Abstract

The utility model provides a 5-wire resistive touch screen with high stability and accuracy. A layer of transparent oxidized metal conducting layer is arranged on an internal surface of a piece of flat plate glass and is connected with a silver paste electronic circuit with a curing agent, a conducting film is covered on the electronic circuit, and an isolating point is arranged between the electronic circuit and the inner surface of the conducting film. A user inputs a signal instruction by touching the outer surface of the conducting film and a controller of the touch screen calculates the acquired signal instruction and inputs to the CPU, thereby realizing the function of a simulate mouse.

Description

A kind of possess high stability and high-precision five wire resistive touchscreen

Affiliated technical field

The utility model relates to a kind of touch-screen, and especially a kind of possess high stability and high-precision five wire resistive touchscreen.

Background technology

In people's life, often all need to obtain relevant information at present by display screen, computing machine, mobile phone, televisor is all originated as main information, simply and efficiently man-machine exchange message system also more and more is subject to people's attention, therefore touch-screen is liked by people also extensively, resistive touch screen is simple because of principle, cost of manufacture is low and widely-used, but since adopt common silver-colored pulp material as electronic circuit thereby make the resistance value instability, and the instability of resistance value has also just directly influenced the touch stability and the precision of touch-screen, thereby make and produce skew between touch value and the actual result, drift, touch inaccurate, problems such as input broken string, this touch-screen also is subject to the field of employment influence, makes troubles for people's use.

Summary of the invention

In order to solve the not enough problem that existing touch-screen exists, this reality be novel to provide a kind of five wire resistive touchscreen that possess high stability and precision, and this touch-screen not only can conveniently be realized man-machine message exchange, and stable and precision is all higher.

The technical scheme that its technical matters that solves the utility model adopts is: layer of transparent oxidized metal conductive layer is set on the sheet glass inner face, metal conducting layer is connected with the silver slurry electronic circuit that contains hardening agent, the top covering conductive film of electronic circuit, and between the inside surface of electronic circuit and conductive film, be provided with isolating points, the endosexine of conductive film is a conductive layer, extexine is an insulation course, is provided with isolating points between conductive film and electronic circuit.People are when touching the extexine of conductive film, isolating points between extexine and the electronic circuit is extruded, cause conductive film to be connected and produce signal with electronic circuit, touch screen controller is imported CPU after the signal instruction that collects is calculated again, thereby realize the function of analog mouse, reach man-machine message exchange purpose.

The beneficial effects of the utility model are: improved the stability of touch-screen and touched precision, simultaneously touch drift phenomenon and touch-responsive time have also been reduced, can be widely used in stability and the high field of accuracy requirement, product structure is installed simply, is easy to daily operation and maintenance.
