At this, still suppose in the position of capacitance touch screen liquid crystal board module capacitance touch screen cover-plate glass 1 outside surface, show that light intensity and environmental light intensity all are 100.
Because capacitance touch screen inductor 2 main line layers take lines as main, can be thought glass surface, glue together almost no-reflection of rear cemented surface with capacitance touch screen cover-plate glass 1.Post the antireflection pad pasting outside the electrically conducting transparent screen layer of the inductor glass of capacitance touch screen, this unitized construction reflectivity is 2.4% (1.7%+0.7%).
In addition, because the liquid crystal cell 3 of described liquid crystal panel unit is provided with antireflection rete 9 towards a side of touch-screen, like this, the reflectivity of liquid crystal board front surface has original 4% to be reduced to 0.7%.
Adopt of the present utility model without absorbent layer structure (situation of light-absorption layer 11 is not set between capacitance touch screen cover-plate glass 1 and the capacitance touch screen inductor 2), whole capacitance touch screen liquid crystal board module capacitance touch screen cover-plate glass 1 outside surface is reduced to 3.1% with inner each surperficial reflectivity, in addition, described capacitance touch screen cover-plate glass 1 front surface is provided with optics antireflecting film 10, reflectivity is reduced to 0.5% by original 4%, and whole like this module reflectivity just is 3.6%.Display light and environmental interference light ratio value are brought up to 28 by 6.25, bring up to original 4.4 times.
Adopt the absorbent layer structure (situation of light-absorption layer 11 is set between capacitance touch screen cover-plate glass 1 and the capacitance touch screen inductor 2) that has of the present utility model, because the existence of this polaroid being arranged, the ambient light intensity that passes this polaroid arrival module internal reduces half, and whole capacitance touch screen liquid crystal board module capacitance touch screen cover-plate glass 1 outside surface just is reduced to 1.55% with inner each surface to the environment reflection of light.In addition, described capacitance touch screen cover-plate glass 1 front surface is provided with optics antireflecting film 10, and reflectivity is reduced to 0.5% by original 4%.Like this, whole module displays regional reflex rate just is 2.05%, and display light and environmental interference light ratio value are brought up to 49 by 6.25, brings up to original 7.8 times.
Comprehensive above the discussion adopted the utility model structure, and whole capacitance touch screen liquid crystal board module displays regional reflex rate can be reduced to 3.6% or 2.05% by 16% of existing structure, and display effect can significantly be improved.
[0041] disclosed more than only is several specific embodiment of the present utility model, but the utility model is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
