[0049] Smart surfaces are one of the future development directions of automotive interior and exterior decoration. They can add electronic functions to product structures through certain dielectric materials. Smart surfaces can be hidden when users do not need them, and when users need them, users can activate them through proximity, gestures or voice control to obtain feedback and responses. However, current smart surfaces have the problem of color cast during use.

[0050] For example, the transmittance in the blue wavelength region is often lower than that in the red or green wavelength region. Affected by the smart surface, this often leads to lower luminous efficiency and color reproduction rate, which can cause the image on the smart surface to be yellowish.

[0051] In order to solve the above problems, the embodiments of the present application provide a display panel and a display device, which can improve the color shift problem caused by the different transmittances of sub-pixels of different colors and improve the display effect.

[0052] Reference Figure 1 In one embodiment, a display panel is provided, including a plurality of pixel groups 100 arranged in an array, each pixel group 100 including a first sub-pixel 110, a third sub-pixel 120, a second sub-pixel 130, and a fourth sub-pixel 140 sequentially arranged along a first direction X. In this embodiment, the third sub-pixel 120 and the fourth sub-pixel 140 emit the same color.

[0053] In a plurality of pixel groups 100 arranged in an array, a plurality of first sub-pixels 110 are arranged along a second direction Y intersecting with a first direction X to form a first pixel column Y1, a plurality of second sub-pixels 130 are arranged along a second direction Y intersecting with the first direction X to form a second pixel column Y3, a plurality of third sub-pixels 120 are arranged along a second direction Y intersecting with the first direction X to form a third pixel column Y2, a plurality of fourth sub-pixels 140 are arranged along a second direction Y intersecting with the first direction X to form a fourth pixel column Y4, and the first pixel column Y1, the third pixel column Y2, the second pixel column Y3, and the fourth pixel column Y4 are arranged in sequence along the first direction X. In this embodiment, the first direction X may be perpendicular to the second direction Y, and further, the first direction X may be an X-axis direction, and the second direction Y may be a Y-axis direction.

[0054] For the same pixel group 100, the sum of the number of the third sub-pixels 120 and the fourth sub-pixels 140 is greater than the number of the first sub-pixels 110 and greater than the number of the second sub-pixels 130. That is, the sum of the number of the third sub-pixels 120 and the fourth sub-pixels 140 with the same luminous color is greater than the number of the first sub-pixels 110, and the sum of the number of the third sub-pixels 120 and the fourth sub-pixels 140 with the same luminous color is greater than the number of the second sub-pixels 130. In practical applications, the third sub-pixels 120 and the fourth sub-pixels 140 may be sub-pixels with lower transmittance. In this embodiment, by increasing the total number of the third sub-pixels 120 and the fourth sub-pixels 140 in the same pixel group 100, that is, increasing the total number of sub-pixels with lower transmittance, the area proportion of the sub-pixels with lower transmittance can be increased, thereby preventing the display panel from having a color shift problem.

[0055] In one embodiment, for the same pixel group 100, the sum of the light-emitting areas of the third sub-pixel 120 and the fourth sub-pixel 140 is greater than the light-emitting area of ​​the first sub-pixel 110, and the sum of the light-emitting areas of the third sub-pixel 120 and the fourth sub-pixel 140 is greater than the light-emitting area of ​​the second sub-pixel 130. That is, the sum of the light-emitting areas of the third sub-pixel 120 and the fourth sub-pixel 140 with low transmittance is set to be greater than the light-emitting area of ​​the first sub-pixel 110, and greater than the light-emitting area of ​​the second sub-pixel 130, that is, while increasing the number of sub-pixels with low transmittance, ensure that their light-emitting areas are greater than the light-emitting areas of other sub-pixels, thereby effectively preventing the problem of color shift in the display of the display panel due to the low transmittance of some sub-pixels.

[0056] In practical applications, the transmittance in the blue wavelength region is generally lower than the transmittance in other color (such as red or green) wavelength regions. Therefore, in this embodiment, the third sub-pixel 120 and the fourth sub-pixel 140 can both be set as blue sub-pixels, that is, the number of blue sub-pixels is increased to increase the light-emitting area of ​​the blue sub-pixels, thereby solving the color shift problem caused by the low transmittance of the blue sub-pixels and improving the display effect.

[0057] In this embodiment, the luminous colors of adjacent pixel columns are different, that is, the luminous colors of the first sub-pixel 110 and the third sub-pixel 120 are different, the luminous colors of the third sub-pixel 120 and the second sub-pixel 130 are different, and the luminous colors of the second sub-pixel 130 and the fourth sub-pixel 140 are different. When the luminous colors of the third sub-pixel 120 and the fourth sub-pixel 140 are both blue, the luminous color of the first sub-pixel 110 and the luminous color of the second sub-pixel 130 can be other colors other than blue, thereby avoiding the concentrated appearance of a large area of ​​blue light, resulting in light and dark stripes during display. For example, in a specific example, the first sub-pixel 110 is a red sub-pixel and the second sub-pixel 130 is a green sub-pixel, or the first sub-pixel 110 is a green sub-pixel and the second sub-pixel 130 is a red sub-pixel, which are not listed here one by one.

[0058] Reference Figure 2 In one embodiment, a pixel group 100 is located in a virtual quadrilateral 500, and the virtual quadrilateral 500 has a first side 510 and a second side 520 arranged opposite to each other along the second direction Y. The first sub-pixel 110 and the second sub-pixel 130 both include a first side and a second side arranged opposite to each other in the second direction Y, and the first side of the first sub-pixel 110 and the first side of the second sub-pixel 130 coincide with the first side 510 of the virtual quadrilateral 500, and the second side of the first sub-pixel 110 and the second side of the second sub-pixel 130 coincide with the second side 520 of the virtual quadrilateral 500.

[0059] In one embodiment, the third sub-pixel 120 and the fourth sub-pixel 140 both include a first side and a second side that are relatively arranged in the second direction Y. For the same pixel group 100, the first side of the third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500 and the first side of the fourth sub-pixel 140 close to the first side 510 of the virtual quadrilateral 500 coincide with the first side 510 of the virtual quadrilateral 500, and the second side of the third sub-pixel 120 close to the second side 520 of the virtual quadrilateral 500 and the second side of the fourth sub-pixel 140 close to the second side 520 of the virtual quadrilateral 500 coincide with the second side 520 of the virtual quadrilateral 500.

[0060] In this embodiment, the number of third sub-pixels 120 and the number of fourth sub-pixels 140 may both exceed one. In the above, “the third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500” refers to a third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500 in the third pixel column Y2 of the same pixel group 100. Similarly, “the fourth sub-pixel 140 close to the first side 510 of the virtual quadrilateral 500” refers to a third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500 in the fourth pixel column Y4 of the same pixel group 100. A fourth sub-pixel 140 of the first side 510 of 500, “a third sub-pixel 120 close to the second side 520 of the virtual quadrilateral 500” refers to a third sub-pixel 120 close to the second side 520 of the virtual quadrilateral 500 in the third pixel column Y2 of the same pixel group 100, and “a fourth sub-pixel 140 close to the second side 520 of the virtual quadrilateral 500” refers to a fourth sub-pixel 140 close to the second side 520 of the virtual quadrilateral 500 in the fourth pixel column Y4 of the same pixel group 100. When the number of third sub-pixels 120 is only one, “the third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500” and “the third sub-pixel 120 close to the second side 520 of the virtual quadrilateral 500” refer to the only third sub-pixel 120, and when the number of fourth sub-pixels 140 is only one, “the fourth sub-pixel 140 close to the first side 510 of the virtual quadrilateral 500” and “the fourth sub-pixel 140 close to the second side 520 of the virtual quadrilateral 500” refer to the only fourth sub-pixel 140.

[0061] In one embodiment, the first side of the first sub-pixel 110, the first side of the second sub-pixel 130, the first side of the third sub-pixel 120 close to the first side 510 of the virtual quadrilateral 500, and the first side of the fourth sub-pixel 140 close to the first side 510 of the virtual quadrilateral 500 all overlap with the first side 510 of the virtual quadrilateral 500, and the second side of the first sub-pixel 110, the second side of the second sub-pixel 130, the second side of the third sub-pixel 120 close to the second side 520 of the virtual quadrilateral 500, and the second side of the fourth sub-pixel 140 close to the second side 520 of the virtual quadrilateral 500 all overlap with the second side 520 of the virtual quadrilateral 500.

[0063] In one embodiment, the fourth sub-pixel 140 includes a third side and a fourth side that are oppositely disposed in the first direction X, and the fourth side of the fourth sub-pixel 140 coincides with the fourth side 540 of the virtual quadrilateral 500 .

[0064] In one embodiment, in the same pixel group 100 , the ratio of the sum of the number of the third sub-pixels 120 and the fourth sub-pixels 140 , the number of the first sub-pixels 110 , and the number of the second sub-pixels 130 is 3:1:1 or 4:1:1.

[0065] For example, in the same pixel group 100: the number of the first sub-pixel 110 and the second sub-pixel 130 is 1 each, and the sum of the number of the third sub-pixel 120 and the fourth sub-pixel 140 is 3, wherein the number of the third sub-pixel 120 is 1 and the number of the fourth sub-pixel 140 is 2, or the number of the third sub-pixel 120 is 2 and the number of the fourth sub-pixel 140 is 1; for another example, in the same pixel group 100: the number of the first sub-pixel 110 and the second sub-pixel 130 is 1 each, and the sum of the number of the third sub-pixel 120 and the fourth sub-pixel 140 is 4, wherein the number of the third sub-pixel 120 and the fourth sub-pixel 140 is 2 each.

[0066] In one embodiment, the third sub-pixel 120 and the fourth sub-pixel 140 include a main pixel and a spare pixel, and the spare pixel is configured to light up when the attenuation value of the luminous efficiency of the main pixel reaches a preset value. The main pixel is lit up together with the first sub-pixel 110 and the second sub-pixel 130 in the early stage of display of the display panel, while the spare pixel is not lit up in the early stage of display of the display panel, but is lit up when the attenuation value of the luminous efficiency of the main pixel reaches a preset value, so as to prevent the color shift problem of the display panel in the later stage caused by the short life of the blue light sub-pixel.

[0067] In this embodiment, the luminous efficiency attenuation value of the main pixel can be detected in real time by the driving chip. If the luminous efficiency attenuation value of the main pixel is detected to reach a preset value, the driving chip lights up the spare pixel through the pixel driving circuit corresponding to the spare pixel.

[0068] In one embodiment, the preset value may range from 50% to 95%. For example, the preset value may be 50%, 60%, 70%, 80%, 95%, etc., which may be set according to actual needs and is not specifically limited thereto.
