| 1. An impulse driving apparatus, comprising:
a timing controller, for providing a first and a second output enable signals, a first and a second start vertical signals
and a display data;
a data driver, coupled to and controlled by the timing controller, for outputting a normal signal and an auxiliary signal
according to the display data; and
a gate driver, coupled to the timing controller, for receiving the first and the second output enable signals and the first
and the second start vertical signals, wherein:
the gate driver sequentially generates a first scan signal to enable pixels of scan lines in a liquid crystal display (LCD)
panel when the first enable signal is in a disabled state, and the data driver correspondingly outputs the normal signal to
the enabled pixels of each scan line; and
the gate driver generates at least a second scan signal to enable the pixels of a part of the scan lines when the first and
the second output enable signals are simultaneously in an enabled state, and the data driver outputs the auxiliary signal
to the enabled pixels of the part of the scan lines.
