Oxide（ITO）Film disconnected by particle fulcrum, when user uses pen tip or finger tip squeeze film, and make its recess, and it is another
One block film is connected, then by the variation of pressure on detection, axis, calculates corresponding pressure spot, complete the determination of coordinate.Current four
Line pure-surface electric resistance touch screen mainly uses outer layer PET process black ink, prints silver paste circuit structure on middle layer ito thin film
At upper layer circuit, ito glass printing silver paste railway superstructures lower layer of lower layer circuit, this three layers by OCA or adhered by double sided plaster one
It rises, realizes touch screen function, have 5-7 layers on general structure, every layer of printing processing is cumbersome, and complex procedures, product cost is higher, good
Rate is relatively low.204009852 U of grant number CN disclose a kind of five wire resistive touch screens, and touch screens structure is reduced to bilayer
Structure, improves the light transmittance of touch screens, but excessively thin touch screens cause it is fragile.
Utility model content
