TECHNICAL FIELD

[0001] The present application relates to the display field, and in particular to a display device and electronic equipment. BACKGROUND

[0002] At present, in order to improve the screen ratio of a mobile phone screen, a front camera is usually placed under the screen, and a circular hole is cut in the film material under the cover plate glass of the screen module at the lens of the front camera to ensure that light is captured by the camera through the cover plate glass. A circular ink is printed on the cover plate glass to cover the circular cutting edge of the film material under the cover plate glass.

[0003] In the research and practice of the prior art, the inventors of the present application found that for the flexible OLED module matched on the flexible OLED foldable mobile phone, since the multiple film layers are attached by optical glue with extremely low modulus, a certain slip dislocation occurs between the film layers during the folding process, which causes the ink to shift together, and further causes the camera area to block the collection of external light, which completely affects the normal use of the camera. SUMMARY

[0004] The purpose of the present application is to provide a display device and electronic equipment, which can solve the technical problem of poor light collection of the camera area caused by the displacement of the film layer during the folding process of the existing foldable under-screen camera.

[0005] To achieve the above-mentioned purpose, the present application provides a display device, comprising a flexible screen and a camera; the flexible screen comprises a camera area and a non-camera area; the camera area is a hole structure, the hole structure has a first aperture and a second aperture, the first aperture and the second aperture are not the same; the camera is nested in the hole structure.

[0006] Further, the first aperture is the maximum aperture, and the second aperture is the minimum aperture; the flexible screen is a multi-film layer structure, and the multi-film layer structure will move when the flexible screen is folded; the direction of the movement of the multi-film layer structure is defined as the first direction, and the first aperture is the inner diameter of the hole structure in the first direction; the direction perpendicular to the first direction is defined as the second direction, and the second aperture is the inner diameter of the hole structure in the second direction.

[0007] Further, the difference between the first aperture and the second aperture is less than 1mm.

[0008] Further, an ink layer is provided at the edge of the hole structure

[0009] Further, in the first direction, distances from two side walls of the hole-shaped structure to a straight line where the central axis of the camera is located are defined as a first distance and a second distance respectively, and the first distance and the second distance are not equal.

[0010] Further, a difference between the first distance and the second distance is less than 1 millimeter.

[0011] Further, a shape of a cross section of the hole-shaped structure is any one of an oval shape and a rounded rectangular shape.

[0012] Further, the flexible screen comprises a support plate, a back plate attached to a side of the support plate away from the camera, a display panel attached to a side of the back plate away from the support plate, a polarizer attached to a side of the display panel away from the back plate, and a cover plate attached to a side of the polarizer away from the display panel.

[0013] Further, the hole-shaped structure penetrates the support plate, the back plate, the display panel and the polarizer in sequence.

[0014] To achieve the above object, the application further provides an electronic device comprising the display device as described above.

[0015] The technical effect of the application is that the camera area opening of the under-screen camera is non-circular, and in the folding process, the inner diameter of the hole-shaped structure in the direction of the displacement of the film layer structure is greater than the inner diameter in the direction perpendicular to the displacement direction, which does not block the external light from entering the camera area, ensuring the light collection capability of the camera area. The under-screen camera display device ensures the light collection capability of the camera at multiple angles while improving the screen-to-body ratio. BRIEF DESCRIPTION OF DRAWINGS

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower of the device in the actual use or working state, and specifically refer to the direction of the drawing surface in the drawings; and "inner" and "outer" refer to the contour of the device.

[0027] The present application provides a display device and an electronic device. The following are described in detail. It should be noted that the order of the following embodiments is not limited as the preferred order of the embodiments.

[0028] As shown in Figure 1 , Figure 2 The present application provides a display device 100, which has a camera area 110 and a non-camera area 120, and the non-camera area 120 is arranged around the camera area 110. The display device 100 includes a flexible screen 1 and a camera 2.

[0029] The camera area 110 is a hole-shaped structure, that is, a through hole. The shape of the hole-shaped structure is not circular, and the cross section is a non-circular structure, including an elliptical shape, a rounded rectangular shape, a goose egg shape, etc. In the present embodiment, an elliptical cross section is taken as an example for further description. Because the cross section is not circular, it must have multiple different sizes of inner diameter. The maximum aperture is defined as the first aperture 10, and the minimum aperture is defined as the second aperture 20. The first aperture 10 is not the same as the second aperture 20, the length of the first aperture 10 is greater than the length of the second aperture 20, and the length difference between the first aperture 10 and the second aperture 20 is not more than 1 millimeter.

[0030] In the process of bending, the multi-film layer structure is displaced, and the non-circular camera area 110 does not block the light from the outside from passing through the camera area 110, so that the camera area 110 can normally collect the light from the outside and ensure the camera effect.

[0031] The flexible screen 1 is a multi-film layer structure. Because of the existence of the hole structure, in the process of bending, the multi-film layer structure will inevitably have the phenomenon of film layer movement, and the film layer movement is generally horizontal movement. In this embodiment, the direction of the multi-film layer movement is defined as the first direction X, and the direction perpendicular to the first direction is the second direction Y. The first aperture 10 is an aperture in the first direction X, and the second aperture 20 is an aperture in the second direction Y.

[0032] The flexible screen 1 includes a support plate 11, a back plate 12, a display panel 13, a polarizer 14, a cover plate 15, and ink 16.

[0033] The support plate 11 plays a supporting role and is attached to the upper surface of the camera by optical glue.

[0034] The back plate 12 is attached to the side of the support plate 11 away from the camera by optical glue. In this embodiment, the back plate 12 is attached to the upper surface of the support plate 11.

[0035] The display panel 13 is attached to the side of the back plate 12 away from the support plate 11 by optical glue. In this embodiment, the display panel 13 is attached to the upper surface of the back plate 12, and the display panel 13 is used to realize the display function.

[0036] The polarizer 14 is attached to the side of the display panel 13 away from the back plate 12 by optical glue. In this embodiment, the polarizer 14 is attached to the upper surface of the display panel 13. The polarizer 14 is used to uniformly emit the light emitted from the display panel 13 to the outside.

[0037] The cover plate 15 is attached to the side of the polarizer 14 away from the display panel 13 by optical glue. In this embodiment, the cover plate 15 is attached to the upper surface of the polarizer 14. The cover plate 15 plays a role of protecting the display panel and preventing it from being rubbed and scratched by the outside. The cover plate 15 is generally a glass cover plate and does not affect the input of light from the outside.

[0038] The ink 16 is arranged on the cover plate 15 in a ring shape and around the camera area 110, that is, at the boundary of the camera area 110. The ink 16 prevents light from entering the non-camera area 120 and affecting the normal use, and also collects more light in the camera area 110 to improve the light collection capability of the camera area 110.

[0039] The ink 16 can also be arranged at any position in the multi-film layer structure in other embodiments as long as it is arranged around the hole structure to prevent light from entering the non-camera area 120.

[0040] The camera 2 is nested in the hole structure, the camera 2 is in a boss shape, the support plate 11 is arranged on the plane of the camera 2, and the lens protrusion is embedded in the hole structure, specifically, the lens protrusion is embedded in the support plate 11 and the back plate 12, and the lens mainly realizes the light collection effect.

[0041] The hole structure sequentially penetrates the support plate 11, the back plate 12, the display panel 13, and the polarizing plate 14, and does not penetrate the cover plate 15. The completely penetrating hole structure design makes light only propagate in air medium, reduces light loss as much as possible, and improves light transmittance.

[0042] The central axis of the hole structure is not in line with the central axis of the camera 2, so the distances from the two side walls of the hole structure to the straight line where the central axis of the camera 2 is located are defined as the first distance D1 and the second distance D2, respectively. The first distance D1 and the second distance D2 are not equal, and the difference between the first distance D1 and the second distance D2 is less than 1 mm.

[0043] The display device 100 of the embodiment can be applied to an inner folding or outer folding display device. The difference between the inner folding display device and the outer folding display device is that the displacement direction of the multi-film layer structure is opposite, and the remaining features are the same, which will not be described in detail here.

[0044] The technical effect of the display device of the embodiment is that the camera area aperture for under-screen camera is non-circular. In the folding process, the inner diameter in the displacement direction of the film layer structure is greater than the inner diameter in the direction perpendicular to the displacement direction, which does not shield external light from entering the camera area, and ensures the light collection capability of the camera area. The under-screen camera display device ensures the light collection capability of the camera at multiple angles while improving the screen ratio.

[0045] The embodiment also provides an electronic device, which comprises the display device as described above, and is generally a mobile phone, a tablet, a flexible display device, or a liquid crystal display, and has great market value at present.

[0046] The display device and the electronic device provided by the embodiment of the application are described in detail above, and the principle and implementation manner of the application are described by using specific examples in this paper, and the above embodiment is only used to help understand the method and the core idea of the application; meanwhile, for those skilled in the art, the specific implementation manner and the application range can be changed according to the idea of the application, and the above description should not be understood as a limitation on the application.
