Abstract
An interferometric modulator ('IMOD') display utilizes ambient light and incorporates touch sensing without reducing the amount of ambient light that reaches the MEMS modulators, and without introducing any optical distortion or loss of performance. Electrodes for touch sensing are located at a back glass of the inteferometric display, and are used in conjunction with electrodes whose primary function is to activate the pixels of the MEMS display, in order to sense a touch. The touch deflects the IMOD layers and is sensed through the various display layers at the rear of the display.
