Abstract
A driving apparatus and a method for driving a display panel thereof are provided. The driving apparatus includes an output buffer, a switch, an adjusting circuit, a digital-to-analog converter and a code detecting unit. The output buffer provides an output voltage to a load according to a static current determining a speed of the output voltage reaching a target voltage for driving the load. The switch is coupled between the output buffer and the load in series, and is turned on or off according to a control signal. The code detecting unit detects an input code. The adjusting circuit determines whether the input code varies when the control signal is enabled, and disables a high driving ratio signal when the input code does not vary when the control signal is enabled. An enabling period of the high driving ratio signal is different from an enabling period of the control signal.
