Patterned resistive touch panel
A touch panel having a first panel and a second panel, wherein the first panel has a voltage providing area connected to a power source and the second panel has a patterned resistive element facing the voltage providing area so that when a touch event on the touch panel occurs, the first panel is caused to make contact with and provide a voltage to the second panel at one or more contact points on the resistive element. By measuring the voltage on one or both ends of the resistive element, it is possible to determine the two-dimensional coordinates of each contact point. The touch panel can have one or more resistive elements located at different touch areas for sensing one or more touch points in a touch event.
