Patent ID: 7123231

Claim:
A driving circuit for a liquid crystal display, comprising: a positive polarity operating circuit having a positive polarity feedback amplifier which receives an input voltage of a positive polarity which increases/decreases in a positive direction from a predetermined reference voltage and outputs a voltage of a value which is equal to said positive polarity input voltage to a signal line that is connected; and a negative polarity operating circuit having a negative polarity feedback amplifier which receives an input voltage of a negative polarity which increases/decreases in a negative direction from said predetermined reference voltage and outputs a voltage of a value which is equal to said negative polarity input voltage to a signal line that is connected, wherein a discharge accelerating unit which accelerates a discharge of a capacitive load of said signal line when said positive polarity input voltage decreases is provided for said positive polarity operating circuit, and a charge accelerating unit which accelerates a charge to a capacitive load of said signal line when said negative polarity input voltage decreases is provided for said negative polarity operating circuit.
