Image display device and method of driving the same
摘要:
An image display device includes a display portion formed by disposing pixel circuits in a matrix, and a signal line driving circuit and a scanning line driving circuit for driving the pixel circuits through signal lines and scanning lines of the display portion. The pixel circuit includes at least: a light emitting element; a drive transistor for current-driving the light emitting element by a drive current corresponding to a gate-to-source voltage thereof; a hold capacitor composed of either one capacitor or a plurality of coupling capacitors for holding therein the gate-to-source voltage; and a write transistor adapted to be turned ON/OFF in accordance with a write signal outputted from the scanning line driving circuit, thereby setting a voltage developed across terminals of the hold capacitor at a voltage of corresponding one of the signal line.
