Technical Field
The invention relates to a polaroid, in particular to a polaroid capable of realizing no frame on four sides of a display screen and application thereof.
Background
The liquid crystal display (TFT-LCD) generally includes the display area used for displaying the picture and locates at the peripheral lead wire area of display area, lead wire area is used for drawing out the grating, data link, public electrode wire, etc. of the liquid crystal faceplate, in order to connect it with corresponding drive circuit, the existing light-tight way all around is generally to use the cover plate to cover all shading ink or shading tape all around, and the setting of the cover plate can lead to the frame of the flat panel display to be wider, with the development of science and technology, most display screens can achieve the trilateral frameless, can't realize the frameless at the binding signal input side, can't meet many young consumers ' demand for wide field of vision, and increase and laminate the process and relevant apparatus to cause the craft tedious, the yield is low, the cost is high, easy to damage, but how to realize the frameless four sides has not seen the.
Disclosure of Invention
In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a polarizer capable of realizing no frame on four sides of a display screen and an application thereof, which can effectively solve the problems of high cost and easy damage of equipment of the frame on four sides of the display screen.
The invention solves the technical scheme that the polaroid capable of realizing no frame on four sides of a display screen comprises a protective layer, a release film layer and a TAC film layer, wherein a first TAC film layer is compounded below the protective layer, a light shielding layer is compounded below the first TAC film layer, a PVA film layer is compounded below the light shielding layer, a second TAC film layer is compounded below the PVA film layer, a pressure-sensitive adhesive is compounded below the second TAC film layer, and the release film layer is compounded below the pressure-sensitive adhesive to form the first polaroid; the light shielding layer comprises a display area in the middle and a light shielding area on the periphery of the display area, and a light shielding coating is coated on the light shielding area.
The application of the polaroid with the four edges free of the frame in the production of the display screen with the four edges free of the frame can be realized.
The invention has simple structure, reduces the manufacturing process difficulty of realizing no frame on the four sides of the display screen, reduces the manufacturing and material cost and reduces the working procedures, thereby improving the working efficiency and having good social and economic benefits.
