Pixel circuit and image display apparatus having the pixel circuit

摘要

A pixel circuit and an image display apparatus are provided making use of a hysteresis characteristics of a transistor for driving a display element. The pixel circuit comprises: a transistor providing both different first and second relations between a gate voltage value and a drain current value at a transition from off state to an on state, and from the on state transits to the off state respectively; a display element supplied as a drive current with a current controlled by the transistor; and a capacitor element connected to a gate electrode of the transistor. One of the first and second relations is utilized during a first period for setting the drive current to be supplied to the display element. And, the other of the first and second relations is utilized during a second period for supplying the drive current to the display element to effect light emission.
