Please refer to fig. 1, which discloses a schematic structural diagram of an electronic device according to an embodiment of the present application. The electronic device 100 may include a function 200 and a non-display area 400 and a display area 600. Specifically, the non-display area 400 and the display area 600 may constitute a display screen for displaying an image. The non-display area 400 may include a first non-display area 401 and a second non-display area 402. The first non-display region 401 may surround the display region 600, and of course, the first non-display region 401 may also be disposed on one side or both sides of the display region 600. The display area 600 may be surrounded at the periphery of the second non-display area 402. The function piece 200 is installed in the second non-display area 402. The functional element 200 may be a button for operating the electronic device 100. This function piece 200 can be the module of making a video recording to be used for making a video recording, take a picture. The functional element 200 may be a flash assembly for assisting in taking a picture and taking a photograph. The functional element 200 may be a device for warning and reminding, such as an LED lamp and a breathing lamp. Of course, the function 200 may also be other elements such as a microphone, a sound, a data interface, etc. The electronic device 100 may be specifically a mobile phone, a tablet computer, a notebook computer, an intelligent bracelet, an intelligent watch, an intelligent helmet, an intelligent glasses, an augmented reality/virtual reality device (e.g., augmented reality glasses, virtual reality glasses), a display (e.g., a liquid crystal display), and the like. The specific form of the electronic device 100 may also be other electronic devices with a display and the function element 200, and is not limited herein. In the embodiment of the present application, the functional component 200 is used as a camera module for taking a picture and taking a picture as an example for explanation.
It is to be noted that the terms "first", "second", etc. are used herein and hereinafter for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features.
For the above and below-described names, "first non-display area", "second non-display area", and "non-display area" may be mutually converted, for example, "first non-display area" may also be referred to as "second non-display area", and may also be referred to as "non-display area".
Referring to fig. 1, a camera hole a may be disposed in the second non-display area 402, and the camera hole a may be a circular through hole. The camera hole a is used for installing the functional part 200 for shooting and taking pictures. The part of the second non-display area 402 arranged around the camera hole a can be used for shielding the light leakage of the display area 600 around the camera hole a, so as to realize the function of camera shooting under the screen and ensure the imaging quality.
The function element 200 is a camera module. The camera module can be a periscopic long-focus camera or a wide-angle camera or a large wide-angle camera. Specifically, compared to a vertical lens, the periscopic telephoto camera can reduce the requirement for the height of the camera by changing the propagation path of light, and thus can reduce the overall thickness of the electronic device 100. The field angle of the periscopic long-focus camera can be within 10-30 degrees, the focal length of the periscopic long-focus camera is large, and the periscopic long-focus camera is generally used for shooting a long shot so as to obtain a clear image of the long shot. The vertical lens refers to a lens with a straight optical axis, such as a wide-angle camera and a large wide-angle camera. The wide-angle camera has the advantages of being high in pixel and large in pixel point, is used for non-distant view or close view, and can normally shoot objects, and the field angle of the wide-angle camera is a common field angle which is within the range of 80-110 degrees. The field angle of the large wide-angle camera is an ultra-wide angle, is in the range of 110-130 degrees, is used for wide-angle shooting, and is favorable for improving the optical zoom multiple. The field angle of the large wide-angle camera is large, and correspondingly, the focal length of the large wide-angle camera is short, so that the large wide-angle camera is generally used for shooting a close shot, and a local close-up image of an object is obtained. In one embodiment, the camera hole a may be plural so as to mount plural cameras. For example, 3 cameras are installed, and the first camera is a periscopic telephoto camera with an angle of view of 10 degrees, 12 degrees, 15 degrees, 20 degrees, 26 degrees, or 30 degrees. The second camera is a large wide-angle camera, and the angle of view of the second camera is 110 degrees, 112 degrees, 118 degrees, 120 degrees, 125 degrees or 130 degrees. The third camera is a wide-angle camera, and the angle of view of the third camera is 80 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees or 110 degrees and the like.
Referring to fig. 2, a schematic structural diagram of an electronic device 100 according to another embodiment of the present application is disclosed, in which a first non-display area 401 is surrounded on the periphery of a display area 600. The second non-display area 402 is disposed between the first non-display area 401 and the display area 600. The display area 600 semi-surrounds the second non-display area 402. The imaging aperture a is provided in the first non-display area 401 and the second non-display area 402. The portion of the second non-display area 402 half-surrounded by the display area 600 may be used to block light leakage of the display area 600 around the camera hole a. Under the condition of possessing the functional piece 200, the size occupation ratio of the first non-display area 401 at the outermost periphery of the electronic device 100 is favorably reduced, the screen occupation ratio of the electronic device 100 is favorably improved, and the visual effect of a large screen is given to a user.
It should be noted that fig. 1 and 2 only illustrate the shapes and positions of the non-display area 400 and the display area 600 by way of example, and do not limit the present invention. For example, the second non-display area 402 is disposed at a position above the center of the electronic device 100 in fig. 1 and 2. Referring to fig. 3, a schematic structural diagram of an electronic device 100 according to another embodiment of the present application is disclosed. The second non-display area 402 is disposed at a position above and to the left of the midpoint of the electronic device 100. The first non-display area 401 surrounds the display area 600, and the display area 600 surrounds the second non-display area 402. A camera hole a can be arranged in the second non-display area 402, and the camera hole a is used for installing the functional piece 200 for shooting and taking pictures. The portion of the second non-display area 402 disposed around the camera hole a may be used to block light leakage of the display area 600 around the camera hole a. The functional element 200 is disposed in the second non-display area 402 and is not disposed in the first non-display area 401, so that the area of the first non-display area 401 can be reduced without being affected by the functional element 200. The reduced range of the first non-display area 401 is beneficial to improving the screen occupation ratio of the electronic device 100, and gives a visual effect of a large screen to a user.
It will be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," and the like, as used herein, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present application.
Referring to FIG. 4, a partial cross-sectional view of section B-B of FIG. 3 is disclosed. The electronic device 100 may include a function element 200, a display module 300 and a backlight module 500. Specifically, the display module 300 is located at the light emitting side of the backlight module 500, and the display module 300 and the backlight module 500 can be fixed together in a stacked manner, for example, by gluing, and the backlight module 500 is provided with a camera hole a for installing the functional component 200. The backlight module 500 is provided with a light shielding area around the camera hole a, and the light shielding area is used for shielding light leakage of the backlight module 500 around the camera hole a.
In an embodiment, referring to fig. 4, the display module 300 may include a cover plate 10, a first polarizer 20, a first glass substrate 30, a second glass substrate 40, and a second polarizer 50, which are sequentially stacked. The cover plate 10, the first polarizer 20, the first glass substrate 30, the second glass substrate 40 and the second polarizer 50 are fixed together, for example by gluing.
For the designations above and below, "first polarizer", "second polarizer", and "polarizer" may be interchanged, for example, "first polarizer" may also be referred to as "second polarizer" and may also be referred to as "polarizer".
For the above and below described names, "first glass substrate", "second glass substrate", and "glass substrate" may be interchanged, for example, "first glass substrate" may also be referred to as "second glass substrate" and may also be referred to as "glass substrate".
Specifically, a plurality of grid-shaped transparent metal film wires which are arranged horizontally and vertically and are insulated from each other are distributed on the second glass substrate 40, and the second glass substrate 40 is divided into a plurality of tiny grids which are called as primary color units; and in each cell there is a transparent metal film electrode insulated from the surrounding wires, called a pixel electrode. One corner of the electrode is connected to two vertical and horizontal wires by a thin Film transistor (tft) (thin Film transistor) formed on the second glass substrate 40 by printing. The first glass substrate 30 is also divided into a plurality of small cells each corresponding to one pixel electrode of the second glass substrate 40, but with the difference that it has no separate electrode and is covered with only a small piece of red, blue, green transparent thin film filter, and the entire first glass substrate 30 is uniformly covered with only one transparent conductive film called a common electrode. A small capacitor is formed between the common electrode and each pixel electrode of the second glass substrate 40, so that when a voltage is applied to the horizontal and vertical lines to select the thin film transistor, the transistor is conductive, the capacitors of the pixel electrode and the common electrode are charged, an electric field acting on liquid crystal molecules between the first glass substrate 30 and the second glass substrate 40 is formed, the electrode area of the pixel becomes transparent, and the transparent area can respectively display different colors of red, blue and green due to different colors of the covered red, green and blue filters, thereby forming a primary color pixel of color display. The first glass substrate 30 and the second glass substrate 40 may also be referred to as "TFT glass substrates", respectively. And a liquid crystal cell may be formed between the first glass substrate 30 and the second glass substrate 40 to be filled with liquid crystal (not shown).
In one embodiment, the polarization direction of the first polarizer 20 is different from the polarization direction of the second polarizer 50 by 90 °. The backlight module 500 emits white light from one side of the second polarizer 50, and the white light is emitted into the second polarizer 50, the second polarizer 50 can change the polarization direction of the white light, and the white light is emitted into the first glass substrate 30 and the second glass substrate 40, and liquid crystal molecules are regularly arranged under the action of a driving circuit between the first glass substrate 30 and the second glass substrate 40, so that the polarization direction of the white light is rotated by 90 degrees, and the polarization direction of the first polarizer 20 is 90 degrees different from that of the second polarizer 50, so that the light passes through the first polarizer 20; the liquid crystal molecules are arranged disorderly when not acted by the driving circuit between the first glass substrate 30 and the second glass substrate 40, so that the polarization direction of the white light cannot rotate by 90 degrees, and the polarization direction of the first polarizer 20 is different from that of the second polarizer 50 by 90 degrees, so that light cannot pass through the first polarizer 20; the purpose of displaying color images is achieved by the action of the driving circuit between the first glass substrate 30 and the second glass substrate 40 on the liquid crystal molecules.
In one embodiment, the cover plate 10 covers the first polarizer 20 for protecting the display module 300. The cover plate 10 may be made of a material having good light transmittance, such as glass or plastic. In one embodiment, the cover plate 10 may be connected to the first polarizer 20 through a transparent optical Clear adhesive (oca) 60; the cover plate 10 is fixed on the first glass substrate 30 by the transparent optical OCA glue 60, so that the cover plate 10 is prevented from moving when the electronic device 100 vibrates. In one embodiment, the cover plate 10 may be omitted.
In one embodiment, the first polarizer 20 is provided with a through hole C near the orthographic projection area of the first polarizer 20 of the camera hole a, and the through hole C may be circular; the camera hole a may enclose a through hole C around the orthographic projection area of the first polarizer 20, that is, the area of the through hole C is larger than that of the camera hole a in the orthographic projection area of the first polarizer 20. The through hole C prevents the light from being interfered by the first polarizer 20 and entering the camera hole a smoothly.
In an embodiment, the camera hole a is provided with black silk-screen printing ink 70 between the first glass substrate 30 and the second glass substrate 40, i.e. near the edge of the orthographic projection area of the liquid crystal chamber, so as to prevent light from entering the camera hole a from the area between the first glass substrate 30 and the second glass substrate 40 in the operating state of the display module 300, which causes light leakage in the camera hole a. The black screen printing ink 70 may be specifically prepared by screen printing with black ink to form a black screen printing coating.
In one embodiment, a region D (also referred to as a "light incident region D") surrounded by the black screen printing ink 70 between the first glass substrate 30 and the second glass substrate 40 may be surrounded by the periphery of the orthographic projection region of the imaging hole a in the liquid crystal chamber. And the area D surrounded by the black silk-screen printing ink 70 between the first glass substrate 30 and the second glass substrate 40 is not filled with liquid crystal, so that light can pass through the orthographic projection area of the liquid crystal chamber from the camera hole a without being influenced by the liquid crystal. Referring to fig. 4, a region D surrounded by the black screen printing ink 70 and the camera hole a define a light incident region E. The light incident area E may be transparent for transmitting external light to facilitate imaging of the functional element 200. The display area corresponding to the camera angle of the functional component 200 is the light incident area E, and of course, the display area corresponding to the camera angle of the functional component 200 may also be located inside the light incident area D.
In an embodiment, the second polarizer 50 is provided with a through hole near the orthographic projection area of the first polarizer 20 of the camera hole a to match with the backlight module 500 for sealing and shading, so that light can pass through the camera hole a smoothly without being affected by the first polarizer 20, and light leakage of the camera hole a caused by the light entering the camera hole a from the area between the second polarizer 50 and the backlight module 500 is avoided. The through hole in which the second polarizer 50 is disposed may be circular. In addition, when the second polarizer 50 is stacked and adhered to the second glass substrate 40, the through hole of the second polarizer 50 may form a blind hole.
Referring to fig. 4, the backlight module 500 is used for Emitting white Light, and may use a Light-Emitting Diode (LED) backlight to emit uniform backlight, so as to improve the display effect of the electronic device 100. The white light LED backlight source has low power consumption, the RGB-LED backlight source can effectively improve the contrast of the display, realize more accurate color gradation and pictures with stronger layering sense, and ensure that the liquid crystal display has lighter weight and thinner thickness.
Referring to fig. 4, the backlight module 500 may include an optical film assembly 80 and a back plate module 90. Specifically, the backplane module 90 is used for carrying the optical film assembly 80 and the display module 300. The back plate module 90 is provided with a through hole a, which may be circular. The optical film assembly 80 is mounted on the backplane module 90, and a through hole is formed in the orthographic projection range of the through hole a on the optical film assembly 80 so as to give way to the backplane module 90 and the functional component 200.
Referring to fig. 4 and 5, fig. 5 discloses a schematic structural diagram of a portion F of the structure in fig. 4. The optical film assembly 80 can emit uniform backlight to enable the electronic device 100 to operate normally. The optical film set 80 may include a first light intensifying sheet 81, a second light intensifying sheet 82, a diffusion sheet 83, a light guide plate 84, and a reflection sheet 85. Specifically, the first brightness enhancement film 81, the second brightness enhancement film 82, the diffusion film 83, the light guide plate 84 and the reflection film 85 are sequentially stacked, light emitted from the light source enters the light guide plate 84, and the light sequentially passes through the light guide plate 84, the diffusion film 83, the second brightness enhancement film 82 and the first brightness enhancement film 81 and then enters the display module 300, such as the second polarizer 50.
The first light intensifying plate 81, the second light intensifying plate 82 and the diffusion plate 83 can constitute an optical film (also called as "light homogenizing element"). Specifically, the optical film, the light guide plate 84 and the reflective sheet 85 are all provided with through holes to give way to the backplane module 90 and the functional element 200. Orthographic projection of the through hole of the optical film material, the through hole of the light guide plate 84, the through hole of the reflector plate 85 and the camera shooting hole A, orthographic projection of the through hole of the light guide plate 84, orthographic projection of the through hole of the optical film material and the through hole of the reflector plate 85 are all surrounded around the orthographic projection of the camera shooting hole A. The light guide plate 84, the reflector 85 and the back plate module 90 are sequentially stacked and fixedly connected, and the optical film, such as the first brightness enhancement film 81, may be stacked and connected with the second polarization film 50.
For the designations above and below, "first brightness enhancement film", "second brightness enhancement film" and "brightness enhancement film" may be interchanged, for example, "first brightness enhancement film" may also be referred to as "second brightness enhancement film" and may also be referred to as "brightness enhancement film".
In one embodiment, the first and second brightness enhancement films 81 and 82 may also be called BEF (brightness enhancement Film), which is an optical Film with a uniform prism pattern precisely formed on a surface of PET (Polyethylene Terephthalate) having excellent transparency by using acrylic resin. The front luminance can be improved by about 100% by assembling it in front of the backlight and focusing the light emitted by the light source towards the user of the display device (in the case of two orthogonal sheets, there is a mode vertical BEF). The light not used outside the viewing angle is recycled by the light re-reflection effect and collected at the most appropriate angle. In one embodiment, the first brightness enhancement film 81 and the second brightness enhancement film 82 may be an integral film.
In one embodiment, the diffusion sheet 83 may also be called a diffusion plate (Diffuser), and its main function is to provide a uniform surface light source for the display module 300. The base material of the diffusion sheet 83 is selected from materials having high light transmittance, such as PET (polyethylene terephthalate), PC (Polycarbonate), and PMMA (polymethyl methacrylate). The diffusion sheet 83 may be a diffusion film substrate, in which a particle of chemical particles is added as a scattering particle, and the fine particles of the diffusion sheet 83 are dispersed between the finger layers, so that the light passes through the diffusion sheet 83 and continuously passes through two media with different refractive indexes, and at the same time, the light undergoes many refraction, reflection and scattering phenomena, thus creating an optical diffusion effect.
In an embodiment, the first Brightness Enhancement Film 81, the second Brightness Enhancement Film 82, and the diffusion sheet 83 may be an integral structure, or may be replaced by other materials, for example, the optical Film may be DBEF (Dual Brightness Enhancement Film), and of course, the optical Film may also be other films capable of improving the light emitting efficiency of the optical Film assembly 80 or improving the light emitting effect of the optical Film assembly 80. In an embodiment, one or two of the first brightness enhancement film 81, the second brightness enhancement film 82, and the diffusion film 83 may be omitted.
In one embodiment, the light guide plate 84 may distribute the light emitted from the light source. Of course, the optical film assembly 80 may also include a light emitting component such as a light source to emit light.
In one embodiment, the reflective sheet 85 can make the light go only in the direction of the first glass substrate 30 and the second glass substrate 40.
Referring to fig. 4 and 6, fig. 6 is a schematic structural diagram of the backplane module 90 in fig. 4. The backplane module 90 may include a backplane 91 and a glue frame 92. Specifically, the back plate 91 is provided with a camera hole a. The rubber frame 92 is fixed around the camera hole a and extends into a through hole formed in the second polarizer 50 in the display module 300 to be hermetically connected with the second glass substrate 40, so as to prevent light from entering the camera hole a from an area between the second polarizer 50 and the rubber frame 92 and causing the problem of light leakage of the camera hole a. In an embodiment, the plastic frame 92 may be made of black plastic, and the light leaking from the sidewall of the through hole of the light guide plate 84 is absorbed by the light absorption effect of the black plastic frame 92, so as to solve the problem of bright lines and bright spots of the display image at the position of the blind hole caused by the light leakage re-entering the optical film. In an embodiment, the rubber frame 92 is used to prevent light from entering the camera hole a from the area between the second polarizer 50 and the rubber frame 92, which causes light leakage in the camera hole a, so that the rubber frame 92 is used to block light, and can be used as a light blocking member, which can be replaced by other light blocking members. In one embodiment, the rubber frame 92 absorbs the light leaking from the side wall of the light guide plate 84 at the through hole by using the light absorption effect, so as to solve the problem of bright lines and bright spots of the display image at the position of the blind hole caused by the light leakage entering the optical film again, so that the rubber frame 92 is used for light absorption, can be used as a light absorption strip, and can be replaced by other light absorption strips. Of course, the light absorbing strip and the light shielding member may be the same object, such as a black plastic frame.
Referring to fig. 4 and 6, the rear panel 91 may include a rear panel main body 911 and a bending portion 912 extending from an edge of the rear panel main body 911 at the image capturing hole a to one side of the second polarizer 50.

In an embodiment, the bending portion 912 can be omitted, and the plastic frame 92 can be directly fixed on the back plate main body 911. In one embodiment, the material of the back plate 91 may be iron metal.
