Image display apparatus having pixel circuits and driving method thereof |
摘要 |
A pixel circuit (1000) and an image display apparatus are provided making use of a hysteresis characteristics of a transistor (1001) for driving a display element. The pixel circuit (1000) comprises: a transistor (1001) 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 (1002) supplied as a drive current with a current controlled by the transistor (1001); and a capacitor element (1003) connected to a gate electrode of the transistor (1001). 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 (1002) to effect light emission. |
