LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF

摘要

A liquid crystal display device and a driving method thereof are provided to prevent an erroneous operation of a gate driver by maintaining high level duration of first and second clock signals irrespective of frame frequency. A liquid crystal display device includes a timing controller(500), a clock generator(600), a gate driver(400), and an LCD(Liquid Crystal Display) panel(300). The timing controller receives a main clock signal and outputs first and second clock generation control signals, where the second clock generation control signal has a variable duty ratio. The clock generator receives the first and second clock generation control signals and outputs first and second clock signals having variable duty ratios and opposite phases. The gate driver receives the first and second clock signals and outputs a gate signal having a variable duty ratio. The LCD panel includes plural pixels which receive the gate signal and are turned on/off to display images.
