  • Use of resistive touch screen as a proximity sensor
    Patent number: 8963858
    Abstract: An apparatus and method for the use of a resistive touch screen as a proximity sensor. The touch screen operates in a touch sensing mode and a proximity sensing mode. The proximity sensing mode turns off the touch sensing circuit and uses the equivalent capacitor formed by the top layer of the touch screen with a nearby object to detect proximity. A control circuit selectively connects the touch screen with measurement circuits to perform each of the sensing functions. The control circuit can be implemented with timing based control or an event driven topology.
