Description
Technical field
The utility model relates to a kind of liquid crystal display, in particular a kind of device that improves liquid crystal display device light leakage.
Background technology
For meeting the visual demand of high light under duty, need to carry out functional glass reinforcing to liquid crystal display assembly, conventionally there is the functional glass of anti-reflection and shielding action in the laminating of liquid crystal display upper surface, why adopt glass baseplate to reinforce, be in order to meet the requirement of high level vibration environment, ensure the reliability of vibration.For meeting liquid crystal display random vibration environment stress screening conditional request, for 10 inches and following size, the functional glass of liquid crystal display upper surface laminating is generally selected 2.3mm thickness specification, can guarantee the reliability of vibration.
Based on the design of above-mentioned liquid crystal display, conventionally there will be surrounding light leak problem.Owing to having increased thicker functional glass at liquid crystal display upper surface, the liquid crystal display surrounding frame adhesive position light leak that conventionally can pass through backlight, causes certain angle can see that light leaks from liquid crystal display top surface edge.Affect acquisition of information, especially, under night flight pattern, the brightness of light leak place is too high, cannot clearly observe the demonstration information of the term of validity.Joint function glass not of common product, or the functional glass of laminating is very thin, the light leak at this place can block solution by the panel liquid crystal display top surface edge of directly fitting.So common product does not exist light leak problem substantially, above-mentioned liquid crystal display is generally deposited light leakage phenomena in various degree under certain angle.This light leak method of conventional process, conventionally use black silicon rubber-coated shading treatment, but effect is bad, inconvenient operation, its shortcoming main manifestations is: the one, and limited space, thinner black silicon rubber shaded effect is bad, still has more light transmission black silicon rubber; The 2nd, black silicon rubber-coated position, the more difficult control of size and dimension, not easy to operate; The 3rd, the black silicon rubber chemistry character applying is unstable, easily reacts with the optical cement of joint function glass, cause optical cement not solidify, or Long contact time causes optical cement variable color.
The generation of liquid crystal display surrounding frame adhesive position light leak, can be from liquid crystal display tectonic analysis, the surrounding of liquid crystal display effective display area is the BM layer of black, it can stop light to see through completely, BM layer surrounding is transparent frame adhesive, without interception, the light leak of above-mentioned conventional liquid crystal mainly sees through from BM layer surrounding frame adhesive position.The light leakage phenomena at this place has a strong impact on and under night flight pattern, shows obtaining of information.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device that improves liquid crystal display device light leakage is provided, and can not clearly obtain problem to solve liquid crystal display demonstration information.
The utility model is achieved through the following technical solutions: the utility model comprises liquid crystal display, shading rubber belt and functional glass, described liquid crystal display comprises the lower polaroid, lower baseplate glass, upper substrate glass and the upper polaroid that set gradually, functional glass is arranged on polaroid, shading rubber belt pastes successively at the edge of lower baseplate glass, upper substrate glass and upper polaroid, is covered with the upper substrate glass of shading rubber belt and the edge of upper polaroid and the edge of lower baseplate glass concordant.
The outward flange overlap joint of the BM layer of described shading rubber belt and liquid crystal display.Realize the seamless light leak that prevents.
The inner side at described shading rubber belt edge applies optical cement, carries out optical cement laminating and solidify after infrabar de-bubble.
Described shading rubber belt is the two-sided black belt of one-side band gum, and thickness is less than optical cement thickness.
If use shading rubber belt outwards to extend to liquid crystal display edge along BM layer, BM layer surrounding will there will not be light leakage phenomena so.Because the functional glass of liquid crystal display upper surface uses optical cement laminating conventionally, optical cement is easy to produce bubble in shading rubber belt inside edge, even enters effective display area, affects display effect.For head it off, need to first use optical cement in the bottoming of shading rubber belt inside edge, then infrabar de-bubble, removes optical cement and contacts the bubble producing with shading rubber belt, finally uses optical cement joint function glass.Can effectively avoid like this bubble to produce in shading rubber belt inside edge.Essential implementation mainly contains 3 points, and the one, select the two-sided shading rubber belt that is black of one-side band gum, outwards paste to liquid crystal display edge along BM layer; The 2nd, use optical cement to be coated in the bottoming of shading rubber belt inside edge; The 3rd, liquid crystal display is put to de-bubble in infrabar equipment, remove optical cement and contact with shading rubber belt the bubble of generation.
The utility model has the following advantages compared to existing technology: the utility model can solve the problem of liquid crystal display device light leakage, has eliminated the interference of light leak, and demonstration information can clearly be obtained, easy to operate, simple in structure, is widely used.
