Abstract: A driving apparatus of a display is disclosed. The driving apparatus includes a digital-to-analog converter (DAC) circuit, an output buffer circuit and a pre-charge circuit. The DAC circuit receives a display data with a digital format for generating a gray level voltage. The output buffer circuit is coupled to the DAC circuit, and has an output terminal to output an output signal. The output buffer circuit receives the gray level voltage and the output signal, and compares the gray level voltage and the output signal to generate a comparison result. The pre-charge circuit is coupled to the output buffer circuit, and generates a pre-charge output signal to the output terminal of the output buffer circuit according to the comparison result and a pre-charge enable signal.
