DRIVING APPARATUS AND DRIVING METHOD FOR LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a driving apparatus and a driving method for a liquid crystal display which prevent a residual DC component from flowing in a liquid crystal. SOLUTION: The apparatus is equipped with: a liquid crystal display panel that has liquid crystal cells at each intersection of a plurality of gate lines and a plurality of data lines; an image signal processor which separates a television image signal from a complex image signal supplied from the outside and converts a polarity of the television image signal in response to a polarity inversion signal; a data driver for supplying the television image signal supplied from the image signal processor to the data lines; a gate driver for driving the gate lines in response to a gate control signal; and a timing controller that generates the gate control signal for time-dividing the plurality of gate lines to sequentially drive them during one horizontal period and drives the gate lines during one horizontal period and then applies it to the gate driver, and generates the polarity inversion signal inverted for each one horizontal period and then applies it to the image signal processor.
