[0022] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] The embodiments of the present application provide a pixel structure, a full-color reflective display panel and a display device to solve the problem that the existing pixel structure has a large color resistance coverage area, resulting in a low product design aperture ratio and poor reflectivity.

[0024] The pixel structure provided in the embodiment of the present application can be applied to a full-color reflective display panel, and the full-color reflective display panel display device is used to manufacture a display device. The display device is specifically a reflective display screen without backlight. Exemplarily, the non-backlight emissive display screen can be: a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a navigator, or any other product or component with a display function.

[0025] The pixel structure provided in the embodiment of the present application can be applied to a full-color reflective display panel. Exemplarily, the full-color reflective display panel also includes a substrate and a pixel driving circuit arranged on the substrate. The pixel driving circuit can drive each sub-pixel to work and emit light of a corresponding color.

[0026] In order to explain the structure more clearly, the pixel structure will be introduced below with reference to the accompanying drawings.

[0027] For example, see Figure 1 and Figure 2 , Figure 1 Schematic diagram of pixel structure of related technology. Figure 2 A first structural schematic diagram of a pixel structure provided in an embodiment of the present application. The pixel structure comprises: a plurality of pixel units, each of the pixel units comprises at least one sub-pixel 110, and a color resist layer 120 (the color resist layer is an RGB color resist layer) disposed on the sub-pixel 110 and fully covering the sub-pixel 110, the color resist layer 120 comprises a first color resist region 121, a second color resist region 122, and a third color resist region 123 which are sequentially separated and disposed, the first color resist region 121, the second color resist region 122, and the third color resist region 123 are respectively divided into at least two sub-color resist regions (124, 125), and a spacing region (1261, 1262) is formed between adjacent sub-color resist regions (124, 125). By dividing the first color resist region 121, the second color resist region 122 and the third color resist region 123 in the color resist layer 120 into at least two sub-color resist regions (124, 125), and forming a spacing region (1261, 1262) between adjacent sub-color resist regions (124, 125), the aperture ratio of the pixel is increased, the reflectivity of the pixel and the balance of the color gamut can be improved, and the display effect of the product is improved.

[0028] In order to more clearly illustrate the pixel structure provided by the present application, the structure of the color resist layer 120 is described below in conjunction with the accompanying drawings.

[0029] For example, please continue to refer to Figure 2, multiple pixel units are arranged in a matrix. The number of each pixel unit arranged in a matrix can be set according to actual needs and is not limited here. Each pixel unit may include at least one sub-pixel 110 and a color resist layer 120 covering the sub-pixel 110. The color resist layer 120 can be specifically divided into a first color resist area 121, a second color resist area 122, and a third color resist area 123, wherein the first color resist area 121 is specifically a red color resist area, the second color resist area 122 is a green color resist area, and the third color resist area 123 is a blue color resist area. In the present application, the color resist layer 120 uses a color resist material with low penetration and high color gamut. When light enters the color resist layer 120, the color resist layer 120 does not reflect light or reflects very little light. Since the area of ​​the first color filter area 121, the second color filter area 122 and the third color filter area 123 is relatively large, the aperture ratio of the entire sub-pixel 110 is relatively low. In order to increase the aperture ratio of the sub-pixel 110, the present application further divides the first color filter area 121, the second color filter area 122 and the third color filter area 123 into at least two sub-color filter areas (124, 125). A spacing area (1261, 1262) is fixedly reserved between the two sub-color filter areas (124, 125). In this way, the penetration can be increased through these spacing areas (1261, 1262), thereby improving the reflectivity of the product. In addition, the spacing areas (1261, 1262) divide the first color filter area 121, the second color filter area 122 and the third color filter area 123 into a plurality of sub-color filter areas (124, 125), so that the color gamut of each color filter area is more uniform, which can improve the display effect of the entire product.

[0030] Exemplarily, the sub-color filter region (124, 125) includes n first sub-color filter regions 124 divided by the first color filter region 121, the second color filter region 122 and the third color filter region 123 along the width direction of the sub-pixel 110, and / or.

[0031] The first color filter region 121 , the second color filter region 122 , and the third color filter region 123 are each divided into m second sub-color filter areas 125 along the long side direction of the sub-pixel 110 , wherein m and n are both positive integers greater than or equal to 2.

[0032] The long side direction and the wide side direction of the sub-pixel 110 are two directions perpendicular to each other. In practical applications, the long side and the wide side can be the same. In this case, the long side direction of the sub-pixel 110 can be replaced by the first direction, and the wide side direction can be replaced by the second direction, and the first direction is perpendicular to the second direction. Considering the width and length of the first color filter area 121, the second color filter area 122, and the third color filter area 123, in practical applications, the width of the first color filter area 121, the second color filter area 122, and the third color filter area 123 can be divided into a plurality of first sub-color filter areas 124 along the wide side direction of the sub-pixel 110; the length of the first color filter area 121, the second color filter area 122, and the third color filter area 123 can also be divided into a plurality of second sub-color filter areas 125 along the long side direction of the sub-pixel 110. Of course, in practical applications, most designs are: the widths of the first color filter area 121, the second color filter area 122, and the third color filter area 123 are divided into a plurality of first sub-color filter areas 124 along the wide side direction of the sub-pixel 110, and the lengths of the first color filter area 121, the second color filter area 122, and the third color filter area 123 are divided into a plurality of second sub-color filter areas 125 along the long side direction of the sub-pixel 110, so that the aperture ratio and reflectivity of the sub-pixel 110 are further improved, and the uniformity of the product color gamut can be improved. Figure 2 In the embodiment, the first sub-color filter regions 124 are arranged in a horizontal direction, and the second sub-color filter regions 125 are arranged in a column direction. The specific number of the first sub-color filter regions 124 and the second sub-color filter regions 125 can be the same or different, and the specific number can be designed according to actual needs.

[0033] Exemplarily, the areas of the sub-color filter regions (124, 125) in the first color filter region 121, the second color filter region 122, and the third color filter region 123 are the same. The areas of the sub-color filter regions (124, 125) are the same, the color gamut is well balanced, and the display effect can be improved.

[0034] Exemplarily, when the sub-color filter regions (124, 125) include n first sub-color filter regions 124 and m second sub-color filter regions 125, the spacing regions (1261, 1262) include first blank regions 1261 formed in adjacent first sub-color filter regions 124, and second blank regions 1262 formed in adjacent second sub-color filter regions 125. The areas of the first blank regions 1261 are the same, which can improve the uniformity of reflection of the sub-pixel 110 in the first sub-color filter region 124, and the areas of the second blank regions 1262 are the same, which can improve the uniformity of reflection of the sub-pixel 110 in the second sub-color filter region 125.

[0035] Exemplarily, the intervals between the first blank area 1261 and the second blank area 1262 are the same, which can improve the uniformity of the overall reflection of the sub-pixel 110 .

[0036] For example, see Figure 1 and Figure 3 , Figure 1 Schematic diagram of pixel structure of related technology. Figure 3 A second structural schematic diagram of a pixel structure provided in an embodiment of the present application. The pixel structure includes a plurality of pixel units, each pixel unit includes at least one sub-pixel 110, and a color resist layer 120 and a black matrix layer 130 (BM, Black Matrix) disposed on the sub-pixel 110 and fully covering the sub-pixel 110, the color resist layer 120 includes a first color resist region 121, a second color resist region 122, and a third color resist region 123 that are sequentially separated and disposed, the first color resist region 121, the second color resist region 122, and the third color resist region 123 are respectively divided into at least two sub-color resist regions (124, 125), and a spacing region (1261, 1262) is formed between adjacent sub-color resist regions (124, 125); a wiring region is formed around the sub-pixel 110, a portion of the black matrix layer 130 covers the wiring region, and another portion of the color resist layer 120 covers the spacing region (1261, 1262).

[0037] This embodiment is a second structure of the pixel structure. Compared with the second structure of the pixel structure, the second structure of the pixel structure covers the pixel together through the color filter layer 120 and the black matrix layer 130. Specifically, a wiring area is formed at the periphery of the sub-pixel 110, a portion of the black matrix layer 130 covers the wiring area, and another portion of the color filter layer 120 covers the spacing area (1261, 1262). The specific structure of the sub-color filter area (124, 125) in the first color filter area 121, the second color filter area 122 and the third color filter area 123 of the second structure of the pixel structure is the same as the specific structure of the sub-color filter area (124, 125) in the first structure, and will not be repeated here.

[0038] Exemplarily, the sub-color filter region (124, 125) includes n first sub-color filter regions 124 divided by the first color filter region 121, the second color filter region 122 and the third color filter region 123 along the width direction of the sub-pixel 110; and / or.

[0039] The first color filter area 121, the second color filter area 122, and the third color filter area 123 are each divided into m second sub-color filter areas 125 along the long side direction of the sub-pixel 110, wherein m and n are both positive integers greater than or equal to 2. Exemplarily, the areas of each sub-color filter area (124, 125) in the first color filter area 121, the second color filter area 122, and the third color filter area 123 are the same. The specific structures of the first sub-color filter area 124 and the second sub-color filter area 125 in the first color filter area 121, the second color filter area 122, and the third color filter area 123 of the second structure of the pixel structure are the same as those in the first structure, and are not repeated here.

[0040] Exemplarily, when the sub-color filter regions (124, 125) include n first sub-color filter regions 124 and m second sub-color filter regions 125, the spacing regions (1261, 1262) include first blank regions 1261 formed in adjacent first sub-color filter regions 124, and second blank regions 1262 formed in adjacent second sub-color filter regions 125. The specific structures of the first blank regions 1261 and the second blank regions 1262 of the second structure of the pixel structure are the same as those in the first structure, and are not described in detail herein.

[0041] It should be noted that the first structure of the pixel structure of the present application and the second structure of the pixel structure do not have the BM black matrix layer 130. Both can increase the aperture ratio of the sub-pixel 110 and enhance the transmittance through the setting of individual spacing areas, thereby increasing the reflectivity and color gamut balance of the product and improving the display effect of the pixel.
