Referring to fig. 2 and 3, in an embodiment of the present application, a display screen is disclosed, wherein the display screen includes a light-emitting backplane 10, an optical component 20 and a shielding component 40, and a groove 11 is formed on a light-emitting side of the light-emitting backplane 10; the optical assembly 20 is connected with the light-emitting back plate 10 and is positioned in the groove 11, and an assembly gap 30 is formed between the optical assembly 20 and the side wall of the groove 11; the shutter member 40 is disposed on the optical member 20 to cover the fitting gap 30.
The display screen disclosed by the invention can be used on a television as a part of a full screen television module, and also can be used on a mobile phone, an intelligent watch or a computer as a component of the display screen. Therefore, it should be noted that, in the embodiment of the present invention, the display screen of the full-screen television is taken as an example to describe the specific structure and the operating principle of the present invention, but the application of the present invention is not limited to the display screen of the television, and the present invention can also be applied to the production and use processes of other similar workpieces.
During production, the light-emitting back plate 10 and the optical assembly 20 are assembled firstly, and the light-emitting back plate 10 can be a single part formed by integrally forming a traditional back plate and a middle frame or a part formed by assembling the back plate and the middle frame; according to different use environments of the display screen, different light-emitting back plates 10 can be correspondingly selected during manufacturing, the processing technology can be flexibly adjusted, the processing technology is simplified, and the cost is reduced.
In order to avoid collision between the optical assembly 20 and the light-emitting back plate 10 in the assembly process, in order to reduce damage, the size of the optical assembly 20 can not be completely attached to the size of the groove 11 in the actual manufacturing process, so an assembly gap 30 is formed between the side walls of the optical assembly 20 and the groove 11, the embodiment covers the assembly gap 30 through the shielding assembly 40 which is arranged simultaneously, a light emergent surface of the display screen is complete, seamless attachment is realized, the attractive appearance of the display screen is improved, the inner cavity of the display screen can be sealed, water accumulation in the inner cavity of the display screen is prevented, dust accumulation and other problems are avoided, the effective service life of the display screen is prolonged, and the use experience of products is improved.
In the use process of the display screen, the light-emitting back plate 10 of the display screen emits light, and the light rays penetrate through the optical assembly 20 to be emitted; on the light-emitting surface of the display screen, light is emitted from the surface of the optical component 20, the brightness is high, and the light path of the light transmitted into the assembly gap 30 is changed due to reflection, refraction and other reasons, and is different from the light path of the light emitted from the surface of the optical component 20, and the brightness is also different, so that dark stripes are easy to appear on the display screen, and the appearance is influenced; the assembly gap 30 is shielded by the shielding component 40, so that the emission of light rays in the assembly gap 30 is reduced, and the problem of poor light emitting effect of the display screen can be solved.
As shown in fig. 2, as an implementation manner of this embodiment, it is disclosed that the optical assembly 20 includes an optical film layer 21 and an upper polarizer layer 22 sequentially stacked along an outgoing light path of the light-emitting backplane 10, where the optical film layer 21 is fixed at the bottom of the groove 11, and different optical films may be selected to form the optical film layer 21 according to a use requirement of the display device, for example, as shown in fig. 2, in a television module, the optical film layer 21 may be set to include a lower polarizer layer 211, a lower glass substrate layer 212, an upper glass substrate layer 213, and other optical structures; of course, other electronic devices may also include optical structures such as diffuser layers, enhancement film layers, lens film layers, and the like. By flexibly adjusting the structure of the optical film layer 21, the final imaging effect of the display screen can be better, the display screen is suitable for more use environments, and the use value of the display screen is improved.
As shown in fig. 2, the optical film layer 21 in this embodiment is fixed on the light-emitting back plate 10, and is generally fixedly connected by using an adhesive block such as a foam adhesive, a double-sided adhesive, etc., the optical film layer 21 includes a lower polarizer layer 211, a lower glass substrate layer 212, and an upper glass substrate layer 213, and is adhered around the lower surface of the lower glass substrate by disposing the foam adhesive 13 at the bottom of the groove 11, the lower polarizer layer 211 is disposed at the middle position of the lower glass substrate, and avoids the foam adhesive 13, the upper glass substrate layer 213 has the same shape and size as the lower glass substrate layer 212, and is completely overlapped on the lower glass substrate, and then the upper polarizer layer 22 is disposed on the upper glass substrate layer 213, so as to form the complete optical assembly 20.
As shown in fig. 4, in the present embodiment, the shielding assembly 40 is disposed around the edge of the upper polarizer layer 22, and a side of the shielding assembly 40 away from the upper polarizer is in contact with the light-emitting rear panel 10. The shielding component 40 is arranged at the edge of the upper polarizer layer 22, so that the light rays emitted from the light-emitting surface are not blocked, and the overall display effect on the upper polarizer layer 22 is prevented from being influenced; and set up the edge at last polarizer layer 22, extend on the plane that last polarizer layer 22 was located equivalently, can not bulge in the play plain noodles, also can not increase the thickness of display screen, be favorable to display device's frivolousization.
In addition, in order to make the shielding assembly 40 disposed at the edge of the upper polarizer layer 22 better cover the assembly gap 30, in another implementation manner of the embodiment, it is disclosed that a side of the optical film layer 21 facing away from the light-emitting back plate 10 is flush with the opening of the groove 11. Go up polarizer layer 22 and pile up the setting on optics rete 21, so go up the plane that polarizer layer 22 was located and highly higher than the opening part of recess 11, so set up at the shading subassembly 40 of last polarizer layer 22 border position outside extending to recess 11, and be close to the one end of luminous backplate 10, contact through lower surface and luminous backplate 10, thereby can cover the fitting gap 30 in the recess 11 completely, realize real seamless cooperation, make the inside formation confined space of display screen, isolated outside air, impurity, bad environmental factor such as steam.
Certainly, the shielding assembly 40 can be manufactured separately and then fixed on the upper polarizer layer 22, but a connecting trace is inevitably generated between the shielding assembly and the upper polarizer layer, so that the light-emitting surface of the display screen is not beautiful enough; therefore, in another implementation manner of the present embodiment, it is disclosed that the shielding member 40 and the upper polarizer layer 22 are integrally formed films. For example, the shielding assembly 40 and the upper polarizer screen may be a complete polarizer without a connecting gap; the shutter assembly 40 thus formed has multiple benefits: firstly, the shielding assembly 40 and the upper polarizer layer 22 are integrated, so that the shielding assembly 40 and the upper polarizer layer are not easy to separate, and the structural strength of the whole polarizer ensures that the shielding assembly 40 is stable and is not easy to bend or fold in the use process of the display screen, so that the smoothness of a light-emitting surface is maintained; secondly, during manufacturing, the shielding assembly 40 and the upper polarizer layer 22 can be mounted on the light-emitting back plate 10 and the optical film layer 21 in one step, so that the assembly steps are simplified; thirdly, the shielding component 40 does not need to be purchased separately, so that the production cost is saved; fourth, the polaroid belongs to the optical sheet, and the subassembly 40 surface area that shelters from that sets up alone is littleer, and is easy broken, and the subassembly 40 that shelters from as an organic whole even with last polaroid layer 22, holistic mechanical properties is better, can reduce the damaged risk in the installation.
As shown in fig. 2 and fig. 3, as another implementation manner of this embodiment, it is disclosed that a surface of the light-emitting back plate 10, which is in contact with the shielding assembly 40, is a first contact surface 12, and an adhesive layer 50 is disposed on the first contact surface 12. Although the upper polarizer layer 22 is fixed to the optical film layer 21 by adhesion in the conventional manufacturing process, the light-emitting back sheet 10 and the shielding member 40 still have poor sealability if they are merely in contact with each other; so set up the adhesive linkage on first contact surface 12 and can make and shelter from realizing the stable connection between subassembly 40 and the luminous backplate 10, moreover, through set up the round adhesive linkage on luminous backplate 10 (the drawing is the sectional view, the opening of actual luminous backplate 10 upper groove 11 is circular or rectangle, be equipped with annular adhesive linkage around the opening of recess 11), it is better to make the connection gas tightness of sheltering from subassembly 40 and luminous backplate 10, the inside totally enclosed inner chamber that then forms of display screen, thereby it opens with the environment is isolated, avoid the deposition, ponding scheduling problem.
In addition, in actual production, the foam adhesive arranged in the groove 11 during assembly has certain ductility, and the height of the upper polarizer layer 22 can not be accurately estimated by pressing and attaching the upper polarizer layer to the optical assembly 20, so that it is difficult to attach the shielding assembly 40 to the first contact surface 12 precisely and tightly in advance through precise calculation, and the gap between the first contact surface 12 and the shielding assembly 40 can be filled by the adhesive layer 50.
It should be noted that the adhesive layer 50 in the present embodiment includes, but is not limited to, glass glue, double-sided glue, epoxy glue, waterproof glue, and the like.
Referring to fig. 5 and 6, as another embodiment of the present application, a method for manufacturing a display screen is disclosed, wherein the method includes the following steps:
s100, as shown in fig. 5 (a), providing a light-emitting backplane 10, and forming a groove 11 on a light-emitting side of the light-emitting backplane 10;
s200, providing an optical assembly 20, and extending a polarizing film out of the edge position of the optical assembly 20;
s300, as shown in fig. 5 (b), adhering foam to the bottom of the groove 11, and coating an adhesive layer 50 around the opening of the groove 11;
s400, as shown in fig. 5 (c), placing an optical assembly 20 into the groove 11, fixing the optical assembly 20 on the light-emitting back plate 10 through the foam adhesive, and simultaneously contacting the polarizing film with the adhesive layer 50 to adhere to the light-emitting back plate 10;

Because the relative position between the optical assembly 20 and the light-emitting back plate 10 is determined by the movement in the assembling process in the production process, and there may be a problem of displacement deviation, it cannot be guaranteed that the assembling gaps 30 on each display screen are the same in size, the optical assembly 20 is installed first, then the shielding assembly 40 is separately arranged to cover the assembling gaps 30, the size of the assembling gaps 30 can be flexibly matched to set the transparent film, so as to obtain a better shielding effect. The production flow of the sequential assembly has low process requirement and is easy to operate.
In another implementation manner of this embodiment, a manufacturing method of the display screen may be simulated when the display screen is manufactured by using a transparent film as the shielding component 40, in which a large-sized transparent film is used to completely cover the light-emitting back plate 10 and the optical component 20, and then the transparent film is cut, so as to quickly and accurately obtain the shielding component 40 with a proper size and a proper position, thereby improving the yield of the display screen while ensuring the production efficiency of the display screen.
Specifically, as another implementation manner of the present embodiment, it is disclosed that the transparent film is bonded to the light-emitting back plate 10. Firstly, the bonding connection mode is stable; secondly, an adhesive layer, such as a double-sided adhesive tape, a solid adhesive tape and the like, is arranged around the groove 11 to form an adhesive ring to be adhered to the outer edge of the transparent membrane, and the middle position of the transparent membrane can be free from being in contact with or connected with the optical assembly 20, so that a good fixing effect is realized, the production steps are simplified, and the production requirement is lowered; and thirdly, the light-emitting assembly can be completely sealed in the inner cavity of the display screen through bonding, so that the light-emitting assembly is protected, and impurities and water vapor in the air are isolated.
Specifically, as another implementation manner of the embodiment, it is disclosed that the shielding component 40 includes at least one of a rubber block, a foam block, a plastic block, and a glass block.
