Abstract
In one form, an optical touch screen system includes a semiconductor body forming a hybrid display and image sensor comprising a plurality of display pixels interspersed with a plurality of image sensor pixels, a spatial light modulator overlying a surface of the hybrid display and image sensor, and a control circuit for driving the plurality of display pixels with a first pattern and measuring a second pattern of the plurality of image sensor pixels, the control circuit analyzing the second pattern to detect a position of an object and selectively detecting a touch location in response to the second pattern.
