LIQUID CRYSTAL DISPLAY DEVICE HAVING DRIVE CIRCUITS WITH MASTER/SLAVE CONTROL

摘要

A liquid crystal display device used in miniaturized portable equipment includes a distribution circuit corresponding to a circuit scale of a drive circuit to cope with a high-definition multi-grayscale display. A liquid crystal display device having a liquid crystal display element and a liquid crystal drive circuit includes a distribution circuit which distributes a drive circuit output to a plurality of video signal lines within one scanning period. The distribution circuit is divided into a plurality of distribution circuits, and control signals are supplied to each distribution circuit from both end portions of the each distribution circuit. When an output part of the drive circuit is configured with a high withstand-voltage output amplifier and a low withstand-voltage output amplifier alternately connected with the distribution circuit, master and slave functions are imparted to the drive circuit allowing the drive circuit to cope with odd-numbered outputs.
