[0025] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed in itself. In addition, the examples of various specific processes and materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials. In some instances, methods, means, components and circuits well known to those skilled in the art are not described in detail, so as to highlight the subject matter of the present application.

[0026] The present application mainly provides a display device, which includes: a flexible display panel, which includes a plurality of panel bending portions distributed in a ring shape; a cover plate, which includes an inner wall and an outer wall arranged on one side of the inner wall, the inner wall includes a plurality of inner wall bending portions distributed in a ring shape, and the outer wall includes a plurality of outer wall bending portions arranged opposite to the inner wall; wherein: each of the inner wall bending portions is respectively fitted with the corresponding panel bending portion, and the bending direction of each of the inner wall bending portions is opposite to the bending direction of the outer wall bending portion corresponding to the inner wall bending portion.

[0027] Compared with the curved screen in the prior art, the present application provides a cover plate similar to a "bottle cap", and provides a plurality of inner wall bending portions distributed in an annular manner on the inner wall of the cover plate, and at the same time provides a plurality of outer wall bending portions opposite to the inner wall on the outer wall of the cover plate, and makes the bending direction of each inner wall bending portion opposite to the bending direction of the outer wall bending portion corresponding to the inner wall bending portion, so as to achieve curved bonding of the flexible display panel and the cover plate, improve the wrinkle problem of the flexible display panel bonding, optimize the optical path, realize a full-curved screen with multi-directional display, and improve the display effect.

[0028] Among them, the flexible display panel of the present application can be a whole flat display panel before laminating. Since the flexible display panel can be flat before laminating, the present application designs the cover plate to be a structure similar to a "bottle cap". When laminating the flexible display panel with the cover plate, the flat flexible display panel can be folded into the cover plate according to the structure of the cover plate, thereby realizing the curved lamination of the flexible display panel and the cover plate. At the same time, since the inner wall of the cover plate is provided with a plurality of inner wall bending portions distributed in an annular manner, and a plurality of outer wall bending portions arranged opposite to the inner wall are provided on the outer wall of the cover plate, and the bending direction of each inner wall bending portion is opposite to the bending direction of the outer wall bending portion corresponding to the inner wall bending portion, in the process of laminating the flexible display panel with the cover plate, the influence of the wrinkle problem can be offset, so that the wrinkle problem of the flexible display panel is improved.

[0029] Figure 1 A top view showing the flexible display panel and the cover plate attached to each other according to an embodiment of the present application is shown.

[0030] See also Figure 1 , the flexible display panel 1, the cover plate 2, and the display device 3 formed by the flexible display panel 1 and the cover plate 2 are all presented from a top view. The flexible display panel 1 can be attached to the cover plate 2 and structurally fit with the cover plate 2 to form the display device 3.

[0031] Among them, for the flexible display panel 1, the flexible display panel can be rolled into a shape similar to a cylinder from a flat surface before bonding, and further folded into the shape of the boundary 11. The pre-folding line 12 represents the line after the boundary 11 is folded inward, and a pre-folding area is formed between the pre-folding line 12 and the boundary 11. The pre-folding line 12 can be a polygon formed by multiple arc segments.

[0032] exist Figure 1 In the figure, for the cover plate 2, the outer wall 13 of the cover plate 2 can be circular, representing a smooth two-dimensional plane, which can be an inclined plane with a certain angle to the direction perpendicular to the paper surface, or a plane or curved surface perpendicular to the paper surface. The outer wall 13 can be folded along the boundary 16, and the boundary 16 after the outer wall 13 is folded can form a plurality of interlayers composed of convex arc segments and concave arc segments with the inner wall 14. The inner wall 14 of the cover plate 2 can be a polygon arranged in an annular shape, corresponding to the pre-folding line 12 of the flexible display panel. The transition line 15 can be circular, representing the inner boundary surrounded by the inner wall 14.

[0033] In the process of laminating the flexible display panel 1 and the cover plate 2, the flexible display panel 1 can be folded along the pre-folding line 12 first, and then laminarized between the transition line 15 and the inner wall 14 of the cover plate, and closely contacted with the inner wall 14 of the cover plate, thereby forming the display device 3. It is worth noting that the display device 3 may also include other components, so for the display device 3, a gap may also be provided between the pre-folding line 12 of the flexible display panel 1 and the inner wall 14 of the cover plate.

[0034] In one example, the flexible display panel may be an OLED display panel. Of course, for other types of display panels such as LCD, the structure of the display device and the light-emitting circuit may be adjusted accordingly based on the inventive concept of the present application. It is understood that the present application does not limit the type of the flexible display panel.

[0035] Figure 2 A cross-sectional view showing a first display device according to an embodiment of the present application.

[0036] like Figure 2 As shown, along Figure 1 A cross section is made at a fixed position of the display device 3 in the embodiment to obtain a cross-sectional view of the display device from a top view. Figure 2 In the flexible display panel 21, a plurality of panel bending portions distributed in an annular manner may be included, and each of the panel bending portions may include a first panel bending surface 211 and a second panel bending surface 212. The first panel bending surface 211 and the second panel bending surface 212 are both curved surfaces and smoothly transition to each other. The bending directions of the adjacent first panel bending surfaces 211 and the second panel bending surfaces 212 are mirror-symmetrical about the common edge of the first panel bending surface 211 and the second panel bending surface 212. For example, the bending direction of the first panel bending surface 211 is from Figure 2 The second panel bending surface 212 is bent from the lower left to the upper right, and the bending direction of the second panel bending surface 212 is from Figure 2 The upper left corner is bent to the lower right corner. Figure 2 In the embodiment, two adjacent panel bending portions can form Figure 2 The wavy structure shown.

[0037] Furthermore, if Figure 2 As shown, the cover plate includes an inner wall and an outer wall arranged on one side of the inner wall, and the inner wall includes a plurality of inner wall bending portions distributed in an annular manner. Specifically, the inner wall 22 includes a first inner wall bending surface 221 and a second inner wall bending surface 222. The first inner wall bending surface 221 and the second inner wall bending surface 222 are both curved surfaces, and smoothly transition to each other. The direction of the inner wall 22 can be the same as the direction of the flexible display panel 21, and each of the first inner wall bending surfaces can be fitted with the corresponding first panel bending surface, and each of the second inner wall bending surfaces can be fitted with the corresponding second panel bending surface.

[0038] Continue to see Figure 2 , the cover plate further includes an outer wall disposed on one side of the inner wall. The outer wall includes a first outer wall and a second outer wall. The first outer wall includes a plurality of outer wall bending portions disposed opposite to the inner wall. Specifically, the outer wall bending portion may include a first outer wall bending surface and a second outer wall bending surface. For example, Figure 2 In the embodiment, the outer wall 23 includes a first outer wall bending surface 231 and a second outer wall bending surface 232. The first outer wall bending surface 231 and the second outer wall bending surface 232 are both curved surfaces and smoothly transition to each other.

[0039] exist Figure 2 In the embodiment, the second outer wall 234 can form the outer wall together with the first outer wall, the first outer wall can be the inner side of the outer wall, and the second outer wall can be the inner side of the outer wall. The second outer wall 234 can be a curved surface, which smoothly transitions to the first outer wall. It should be noted that Figure 2 The second outer wall 234 in the embodiment can be a part of the entire cover plate, and the cover plate can be arranged around, so the second outer wall 234 can be a curved surface that surrounds 360°. The second outer wall can define the boundary of the outer wall together with the first outer wall. It can be understood that the present application does not limit how to arrange the second outer wall.

[0040] Furthermore, the outer wall bending portion includes a first outer wall bending surface and a second outer wall bending surface, the first outer wall bending surface and the second outer wall bending surface respectively include multiple edges, and the first outer wall bending surface and the second outer wall bending surface of the same outer wall bending portion are provided with a common edge shared by the first outer wall bending surface and the second outer wall bending surface.

[0041] Figure 3 A front view of a first display device according to an embodiment of the present application is shown.

[0042] See also Figure 3 , each of the first outer wall bending surface and the second outer wall bending surface may include a plurality of edges, and the plurality of edges include at least one non-common edge and at least one common edge. The first outer wall bending surface 231 and the second outer wall bending surface 232 are located in the same outer wall bending portion. The first outer wall bending surface 231 and the second outer wall bending surface 232 are provided with a common edge shared by the first outer wall bending surface 231 and the second outer wall bending surface 232. The first outer wall bending surface 231 and the second outer wall bending surface adjacent to the left are provided with a common edge 34.

[0043] Combination Figure 1 , Figure 2 and Figure 3It can be seen that in addition to the cover plate including an inner wall and an outer wall arranged on one side of the inner wall, the cover plate may also include a top surface 33, an outer surface 32 and a bottom surface 31. Among them, the boundary of the bottom surface 31 can be defined by the second outer wall 234. The plane structure of the top surface 33 can be the same as the plane structure of the bottom surface. The total area of ​​the bottom surface can be larger than the total area of ​​the top surface, so that the entire cover plate forms a shape similar to a truncated cone. The top surface and the bottom surface can be flat, or convex or concave curved surfaces. The outer surface 32 can be jointly defined by the bottom surface 31 and the top surface 33. The outer surface of the outer wall of the cover plate can be a smooth curved surface shape, and the inner surface of the outer wall of the cover plate can be arranged along the direction of the inner wall.

[0044] Furthermore, the first outer wall bending surface and the second outer wall bending surface also respectively include at least one non-common edge, the non-common edges of the first outer wall bending surface and the non-common edges of the second outer wall bending surface are both arc segments, and the first outer wall bending surface and the second outer wall bending surface are both curved surfaces.

[0045] For example, see Figure 3 , the bottom edge of the first outer wall bending surface 231 is a non-common edge, and the left side edge of the first outer wall bending surface 231 is a common edge 34. The common edge 34 may be a common edge of the first outer wall bending surface 231 and the second outer wall bending surface adjacent to the left, or a common edge of the first inner wall bending surface 221 and the second inner wall bending surface adjacent to the left, or a common edge of the first outer wall bending surface 231 and the first inner wall bending surface 221. The common edge 34 may be a straight line segment, and the non-common edge of the first outer wall bending surface 231 and the non-common edge of the first inner wall bending surface 221 may both be arc segments.

[0046] Furthermore, the first outer wall bending surfaces and the second outer wall bending surfaces of the plurality of outer wall bending portions are arranged alternately with each other, and the plurality of outer wall bending portions form a wavy shape with alternating convex and concave portions.

[0047] For example, in Figure 2 In the figure, the first outer wall bending surface 231 and the second outer wall bending surface 232 located at the same outer wall bending portion are concave when viewed from top to bottom. Correspondingly, the two outer wall bending portions adjacent to the outer wall bending portion where the first outer wall bending surface 231 and the second outer wall bending surface 232 are located can both be convex, thereby forming a wavy shape with alternating convex and concave shapes. It can be understood that the curvature of the first outer wall bending surface can be different from the curvature of the second outer wall bending surface. Similarly, the curvature of the first inner wall bending surface can be different from the curvature of the second inner wall bending surface, and the curvature of the first panel bending surface can also be different from the curvature of the second inner wall bending surface. The present application does not limit the curvature of the outer wall bending surface, the inner wall bending surface, and the panel bending surface.

[0048] Further, when the bending direction of the inner wall bending portion is concave, the bending direction of the outer wall bending portion corresponding to the inner wall bending portion is convex; when the bending direction of the inner wall bending portion is convex, the bending direction of the outer wall bending portion corresponding to the inner wall bending portion is concave.

[0049] by Figure 2 For example, the first outer wall bending surface 231 and the second outer wall bending surface 232 are located in the same outer wall bending portion, and the outer wall bending portion is concave from top to bottom; correspondingly, the first inner wall bending surface 221 and the second inner wall bending surface 222 are located in the same inner wall bending portion, and the inner wall bending portion is convex from top to bottom; the first panel bending surface 211 and the second panel bending surface 212 are located in the same panel bending portion, and the panel bending portion is convex from top to bottom. That is, the bending direction of each inner wall bending portion is opposite to the bending direction of the outer wall bending portion corresponding to the inner wall bending portion, and the bending direction of each panel bending portion is the same as the bending direction of the inner wall bending portion corresponding to the panel bending portion.

[0050] Furthermore, each of the inner wall bending portions is respectively surrounded by the outer wall bending portion corresponding to the inner wall bending portion to form a plurality of interlayers arranged at intervals, wherein: at least one of the interlayers is unfilled, or at least one of the interlayers is filled with transparent material.

[0051] refer to Figure 2 The second outer wall bending surface 232 and the first outer wall bending surface 233 can be located in the same outer wall bending portion, and the outer wall bending portion is convex from top to bottom; the second inner wall bending surface 222 and the first inner wall bending surface 223 can be located in the same inner wall bending portion, and the inner wall bending portion is concave from top to bottom. The convex outer wall bending portion and the concave outer wall bending portion can enclose a sandwich, and the sandwich can be filled with no material or with a transparent material. The transparent material can be a material with a low refractive index, and the refractive index of the transparent material can also be determined according to needs.

[0052] It should be noted that the embodiment of the present application utilizes the difference in design between the inner wall and the outer wall to realize the function of the lens. A plurality of interlayers are arranged between the inner wall and the outer wall. These interlayers can be used as buffer layers for the optical path. In order to further improve the optical path, these interlayers do not adopt an integrated design, and different interlayers are independent of each other.

[0053] exist Figure 2In the flexible display panel 21, a plurality of light-emitting components may be arranged, and the plurality of light-emitting components are arranged on the plurality of panel bending portions, respectively. The light-emitting components may be light-emitting devices such as LEDs. For example, the flexible display panel is closely attached to the inner wall, so the light path emitted by the light-emitting component B1 can vertically pass through the second inner wall bending surface 222 to reach the interlayer, and the light path reaches the inner surface of the outer wall after passing through the interlayer. At this time, the light path is a convergent light path. Since the structure corresponding to the outer wall is a "concave lens" structure, after the light path passes through the second outer wall, the light path is refracted into a vertically upward parallel light L1.

[0054] Further, the inner wall bending portion includes a first inner wall bending surface and a second inner wall bending surface, the first inner wall bending surfaces and the second inner wall bending surfaces of the multiple inner wall bending portions are arranged alternately, and the first inner wall bending surface and the second inner wall bending surface respectively include a common edge shared by the first inner wall bending surface and the second inner wall bending surface and at least one non-common edge. Among them, in the inner wall bending portion, at least one of the non-common edges is a straight line segment, or at least one of the non-common edges is an arc segment.

[0055] Figure 4 A top view of a second display device according to an embodiment of the present application is shown.

[0056] See also Figure 4 ,and Figures 1 to 3 The difference between the first display device in the embodiment is that the first inner wall bending surface and the second inner wall bending surface are both planes, wherein the non-common edges of the first inner wall bending surface and the non-common edges of the second inner wall bending surface can be straight line segments. In this case, a plurality of the first inner wall bending surfaces and the second inner wall bending surfaces are arranged in an interlaced manner to form a surrounding sawtooth shape 41. The first outer wall bending surface corresponding to the first inner wall bending surface and the second outer wall bending surface corresponding to the second inner wall bending surface can still be curved surfaces.

[0057] Figure 5 A cross-sectional view showing a second display device according to an embodiment of the present application.

[0058] and Figure 2 Similar, along Figure 4 A cross section is performed at a fixed position in the display device to obtain a cross-sectional view of the display device from a top view. Figure 5 In, with Figure 2 The difference is, Figure 5 The flexible display panel 51 and the inner wall 52 can both be set to a sawtooth shape, while the side of the outer wall 53 facing the inner wall 52 can still maintain a wavy shape, and the second outer wall 533 on the other side can be a curved surface.

[0059] See also Figure 5The flexible display panel 51 includes a first panel bending surface 511 and a second panel bending surface 512, and the inner wall 52 includes a first inner wall bending surface 521 and a second inner wall bending surface 522. The flexible display panel 51 and the inner wall 52 have the same direction. The outer wall 53 includes a first outer wall bending surface 531 and a second outer wall bending surface 532. The first outer wall bending surface 531, the second outer wall bending surface 532, the first inner wall bending surface 521 and the second inner wall bending surface 522 enclose a sandwich, one side of which is formed based on a curved surface, and the other side is formed based on a flat surface. The sandwich can also be unfilled or filled with a transparent material.

[0060] like Figure 5 As shown, a plurality of light-emitting components may be provided in the flexible display panel 51, and the plurality of light-emitting components are respectively provided on the plurality of panel bending portions. The light-emitting components may be light-emitting devices such as LEDs. For example, the light path emitted by the light-emitting component B1 may vertically pass through the second inner wall bending surface 522 to reach the interlayer, and then be reflected by the second outer wall bending surface to become a divergent light path. After the divergent light path reaches the second outer wall 533, the light path is refracted into a vertically upward parallel light L1.

[0061] In addition, the present application also provides a display terminal, which includes the display device. The display terminal may include a vehicle-mounted device, a mobile phone, a notebook, a tablet, a commercial advertising device, a wearable device display device, a portable display device, etc. It can be understood that the present application does not limit the display terminal.

[0062] In summary, compared to the flat lamination and splicing screens in the prior art, the present application can not only display normally on the flat part of the "bottle cap", but also display the picture on the side part of the "bottle cap", thus realizing the design of a full curved screen. Since the full curved screen requires curved lamination, there may be wrinkle problems, so the present application can improve the wrinkle problem by designing a zigzag lamination. In addition, the present application can improve the wrinkle problem of the flexible display panel lamination by providing a plurality of outer wall bending portions arranged opposite to the inner wall on the outer wall of the cover plate, and making the bending direction of each inner wall bending portion opposite to the bending direction of the outer wall bending portion corresponding to the inner wall bending portion, thereby optimizing the optical path, realizing a full curved screen with multi-directional display, and improving the display effect.

[0063] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0064] The display device and display terminal provided in the embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application.
