Abstract
Embodiments of the present invention recite a method and system for extending the lifespan of a touch screen assembly. In one embodiment, a signal is received indicating an input pressure is being applied to a touch screen assembly. It is then determined that the input pressure comprises a valid input event and the coordinates of the valid input event are received from the touch screen assembly.
