Abstract
A display device, under a digital display mode, performs writing of digital image signals into a static memory circuit while a power voltage of about 3V is applied to the static memory with a panel drive frequency reduced from 60 Hz to 20–30 Hz. It is thus possible to output the digital image signal from a frame memory directly to a liquid crystal display panel without using a level shifter.
