Description

Technical Field

[0001] The present invention relates to the field of display technology, and in particular to a special-shaped display panel and a display device. Background Art

[0002] Irregular displays refer to displays with non-traditional regular shapes, which can be designed in any shape, size, and curvature to better suit specific scenarios or needs. This type of display is no longer limited to traditional rectangles or squares, but can be made into irregular shapes such as C-shaped and wavy shapes according to design requirements, and can even present oversized and curved designs. Irregular displays can achieve functions such as collaborative display and distributed display through multiple media playback devices. Due to its non-traditional appearance design and richer and more diverse visual experience, irregular displays are also widely used in advertising, activities, art and other fields. Compared with traditional displays, irregular displays have good visual effects, are adaptable to a wide range of scenarios, are more likely to attract attention, and have a larger viewing area, allowing users to have a better viewing experience.

[0003] However, pixels at the irregular boundary of the irregular display are blocked and cannot display all sub-pixels. Therefore, the display of the regular display area and the irregular display area is inconsistent, thereby affecting the overall display effect of the display panel. Summary of the Invention

[0004] The main purpose of the present invention is to provide a special-shaped display panel and a display device to solve the problem of uneven display of special-shaped display panels in the prior art.

[0005] To achieve the above objective, according to one aspect of the present invention, a special-shaped display panel is provided, comprising: special-shaped pixels and regular pixels, wherein the regular pixels are located in a regular display area, the special-shaped pixels are located in the special-shaped display area, the display area includes a special-shaped display area and a regular display area, the display area has a non-linear boundary, the special-shaped display area is adjacent to the non-linear boundary, and the non-display area surrounds the display area; an opening area of ​​the special-shaped pixels is smaller than an opening area of ​​the regular pixels; each of the special-shaped pixels includes at least one special-shaped sub-pixel; each of the regular pixels includes at least three regular sub-pixels; any two of the regular sub-pixels have different colors; the type of color of the regular sub-pixels is the same as the type of color of the special-shaped sub-pixels in the special-shaped display area; in at least two adjacent special-shaped pixels, the sum of the opening areas of the special-shaped sub-pixels of the same color is a first area; in the regular display area, the sum of the opening areas of the regular sub-pixels of the same color is a second area; a ratio between the first areas of different colors is a first ratio; a ratio between the second areas of different colors is a second ratio; and the first ratio is equal to the second ratio.

[0006] Furthermore, the arrangement order of the irregular-shaped sub-pixels in at least two of the irregular-shaped pixels is different.

[0007] Furthermore, at least one of the irregularly shaped pixels includes at least two irregularly shaped sub-pixels, and in some of the irregularly shaped pixels among the plurality of irregularly shaped pixels, two adjacent irregularly shaped sub-pixels in two adjacent irregularly shaped pixels have the same color.

[0008] Furthermore, each of the irregularly shaped pixels includes at least two irregularly shaped sub-pixels, and in some of the irregularly shaped pixels among the plurality of irregularly shaped pixels, the arrangement order of the irregularly shaped sub-pixels in two adjacent irregularly shaped pixels is opposite.

[0009] Furthermore, among some of the plurality of the irregular pixels, two adjacent irregular pixels are a first adjacent pixel and a second adjacent pixel, the first adjacent pixel has one less irregular sub-pixel of a predetermined color than the second adjacent pixel, and the color of the irregular sub-pixel adjacent to the first adjacent pixel in the second adjacent pixel is the predetermined color.

[0010] Furthermore, the colors of the irregular-shaped sub-pixels include at least three of red, blue, green and white.

[0011] Furthermore, there are three types of colors of the irregular-shaped sub-pixels, and the first ratio is a:b:c, wherein at least two of a, b and c are equal.

[0012] Furthermore, the colors of the irregular sub-pixels include red, green and blue, and the first ratio is a:b:c, wherein a is the first area corresponding to the red, b is the first area corresponding to the green, and c is the first area corresponding to the blue, c is smaller than b, and c is smaller than a.

[0013] Furthermore, when the area of ​​the irregular-shaped display region is smaller than or equal to a first area threshold, the portion of the irregular-shaped pixel located in the irregular-shaped display region includes one irregular-shaped sub-pixel.

[0014] Furthermore, when the area of ​​the irregular display region is greater than a first area threshold and less than or equal to a second area threshold, the irregular pixel includes two irregular sub-pixels, and the first area threshold is less than the second area threshold.

[0015] Furthermore, when the area of ​​the irregular display region is greater than a second area threshold and less than or equal to a third area threshold, the irregular pixel includes three irregular sub-pixels, and the second area threshold is less than the third area threshold.

[0016] Furthermore, the irregular display area has a non-linear boundary, and in each of the irregular sub-pixels, an opening boundary of the irregular sub-pixel close to the non-linear boundary is parallel to a tangent direction of the non-linear boundary.

[0019] The technical solution of the present invention provides a special-shaped display panel. Distinctive-shaped pixels are arranged within a special-shaped display area near a non-linear boundary. This allows normal display even in the special-shaped boundary area, alleviating the problem of jagged edges. Furthermore, because the ratio between the different-colored special-shaped sub-pixels in the special-shaped display area is the same as the ratio between the different-colored special-shaped sub-pixels in the regular display area, the display effect in the special-shaped display area can be made closer to that in the regular display area. This reduces the display differences and color shift caused by the occlusion of the special-shaped pixels by the special-shaped boundary, thereby improving the display quality of the display panel.

[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] It should be noted that the terms "first," "second," and the like in the specification and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate for the embodiments of the present invention described herein. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to these processes, methods, products, or apparatuses.

[0036] As described in the background art, the irregular display panels in the prior art display unevenness. In order to solve the above technical problems, the present application proposes an irregular display panel and a display device.

[0037] Figure 1 Schematic diagram of the structure of the special-shaped display panel according to the embodiment of the present application. Figures 1 to 4 As shown, the display area 10 includes: a special-shaped pixel 30 and a regular pixel 40. The difference between the special-shaped pixel 30 and the regular pixel 40 lies in the location and size of the opening. The regular pixel 40 is located in the regular display area 101, and the special-shaped pixel 30 is located in the special-shaped display area 102. In other words, the display area 10 includes the regular display area 101 and the special-shaped display area 102. The display area 10 has a non-linear boundary, which can be an arc, a curve, or an irregular shape composed of curved and straight segments. The special-shaped display area 102 is adjacent to the non-linear boundary. This application does not limit the area of ​​the special-shaped display area 102. The non-display area 20 surrounds the display area 10. The opening area of ​​the special-shaped pixel 30 is smaller than the opening area of ​​the regular pixel 40. The opening area of ​​the special-shaped pixel 30 is the sum of the areas of its various special-shaped sub-pixels 301. Similarly, the opening area of ​​the regular pixel 40 is the sum of the areas of its various regular sub-pixels 401. Each of the above-mentioned irregular-shaped pixels 30 includes at least one irregular-shaped sub-pixel 301, such as Figure 2 As shown, the irregular pixel 30 in the figure may include one irregular sub-pixel 301, two irregular sub-pixels 301, or three irregular sub-pixels 301, depending on the position of the irregular pixel 30 in the irregular display area 102. Each of the above-mentioned regular pixels 40 includes at least three regular sub-pixels 401, and the colors of any two of the above-mentioned regular sub-pixels 401 are different. The opening shapes of the above-mentioned irregular sub-pixels 301 and the above-mentioned regular sub-pixels 401 are not limited to Figure 2The rectangle in the image may be any other shape, and the opening shapes of the irregular sub-pixel 301 and the regular sub-pixel 401 may be the same or different. The color of the regular sub-pixel 401 is the same as the color of the irregular sub-pixel 301 in the irregular display area 102. That is, when the color of the regular sub-pixel 401 is one of the three colors of red, green, and blue (RGB), the color of the irregular sub-pixel 301 is also one of the three colors of red, green, and blue (RGB). In at least two adjacent irregular pixels 30, the sum of the opening areas of the irregular sub-pixels 301 of the same color is a first area, and in the regular display area 101, the sum of the opening areas of the regular sub-pixels 401 of the same color is a second area. The ratio between the first areas of different colors is a first ratio, and the ratio between the second areas of different colors is a second ratio, and the first ratio is equal to the second ratio. Specifically, the adjacent irregular-shaped pixels 30 mentioned above refer to two irregular-shaped pixels 30 that are adjacent in a predetermined direction, wherein the predetermined direction is perpendicular to the thickness direction of the irregular-shaped display panel.

[0038] like Figure 3 As shown, each of the above-mentioned special-shaped pixels 30 includes three special-shaped sub-pixels 301, and each of the regular pixels 40 includes three regular sub-pixels 401. Figure 3 (For example, the two irregular pixels in the dashed box in the figure are RGB types of regular sub-pixel 401 and irregular sub-pixel 301. For example, in two adjacent irregular pixels 30, the first area of ​​R is x, the first area of ​​G is y, and the first area of ​​B is z. In the regular pixel 40, the second area of ​​R is i, the second area of ​​G is j, and the second area of ​​B is k. The first ratio is x:y:z, and the second ratio is i:j:k, where x:y:z=i:j:k. In another specific embodiment, x:y:z=i:j:k=1:1:1. It should be noted that Figure 3 The colors of the sub-pixels with the same filling pattern are the same. Figure 4 As shown, some of the above-mentioned irregular pixels 30 include three irregular sub-pixels 301, some of the above-mentioned irregular pixels 30 include two irregular sub-pixels 301, and each regular pixel 40 includes three regular sub-pixels 401. Similarly, in two adjacent irregular pixels 30, the first area of ​​R is x, the first area of ​​G is y, and the first area of ​​B is z; in the regular pixel 40, the second area of ​​R is i, the second area of ​​G is j, and the second area of ​​B is k. The first ratio is x:y:z, and the second ratio is i:j:k, where x:y:z = i:j:k. In another specific embodiment, x:y:z = i:j:k = 1:1:1.

[0039] It should be noted that the above Figure 3In the embodiment of the present invention, two adjacent irregularly shaped pixels 30 are used as an example. In the two adjacent irregularly shaped pixels, the first ratio and the second ratio are equal. In other optional embodiments, the first ratio and the second ratio may be equal in three adjacent irregularly shaped pixels; or the first ratio and the second ratio may be equal in more than three adjacent irregularly shaped pixels. This patent does not limit this.

[0040] In the embodiments of the present application, the special-shaped display panel, by disposing special-shaped pixels within the special-shaped display area near the non-linear boundary, allows normal display even in the special-shaped boundary area, thus alleviating the problem of jagged edges on the special-shaped edges. Furthermore, because the ratio between the different-colored special-shaped sub-pixels in the special-shaped display area is the same as the ratio between the different-colored special-shaped sub-pixels in the regular display area, the display effect in the special-shaped display area can be made closer to that in the regular display area. This reduces the display differences and color shift caused by the occlusion of the special-shaped pixels by the special-shaped boundary, thereby improving the display quality of the display panel.

[0041] In some embodiments, as Figure 2 As shown, the arrangement order of the irregular sub-pixels 301 in at least two irregular pixels 30 is different. Furthermore, the arrangement order of the irregular sub-pixels 301 in the irregular pixel 30 can be the same as or different from the arrangement order of the regular sub-pixels 401 in the regular pixel 40. By adjusting the arrangement order of the irregular sub-pixels 301 in the irregular pixel 30, the display difference between the irregular pixel 30 and the regular pixel 40 caused by the irregular boundary can be further compensated.

[0042] Specifically, if Figure 3 As shown, taking the three types of irregular sub-pixels 301, RGB, as an example, the arrangement order of the irregular sub-pixels 301 can be R—G—B, B—G—R, G—R—B, R—B—G, B—R—G, and G—R—B. The arrangement order of some of the irregular sub-pixels 301 is the same as the arrangement direction of the regular sub-pixels 401. The arrangement order of some of the irregular sub-pixels 301 is different from the arrangement direction of the regular sub-pixels 401. In another specific embodiment, when comparing the arrangement order of the irregular sub-pixels 301 in two irregular pixels 30, the number of irregular sub-pixels 301 in the two irregular pixels 30 is the same, for example, the number of irregular sub-pixels 301 in both irregular pixels 30 is three.

[0043] In some further embodiments, Figure 5As shown, at least one of the above-mentioned irregularly shaped pixels 30 includes at least two of the above-mentioned irregularly shaped sub-pixels 301. In some of the above-mentioned irregularly shaped pixels 30, the two adjacent irregularly shaped sub-pixels 301 in the plurality of the above-mentioned irregularly shaped pixels 30 have the same color. In the irregular display area near the non-linear boundary, the aperture area of ​​the irregularly shaped sub-pixels 301 tends to gradually increase or decrease. In other words, in the two adjacent irregularly shaped sub-pixels 301 in the two adjacent irregularly shaped pixels 30, the aperture area of ​​one irregularly shaped sub-pixel 301 is the maximum value in the one irregularly shaped pixel 30, and the aperture area of ​​the other irregularly shaped sub-pixel 301 is the minimum value in the other irregularly shaped pixel 30. Therefore, the two adjacent irregularly shaped sub-pixels 301 have the same color. The irregularly shaped sub-pixel 301 with the larger aperture area can compensate for the irregularly shaped sub-pixel 301 with the smaller aperture area, reducing the brightness difference caused by the smaller aperture area, thereby further improving the display effect of the irregularly shaped display area.

[0044] Specifically, the number of shaped sub-pixels in two adjacent shaped pixels may be the same or different. For example, the number of shaped sub-pixels in one shaped pixel is two, and the number of shaped sub-pixels in another shaped pixel is three, as long as the colors of the two adjacent shaped sub-pixels are the same. This application does not limit the arrangement of the remaining shaped sub-pixels in the shaped pixel. The arrangement order of the remaining two shaped sub-pixels in two adjacent shaped pixels may be the same or different. It should be noted that the above Figure 5 Only two special-shaped pixels and their included special-shaped sub-pixels in the special-shaped display area are shown. In fact, the special-shaped display area also includes other special-shaped pixels that are not shown.

[0045] In another specific embodiment, Figure 6 As shown, each of the aforementioned irregular pixels 30 includes at least two of the aforementioned irregular sub-pixels 301. In some of the aforementioned irregular pixels 30 among the plurality of the aforementioned irregular pixels 30, the arrangement order of the aforementioned irregular sub-pixels 301 in two adjacent irregular pixels 30 is opposite. In the two adjacent irregular pixels 30, the variation trend of the aperture area of ​​the irregular sub-pixels 301 is the same. Therefore, the arrangement order of the aforementioned irregular sub-pixels 301 in two adjacent irregular pixels 30 is opposite. The irregular sub-pixels 301 of the same color can compensate for the irregular sub-pixels 301 in the adjacent irregular pixels 30, reducing the brightness difference caused by the smaller aperture area, thereby further improving the display effect of the irregular display area.

[0046] Specifically, taking the three types of irregular-shaped sub-pixels, RGB, as an example, the arrangement order of two adjacent irregular-shaped pixels can be R—G—B and B—G—R, G—R—B and B—R—G, R—B—G and G—B—R. Figure 6 Only two special-shaped pixels and their included special-shaped sub-pixels in the special-shaped display area are shown. In fact, the special-shaped display area also includes other special-shaped pixels that are not shown.

[0047] In some further embodiments, Figure 7 As shown, among some of the plurality of irregular pixels, two adjacent irregular pixels are a first adjacent pixel 50 and a second adjacent pixel 51. The first adjacent pixel 50 has one less irregular sub-pixel 301 of a predetermined color than the second adjacent pixel 51. The color of the irregular sub-pixel 301 adjacent to the first adjacent pixel 50 in the second adjacent pixel 51 is the predetermined color. In the display panel manufacturing process, due to process limitations, the pixel opening cannot be infinitely small. In other words, if the pixel opening is too small, the pixel opening setting, i.e., the irregular sub-pixel 301 of the predetermined color missing from the first adjacent pixel 50, cannot be achieved. In this case, color shift may occur in the display effect. By compensating the first adjacent pixel with the irregular sub-pixel of the predetermined color in the second adjacent pixel, the risk of color shift caused by the lack of the predetermined color can be reduced, thereby further improving the display effect of the irregular display area.

[0048] Specifically, Figure 7 In the example above, the first adjacent pixel includes two irregular sub-pixels and the second adjacent pixel includes three irregular sub-pixels. In fact, the first adjacent pixel may include one irregular sub-pixel and the second adjacent pixel may include two irregular sub-pixels. Figure 7 Only the first adjacent pixel and the second adjacent pixel in the irregular display area and the irregular sub-pixels included therein are shown. In fact, the irregular display area also includes other irregular pixels which are not shown.

[0049] In some embodiments, the colors of the irregular sub-pixels include at least three of red, blue, green, and white. The combination of the color resists of the above multiple colors can produce multiple colors, thereby further realizing a colorful image on the display panel.

[0050] Specifically, in the above embodiments, the regular sub-pixels 401 include sub-pixels for the three primary colors of red (R), green (G), and blue (B). Each color sub-pixel is responsible for processing a color channel, and by adjusting the intensity of each sub-pixel, multiple colors can be combined to produce. In some other optional embodiments, the regular sub-pixels also include a white (W) sub-pixel.

[0051] In some further embodiments, the irregularly shaped sub-pixels have three colors, and the first ratio is a:b:c, where at least two of a, b, and c are equal. This arrangement can further reduce the total number of irregularly shaped sub-pixels within the irregularly shaped display area while maintaining the same display resolution and similar display effects as a conventional sub-pixel strip arrangement.

[0052] In another specific embodiment, a=b=c. The above setting can ensure uniform display of each color, further avoid color deviation or unevenness caused by too many or too few sub-pixels of a certain color, and can also simplify the manufacturing process and further improve production yield.

[0053] In another specific embodiment, the colors of the irregularly shaped sub-pixels include red, green, and blue, and the first ratio is a:b:c, where a is the first area corresponding to the red color, b is the first area corresponding to the green color, and c is the first area corresponding to the blue color, with c being smaller than b, and c being smaller than a. Because blue sub-pixels have lower luminous efficiency and a shorter lifespan, reducing the first area corresponding to the blue sub-pixels in the irregularly shaped sub-pixels can reduce loss of blue luminescent material, thereby further extending the overall lifespan of the display device and reducing energy consumption of the display panel.

[0054] In practical applications, the higher energy of blue light photons easily causes the decay of blue light materials, resulting in a luminous efficiency far lower than that of red and green light materials. This means that to achieve the same brightness as red and green light, blue light requires a higher current, which accelerates the decay of the blue light material and affects the lifespan and color accuracy of the screen. In addition, the human eye has different sensitivities to different colors. According to the photopic curve, green is the color most easily perceived and captured by the human eye, while the human eye has a weaker response to red and violet at the edge of the spectrum. Therefore, in display technology, the number of green sub-pixels is usually maintained, while the number of red and blue sub-pixels is reduced to balance the lifespan and display quality of the three sub-pixels. Therefore, compared with the red and green color resists, the blue color resist contributes relatively less to the visual effect, so the first area corresponding to the blue in the special-shaped sub-pixel can be reduced accordingly.

[0055] In some other embodiments, Figure 8 As shown, the first predetermined pixel 70 is a special-shaped pixel. When the area of ​​the special-shaped display region is less than or equal to the first area threshold, the portion of the special-shaped pixel located within the special-shaped display region includes one special-shaped sub-pixel 301. By accurately setting the number of special-shaped sub-pixels 301 in a special-shaped pixel, the cost of the special-shaped sub-pixels 301 can be reduced, thereby further reducing the production cost of the special-shaped display surface.

[0056] In actual applications, due to limitations in the manufacturing process, the opening of the irregular-shaped sub-pixel will not be infinitely small. If the area of ​​the irregular-shaped pixel in the irregular-shaped display area is smaller than the minimum opening allowed by the process, the opening may be omitted. If the area of ​​the irregular-shaped pixel in the irregular-shaped display area is greater than or equal to the minimum opening allowed by the process and less than or equal to the first area threshold, the irregular-shaped pixel located in the irregular-shaped display area includes only one irregular-shaped sub-pixel. The opening size of the one irregular-shaped sub-pixel can be smaller than the size of the irregular-shaped sub-pixel, or it can be the same size as the irregular-shaped sub-pixel.

[0057] In some embodiments, as Figure 8 As shown, the second predetermined pixel 71 is a special-shaped pixel. When the area of ​​the special-shaped display region is greater than a first area threshold and less than or equal to a second area threshold, the special-shaped pixel includes two special-shaped sub-pixels 301, and the first area threshold is less than the second area threshold. By accurately setting the number of special-shaped sub-pixels 301 in a special-shaped pixel, the cost of the special-shaped sub-pixels 301 can be reduced, thereby further reducing the production cost of the special-shaped display surface.

[0058] Specifically, the opening size of any one of the two irregular-shaped sub-pixels may be smaller than that of the irregular-shaped sub-pixel, or may be the same as that of the irregular-shaped sub-pixel. In another embodiment, when the boundary of the irregular-shaped display area intersects with the irregular-shaped sub-pixel located in the middle of the irregular-shaped pixel and does not intersect with the irregular-shaped sub-pixel near the irregular-shaped boundary, the irregular-shaped pixel located in the irregular-shaped display area includes the two irregular-shaped sub-pixels.

[0059] In some further embodiments, Figure 8 As shown, the third predetermined pixel 72 is a special-shaped pixel. When the area of ​​the special-shaped display area is greater than the second area threshold and less than or equal to the third area threshold, the special-shaped pixel includes three special-shaped sub-pixels 301, and the second area threshold is less than the third area threshold. By accurately setting the number of special-shaped sub-pixels 301 in a special-shaped pixel, the cost of the special-shaped sub-pixels 301 can be reduced, thereby further reducing the production cost of the special-shaped display surface.

[0060] Specifically, the opening size of the irregular-shaped sub-pixel in the three irregular-shaped sub-pixels can be smaller than the size of the irregular-shaped sub-pixel, or can be the same size as the irregular-shaped sub-pixel, but at least one irregular-shaped sub-pixel has an opening smaller than the size of the irregular-shaped sub-pixel. In another embodiment, when the boundary of the irregular-shaped display area intersects with the irregular-shaped sub-pixel near the irregular-shaped boundary, the irregular-shaped pixel located in the irregular-shaped display area includes three of the irregular-shaped sub-pixels.

[0061] In another specific embodiment, the irregular display area has a non-linear boundary, and in each of the irregular sub-pixels, the opening boundary of the irregular sub-pixel near the non-linear boundary is parallel to a tangent line of the non-linear boundary. This arrangement allows the irregular sub-pixel to conform to the irregular boundary, reduces jagged grayscale transitions in the irregular display area, and further improves the display quality of the display panel.

[0062] In practical applications, the opening boundary of the above-mentioned irregularly shaped sub-pixel can be the same as the non-linear boundary, or can be parallel to the tangent line of the non-linear boundary.

[0063] In some further embodiments, Figure 9 As shown, the above-mentioned special-shaped display panel also includes an array substrate 81 and a color filter substrate 80 stacked in sequence. The special-shaped display panel also includes a liquid crystal layer 82 located between the array substrate 81 and the color filter substrate 80. The array substrate 81 includes pixel electrodes, common electrodes, and thin-film transistors arranged in an array. The thin-film transistors are used to drive the above-mentioned special-shaped sub-pixels and the above-mentioned regular sub-pixels. The above-mentioned sub-pixels are either the above-mentioned regular sub-pixels or the above-mentioned special-shaped sub-pixels. The above-mentioned color filter substrate 80 includes a black matrix layer and a color resist layer. The above-mentioned black matrix layer includes multiple black matrices with intervals. The above-mentioned sub-pixels are located in the intervals between two adjacent black matrices. The above-mentioned structural arrangement can further realize image display of the special-shaped display panel.

[0064] Specifically, an electric field that controls the deflection of liquid crystal molecules can be formed between the pixel electrode and the common electrode. Light passes through the array substrate and irradiates the liquid crystal molecule layer. After being deflected by the liquid crystal molecules, it is emitted to the color filter substrate. Then, after passing through the color resists of various colors on the color filter substrate, it can be emitted as light of multiple colors on the display panel surface, ultimately forming a pattern display on the display panel surface. In another typical embodiment of the present application, if Figure 10 As shown, a display device is provided, including: any one of the above-mentioned special-shaped display panels 60.

[0065] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0066] 1) The special-shaped display panel of the present application sets special-shaped pixels in the special-shaped display area near the non-linear boundary, which allows the special-shaped boundary area to display normally, improving the problem of jagged edges on the special-shaped edges. In addition, because the ratio between the different-colored special-shaped sub-pixels in the special-shaped display area is the same as the ratio between the different-colored special-shaped sub-pixels in the regular display area, the display effect in the special-shaped display area can be made closer to that in the regular display area, reducing the display difference and color shift caused by the occlusion of the special-shaped pixels by the special-shaped boundary, thereby improving the display effect of the display panel.

[0067] 2) The display device of the present application includes the aforementioned special-shaped display panel. Distinctive-shaped pixels are provided within the special-shaped display area near the non-linear boundary. This allows the special-shaped boundary area to display normally, thereby improving the problem of jagged edges on the special-shaped edges. Furthermore, because the ratio between the different-colored special-shaped sub-pixels in the special-shaped display area is the same as the ratio between the different-colored special-shaped sub-pixels in the regular display area, the display effect in the special-shaped display area can be made closer to that in the regular display area. This reduces the display difference and color shift caused by the occlusion of the special-shaped pixels by the special-shaped boundary, thereby improving the display effect of the display device.

[0068] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
