Patent ID: 7808495

Claim:
A display device comprising: a plurality of gate signal lines disposed in a predetermined direction on a substrate; a gate driver for feeding scanning signals to the gate signal lines; a plurality of drain signal lines disposed in a direction different from the predetermined direction; a drain driver which selects one of the drain signal lines and feeds a digital image signal to the selected drain signal line; a timing control circuit which feeds a timing control signal to the gate driver, the drain driver or both of the drivers; a plurality of pixels disposed on the substrate; a plurality of pixel electrodes which are disposed in corresponding pixels, selected by the scanning signals fed through the gate signal lines and provided with signals corresponding to the digital image signals fed through the drain signal lines; a first display circuit which is provided for each of the pixel electrodes, includes a storage capacitor holding an analog image signal converted from the digital image signal and provides a corresponding pixel electrode with the analog image signal; a second display circuit which is provided for each of the pixel electrodes, includes a retaining circuit holding the digital image signal and provides a corresponding pixel electrode with a voltage corresponding to the digital image signal held by the retaining circuit, each of the pixels including a first display circuit and a second display circuit; a circuit selection circuit for selecting one of the first and second display circuits; and a control circuit halting, after the circuit selection circuit selects the second display circuit, a supply of a power voltage to all DA converter circuits which convert the digital image signal inputted to the analog image signal and are required to operate the first display circuit.
