Abstract:
A liquid crystal display having data driving apparatus comprising first and second output switches, a charge sharing line, and first and second charge sharing switches. The first output switch switches an electrical connection between a first amplifier providing a positive gradation voltage and a first data line in response to a control signal. The second output switch switches an electrical connection between a second amplifier providing a negative gradation voltage and a second data line in response to the control signal. The first charge sharing switch switches an electrical connection between the first data line and the charge sharing line in response to the control signal. The second charge sharing switch switches an electrical connection between the second data line and the charge sharing line in response to the control signal.
