Embodiment
Below in conjunction with accompanying drawing most preferred embodiment of the present invention is described in further detail.
The electric resistance touch screen of band screen layer of the present invention as depicted in figs. 1 and 2, it comprises: the transparent base layer 1 that is made of glass or duroplasts flat board, be plated on the transparent conductive film layer 3 of transparent base layer 1 upper surface, superjacent outside surface is through cure process, smooth anti-friction plastic, transparent top layer 2, the inside surface of this transparent surface layer 2 is coated with transparent conductive film layer 4, there are many tiny transparent isolating points 7 that their insulation are separated between transparent conductive film layer 3 and the transparent conductive film layer 4, and there is insulating gel 6 that transparent isolating points 7 and two-layer nesa coating are isolated from the outside, it also comprises: the transparent conductive film layer 5 that is plated on transparent base layer 1 lower surface, this transparent conductive film layer 5 can be directly connected to the ground 10 of the application system of touch-screen cooperating, also can be connected to the ground 10 of the application system of touch-screen cooperating by the connecting line 8 that is electrically connected with it.
Described transparent conductive film layer 5 can be an indium tin oxide coating, also can be other conducting metal oxide coating.
Described connecting line 8 adopts but is not limited to plain conductor, FPC and hot pressing conductive paper.
Described transparent conductive film layer 5 adopts with being connected of connecting line 8 but is not limited to welding, hot pressing and stickup.
The ground 10 of described connecting line 8 and LCD MODULE 9 also is to connect between the ground 10 of application system of touch-screen cooperating to adopt but be not limited to welding, hot pressing and stickup.
A kind of method on ground 10 that transparent conductive film layer 5 is connected to the application system of touch-screen cooperating is: connecting line 8 one ends that FPC is constituted with anisotropy conductiving glue hot pressing on the nesa coating 5 of touch-screen, the other end of connecting line 8 is welded on the ground 10 of the application system of touch-screen cooperating, also promptly with touch-screen the ground 10 of LCD MODULE 9 on.
The another kind of method on ground 10 that transparent conductive film layer 5 is connected to the application system of touch-screen cooperating is: the one side that is coated with transparent conductive film layer 5 on the touch-screen is bonded on the chase of LCD MODULE by conducting resinl, and chase itself is connected to the ground 10 of LCD MODULE by wiring board.
Adopt the beneficial effect of the electric resistance touch screen of band screen layer of the present invention to be further specified by following application case.
Case 1: the application of touch-screen aspect the location.
This application scheme is: a bit motionless by keeping felt pen to click on the touch-screen, touch screen controller reads in the coordinate figure of clicking point, and coordinate figure is presented on the LCD.
When adopting common touch-screen, owing to there is the interference of outer bound pair touch-screen, the data that the controller of touch-screen reads in are differences all at every turn, and the coordinate figure of the clicking point of screen display is also changing always;
When adopting the electric resistance touch screen of band screen layer of the present invention, the data that the controller of touch-screen reads in are identical at every turn, and the coordinate figure of the clicking point of screen display also remains unchanged.
Case 2: the application of touch-screen aspect hand-written.
This application scheme is: by drawing lines on touch-screen, touch screen controller reads in the stroke motion, and lines are presented on the LCD.
When adopting common touch-screen, because the interference of luminotron, as shown in Figure 3, the lines of screen display are having many bends or curves;
When adopting the electric resistance touch screen of band screen layer of the present invention, as shown in Figure 4, the lines linearity of screen display is very good.
