[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme 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 described embodiments 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 creative work should fall within the scope of protection of the present invention.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] As introduced in the background technology, the special-shaped display panel in the prior art has uneven display. In order to solve the above technical problems, the present application proposes a special-shaped display panel and a display device.

[0037] Figure 1 is a schematic diagram of the structure of a special-shaped display panel according to an embodiment of the present application. Figures 1 to 4 As shown, it 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 position and the 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. That is to say, the display area 10 includes the regular display area 101 and the special-shaped display area 102. The display area 10 has a non-straight line boundary, which can be an arc, a curve, or an irregular shape composed of a curve segment and a straight line segment. The special-shaped display area 102 is adjacent to the non-straight line boundary. The 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 the special-shaped sub-pixels 301 it has. Similarly, the opening area of ​​the regular pixel 40 is the sum of the areas of the regular sub-pixels 401 it has. Each of the above-mentioned irregular pixel 30 includes at least one irregular 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 above-mentioned special-shaped sub-pixel 301 may be any other shape, and the opening shapes of the above-mentioned special-shaped sub-pixel 301 and the above-mentioned regular sub-pixel 401 may be the same or different. The type of color of the above-mentioned regular sub-pixel 401 is the same as the type of color of the above-mentioned special-shaped sub-pixel 301 in the above-mentioned special-shaped 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 special-shaped sub-pixel 301 is also one of the three colors of red, green and blue (RGB). In at least two adjacent special-shaped pixels 30, the sum of the opening areas of the above-mentioned special-shaped sub-pixels 301 of the same color is a first area, and in the above-mentioned regular display area 101, the sum of the opening areas of the above-mentioned regular sub-pixels 401 of the same color is a second area, the ratio between the above-mentioned first areas of different colors is a first ratio, and the ratio between the above-mentioned second areas of different colors is a second ratio, and the above-mentioned first ratio is equal to the above-mentioned 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 irregular pixel 30 includes three irregular sub-pixels 301, each regular pixel 40 includes three regular sub-pixels 401, and the adjacent two irregular pixels ( Figure 3 In the example of the two special-shaped pixels in the dashed box in the figure, taking the type of the regular sub-pixel 401 and the special-shaped sub-pixel 301 as RGB, in the two adjacent special-shaped 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 first area of ​​R is i, the first area of ​​G is j, and the first area of ​​B is k, the first ratio is x:y:z, and the second ratio is l:j:k, 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 special-shaped pixels 30 include three special-shaped sub-pixels 301, some of the above-mentioned special-shaped pixels 30 include two special-shaped sub-pixels 301, and each regular pixel 40 includes three regular sub-pixels 401. Similarly, in two adjacent special-shaped 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 first area of ​​R is i, the first area of ​​G is j, and the first area of ​​B is k. The first ratio is x:y:z, and the second ratio is i:j:k, 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 3The implementation method of the embodiment takes two adjacent irregular pixels 30 as an example, in the two adjacent irregular pixels, the first ratio is equal to the second ratio. In other optional implementations, it can also be satisfied that in three adjacent irregular pixels, the first ratio is equal to the second ratio; or in more than three adjacent irregular pixels, the first ratio is equal to the second ratio, which is not limited by this patent.

[0040] In the embodiment of the present application, the shaped display panel is provided with shaped pixels in the shaped display area near the non-straight line boundary, so that the shaped boundary area can also be displayed normally, and the problem of aliasing of the shaped edge is improved. In addition, since the ratio between the shaped sub-pixels of different colors in the shaped display area is the same as the ratio between the shaped sub-pixels of different colors in the conventional display area, the display effect in the shaped display area can be made close to the display effect in the conventional display area, reducing the display difference and color deviation between the shaped display area and the conventional display area due to the occlusion of the shaped pixels by the shaped boundary, thereby improving the display effect of the display panel.

[0041] In some embodiments, Figure 2 As shown, the arrangement order of the above-mentioned shaped sub-pixels 301 in at least two of the above-mentioned shaped pixels 30 is different. In addition, the arrangement order of the above-mentioned shaped sub-pixels 301 in the shaped 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 shaped sub-pixels 301 in the shaped pixel 30, the display difference between the shaped pixel 30 and the regular pixel 40 caused by the shaped boundary can be further compensated.

[0042] Specifically, Figure 3 As shown, taking the three types of the irregular sub-pixels 301, RGB, as an example, the arrangement order of the irregular sub-pixels 301 may 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, in the comparison of the arrangement order of the irregular sub-pixels 301 in the two irregular pixels 30, the number of the irregular sub-pixels 301 in the two irregular pixels 30 is the same, for example, the number of the irregular sub-pixels 301 in the two irregular pixels 30 is three.

[0043] In some other embodiments, Figure 5As shown, at least one of the above-mentioned special-shaped pixels 30 includes at least two of the above-mentioned special-shaped sub-pixels 301, and in some of the above-mentioned special-shaped pixels 30 among the plurality of the above-mentioned special-shaped pixels 30, the colors of the two adjacent special-shaped sub-pixels 301 in the two adjacent special-shaped pixels 30 are the same. In the special-shaped display area close to the non-linear boundary, the opening area of ​​the special-shaped sub-pixel 301 tends to gradually increase or decrease. That is to say, in the two adjacent special-shaped sub-pixels 301 in the two adjacent special-shaped pixels 30, the opening area of ​​one special-shaped sub-pixel 301 is the maximum value in one special-shaped pixel 30, and the opening area of ​​the other special-shaped sub-pixel 301 is the minimum value in the other special-shaped pixel 30. Therefore, the colors of the two adjacent special-shaped sub-pixels 301 are the same, and the special-shaped sub-pixel 301 with a larger opening area can compensate for the special-shaped sub-pixel 301 with a smaller opening area, thereby reducing the difference in brightness caused by the smaller opening area, thereby further improving the display effect of the special-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. The present 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 irregular-shaped pixels and irregular-shaped sub-pixels included in the irregular-shaped display area are shown. In fact, the irregular-shaped display area also includes other irregular-shaped pixels which are not shown.

[0045] In another specific embodiment, Figure 6 As shown, each of the above-mentioned special-shaped pixels 30 includes at least two of the above-mentioned special-shaped sub-pixels 301, and in some of the above-mentioned special-shaped pixels 30 among the plurality of the above-mentioned special-shaped pixels 30, the arrangement order of each of the above-mentioned special-shaped sub-pixels 301 in two adjacent special-shaped pixels 30 is opposite. In the two adjacent special-shaped pixels 30, the change trend of the opening area of ​​the special-shaped sub-pixels 301 is the same. Therefore, the arrangement order of the above-mentioned special-shaped sub-pixels 301 in the two adjacent special-shaped pixels 30 is opposite, and the special-shaped sub-pixels 301 of the same color can compensate for the special-shaped sub-pixels 301 in the adjacent special-shaped pixels 30, reduce the difference in brightness caused by the small opening area, and further improve the display effect of the special-shaped display area.

[0046] Specifically, taking the three types of irregular sub-pixels, RGB, as an example, the arrangement order of two adjacent irregular sub-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 irregular-shaped pixels and irregular-shaped sub-pixels included in the irregular-shaped display area are shown. In fact, the irregular-shaped display area also includes other irregular-shaped pixels which are not shown.

[0047] In some other embodiments, Figure 7 As shown, among some of the above-mentioned special-shaped pixels among the plurality of the above-mentioned special-shaped pixels, two adjacent special-shaped pixels are a first adjacent pixel 50 and a second adjacent pixel 51, and the above-mentioned first adjacent pixel 50 has one less special-shaped sub-pixel 301 of a predetermined color than the above-mentioned second adjacent pixel 51, and the color of the special-shaped sub-pixel 301 adjacent to the above-mentioned first adjacent pixel 50 in the above-mentioned second adjacent pixel 51 is the above-mentioned predetermined color. In the manufacturing process of the display panel, due to the limitation of the process conditions, the opening of the pixel cannot meet the infinitesimal requirement, that is, when the opening of the pixel is too small, the opening setting of the pixel, i.e., the special-shaped sub-pixel 301 of the predetermined color missing in the first adjacent pixel 50, cannot be realized. In this case, the problem of color deviation may occur in the display effect. By compensating the first adjacent pixel with the special-shaped sub-pixel of the predetermined color in the second adjacent pixel, the risk of color deviation caused by the lack of the predetermined color can be reduced, thereby further improving the display effect of the special-shaped 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 above-mentioned irregular sub-pixels include at least three of red, blue, green and white. The color combination of the above-mentioned multiple colors of color resist can produce multiple colors, thereby further realizing the display of colorful images on the display panel.

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

[0051] In some further embodiments, the types of colors of the irregular sub-pixels are three, and the first ratio is a:b:c, wherein at least two of a, b and c are equal. The above arrangement can further reduce the total number of irregular sub-pixels in the irregular display area while maintaining the same display resolution and similar display effect as the 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 the production yield.

[0053] In another specific embodiment, the colors of the irregular sub-pixel 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, c is the first area corresponding to the blue, and c is smaller than b, and c is smaller than a. Since the blue sub-pixel has a lower luminous efficiency and a shorter lifespan, by reducing the first area corresponding to the blue sub-pixel in the irregular sub-pixel, the loss of the blue luminescent material can be reduced, thereby further extending the overall service life of the display device and reducing the energy consumption of the display panel.

[0054] In practical applications, due to the higher energy of blue light photons, it is easy to cause the decay of blue light materials, resulting in the luminous efficiency of blue light materials being much lower than that of red and green light materials. This means that in order to achieve the same brightness as red and green light, blue light requires a larger current, which accelerates the decay of blue light materials and affects the service life 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 that is most easily perceived and captured by the human eye, while the human eye reacts less to red and purple at the edge of the spectrum. Therefore, in display technology, the number of green sub-pixels usually remains unchanged, while the number of red and blue sub-pixels decreases to balance the lifespan and display effect of the three sub-pixels. Therefore, compared with red and green color resistance, the contribution of blue color resistance to visual effects is relatively small, 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 area is less than or equal to the first area threshold, the portion of the special-shaped pixel located in the special-shaped display area includes one special-shaped sub-pixel 301. By accurately setting the number of special-shaped sub-pixels 301 in one special-shaped pixel, the cost of the special-shaped sub-pixel 301 can be reduced, thereby further reducing the manufacturing cost of the special-shaped display surface.

[0056] In practical applications, due to the limitation of the manufacturing process, the opening of the irregular sub-pixel will not be infinitely small. When the area of ​​the irregular pixel in the irregular display area is smaller than the minimum opening allowed by the process, it can be chosen not to have an opening. When the area of ​​the irregular pixel in the irregular 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 pixel located in the irregular display area includes only one irregular sub-pixel. The opening size of the one irregular sub-pixel can be smaller than the size of the irregular sub-pixel, or can be the same as the size of the irregular sub-pixel.

[0057] In some embodiments, Figure 8 As shown, the second predetermined pixel 71 is a special-shaped pixel. When the area of ​​the special-shaped display area is greater than the first area threshold and less than or equal to the 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-pixel 301 can be reduced, thereby further reducing the manufacturing cost of the special-shaped display surface.

[0058] Specifically, the opening size of any one of the two irregular sub-pixels may be smaller than the size of the irregular sub-pixel, or may be the same as the size of the irregular sub-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-pixel 301 can be reduced, thereby further reducing the production cost of the special-shaped display surface.

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

[0061] In another specific embodiment, the above-mentioned special-shaped display area has a non-linear boundary, and in each of the above-mentioned special-shaped sub-pixels, the opening boundary of the above-mentioned special-shaped sub-pixel close to the above-mentioned non-linear boundary is parallel to the tangent direction of the above-mentioned non-linear boundary. The above-mentioned arrangement can make the special-shaped sub-pixel adapt to the special-shaped boundary, reduce the jagged unevenness of the grayscale transition in the special-shaped display area, and further improve the display effect of the display panel.

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

The above-mentioned structural arrangement can further realize the 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. After passing through the array substrate, the light irradiates the liquid crystal molecule layer. After being deflected by the liquid crystal molecules, the light is emitted to the color filter substrate. Then, after passing through the color resists of various colors on the color filter substrate, the light can be emitted on the surface of the display panel as light of various colors, and finally a pattern display is formed on the surface of the display panel.

[0066] 1) The special-shaped display panel of the present application sets special-shaped pixels in the special-shaped display area near the non-straight boundary, so that the special-shaped boundary area can also be displayed normally, improving the problem of special-shaped edge jaggedness. In addition, since the ratio between the special-shaped sub-pixels of different colors in the special-shaped display area is the same as the ratio between the special-shaped sub-pixels of different colors in the conventional display area, the display effect in the special-shaped display area can be made close to the display effect in the conventional display area, reducing the display difference and color deviation caused by the occlusion of the special-shaped pixels by the special-shaped boundary between the special-shaped display area and the conventional display area, thereby improving the display effect of the display panel.

[0067] 2) The display device of the present application includes the above-mentioned special-shaped display panel. Special-shaped pixels are set in the special-shaped display area near the non-linear boundary, so that the special-shaped boundary area can also be displayed normally, improving the problem of special-shaped edge jaggedness. In addition, since the ratio between the special-shaped sub-pixels of different colors in the special-shaped display area is the same as the ratio between the special-shaped sub-pixels of different colors in the conventional display area, the display effect in the special-shaped display area can be made close to the display effect in the conventional display area, reducing the display difference and color deviation caused by the occlusion of the special-shaped pixels by the special-shaped boundary between the special-shaped display area and the conventional display area, thereby improving the display effect of the display device.
