Need in the sun or outdoor carry out operation, and hand-held class small size electronic product such as mobile phone etc., also there are very high probability needs
Used under outdoor solar light.
And touch screen is directly added in liquid crystal screen surfaces by a part of electronic product at present, exist between touch screen and liquid crystal display
The air gap, thus forms 3 reflectings surface from outside to inside, respectively touch-control screen surfaces, between touch screen and air, air with
Between liquid crystal display.It is shown in Figure 1, if without specially treated, each reflecting surface to the reflectivity of exterior light substantially
4.2%, the exterior light of 3 reflective surfaces is just 12.6%, about 1260 lumens.It is shown in Figure 2, if the surface brightness of screen is
1000 lumens, from interior toward nonlocal two reflectings surface, respectively liquid crystal display to air, air to the touch screen back side, by 2 reflections
Brightness after the reflection in face thoroughly to touch screen surface is 916 lumens.This make these electronic products out of doors under sunlight in use, with
The picture that family is seen has the brightness used up to be less than reflectance lightness, and reflected light makes white brighter, flooded black and other colors,
Make liquid crystal display readable very poor under strong light.
In view of the above-mentioned problems, a kind of Improving Measurements used at present, to reach the readability of enhancing liquid crystal display in the sun
Purpose, using increase liquid crystal display external contrast and increase the backlight illumination of display and increase external contrast value,
And the brightness for increasing backlight can increase the power consumption of liquid crystal display.
Utility model content
Led to solve technical scheme visual under sunlight of the prior art due to increasing the backlight illumination of display
Cause the technical problem of increase liquid crystal display power consumption, the utility model provides a kind of based on touch control display visual group in the sun
Part and method.
It is provided by the utility model a kind of based on touch control display visual component in the sun, including touch-screen and/or
Protective glass, and LCDs, also set between the touch-screen and/or the protective glass, with the LCDs
There is transparent optical cement adhesive layer；
The refractive index of the optical cement adhesive layer and the difference of glass refraction are within a preset range；
The touch-screen and/or the protective glass are bonded in the LCDs by the optical cement adhesive layer
On the polaroid on preceding surface.
Wherein, the difference of the refractive index of the optical cement adhesive layer and the refractive index of glass is in the range of 0-0.01.
Wherein, the optical cement adhesive layer is that optical cement is optical cement adhesive layer made of material.
Wherein, the surface of the touch-screen and/or the protective glass is coated with AR anti-reflection layers.
Wherein, the touch-screen is polaroid resistor type touch panel.
It is provided by the utility model a kind of based on touch control display visual component in the sun, in touch-screen and liquid crystal
Optical cement adhesive layer is set between display screen, and selective refraction rate meets the optical cement adhesive layer of preparatory condition, when optics is gluing
Close layer it is almost identical with glass refraction all be 1.49 when, two reflectings surface can be eliminated, so as to reduce the brightness of reflected light；Due to
Backlight need not be strengthened, thus avoided due to extra power consumption caused by enhancing backlight；
Meanwhile plate AR anti-reflection layers on the surface of touch-screen or protective glass so that whole reflection of the component to exterior light
Rate only has 0.4%, substantially increases readability of the display screen under strong light.

Embodiment
The utility model will be further elaborated using specific embodiment below.Obviously, described embodiment is only
Only it is some embodiments of the present application, rather than whole embodiments.It is common based on the embodiment in the utility model, this area
The every other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model of the application protection
Enclose.
The utility model embodiment provides a kind of based on touch control display visual component in the sun.Referring to Fig. 3 and Fig. 4
Shown, the component includes touch-screen 1 and/or protective glass, and LCDs 2.
Transparent optical cement is additionally provided between the touch-screen 1 and/or the protective glass, with 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
Material of the glue as the optics adhesive layer is learned, i.e. optical cement adhesive layer is that optical cement is optical cement adhesive layer made of material.
The refractive index of optical cement almost identical with glass is all 1.49.
Preferably as a kind of preferable 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, increase the backlight illumination of display and the brightness of reduction 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 utility model uses
Method be reduce reflected light brightness.Specifically, the utility model by touch screen or protects glass using optics binding display screen
Glass is bonded in transparent optical cement on the polaroid on the preceding surface of liquid crystal display, because the refractive index glass of optical cement is almost identical,
It is all 1.49, therefore eliminates two reflectings surface, while AR anti-reflection layers have been plated on the surface of touch screen or protective glass so that is whole
The individual reflectivity to exterior light only has 0.4%, and lower reflection loss means more preferable contrast, the lumen of backlight 500, daylight
Under readable, 800 lumens, it is readable under strong light.Optics binding not only substantially increases readability of the display screen under strong light, but also

The utility model set polaroid can bind the mode of liquid crystal display die set with AR coating techniques with optics, effectively
Solves touch display visual scheme in the sun, improving can be readability up to 400% under daylight, improves impact resistance and is up to
300%, no moisture, which enters, forms water smoke, prevents from condensing and is atomized, and lighter and thinner display can be used to design, it is strong to be bonded chemistry
Change protection film glass and add the shock resistance of screen, reduce the probability of destruction, even if rupture, due to optics bonding will not also fall down it is broken
Piece is hurted sb.'s feelings.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change, there is no necessity and possibility to exhaust all the enbodiments.As long as those of ordinary skill in the art are not making
The every other embodiment obtained under the premise of creative work, belong to the scope of the application protection.
