Patent ID: 7812806

Claim:
A method of driving a liquid crystal display device using n (n is a natural number and satisfies 2≦n) bit digital video signals to display an image, the liquid crystal display device including a source signal line driver circuit, a gate signal line driver circuit, memory circuits, and a plurality of pixels, wherein shift registers in the source signal line driver circuit output sampling pulses, which are inputted to latch circuits, which hold the digital video signals in response to the sampling pulses, the n bits of the held digital video signals being written sequentially in a source signal line, wherein gate signal line selecting pulses are outputted in the gate signal line driver circuit to select gate signal lines in order from the first row, and wherein the n bit digital video signals are written in or read out the plural pixels in order from the first row, wherein, during a still image display period, the n bit digital video signals stored in the memory circuits are repeatedly read to display a still image, so that the source signal line driver circuit can stop its operation.
