The present embodiment provides a display panel, wherein the display area 10 is a shaped display area, and the display area 10 includes at least one segment of a shaped edge 101, wherein the shaped edge 101 overlaps with a part of the inner edge of the non-display area 20. The direction of extension of the profiled edge 101 intersects the first direction x and the second direction y, respectively. In this embodiment, only the special-shaped edge 101 is taken as an example of a segment of an oblique line. Optionally, the special-shaped edge 101 may be a section of curve; alternatively, the shaped edge 101 may alternatively be a broken line. Moreover, the display area 10 may include two or more sections of irregular edges, which is not limited in this embodiment.
The display area 10 comprises a shaped edge area 121 and the shaped edge area 121 comprises a shaped edge 101. In other words, the outer boundary of the shaped edge region 121 comprises the shaped edge 101.
The display area 10 includes a plurality of pixels 40, and the plurality of pixels 40 may display an image. For example, the multi-pixel 40 may display multiple luminances, and/or multiple colors to display an image.
Referring to fig. 3, optionally, the pixel 40 includes a light shielding region 401 and a light transmitting region 402, wherein the pixel 40 includes light-opaque structures such as traces and electronic elements, which need to be shielded to avoid affecting the display effect. The light blocking area 401 includes light-opaque structures of the pixels 40, such as traces, electronic components, and the like. Alternatively, the light blocking regions 401 of two adjacent pixels 40 may be connected; alternatively, the light blocking regions 401 of the plurality of pixels 40 in the display region 10 may be connected as a whole. Light exits the light transmissive region 402, and the light transmissive region 402 is an area of the pixel 40 effective for performing a display function.

Alternatively, the shape of the shaped edge pixel 42 is different from the shape of the regular pixel 41. Optionally, the shape of the plurality of shaped edge pixels 42 is not identical to accommodate the shaped edge 101, which improves the jagging of the display area 10 at the shaped edge 101 compared to the prior art.
The area of a single shaped-edge pixel 42 is larger than the area of a single conventional pixel 41 and the shaped edge area 121 comprises at least two shaped-edge pixel rows 420, the shaped-edge pixel rows 420 comprising a plurality of shaped-edge pixels 42. The area of the pixel 40 may include an area of the light blocking region 401 and an area of the light transmitting region 402. In this embodiment, the area of a single special-shaped edge pixel 42 is larger, and compared to the prior art, the edge pixel with the too small area adjacent to the special-shaped edge in the prior art can be eliminated to set at least two special-shaped edge pixel rows 420 in the present invention, and the special-shaped edge pixels 42 in the at least two special-shaped edge pixel rows 420 can "share" the area of the edge pixel with the too small area adjacent to the special-shaped edge in the prior art, so that the area of a single special-shaped edge pixel is larger than that of a single conventional pixel.
In this embodiment, the at least two shaped edge pixel rows 420 include a first shaped edge pixel row 4201 and a second shaped edge pixel row 4202. The first shaped edge pixel row 4201 is adjacent to the shaped edge 101 and the second shaped edge pixel row 4202 is disposed on a side of the first shaped edge pixel row 4201 remote from the shaped edge, the second shaped edge pixel row 4202 can be configured as a transition row. The shape of the shaped edge pixel 42 in the second shaped edge pixel row 4202 is more similar to the shape of the conventional pixel 41 with respect to the shaped edge pixel 42 in the first shaped edge pixel row 4201. Optionally, the area of the light-transmissive region 402 of the shaped-edge pixel 42 in the second shaped-edge pixel row 4202 is closer to the area of the light-transmissive region 402 of the conventional pixel 41. In this embodiment, by setting at least two special-shaped edge pixel rows 420, the special-shaped edge pixels 42 in the special-shaped edge region 121 can gradually transit to the conventional pixels 41, and the difference between the display effects of the special-shaped edge region 121 and the display effects of the remaining display regions is reduced, so that the display image is finer and smoother, and the display quality is improved.
In addition, the area of the light-transmitting region 402 of the normal pixel 41 is S1, and the area of the light-transmitting region 402 of any one of the special-shaped edge pixels 42 is S2, wherein 80% by S1 is equal to or less than S2 is equal to or less than 120% by S1. In this embodiment, the difference between the area of the transparent region 402 of the shaped edge pixel 42 and the area of the transparent region 402 of the regular pixel 41 is small, so that the phenomenon that the edge of the display region 10 is dark at the shaped edge 101 can be improved.
Alternatively, with continued reference to fig. 1, fig. 2 and fig. 3, the light shielding region 401 of the pixel 40 is covered by the black matrix in the direction perpendicular to the plane of the display panel. It should be noted that fig. 3 is a view obtained by observing the display panel in a direction perpendicular to the plane of the display panel. The display panel may include a Black Matrix (Black Matrix) having functions of preventing a light leakage phenomenon of the display panel, increasing a color contrast of the display panel, and the like. In this embodiment, the light shielding region 401 is covered by the black matrix, and the black matrix is used to shield the wiring, the electronic element, and other structures in the light shielding region 401, so as to prevent the wiring, the electronic element, and other structures in the light shielding region 401 from reflecting light and leaking light, thereby improving the display quality. It is understood that the area of the light blocking region 401 of the pixel may be adjusted by adjusting the coverage area of the black matrix. For example, the area of the black matrix may be adjusted by adjusting the width of the black matrix along the first direction x or adjusting the width of the black matrix along the second direction y, so that the coverage area of the black matrix may be adjusted, thereby realizing the area adjustment of the light blocking region 401 of the pixel.
Optionally, please continue to refer to fig. 4, where fig. 4 follows the reference numerals of fig. 2, and the same parts are not repeated. In this embodiment, the shaped edge region 121 includes a first shaped edge pixel row 4201, the first shaped edge pixel row 4201 being adjacent to the shaped edge 101, wherein in the first shaped edge pixel row 4201, the shape of the edge of the light-transmissive region 401 of each shaped edge pixel 42 near the shaped edge 101 is the same as the shape of the shaped edge 101. In the present embodiment, only the special-shaped edge 101 is taken as an example of a segment that is inclined. In particular, the first shaped edge pixel row 4201 is adjacent to the shaped edge 101, i.e., no other pixels exist between the first shaped edge pixel row 4201 and the shaped edge 101. In the first shaped-edge pixel row 4201, the edge of the light-transmitting region 401 of the shaped-edge pixel 42 near the shaped edge 101 is a light-transmitting region first edge 42-1, the shape of the light-transmitting region first edge 42-1 is the same as that of the shaped edge 101, and is a straight line segment, and optionally, the extending direction of the light-transmitting region first edge 42-1 is the same as that of the shaped edge 101. In other alternative implementations, when the shaped edge 101 is a curve, the shape of the shaped edge pixel 42 near the edge of the light-transmitting region 401 of the shaped edge 101 is a curve. Alternatively, when the shaped edge 101 is a broken line, the shape of the shaped edge pixel 42 near the edge of the light-transmissive region 401 of the shaped edge 101 is correspondingly a broken line. In the present embodiment, in the first special-shaped edge pixel row 4201, by setting the edge shape of the light-transmitting region 401 of each special-shaped edge pixel 42 close to the special-shaped edge 101 to be the same as the shape of the special-shaped edge 101, when the display panel performs a display function, in the first special-shaped edge pixel row 4201, the boundary of the image displayed by each special-shaped edge pixel 42 is the same as the shape of the special-shaped edge 101 on the side close to the special-shaped edge 101, and when the special-shaped edge 101 is a segment of a diagonal line or a segment of a curved line, compared to the prior art, the jagging phenomenon of the display region 10 at the special-shaped edge 101 can be improved, thereby improving the display quality.
It should be noted that, in fig. 4, the light shielding region 401 is not provided with a filling pattern, and is only illustrated by a line frame, in order to clearly illustrate the technical solution of the present embodiment.
In some alternative embodiments, referring to fig. 5, the pixel 40 includes at least a first color sub-pixel 40a, a second color sub-pixel 40b and a third color sub-pixel 40 c; for both the regular and the shaped edge pixels, the ratio of the areas of the light-transmitting regions 402 of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c is the same, and is X: y: and Z. In this embodiment, the pixel 40 includes at least three sub-pixels with different colors, for example, the pixel 40 includes a red sub-pixel, a blue sub-pixel, and a green sub-pixel; or the pixel 40 includes a red sub-pixel, a blue sub-pixel, a green sub-pixel, and a white sub-pixel. The present embodiment does not specifically limit the color of the sub-pixels of the pixel 40. The pixel 40 includes at least three sub-pixels of different colors, and can display a colorful picture. In the pixel 40, three sub-pixels of different colors can be mixed to display three or more colors.
For the regular pixel 41, the ratio of the areas of the light-transmitting regions 402 of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c is X: y: z; in the shaped-edge pixel 42 located in the shaped-edge region 121, the ratio of the areas of the light-transmitting regions 402 of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c is also X: y: z, so that the color obtained by mixing the sub-pixels with three different colors in the regular pixel 41 is the same as the color obtained by mixing the sub-pixels with three different colors in the irregular edge pixel 42, the color of the color mixture of the irregular edge pixel 42 can be prevented from being different from that of the regular pixel 41, and the phenomenon of color shift or uneven color balance of the display area 10 at the irregular edge 101 can be prevented.
Optionally, X: y: and Z is 1: 1: 1, that is, the areas of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c are the same, and optionally, when the first color sub-pixel 40a is a red sub-pixel, the second color sub-pixel 40b is a green sub-pixel, and the third color sub-pixel 40c is a blue sub-pixel, the color mixture of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c can obtain white light with better white balance, thereby improving the display quality.
Optionally, referring to fig. 6, in the special-shaped edge region 121, the light shielding regions 401 of at least two special-shaped edge pixels 42 are different in area. In fig. 6, for clearly illustrating the technical solution of the present embodiment, the area size of the light blocking region 401 is illustrated only by a circular pattern, and the larger the number of circular patterns is, the larger the area of the light blocking region 401 is. In fig. 6, the special-shaped edge pixel 42 includes a special-shaped edge pixel 42a and a special-shaped edge pixel 42b, wherein the light blocking areas 401 of the special-shaped edge pixel 42a and the special-shaped edge pixel 42b have different areas, and the area of the light transmitting area 402 in the special-shaped edge pixel 42 is adjusted by setting the size of the area of the light blocking area 401 of the special-shaped edge pixel 42, so that the area ratios of the light transmitting areas 402 of the first color sub-pixel 40a, the second color sub-pixel 40b, and the third color sub-pixel 40c are X: y: z, preventing the display area 10 from color shift or color balance unevenness at the shaped edge 101.
In some alternative embodiments, please refer to fig. 7, and fig. 7 follows the reference numerals of fig. 6, and the description of the same parts is omitted. In the present embodiment, the extending direction of the gate line in the shaped edge region 121 intersects the first direction x, and the shape of the shaped edge pixel 42 is different from that of the regular pixel 41. Specifically, the irregular edge area 121 includes a gate line 31a, a gate line 31b, and a gate line 31c, and the extending directions of the gate line 31a, the gate line 31b, and the gate line 31c all intersect the first direction x. Accordingly, the shape of the shaped-edge pixel 42 is adaptively adjusted corresponding to the shapes of the gate line 31a, the gate line 31b, and the gate line 31c, and the shape of the shaped-edge pixel 42 is different from that of the conventional pixel 41. In the display panel provided by the embodiment, the extending direction of the gate line in the special-shaped edge region 121 and the shape of the special-shaped edge pixel 42 are adjusted to adjust the area of the special-shaped edge pixel 42, so that the area of a single special-shaped edge pixel 42 is larger than that of a single conventional pixel 41, the area of the light-transmitting region in the special-shaped edge pixel 42 is further increased, and the phenomenon that the edge of the display region 10 is darker at the special-shaped edge 101 is improved.
Optionally, with continued reference to fig. 7, at least one section of the special-shaped edge includes a first line 1011, and an acute included angle θ between a straight line of the first line 1011 and the first direction x1. In this embodiment, the special-shaped edge of the display area 10 includes an inclined line segment, which is the first line segment 1011.
Optionally, with continuing reference to fig. 7, in the special-shaped edge region 121, the gate line 31 extends along a straight line, and an acute included angle with the first direction x is smaller than or equal to θ1(ii) a For different gate lines 31 in the shaped edge region 121, along the direction away from the shaped edge 101, the acute angle included angle between the extending direction of the gate line 31 and the first direction x gradually decreases, and the acute angle included angle between the extending direction of the gate line 31 and the straight line of the first line 1011 gradually increases. In this embodiment, the irregular edge area 121 includes the gate line 31a, the gate line 31b and the gate line 31 c. An acute included angle between any one of the gate lines 31a, 31b and 31c and the first direction x is less than or equal to θ1. Specifically, the gate line 31a forms an acute angle θ with the first direction x1aThe gate line 31b has an acute angle θ with the first direction x1bThe gate line 31c has an acute angle θ with the first direction x1c. Wherein, theta1c＜θ1b＜θ1a。
Also, in the present embodiment, for different gate lines 31 in the shaped edge region 121, the extending direction of the plurality of gate lines 31 tends to the first direction x along the direction away from the shaped edge 101. Specifically, along the direction away from the special-shaped edge 101, the acute angle included angle between the extending direction of the gate line 31 and the first direction x gradually decreases, and the acute angle included angle between the extending direction of the gate line and the straight line of the first line 1011 gradually increases. In other words, the extending directions of the gate lines 31a, 31b and 31c gradually tend to the first direction x, and the gate lines 31 in the shaped edge region 121 and the gate lines 31 in the rest of the display regions can be prevented from sudden changes in the extending directions by gradual transition of the extending directions of the gate lines 31a, 31b and 31c, so as to reduce the difference of the display effects of the shaped edge region 121 and the rest of the display regions. Accordingly, the shape of the shaped edge pixel 42 may gradually trend toward the shape of the regular pixel 41 in a direction away from the shaped edge, so that the difference in display effect of the shaped edge region 121 and the remaining display region may be further reduced. Optionally, in the direction away from the special-shaped edge 101, the area of the light-transmitting area of the special-shaped edge pixel 42 is gradually decreased, so that the light-emitting amount of the special-shaped edge pixel 42 is gradually decreased, the light-emitting amount of the special-shaped edge pixel 42 in the special-shaped edge 121 is gradually transited to the conventional pixel 41, and the display effect difference caused by the large area difference between the light-transmitting areas of the special-shaped edge pixel 42 and the conventional pixel 41 is avoided.
Optionally, referring to fig. 8, the reference numerals in fig. 6 are used in fig. 8, and the same parts are not repeated in this embodiment, at least one section of the special-shaped edge includes a first arc 1012, and the curvature of the first arc 1012 is α1. In this embodiment, the shaped edge of the display area 10 may include a curved segment, which is the first arc 1012.
Optionally, with continued reference to fig. 8, in the shaped edge region 121, the gate line 31 extends along an arc, and the curvature of the gate line 31 is less than or equal to α1(ii) a For different gate lines in the shaped edge region 121, the curvature of the gate line 31 gradually decreases in a direction away from the shaped edge 101. In this embodiment, the irregular edge region 121 includes a gate line 31d, a gate line 31e and a gate line 31fFor example, the curvature of any one of the gate line 31d, the gate line 31e, and the gate line 31f is α or less1。
Also, in the present embodiment, for different gate lines 31 in the shaped edge region 121, the extending direction of the plurality of gate lines 31 tends to the first direction x along the direction away from the shaped edge 101. Specifically, the curvature of the gate line 31 gradually decreases in a direction away from the shaped edge 101. In other words, the extending directions of the gate lines 31d, 31e and 31f gradually tend to the first direction x, and the gate lines 31 in the shaped edge region 121 and the gate lines 31 in the rest of the display regions can be prevented from sudden changes in the extending directions by gradual transition of the extending directions of the gate lines 31d, 31e and 31f, so as to reduce the difference of the display effects of the shaped edge region 121 and the rest of the display regions. Accordingly, the shape of the shaped edge pixel 42 may gradually trend toward the shape of the regular pixel 41 in a direction away from the shaped edge, so that the difference in display effect of the shaped edge region 121 and the remaining display region may be further reduced. Optionally, in the direction away from the special-shaped edge 101, the area of the light-transmitting area of the special-shaped edge pixel 42 is gradually decreased, so that the light-emitting amount of the special-shaped edge pixel 42 is gradually decreased, the light-emitting amount of the special-shaped edge pixel 42 in the special-shaped edge 121 is gradually transited to the conventional pixel 41, and the display effect difference caused by the large area difference between the light-transmitting areas of the special-shaped edge pixel 42 and the conventional pixel 41 is avoided.
Optionally, please refer to fig. 9, where fig. 9 follows the reference numerals of fig. 2, and the same parts are not repeated. In this embodiment, the display area 10 includes a section of the shaped edge 101, and the shaped edge 101 is a section of a curve, and the section of the curve is concave toward one side of the display area 10. For the shaped edge pixel 42 in the same shaped edge pixel column 422, the area of the light-transmitting region 402 of the shaped edge pixel 42 gradually decreases in a direction away from the shaped edge 101. Wherein the shaped edge pixels 42 in the same column along the second direction y are shaped edge pixel columns 422. In fig. 9, the size of the area of the light-transmitting region 402 is illustrated only in a square pattern, and the smaller the number of square patterns, the smaller the area of the light-transmitting region 402. It should be noted that, in different shaped-edge pixels 42, the number of square patterns only represents the size of the area of the light-transmitting region 402, and does not represent the proportional relationship of the area of the light-transmitting region 402. In this embodiment, along the direction away from the irregular edge, the area of the light-transmitting area 402 of the irregular edge pixel 42 is gradually decreased, so that the light-emitting amount of the irregular edge pixel 42 is gradually decreased, the light-emitting amount of the irregular edge pixel 42 in the irregular edge area 121 is gradually transited to the conventional pixel 41, and the display effect difference caused by the large area difference between the irregular edge pixel 42 and the conventional pixel 41 in the light-transmitting area 402 is avoided.
Optionally, please continue to refer to fig. 9, 100% S1 ≦ S2 ≦ S1. That is, the area of the light-transmitting region 402 of the normal pixel 41 is S1, the area of the light-transmitting region 402 of the shaped-edge pixel 42 is S2, and the area of the light-transmitting region 402 of the shaped-edge pixel 42 is greater than or equal to the area of the light-transmitting region 402 of the normal pixel 41. Optionally, in the direction away from the special-shaped edge 101, the area of the light-transmitting region 402 of the special-shaped edge pixel 42 is gradually reduced, so that the light emitting amount of the special-shaped edge pixel 42 is gradually close to the normal pixel 41, and the display effect of the special-shaped edge region 121 is gradually transited to the remaining display regions, thereby further reducing the difference between the display effects of the special-shaped edge region 121 and the remaining display regions. Optionally, on the basis of the display panel provided in fig. 9, in the same irregular edge pixel row 422, along the direction away from the irregular edge 101, the areas of the light-transmitting regions 402 of the irregular edge pixels 42 form an equal-difference row, so as to further make the display effect of the irregular edge region 121 gradually transition to the rest of the display regions more uniformly.
