Description
Technical field
The utility model relates to touch screen technology, particularly a kind of contact panel and electronic equipment.
Background technology
At present, classify from the technology that adopts, the kind of touch-screen mainly comprises: electric resistance touch screen, surface acoustic wave touch screen, infrared touch panel and capacitance touch screen.
Wherein, electric resistance touch screen has developed into five wire resistive touchscreen from the four-wire ohm touch-screen, no matter be four-wire ohm touch-screen or five wire resistive touchscreen, it all is a kind of touch-screen that is not affected by the external environment fully, in other words, they are not afraid of dust, steam and greasy dirt, can touch with any object, can be used for the drawing of writing.Electric resistance touch screen relatively is fit to the use of limited people in industrial control field and the office.The shortcoming of electric resistance touch screen is: because the skin of the laminated film of touch-screen adopts plastic material, therefore exert oneself excessive or use sharp instrument to touch to scratch whole touch-screen, thereby cause touch-screen to be scrapped.
The principle of surface acoustic wave touch screen is: utilize ultrasound wave in the propagation of dielectric surface, when object contact was arranged, energy and the shape of sound wave changed, thus perceived position, in addition, the variable quantity of all right the 3rd direction of perception of surface acoustic wave touch screen.Surface acoustic wave touch screen can bear the excessive touch of exerting oneself, and therefore comparatively is adapted at the public place and uses.
The design of infrared touch panel is comparatively simple, luminous point is installed apart from frame-saw at display, and arranges infrared emission tube and receiving tube at luminous point apart from four limits of frame-saw, forms an infrared net in screen surface.When user's finger touch is some to certain of screen, can block anyhow two infrared rays through the position, touch point, processor just can be calculated the position, touch point immediately.Infrared touch panel is not subjected to the interference of electric current, voltage and static, is suitable for using under some rugged environment condition.The major advantage of infrared touch panel be cheap, easy for installation, do not need touch-control integrated circuit (IC, Integrated Circuit) or other any controller, can be used on the electronic equipment of various class.But luminous point is damaged easily apart from frame-saw, and maintenance cost is higher.
Capacitance touch screen can be divided into two kinds of surface capacitance touch-screen and Projected capacitive touch screens, and Projected capacitive touch screen can be divided into two kinds of self-capacitance touch screen and mutual capacitance touchscreens.Wherein, self-capacitance touch screen can not accurately identify the position when multiple point touching is arranged, and therefore can have the problem of ghost point, and in other words, self-capacitance touch screen is difficult to realize real multiple point touching.And mutual capacitance touchscreens can be realized multiple point touching, when multiple point touching is arranged, can accurately identify the position that is:.
In traditional mutual capacitance touchscreens, to judge that in order realizing touching block electrode like this, can reduce the jamproof ability of touch-screen in occupation of most spaces, thereby to affect the accuracy that the touch point is detected.In addition, block electrode also can cause the light transmission rate of pixel cell lower, and then can reduce the whole transmitance of touch-screen, so, can increase the energy consumption of touch-screen.
