Abstract

A driving device of a liquid crystal display (LCD) utilized for preventing noises of a clock signal from causing error operation of a shift register is disclosed. The driving device includes a shift register, a reception terminal, a noise elimination circuit and a control signal generation circuit. The reception terminal is utilized for receiving a first clock signal. The noise elimination circuit is coupled to the reception terminal, and is utilized for eliminating noises of the first clock signal and delaying the first clock signal for a preset time to generate a second clock signal. The control signal generation circuit is coupled to the reception terminal, the noise elimination circuit and the shift register, and is utilized for generating a first control signal and a second control signal to control the shift register.
