According to the double-sided adhesive tape for the LCD module, disclosed by the utility model, the light shading and shielding performance is good, the light loss can be reduced, and a high scattering role on reflected light is achieved, so that the uniformity of the reflected light is guaranteed; and the electricity leakage or breakdown, electrical line short circuit and blasting of electronic products can be effectively prevented.
Description
Technical field
The utility model relates to a kind of shading rubber belt, relates in particular to a kind of liquid-crystal display module double sticky tape.
Background technology
Be the electronic information epoch now, the electronic products such as mobile phone, computer, digital camera are day by day universal, and fixing requirement of LCD liquid-crystal display and backlight module need to a kind of adhesive tape.For example, in liquid crystal indicator, speculum, reflector plate, diffusion disk need respectively to be fixed together by adhesive tape and light guide sheet.
In addition, display panels is fixed on diffusion disk or prismatic lens with adhesive tape, or with the spiral shell inspection, is fixed in cover on diffusion disk or prismatic lens.; in being provided with the liquid crystal indicator of backlight module, in order to effectively utilize the light from light source, when the light from backlight module incides outside the active area frame of display panels; preferably make this light again reflex to reflector plate one side, be utilized in the active area frame.
On the other hand, when observing display panels, near the active area frame, to increase sharp be bad in brightness.Therefore, how to design a kind of unwanted external light reflection that prevents, make brightness evenly and make the adhesive tape of picture distinctness become the direction that those of ordinary skills make great efforts.
Summary of the invention
The utility model provides a kind of liquid-crystal display module double sticky tape, and this double sticky tape has good shading shielding properties, can reduce light loss, and it has high scattering process to reflected light, thereby has guaranteed catoptrical even; And can effectively prevent the electric leakage of electronic product or puncture, wire short-circuiting and product explosion.
For achieving the above object, the technical solution adopted in the utility model is: a kind of liquid-crystal display module double sticky tape, comprise the transparent PET thin film layer, the upper surface of this transparent PET thin film layer and lower surface are coated with respectively black ink layer, the white ink layer, this another surface of white ink layer is one to have the uneven surface of concave point and salient point, the surface-coated of this uneven surface has the first adhesive-layer, another surface-coated of black ink layer has the second adhesive-layer, the first separated type material laminating is overlying on another surface of described the first adhesive-layer, the second separated type material laminating is overlying on another surface of described the second adhesive-layer.
In technique scheme, further improved technical scheme is as follows:
1. in such scheme, the roughness of described white ink layer uneven surface is 0.1um～5um.
2. in such scheme, the Thickness Ratio of described transparent PET thin film layer, black ink layer and white ink layer is 10:1～10:1～10.
3. in such scheme, described first, second separated type material layer is off-style paper layer or release film layer.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model liquid-crystal display module double sticky tape, it has good shading shielding properties, can reduce light loss; And another surface of white ink layer is one to have the uneven surface of concave point and salient point, and it has high scattering process to reflected light, thus guaranteed catoptrical evenly; Secondly, the utility model double sticky tape can cut randomly, and meets various electronic product shape needs, thus the fire retardant insulating of inner part prevent the electric leakage of electronic product or puncture, wire short-circuiting, burning and product explosion.
