The present application provides a display panel, and the display panel includes but is not limited to the following embodiments or a combination thereof.

In one embodiment, as shown inFIG.1toFIG.3, the display panel100includes: a central portion10having a plurality of first sides01and a plurality of second sides02, wherein each of the second sides02is connected to corresponding two adjacent first sides01; and a plurality of peripheral portions20, wherein each of the peripheral portions20extends outward from a corresponding first side01of the central portion10in a direction away from the central portion10. Each of the peripheral portions20further includes a third side03and a fourth side04opposite to each other, and each of the second sides02is connected between a corresponding third side03of one of two corresponding peripheral portions20adjacent to the second side02and a corresponding fourth side04of the other of the two corresponding peripheral portions Wherein, when the central portion10and the peripheral portions20unfold into a plane, each of the peripheral portions20is located within a region A jointly defined by an extension line of the corresponding first side01and respective two extension lines b and c of the two first sides01adjacent to the corresponding first side01, and each of the second sides02is located within a region B jointly defined by an extension line d of a corresponding third side03adjacent to the second side02, an extension line e of a corresponding fourth side04adjacent to the second side02, and respective two extension lines f and g of two corresponding first sides01adjacent to the second side02.

Specifically, the shapes of the first sides01may be the same or different, and the shapes of the second sides02may be the same or different. The shapes of the third sides03may be the same or different, and the shapes of the fourth sides04may be the same or different. In this embodiment, the specific shapes of the first sides01, the second sides02, the third sides03, and the fourth sides04are not limited. The shapes of the first side01, the second side02, the third side03, and the fourth side04have no specific relationship, and the shapes of the four can be combined arbitrarily. Further, the numbers of the first sides01, the second sides02, the third sides03, and the fourth sides04are not limited. Understandably, it is only required that the relative positional relationships of the first sides01, the second sides02, the third sides03, and the fourth sides04meet the foregoing requirements. Here, the description is made by taking as an example that the first sides01are all straight segments, and the angle formed by the intersection of two adjacent extension lines of the first sides01is 90°. It should be noted that each peripheral portion20includes at least one corresponding first side01, one corresponding third side03, and one corresponding fourth side04.

On one hand, as shown inFIG.1toFIG.3, when the central portion10and the peripheral portions20unfold into a plane, each of the peripheral portions20extends outward from a corresponding first side01in a direction away from the central portion That is, each of the peripheral portion20must also be positioned between the corresponding first side01and a corresponding outer edge h of the display panel100. Therefore, region A is a region jointly defined by a corresponding first side01, a corresponding extension line b, a corresponding extension line c, and a corresponding outer edge h. It is understandable that each of the peripheral portions20does not exceed the corresponding extension line b and the corresponding extension line c so that when two adjacent peripheral portions20of the display panel100bends downward along the first sides01thereof, the two adjacent peripheral portions20will not overlap and cause wrinkles.

On the other hand, as shown inFIG.1toFIG.3, when the central portion10and the peripheral portions20unfold into a plane, an extension line d of the third side03corresponding to each of the second sides02intersects the extension line e of the corresponding fourth side04, and the two corresponding extension lines f and g of the first side01intersect, that is, the four extension lines d, e, f, and g jointly define the region B. First, take the extension lines f and g as two boundaries of the region B. When the display panel100bends downward along corresponding straight lines of two adjacent first sides01, the central portion10does not overlap and causes wrinkles. Secondly, take the extension lines d and e as the other two boundaries of region B, an area between the two adjacent first sides01can be effectively increased to increase the display area of the central portion10and increase the screen-to-body ratio of the display panel100.

In one embodiment, as shown inFIG.1, the second side02is curved, and a convex direction of the second side02is away from the center of the central portion10. It is understandable that, on the basis of taking the extension lines d and e as the other two boundaries of the region B, the second side02is set to be a curved shape with a convex direction away from the center of the central portion10. It is possible to further increase the area of the region of the display panel100located between the corresponding two adjacent first sides01, and the acute angles of the display panel100can be alleviated by setting the second side02in a curved shape, so as to improve the aesthetics and visual effect. It can also reduce the difficulty of forming the second side02by laser cutting, and prevent the decrease in yield due to sudden changes in the traveling angle of laser cutting.

Certainly, as shown inFIG.2, the second side02can also be a straight line, that is, laser cutting can be performed along a straight path from one of endpoints of a corresponding peripheral portion20to the other endpoint of the corresponding peripheral portion20to form the second side02. This can further reduce the difficulty of the laser cutting to form the second side02. Certainly, the second side02can also be a curved line with a convex direction close to the center of the central portion10, or the second side02may also include at least one curved section and at least one straight section. As long as the second side02is located in region B, the peripheral region of the display panel100can be prevented from wrinkling during bending. This further alleviates the phenomenon of film layer peeling in the peripheral region of the display panel100. Alternately, as shown inFIG.3, each second side02may include a first sub-side021and a second sub-side022. Specifically, the extension lines g and f of two adjacent first sides01may overlap with the first sub-side021and the second sub-side022of the second side02located between the two adjacent first sides01, that is, the second side02may be formed by the intersection of the extension lines f and g of the two corresponding first sides01. It is understandable that the second side02in this embodiment is still located in region B, and the second side02overlaps the extension lines f and g, which can maximize the display area of the central portion10in the display panel100to increase the screen-to-body ratio of the display panel100.

In one embodiment, as shown inFIG.1, the second side02is arc-shaped. It is understandable that, compared to the second side02being set to other curved shapes, the second side02set to be an arc-shaped can make the second side02have a constant curvature to improve the fluency and continuity of the second side02. This can further realize an ultra-wide-angle display to improve the aesthetics and visual effects of the display panel100and allows the laser to cut at a constant rate of change in direction. This effectively reduces the difficulty of laser cutting to form the second side02and also effectively prevents sudden changes in the angle of travel of laser cutting to reduce yield. Further, in one embodiment, as shown inFIG.1, the central angle corresponding to the second side02is 90°. Specifically, the angle formed by the intersection of the respective extension lines of the two adjacent first sides01in the display panel100may be set to 90° to set the outline of the central portion10to be approximately rectangular. Further, the central angle corresponding to the arc-shaped second side02is set to 90°, so that the shape of the second side02is approximately a corner of a rectangle, that is, the second side02may be tangent to two extension lines f and g of two corresponding adjacent first sides01. Therefore, the screen-to-body ratio of the display panel100can be increased while maintaining the aesthetics and visual effects of the display panel100. Certainly, the central angle corresponding to the second side02can also be set to other angles according to the angle between two adjacent first sides01and the arc length requirements of the second side02.

In one embodiment, as shown inFIG.1, at least one of the third side03or the fourth side04is curved, and a convex direction of at least one of the third side03or the fourth side04is away from the center of the central portion10. On one hand, under the premise that the second side02is a curved line with a convex direction away from the center of the central portion10, a convex direction of at least one of the third side03or the fourth side04is also set to be away from the center of the central portion10. The display panel100can be made into a convex shape as a whole to unify the boundary shape of the display panel100, so as to achieve an ultra-wide-angle display to improve the aesthetics and visual effects of the display panel100and prevent serious picture loss due to large border differences. On the other hand, intersection point D is a point formed by an intersection of the third side03and the second side02. When the third side03and the second side02are both a curved line with a convex direction away from the center of the central portion10, two parts of the third side and the corresponding second side respectively close to the intersection point D protrude from the intersection point D so that a concave portion with two convex sides is formed at the intersection point D. When the third side03breaks, a crack that extends through the intersection point D can be blocked by the concave portion at the intersection point D so the crack cannot extend smoothly and transition to the second side02. That is, it can prevent the crack from extending to the second side02. When the second side02breaks, a crack that extends through the intersection point D can be blocked by the concave portion at the intersection point D so the crack cannot extend smoothly and transition to the third side03. That is, it can prevent the crack from extending to the third side03, which alleviates the phenomenon of film layer peeling in the region around the display panel100.

Certainly, as shown inFIG.2andFIG.3, the third side03and the fourth side04can be straight segments, which can facilitate laser cutting. Further, as shown inFIG.2, the shape of each peripheral portion20may be a rectangle extending from the corresponding first side01of the central portion10in a direction away from the central portion10. In this way, the area of the peripheral portion20can be increased while preventing wrinkles caused by bending, so as to increase the screen-to-body ratio of the display panel100.

In one embodiment, as shown inFIG.1, at least one of the third side03or the fourth side04is arc-shaped. According to the above analysis, for example, compared to the third side03being set to other curved shapes, setting the third side03in an arc-shaped can make the third side03have a constant curvature to improve the fluency and continuity of the third side03, which can further realize an ultra-wide-angle display to improve the aesthetics and visual effects of the display panel100and allows the laser cutting to perform at a constant rate of change in directions. It effectively reduces the difficulty of laser cutting to form the third side03, and also effectively prevents sudden changes in the angle of laser travel when performing laser cutting, which reduces the yield. It should be noted that the position of the center of circle corresponding to the third side03is not limited here, that is, the center of circle can be located in the central portion10or the corresponding peripheral portion20, as long as each peripheral portion20is located within the corresponding region A. Further, the third side03and the fourth side04may both be arc-shaped. Further, in order to reduce the interference between two adjacent peripheral portions20, both the center of circle corresponding to the third side03and the center of circle corresponding to the fourth side04can be located in the central portion10, that is, the third side03gradually moves away from the corresponding second side02from the corresponding first side01in a direction away from the central portion10. Similarly, the fourth side04gradually moves away from the corresponding second side02from the corresponding first side01in a direction away from the central portion10.

In one embodiment, as shown inFIG.1, the central angle corresponding to at least one of the third side03or the fourth side04is less than 90°. Understandably, on the basis that both the center of circle corresponding to the third side03and the center of circle corresponding to the fourth side04can be located in the central portion10, if the central angle corresponding to the third side03is larger, the direction of the third side03will change too quickly. It will further cause the length of the third side03to be too long so that the intersection E of the third side03and the corresponding outer edge h of the display panel100is too close to the center of the central portion10. As a result, the length of the fifth side05disposed opposite to the corresponding first side01in the corresponding peripheral portion20is too short, so that the area of the corresponding peripheral portion20is too small. Therefore, setting the central angle corresponding to the third side03to be less than 90° can effectively reduce the length of the third side03so as to increase the length of the fifth side05of the corresponding peripheral portion20. Thus, the area of the corresponding peripheral portion20is increased to increase the screen-to-body ratio of the display panel100.

In one embodiment, as shown inFIG.1andFIG.3, the length of each fifth side05is less than the length of the corresponding first side01. Understandably, no matter what the specific shapes of the third side03and the fourth side04are, because the length of each fifth side05is less than the length of the corresponding first side01, at least one of the third side03or the fourth side04meets a requirement of “from the corresponding first side01in a direction away from the central portion10gradually away from the corresponding second side02”. On one hand, according to the above analysis, the interference between two adjacent peripheral portions20can be effectively reduced. On the other hand, the size of each of the peripheral portions20as a whole from the corresponding first side01in a direction away from the central portion is decreasing, so that when the cover plate is attached to the display panel100, air bubbles need to be squeezed out from the central portion10to the peripheral portions and from the first side01to the corresponding outer edge h, which facilitates the discharge of the air bubbles from at least one of the third side03or the fourth side04and prevents the accumulation of the air bubbles.

Specifically, as shown inFIG.1andFIG.3, the size of each of the peripheral portions20gradually decreases from a corresponding first side01in a direction away from the central portion10. Understandably, on the basis that the length of the fifth side of each of the peripheral portions20is less than the length of the corresponding first side01, if each of the peripheral portions20is cut into long strips of equal width in a direction from a corresponding first side01in a direction away from the central portion then in every two adjacent strips, the length of the strip far away from the central portion10is less than the length of the strip close to the central portion10. It is more conducive for air bubbles to be discharged from at least one of the third side03or the fourth side04to prevent the accumulation of air bubbles. Specifically, as shown inFIG.1andFIG.3, the two ends of the fifth side05in each of the peripheral portions20do not exceed the range of the two ends of the corresponding first side01. It is understandable that no matter what the specific shapes of the third side03and the fourth side04are, as long as both ends of the fifth side05of the peripheral portion20do not exceed the range of the two ends of the corresponding first side01, the bubbles can be discharged from the third side03and the fourth side04.

In one embodiment, at least one of the peripheral portions20is provided with virtual keys, wherein, the number of the virtual key is at least one. For example, when the display panel100performs imaging display, the user can touch the central portion or the peripheral portion20to make the peripheral portion20present the virtual key. Further, the user can touch a corresponding virtual key to realize a corresponding function.

In one embodiment, the display panel00includes a display film layer and a cover plate. The display film layer includes the central portion10and a plurality of the peripheral portions20. The cover plate is disposed on the display film layer to encapsulate the display film layer. The cover plate includes a central region and a plurality of peripheral regions, and the central region is arranged corresponding to the central portion10to cover the central portion10. Each of the peripheral regions are arranged corresponding to each of the peripheral portions20to cover the corresponding peripheral portions20. Further, the display panel00is an organic light-emitting diode (OLED) display panel.

A display panel and a display device are provided. The display panel includes a central portion and a plurality of peripheral portions. The central portion includes a plurality of first sides and a plurality of second sides, wherein each of the second sides is connected to corresponding two adjacent first sides. Each of the peripheral portions extends outward from a corresponding first side of the central portion in a direction away from the central portion. Each of the peripheral portions further includes a third side and a fourth side arranged oppositely, and each of the second sides is connected between a corresponding third side of one of two corresponding peripheral portions adjacent to the second side and a corresponding fourth side of the other of the two corresponding peripheral portions. When the central portion and the peripheral portions unfold into a plane, each of the peripheral portions is set to be located within a region jointly defined by an extension line of the corresponding first side and two extension lines of two first sides adjacent to the corresponding first side, so as to ensure that when the display panel bends downward along the line to which the two adjacent first sides belong, the corresponding two adjacent peripheral portions will not be overlapped, and each of the second sides is located within a region jointly defined by an extension line of a corresponding third side adjacent to the second side, an extension line of a corresponding fourth side adjacent to the second side, and two extension lines of two corresponding first sides adjacent to the second side, to ensure that when the display panel bends downward along the line to which the first side belongs, the film layer at the central portion does not overlap. As described above, this solution can alleviate the wrinkles phenomenon in the region around the display panel when it bends, and further alleviates the phenomenon of film peeling in the region around the display panel.
