specific sub-pixels 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 respectively correspond to the first brightness of the specific sub-pixels 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; 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 coefficients of the second sub-pixels 102 of the remaining calculation blocks 20 are all 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, and 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 coefficients of the third sub-pixels 103 of the remaining calculation blocks 20 are all 0.

[0083] In the display panel M2 provided in the present application, since when the specific sub-pixel is the second sub-pixel 102, except for the target calculation block 21 and the sixth calculation block 26, the compensation coefficients of the second sub-pixels 102 of the remaining calculation blocks 20 are all 0, that is, when the second sub-pixel 102 in the target pixel unit 11 is rendered and compensated, 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 are used to compensate the second sub-pixel 102 in the target calculation block 21. Similarly, 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 coefficients of the third sub-pixels 103 of the remaining calculation blocks 20 are all 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 have an impact on the second brightness of the third sub-pixel 103 in the target calculation block 21. In summary, when rendering compensation is performed on 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, so that the target pixel unit 11 can be more in line with the human eye color mixing effect when displaying, thereby improving the display effect of the display panel M2, and the rendering calculation rules are simpler.

[0084] In some embodiments of the present application, k1 is 3 / 4, and k2 is 1 / 4.

[0085] In some embodiments of the present 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; the first brightness of the second sub-pixel 102 in the ninth pixel unit 19 is A9; then, 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.

[0086] In some embodiments of the present 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; the first brightness of the third sub-pixel 103 in the ninth pixel unit 19 is B9; then, 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.

[0087] In some embodiments of the present application, the specific sub-pixel does not include the first sub-pixel 101 .

[0088] In the display panel M2 provided in the present 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, or, 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.

[0089] In combination with Figures 5, 6a, and 6b, in some embodiments of the present application, the display panel M2 has a display area AA, the target pixel unit 11 is adjacent to the edge AA1 of the display area AA, wherein the first brightness of a specific sub-pixel in at least two of the multiple calculation blocks 20 corresponds to the first brightness of a specific sub-pixel in the same pixel unit 10.

[0090] In the display panel M2 provided in the present application, since the target pixel unit 11 is adjacent to the edge AA1 of the display area AA, the number of pixel units 10 around the target pixel unit 11 is less than eight, that is, when the multiple 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 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. 8.

In this case, the first brightness of the specific sub-pixels in at least two calculation blocks 20 among the multiple calculation blocks 20 corresponds to the first brightness of the specific sub-pixels in the same pixel unit 10, so as to copy and expand the first brightness of the specific sub-pixels in at least one of the calculation blocks 20, thereby avoiding the problem that the first brightness of the specific sub-pixels in the calculation block 20 is judged to be 0 due to the target pixel unit 11 being adjacent to the edge AA1 of the display area AA, thereby resulting in a lower second brightness of the specific sub-pixels in the rendered target pixel unit 11.

[0091] In some embodiments of the present application, no other calculation blocks 20 are interposed between two calculation blocks 20 corresponding to the first brightness of a specific sub-pixel in the same pixel unit 10 .

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.

[0093] It should be noted that the copied and extended content does not include the compensation coefficient of the specific sub-pixel. In some embodiments of the present application, the compensation coefficient of the specific sub-pixel 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 coefficients of the second sub-pixels 102 of the remaining calculation blocks 20 are all 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 coefficients of the third sub-pixels 103 of the remaining calculation blocks 20 are all 0.

[0099] In some embodiments of the present application, the specific sub-pixels include the second sub-pixel 102 and the third sub-pixel 103 , and do not include the first sub-pixel 101 .

[0100] In some embodiments of the present application, when the acquired position information of the target pixel unit 11 indicates 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 a second brightness of the specific sub-pixel in the target pixel unit 11 includes:
