4 wire resistive touch panel

How it works :　　　　　4-Wire resistive touch screen is the preferred solution for low cost applications. It consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film). The two layers are suspended by many very small spacer dots.When a certain point is touched, the top layer contacts the bottom layer and a voltage charged by the controller is applied to the bottom layer's electrodes. The coordinate X axis of the touch point can be detected by measuring the voltage value thru the top ITO layer and the coordinate Y axis of the touch point can be detected in the same way by changing voltage input to the top layer's electrodes.Specification:　　　　　Circuiting Rating:5V DC, 35mASurface Hardness:3H　Light TransmissionFilm+Film>77%Hitting Life Expectancy:Over 1 million　Film+Glass>83%Scoring Life Expectancy:Over 100,000　Contact Bounce:<10msOperating Temperature:-10 °C +60 °C　Resolution:4096x4096Storage Temperature:-20 °C +70 °C　Linearity:1.5%（<1.0% By Request）Choices of Glass Thickness:0. 7/1.1/2.0/3.0/0.55mmOperating Force:10g 100gChoices of Glass:Normal/Chemically strengthenedHighlight & Benefit:　　　　Input flexibility finger (with/without glove), stylus, pen, credit card.　FPC tail technology surpasses those of our competitors.　FPC has lower resistance and is more flexible than PET or ITO film used by other suppliers.　Excellent optical performance even with anti-glare hard coating film.　Capable of handling spacer dots diameter less then 0.035mm (smallest in the industry).　Haze < 6% (best optical performance in the industry).　Various choices of surface treatments available.　Anti-Newton ring, anti-glare, special chemical hard coating,anti-reflection.
