METHOD FOR DRIVING DATA LINE AND FLAT PENAL DISPLAY USING THE SAME

摘要

A data line driving method and a flat panel display device using the same are provided to reduce power consumption by controlling a data transmission to a driver according to the comparison between generated and stored gray scale data. A flat panel display device includes a flat display panel(100), a controller(500), and a source driver(300). The flat display panel includes pixels(110) which are formed on the cross section of data lines(G1~Gn) and data lines(D1~Dm). The controller sequentially generates gray scale data on the pixels, compares temporary stored gray scale data with the current gray scale data, and generates a selection signal corresponding to the comparison result. The source driver temporarily stores the gray scale data and drives plural data lines according to the selection signal. The controller supplies a selection signal except for the current gray data to the source driver, when the temporary stored gray scale data is the same as the current generated gray scale data.
