Patent ID: 8847931

Claim:
A driving apparatus for a liquid crystal display comprising: a signal modification unit which modifies a signal based on a data signal input to the liquid crystal display, wherein the signal modification unit determines whether the data signal corresponds to an image to be displayed with a quality deterioration and outputs at least one of a first signal and a second signal, wherein the first signal is output which changes a duration of a gate-on signal relative to a time duration during which the data signal is input to be a first interval when the signal modification unit determines the data signal corresponds to the image to be displayed with the quality deterioration, wherein the second signal is output which changes the duration of the gate-on signal relative to a time duration during which the data signal is input to be a second interval when the signal modification unit determines the data signal does not correspond to the image to be displayed with the quality deterioration, and wherein the first interval is longer than the second interval.
