Description

Polaroid capable of realizing no-frame four sides of display screen

Technical Field

The utility model relates to a polaroid, especially a can realize polaroid that display screen four sides do not have frame.

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.

SUMMERY OF THE UTILITY MODEL

To the above situation, for overcoming the defect of prior art, the utility model aims at providing a can realize the polaroid of display screen four sides no frame, can effectively solve display screen four sides frame, with high costs and the fragile problem of equipment.

In order to achieve the purpose, the utility model provides a technical scheme is, a can realize display screen four sides polaroid of no frame, including protective layer, release film layer and TAC rete, protective layer below compound have first TAC rete, first TAC rete below compound have the light shield layer, the light shield layer below compound has the PVA rete, PVA rete below compound has the second TAC rete, second TAC rete below compound has the pressure sensitive adhesive, the pressure sensitive adhesive below compound has the release film layer;

the light shielding layer comprises a middle display area and a light shielding area on the periphery of the display area, and the light shielding area is coated with a light shielding coating.

The utility model discloses simple structure reduces the processing procedure technology degree of difficulty that realizes the display screen four sides frameless, reduces manufacturing and material cost, reduces the process to improve work efficiency, had good society and economic benefits.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

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 2 is compounded below the protective layer 1, a light shielding layer 3 is compounded below the first TAC film layer 2, a PVA film layer 4 is compounded below the light shielding layer 3, a second TAC film layer 5 is compounded below the PVA film layer 4, a pressure-sensitive adhesive 6 is compounded below the second TAC film layer 5, and a release film layer 7 is compounded below the pressure-sensitive adhesive 6;

the shading layer 3 comprises a display area 3-1 in the middle and a shading area 3-2 at the periphery of the display area, and a shading coating is coated on the shading area 3-2.

In order to ensure better implementation effect, the shading coating is a frame shading shape formed by coating shading ink or shading glue, but is not limited to the two.

The thickness of the shading coating is less than 7 mu m.

The size of the display area 3-1 is the same as that of the display screen.

When the utility model is used in concrete, the common polaroid (prior art) is attached to the CF side of the Cell (prior art), then the terminals of the PCB (printed circuit board, prior art), COF (chip on film, prior art) and the TFT side of the Cell are connected together, then the polaroid of the utility model is attached to the TFT side of the Cell (namely the other side opposite to the CF side), the redundant polaroid on the TFT side is cut off, the glue is measured on three sides or four sides, finally the polaroid of the utility model is outward, namely the common polaroid is contacted with the backlight module and assembled on the backlight module (prior art), the display area of the polaroid of the utility model corresponds to the display area of the Cell, the shading area corresponds to the whole non-display area on the TFT side, the width of the TFT substrate of the terminal area of the Cell is increased for shielding and protecting the COF, in the display or television assembly process, the TFT side of the Cell panel is outward as the visible surface, thereby realizing the effect that four sides have no frame.

The utility model discloses simple structure reduces the processing procedure technology degree of difficulty that realizes the display screen four sides frameless, reduces manufacturing and material cost, promotes consumer expectation value and satisfaction, reduces the process to improve work efficiency, had good society and economic benefits.
