Abstract
A pixel circuit is disclosed. The pixel circuit includes, at least a drive transistor; an input transistor; a first switching transistor; a second switching transistor; a retention capacity; and an electro-optic device. The retention capacity is connected, at both ends, to a gate node and a source node, respectively, of the drive transistor. The electro-optic device has rectification properties, and is determined in intensity by a value of a drive current coming from the drive transistor whose source node is connected to an anode thereof. The input transistor is connected, at one current end, to the gate node of the drive transistor, and samples a video signal to the retention capacity during a predetermined sampling period. The first switching transistor is turned on before the sampling period, and connects the gate node of the drive transistor at a predetermined reference voltage.
