touch panel

Product Description

*-Wire resistive touch screen is the preferred solution for low cost applications. It(touch panel) 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 to the top layer's electrodes. touch screen specification 1) Circuiting Rating: 5V DC, *5Ma. 2) Surface Hardness: 3H. 3) Light Transmission: Film+Film>*7%, Film+Glass>*3%. 4) Hitting Life Expectancy: Over 1 million. 5) Scoring Life Expectancy: Over **0,**0. 6) Contact Bounce: <*0ms. 7) Resolution: ***6x***6. 8) Linearity: 1.5%(<1.0% By Request). 9) Operating Force: *0g~**0g. *0) Operating Temperature: **0ºC~**0ºC. *1) Storage Temperature: **0ºC~ **0ºC. *2) Choices of Glass Thickness: 0.7mm, 1.1mm, 2.0mm, 3.0mm, 0.*5mm. *3) Choices of Glass: Normal Glass, Chemically strengthened glass
