The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

The present embodiment provides an electronic device. The electronic equipment can be mobile phones, computer screens, IPADs, telephone watches and other electronic equipment with shooting and displaying functions. The specific form of the electronic apparatus is not limited herein as long as the electronic apparatus has the front photographing and displaying function. Specifically, in the present application, the electronic device is described by taking the mobile phone 10 as an example.

Referring to fig. 1 and fig. 2, in the present embodiment, an electronic device 10 may include a cover plate 11, a display 12, a camera assembly 13 and a lens 14.

Referring to fig. 2, the cover 11 is used for finger touch contact, and the cover 11 is located at the outermost side of the electronic device 10. The cover 11 may be a transparent cover 11 of glass, resin, or the like. A groove 111 is formed on one side surface of the cover plate 11 facing the display screen 12. The depth of the groove 111 is smaller than the thickness of the cover plate 11, so that the other side surface of the cover plate 11 is a smooth plane, and the touch operation of an operator on the cover plate 11 is not affected.

The groove 111 is a circular groove 111. In other embodiments, the groove 111 may also be a square groove, an oval groove, etc., and the shape of the groove 111 is not limited herein.

The display screen 12 is used to display images. The display 12 may be an LED display, an OLED display, an LCD display, etc., and the type of the display 12 is not limited herein. The display 12 includes a plurality of pixels that emit light to form an image. The display screen 12 is provided with a through hole 121, and the through hole 121 is disposed opposite to the groove 111.

The shape of the through-hole 121 is adapted to the shape of the groove 111. When the groove 111 is a circular groove, the through-hole 121 is a circular through-hole 121. The shape of the through hole 121 is not limited, and in other embodiments, the through hole 121 may be designed as a square through hole, an oval through hole, or the like.

The opening position of the through hole 121 is opposite to the opening position of the groove 111. And, the central axis of the through-hole 121 coincides with the central axis of the groove 111.

The aperture of the through hole 121 is smaller than the notch aperture of the groove 111. The aperture size of the through-hole 121 corresponds to the black border area of the through-hole 121.

At present, in traditional electronic equipment, often reduce the black border region of through-hole through the black border that reduces the size of the subassembly of making a video recording and display screen, not only influence the subassembly effect of shooing, also can increase electronic equipment's cost simultaneously. Moreover, the black edge area of the through hole can be only small and can not be completely eliminated.

The display 12 includes a primary display area 122 and a non-primary display area 123. The main display area 122 is located in the middle of the display screen 12. The non-main display area 123 is located at an edge position of the display screen 12. For example, the edge position may be a side position, a top corner position, etc. of the display screen 12. The through hole 121 is opened at the edge of the display 12 and located in the non-main display area 123 of the display 12. Because the through hole 121 does not have a touch function, the through hole 121 is opened at the edge of the display screen 12, so that the main display area 122 of the display screen 12 can be ensured to have the stability of the touch function. In addition, the black edge area of the through hole 121 located at the edge of the display 12 does not affect the overall display effect of the display 12, and the visual effect of the black edge area is reduced as much as possible.

The camera assembly 13 is used to take images. The camera assembly 13 is disposed opposite the through hole 121. The camera module 13 includes a base 131 and a lens 132. The base 131 is used for carrying the lens 132, and the lens 132 is disposed on the base 131. The lens 132 is used for taking light and images. In this embodiment, the camera assembly is a front camera.

The camera assembly 13 is disposed on a side of the cover plate 11 facing the display 12. Wherein, the base 131 is located on a side of the display 12 opposite to the cover plate 11. The lens 132 can be accommodated in the through hole 121, so that the space occupied by the camera module 13 in the thickness direction of the electronic device 10 is reduced, and the electronic device 10 is light, thin and light.

The display screen 12 faces away from the cover plate 11, and the inner side wall of the through hole 121 is provided with an avoiding part 124. The relief portion 124 has a stepped structure. The escape portion 124 is used to escape the imaging module 13. The escape portion 124 can prevent the base 131 from colliding or rubbing against the display 12 when the camera module 13 is installed, so as to prevent the display 12 from being damaged.

The lens 14 is accommodated in the groove 111. The lens 14 is used for refracting the emergent rays of the display screen 12, and the emergent rays are refracted and converged by the lens 14. The lens 14 is accommodated in the groove 111, and the outer periphery of the lens 14 is overlapped on the display screen 12. The light emitted from the display 12 is projected onto the lens 14, and the light is refracted by the lens 14 and converged toward the central axis of the lens 14 according to the principle of light refraction. The observer is located on the side of the cover plate 11 opposite to the display 12, and the diameter of the through hole 121 located on the display 12 is smaller than the actual diameter of the through hole 121.

The lens 14 and the groove 111 may be adapted. The size of the lens 14 is just accommodated in the groove 111, so that the problem that the cross-sectional area of the groove 111 is large and the strength of the cover plate 11 is affected due to the overlarge size of the groove 111 is avoided.

The gap between the lens 14 and the inner side wall of the groove 111 is filled with optical cement. The lens 14 is fixed in the groove 111 through optical cement, and the position stability of the lens 14 is ensured. It can be understood that the optical adhesive may be a transparent adhesive or the like to enhance the light exiting effect, and prevent a gap from existing between the lens 14 and the groove 111 of the cover plate 11, which affects the uniform light exiting.

Referring to fig. 3, the lens 14 includes a convex portion 141 and a ring portion 142 disposed around the convex portion 141. The convex portion 141 is opposite to the lens 132 of the image pickup unit 13, and the convex portion 141 is used to condense light rays entering the lens 132. The convex portion 141 can condense light entering the lens 14 from the outside of the cover plate 11, and thus light entering the lens 132 of the image pickup unit 13 can also be condensed. The shooting angle of view of the camera assembly 13 can be relatively increased. On one hand, the incident angle of the incident light of the camera assembly 13 is increased, so that the shooting visual angle can be increased; on the other hand, for the electronic device with the same shooting quality requirement, the lens 14 with the convex part 141 can correspondingly reduce the opening size of the through hole 121, and the screen occupation ratio of the display screen can be improved.

The lens 132 of the image pickup unit 13 is positioned at the focal point of the convex portion 141, so that the captured image is made clear, and the image pickup effect of the image pickup unit 13 is improved. It is understood that in other embodiments, if the focal length of the protruding portion 141 is larger than the depth of the through hole 121, the lens 132 of the camera module 13 may also be located outside the through hole 121, so as to ensure that the camera module 13 has a better shooting effect.

Referring to fig. 4, in the present embodiment, the protrusion 141 includes two arc surfaces disposed opposite to each other. For convenience of illustration, it is now provided that the two curved surfaces of the convex portion 141 may include a first curved surface 1411 and a second curved surface 1412, and a side surface of the convex portion 141 facing the lens 132 is the first curved surface 1411, and the other side surface is the second curved surface 1412.

Accordingly, the convex portion 141 is a convex lens. The shape and structure of the convex lens are more standard, so that parameters such as a focus, a focal length and the like can be conveniently calculated, and the selection and arrangement position of the lens 132 of the camera component 13 can be conveniently selected.

It is understood that in other embodiments, the first arc surface and the second arc surface of the convex portion may also include a polygonal surface structure formed by splicing a plurality of planes. The specific shape of the projection is not limited herein.

The ring portion 142 is used for converging the emergent light of the display screen 12. The ring portion 142 is used for overlapping the display screen 12, so that the image display light emitted by the display screen 12 can be refracted by the ring portion 142 and then emitted into the human eye through the cover plate 11. The ring portion 142 may converge light emitted from the display 12.

Specifically, in the present embodiment, the thickness of the ring portion 142 gradually decreases from the inside to the outside in the radial direction of the ring portion 142. According to the refraction principle of the prism, the refracted light rays are refracted towards the thick edge direction of the prism. Therefore, the light passing through the ring portion 142 can be refracted toward the side of the ring portion 142 where the thickness is large. The side of the ring portion 142 with the larger thickness is close to the middle of the lens 14, so that the light refracted by the ring portion 142 is refracted towards the central axis direction of the lens 14, that is, the purpose of converging the emergent light beam of the display screen 12 is achieved. The route of the emergent light of the display screen 12 is changed through the refraction of the lens 14, so that the emergent light of the display screen 12 is refracted towards the direction of the central axis of the through hole 121, the black edge area of the corresponding position of the through hole 121 is reduced when the display screen displays, and the screen occupation ratio of the display screen 12 of the whole machine is improved.

In the present embodiment, the ring portion 142 includes two side surfaces that are inclined to each other. For convenience of illustration, it is provided that the two sides of the ring portion 142 may include a first side 1421 and a second side 1422, and the side of the protrusion 141 facing the lens 132 is the first side 1421, and the other side is the second side 1422.

Specifically, the first side 1421 and the second side 1422 are planar. The incident angle and the emergent angle of the emergent ray of the display 12, i.e. the included angle between the emergent ray of the display 12 and the first side surface 1421 and the included angle between the emergent ray and the second side surface 1422, are easy to calculate and measure. Therefore, the lens 14 is convenient to manufacture, measure and operate a simulation experiment.

Referring to fig. 5, in the present embodiment, an included angle between the first side surface 1421 and the second side surface 1422 of the ring portion 142 is e, and the included angle e should be increased as much as possible. Since the included angle e is increased and the refraction angle f is larger than the included angle e, the refraction angle f is also increased correspondingly. Since the periphery of the display 12 needs to be provided with a black edge forming the display by passing wires, the emergent light at the position a of the display 12 closest to the through hole 121 enters the lens 14 and is refracted by the lens 14 and emitted from one side of the cover plate 11. The light is transmitted from a position b from the central axis of the through-hole 121. Therefore, the black edge area of the corresponding position of the through hole 121 is reduced when the display screen displays, and the screen occupation ratio of the whole display screen 12 is improved.

Specifically, in this embodiment, the b position can be located the axis position of through-hole 121, then the axis position department that light refracted to through-hole 121 jets out, then the emergent ray of display screen 12 is refracted through lens 14, can be closer to the axis of through-hole 121, then the emergent ray of display screen 12 that is located through-hole 121 all around converges towards the axis of through-hole 121 through lens 14 refraction, then the emergent ray of display screen 12 has all been refracted in the former black border region of through-hole 121, consequently, there is not the black border region in this through-hole 121 department, thereby reach the full screen display, improve the screen of complete machine display screen 12 and account for the ratio.

The two side surfaces of the lens 14 may be symmetrically or asymmetrically arranged. Specifically, in the present embodiment, referring to fig. 4, the first cambered surface 1411 and the second cambered surface 1412 of the convex portion 141 are symmetrically disposed with respect to a cross-section g-g passing through the center point of the lens 14. The first side 1421 and the second side 1422 of the ring portion 142 are symmetrically disposed with respect to each other about a cross-section g-g through the center point of the lens 14.

Referring to fig. 6, it can be understood that, in other embodiments, the first side surface 2421 of the lens 24 and the light emitting surface of the display screen 12 are parallel to each other. On one hand, the lens 24 can be stably lapped on the display screen 12; on the other hand, the emergent light of the display 12 can be vertically incident into the lens 24, and the incident angle of the incident lens 24 is zero, when the light is refracted in the lens 24, the incident angle of the light is the included angle e between the first side surface and the second side surface, and the incident angle is larger. Since the refraction angle f of the light is larger than the incident angle e, the corresponding refraction angle f is also increased if the incident angle is larger. The emergent light with a larger refraction angle f can converge and approach the light towards the central axis direction of the through hole as much as possible, and the screen occupation ratio of the display screen 12 is increased.

It is understood that, in other embodiments, the first arc surface 2411 and the second arc surface 2412 of the convex portion 241 may be asymmetrically arranged. The first side surface 2421 and the second side surface 2422 of the ring part 242 may be asymmetrically arranged. The first cambered surface 2411 and the second cambered surface 2412 of the convex part 241 can adjust the size of the refraction angle f of the refracted light rays by adjusting the inclination angles of the first side surface 2421 and the second side surface 2422.

It is understood that, in other embodiments, the first side surface and the second side surface of the ring portion may also be two cambered surfaces. The cambered surface of the ring part and the cambered surface of the convex part can also be positioned on the same cambered surface.

Specifically, in the present embodiment, the ring portion 142 and the protruding portion 141 have a smooth transition therebetween. The first side surface 1421 and the second side surface 1422 of the ring portion 142 are smoothly transited to the first cambered surface 1411 and the second cambered surface 1412 of the protrusion 141. The plane of the ring part 142 may be tangent to the arc surface of the convex part 141, so as to ensure a smooth transition at the boundary between the ring part 142 and the convex part 141. The ring portion 142 and the convex portion 141 are in smooth transition, so that the light rays at the junction of the ring portion 142 and the convex portion 141 can be prevented from being staggered and interfering with each other, and the light rays are not uniform to influence the visual effect of the through hole 121.

The lens 14 of the electronic device 10 utilizes the prism refraction principle, the groove 111 is formed in the cover plate 11 on the black edge area of the through hole 121, and the lens 14 capable of changing light rays is assembled in the groove 111, so that the emergent light rays of the display area of the display screen 12 are refracted on the black edge area of the through hole 121, and the effect of visually displaying the whole screen is achieved.

Meanwhile, in the area of the forward photographing visual angle, the lens 14 is in a convex lens shape so as to increase the range of the photographing visual angle of the camera shooting assembly.

Therefore, the electronic device 10 realizes a full-screen, has a simple structural form, has universality for the through-hole screen, has obvious cost advantage, and has good overall reliability of the electronic device 10. The overall screen display of the electronic device 10 has wide applicability, is not limited by the size of the camera module 13 and the size of the black edge of the display screen 12, and improves the expressive force of the product without increasing the cost.
