It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0045] In some related technologies, functional components such as the front camera and IR hole are arranged under the screen of a full-screen mobile phone. The inventor has found through research that due to the insufficient light transmittance of the screen in the related technology, it will affect the light signal reception of the functional components under the screen to a certain extent.

[0046] In view of this, the embodiments of the present disclosure provide a pixel arrangement structure, a display panel and a display device, which can improve the light signal reception of the under-screen functional unit.

[0047] Figure 1 It is a structural schematic diagram of an embodiment of a display device according to the present disclosure.

[0048] refer to Figure 1 In some embodiments, the display device includes a display panel 3 and a functional element 4. The display panel 3 includes a specific pixel arrangement structure, which includes a first pixel region L and a second pixel region H adjacent to each other. The mutual adjacency between the first pixel region L and the second pixel region H means that the distance between the edge of the first pixel region L adjacent to the second pixel region H and the second pixel region H is less than the height of the sub-pixels in the first pixel region L in the column direction. Figure 1 In the embodiment, most of the display panel 3 is the second pixel region H, and the first pixel region L is located at the upper edge of the second pixel region H.

[0049] The functional element 4 may be located on the opposite side of the light emitting side of the display panel 3 , and the light receiving surface of the functional element 4 corresponds to the first pixel area L in the pixel arrangement structure of the display panel 3 , and is used to receive incident light from the light emitting side of the display panel 3 .

[0050] The functional element 4 may include a camera element, such as a front camera of a mobile phone. The functional element may also include an IR element, a reflective sensing element or an ambient light sensor. The first pixel area L and the second pixel area H can display an image, and the functional element can also receive incident light from the outside of the display panel through the first pixel area of ​​the display panel 3.

[0051] In order to increase the light transmittance of the first pixel region L, the pixel density of the first pixel region L can be made lower than the pixel density of the second pixel region H. Therefore, according to the embodiment of the present disclosure, by making the adjacent first pixel region and the second pixel region respectively include pixel groups with different arrangements, and making the pixel density of the first pixel region lower than the pixel density of the second pixel region, on the one hand, the light emitting area of ​​the first pixel region can be reduced, the light transmittance can be increased, so that the functional element receives more light signals; on the other hand, the backplane circuit design of the first pixel region can be simplified.

[0052] Figure 2 Schematic diagram of pixel arrangement according to an embodiment of the pixel arrangement structure disclosed herein.

[0053] refer to Figure 2 In some embodiments, the first pixel region L includes a plurality of repeated first-type pixel groups 10. Each first-type pixel group 10 is arranged in a first arrangement. The first arrangement may be a Real arrangement (i.e., Real RGB). This arrangement may include a plurality of red (R) sub-pixels, green (G) sub-pixels, and blue (B) sub-pixels arranged in an array, and the sub-pixels of three different colors are crossed to form a shape similar to a "chevron". The second pixel region H includes a plurality of repeated second-type pixel groups. Each second-type pixel group is arranged in a second arrangement. The second arrangement may be a Pentile arrangement, that is, a sub-pixel is added on the basis of RGB to achieve, for example, red, green, blue, green (RGBG), red, green, blue, and white (RGBW), red, green, blue, and yellow (RGBY), etc., and some of the sub-pixels in the Pentile arrangement are "shared", thereby achieving a higher resolution than the actual resolution in visual effect.

[0054] The first type of pixel group 10 adopts the Real arrangement, which can minimize the visual effect loss of the first pixel area L. Since the pixel density of the first pixel area L is lower than the pixel density of the second pixel area H, compared with the use of virtual resolution, the first pixel area L of the pixel group adopts the Real arrangement with real resolution can improve the visual experience of the human eye. In addition, the number of sub-pixels of the two colors R and B in the Real arrangement is twice that of the Pentile arrangement. Therefore, under the same aperture ratio (i.e., the same brightness), the brightness of each sub-pixel of the pixel group with the Real arrangement is 1 / 2 of each sub-pixel of the pixel group with the Pentile arrangement, and the corresponding required sub-pixel current is also 1 / 2 of that of the Pentile arrangement, thereby reducing the life decay rate of the sub-pixel.

[0055] exist Figure 2 , the first pixel area L is adjacent to the second pixel area H. The number of sub-pixels in the first pixel area L based on the Real arrangement in both the row and column directions is reduced by 1 / 2 compared with the number of sub-pixels in the second pixel area H based on the Pentile arrangement, so that the pixel density of the first pixel area L can be 1 / 2 of the pixel density of the second pixel area H. In other embodiments, the ratio of the pixel density of the first pixel area L to the pixel density of the second pixel area H can be 1 / N, where N is an integer greater than 1. Here, the pixel density of the first pixel area L is the actual pixel density, and the actual pixel refers to the physical pixel, that is, the smallest physical unit on the display panel that can control the display. The pixel density of the second pixel area H is the virtual pixel density. Virtual pixels are also called intuitive pixels, and their colors are mixed by multiple adjacent color pixels. The bright spots formed by virtual pixels are scattered and located between each actual sub-pixel.

[0056] refer to Figure 2 In some embodiments, the first type of pixel group 10 includes a first sub-pixel 11 of a first color, a second sub-pixel 12 of a second color, and a third sub-pixel 13 of a third color (different colors are distinguished by different filling patterns in the figure). The center lines of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may form a triangle. Figure 2 In the embodiment, the first sub-pixel 11 in the first type pixel group 10 is located on the side of the second sub-pixel 12 and the third sub-pixel 13 away from the second pixel region H (i.e. Figure 2 The upper side of the second sub-pixel 12 and the third sub-pixel 13).

[0057] In some embodiments, the first color is green, the second color is red, and the third color is blue to form the RGB primary colors. In other embodiments, the first color is green, the second color is blue, and the third color is red. In other embodiments, the three colors can also be other colors, such as cyan, magenta, and yellow, to form the CMY primary colors.

[0058] A plurality of repeated first-type pixel groups 10 are arranged in an array. The centers of the first sub-pixels 11 of each column of the first-type pixel group in the first pixel region L are located in the same straight line. For the embodiment in which the first color is green, the human eye is more sensitive to green sub-pixels, so when the green sub-pixels are arranged in a straight line in the column direction, the pixel arrangement in the first pixel region L can be visually more uniform. In addition, the centers of the first sub-pixels 11 of each row of the first-type pixel group 10 can be located in the same straight line, and the centers of the second sub-pixels and the third sub-pixels of each row of the first-type pixel group 10 can be located in the same straight line. By arranging the first sub-pixels in the row direction in a straight line, and the second sub-pixels and the third sub-pixels in a straight line, the white dots formed by the first-type pixel group 10 can be more evenly distributed, thereby improving the display quality.

[0059] exist Figure 2 In the embodiment, the centers of the second sub-pixels 12 in each column of the first type pixel group 10 in the first pixel region L are located on the same straight line, and the centers of the third sub-pixels 13 are located on the same straight line. In this way, the second color and the third color in the first pixel region L can form vertical lines with good consistency in the column direction, and the first sub-pixels of the first color are also arranged in a straight line in the column direction, so that the pixel arrangement in the first pixel region L in the column direction and the row direction is more uniform visually, thereby improving the display quality.

[0060] refer to Figure 2 In some embodiments, the second type of pixel group 20 includes a fourth sub-pixel 21 of a first color, a fifth sub-pixel 22 of a second color, a sixth sub-pixel 23 of a third color, and a seventh sub-pixel 24 of the first color. The first color, the second color, and the third color here can refer to the colors of the sub-pixels in the first pixel region L. For example, the first color is green, the second color is red, and the third color is blue.

[0061] Figure 3 and Figure 4 Schematic diagrams of pixel arrangement of odd-numbered rows and even-numbered rows of pixel groups located in the second display area according to an embodiment of the pixel arrangement structure disclosed herein.

[0062] refer to Figure 3 and Figure 4 , Figure 2The second pixel group 20 in the embodiment can be divided into a first pixel group 20a and a second pixel group 20b according to the arrangement of sub-pixels. A plurality of repeated second pixel groups 20 can be arranged in an array. The first pixel group 20a and the second pixel group 20b are repeated in the row direction and arranged at intervals in the column direction.

[0063] exist Figure 3 In the first pixel group 20a, the fourth sub-pixel 21 is located on the left side of the sixth sub-pixel 23, the fifth sub-pixel 22 is located on the right side of the sixth sub-pixel 23, and the seventh sub-pixel 24 is located at the lower side between the fifth sub-pixel 22 and the sixth sub-pixel 23. Figure 4 In the embodiment, the seventh sub-pixel 24 of the second pixel group 20b is located at the lower left side of the fifth sub-pixel 22, the fourth sub-pixel 21 is located at the right side of the fifth sub-pixel 22, and the sixth sub-pixel 23 is located at the right side of the fourth sub-pixel 21. In the first pixel group 20a and the second pixel group 20b, the fourth sub-pixel 21 and the seventh sub-pixel 24 are both of the first color.

[0064] refer to Figure 2 In some embodiments, the center of the first sub-pixel 11 of each column of the first type pixel group 10 in the first pixel region L and the center of one of the fourth sub-pixel 21 and the seventh sub-pixel 24 of each column of the second type pixel group 20 in the second pixel region H are located in the same straight line. For the embodiment where the first color is green, the human eye is more sensitive to green sub-pixels, so when the green sub-pixels are arranged in a straight line in the column direction of the first pixel region L and the second pixel region H, the white lines in the adjacent first pixel region L and the second pixel region H in the column direction can be more consistent, so that the image change and offset of the first pixel region L and the second pixel region H are relatively small, thereby improving the image quality.

[0065] Figure 5-Figure 8 They are schematic diagrams of pixel arrangement according to some embodiments of the pixel arrangement structure disclosed herein.

[0066] refer to Figure 2 and Figure 5 , Figure 5 Example and Figure 2 Compared with the embodiment, the difference is that the first sub-pixel 11 in the first type pixel group 10 in the first pixel region L is located on the side of the second sub-pixel 12 and the third sub-pixel 13 adjacent to the second pixel region H (ie Figure 5In this way, the sub-pixels of the first pixel region L adjacent to the second pixel region H are the second sub-pixel 12 and the third sub-pixel 13, and the sub-pixels of the second pixel region H adjacent to the first pixel region L are the first sub-pixel 11, so that the colors of the sub-pixels adjacent to each other in the first pixel region L and the second pixel region H are different, reducing or eliminating the risk of color deviation caused by the accumulation of the colors of the second sub-pixel and the third sub-pixel at the boundary between the two pixel regions, thereby improving the picture quality.

[0067] refer to Figure 2 and Figure 6 , Figure 6 Example and Figure 2 Compared with the embodiment, the difference is that the arrangement of the first type pixel groups in the odd and even rows in the first pixel area L is different. Figure 6 In the embodiment, the positions of the second sub-pixels 12 and the third sub-pixels 13 in the first pixel group 10a of the odd rows and the first pixel group 10b of the even rows are opposite to the first sub-pixel 11. The first pixel group 10a of the odd rows and the first pixel group 10b of the even rows are arranged alternately along the column direction. This pixel structure can form the second sub-pixels 12 of the second color and the third sub-pixels of the third color in the first pixel region L in the column direction in an alternating manner, which can reduce the risk of color deviation accumulated by a single color, thereby improving the picture quality.

[0068] In addition, refer to Figure 6 In some embodiments, the center of the second sub-pixel 12 of each column of the first type pixel group 10a or 10b in at least some rows in the first pixel region L and the center of the fifth sub-pixel 22 of the second type pixel group 20 in the corresponding column in the second pixel region H are located in the same straight line. In this way, the first pixel region L and the second pixel region H can form a line of the second color with a relatively consistent shape. Similarly, the center of the third sub-pixel 13 of each column of the first type pixel group 10a or 10b in at least some rows in the first pixel region L and the center of the sixth sub-pixel 23 of the second type pixel group 20 in the corresponding column in the second pixel region H can be located in the same straight line. In this way, the image change and offset of the first pixel region L and the second pixel region H can be relatively small, thereby improving the image quality.

[0069] exist Figure 6 In the embodiment, the colors of the adjacent sub-pixels in the first pixel region L and the second pixel region H are different, which can effectively reduce or eliminate the risk of color deviation caused by the accumulation of sub-pixels with the same color at the boundary of the two pixel regions, thereby improving the picture quality.

[0070] refer to Figure 5 and Figure 7 , Figure 7 Example and Figure 5Compared with the embodiment, the difference is that the arrangement of the first type pixel groups in the odd and even rows in the first pixel area L is different. Figure 7 In the embodiment, the positions of the second sub-pixels 12 and the third sub-pixels 13 in the first pixel group 10a of the odd rows and the first pixel group 10b of the even rows are opposite to the first sub-pixel 11. The first pixel group 10a of the odd rows and the first pixel group 10b of the even rows are arranged alternately along the column direction. This pixel structure can form the second sub-pixels 12 of the second color and the third sub-pixels of the third color in the first pixel region L in the column direction in an alternating manner, which can reduce the risk of color deviation accumulated by a single color, thereby improving the picture quality.

[0071] In addition, refer to Figure 7 In some embodiments, the center of the second sub-pixel 12 of each column of the first type pixel group 10a or 10b in at least some rows in the first pixel region L and the center of the fifth sub-pixel 22 of the second type pixel group 20 in the corresponding column in the second pixel region H are located in the same straight line. In this way, the first pixel region L and the second pixel region H can form a line of the second color with a relatively consistent shape. Similarly, the center of the third sub-pixel 13 of each column of the first type pixel group 10a or 10b in at least some rows in the first pixel region L and the center of the sixth sub-pixel 23 of the second type pixel group 20 in the corresponding column in the second pixel region H can be located in the same straight line. In this way, the image change and offset of the first pixel region L and the second pixel region H can be relatively small, thereby improving the image quality.

[0072] exist Figure 7 In the embodiment, the colors of the adjacent sub-pixels in the first pixel region L and the second pixel region H are different, which can effectively reduce or eliminate the risk of color deviation caused by the accumulation of sub-pixels with the same color at the boundary of the two pixel regions, thereby improving the picture quality.

[0073] Compared with the above embodiments, Figure 8 In some embodiments, a plurality of eighth sub-pixels 25 of the first color may be provided at a position where the second pixel region H is adjacent to the first pixel region L. The eighth sub-pixel 25 is located between the second sub-pixel and the third sub-pixel between each two adjacent columns of the first type of sub-pixel group in the first pixel region. Figure 8 In the figure, at the junction of the first pixel area L and the second pixel area H, sub-pixels of the second color and the third color appear alternately. By adding the eighth sub-pixel 25 to mix the sub-pixels of the second color and the third color, the risk of purple overflow at the junction can be eliminated, thereby improving image quality.

[0074] The eighth sub-pixel 25 can also be added to other embodiments, for example Figure 2 and Figure 6In an embodiment, the eighth sub-pixel 25 may be disposed at a position where the second pixel region H is adjacent to the first pixel region L, and located between the second sub-pixel and the third sub-pixel between every two adjacent columns of the first type of sub-pixel groups in the first pixel region.

[0075] refer to Figure 2-Figure 8 In some embodiments, the second sub-pixel 12, the third sub-pixel 13, the fifth sub-pixel 22 and the sixth sub-pixel 23 have the same shape, which is a hexagon. The first sub-pixel 11 is a hexagon, which has the same shape as the second sub-pixel 12 and the third sub-pixel 13, but is different from the fourth sub-pixel 21 or the seventh sub-pixel 22. The fourth sub-pixel 21 and the seventh sub-pixel 24 are pentagons in opposite directions, and the areas of the two are equal. The areas of the fifth sub-pixel 22 and the sixth sub-pixel 23 are equal, and the area of ​​the fourth sub-pixel 21 is smaller than that of the fifth sub-pixel 22.

[0076] In the above-mentioned embodiments of the pixel arrangement structure of the present disclosure, the shape and arrangement of the sub-pixels in each pixel group are not limited to Figure 2-Figure 8 As shown, other shapes and arrangements may also be used.

[0084] Figure 12-Figure 15 They are schematic diagrams of pixel arrangement according to other embodiments of the pixel arrangement structure disclosed herein.

[0085] refer to Fig. 9 , Figure 12-Figure 15In some embodiments, a plurality of repeated first-type pixel groups 10' are arranged in an array. The centers of the first sub-pixels 11' of each column of the first-type pixel group 10' in the first pixel region L are located in the same straight line. For embodiments in which the first color is green, the human eye is more sensitive to green sub-pixels, so when the green sub-pixels are arranged in a straight line in the column direction, the pixel arrangement in the first pixel region L can be visually more uniform. In addition, the centers of the first sub-pixels 11' of each row of the first-type pixel group 10' can be located in the same straight line, and the centers of the second sub-pixels 12' and the third sub-pixels 13' can be located in the same straight line. By arranging the first sub-pixels 11' in the row direction in a straight line, and the second sub-pixels 12' and the third sub-pixels 13' are also arranged in a straight line, the white point distribution formed by the first-type pixel group 10' can be made more uniform, thereby improving the display quality.

[0086] exist Fig. 9 and Fig.12 In the embodiment, the centers of the second sub-pixels 12' in each column of the first type pixel group 10' in the first pixel region L are located on the same straight line, and the centers of the third sub-pixels 13' are located on the same straight line. In this way, the second color and the third color in the first pixel region L can form vertical lines with good consistency in the column direction, and the first sub-pixels 11' of the first color are also arranged in a straight line in the column direction, so that the pixel arrangement in the first pixel region L in the column direction and the row direction is more uniform visually, thereby improving the display quality.

[0087] exist Fig. 9 , Figure 12-Figure 15 , the first sub-pixel 11' of each column of the first type pixel group 10' in the first pixel region L and the center of one of the fourth sub-pixel 21' and the seventh sub-pixel 24' of each column of the second type pixel group 20' in the second pixel region H are located in the same straight line. For the embodiment where the first color is green, the human eye is more sensitive to green sub-pixels, so when the green sub-pixels are arranged in a straight line in the column direction of the first pixel region L and the second pixel region H, the white lines in the adjacent first pixel region L and the second pixel region H in the column direction can be more consistent, so that the image change and offset of the first pixel region L and the second pixel region H are relatively small, thereby improving the image quality.

[0088] refer to Fig. 9 and Fig.13In some embodiments, the sub-pixels of the first pixel region L adjacent to the second pixel region H are the second sub-pixel 12' and the third sub-pixel 13', and the sub-pixels of the second pixel region H adjacent to the first pixel region L are the third sub-pixel 13' and the second sub-pixel 12', so that the colors of the sub-pixels adjacent to the first pixel region L and the second pixel region H are different, reducing or eliminating the risk of color deviation caused by color accumulation at the junction of the two pixel regions, thereby improving the picture quality.

[0089] and Fig. 9 and Fig.13 Compared with the embodiment, Fig.12 and Fig.14 The first sub-pixel 11' in the first type pixel group 10' in the first pixel region L in the embodiment is located on the side of the second sub-pixel 12' and the third sub-pixel 13' close to the second pixel region H (ie Fig.12 In this way, the sub-pixels of the first pixel region L adjacent to the second pixel region H are the first sub-pixel 11', and the sub-pixels of the second pixel region H adjacent to the first pixel region L are the second sub-pixel 12' and the third sub-pixel 13', so that the colors of the sub-pixels adjacent to each other in the first pixel region L and the second pixel region H are different, reducing or eliminating the risk of color deviation caused by color accumulation at the boundary between the two pixel regions, and can also synthesize white light to avoid purple overflow, thereby improving the picture quality.

[0090] refer to Fig. 9 , Figure 12-14 , Fig.13 and Fig.14 Example and Fig. 9 and Fig.12 Compared with the embodiment, the difference is that the arrangement of the first type pixel groups in the odd and even rows in the first pixel area L is different. Fig.13 and Fig.14 In the embodiment, the positions of the second sub-pixel 12' and the third sub-pixel 13' in the first pixel group 10a' of the odd-numbered rows and the first pixel group 10b' of the even-numbered rows are opposite to the first sub-pixel 11'. The first pixel group 10a' of the odd-numbered rows and the first pixel group 10b' of the even-numbered rows are arranged alternately along the column direction. This pixel structure can make the first pixel region L form the second sub-pixel 12' of the second color and the third sub-pixel 13' of the third color in the column direction in an alternating manner, which can reduce the risk of color deviation accumulated by a single color, thereby improving the picture quality.

[0091] In addition, refer to Fig. 9 , Figure 12-14In some embodiments, the center of the second sub-pixel 12' of each column of the first type pixel group 10', 10a' or 10b' in at least some rows in the first pixel region L and the center of the fifth sub-pixel 22' in the corresponding column of the second type pixel group 20' in the second pixel region H are located in the same straight line. In this way, the first pixel region L and the second pixel region H can form a line of the second color with a relatively consistent shape. Similarly, the center of the third sub-pixel 13' of each column of the first type pixel group 10', 10a' or 10b' in at least some rows in the first pixel region L and the center of the sixth sub-pixel 23' in the corresponding column of the second type pixel group 20' in the second pixel region H can be located in the same straight line. In this way, the image change and offset of the first pixel region L and the second pixel region H can be relatively small, thereby improving the image quality.

[0092] and Fig. 9 , Figure 12-14 Compared with the embodiments shown in the reference Fig.15 In some embodiments, a plurality of eighth sub-pixels 25' of the first color may be provided at a position where the second pixel region H is adjacent to the first pixel region L. The eighth sub-pixel 25 is located between the second sub-pixel 12' and the third sub-pixel 13' between every two adjacent columns of the first type of sub-pixel group 10' in the first pixel region. Fig.15 In the example, at the junction of the first pixel region L and the second pixel region H, sub-pixels of the second color and the third color appear alternately. By adding the eighth sub-pixel 25' to mix the sub-pixels of the second color and the third color, the risk of purple overflow at the junction can be eliminated, thereby improving image quality.

[0093] The eighth sub-pixel 25' can also be added to other embodiments, for example Fig. 9 and Fig.13 In an embodiment, the eighth sub-pixel 25 ′ may be disposed at a position where the second pixel region H is adjacent to the first pixel region L and between the second sub-pixel 12 ′ and the third sub-pixel 13 ′ between every two adjacent columns of the first type of sub-pixel groups in the first pixel region.

[0094] exist Figure 9-Figure 15 In the embodiments shown, the shapes of the sub-pixels in the first type pixel group 10' and the second type pixel group 20' are the same, for example, they are all square. The fourth sub-pixel 21', the fifth sub-pixel 22', the sixth sub-pixel 23' and the seventh sub-pixel 24' in the second type pixel group 20' are all equal in area.

The difference is that Figure 16-Figure 20 In the illustrated embodiment, the first type of pixel group 10 in the first pixel region L is arranged more sparsely, and its pixel density is 1 / 4 of the pixel density of the second pixel region H.
