Embodiment
In order to make technical matters solved by the invention, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment
This example carries out specific explanations explanation by inventing the touching display screen provided, and as shown in Figure 2, comprises 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 comprises the visible area 1a that is positioned at core and visible area 1a with the non-visible area 1b of periphery along part, also namely the rectangular region of touch screen 1 core is visible area 1a, frame-shaped portion beyond the 1a of visible area 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;
The present invention is understood further for making those skilled in the art, the first orientation of composition graphs 3 to 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, draw the FPC (flexible print circuit board) of signal and be usually arranged on upper end, usually will " return ", " option ", " HOME key " etc. be made in lower end.
Wherein, the touch screen above described adhesive glue 4 is integrated with pressure sensitive circuit S2 along in non-visible area 1b in 1 week.
The principle of work of this pressure sensitive circuit S2 is: when touch screen 1 applies pressure, to cause its pressure sensitive circuit S2 that deformation occurs, so, to this pressure sensitive circuit S2 be caused relative to the capacitance variations between metal center 3, by analyzing the electric capacity before and after change, the position of pressurized can be oriented.
In this example, be not limited to the touch screen 1 of which kind of concrete structure, the position of its pressure sensitive circuit S2 is also without the need to being particularly limited to, as long as it leaves sufficient space for arranging this pressure sensitive circuit S2.As preferred mode, be preferably arranged on two long side direction.
Touch screen 1 generally comprises panel 13 and sensing layer, sensing layer is generally that single or multiple lift ITO (English full name: IndiumTinOxide, Chinese full name: tin indium oxide) film layer structure is compounded on glass or film (being generally PET (polyethylene terephthalate) material to prepare); Panel 13 and sensing layer are fitted by glue-line by centre, be 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 is a kind of transparent conductive film generated by special process on even carrier (or claiming matrix, substrate etc.).
Such as, generally common be double-deck ito film layer compound on glass panels, namely GFF (English full name: Glass-Film-Film, Chinese namely: glass-film-film) capacitance plate.Main for GFF capacitance plate in this example, introduce and how pressure sensitive circuit S2 is integrated in touch screen 1.
Certainly, the silver that touch screen 1 is also included in wherein silk-screen and Electrode connection starches line, pin P drawn by this silver slurry line, by this pin P and FPC17 (English full name: FlexiblePrintedCircuit, Chinese full name: flexible print circuit board) electrical connection, as shown in Fig. 3, Fig. 9, also comprise simultaneously and this touch screen 1 is carried out FPC17 binding, be namely electrically connected with the mainboard on portable type electronic product by this FPC.It is conventionally known to one of skill in the art, repeats no more.
