Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, an embodiment of the present invention discloses a display panel 100, and the disclosed display panel 100 may include a cover plate 110, an adhesive layer 120, a polarizer 130, a first transparent layer 140, a second transparent layer 160, and a cushion layer 170, which are sequentially disposed; that is, the cover plate 110 is disposed on the upper surface of the polarizer 130 through the adhesive layer 120, the first transparent layer 140 is disposed on the lower surface of the polarizer 130, the second transparent layer 160 is disposed on the lower surface of the first transparent layer 140, and the cushion layer 170 is disposed on the lower surface of the second transparent layer 160.
An accommodating cavity 150 is formed between the first transparent layer 140 and the second transparent layer 160, so that the luminescent layer can be disposed in the accommodating cavity 150 and can be supported by the second transparent layer 160; the cushion layer 170 may be a structural member made of a flexible material such as foam or rubber, so that each layer of the cushion layer 170 can be protected by the cushioning effect thereof.
The cushion layer 170 is provided with a through hole 171 matched with the light inlet end of the camera 200, the region of the polarizer 130 opposite to the through hole 171 is a transparent region 131, the cover plate 110 is a structural member made of a transparent material, and the adhesive layer 120 is a transparent adhesive layer, so that light can sequentially pass through the cover plate 110, the adhesive layer 120, the transparent region 131 of the polarizer 130, the first transparent layer 140 and the second transparent layer 160 to irradiate to the through hole 171 of the cushion layer 170, and further the light inlet end of the camera 200 located in the through hole 171 can receive the light and form an image, thereby realizing the shooting function of the camera under the screen.
Meanwhile, the transparent region 131 of the polarizer 130 keeps the surface of the polarizer 130 flat, thereby facilitating the flat attachment between the polarizer 130 and the first transparent layer 140; therefore, compared with the conventional display screen with the through holes and the dispensing structure on the polarizer 130, the defect of unevenness on the surface of the polarizer 130 caused by glue protrusions formed after the OCR glue is solidified can be effectively avoided, and the problem that the display effect is affected by the newton ring phenomenon of the display image of the display screen 100 due to the deformation of the first transparent layer 140 caused by the extrusion of the glue protrusions on the first transparent layer 140 is prevented.
It is easy to understand that the remaining area of the polarizer 130 outside the transparent area 131 is required to be the polarization area 132 to ensure that the display panel 100 can normally display images; the transparent region 131 of the polarizer 130 may be a polarizer 130 structure formed by processing a corresponding region of the composite film in the composite manufacturing process of the polarizer 130; of course, the transparent region 131 of the polarizer 130 may also be formed by other processing methods, and the embodiment of the invention does not limit the manufacturing processing method of the polarizer 130.
In order to avoid the shortening of the service life of the display screen 100 caused by the oxidation of the light emitting layer disposed in the accommodating cavity 150, the accommodating cavity 150 may be filled with an inert gas, so that the inert gas isolates the light emitting layer from air and protects the light emitting layer, thereby facilitating the delay of the service life of the display screen 100; the inert gas is a gas which has stable chemical properties and is not easy to generate chemical reaction, such as nitrogen, helium, neon, argon and the like.
Of course, the accommodating cavity 150 may be vacuumized to form a vacuum cavity in the accommodating cavity 150, so as to prevent the light emitting layer inside the accommodating cavity 150 from contacting with air, and prevent the air from oxidizing the light emitting layer. Generally, the light emitting layer includes an organic light emitting material, a cathode and an anode, and as it belongs to the prior art, the structure of the light emitting layer is not described in detail in the embodiments of the present invention.

In order to hide the camera 200 under the display screen 100 better, the first transparent layer 140 may be a half mirror or other half mirror structure, and the half mirror reflective surface of the first transparent layer 140 faces the polarizer 130, so that the light emitted from the light emitting layer can smoothly pass through the first transparent layer 140 to enable the display screen 100 to normally display an image, and a user cannot easily see the camera 200 under the display screen 100 through the first transparent layer 140.
Of course, when shooting through the camera 200, in order to avoid the influence of the reflection action of the one-way perspective structure on the external light passing through the display screen 100 and then the camera 200, the one-way perspective structure with relatively low reflection may be adopted, so that the light transmittance of the one-way perspective structure is adapted to the requirement of the camera 200.
Meanwhile, the adhesive layer 120 may be an oca (optically Clear adhesive) adhesive layer; the OCA glue is a special adhesive for cementing transparent optical elements such as lenses and the like, can be cured at room temperature, and has the advantages of colorless transparency, light transmittance of over 90 percent, good cementing strength, small curing shrinkage and the like.
Based on the display screen 100 disclosed in the embodiment of the invention, the embodiment of the invention also discloses an electronic device, and the disclosed electronic device can comprise a shell, a camera 200 and the display screen 100 disclosed in the embodiment of the invention; display screen 100 sets up on the casing, and camera 200 sets up within the casing, and the light inlet end of camera 200 sets up with transparent area 131 relatively, so, just can make the light inlet end of camera 200 receive light and form an image, realizes the shooting function of camera under the screen. Typically, the camera head 200 is positioned within the through hole 171 of the cushion layer 170.
The electronic device can be an electronic device such as a smart phone, a tablet computer, an electronic book reader and the like.
In the above electronic device, the camera 200 is in the form of an off-screen camera.
Wherein, the number of the cameras 200 is at least one; the number of the transparent regions 131 is the same as that of the cameras 200, and the light inlet end of one camera 200 is arranged opposite to one transparent region 131. Meanwhile, the number of the through holes 171 is the same as that of the cameras 200, and one camera 200 is disposed inside a corresponding one of the through holes 171.
