Title:
液晶表示装置の駆動装置および駆動方法
Document Type and Number:
Japanese Patent JP4160539
Kind Code:
B2
Abstract:
A driving apparatus for a liquid crystal display that reduces a residual direct current component from flowing in a liquid crystal is disclosed. In the apparatus, a liquid crystal display panel has liquid crystal cells at crossing of gate lines and data lines. An image signal processor separates a television image signal from a complex image signal and converts a polarity of the television image signal in response to a polarity inversion signal. A timing controller generates the gate control signal for time-dividing the plurality of gate lines to sequentially drive them during one horizontal period and driving the gate lines during one horizontal period and then applying it to the gate driver, and that generates the polarity inversion signal inverted for each one horizontal period and then applying it to the image signal processor.
