The display area is non-rectangular, and we can refer to this display area as an irregular display area, and we can refer to the edge that is not a straight line among the edges of the display area, or the edge that forms an angle of 90 degrees with other edges as an irregular edge of the display area, and we can refer to the display panel having this irregular display area as an irregular display panel.

Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
The embodiment of the invention provides a special-shaped display panel, which comprises a display area, wherein the edge of the display area is provided with a plurality of special-shaped sub-pixels, and other positions except the edge of the display area are provided with a plurality of conventional sub-pixels, wherein the shape of each conventional sub-pixel is different from that of each special-shaped sub-pixel, and the light emitting area of each conventional sub-pixel is the same as that of each special-shaped sub-pixel. In order to make the structure and shape of the display area easily apparent to the reader, the following is exemplified:
in one implementation scenario, for example, as shown in fig. 2, fig. 2 is a top view of a portion of a display region in a special-shaped display panel, in fig. 2, a plurality of special-shaped sub-pixels 201 are disposed at the edge of the display region, a plurality of regular sub-pixels 202 are disposed at positions other than the edge of the display region, and the display region is further disposed with a black matrix 203, wherein the shape of each regular sub-pixel 202 is different from the shape of each special-shaped sub-pixel 201, and the light emitting area of each regular sub-pixel 202 is the same as that of each special-shaped sub-pixel 201. The regular sub-pixel 202 may be a sub-pixel having a rectangular shape. The irregular shaped sub-pixel 201 may be a sub-pixel having a non-rectangular shape. Wherein the area of each of the odd-shaped sub-pixels 201 disposed in the display area shown in fig. 2 is the same as that of each of the regular sub-pixels 202. It should be noted that the display area edge mentioned here can be the irregular edge 204 of the display area.
In another implementation scenario, for example, as shown in fig. 3, fig. 3 is a top view of a portion of a display region in a specially-shaped display panel, in fig. 3, a plurality of specially-shaped sub-pixels 301 are disposed at an edge of the display region, a plurality of regular sub-pixels 302 are disposed at positions other than the edge of the display region, and a black matrix 309 is further disposed in the display region, wherein a shape of each regular sub-pixel 302 is different from a shape of each specially-shaped sub-pixel 301, and a light emitting area of each regular sub-pixel 302 is the same as that of each specially-shaped sub-pixel 301. Wherein, the regular sub-pixel 302 may be rectangular in shape. The shaped sub-pixel 301 may be non-rectangular in shape. Each irregular sub-pixel 301 comprises a light-transmitting region 303 and a light-blocking region 304, and the light-emitting area of each irregular sub-pixel 301 refers to the area of the light-transmitting region 303. It should be noted that the display area edge mentioned here may be a special-shaped edge 305 of the display area.
In the embodiment of the invention, the light emitting area of each sub-pixel is the same, so that the color of the light emitted by each pixel is the same under the same light emitting condition, and color cast cannot be generated, and the problem that the color cast of the pixel at the special-shaped edge of the display area of the special-shaped display panel in the prior art can be generated when the pixel emits light is solved.
Optionally, the area of each regular sub-pixel is smaller than the area of each irregular sub-pixel.
For example, as shown in fig. 3, each of the irregular sub-pixels 301 in fig. 3 includes a light-transmitting region 303 and a light-blocking region 304, the area of the light-transmitting region 303, i.e., the light-emitting area, of each of the irregular sub-pixels 301 is the same as the area of each of the regular sub-pixels 302, and the area of each of the irregular sub-pixels 301 is larger than the area of each of the regular sub-pixels 302.
The area of each special-shaped sub-pixel is designed to be larger than that of each conventional sub-pixel, and each special-shaped sub-pixel can be partially shielded, so that the light emitting area of each conventional sub-pixel is the same as that of each special-shaped sub-pixel, and the problem that pixels at the special-shaped edge of a display area in a special-shaped display panel can generate color cast when emitting light is solved.
Optionally, the shape formed by the edge of the plurality of special-shaped sub-pixels close to one side of the edge of the display area is the same as the shape of the edge of the display area. It should be noted that the display area edge mentioned herein may be a special-shaped edge of the display area.
For example, as shown in fig. 3, the irregular edge 305 of the display area is an arc, each regular sub-pixel 302 is rectangular, each irregular sub-pixel 301 has four sides, one side is an arc, three sides are straight lines, the lengths of the three straight lines are different, the length of the shortest straight line in the three straight lines is equal to the length of the short side of the regular sub-pixel 302, the included angle between the shortest straight line in the three straight lines and the other two straight lines is 90 degrees, and the arc formed by the edge of the plurality of irregular sub-pixels 301 close to the irregular edge 305 side of the display area is the same as the arc of the irregular edge 305 of the display area.
In the prior art, for example, as shown in fig. 4, fig. 4 is a top view of a part of an irregular display area in an irregular display panel in the prior art, and in fig. 4, rectangular sub-pixels 401 are arranged in an array, wherein each three rectangular sub-pixels 401 are a pixel 402. A shielding layer 403 is provided in the panel for shielding light so that a portion of the rectangular sub-pixels 401 cannot emit light. The other area outside the area shielded by the shielding layer 403 is a display area, and the shape of the boundary between the display area and the shielding layer 403 is zigzag, which causes that when the special-shaped display panel emits light, the light emitted from the special-shaped edge 404 of the display area is zigzag, which relatively affects the display effect.
In the embodiment of the invention, the shape formed by the edge of the plurality of special-shaped sub-pixels close to one side of the edge of the display area is the same as the shape of the edge of the display area, and the plurality of special-shaped sub-pixels can be well attached to the edge of the display area, so that the problem that the shape of light emitted by the special-shaped edge of the display area of the special-shaped display panel in the prior art is zigzag is solved.
Optionally, a light-emitting area compensation light-shielding layer is disposed in each special-shaped sub-pixel.
The light-emitting area compensation light-shielding layer may be made of any metal material, such as molybdenum.
For example, as shown in fig. 3, a light-emitting area compensation light-shielding layer is disposed in each of the irregular sub-pixels 301 in fig. 3. The light-emitting area compensates the orthographic projection of the light-shielding layer on the special-shaped display panel, and covers the light-tight area 304.
The light-emitting area compensation light-shielding layer is arranged, so that the light-emitting area of each special-shaped sub-pixel is the same as that of each conventional sub-pixel, and color cast is avoided.
Optionally, the light-emitting area compensation light-shielding layer disposed in each special-shaped sub-pixel is far away from the edge of the display area. Here, the display area edge refers to a special-shaped edge of the display area. The light-emitting area compensation light-shielding layer disposed in each of the special-shaped sub-pixels has an orthographic projection on the display panel away from the edge of the display area, i.e. the non-transparent area is away from the special-shaped edge of the display area, for example, as shown in fig. 3, the non-transparent area 304 in fig. 3 is away from the special-shaped edge 305 of the display area.
The position that the orthographic projection of light-emitting area compensation light-shielding layer on special-shaped display panel is located is darker than other positions, sets up light-emitting area compensation light-shielding layer keeping away from the regional edge of display, alright avoid as far as possible that the regional edge of display compares in the regional other positions of display darker, and influences the display effect at the regional edge of display of special-shaped display panel.
Optionally, a plurality of scanning lines are disposed in the display region, and the light-emitting area compensation light shielding layer and the plurality of scanning lines are disposed on the same layer.
For example, as shown in fig. 5, fig. 5 is an enlarged schematic view of the black-free matrix 309 corresponding to the area of the dashed line frame a in fig. 3. In fig. 5, each of the heteromorphic sub-pixels 301 is provided with a scan line 307, a data line 308, a drain electrode 310, and an active layer 311. As shown in fig. 6, fig. 6 is a cross-sectional view along the direction a-a' in fig. 5, and the array substrate 312 in fig. 6 is provided with a scanning line 307 and a light-emitting area compensation light-shielding layer 306. The scanning line 307 and the light-emitting area compensation light-shielding layer 306 are located in the same layer.
Optionally, a thin film transistor is disposed in each of the special-shaped sub-pixels, the thin film transistor includes an active layer, the active layer includes a channel region, and an orthographic projection of the light-emitting area compensation light shielding layer on the display panel covers the channel region in each of the special-shaped sub-pixels.
In one implementation scenario, for example, as shown in fig. 7, fig. 7 is an enlarged schematic view of the black-free matrix 309 corresponding to the area of the dashed line box a in fig. 3. In fig. 7, each irregular sub-pixel 301 is provided with a light-emitting area compensation light-shielding layer 306, a scanning line 313, a data line 314, a drain 315, and an active layer 316, and a portion in a dashed line frame is a thin film transistor 318. As shown in fig. 8, fig. 8 is a cross-sectional view in the direction B-B' in fig. 7, and in fig. 8, a light exit area compensation light shielding layer 306 is provided on the array substrate 319. The orthographic projection of the light-emitting area compensation light-shielding layer 306 on the display panel covers the channel region 317. In this implementation scenario, the shape of the orthographic projection of the light-emitting area compensation light-shielding layer 306 on the display panel can be seen in fig. 9.
In another implementation scenario, for example, as shown in fig. 10, fig. 10 is a top view of a portion of a display region in a special-shaped display panel, in fig. 10, a black matrix 509 is disposed in the display region, a plurality of special-shaped sub-pixels 501 are disposed at edges of the display region, and a plurality of regular sub-pixels 502 are disposed at positions other than the edges of the display region, wherein a shape of each regular sub-pixel 502 is different from a shape of each special-shaped sub-pixel 501, and a light emitting area of each regular sub-pixel 502 is the same as that of each special-shaped sub-pixel 501. The regular sub-pixel 502 is a sub-pixel having a rectangular shape. The irregular sub-pixel 501 is a sub-pixel having a non-rectangular shape. The area of each regular sub-pixel 502 is smaller than the area of each shaped sub-pixel 501. The shape of the edge of the plurality of irregular shaped sub-pixels 501 near the edge of the display area is the same as the shape of the edge of the display area. Each irregular sub-pixel 501 is provided with a light-emitting area compensation light-shielding layer.
