2near, surface reflectivity reaches minute surface and is less than 1%, unrestrained is instead less than 0.1%, and under the high light environment of high-altitude, demonstration information has good readability.External front glass of the same trade improves optics and customizes and realizes this object, but cost costliness, cycle are longer, can not meet the flourish of domestic airborne field of liquid crystal display.
Affect the many factors of high light readability, as the factor such as brightness, surface reflectivity of ambient light ambient light illumination, airborne cockpit design, observer's orientation, display.
Liquid crystal display surface reflectivity is mainly determined by the liquid crystal display assembly of front end, is the stack of each interface reflectivity.Liquid crystal display assembly comprises liquid crystal display, and front glass is located at liquid crystal display front end, is mapped to each interface in front glass and liquid crystal display and all can produces reflection.After liquid crystal display is determined, the reflectivity in screen is fixed, and the surface reflectivity of liquid crystal display assembly is higher conventionally, larger on showing the readability impact of information.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reflectivity that can reduce liquid crystal display assembly is provided, and the information under high light environment of realizing is readable, and the front glass of the low liquid crystal display of cost.
To achieve these goals, the technical solution adopted in the utility model is:
The front glass of this liquid crystal display, described liquid crystal display comprises liquid crystal display, described front glass is bonded in described liquid crystal display one side; Described front glass comprises anti-reflection glass and shield glass, also comprises the anisotropic membrane being located between described anti-reflection glass and described shield glass; Described shield glass one side and described anisotropic membrane are bonding, described shield glass opposite side and described liquid crystal display bonding.
Described shield glass is ITO electro-conductive glass.
One side of described shield glass and described liquid crystal display bonding is provided with index matching layer.
Described liquid crystal display comprises backlight assembly and liquid crystal display assembly, and liquid crystal display assembly is connected by circuit unit with backlight assembly.
Described liquid crystal display assembly comprises described liquid crystal display, is provided with well heater at described liquid crystal display opposite side, and described front glass and well heater are bonded on described liquid crystal display by optical cement respectively.
The utility model has the advantage of: the front glass of this liquid crystal display, in shield glass and anti-reflection glass, part increases anisotropic membrane; Anisotropic membrane, as asymmetric absorbing medium, carries out high-level efficiency decay to coming from extraneous natural light, carries out high-level efficiency and sees through coming from linearly polarized light in liquid crystal cell, reach reflectivity and significantly reduce, and display brightness changes small effect; Can reduce the reflectivity of liquid crystal display assembly, the information under high light environment of realizing is readable.
Use ITO electro-conductive glass as screen layer, increase index matching layer at ITO interface and optical cement bonding interface, reduce optical shield layer and bind the reflectivity bringing.Design by coupling, the reflectivity at this interface can be controlled in 0.3%～0.5% scope.
Adopt surface reflectivity between 0.2%～0.3% anti-reflection glass, the surface reflectivity of liquid crystal display assembly can reach to control to and be less than 1%.By liquid crystal display surface treatment, and in front glass manufacturing process, do not introduce the diffuse reflectance factor, can control to whole display diffuse reflectance and reach minimum (0.1%).
The front glass of this liquid crystal display, makes liquid crystal display surface reflecting effect can meet readable performance under high light environment, and with short production cycle, and cost of manufacture is low.
