Abstract:
A touch type electrophoretic display apparatus, including: at least one photo-controlled voltage source, used for generating at least one reference voltage, wherein the level of the at least one reference voltage gets lower/higher as the intensity of environmental light increases/decreases; and a plurality of photo sensing circuits, each of which including: a photo transistor, generating a channel current according to an incident light; a light intensity storing capacitor, used for integrating the channel current to generate a photo sensing voltage; and an output switch, used for providing an output signal.
