Patent ID: 7583259

Claim:
A display apparatus having a plurality of display pixels arranged over a substrate, in which, to each of the plurality of display pixels, a gate signal from a corresponding gate signal line and an image signal from a drain signal line provided in a direction intersecting with the gate line are supplied, wherein each of the plurality of display pixels comprises: a first display circuit having a signal storing circuit for storing a digital image signal supplied from the drain signal line in accordance with the gate signal; and a second display circuit provided adjacent to the first display circuit and having a storage capacitor for storing an analog image signal supplied from the drain signal line in accordance with the gate signal and supplying the signal stored in the storage capacitor to a display electrode; and wherein the first display circuit and the second display circuit are selectively switched in accordance with an image to be displayed, a potential of a power source line for supplying a power source voltage to the signal storing circuit of the first display circuit is controlled to be at a low level during a period in which the second display circuit is selected, and when the selection of the display circuit is switched from the second display circuit to the first display circuit, the potential of the power source line is controlled to be at a high level to operate the signal storing circuit; wherein the display apparatus further comprises a driver for driving each of the plurality of display pixels, during a period in which an image in accordance with a digital image signal stored in the first display circuit of each of the plurality of display pixels is displayed in each display pixel, the operation of the driver is halted by stopping voltage supply to the driver, the driver includes a gate driver for controlling the gate signal line, a drain driver for controlling the drain signal line, and a panel driving circuit for controlling the gate driver and the drain driver, and during a period in which an image in accordance with a digital image signal stored in the first display circuit of each of the plurality of display pixels is displayed in each display pixel, the operations of the gate driver, the drain driver; and the panel driving circuit are halted.
