PURPOSE: TFT(Thin Film Transistor) LCD(Liquid Crystal Display) display is provided to control duty ratio of a gate on enable signal. CONSTITUTION: TFT(Thin Film Transistor) LCD(Liquid Crystal Display) display comprises a timing controller(20) for receiving a timing signal from outer system such as a computer system and outputting various signals such as gate clock and a duty ratio changer(30) for receiving the gate clock from the timing controller(20) and changing the duty ratio of the gate clock according to the user inputting, thereby to output a gate on enable signal. TFT LCD display further comprises a reference voltage generator(40) for generating and outputting reference signals of various voltage such as gate on voltage and a gate driver(50). The gate driver(50) controls reference voltage of the gate on signal output from the reference voltage generator(40) according to the gate on enable signal output from the duty ratio changer(30), and outputs the gate on voltage into the liquid crystal display. Accordingly, duty ratio of the gate on enable signal can be easily controlled by the user, thereby preventing flicker and cross talk.
