Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of display, and in particular, to a display panel and a display device. BACKGROUND

[0002] With the continuous development of display technology, users have higher and higher requirements for narrow frame of display panel. In order to meet the needs of users, a blind hole (AA Hole) for integrating some optical elements is usually arranged in the AA (Active Area) area of the display panel, which can be circular or elliptical in shape, so as to achieve narrow frame.

[0003] In addition, with the application of display technology in smart wear and other portable electronic devices, there are diversified requirements for the shape of display panel, and accordingly, special-shaped display panels have appeared. For example, display products with circular or arc-shaped screens have become very common.

[0004] However, whether the blind hole design or the special-shaped display panel design, the AA area of the display panel has a special-shaped boundary with a circular arc shape. Thus, in the display area close to the special-shaped boundary, the pixel units and the special-shaped boundary line cannot be completely matched, so that the pixel units are arranged in a jagged manner close to the edge of the special-shaped boundary. Thus, when displaying, the display area close to the special-shaped boundary presents a jagged visual effect. Therefore, the pattern of the special-shaped boundary position is not smooth, which affects the display effect of the display area close to the special-shaped boundary. SUMMARY

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. And in the absence of conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words “include” or “comprise” and the like used in this disclosure mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words “connect” or “connected” and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. “Inside”, “outside”, “upper”, “lower”, etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0038] It should be noted that the sizes and shapes of the figures in the accompanying drawings do not reflect the actual scale and are only for the purpose of illustrating the present disclosure. The same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0039] Figure 1 FIG. 1 is a schematic diagram of a pixel structure in which a circular blind hole H is provided in the AA area of ​​a display panel in the related art. Figure 1 As shown, the AA area includes a plurality of sub-pixels 10 arranged in an array, such as R, G, and B sub-pixels, which constitute a pixel unit P. In order to adapt to the irregular boundary Y1 of the display panel, some pixel units P are removed near the irregular boundary Y1, resulting in the formation of multiple step areas T in the AA area near the irregular boundary Y1. The area Q between the irregular boundary Y1 and the step area T cannot be provided with a complete pixel unit and is blocked by the black matrix (BM). When displaying, the pixel unit P located in the step area T is normally lit, while the black matrix in the area Q is almost opaque (the brightness is zero). Therefore, the brightness difference between the step area T and the area Q is large, resulting in a jagged effect. When displayed, the pattern at the position of the irregular boundary Y1 is not smooth, affecting the display effect of the display panel.

[0040] In the related art, in order to solve Figure 1 The pixel structure shown in the figure has a jagged effect at the position of the irregular boundary Y1 during display. A common method is to also block the pixel unit P near the irregular boundary Y1 with a black matrix (BM). Due to the blocking of the BM, the pixel opening area of ​​the pixel unit near the irregular boundary Y1 becomes smaller, thereby obtaining a certain grayscale transition effect from the irregular boundary Y1 to the AA area, realizing a gradual brightness change to weaken the jagged effect, as shown in FIG. Figure 2 However, Figure 2 As shown, in the related art, the circular blind hole H is divided into two parts (the upper and lower parts of the dotted line L), and the BM in the upper and lower parts of the dotted line L are both areas of the occluded pixel unit P close to the irregular boundary Y1, that is, the BM in the upper part of the dotted line L is the bottom of the occluded pixel unit P, and the BM in the lower part of the dotted line L is the top of the occluded pixel unit P. Specifically, as Figure 2 As shown, the BM blocking mode makes the BM in the two upper and lower pixel units P (in the dotted box A) closest to the dotted line L adjacent to each other, which leads to Figure 2 At the position of the dotted line L, a sudden change in display brightness will occur, resulting in a jaggies effect at the position of the dotted line L.

[0041] In view of this, in order to solve the above technical problems, the present disclosure provides a display panel, such as Figures 3-7 As shown, Figure 3A schematic view of a pixel structure for setting a blind hole in a display area AA of a display panel, Figure 4 For the purpose of clear illustration Figure 3 A schematic view of a corresponding display area, Figure 5 For Figure 3 A schematic view of a partial structure in a dashed box A1, Figure 6 For Figure 3 A schematic view of a partial structure in a dashed box A2, Figure 7 For Figure 3 A schematic view of a partial structure in a dashed box A3; the display panel has a display area AA, the display area AA has a special-shaped boundary Y1, and the display area AA includes a main display area AA1 and a transition display area AA2 located between the main display area AA1 and the special-shaped boundary Y1;

[0042] The display area AA includes a plurality of sub-pixels 10 arranged in an array along a row direction X and a column direction Y, each sub-pixel 10 in the transition display area AA2 has a light shielding block 20, and an area of the light shielding block 20 is smaller than an area of the sub-pixel 10;

[0043] The transition display area AA2 is divided into a first region A21, a second region A22 and a third region A23 arranged in sequence along an extension direction of the special-shaped boundary Y1;

[0044] In the first region A21 and the third region A23, each sub-pixel 10 includes one light shielding block 20, and the light shielding block 20 in each sub-pixel 10 is arranged close to the special-shaped boundary Y1;

[0045] In the second region A22, each sub-pixel 10 includes two light shielding blocks 20, and one of the light shielding blocks 20 in each sub-pixel 10 is arranged close to the first region A21, and the other light shielding block 20 is arranged close to the third region A23.

[0046] The display panel provided by the embodiments of the present disclosure can correspondingly reduce the original light transmittance of each sub-pixel 10 in the transition display area AA2 by setting the light shielding block 20 in each sub-pixel 10 in the transition display area AA2 to shield part of the area of the sub-pixel 10, and reduce the original brightness of the sub-pixel 10. In this way, the brightness of the transition display area AA2 can be reduced as a whole, so that the acuity of the human eye in capturing the display image around the special-shaped boundary Y1 is reduced during display, and finally the visual effect of the region where the special-shaped boundary Y1 is located having a sawtooth feeling can be reduced. In addition, the transition display area AA2 is re-divided into the first region A21, the second region A22 and the third region A23 by the present disclosure, and the positions of the light shielding blocks 20 for shielding the sub-pixels 10 are different in different regions, for example Figure 3The first area A21 in the first region A21 shields the lower part of the sub-pixel 10 (the upper part is the opening of the sub-pixel), the second area A22 shields the upper part and the lower part of the sub-pixel 10 (the middle part is the opening of the sub-pixel), and the third area A13 shields the upper part of the sub-pixel 10 (the lower part is the opening of the sub-pixel); in this way, the problem of display brightness mutation at the boundary between the upper and lower two divided regions in the related art is reduced. Therefore, the sub-pixel 10 shielding mode of the present disclosure makes the gray scale transition simulation effect of adjacent regions more smooth, which is more conducive to reducing the sawtooth feeling.

[0047] Optionally, as shown in Figure 3 The plurality of sub-pixels 10 can include a plurality of red sub-pixels (R), a plurality of green sub-pixels (G), and a plurality of blue sub-pixels (B), the sub-pixels in the same row are arranged in R, G, B, R, G, B, …, the colors of the sub-pixels in the same column are the same, and adjacent R, G, and B in the row direction constitute a pixel unit P. Of course, the colors and arrangement modes of the sub-pixels are not limited to the arrangement mode shown in the present disclosure Figure 3 .

[0048] In specific implementation, in the above display panel provided by the embodiment of the present disclosure, as shown in Figure 3 and Figure 4 The irregular boundary Y1 is circular, and of course can be elliptical or other arc-shaped, and the transition display area AA2 is arranged around the irregular boundary Y1, and the transition display area AA2 further includes a fourth area A24 between the first area A21 and the third area A23.

[0049] In the fourth area A24, each sub-pixel 10 includes two light shielding blocks 20, and one of the light shielding blocks 20 in each sub-pixel 10 shields the part of the sub-pixel 10 close to the first area A21, and the other light shielding block 20 shields the part of the sub-pixel 10 close to the third area A23. Specifically, the sub-pixel 10 shielding mode of the fourth area A24 is the same as the sub-pixel 10 shielding mode of the second area A22, so that the annular transition display area AA2 is divided into the first area A21, the second area A22, the third area A23, and the fourth area A24 in turn, and the sub-pixel 10 shielding mode provided by the embodiment of the present disclosure does not cause display brightness mutation between adjacent two regions in the transition display area AA2, and the present disclosure can make the gray scale transition simulation effect of adjacent two regions in the transition display area AA2 more smooth, which is more conducive to reducing the sawtooth feeling.

[0050] In specific implementation, in the above display panel provided by the embodiment of the present disclosure, as shown in Figures 3-7As shown, a plurality of sub-pixels with adjacent and different light-emitting colors constitute one pixel unit P, and each sub-pixel 10 in the same pixel unit P located in the transition display area AA2 has the same area of the light-blocking block 20. In this way, the light transmittance of each sub-pixel 10 in the same pixel unit P in the transition display area AA2 can be made the same, thereby avoiding the problem of over-brightness of a single color in the same pixel unit P.

[0051] In a specific implementation, in the display panel provided in the embodiments of the present disclosure, as shown in Figures 3-7 The display area AA includes a first center line L1 extending along the column direction Y and a second center line L2 extending along the row direction X, and the first region A21 includes a first sub-region A211 and a second sub-region A212 located on both sides of the first center line L1.

[0052] In the first sub-region A211 and the second sub-region A212, each row has at least one pixel unit P, and the area of the light-blocking block 20 in each pixel unit P gradually decreases along the row direction X and in the direction (aa) of the transition display area AA2 pointing to the main display area AA1. In this way, the transmittance of the sub-pixel 10 in the pixel unit P closer to the irregular boundary Y1 is lower, which can reduce the brightness around the irregular boundary Y1 to reduce the sawtooth effect. At the same time, the transmittance of the sub-pixel 10 in the pixel unit P farther from the irregular boundary Y1 is higher, thereby gradually increasing the brightness of the sub-pixel 10 in the aa direction, achieving uniform transition of brightness, reducing the brightness difference between adjacent pixel units P, and making the brightness of a plurality of pixel units P arranged in sequence smoothly transition, thereby further weakening the visual effect of the sawtooth effect of the area where the irregular boundary Y1 is located in the display process, and improving the display effect of the display panel.

[0053] In a specific implementation, in the display panel provided in the embodiments of the present disclosure, as shown in Figures 3-7 The pixel unit P located in the main display area AA1 is a first pixel unit P1, and the pixel unit P located in the transition display area AA2 is a second pixel unit P2.

[0054] In the first sub-region A211 and the second sub-region A212, except for the first row of second pixel units P, the second pixel unit P2 closest to the irregular boundary Y1 in the remaining rows of second pixel units P is located in the same column as the first pixel unit P1 closest to the irregular boundary Y1 in the previous row of first pixel units P1. In this way, the second pixel unit P2 in the first region A21 corresponding to the irregular boundary Y1 is provided with a light-blocking block, and the brightness in the first region A21 can be uniform, so that the brightness can smoothly transition from the first region A21 to the main display area AA1, further reducing the sawtooth effect at the position of the irregular boundary Y1.

[0055] In a specific implementation, in order to further reduce the sawtooth feeling at the position of the special-shaped boundary Y1, in the display panel provided in the embodiment of the present disclosure, as shown in Figure 3 , the first sub-region A211 and the second sub-region A212 can be symmetrically arranged about the first center line L1. Of course, this is not limited.

[0056] In a specific implementation, in order to further reduce the sawtooth feeling at the position of the special-shaped boundary Y1, in the display panel provided in the embodiment of the present disclosure, as shown in Figure 3 , the third region A23 and the first region A21 can be symmetrically arranged about the second center line L2. Of course, this is not limited.

[0057] In a specific implementation, in the display panel provided in the embodiment of the present disclosure, as shown in Figures 3-7 , the second region A22 includes a third sub-region A221 and a fourth sub-region A222 located on both sides of the second center line L2;

[0058] In the third sub-region A221 and the fourth sub-region A222, each row has a light shielding block 20 in the pixel unit P closest to the special-shaped boundary Y1, each column has at least one pixel unit P, and the area of the light shielding block 20 in each pixel unit P in the same column gradually increases in the column direction Y. In this way, the light shielding block 20 can be arranged in the pixel unit P in the second region A22 corresponding to the special-shaped boundary Y1, the brightness in the second region A22 can be uniform, and the brightness can smoothly transition from the second region A22 to the main display area AA1, thereby further reducing the sawtooth feeling at the position of the special-shaped boundary Y1.

[0059] In a specific implementation, in order to further reduce the sawtooth feeling at the position of the special-shaped boundary Y1, in the display panel provided in the embodiment of the present disclosure, as shown in Figure 3 , the third sub-region A221 and the fourth sub-region A222 can be symmetrically arranged about the second center line L2. Of course, this is not limited.

[0060] In a specific implementation, in order to further reduce the sawtooth feeling at the position of the special-shaped boundary Y1, in the display panel provided in the embodiment of the present disclosure, as shown in Figure 3 , the fourth region A24 and the second region A22 can be symmetrically arranged about the first center line L1. Of course, this is not limited.

[0061] In a specific implementation, as shown in Figure 3 , the width of the transition display area AA2 is not limited to Figure 3 , and can be set as needed.

[0062] In a specific implementation, as shown in Figure 3As shown, in the aa direction, the number of pixel units P with gradually decreasing light-shielding block 20 area in the same row is not limited to six, three, or two, and each pixel unit P corresponds to a display brightness, and the display brightness of different pixel units P is different (different gray scale), for example, the difference between the pixel gray scales of the two adjacent pixel units P in the same row in the transition display area AA2 can be an integer multiple of 8, 16, or 32.

[0063] Specifically, the display brightness of the display panel when displaying ranges from the darkest to the brightest, with a total of 256 brightness levels, referred to as 256 gray scales. In the embodiment of the present disclosure, the opening area of the sub-pixel is adjusted by using the light-shielding block, and the number of pixel units P in the same row in the transition display area AA2 can be designed in advance, for example, the difference between the pixel gray scales of the two adjacent pixel units P can be an integer multiple of 16. In the transition display area AA2, 14 pixel units P in the same row can be designed in advance, and the difference between the gray scales of the two adjacent pixel units P is an integer multiple of 16, for example, the sub-pixel in the pixel unit P closest to the special-shaped boundary Y1 can be 15 gray scales, and the sub-pixel in the pixel unit P farthest from the special-shaped boundary Y1 can be 239 gray scales. Of course, the difference between the gray scales of the pixel units P with different brightness in the display panel can be designed according to different brightness requirements. The above-mentioned difference between the gray scales of the adjacent pixel units P is an integer multiple of 16, which is only one possible embodiment, and the present disclosure does not limit this.

[0064] In a specific implementation, in the above-mentioned display panel provided by the embodiment of the present disclosure, as shown in Figure 3 The central angle (2θ1) of the first region A21 and the third region A23 can be 71°-81°, that is, θ1 is 35.5°-40.5°; preferably, the central angle (2θ1) of the first region A21 and the third region A23 can be 76°, that is, θ1 is 38°; the central angle (2θ2) of the second region A22 and the fourth region A24 can be 99°-109°, that is, θ2 is 49.5°-54.5°; preferably, the central angle (2θ2) of the second region A22 and the fourth region A24 can be 104°, that is, θ2 is 52°. In this way, the brightness transition effect of the adjacent two regions in the first region A21, the second region A22, the third region A23, and the fourth region A24 is more natural and smooth, and the problem of brightness mutation does not occur.

[0065] In an optional embodiment, the first sub-area A211 and the second sub-area A212 are symmetrical about the first center line L1, the third sub-area A221 and the fourth sub-area A222 are symmetrical about the second center line L2, and the fifth and sixth sub-areas are symmetrical about the first center line L1, and the area formed by the fifth and sixth sub-areas is symmetrical with the area formed by the first sub-area A211 and the second sub-area A212 about the second center line L2; and the seventh and eighth sub-areas are symmetrical about the second center line L2, and the area formed by the seventh and eighth sub-areas is symmetrical with the area formed by the third sub-area A221 and the fourth sub-area A222 about the first center line L1. The central angles corresponding to the above eight sub-areas are equal, all 45 degrees. That is, the second area A22 can include the above third sub-area A221 and the fourth sub-area A222, as well as the first sub-area A211 and the fifth sub-area. That is, the second area A22 includes the third sub-area A221 and the fourth sub-area A222 in which the area of ​​the light shielding blocks 20 in each pixel unit P increases or decreases along the column direction Y, and the first sub-area A211 and the fifth sub-area in which the area of ​​the light shielding blocks 20 in each pixel unit P increases or decreases along the row direction X. The fourth area A24 is symmetrical to the second area A22 about the first center line L1.

[0066] In specific implementation, in the above display panel provided in the embodiment of the present disclosure, if Figure 3 As shown, the shape of the light shielding block 20 and the shape of the sub-pixel 10 can be rectangular, and the width of the light shielding block 20 is the same as the width of the sub-pixel 10, so that the height of the light shielding block 20 is less than the height of the sub-pixel 10. Specifically, the material of the light shielding block 20 can be a black matrix (BM).

[0067] Specifically, if Figure 3 As shown, the light shielding strips 30 are arranged horizontally and vertically to define multiple sub-pixels 10. The material of the light shielding strips 30 and the light shielding block 20 is the same, both are BM, and are an integrated structure. In this way, the light shielding strips 30 and the light shielding block 20 can be formed in a single patterning process, reducing production costs.

[0068] In a specific implementation, in order to make the brightness transition effect between the second area and the fourth area more natural and smooth, in the above-mentioned display panel provided in the embodiment of the present disclosure, as shown in FIG. Figure 3 As shown, in the second area A22 and the fourth area A24 , the two light shielding blocks 20 in the sub-pixel 10 may be symmetrically arranged about the center of the sub-pixel 10 .

[0069] In specific implementation, in the above display panel provided in the embodiment of the present disclosure, if Figure 3 As shown, the embodiment of the present disclosure takes the annular blind hole H as a circle as an example, but it can also be an ellipse.

[0070] In a specific implementation, the display panel provided by the embodiments of the present disclosure is taken as an example with the display area having a blind hole, but is not limited thereto. For example, the display panel of the embodiments of the present disclosure can be a special-shaped display panel such as a circular or elliptical display panel, or the display panel of the embodiments of the present disclosure can be a special-shaped display panel with an R corner, which can all adopt the embodiments provided by the embodiments of the present disclosure to design the shielding of the sub-pixels by re-partitioning the transition display area.

[0071] In a specific implementation, in the display panel provided by the embodiments of the present disclosure, other functional structures familiar to those skilled in the art can also be included, and the embodiments of the present disclosure are only illustratively described the partitioning and shielding manner of the sub-pixels to make the display panel not appear the phenomenon of brightness mutation.

[0072] Based on the same inventive concept, the embodiments of the present disclosure also provide a display device including any one of the display panels provided by the embodiments of the present disclosure, as shown in Figure 3 The display area AA of the display panel has a circular or elliptical blind hole H for placing an optical element.

[0073] Of course, the display area of the display panel provided by the embodiments of the present disclosure can be circular or elliptical, that is, the display panel itself can be a special-shaped display panel such as a circular or elliptical display panel, for example, a wearable display product, etc.

[0074] The display device can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator, etc. The implementation of the display device can refer to the embodiments of the display panel described above, and the repeated parts will not be described herein.

[0075] In some embodiments, the display panel can be a liquid crystal display panel (LCD), and the display device further includes a backlight module, and the display panel is located on the light-emitting side of the backlight module.

[0076] Of course, in a specific implementation, the display panel can also be an organic light-emitting display panel (OLED).

[0077] The display panel and the display device provided by the embodiments of the present disclosure can correspondingly reduce the original transmittance of each sub-pixel in the transition display area by arranging the light shielding block that shields part of the area of the sub-pixel in each sub-pixel in the transition display area, and reduce the original brightness of the sub-pixel. In this way, the brightness of the transition display area can be reduced as a whole, so that the acuity of the human eye in capturing the image displayed around the irregular boundary is reduced in the process of display, and finally the visual effect of the region where the irregular boundary is located having a sawtooth feeling can be reduced. In addition, the embodiments of the present disclosure redivide the transition display area into a first region, a second region and a third region, and the positions of the light shielding blocks shielding the sub-pixels are different in different regions, for example ​ the first region shields the lower part of the sub-pixel (the upper part is the opening of the sub-pixel), the second region shields the upper part and the lower part of the sub-pixel (the middle part is the opening of the sub-pixel), and the third region shields the upper part of the sub-pixel (the lower part is the opening of the sub-pixel); in this way, the problem of display brightness mutation at the boundary between the upper and lower regions in the related art is eliminated. Therefore, the sub-pixel shielding mode of the present disclosure makes the gray scale transition simulation effect of adjacent regions more smooth, and is more conducive to reducing the sawtooth feeling.

[0078] Although the preferred embodiments of the present disclosure have been described, those skilled in the art can make additional changes and modifications to the embodiments once they know the basic inventive concept. Therefore, the appended claims are intended to be interpreted as including all the preferred embodiments and all the changes and modifications falling within the scope of the present disclosure.

[0079] Obviously, those skilled in the art can make various modifications and variations to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalent technologies, the present disclosure also intends to include these modifications and variations.
