摘要:
A source driving circuit includes a buffer amplifier configured to generate a driving signal from an original driving signal. The buffer amplifier includes a first amplifier and a second amplifier. A high-level terminal of the first amplifier is coupled to the first power signal terminal, a low-level terminal is coupled to the second power signal terminal, and an output terminal is configured to output a positive polarity driving signal. A high-level terminal of the second amplifier is coupled to the third power signal terminal, a low-level terminal is coupled to the fourth power signal terminal, and an output terminal is configured to output a negative polarity driving signal. The voltage of the second power signal terminal is less than the voltage of the third power signal terminal.
