Embodiment
The present invention will be further elaborated using specific embodiment below.Obviously, described embodiment is only
Some embodiments of the present application, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of the application protection.
Embodiment one
The embodiment of the present invention provides a kind of based on touch control display visual component in the sun.Referring to Fig. 3 and Fig. 4 institutes
Show, the component includes touch-screen 1 and/or protective glass, and LCDs 2.
The touch-screen 1 and/or the protective glass, transparent optical cement is additionally provided between the LCDs 2
Adhesive layer 3；
The refractive index of the optical cement adhesive layer 3 and the difference of glass refraction are within a preset range；
The touch-screen 1 and/or the protective glass are bonded in the LCDs by the optical cement adhesive layer 3
On the polaroid on 2 preceding surface.
The difference of the refractive index of optical cement adhesive layer and the refractive index of glass is in the range of 0-0.01.Preferably, from light
Glue is learned as the material of the optics adhesive layer, i.e. optical cement adhesive layer is that optical cement is the optical cement adhesive layer that material is made.
The refractive index of optical cement almost identical with glass is all 1.49.
Preferably as a kind of preferably embodiment, the surface of touch-screen 1 and/or protective glass is coated with AR (Anti-
Reflection) anti-reflection layer.
Preferably, touch-screen is polaroid resistor type touch panel.
The readable technical scheme of enhancing liquid crystal display used in the prior art in the sun, is that must increase liquid crystal
The external contrast of screen, increases the backlight illumination of display and reduces the brightness of reflected light to increase external contrast value.And increase
The brightness of big backlight can increase the power consumption of liquid crystal display, and heating can reduce the reliability of display, and the side that the present invention is used
Method is to reduce the brightness of reflected light.Specifically, the present invention using optics binding display screen by touch screen or protective glass with transparent
Optical cement be bonded on the polaroid on the preceding surface of liquid crystal display, be all 1.49 because the refractive index glass of optical cement is almost identical,
Therefore two reflectings surface are eliminated, while having plated AR anti-reflection layers on the surface of touch screen or protective glass so that entirely to outside
The reflectivity of light only has 0.4%, and lower reflection loss means readable under more preferable contrast, the lumen of backlight 500, daylight,
It is readable under 800 lumens, strong light.Optics binding not only substantially increases readability of the display screen under strong light, and also add
The reliability of display in harsh environments.
Embodiment two
