Curved or circular screens are typically used in smart bracelets or watches, offering smaller sizes and higher resolutions. However, as market demand for larger circular or curved displays continues to rise, medium-to-large-sized displays with lower resolutions are becoming increasingly popular. The edges of circular or curved screens are prone to visually noticeable jagged edges and colored stripes, affecting display quality and user experience. Summary of the Invention

[0094] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0095] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as “connected” or “linked” are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0096] It should be noted that the dimensions and shapes of the figures in the accompanying drawings do not reflect actual proportions and are intended only to illustrate the content of this disclosure. Furthermore, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0097] In related technologies, when the edge of the display area has an arc or circular portion, at least some sub-pixels will be missing in the arc or circular portion, resulting in uneven color mixing in that area. This easily leads to visually visible color stripes, affecting the display effect and user experience. Adjusting the aperture ratio of the sub-pixels corresponding to the arc or circular portion can improve the color stripe effect.

[0098] For example, such as Figure 1 , Figure 2 As shown, the display panel includes a plurality of first pixels 5 and a plurality of second pixels 6; each pixel 4 includes a plurality of sub-pixels 7; each first pixel 5 includes at least one first sub-pixel opening area 8 located within the display area 1 and corresponding to the sub-pixel 7, wherein at least one first sub-pixel opening area 8 in each first pixel 5 is adjacent to the curved portion 3, and the shape of the first sub-pixel opening area 8 at least partially adjacent to the curved portion 3 is non-rectangular; each second pixel 6 is located within the display area 1, and the second pixel 6 includes a second sub-pixel opening area 9 corresponding to the sub-pixel 7, wherein the shape of the second sub-pixel opening area 9 is rectangular; the ratio of the area of ​​each first sub-pixel opening area 8 to the area of ​​the sub-pixel 7 corresponding to the first sub-pixel opening area 8 in the display area 1 is a first aperture ratio, and the ratio of the area of ​​the second sub-pixel opening area 9 to the area of ​​the sub-pixel corresponding to the second sub-pixel opening area 9 is a second aperture ratio, wherein the first aperture ratio is less than the second aperture ratio.

[0099] It should be noted that the display panel includes multiple horizontally and vertically intersecting scan lines and data lines, which divide the sub-pixel areas. When the first pixel includes a non-rectangular first sub-pixel opening area, the area of ​​the sub-pixel corresponding to the non-rectangular first sub-pixel opening area is not entirely located within the display area. That is, the curved section divides the sub-pixel into a first part located within the display area and a second part located outside the display area. For this sub-pixel, the area of ​​the sub-pixel within the display area is the area of ​​the first part. Conversely, for a rectangular first sub-pixel opening area, the area of ​​the corresponding sub-pixel is located within the display area. Therefore, for this sub-pixel, the area of ​​the sub-pixel within the display area is the area of ​​the complete sub-pixel area.

[0100] It should be noted that the subpixel region is roughly rectangular. Specifically, within the subpixel region, when the scan line and signal line are straight lines and perpendicular to each other, the subpixel region is rectangular. When the scan line or signal line is not a straight line, the subpixel region can be regarded as a similar rectangular shape with at least one pair of non-straight sides.

[0101] Without changing the sub-pixel size, this is equivalent to reducing the aperture area of ​​each sub-pixel in the display area of ​​the first pixel, thus reducing the area of ​​the colored stripes. This not only reduces the area of ​​the colored stripes but also lowers the brightness due to the reduced aperture area, significantly improving the severity of the colored stripes. However, because the first aperture ratio of the first pixel adjacent to the curved portion is smaller than the second aperture ratio of the second pixel entirely within the display area, a significant brightness difference exists between the first and second pixels, resulting in a jagged appearance. Furthermore, the greater the difference in aperture ratio between the first and second pixels, the more pronounced the jagged appearance.

[0102] This disclosure provides a display panel, such as... Figure 3 , Figure 4 , Figure 5 As shown, it includes: a display area 1 and at least one non-display area 2 adjacent to the display area 1; the boundary between the at least one non-display area 2 and the display area 1 has a curved portion 3;

[0103] The display panel includes:

[0104] Multiple pixels 4 are arranged in an array along a first direction X and a second direction Y, including: multiple first pixels 5, multiple second pixels 6, and multiple first pixel groups 48; each first pixel group 48 includes at least one third pixel 49; each pixel 4 includes multiple sub-pixels 7; wherein the first direction X and the second direction Y intersect; the first pixel group 48 is located between the first pixels 5 and the second pixels 6; each third pixel 49 includes: a third sub-pixel opening region 50 corresponding to the sub-pixel 7, the shape of the third sub-pixel opening region 50 being rectangular; the area of ​​each first sub-pixel opening region 8 is equal to the area of ​​the first sub-pixel opening region 8. The ratio of the area of ​​sub-pixel 7 corresponding to sub-pixel 8 in display area 1 is less than the ratio of the area of ​​the second sub-pixel opening area 9 to the area of ​​the sub-pixel 7 corresponding to the second sub-pixel opening area 9; the ratio of the area of ​​the third sub-pixel opening area 50 to the area of ​​sub-pixel 7 in the third pixel 49 is not less than the ratio of the area of ​​each first sub-pixel opening area 8 to the area of ​​the sub-pixel 7 corresponding to the first sub-pixel opening area 8 in display area 1; the ratio of the area of ​​the third sub-pixel opening area 50 to the area of ​​sub-pixel 7 in the third pixel 49 is less than the ratio of the area of ​​the second sub-pixel opening area 9 to the area of ​​the sub-pixel 7 corresponding to the second sub-pixel opening area 9.

[0105] It should be noted that the ratio of the area of ​​the third sub-pixel aperture region to the area of ​​the sub-pixels in the third pixel is the third aperture ratio; that is, the third aperture ratio is less than the second aperture ratio, and the third aperture ratio is not less than the first aperture ratio.

[0106] The display panel provided in this embodiment has an opening area near the edge of the display area close to the non-display area that is at least partially non-rectangular in shape, thereby reducing the jaggedness at the boundary between the display area and the non-display area. The first aperture ratio is smaller than the second aperture ratio. Without changing the sub-pixel area, this is equivalent to reducing the opening area of ​​each sub-pixel in the first pixel within the display area, thus reducing the area of ​​the colored stripes. Furthermore, due to the reduced opening area, the sub-pixel brightness decreases, significantly improving the severity of the colored stripes. Moreover, with the first aperture ratio being smaller than the second aperture ratio, the aperture ratio of the sub-pixels in the first pixel group located between the first and second pixels is smaller than the second aperture ratio but not smaller than the first aperture ratio. This allows for a gradual transition in the aperture ratios of the first, third, and second pixels, avoiding large differences in brightness between adjacent pixels caused by excessive differences in aperture ratios. This prevents jaggedness caused by large brightness differences, improving the display effect and enhancing the user experience.

[0107] It should be noted that the subpixel area refers to the area of ​​the subpixel region divided by the scan lines and data lines.

[0108] It should be noted that, Figure 4 , Figure 5 for Figure 3 An enlarged schematic diagram of region A in the diagram. Regions A, B, and C in diagram 3 each include curved sections at different locations.

[0109] It should be noted that when there are no other first sub-pixel opening areas between the first sub-pixel opening area and the curved portion, it is defined that the first sub-pixel opening area is adjacent to the curved portion.

[0110] It should be noted that, Figure 3 , Figure 4 , Figure 5 The example provided illustrates a scenario where the first direction X is perpendicular to the second direction Y, with the first direction being horizontal and the second direction being vertical. In practice, the first direction X and the second direction Y can be interchanged, or the first direction X can be vertical and the second direction Y can be horizontal.

[0111] In some embodiments, such as Figure 4 As shown, multiple sub-pixels 7 in each pixel 4 are arranged along the first direction X.

[0112] In some embodiments, such as Figure 4 As shown, each pixel 4 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B.

[0113] It should be noted that in specific implementations, when the boundary between the display area and the non-display area includes a curved section, such as... Figure 4 As shown, the non-display area 2 covers part of sub-pixel 7; as Figure 4 , Figure 5 As shown, some pixels 4 corresponding to curve 3 do not contain the complete three-pixel opening area in display area 1; that is, the sub-pixels in some pixels are completely located in the non-display area. Sub-pixels completely located in the non-display area do not participate in the display.

[0114] In some embodiments, such as Figure 4 As shown, the width of sub-pixel 7 in the first direction X is smaller than its width in the second direction Y.

[0115] In some embodiments, such as Figure 4 As shown, the area of ​​each sub-pixel 7 is equal.

[0116] In some embodiments, such as Figure 5 As shown, in the second pixel 6, the area of ​​the opening region 9 of each second sub-pixel is equal.

[0117] In some embodiments, such as Figure 3 As shown, the curved portion 3 includes at least one circular arc.

[0118] In some embodiments, such as Figure 4 As shown, the colors of two adjacent sub-pixels 7 are different in the first direction X, while the colors of two adjacent sub-pixels 7 are the same in the second direction Y.

[0119] In some embodiments, such as Figure 3 As shown, the graphic enclosed by the boundary between the non-display area 2 and the display area 1 has a first axis of symmetry 17 parallel to the first direction X and a second axis of symmetry 18 parallel to the second direction Y.

[0120] At least one arc includes a first arc portion 19 and a second arc portion 20 with equal curvature; a first axis of symmetry 17 bisects the first arc portion 19 and the second arc portion 20, and the first arc portion 19 and the second arc portion 20 are symmetrical about a second axis of symmetry 18;

[0121] At least one first sub-pixel opening region 8 in the first pixel 5 is adjacent to the first arc portion 19 or the second arc portion 20.

[0122] The display panel provided in this embodiment of the present disclosure has a first arc portion and a second arc portion that both correspond to a first pixel. That is, the area of ​​the sub-pixel opening region in the display area of ​​the first pixel adjacent to the first arc portion or the second arc portion is reduced. Furthermore, while reducing the area of ​​the sub-pixel opening region in the display area of ​​the first pixel adjacent to the first arc portion or the second arc portion, the aperture ratio of the sub-pixels in the first pixel group located between the first pixel and the second pixel is less than the second aperture ratio and not less than the first aperture ratio. This allows for a gradual transition in the aperture ratios of the first pixel, the third pixel, and the second pixel in the regions corresponding to the first arc portion and the second arc portion. This can alleviate the display defects of colored stripes appearing in the regions corresponding to the first arc portion and the second arc portion, while avoiding the jaggedness caused by large brightness differences between adjacent pixels in the regions corresponding to the first arc portion and the second arc portion. This can improve the display effect and enhance the user experience.

[0123] In some embodiments, such as Figure 3 As shown, at least one non-display area 2 includes: a first non-display area 12 surrounding the display area 1; the area surrounded by the first non-display area 12 is circular in shape; the curved portion 3 includes a circumference corresponding to the boundary between the first non-display area 12 and the display area 1.

[0124] In some embodiments, such as Figure 3 As shown, the area surrounded by the first non-display area 12 coincides with the display area 1, that is, the shape of the display area 1 is circular.

[0125] In some embodiments, the curvature of both the first and second arc portions is 60°.

[0126] It should be noted that the position of the colored stripes is related to the pixel arrangement. When the width of a subpixel in the first direction X is less than its width in the second direction Y, and two adjacent subpixels in the first direction X have different colors but two adjacent subpixels in the second direction Y have the same color, the colored stripes mainly appear in the areas corresponding to the first and second arc sections with an arc of 60°. Taking the non-display area including the first non-display area and the boundary between the first non-display area and the display area including the first and second arc sections as an example, when the first direction is horizontal and the second direction is vertical, the colored stripes mainly appear on the left and right edges of the display area; when the first direction is vertical and the second direction is horizontal, the colored stripes mainly appear on the top and bottom edges of the display area.

[0127] The display panel provided in this embodiment has at least one first sub-pixel opening area in the first pixel adjacent to a first arc portion or a second arc portion with an arc of 60°. This reduces the area of ​​the sub-pixel opening area in the display area of ​​the first pixel adjacent to the first arc portion or the second arc portion with an arc of 60°, thereby reducing the difference in the opening area area between the sub-pixels in the first pixels corresponding to the first arc portion and the second arc portion. Furthermore, the aperture ratio of the sub-pixels in the first pixel group located between the first pixel and the second pixel is less than the second aperture ratio and not less than the first aperture ratio. This can alleviate the display defects of colored stripes appearing in the areas corresponding to the first arc portion and the second arc portion, while also reducing the jaggedness, thereby improving the display effect and enhancing the user experience.

[0128] In some embodiments, such as Figure 4 As shown, the first pixel group 48 includes a plurality of third pixels 49 arranged along the second direction Y.

[0129] In some embodiments, such as Figure 5 As shown, the areas of the multiple third sub-pixel opening regions 50 included in a third pixel 49 are all the same; the areas of the third sub-pixel opening regions 50 included in different third pixels 49 are all the same.

[0130] In practical implementation, when the first pixel group includes multiple third pixels and the area of ​​the opening region of each third pixel, including the third sub-pixel, is the same, such as Figure 5 As shown, each first pixel group can include the same number of third pixels. Figure 5 The example provided illustrates this by showing that each first pixel group includes four third pixels. In practice, the number of third pixels in each first pixel group can be selected according to actual needs; for example, a first pixel group may include two, three, five, or more third pixels.

[0131] Alternatively, in some embodiments, such as Figure 6 As shown, the areas of the multiple third sub-pixel opening regions 50 included in a third pixel 49 are all the same; the areas of the third sub-pixel opening regions 50 included in different third pixels 49 in the first pixel group 48 are not the same.

[0132] In the display panel provided in this embodiment, when the first pixel group includes multiple third pixels, the area of ​​the third sub-pixel opening region included by different third pixels in the first pixel group is different, that is, the third aperture ratio of different third pixels in the first pixel group is different, and the brightness of different third pixels in the first pixel group gradually transitions, further reducing the difference in aperture ratio between the first pixel, the third pixel, and the second pixel, and avoiding the appearance of jagged edges.

[0133] In some embodiments, such as Figure 6 As shown, in the second direction Y, the area of ​​the third sub-pixel opening region 50 included by the plurality of third pixels 49 in the first pixel group 48 gradually increases towards the side closer to the second pixel 6.

[0134] In specific implementation, as follows Figure 3 Taking the display panel shown as an example, the non-display area 2 includes a first non-display area 12, and the boundary between the first non-display area 12 and the display area 1 includes a first arc portion 19 and a second arc portion 20. In the second direction Y, the area of ​​the third sub-pixel opening region included by the plurality of third pixels in the first pixel group gradually increases towards the side closer to the second pixel, meaning that the area of ​​the third sub-pixel opening region included by the plurality of third pixels in the first pixel group gradually increases towards the side closer to the first axis of symmetry 17.

[0135] It should be noted that when there are multiple third pixels arranged sequentially in the first direction, the area of ​​the third sub-pixel opening region included by the multiple third pixels gradually increases towards the side closer to the second pixel in the first direction.

[0136] It should be noted that the brightness variation of the display panel from darkest to brightest ranges from 0 to 255, totaling 256 brightness levels, referred to as 256 grayscale levels. The grayscale level corresponding to the second pixel is L255. Since the first aperture ratio is less than the second aperture ratio, when the aperture area of ​​the first sub-pixel is a complete rectangle, the grayscale level corresponding to the complete rectangular first sub-pixel aperture area is the first preset grayscale level Lr, where Lr is less than L255. The aperture ratio of the third pixel is not less than the first preset grayscale level and is less than L255. In the display panel provided in this embodiment, in the second direction, the area of ​​the third sub-pixel aperture area included by multiple third pixels in the first pixel group gradually increases towards the side closer to the second pixel. That is, grayscale transition is achieved by adjusting the area of ​​the third sub-pixel aperture area in the first pixel group, thereby gradually increasing the grayscale level of multiple third pixels in the first pixel group towards the side closer to the second pixel in the second direction, realizing a gradual transition of grayscale between Lr and L255.

[0137] It should be noted that the greater the difference in aperture ratio and brightness between adjacent pixels, the more noticeable the jagged edges. In the display panel provided in this embodiment, the grayscale of multiple third pixels in the first pixel group gradually increases towards the second pixel, and the brightness of different third pixels in the first pixel group gradually increases. Compared to the case where the aperture ratios of multiple third pixels in the first pixel group are all the same, the difference in aperture ratio between adjacent pixels in the sequentially arranged first, third, and second pixels is further reduced, thereby further reducing the brightness difference between adjacent pixels, which can further alleviate the jagged edges and improve the display effect.

[0138] In some embodiments, the ratio of the area of ​​each first sub-pixel aperture region to the area of ​​the corresponding sub-pixel in the display area is a first preset value. That is, the first aperture ratio is the first preset value.

[0139] In some embodiments, such as Figure 6 As shown, the plurality of first pixels 5 include a plurality of first type first pixels 51, a plurality of second type first pixels 52, and a plurality of third type first pixels 53;

[0140] Each first type of first pixel 51 includes multiple sub-pixels that overlap with the display area, and the area of ​​the opening region 8 of each first sub-pixel included in the first type of first pixel 51 is greater than or equal to the second preset value.

[0141] The second type of first pixel 52 includes multiple sub-pixels that overlap with the display area, and the area of ​​the opening area 8 of some of the first sub-pixels included in the second type of first pixel 52 is smaller than the second preset value.

[0142] The third type of first pixel 53 includes multiple sub-pixels, only some of which overlap with the display area.

[0143] In some embodiments, the ratio of the second preset value to the area of ​​the sub-pixel region in the first pixel is half of the first preset value. That is, the second preset value is half of the area of ​​the complete rectangular first sub-pixel aperture region corresponding to the first aperture ratio.

[0144] In specific implementation, for a first pixel whose sub-pixels all overlap with the display area, when the area of ​​the opening area of ​​each first sub-pixel in the first pixel is greater than or equal to half the area of ​​the opening area of ​​the complete rectangular first sub-pixel, the first pixel is a first type of first pixel; when the area of ​​the opening area of ​​some first sub-pixels in the first pixel is less than half the area of ​​the opening area of ​​the complete rectangular first sub-pixel, the first pixel is a second type of first pixel.

[0145] In practical implementation, because the first pixel is adjacent to the curved portion, even if multiple first pixels correspond to the first aperture ratio, the brightness of different types of first pixels will differ. For example... Figure 6 As shown, some sub-pixels in the third type of first pixel 53 are completely located in the non-display area, that is, the third type of first pixel 53 does not include the three first sub-pixel opening areas 8. Therefore, the brightness of the third type of first pixel 53 cannot reach the brightness corresponding to the first preset grayscale Lr; Figure 6 As shown, the second type of first pixel 52 includes multiple sub-pixels that overlap with the display area. That is, the second type of first pixel 52 includes three first sub-pixel opening areas 8. However, the area of ​​some first sub-pixel opening areas 8 in the second type of first pixel 52 is less than half the area of ​​the complete rectangular first sub-pixel opening area. For example, the area of ​​the blue sub-pixel B included in the second type of first pixel 52 is less than half the area of ​​the red sub-pixel R included in the second type of first pixel 52. Therefore, the brightness of the blue sub-pixel B cannot reach the brightness corresponding to the first preset grayscale Lr. Thus, the brightness of the second type of first pixel cannot reach the brightness corresponding to the first preset grayscale Lr. Figure 6 As shown, the first type of first pixel 51 includes multiple sub-pixels that overlap with the display area. Specifically, the first type of first pixel 51 includes three first sub-pixel opening areas 8, and the area of ​​some of the first sub-pixel opening areas 8 in the first type of first pixel 51 is greater than or equal to half the area of ​​a complete rectangular first sub-pixel opening area. For example, if the area of ​​the blue sub-pixel B in the first type of first pixel 51 is greater than half the area of ​​the red sub-pixel R in the first type of first pixel 51, then the brightness of the blue sub-pixel B can reach the brightness corresponding to the first preset grayscale Lr. Therefore, the brightness of the first type of first pixel can reach the brightness corresponding to the first preset grayscale Lr. In other words, the brightness of the first type of first pixel is greater than the brightness of the second type of first pixel, and the brightness of the second type of first pixel is greater than the brightness of the third type of first pixel.

[0146] In practical implementation, multiple pixels are divided into multiple pixel columns arranged along a first direction, and each pixel column includes multiple pixels arranged along a second direction. In a pixel column, for any two adjacent first pixels located on one side of a first pixel group, the number of first sub-pixel opening regions in the first pixel closer to the first pixel group is not less than the number of first sub-pixel opening regions in the first pixel farther from the first pixel group.

[0147] In practical implementation, in a single pixel column, such as Figure 6 As shown, one side of the first pixel group 48 may include multiple first pixels 5. For example, the multiple first pixels 5 may include a first type of first pixel 51 and a third type of first pixel 53, or the multiple first pixels 5 may include a second type of first pixel 52 and a third type of first pixel 53, or the multiple first pixels 5 may include a first type of first pixel 51, a second type of first pixel 52, and a third type of first pixel 53. When the multiple first pixels 5 on one side of the first pixel group 48 include a first type of first pixel 51 and a third type of first pixel 53, the first type of first pixel 51 is located between the first pixel group 48 and the third type of pixel 53. When the multiple first pixels 5 on one side of the first pixel group 48 include a second type of first pixel 52 and a third type of first pixel 53, the second type of first pixel 52 is located between the first pixel group 48 and the third type of pixel 53. When the plurality of first pixels 5 on one side of the first pixel group 48 includes a first type of first pixel 51, a second type of first pixel 52, and a third type of first pixel 53, the first type of first pixel 51 is located between the first pixel group 48 and the third type of first pixel 53, and the second type of first pixel 52 is located between the first type of first pixel 51 and the third type of first pixel 53. Therefore, even if the brightness of the different types of first pixels is different, in the second direction and towards the side closer to the first axis of symmetry, the brightness of the different types of first pixels gradually increases.

[0148] It should be noted that the first preset grayscale Lr corresponding to the first preset value can be selected according to actual needs, such as considering the area of ​​the sub-pixel, the area of ​​the first sub-pixel opening area, etc.

[0149] In practice, the areas of the opening regions of the third sub-pixels included in different third pixels in the first pixel group are not the same, meaning that the third aperture ratios of different third pixels in the first pixel group are not the same, and the gray levels corresponding to different third pixels in the first pixel group are also different. When the areas of the opening regions of the third sub-pixels included in multiple third pixels in the first pixel group gradually increase towards the side closer to the second pixel, the gray levels of multiple third pixels in the first pixel group gradually increase towards the side closer to the second pixel, and the gray level of the third pixel adjacent to the second pixel is less than L255.

[0150] In some embodiments, such as Figure 6As shown, in the second direction Y, in the third pixel 49 adjacent to the first pixel 51 of the first class, the ratio of the area of ​​the third sub-pixel opening region 50 to the area of ​​the sub-pixel in the third pixel 49 is greater than a first preset value.

[0151] In practical implementation, since the brightness of the first pixel of the first type can reach the brightness corresponding to the first preset value, the ratio of the area of ​​the opening region of the third sub-pixel in the third pixel adjacent to the first pixel of the first type to the area of ​​the sub-pixel in the third pixel is greater than the first preset value. That is, the aperture ratio of the third pixel adjacent to the first pixel of the first type is greater than the first preset value, the gray level of the third pixel adjacent to the first pixel of the first type is greater than the first preset gray level, and the brightness of the third pixel adjacent to the first pixel of the first type is greater than the brightness corresponding to the first preset value. Since the brightness of multiple third pixels in the first pixel group gradually increases towards the side closer to the second pixel in the second direction, and the brightness of the third pixel is less than the brightness of the second pixel, the brightness of the first pixel of the first type, the different third pixels and second pixels in the first pixel group have a gradually increasing transition trend. In the sequentially arranged first pixel, third pixel and second pixel, the brightness difference between adjacent pixels is further reduced, which can alleviate the jaggedness and improve the display effect.

[0152] In practical implementation, the gray levels of multiple third pixels located between the first pixel and the second pixel of the first type decrease sequentially within a range greater than a first preset gray level and less than L255. The differences between the gray levels of the third pixels adjacent to the first pixel of the first type and the first preset gray level, the differences between the gray levels of multiple third pixels in the first pixel group, and the differences between the gray levels of the third pixels adjacent to the second pixel and L255 can be selected according to actual needs. For example, they can be selected based on the first preset gray level and the number of third pixels in the first pixel group.

[0153] In some embodiments, such as Figure 6 As shown, in the second direction Y, in the third pixel 49 adjacent to the second type first pixel 52, the ratio of the area of ​​the third sub-pixel opening region 50 to the area of ​​the sub-pixel in the third pixel 49 is equal to the first preset value.

[0154] In practical implementation, since the brightness of the second type of first pixel does not reach the brightness corresponding to the first preset value, the ratio of the area of ​​the opening region of the third sub-pixel in the third pixel adjacent to the second type of first pixel to the area of ​​the sub-pixel in the third pixel is equal to the first preset value. That is, the aperture ratio of the third pixel adjacent to the second type of first pixel is equal to the first preset value, the grayscale of the third pixel adjacent to the second type of first pixel is equal to the first preset grayscale, and the brightness of the corresponding third pixel adjacent to the second type of first pixel is equal to the brightness corresponding to the first preset value, and the brightness of the third pixel adjacent to the second type of first pixel is greater than the brightness of the second type of first pixel. Since the brightness of multiple third pixels in the first pixel group gradually increases towards the side closer to the second pixel in the second direction, and the brightness of the third pixel is less than the brightness of the second pixel, the brightness of the second type of first pixel, different third pixels in the first pixel group, and second pixels shows a gradually increasing transition trend. In the sequentially arranged first pixel, third pixel, and second pixel, the brightness difference between adjacent pixels is further reduced, which can alleviate the jaggedness and improve the display effect.

[0155] In practical implementation, the grayscale of the third pixel located between the first pixel and the second pixel of the second type, and the grayscale of the third pixel adjacent to the first pixel of the second type, is the first preset grayscale. The grayscale of the remaining third pixels decreases progressively within the range greater than the first preset grayscale and less than L255. The differences between the grayscale of multiple third pixels in the first pixel group, and the differences between the grayscale of the third pixel adjacent to the second pixel and L255, can be selected according to actual needs. For example, they can be selected based on the first preset grayscale and the number of third pixels in the first pixel group.

[0156] In some embodiments, in the second direction, the number of third pixels in the first pixel group adjacent to the first pixel of the first class is m, and the number of third pixels in the first pixel group adjacent to the first pixel of the second class is n, where m and n are both integers greater than 1, and nm = 1.

[0157] In some embodiments, such as Figure 6 As shown, in the second direction Y, the first pixel group 48 adjacent to the first pixel 51 of the first type is the first pixel group 54 of the first type, and the first pixel group 48 adjacent to the first pixel 52 of the second type is the first pixel group 55 of the second type.

[0158] In specific implementation, in the second direction Y, the aperture ratios of the m third pixels in the first pixel group 54 of the first type correspond one-to-one with the aperture ratios of the m third pixels in the second pixel group 55 that are closest to the second pixel. For example, in the second direction Y, and in the direction closest to the second pixel, the aperture ratios of the third pixels in the first pixel group of the first type are cm, ..., c2, c1, and the aperture ratios of the third pixels in the second pixel group of the first type are cn, cm, ..., c2, c1. Correspondingly, in the second direction Y, the gray levels of the m third pixels in the first pixel group 54 of the first type correspond one-to-one with the gray levels of the m third pixels in the second pixel group that are closest to the second pixel. For example, in the second direction Y, and in the direction closest to the second pixel, the gray levels of the third pixels in the first pixel group of the first type are Lrm, ..., Lr2, Lr1, and the gray levels of the third pixels in the second pixel group of the first type are Lr, Lrm, ..., Lr2, Lr1.

[0159] In practical implementation, the specific grayscale of each third pixel in the first pixel group can be selected based on the number of third pixels in the first pixel group, the first preset grayscale, and the grayscale curve. The grayscale transmittance relationship curve is shown below. Figure 7 As shown.

[0160] In some embodiments, the grayscale difference between the third pixel adjacent to the second pixel in the first pixel group and the second pixel is approximately an integer multiple of 16. That is, the grayscale difference between the third pixel adjacent to the second pixel in the first pixel group and the second pixel is 16H + J, where H is a positive integer and J is, for example, greater than or equal to -5 and less than or equal to 5. In a specific implementation, H = 1, J = 0, and the grayscale difference between the third pixel adjacent to the second pixel in the first pixel group and the second pixel is 16, meaning the grayscale of the third pixel adjacent to the second pixel in the first pixel group is L239.

[0161] In some embodiments, the difference in grayscale between any two adjacent third pixels in the first pixel group is approximately an integer multiple of 16.

[0162] In practical implementation, "the difference in gray levels between any two adjacent third pixels in the first pixel group is approximately a multiple of 16" means that the difference in gray levels between any two adjacent third pixels in the first pixel group is a multiple of 16, or that the difference in gray levels between any two adjacent third pixels in the first pixel group is approximately a multiple of 16. For example, the difference in gray levels between any two adjacent third pixels in the first pixel group is 16H+J, where H is a positive integer, and J is, for example, greater than or equal to -5 and less than or equal to 5.

[0163] In practice, the difference in grayscale between any two adjacent third pixels in the first pixel group can be, for example, 15, 16, 18, 19, 31, 32, 33, etc.

[0164] In practical implementation, taking the first pixel group of the second type as an example, if the grayscale of the third pixel with the lowest brightness is L127 and the grayscale of the third pixel with the highest brightness is L239, and if the grayscale differences of each third pixel are all integer multiples of 32, then the number of third pixels with grayscale transitions is small, and the anti-aliasing effect is not obvious. If the grayscale differences of each third pixel are all integer multiples of 8, then the number of third pixels with grayscale transitions is large, the design is complex, and it will affect the display effect of the display area.

[0165] The display panel provided in this application embodiment has a grayscale difference between any two adjacent third pixels in the first pixel group that is approximately an integer multiple of 16. This can ensure the number of third pixels with grayscale transition and the anti-aliasing effect while avoiding affecting the display effect of the display panel.

[0166] In specific implementation, according to, for example Figure 7 As shown in the grayscale-transmittance relationship curve, at low grayscale levels, the brightness change is smaller with increasing grayscale, while at high grayscale levels, the brightness change is larger with increasing grayscale. The specific grayscale difference between two adjacent third pixels in the first pixel group can be selected based on the trend of the grayscale curve.

[0167] In some embodiments, the grayscale difference between two adjacent third pixels in the first pixel group is not exactly the same.

[0168] In practical implementation, for example, a range with a grayscale level less than or equal to L220 is considered a low grayscale range, and a range with a grayscale level greater than L220 is considered a high grayscale range. It can be set so that the grayscale difference between adjacent third pixels in the low grayscale range is greater than the grayscale difference between adjacent third pixels in the high grayscale range. Since the grayscale brightness difference in the low grayscale range of the grayscale curve is relatively small, the grayscale differences between different adjacent third pixels in the first pixel group are not entirely the same. Furthermore, since the grayscale difference between adjacent third pixels in the low grayscale range is greater than the grayscale difference between adjacent third pixels in the high grayscale range, uniform brightness differences can be achieved among multiple third pixels in the first pixel group. This, in turn, achieves uniform brightness differences among the first pixel, the first pixel group, and the second pixel, thus mitigating the jaggedness caused by large brightness differences while also reducing color stripes.

[0169] In practice, in the low grayscale range, the grayscale difference between adjacent third pixels can be approximately twice 16, while in the high grayscale range, the grayscale difference between adjacent third pixels can be approximately 16. For example, in the low grayscale range, the grayscale difference between adjacent third pixels is 31, and in the high grayscale range, the grayscale difference between adjacent third pixels is 19.

[0170] In some embodiments, such as Figure 6 As shown, n = 5, m = 4;

[0171] The gray level corresponding to the second pixel is L255, and the gray level corresponding to the first pixel is L127; that is, the first preset gray level is L127.

[0172] The gray levels corresponding to the third pixel in the first pixel group adjacent to the first pixel of the second type are L127, L158, L189, L220, and L239, respectively.

[0173] The gray levels corresponding to the third pixel in the first pixel group adjacent to the first pixel of the first class are L158, L189, L220, and L239, respectively.

[0174] Alternatively, in some embodiments, such as Figure 8 As shown, n = 4, m = 3;

[0175] The gray level corresponding to the second pixel is L255, and the gray level corresponding to the first pixel is L158; that is, the first preset gray level is L158.

[0176] The gray levels corresponding to the third pixel in the first pixel group adjacent to the first pixel of the second type are L158, L189, L220, and L239, respectively.

[0177] The gray levels corresponding to the third pixel in the first pixel group adjacent to the first pixel of the first class are L189, L220, and L239, respectively.

[0178] It should be noted that the aperture ratio of the first pixel and the first pixel group is smaller than the aperture ratio of the second pixel, i.e., as shown below. Figure 6 As shown, the areas containing the first pixel 5, the first pixel group 48, and the second pixel 6 adjacent to the first pixel group 48 can be considered as areas of aperture ratio transition, i.e., areas of brightness transition. The areas corresponding to the remaining second pixel 6 are areas of non-aperture ratio transition, i.e., areas of non-brightness transition. There is a boundary 65 between the brightness transition area K and the non-brightness transition area Z, and the visual perception of this boundary depends on the number of pixels in the brightness transition area. The fewer pixels in the brightness transition area, the less obvious the visual boundary of the abrupt change.

[0179] and Figure 6 Compared to the provided display panels, the embodiments of this disclosure provide, such as Figure 8 The display panel shown increases the grayscale corresponding to the first pixel and decreases the number of third pixels in the first pixel group. This can achieve uniform brightness differences between adjacent pixels and alleviate jaggedness, while avoiding abrupt boundaries between areas of brightness transition and areas of non-brightness transition, thus improving the display effect.

[0180] In some embodiments, such as Figure 9 , Figure 10As shown, the plurality of pixels 4 also includes a plurality of sixth pixels 59 in the region outside the first pixel 5 that are adjacent to the curved portion 3;

[0181] Each sixth pixel 59 includes at least one sixth sub-pixel opening area 60 located in the display area 1. At least one sixth sub-pixel opening area 60 in the sixth pixel 59 is adjacent to the curved portion 3, and at least part of the sixth sub-pixel opening area 60 adjacent to the curved portion 3 is non-rectangular in shape.

[0182] The ratio of the area of ​​each sixth sub-pixel aperture region 60 to the area of ​​the corresponding sub-pixel 7 in the display area 1 is equal to the ratio of the area of ​​the second sub-pixel aperture region 9 to the area of ​​the sub-pixel 7 in the second pixel 6. That is, the aperture ratio of the sixth pixel is equal to the second aperture ratio.

[0183] It should be noted that since the position of the colored stripes is related to the arrangement of pixels, the pixel corresponding to the curve is set as the first pixel in the position where colored stripes are likely to appear. In the area outside the first pixel, the aperture ratio of the pixel corresponding to the curve is equal to the second aperture ratio and no serious colored stripes will appear.

[0184] In some embodiments, the pixels adjacent to the curved portion in the area other than the first pixel are all sixth pixels.

[0185] Alternatively, in some embodiments, such as Figure 11 , Figure 12 As shown, the plurality of pixels 4 further includes: a plurality of second pixel groups 56 adjacent to the curved portion 3 in at least a portion of the region outside the first pixel 5; the second pixel group 56 includes a plurality of fourth pixels 57 arranged along the second direction Y;

[0186] Each fourth pixel 57 includes at least one fourth sub-pixel opening area 58 located in the display area 1. At least one fourth sub-pixel opening area 58 in the fourth pixel 57 is adjacent to the curved portion 3, and the shape of the fourth sub-pixel opening area 58 that is at least partially adjacent to the curved portion 3 is non-rectangular.

[0187] The ratio of the area of ​​each fourth sub-pixel opening region 58 to the area of ​​the corresponding sub-pixel in the display area 1 is greater than the ratio of the area of ​​each first sub-pixel opening region 8 to the area of ​​the corresponding sub-pixel in the display area 1; and the ratio of the area of ​​each fourth sub-pixel opening region 58 to the area of ​​the corresponding sub-pixel in the display area 1 is less than the ratio of the area of ​​the second sub-pixel opening region to the area of ​​the sub-pixel in the second pixel.

[0188] In practical implementation, the ratio of the area of ​​the fourth sub-pixel aperture region to the area of ​​the corresponding sub-pixel in the display area is the fourth aperture ratio, that is, the fourth aperture ratio is greater than the first aperture ratio and less than the second aperture ratio.

[0189] It should be noted that since the position of the colored stripes is related to the arrangement of pixels, the pixel corresponding to the arc is set as the first pixel in the position where colored stripes are likely to appear. In the area outside the first pixel, the aperture ratio of the pixel corresponding to the arc is greater than the first aperture ratio and there will be no serious colored stripes.

[0190] The display panel provided in this embodiment has a second pixel group set in the area corresponding to the curve and in the area adjacent to the first pixel. The aperture ratio of the fourth sub-pixel in the second pixel group is greater than the first aperture ratio and less than the second aperture ratio. The gray level of the fourth sub-pixel in the second pixel group is greater than the gray level of the first pixel and less than the gray level of the second pixel. That is, a gray level transition area is also set in the area of ​​the curve adjacent to the first pixel to achieve a smooth brightness transition and avoid the visually abrupt boundary between the brightness transition area and the brightness non-transition area, thereby improving the display effect.

[0191] It should be noted that, Figure 11 , Figure 12 for Figure 3 Enlarged schematic diagram of region B in the middle.

[0192] In some embodiments, when the plurality of pixels also includes a fourth pixel, the sixth pixel is adjacent to the curved portion in the region outside the first pixel and the fourth pixel.

[0193] In some embodiments, such as Figure 11 , Figure 12 As shown, in a second pixel group 56, for different fourth pixels 57, the ratio of the area of ​​the fourth sub-pixel opening region 58 to the area of ​​the sub-pixel corresponding to the fourth sub-pixel opening region 58 in the display area 1 is the same.

[0194] In some embodiments, such as Figure 11 , Figure 12 As shown, in the extension direction of the curve portion 3, and in the direction from the first pixel 5 to the adjacent second pixel group 56, in different second pixel groups 56, the ratio of the area of ​​the fourth sub-pixel opening region 58 to the area of ​​the sub-pixel corresponding to the fourth sub-pixel opening region 58 in the display area 1 increases sequentially.

[0195] That is, in the extension direction of the curve and in the direction from the first pixel to the adjacent second pixel group, the gray levels of different second pixel groups increase sequentially, so as to achieve a smooth transition of brightness among multiple second pixel groups, avoid the abrupt boundary between the brightness transition area and the brightness non-transition area, and improve the display effect.

[0196] It should be noted that multiple pixels are divided into multiple pixel rows extending along the first direction and arranged along the second direction, and multiple pixel columns extending along the second direction and arranged along the first direction. The second pixel group is located between the first pixel and the sixth pixel, and different second pixel groups are located in different pixel rows. The gray levels of different second pixel groups increase sequentially, which can achieve a smooth transition of brightness in the first direction and weaken the boundary between the abrupt transition area and the non-transition area of ​​brightness.

[0197] In some embodiments, in the extension direction of the curved portion and in the direction from the first pixel to its adjacent second pixel group, the grayscale difference between the last second pixel group and the second pixel is approximately an integer multiple of 16, i.e., 16H+J. In a specific implementation, H=1, J=0 can be set, and in the extension direction of the curved portion and in the direction from the first pixel to its adjacent second pixel group, the grayscale difference between the last second pixel group and the second pixel is 16, i.e., in the extension direction of the curved portion and in the direction from the first pixel to its adjacent second pixel group, the grayscale of the last second pixel group is L239.

[0198] In some embodiments, in the extension direction of the curve portion and in the direction from the first pixel to its adjacent second pixel group, the grayscale difference between any two adjacent second pixel groups is 16H+J. That is, in the extension direction of the curve portion and in the direction from the first pixel to its adjacent second pixel group, the grayscale difference between any two adjacent second pixel groups is approximately an integer multiple of 16.

[0199] In some embodiments, in the extension direction of the curved portion, the difference between the gray level of the adjacent second pixel group and the gray level of the first pixel is 16H+J. In a specific implementation, for example, H=2, J=-1, when the first preset gray level is L127, the gray level of the second pixel group adjacent to the first pixel is, for example, L158.

[0200] In some embodiments, the area between the first pixel and the sixth pixel includes four second pixel groups, with the first pixel pointing in the direction of the sixth pixel. When the first preset gray level is L127, the gray levels of the four second pixel groups are L158, L189, L220, and L239, respectively.

[0201] It should be noted that, Figure 11 , 12 The example described uses the case where each second pixel group includes two fourth pixels. In practice, the second pixel group may also include a larger number of fourth pixels.

[0202] In specific implementations, the fourth pixel can be either a first-type fourth pixel or a second-type fourth pixel. The first-type fourth pixel includes fewer than three fourth sub-pixel openings, while the second-type fourth pixel includes three fourth sub-pixel openings. A second pixel group can include both first-type and second-type fourth pixels. Within a second pixel group, for any two adjacent fourth pixels, the fourth pixel closer to the first pixel has at least as many fourth sub-pixel openings as the fourth pixel further away from the first pixel.

[0203] In some embodiments, such as Figure 11 , Figure 12 As shown, the multiple pixels 4 also include: the third pixel group 62;

[0204] In the second direction Y, the third pixel group 62 is located between the second pixel group 56 and the second pixel 6;

[0205] The third pixel group 62 includes at least one fifth pixel 63; the fifth pixel 63 includes: a fifth sub-pixel opening region 64 corresponding to the sub-pixel, the fifth sub-pixel opening region 64 being rectangular in shape;

[0206] The ratio of the area of ​​the fifth sub-pixel opening region 64 in the third pixel group 62 to the area of ​​the sub-pixel in the fifth pixel 63 is not less than the ratio of the area of ​​the fourth sub-pixel opening region 58 adjacent to the third pixel group 62 to the area of ​​the sub-pixel corresponding to the fourth sub-pixel opening region 58 in the display area 1; the ratio of the area of ​​the fifth sub-pixel opening region 64 to the area of ​​the sub-pixel in the fifth pixel 63 is less than the ratio of the area of ​​the second sub-pixel opening region 9 to the area of ​​the sub-pixel in the second pixel 6.

[0207] It should be noted that the ratio of the area of ​​the aperture region of the fifth sub-pixel in the third pixel group to the area of ​​the sub-pixel in the fifth pixel is the fifth aperture ratio. The fifth aperture ratio is not less than the fourth aperture ratio corresponding to the adjacent second pixel group, and the fifth aperture ratio is less than the second aperture ratio. That is, the gray level of the fifth pixel in the third pixel group is not less than the gray level corresponding to the adjacent second pixel group, and the gray level of the fifth pixel in the third pixel group is less than L255.

[0208] The display panel provided in this embodiment further increases the grayscale transition area by setting a third pixel group between the second pixel group and the second pixel, thereby achieving a smooth brightness transition. This can further alleviate the abrupt boundary between the visually transitional brightness area and the non-transitional brightness area, and improve the display effect.

[0209] It should be noted that different second pixel groups are located in different pixel rows and different pixel columns. Therefore, for the multiple third pixel groups corresponding to the multiple second pixel groups between the first pixel and the sixth pixel, the multiple third pixel groups are also located in different columns, and the multiple third pixel groups are arranged sequentially along the first direction. Setting the third pixel group to further increase the grayscale transition area can further achieve a smooth transition of brightness in the first direction and weaken the boundary between the brightness transition area and the brightness non-transition area.

[0210] In some embodiments, such as Figure 11 , Figure 12 As shown, in the extension direction of the curve portion 3, and in the direction from the first pixel 5 to the adjacent second pixel group 56, the number of fifth pixels in different third pixel groups 62 decreases sequentially.

[0211] In practical implementation, since multiple third pixel groups are arranged sequentially along the first direction, when the number of fifth pixels in different third pixel groups decreases sequentially on the side of the first pixel that is close to the adjacent second pixel group, the number of pixels with grayscale transition in the first direction can be reduced, thereby further realizing a smooth transition of brightness in the first direction and weakening the boundary between the brightness transition area and the brightness non-transition area.

[0212] In some embodiments, the grayscale difference between the fifth pixel adjacent to the second pixel and the second pixel is approximately an integer multiple of 16. That is, the grayscale difference between the third pixel adjacent to the second pixel and the second pixel is 16H+J. For example, H=1, J=0, the grayscale of the fifth pixel adjacent to the second pixel in the third pixel group is L239.

[0213] In some embodiments, when the third pixel group includes a plurality of fifth pixels, in the second direction, the gray levels of the plurality of fifth pixels increase sequentially toward the side closer to the second pixel.

[0214] In some embodiments, in the second direction, and in the direction from the second pixel group to the adjacent third pixel group, the grayscale difference between any two adjacent fifth pixels in the third pixel group is: 16H+J.

[0215] In some embodiments, the adjacent fifth pixel has the same grayscale as the second pixel group.

[0216] In some embodiments, when the region between the first pixel and the sixth pixel includes four second pixel groups, and the gray levels of the four second pixel groups are L158, L189, L220, and L239 respectively, the third pixel group adjacent to the second pixel group with gray level L239 includes only one fifth pixel, and the gray level of the fifth pixel is L239; the third pixel group adjacent to the second pixel group with gray level L220 includes two fifth pixels, and the gray levels of the fifth pixels are L220 and L239 respectively; the third pixel group adjacent to the second pixel group with gray level L189 includes three fifth pixels, and the gray levels of the fifth pixels are L189, L220, and L239 respectively; the third pixel group adjacent to the second pixel group with gray level L158 includes four fifth pixels, and the gray levels of the fifth pixels are L158, L189, L220, and L239 respectively.

[0217] The display panel provided in this application embodiment has a second pixel group and a third pixel group with grayscale transition in the area outside the first pixel. In this area, since multiple second pixel groups are arranged in a row along the first direction and multiple third pixel groups are arranged sequentially along the first direction, when the grayscale of multiple second pixel groups increases sequentially and the number of fifth sub-pixels in different third pixel groups decreases sequentially when the first pixel is close to the side of the second pixel group adjacent to it, the number of pixels with grayscale transition in the first direction can be reduced while increasing the grayscale transition area, thereby further realizing a smooth transition of brightness in the first direction and weakening the boundary between the brightness transition area and the brightness non-transition area.

[0218] In some embodiments, such as Figure 13 As shown, the display panel includes:

[0219] Array substrate 31, such as Figure 13 As shown, it includes: a first substrate 36 and a sub-pixel 7 located on one side of the first substrate;

[0220] The opposing substrate 32 is disposed opposite to the array substrate 31 and includes: a second substrate 35 and a light-shielding layer 13 located on the side of the second substrate 35 facing the array substrate 31.

[0221] The liquid crystal layer 33 is located between the array substrate 31 and the opposing substrate 32.

[0222] That is, the display panel provided in the embodiments of this application is a liquid crystal display panel.

[0223] In a specific implementation, the array substrate also includes multiple horizontally and vertically intersecting scan lines and data lines, which define the area of ​​a sub-pixel. In some embodiments, such as Figure 14As shown, sub-pixel 7 includes a thin-film transistor 38 and a pixel electrode 39 electrically connected to the thin-film transistor 38. The thin-film transistor 38 includes a gate 40, a source 41, a drain 42, and an active layer 43. Figure 13 Taking a thin-film transistor (TFT) as an example with a bottom-gate structure, the array substrate 31 further includes: a buffer layer 44 located between the gate 40 and the first substrate 36; a gate insulating layer 45 located between the gate 40 and the active layer 43; and a passivation layer 46 located between the drain 42 and the pixel electrode 39. In a specific implementation, the gate of the TFT is electrically connected to the scan line, the source of the TFT is electrically connected to the data line, and the drain of the TFT is electrically connected to the pixel electrode. The array substrate or the opposing substrate also includes a common electrode.

[0224] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 , Figure 10 , Figure 12 As shown, the light-shielding layer 13 includes: a first light-shielding portion 14, a second light-shielding portion 15, and a plurality of sub-pixel opening regions 37; the orthographic projection of the first light-shielding portion 14 onto the first substrate falls into the first non-display area 12, and the edge of the orthographic projection of the first light-shielding portion 14 on the side near the display area coincides with the boundary between the first non-display area and the display area, and the orthographic projection of the first light-shielding portion 14 on the first substrate covers at least part of the orthographic projection of the first pixel 5 on the first substrate; the second light-shielding portion 15 is located between adjacent sub-pixel opening regions 37; the plurality of sub-pixel opening regions 37 include: a plurality of first sub-pixel opening regions 8, a plurality of second sub-pixel opening regions 9, and a plurality of third sub-pixel opening regions 50.

[0225] In some embodiments, such as Figure 10 As shown, when the display panel also includes a sixth pixel 59, the plurality of sub-pixel opening areas 37 also include: a plurality of sixth sub-pixel opening areas 60.

[0226] In some embodiments, such as Figure 12 As shown, when the display panel also includes a fourth pixel 57, the plurality of sub-pixel opening areas 37 also include: a plurality of fourth sub-pixel opening areas 58.

[0227] In some embodiments, such as Figure 12 As shown, when the display panel also includes a fifth pixel 63, the plurality of sub-pixel opening areas 37 also include: a plurality of fifth sub-pixel opening areas 64.

[0228] In some embodiments, such as Figure 5 , Figure 6 , Figure 8 , Figure 10 , Figure 12As shown, the area surrounded by the first light-shielding part 14 coincides with the display area in the orthographic projection of the second substrate.

[0229] The display panel provided in this application defines the boundary between the display area and the first non-display area by a first light-shielding part, and defines the size of the sub-pixel opening area by a second light-shielding part. When the boundary between the display area and the first non-display area includes a curved portion, that is, the shape surrounded by the first non-display area is non-rectangular, the first light-shielding part covers part of the sub-pixel, and the process of defining the range of the display area by the first light-shielding part is simple and easy to implement.

[0230] In specific implementation, such as Figure 4 , Figure 11 Let's take an example where the sub-pixels in each row are not exactly the same. Of course, it could also be like... Figure 9 As shown, the sub-pixels 7 are arranged in a rectangular array, meaning that the number of sub-pixels 7 in each row and each column is the same. Subsequently, the display area can be defined by the first light-shielding portion. In this way, with the same sub-pixel size, the mask used in the patterning process of the rectangular display area can be applied to the fabrication of the display panel for the non-rectangular display area, saving costs. It should be noted that in some embodiments, such as... Figure 9 As shown, the plurality of pixels 4 also includes a dummy pixel 16 that is completely located in the first non-display area 12. That is, the dummy pixel 16 is completely covered by the first light-shielding part. Of course, in specific implementations, the pattern of the sub-pixel array arrangement in the array substrate can be set according to actual needs.

[0231] In some embodiments, such as Figure 13 As shown, the opposing substrate 32 further includes a plurality of color resists 34 located on the side of the second substrate 36 facing the liquid crystal layer 33; the color resists 34 are located within the opening region.

[0232] When a pixel includes: a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel, in some embodiments, such as Figure 13 As shown, the multiple color resists 34 include: a red color resist r corresponding to a red sub-pixel, a green color resist g corresponding to a green sub-pixel, and a blue color resist b corresponding to a blue sub-pixel.

[0233] The following example illustrates the distance between sub-pixel openings, assuming each sub-pixel corresponds to only one sub-pixel opening. It should be noted that the distance between sub-pixel openings is the width of the second light-blocking portion.

[0234] In some embodiments, in a first direction, the distance between two adjacent first sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions, and in a second direction, the distance between two adjacent first sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions.

[0235] In some embodiments, for adjacent first pixels and third pixels with the same gray level, in a first direction, the distance between two adjacent first sub-pixel opening regions is equal to the distance between two adjacent third sub-pixel opening regions; in a second direction, the distance between an adjacent third sub-pixel opening region and a first sub-pixel opening region is equal to the distance between two adjacent first sub-pixel opening regions, and the distance between an adjacent third sub-pixel opening region and a first sub-pixel opening region is greater than the distance between two adjacent second sub-pixel opening regions.

[0236] In some embodiments, among third pixels whose grayscale is different from that of the first pixel, in the first direction, the distance between two adjacent third sub-pixel openings is less than the distance between two adjacent first sub-pixel openings, and the distance between two adjacent third sub-pixel openings is greater than the distance between two adjacent second sub-pixel openings. Furthermore, in a first pixel group, among multiple third pixels with different grayscales, for multiple third pixels with sequentially increasing grayscales, in the first direction, the distance between two adjacent third sub-pixel openings of different third pixels sequentially decreases, and in the second direction, the distance between two adjacent third sub-pixel openings sequentially decreases.

[0237] In some embodiments, for adjacent third pixels and second pixels in the second direction, in the first direction, the distance between two adjacent third sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions; and in the second direction, the distance between adjacent third sub-pixel opening regions and second sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions in the second direction.

[0238] In some embodiments, for each second pixel group, in the first direction, the distance between two adjacent fourth sub-pixel opening regions is less than the distance between two adjacent first sub-pixel opening regions, and the distance between two adjacent fourth sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions; and for each second pixel group, in the second direction, the distance between two adjacent fourth sub-pixel opening regions is less than the distance between two adjacent first sub-pixel opening regions, and the distance between two adjacent fourth sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions.

[0239] In some embodiments, for a plurality of second pixel groups with sequentially increasing gray levels, in a first direction, the distance between two adjacent fourth sub-pixel opening regions of different second pixel groups decreases sequentially, and in a second direction, the distance between two adjacent fourth sub-pixel opening regions of different second pixel groups decreases sequentially.

[0240] In some embodiments, in the first direction, the distance between two adjacent fifth sub-pixel opening regions is less than the distance between two adjacent first sub-pixel opening regions, and the distance between two adjacent fifth sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions.

[0241] In some embodiments, for adjacent fourth and fifth pixels with the same grayscale, in a first direction, the distance between two adjacent fourth sub-pixel opening regions is equal to the distance between two adjacent fifth sub-pixel opening regions; in a second direction, the distance between adjacent fourth and fifth sub-pixel opening regions is equal to the distance between two adjacent fourth sub-pixel opening regions, the distance between adjacent fourth and fifth sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions, and the distance between adjacent fourth and fifth sub-pixel opening regions is greater than the distance between two adjacent first sub-pixel opening regions.

[0242] In some embodiments, when a third pixel group includes multiple fifth pixels with different gray levels, for multiple fifth pixels with sequentially increasing gray levels, in a first direction, the distance between the opening regions of two adjacent fifth sub-pixels of different fifth pixels decreases sequentially, and in a second direction, the distance between the opening regions of two adjacent fifth sub-pixels decreases sequentially.

[0243] In some embodiments, for adjacent fifth and second pixels in the second direction, in the first direction, the distance between two adjacent fifth sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions; and in the second direction, the distance between adjacent fifth and second sub-pixel opening regions is greater than the distance between two adjacent second sub-pixel opening regions.

[0244] In some embodiments, in a first direction, the distance between two adjacent sixth sub-pixel opening regions is equal to the distance between two adjacent second sub-pixel opening regions, and in a second direction, the distance between two adjacent sixth sub-pixel opening regions is equal to the distance between two adjacent second sub-pixel opening regions.

[0245] In practical implementation, multiple sub-pixel opening regions are divided into multiple sub-pixel opening rows and multiple sub-pixel opening columns. Each sub-pixel opening row includes multiple sub-pixel opening regions arranged along a first direction, and each sub-pixel opening column includes multiple sub-pixel opening regions arranged along a second direction. In each sub-pixel opening row, the center line connecting the centers of the corresponding complete rectangular opening regions of the sub-pixel opening regions is a straight line, and this straight line is parallel to the first direction. In each sub-pixel opening column, the center line connecting the centers of the corresponding complete rectangular opening regions of the sub-pixel opening regions is a straight line, and this straight line is parallel to the second direction. That is, even if the areas of the sub-pixel opening regions corresponding to different pixels are different, by adjusting the distance between the sub-pixel opening regions, i.e., the width of the second light-blocking part, it is possible to ensure that the lines connecting the corresponding rectangular opening regions of the sub-pixel opening regions in a row of sub-pixel opening regions in the first direction and a column of sub-pixel opening regions in the second direction are on a straight line. This alleviates color stripes and edge jaggedness while improving display uniformity and enhancing the display effect.

[0246] It should be noted that for the second and third pixels, the complete rectangular opening areas corresponding to the sub-pixel opening areas are the second sub-pixel opening area and the third sub-pixel opening area, respectively. For the first, fourth, and sixth pixels, parts of the first, fourth, and sixth sub-pixel opening areas are rectangular sub-pixel opening areas, while the remaining parts are non-rectangular sub-pixel opening areas. The complete rectangular opening areas corresponding to the non-rectangular sub-pixel opening areas are the rectangular first, fourth, and sixth sub-pixel opening areas.

[0247] It should be noted that, Figures 3-6 , Figures 8-12 The examples used here all assume a circular display area surrounded by a non-display area. In practice, the display area and non-display area can also be other shapes.

[0248] In some embodiments, it can also be as follows Figure 15 As shown, at least one non-display area 2 includes: a second non-display area 22 surrounded by display area 1; the second non-display area 22 is circular in shape, and the curved portion includes the circumference corresponding to the boundary between the second non-display area 22 and display area 1.

[0249] In some embodiments, such as Figure 16 As shown, the light-shielding layer 14 further includes a third light-shielding portion 23 and a first opening area 47 surrounded by the third light-shielding portion 23; the orthographic projection of the third light-shielding portion 23 and the first opening area 47 on the first substrate coincides with the second non-display area. In a specific implementation, the second non-display area may, for example, be equipped with a device such as a camera. The device such as the camera may be disposed, for example, in the first opening area.

[0250] It should be noted that, Figure 16 for Figure 15 A magnified diagram of region D in the middle.

[0251] It should be noted that, Figure 3 , Figure 15 The examples used here are all based on the boundary between one of the non-display areas and the display area as a circle. In specific implementations, the pattern formed by the boundary between the non-display area and the display area, including the curved portion, can also be other shapes. As long as the boundary between the non-display area and the display area includes a first arc portion and a second arc portion with equal curvature, it can be set such that at least one first sub-pixel opening area in the first pixel is adjacent to the first arc portion or the second arc portion.

[0252] It should be noted that, Figures 4-6 , Figures 8-12 Examples are given using the following conditions: the width in the second direction Y, adjacent sub-pixels with the same color in the first direction X, and adjacent sub-pixels with different colors in the second direction Y. Of course, other sub-pixel arrangements can be used in actual implementation.

[0253] In some embodiments, such as Figure 17 , Figure 18 As shown, in display area 1, any two adjacent sub-pixels 7 have different colors;

[0254] The graphic enclosed by the boundary between the non-display area 2 and the display area 1 has a first axis of symmetry 17 parallel to the first direction X and a second axis of symmetry 18 parallel to the second direction Y;

[0255] At least one arc includes a third arc portion 25 and a fourth arc portion 26 with equal curvature; the third arc portion 25 and the fourth arc portion 26 are respectively adjacent to the first axis of symmetry 17 on both sides of the first axis of symmetry 17, and the third arc portion 25 and the fourth arc portion 26 are centrally symmetrical.

[0256] At least one first sub-pixel opening region 8 in the first pixel 5 is adjacent to the third arc portion 25 or the fourth arc portion 26.

[0257] It should be noted that, Figure 18 for Figure 17 A magnified view of region E in the middle.

[0258] In practical implementation, when the first direction is horizontal, the third arc portion is located above the first axis of symmetry, and the third arc portion is located below the first axis of symmetry.

[0259] In some embodiments, the curvature of both the third and fourth arc portions is 30°.

[0260] It should be noted that when the width of a sub-pixel in the first direction X is smaller than its width in the second direction Y, and any two adjacent sub-pixels have different colors, the colored stripes mainly appear in the areas corresponding to the first and second arc portions with an arc of 30°. In the display panel provided in this embodiment, the third and fourth arc portions overlap with the first pixel, thus reducing the area of ​​the sub-pixel opening in the display area of ​​the first pixel adjacent to the third or fourth arc portion. This reduces the difference in the opening area between the sub-pixels in the first pixel corresponding to the third and fourth arc portions. Furthermore, the aperture ratio of the sub-pixels in the first pixel group located between the first and second pixels is less than the second aperture ratio and not less than the first aperture ratio. This alleviates the display defects of colored stripes appearing in the areas corresponding to the third and fourth arc portions, while also reducing jagged edges, improving the display effect and enhancing the user experience.

[0261] It should be noted that, as Figure 18 As shown, in the second direction Y, a red sub-pixel R in a pixel is adjacent to a green sub-pixel G in its neighboring pixel. The green sub-pixel G in this pixel is adjacent to a blue sub-pixel B in its neighboring pixel. The blue sub-pixel B in this pixel is adjacent to a red sub-pixel R in its neighboring pixel. Of course, the sub-pixels can be arranged in other orders, as long as any two adjacent sub-pixels are of different colors.

[0262] It should be noted that, Figure 18 Taking an example where the non-display area includes a first non-display area surrounding the display area, and the boundary between the first non-display area and the display area includes a third arc portion and a fourth arc portion. In a specific implementation, when the non-display area includes a second non-display area surrounded by the display area, and the boundary between the second non-display area and the display area includes a third arc portion and a fourth arc portion, at least one first sub-pixel opening area in the first pixel is adjacent to the third arc portion or the fourth arc portion of the display area near the second non-display area.

[0263] It should be noted that, Figure 18 Let's take the boundary between one of the non-display areas and the display area as a circle as an example. In specific implementations, the pattern formed by the boundary between the non-display area and the display area, including the curved portion, can also be other shapes. When any two adjacent sub-pixels have different colors, as long as the boundary between the non-display area and the display area includes a third arc portion and a fourth arc portion, it can be set such that at least one opening area of ​​the first sub-pixel in the first pixel is adjacent to the third arc portion or the fourth arc portion.

[0264] It should be noted that, Figures 1-6 , Figures 8-12 , Figure 17 , Figure 18The example given is a circle enclosed by the first non-display area. Of course, the shape enclosed by the first non-display area can also be other shapes.

[0265] In some embodiments, such as Figure 15 , Figure 19 As shown, the shape enclosed by the first non-display area 12 is a rounded rectangle. The curved portion 3 includes four rounded corner portions 27 at the boundary between the display area 1 and the first non-display area 12.

[0266] In specific implementation, such as Figure 15 As shown, the overall shape of display area 1 and the second non-display area 22 is a rounded rectangle. Figure 19 As shown, the shape of display area 1 is a rounded rectangle.

[0267] Next Figure 19 The display panel shown is used as an example for illustration. In some embodiments, such as... Figure 19 As shown, the boundary between the first non-display area 12 and the display area 1 also includes a first straight line portion 28 parallel to the second direction Y, and the two ends of the first straight line portion 28 are respectively connected to the rounded corner portion 27; the arc of the rounded corner portion 27 is less than or equal to 90° and greater than 60°;

[0268] Each rounded corner 27 is divided into: a first part 29 and a second part 30; the first part has an arc of 60°, and the second part 30 is connected to the first straight part 28;

[0269] In a specific implementation, at least one first sub-pixel opening region in the first pixel is adjacent to the second portion. When the multiple pixels also include a fourth pixel and a sixth pixel, the fourth pixel and the sixth pixel are adjacent to the first portion.

[0270] It should be noted that when the radius of the rounded corner is less than or equal to 90° and greater than 60°, the colored stripes mainly appear in the area corresponding to the second part.

[0271] The display panel provided in this embodiment has at least one first sub-pixel aperture area in the first pixel adjacent to the second part, which reduces the area of ​​the sub-pixel aperture area in the display area of ​​the first pixel adjacent to the second part. This reduces the difference between the aperture areas of each sub-pixel in the first pixel corresponding to the second part. Furthermore, the aperture ratio of the sub-pixels in the first pixel group located between the first pixel and the second pixel is less than the second aperture ratio and not less than the first aperture ratio. This can alleviate the display defects of color stripes appearing in the area corresponding to the second part, reduce the jaggedness, improve the display effect, and enhance the user experience.

[0272] It should be noted that, in practice, the display panel may consist of only one non-display area. For example, such as Figure 3 , Figure 17, Figure 19 As shown, non-display area 2 includes only the first non-display area 12. Alternatively, in a specific implementation, the display panel may include multiple non-display areas. For example, as... Figure 15 As shown, the plurality of non-display areas 2 include a first non-display area 12 and a second non-display area 22. In specific implementations, when the display panel includes a plurality of non-display areas, the boundary between one of the non-display areas and the display area may have a curved portion, or the boundary between each non-display area and the display area may have a curved portion.

[0273] It should be noted that, Figure 5 , Figure 6 , Figure 8 , Figure 10 , Figure 12 Let's take a circular shape surrounding the first display area as an example. When the display panel is a liquid crystal display panel, in specific implementation, regardless of whether the shape surrounding the first non-display area is circular or a rounded rectangle or other non-rectangular shape, the shape of the area surrounded by the first non-display area can be defined by the first light-shielding part.

[0274] In some embodiments, such as Figures 4-6 , Figures 8-12 , Figure 16 , Figure 18 As shown, the sub-pixels in the first pixel 5 correspond to only one first sub-pixel opening region 8.

[0275] Alternatively, in some embodiments, such as Figure 20 , Figure 21 As shown, at least some of the sub-pixels 7 in the first pixel 5 correspond to a plurality of first sub-pixel opening regions 8.

[0276] The display panel provided in this embodiment reduces the total opening area of ​​each sub-pixel in the display area by having at least some sub-pixels in the first pixel correspond to multiple sub-pixel opening areas. This reduces the difference between the opening areas corresponding to each sub-pixel in the first pixel, improves the uneven color mixing in the area corresponding to the curve at the boundary between the display area and the non-display area, alleviates the display defects of color stripes at the boundary between the display area and the non-display area, improves the display effect, and enhances the user experience.

[0277] It should be noted that, Figure 20 , Figure 21 Only a portion of the display panel is shown.

[0278] In practice, the size of the first sub-pixel opening area and the number of first sub-pixel opening areas corresponding to one sub-pixel can be set according to the actual sub-pixel size and process capability.

[0279] In some embodiments, such as Figure 20, Figure 21 As shown, multiple first sub-pixel opening regions 8 are arranged along the first direction X and / or the second direction Y.

[0280] Figure 20 The example is taken as one sub-pixel of the first pixel 5 corresponding to two first sub-pixel opening areas 8. One sub-pixel and two first sub-pixel opening areas are arranged along the second direction Y. Figure 21 The example is taken as one sub-pixel of the first pixel 5 corresponding to four first sub-pixel opening areas 8. One sub-pixel and four first sub-pixel opening areas 8 are arranged in two rows and two columns along the first direction X and the second direction Y.

[0281] In some embodiments, such as Figure 20 , Figure 21 As shown, each sub-pixel of the second pixel 9 corresponds to a second sub-pixel opening area 9.

[0282] This disclosure provides a display device, which includes a display panel provided in this disclosure.

[0283] In some embodiments, when the display panel is a liquid crystal display panel, the display device further includes a backlight module; the display panel is located on the light-emitting side of the backlight module.

[0284] The display device provided in this disclosure includes any product or component with a display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator. Other essential components of this display device are understood by those skilled in the art and will not be described in detail here, nor should they be construed as limiting this disclosure. Implementation of this display device can refer to the embodiments of the display panel described above; repeated details will not be repeated.

[0285] In summary, the display panel and display device provided in this disclosure have a non-rectangular shape for at least a portion of the opening area near the edge of the display area and the non-display area, thereby reducing the jaggedness at the boundary between the display area and the non-display area. The first aperture ratio is smaller than the second aperture ratio. Without changing the sub-pixel size, this is equivalent to reducing the opening area of ​​each sub-pixel in the first pixel within the display area, thus reducing the area of ​​the colored stripes. Furthermore, due to the reduced opening area, the sub-pixel brightness decreases, significantly improving the severity of the colored stripes. Moreover, with the first aperture ratio being smaller than the second aperture ratio, the aperture ratio of the sub-pixels in the first pixel group located between the first and second pixels is smaller than the second aperture ratio but not smaller than the first aperture ratio. This allows for a gradual transition in the aperture ratios of the first pixel, the third pixel, and the second pixel, avoiding large differences in brightness between adjacent pixels caused by excessive differences in aperture ratios. This avoids the jaggedness caused by large brightness differences, improving the display effect and enhancing the user experience.

[0286] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0287] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if these modifications and variations to the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and variations.
