ABSTRACT:
There is provided a display device which enables both a full color moving image display (analog mode) and a shallow depth still image display (digital mode), and which achieves a significant reduction in the energy consumption of the display device system including the external LSI. Each of the pixel elements of the display device has two different display circuits corresponding to the respective display modes and a switching circuit for selecting one of them. When the digital mode is selected, the supply of the voltage power to the circuits not required to operate (a DA converter, a operational amplifier and a timing controller) under the mode is halted for reducing the consumption of the electric power by the display device.
