[0030] The color filter pixel layer of the display module is composed of RGB pixels. In order to display the rounded corners in the corner area, the black border layer on the cover needs to be rounded to cover the corner pixels to form the rounded corners. However, since the RGB pixel area left after the masking cannot reach the same proportion, RGB will mix into different colors, presenting a colorful visual effect instead of the normal display color, which is particularly obvious in a dark environment, thus affecting the display effect of the display module.

[0031] The present disclosure provides a display module. Figure 1 is a front view structural diagram of a display module in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of a cross-sectional structure of a display module in an exemplary embodiment of the present disclosure. Figure 1 , Figure 2 As shown, the display module 1 includes a cover plate 11, a color filter pixel layer 12 and a shielding layer 13. The color filter pixel layer 12 is arranged on one side of the cover plate 11. The color filter pixel layer 12 includes a plurality of pixels 121 distributed in an array. The pixel 121 includes a first sub-pixel 1211, a second sub-pixel 1212 and a third sub-pixel 1213. The first sub-pixel 1211, the second sub-pixel 1212 and the third sub-pixel 1213 are arranged in sequence along a preset direction to form a sub-pixel group. The shielding layer 13 is arranged between the cover plate 11 and the color filter pixel layer 12. The shielding layer 13 includes a main structure 131 and a group of auxiliary structures 132. The main structure 131 covers the corner area 123 of the color filter pixel layer 12, so that the color filter pixel layer 12 forms a main area 122 including an arc corner 124. The auxiliary structure 132 is arranged on the pixel 121 associated with the arc corner 124 in the main area 122, so that the sum of the exposed areas of the first sub-pixel 1211 associated with the same unit segment 1241 of the arc corner 124, the sum of the exposed areas of the second sub-pixel 1212 and the sum of the exposed areas of the third sub-pixel 1213 are the same, wherein the unit segment 1241 coincides with the projection of a sub-pixel group in a direction perpendicular to a preset direction.

[0032] It should be noted that the unit segment 1241 of the arc corner 124 coincides with the projection of a sub-pixel group in a direction perpendicular to the preset direction, that is, the unit segment 1241 represents the portion of the arc corner 124 corresponding to a sub-pixel group in a direction perpendicular to the preset direction. Figure 1 As shown, the arc corner 124 may include two unit sections 1241, and each unit section 1241 corresponds to a sub-pixel group in a direction perpendicular to a preset direction. The preset direction may refer to the horizontal direction, and the direction perpendicular to the preset direction may refer to the vertical direction. Alternatively, the preset direction may also be the horizontal direction, and the direction perpendicular to the preset direction may refer to the horizontal direction.

[0033] The shielding layer 13 is disposed between the cover plate 11 and the color filter pixel layer 12, so that the partial structure of the color filter pixel layer 12 located below the shielding layer 13 can be covered, so that the structure exposed to the shielding layer 13 can form a visual effect through the cover plate 11. For example, the shielding layer 13 can be a black ink layer formed on the inner surface of the cover plate 11 facing the color filter pixel layer 12. Alternatively, the shielding layer 13 can also be a light shielding structural member assembled between the cover plate 11 and the color filter pixel layer 12, and the present disclosure is not limited to this.

[0034] The shielding layer 13 of the display module 1 includes a main structure 131 and a group of auxiliary structures 132. The main structure 131 covers the corner area 123 of the color filter pixel layer 12, so that the color filter pixel layer 12 forms a main area 122 including the arc corner 124. The auxiliary structure 132 is arranged on the pixel 121 associated with the arc corner 124 in the main area 122, so that the sum of the exposed areas of the first sub-pixel 1211 associated with the same unit section 1241 of the arc corner 124, the sum of the exposed areas of the second sub-pixel 1212 and the sum of the exposed areas of the third sub-pixel 1213 are the same. That is, after the arc corner 124 is formed, the proportions of the first sub-pixel 1211, the second sub-pixel 1212 and the third sub-pixel 1213 exposed to the shielding layer 13 and associated with the same unit section 1241 of the arc corner 124 are the same, so the visual effect at the arc corner 124 can be optimized after light mixing.

[0035] In some embodiments, the fitting curve of the center of a group of auxiliary structures 132 and the arc corner 124 are located on a concentric circle to ensure the edge curvature of the arc corner 124 during the display process and avoid deformation of the arc corner 124 during the actual process due to the occlusion of the auxiliary structure 132. Figure 1 As shown in the curve connecting each auxiliary structure 132, the fitting curve of the center of the auxiliary structure 132 may refer to a smooth curve formed by connecting the centers of multiple auxiliary structures 132 in a group of auxiliary structures 132 through arcs. For example, when the auxiliary structure 132 is circular, the fitting curve of the center of the auxiliary structure 132 may be a curve formed by connecting the centers of each auxiliary structure 132 through arcs.

[0036] In the above embodiment, the shape of the auxiliary structure 132 may include at least one of a circle, an ellipse, and a polygon. Among them, when the shape of the auxiliary structure 132 is a circle, it is convenient to form on the inner surface of the cover plate 11, and it is also helpful to calculate the area and center position of the circular auxiliary structure 132. In addition, in a group of auxiliary structures 132, the shapes of each auxiliary structure 132 may be the same or different, and the present disclosure is not limited to this. When the shapes of each auxiliary structure 132 in a group of auxiliary structures 132 are the same, it is possible to simplify the relevant calculation process of obtaining the position and size of the auxiliary structure 132 through the arc corner 124 and the exposed area of ​​the pixel 121 associated with the arc corner 124.

[0037] The size of the auxiliary structure 132 may be associated with the area of ​​the pixel 121 covered by the auxiliary structure 132 that is exposed from the main structure 131. For example, when the auxiliary structure 132 is located above a first sub-pixel 1211 and a second sub-pixel 1212, the area of ​​the first sub-pixel 1211 exposed from the main structure 131 is larger than the area of ​​the second sub-pixel 1212 exposed from the main structure 131, and the size of the auxiliary structure 132 covering the first sub-pixel 1211 may be larger than the size of the auxiliary structure 132 covering the second sub-pixel 1212. Of course, in the actual distribution of the auxiliary structure 132, the proportion of the exposed areas of the first sub-pixel 1211, the second sub-pixel 1212, and the third sub-pixel 1213 associated with the arc-shaped corner 124 should also be referred to.

[0038] In some embodiments, a preset interval may be provided between the auxiliary structure 132 and the arc corner 124 to prevent the auxiliary structure 132 from blocking the arc corner 124 and causing display interference, while facilitating adjustment of a fitting curve of the center of a group of auxiliary structures 132 .

[0039] In some embodiments, the area of ​​each pixel 121 exposed to the auxiliary structure 132 is greater than or equal to 1 / 5 of the area of ​​the pixel 121. When the area of ​​the pixel 121 exposed to the auxiliary structure 132 is too small, the function of the pixel 121 in the color mixing process will be affected. Therefore, making the area of ​​each pixel 121 exposed to the auxiliary structure 132 greater than or equal to 1 / 5 of the area of ​​the pixel 121 can ensure the realization of the function of the pixel 121.

[0040] In the above embodiment, the pixels 121 associated with the curved corner 124 in the main body area 122 include the pixels 121 through which the curved corner 124 passes and / or the pixels 121 adjacent to the curved corner 124 .

[0041] When the pixels 121 associated with the curved corner 124 in the main area 122 only include the pixels 121 through which the curved corner 124 passes, the exposed area of ​​each pixel associated with the curved corner 124 can be the same, so as to improve the overall display effect of the curved corner 124 by making the exposed areas of the first sub-pixel 1211, the second sub-pixel 1212 and the third sub-pixel 1213 of the sub-pixel groups corresponding to different unit segments 1241 the same.

[0042] When the pixels 121 associated with the arc corner 124 in the body area 122 include the pixels 121 through which the arc corner 124 passes and the pixels 121 adjacent to the arc corner 124, for example Figure 1 As shown, label hm is the pixel 121 through which the arc corner 124 passes, label n is the pixel 121 adjacent to the arc corner 124, and an auxiliary structure 132 can be set above labels h, n, and jm for partial shielding so that the fitting curve formed by the center of the auxiliary structure 132 forms a concentric circle with the arc corner 124.

[0043] The pixels labeled hj form a sub-pixel group corresponding to a unit segment 1241 of the arc corner 124, and the pixels 121 associated with the unit segment 1241 include pixels labeled hj and n. The pixels labeled km form a sub-pixel group corresponding to another unit segment 1241 of the arc corner 124, and the pixels 121 associated with the unit segment 1241 include pixels labeled km.

[0044] The types of pixels 121 labeled hj and n and the ratio of the area of ​​the pixels 121 exposed from the main structure 131 to the area of ​​the pixels 121 are respectively: the first sub-pixel 1211, the area accounts for 2 / 3; the second sub-pixel 1212, the area accounts for 1 / 3; the third sub-pixel 1213, the area accounts for 1 / 2; the second sub-pixel 1212, the area accounts for 1. The total areas of the three types of pixels are respectively: the first sub-pixel 1211, the area accounts for 2 / 3; the second sub-pixel 1212, the area accounts for 4 / 3; the third sub-pixel 1213, the area accounts for 1 / 2. By coordinating the size of the auxiliary structure 132, the auxiliary structure 132 can cover the pixel 121 labeled hj, n in the following proportions: 1 / 6, 0, 1 / 6, 5 / 6, so that the sum of the exposed areas of the first sub-pixel 1211 associated with the same unit segment 1241 in the main area 122, the sum of the exposed areas of the second sub-pixel 1212 and the sum of the exposed areas of the third sub-pixel 1213 are all equal to 1 / 2 of the pixel 121 area.

[0045] The pixel types marked km and the proportion of the area of ​​the pixel 121 exposed from the main structure 131 to the area of ​​the pixel 121 are: first sub-pixel 1211, accounting for 2 / 3 of the area; second sub-pixel 1212, accounting for 5 / 6 of the area; third sub-pixel 1213, accounting for 5 / 6 of the area.

[0046] It should be noted that the sum of the exposed areas of the first sub-pixels 1211 associated with the two unit segments 1241 may be the same or different, the sum of the exposed areas of the second sub-pixels 1212 associated with the two unit segments 1241 may be the same or different, and the sum of the exposed areas of the third sub-pixels 1213 associated with the two unit segments 1241 may be the same or different.

[0047] For example, when the sum of the exposed areas of the first sub-pixels 1211 associated with the two unit segments 1241 is the same, by coordinating the size of the auxiliary structure 132, the auxiliary structure 132 can sequentially cover the pixel 121 labeled km with an area ratio of 1 / 6, 1 / 3, and 1 / 3, so that the sum of the exposed areas of the first sub-pixels 1211 associated with the same arc corner 124 in the main area 122, the sum of the exposed areas of the second sub-pixels 1212, and the sum of the exposed areas of the third sub-pixels 1213 are all equal to 1 / 2 of the area of ​​the pixel 121.

[0048] For another example, when the sum of the exposed areas of the first sub-pixels 1211 associated with two unit segments 1241 is different, the auxiliary structure 132 can sequentially cover the pixel 121 labeled km with an area ratio of 1 / 12, 1 / 4, and 1 / 4, so that the sum of the exposed areas of the first sub-pixels 1211 associated with the same arc corner 124 in the main area 122, the sum of the exposed areas of the second sub-pixels 1212, and the sum of the exposed areas of the third sub-pixels 1213 are all equal to 7 / 12 of the area of ​​the pixel 121.

[0049] In some embodiments, the arc corner 124 may pass through the intersection of a pair of pixels 121 disposed diagonally to reduce the number of pixels 121 blocked by the shielding layer 13 and reduce the interference of the arc corner 124 on the surrounding pixels 121 .

[0050] In some embodiments, Figure 3 As shown, the color filter pixel layer 12 may include a rectangular structure, and the main area 122 includes four arc-shaped corners 124 with the same size parameters. During the display process, a rectangular display effect with four rounded corners can be obtained, and the visual effect at each rounded corner is improved.

[0051] The display module 1 may further include a driving layer 15 and a sealant 14 connecting the driving layer 15 and the shielding layer 13, and the color filter pixel layer 12 is disposed in an assembly space 16 surrounded by the driving layer 15, the shielding layer 13, the sealant 14 and the cover plate 11. The driving layer 15 may be TFT glass for driving the liquid crystal display module 1 to realize the display function.

[0052] Among them, the first sub-pixel 1211, the second sub-pixel 1212 and the third sub-pixel 1213 can refer to the RGB pixel 121 in the liquid crystal display module 1, the first sub-pixel 1211 can be the R pixel 121 in the RGB pixel 121, the second sub-pixel 1212 can be the G pixel 121 in the RGB pixel 121, and the third sub-pixel 1213 can be the B pixel 121 in the RGB pixel 121.

[0053] The present disclosure further provides an electronic device, which includes the above-mentioned display module 1.

[0054] Since the shielding layer 13 of the display module 1 includes a main structure 131 and a group of auxiliary structures 132, the main structure 131 covers the corner area 123 of the color filter pixel layer 12, so that the color filter pixel layer 12 forms a main area 122 including an arc corner 124. The auxiliary structure 132 is arranged on the pixel 121 associated with the arc corner 124 in the main area 122, so that the sum of the exposed areas of the first sub-pixel 1211 associated with the same arc corner 124 in the main area 122, the sum of the exposed areas of the second sub-pixel 1212 and the sum of the exposed areas of the third sub-pixel 1213 are the same. That is, after the arc corner 124 is formed, the first sub-pixel 1211, the second sub-pixel 1212 and the third sub-pixel 1213 of the pixel 121 exposed to the shielding layer 13 and associated with the arc corner 124 have the same proportion, so the visual effect at the arc corner 124 can be optimized after light mixing.

[0055] It should be noted that the above-mentioned electronic devices may be mobile phones, tablet computers, laptop computers, medical terminals, vehicle-mounted terminals, wearable devices, etc.

[0056] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
