Abstract

A display device which transmits display data to drive circuits which drive a display panel using low voltage differential signals have input circuits which are hardly influenced by noise. To transmit the low voltage differential signals under the same condition, low voltage differential signal lines are formed in a zigzag pattern so as to make the lengths of the lines equal. To reduce the influence generated by the overlapping of the zigzagged low voltage differential signal lines and the drive circuits, level shift circuits are provided to the input circuits so as to make the input signals assume a stable operation level.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a display device in which a transmission method for supplying display data to a driver IC mounted on the display device is optimized. It also relates to a display device that employs a new signal transmission circuit to reduce noise and save power. Background technique [0002] Liquid crystal display devices of the STN (Super Twisted Nematic) system or the TFT (Thin Film Transistor) system are widely used as display devices of personal computers and the like. These display devices have a liquid crystal display and a drive circuit for driving the liquid crystal display. [0003] Also, in such a liquid crystal display device, the driver circuit is formed as an integrated circuit on a silicon chip different from the liquid crystal display. A silicon chip forming a semiconductor circuit is mounted on a liquid crystal display. As a method of mounting a silicon chip, there are kn...
