ABSTRACT:
A multi-gradation liquid crystal display having dual display definition modes that can display both TV pictures and office automation images, both without flicker. Scanning electrodes extend in a first direction. Scanning and non-scanning voltages are selectively applied to the scanning electrodes. Signal electrodes extend in a second direction perpendicular to the first direction. First and second signal voltages are selectively applied to the signal electrodes. A layer of liquid crystal is sandwiched between the scanning and signal electrodes. Mode switching is provided for switching display between a first mode wherein an image is displayed by two-gradation pixels and a second mode wherein an image is displayed by three or more gradation pixels.
