In order to make this utility model be solved the technical problem that, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
Embodiment
The touching display screen that utility model is provided is carried out specific explanations explanation by this example, as in figure 2 it is shown, include metal center 3, touch screen 1 and display screen 2；Described display screen 2 is gluing below described touch screen 1；Within 3 weeks, along forming stage portion, described stage portion is provided with adhesive glue 4 to described metal center；
As shown in Figure 3, described touch screen 1 includes the visible area 1a and visible area 1a that the are centrally located part non-visible area 1b with edge, periphery part, namely the rectangular region of touch screen 1 core is visible area 1a, frame-shaped portion beyond visible area 1a is non-visible area 1b, and the non-visible area 1b lower surface of described touch screen 1 is pasted onto in described stage portion；
For making it is further understood that this utility model, first in conjunction with Fig. 3, the orientation of its touch screen 1 is briefly described, its touch screen 1 is generally rectangle, the right and left is long limit, upper and lower two ends are minor face, the FPC (flexible print circuit board) drawing signal is generally arranged at upper end, generally " return ", " option ", " HOME key " etc. is made in lower end.
Wherein, the touch screen above described adhesive glue 4 is integrated with pressure sensitive circuit S2 for 1 week along non-visible area 1b.
The operation principle of this pressure sensitive circuit S2 is: when applying pressure on touch screen 1, its pressure sensitive circuit S2 will be caused to deform upon, so, this pressure sensitive circuit S2 will be caused relative to the capacitance variations between metal center 3, by analyzing the capacitance before and after change, the position of pressurized can be oriented.
In this example, it is not limited to the touch screen 1 of which kind of concrete structure, the position of its pressure sensitive circuit S2 is without being particularly limited to, as long as it leaves the space of abundance for arranging this pressure sensitive circuit S2.As preferred mode, it is preferable that be arranged on two long side direction.
Touch screen 1 generally comprises panel 13 and sensing layer, sensing layer is usually single or multiple lift ITO (English full name: IndiumTinOxide, Chinese full name: tin indium oxide) film layer structure and is compounded on glass or thin film (being generally PET (polyethylene terephthalate) material to prepare)；Panel 13 and sensing layer are fitted by the middle glue-line that passes through, it is generally OCA (English full name: OpticalClearAdhesive, Chinese full name: Optical transparent adhesive) or UV glue (ultraviolet cured adhesive) fit, common at present laminating layer adopts OCA Double-face adhesive rubber alloy layer.ITO is a kind of N-type oxide semiconductor.It it is a kind of transparent conductive film generated by special process on even carrier (or claiming matrix, substrate etc.).
