Patent ID: 7612748

Claim:
An information processing apparatus for controlling driving display means having a transistor disposed in each pixel for switching between conduction and non conduction in response to an applied voltage and outputting a signal in response to a light reception, comprising: control means for controlling a voltage applied to said transistor to switch between display driving and photo detection driving of each pixel; detecting means for detecting an external input in accordance with a signal output upon reception of light by said transistor disposed in a pixel performing light reception driving under control of said control means, wherein said control means displays a detection area constituted of a plurality of pixels performing light reception driving on said display means, by controlling a voltage applied to said transistor, focusing means for focusing an object positioned away from a surface of said display means upon the pixel constituting said detection area, said focusing means including a lens positioned between said object and said detection area, and said detecting means detects as the external input an image of said object focused by said focusing means on the pixel constituting said detection area.
