Patent ID: 7075505

Claim:
A liquid crystal display device comprising: a liquid crystal cell which forms an image display area on a substrate; and a driver for applying a voltage to said liquid crystal cell based on an input video signal, wherein said driver includes a plurality of driver ICs that are mounted on said substrate and a plurality of signal lines, each of the signal lines passing through each of the driver ICs in series, wherein said driver ICs are cascade-connected in series using said signal lines, and wherein the driver receives a digital packet signal including said input video signal and each driver IC includes a controller for generating a mask signal to mask video data output from the driver IC and for transmitting a wait bit block to a succeeding driver IC in said series; and wherein said plurality of driver ICs are cascade-connected to a power feed line via a metal layer inside of each of said driver ICs; and wherein: during reception of video data, each driver IC transmits the wait bit block to said succeeding driver IC; and during reception of the wait bit block, said succeeding driver IC does not process any video data and waits to receive video data from said each driver IC.
