Detailed Description

The present disclosure will now be described more specifically with reference to the following examples. It should be noted that the following description of some embodiments is provided herein for purposes of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.

Fig. 1 is a schematic structural diagram of a special-shaped display panel in the related art. As shown in fig. 1, the irregular display panel includes: a display area 2 having an irregular edge portion and a light shielding area 1 located around the display area 2, a pixel array composed of a plurality of pixels is disposed in the display area 2, wherein the pixel array is divided into edge pixels 3 located at the outermost side and constituting the irregular edge portion and a center pixel 3' located at the center. For example, the irregular edge of the irregular display panel includes an arc shape, a bevel edge, a dog-leg shape, and the like.

The conventional pixel shape is designed to be rectangular, and when the irregular edge of the irregular display panel is formed, the edge pixels 3 having the same size need to be arranged in a ladder shape. When displaying, the edge pixel 3 and the light-shielding region 1 have a certain brightness difference, so that the edge of the display panel may exhibit a zigzag arrangement.

Especially, when a plurality of edge pixels 3 are located in the same row or the same column, the pixels of the row/column and the pixels of the adjacent row/column are obviously protruded to present a stair shape, that is, the edge of the display panel is jagged, thereby reducing the visual effect of the edge of the display panel and seriously affecting the user experience.

To solve or alleviate the above-mentioned problems, the present disclosure provides a display substrate. Fig. 2 is a schematic structural diagram of a display substrate according to an embodiment of the disclosure. As shown in fig. 2, the display substrate includes: a display area 2 having irregular edge portions and a light-shielding area 1, a pixel array including edge pixels 3 located at the outermost sides and constituting the irregular edge portions and a center pixel 3' located at the center being disposed in the display area 2. Each edge pixel 3 includes at least one edge sub-pixel 4, each edge sub-pixel 4 includes a light-shielding sub-region 401 and a light-emitting sub-region 402 arranged in the row direction, and the light-shielding sub-region 401 is located on a side of each edge sub-pixel 4 close to the light-shielding region 1.

The edge pixels 3 specifically include a pixel in contact with the irregular edge, and at least one pixel, for example, one pixel, two pixels, or three pixels, located on one side of the plurality of pixels in contact with the irregular edge and arranged continuously along the arrangement direction and away from the light-shielding region 1. In an exemplary embodiment, as shown in fig. 2, one pixel is included extending along the arrangement direction of the plurality of edge pixels 3 and a side facing away from the light-shielding region 1.

The "light-shielding sub-region 401" refers to a region through which light cannot pass in the region corresponding to the edge sub-pixel 4. In some exemplary embodiments, the light-shielding sub-region 401 may be made opaque by disposing a light-shielding sub-pattern at the light-shielding sub-region 401. The "light-exiting sub-region 402" refers to a region through which light is transmitted in a region corresponding to the edge sub-pixel 4.

In the present disclosure, the light-shielding sub-region 401 is provided in each edge sub-pixel 4 on the side close to the light-shielding region 1 in the row direction, so that a plurality of edge pixels 3 adjacent to the irregular edge can have a gradually changing aperture ratio along the irregular edge, and the jaggy feeling can be weakened.

In some embodiments, the irregular edge portion includes: at least one protruding area, wherein the protruding area comprises a plurality of edge pixels 3 which are positioned in the same row or the same column and are continuously arranged; the protruding area is provided with a corresponding aperture ratio gradual change direction, and the aperture ratio of a plurality of edge pixels 3 in the protruding area is gradually increased along the corresponding aperture ratio gradual change direction, so that the sawtooth feeling can be weakened; the aperture ratio gradual change direction is a direction away from the light shielding region 1 in the arrangement direction of the plurality of edge pixels 3 in the protruding region.

The aperture ratio of one edge pixel 3 is equal to the ratio of the area of the light-emitting sub-region 402 of all the edge sub-pixels 4 included therein to the sum of the areas of the light-emitting sub-region 402 and the light-shielding sub-region 401 of all the edge sub-pixels 4 included therein.

Fig. 3 is a schematic structural diagram of an edge pixel in fig. 2. As shown in fig. 3, the edge pixel 3 includes 3 edge sub-pixels 4a, 4b and 4c, the 3 edge sub-pixels 4a, 4b and 4c respectively have corresponding light-shielding sub-regions 401 and light-emitting sub-regions 402, and assuming that the areas of the light-shielding regions 1 of the 3 edge sub-pixels 4 are S1, S2 and S3, respectively, and the areas of the light-emitting sub-regions 402 of the 3 edge sub-pixels 4 are S1 ', S2 ' and S3 ', respectively, the aperture ratio Q of the edge pixel 3 is equal to:

in the above embodiment, each edge pixel 3 includes 3 edge sub-pixels 4a, 4b and 4c, and the case where the edge sub-pixels 4a, 4b and 4c are all rectangular is only for exemplary purposes, and does not limit the technical solution of the present disclosure. In the present disclosure, the number of edge sub-pixels included in each edge pixel 3 and the shape of each edge sub-pixel are not limited.

In some embodiments, each edge pixel 3 includes a plurality of edge sub-pixels 4 with different colors, and the area ratios of the light-shielding sub-region 401 and the light-emitting sub-region 402 of the edge sub-pixels 4 located in the same edge pixel 3 are equal or approximately equal, so that the problem of color cast of the edge pixel 3 can be effectively avoided. In some embodiments, each of the edge pixels 3 may include a red edge sub-pixel, a blue edge sub-pixel, and a green edge sub-pixel. Of course, other color sub-pixels such as a white edge sub-pixel and/or a yellow edge sub-pixel may be included according to design requirements.

In some embodiments, the shape and size of the light-shielding sub-region 401 of each edge sub-pixel 4 located in the same edge pixel 3 are the same or approximately the same; the light-emitting sub-regions 402 of the edge sub-pixels 4 within the same edge pixel 3 are the same or approximately the same shape and size. At this time, different edge sub-pixels 4 within the same edge pixel 3 can be prepared based on the same mask.

In order to better understand the technical solution of the present disclosure, the following description will be made with reference to examples.

Fig. 4 is a schematic diagram of a plurality of edge pixels arranged in a row and arranged in series to form a protruding region in the related art. As shown in fig. 4, a plurality of edge pixels 3 arranged in a row and in a row in series will form a relatively large-sized projecting step B (i.e., a projecting region a), and the projecting step B is large in size, so that a jaggy feeling is easily generated.

Fig. 5 is a schematic view of a modified version of the protruding region of fig. 4 according to the present disclosure. As shown in fig. 5, by arranging the light-shielding sub-region 401 at a side closer to the light-shielding region 1 in the row direction within the edge sub-pixel 4 (the left side within the edge sub-pixel 4 in the case shown in fig. 5), and the aperture ratio of the plurality of edge pixels 3 within the protrusion region a gradually increases in the corresponding aperture ratio gradation direction (the horizontal right side in the case shown in fig. 5), the visual brightness of the edge pixel 3 within the protrusion region a closest to the corner C of the protruding step can be made to decrease, and the visual brightness of the edge pixel 3 within the protrusion region a and in the corresponding aperture ratio gradation direction gradually increases, that is, corresponding to the irregular edge portion, there is a smooth change in the visual brightness of the user, and thus the jaggy feeling can be weakened or even completely eliminated.

With reference to fig. 5, the protrusion area a includes 4 edge pixels 3, which are a first edge pixel 3a, a second edge pixel 3b, a third edge pixel 3c, and a fourth edge pixel 3d from left to right, respectively, and the edge sub-pixels 4 included in the 4

edge pixels

3a, 3b, 3c, and 3d are a first edge sub-pixel, a second edge sub-pixel, a third edge sub-pixel, and a fourth edge sub-pixel, respectively. That is, for the convex region a, the visual brightness corresponding to the first edge pixel 3a, the second edge pixel 3b, the third edge pixel 3c, and the fourth edge pixel 3d sequentially increases, so that the jaggy feeling can be weakened or even completely eliminated.

In some embodiments, the plurality of edge pixels 3 located in the same protrusion area gradually decrease in size of the light-shielding sub-area 401 included therein along the corresponding aperture ratio gradually-changing direction. Taking the case shown in fig. 5 as an example, in the convex region a, the sizes of the light-shielding sub-patterns in the first edge sub-pixel, the second edge sub-pixel, the third edge sub-pixel and the fourth edge sub-pixel gradually decrease.

In some embodiments, in the convex region, the difference between the aperture ratios of two adjacent edge pixels 3 in the corresponding aperture ratio gradual change direction is a fixed value. Taking the case shown in fig. 5 as an example, the "two adjacent edge pixels" at this time specifically mean two edge pixels directly adjacent in the horizontal rightward direction. For example, the first edge pixel 3a and the second edge pixel 3b are two adjacent edge pixels, the second edge pixel 3b and the third edge pixel 3c are two adjacent edge pixels, and the third edge pixel 3c and the fourth edge pixel 3d are two adjacent edge pixels. In the convex region a, the difference between the aperture ratios of the first edge pixel 3a, the second edge pixel 3b, the third edge pixel 3c, and the fourth edge pixel 3d is a fixed value.

In some embodiments, in the convex region, the difference between the aperture ratios of two adjacent edge pixels 3 in the corresponding aperture ratio gradual change direction varies linearly or proportionally. Taking the case shown in fig. 5 as an example, in the convex region a, the differences between the aperture ratios of the first edge pixel 3a, the second edge pixel 3b, the third edge pixel 3c, and the fourth edge pixel 3d are linearly or proportionally changed.

The above-mentioned technical scheme that the difference between the aperture ratios of two adjacent edge pixels 3 in the corresponding aperture ratio gradual change direction in the convex region is set to be a fixed value, and is changed linearly or in an equal ratio can make the visual brightness change of the edge pixels 3 in the edge pixels 3 smoother, which is beneficial to the weakening of the jaggy feeling.

Fig. 6 is a schematic diagram of a plurality of edge pixels in the same column and arranged in series to form a protruding region in the related art. As shown in fig. 6, a plurality of edge pixels 3 arranged in the same column and in series form a relatively large projecting step D (i.e., a projecting region E), and the projecting step D is likely to generate a jaggy feeling due to its large size.

Fig. 7 is a schematic view of a modified version of the raised area of fig. 6 according to the teachings of the present disclosure. As shown in fig. 7, by arranging the light-shielding sub-region 401 at a side closer to the light-shielding region 1 in the row direction within the edge sub-pixel 4 (the right side within the edge sub-pixel 4 in the case shown in fig. 7), and the aperture ratio of the plurality of edge pixels 3 within the protrusion region E gradually increases in the corresponding aperture ratio gradation direction (vertically downward in the case shown in fig. 7), the visual brightness of the edge pixel 3 within the protrusion region E closest to the corner C of the protruding step D can be made to decrease, and the visual brightness of the edge pixel 3 within the protrusion region E and in the corresponding aperture ratio gradation direction can be made to gradually increase, that is, there is a smooth change in the visual brightness of the user corresponding to the irregular edge portion, and thus the jaggy feeling can be weakened or even completely eliminated.

With reference to fig. 7, the protruding region E includes 4 edge pixels 3, which are respectively a fifth edge pixel 3E, a sixth edge pixel 3f, a seventh edge pixel 3g, and an eighth edge pixel 3h from top to bottom, and the edge sub-pixels 4 included in the 4

edge pixels

3E, 3f, 3g, and 3h are respectively a fifth edge sub-pixel, a sixth edge sub-pixel, a seventh edge sub-pixel, and an eighth edge sub-pixel. That is, for the convex region E, the visual brightness corresponding to the fifth edge pixel 3E, the sixth edge pixel 3f, the seventh edge pixel 3g, and the eighth edge pixel 3g sequentially increases, so that the jaggy feeling can be weakened or even completely eliminated.

In some embodiments, the plurality of edge pixels 3 located in the same protrusion area gradually decrease in size of the light-shielding sub-area 401 included therein along the corresponding aperture ratio gradually-changing direction. Taking the case shown in fig. 7 as an example, in the convex region E, the sizes of the light-shielding sub-patterns in the fifth edge sub-pixel, the sixth edge sub-pixel, the seventh edge sub-pixel, and the eighth edge sub-pixel gradually decrease.

In some embodiments, in the convex region, the difference between the aperture ratios of two adjacent edge pixels 3 in the corresponding aperture ratio gradual change direction is a fixed value. Taking the case shown in fig. 7 as an example, the "two adjacent edge pixels" at this time specifically refer to two edge pixels that are directly adjacent in the vertically downward direction. For example, the fifth edge pixel 3e and the sixth edge pixel 3f are two adjacent edge pixels, the sixth edge pixel 3f and the seventh edge pixel 3g are two adjacent edge pixels, and the seventh edge pixel 3g and the eighth edge pixel 3h are two adjacent edge pixels. In the convex area E, the difference in aperture ratio among the fifth edge pixel 3E, the sixth edge pixel 3f, the seventh edge pixel 3g, and the eighth edge pixel 3h is a fixed value.

In some embodiments, in the convex region, the difference between the aperture ratios of two adjacent edge pixels 3 in the corresponding aperture ratio gradual change direction varies linearly or proportionally. Taking the case shown in fig. 7 as an example, in the convex region E, the differences in aperture ratio among the fifth edge pixel 3E, the sixth edge pixel 3f, the seventh edge pixel 3g, and the eighth edge pixel 3h are linearly or proportionally changed.

The light-shielding sub-pattern 6 and the black matrix 5 may be made of the same material. Also, the light-shielding sub-pattern 6 and the black matrix 5 may have the same thickness.
