Because the touch-screen system that prior art provides adopts glass (Glass) as substrate, glass is anti-scrapes the coefficient height, but not anti-falling, frangible, be prone to split; Though have high penetration, the antireflection ability is not good, and the display effect under the high light is not good; And the glass processing procedure belongs to high temperature process.Therefore unreasonable structure, the electric conductivity of the touch-screen that provides of prior art are bad; The artificial pressure that strengthens touch screen surface causes touch screen surface cracked; High light sub-screen display effect is not good, causes the waste of energy consumption; The cost recovery of glass is high; The glass processing procedure belongs to high temperature process, and energy consumption is very big.

Adopt the printed silver line to do the electrode circuit and have following shortcoming:

1, adhesion is lower.Silver-colored line after the printing is easier to come off, and is unfavorable for the processing of subsequent technique, and causes raw-material waste.

2, circuit is meticulous inadequately, and thickness low LCL is thin.The silver-colored line width that prints is minimum to be merely able to reach 0.1mm, and thickness is at 8--12 μ m.Influence for the higher touch-screen of circuit accuracy requirement is sizable like this, and such thickness can make substrate surface produce offset, and the operation of touch-screen is had a negative impact.

3, being subject to surrounding environment influences.Because also have other material in the composition of silver slurry except silver powder, purity is not enough.In manufacturing process and use, all be vulnerable to influence.And the resistance of the circuit that prints is higher, and amplitude of variation is bigger.

4, use amount is big, and the unit price cost is high.

The utility model content

The resistive touch screen that the utility model provides a kind of rational in infrastructure, good conductivity, resistance to compression, anti-ly falls, toughness glass substrate (PC) is recyclable, production cost is low.

To achieve these goals, the utility model provides following technical scheme:

A kind of resistive touch screen; It comprises: last slice with following sheet; Said last slice be bonded on the said down sheet through adhering agent layer; Said last slice comprise successively from top to bottom: anti-scrape hard layer, toughness glass substrate (PC plate), ink coating and first conductive coating, the below of said first conductive coating is provided with the first copper cash circuit.
