ENC can supply the touch panel from 1.2 inches to 22inches. Now our products are well be used for Mobile phone, PDA, POS, GPS and some other equipment. Now we can supply not only the 4-wire resistive touch panel, but aslo the SAW touch panel, 5-wire resistive touch panel.
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 ***cer 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 ***ected by measuring the voltage value thru the top ITO layer and the coordinate Y axis of the touch point can be ***ected in the same way by changing voltage input to the top layer's electrodes.
This specification suit analog resistance touch panel. Which used in LCD module
