Need to prove, when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may have simultaneously centering elements.
Unless otherwise defined, all technology of using of this paper and scientific terminology are with to belong to the implication that those skilled in the art of the present utility model understand usually identical.The term that uses in instructions of the present utility model herein is not intended to be restriction the utility model just in order to describe the purpose of specific embodiment.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
The utility model proposes a kind of optical filter box and use the touch display screen of this optical filter box.This optical filter box can be realized touch operation and optical filter function, thereby makes touch display screen have the touch Presentation Function.
See also Fig. 1, the touch display screen 100 of an embodiment comprises the lower polaroid 10, TFT electrode 20, Liquid Crystal Module 40, public electrode 50, diaphragm 60, optical filter box 200 and the upper polaroid 70 that stack gradually.
Structure and the function of the lower polaroid 10 of the present embodiment, TFT electrode 20, Liquid Crystal Module 40, public electrode 50, diaphragm 60 and upper polaroid 70 can be identical with existing product, do not repeat them here.
Be appreciated that for using backlight as polarized light source, as the OLED polarized light source, need not lower polaroid 10, only need the upper polaroid 70 to get final product.Diaphragm 60 also can omit.
But touch display screen 100 has tangible operation and polarized light function simultaneously, makes display screen have the touch Presentation Function.Display screen can be the LCDs of straight-down negative or side down light source.
Following emphasis is described optical filter box 200.
