Abstract:
A display panel drive circuit is provided with a first display output terminal to be connected with a data line of a display panel, first and second output stages, and a control circuit. The first output stage is directly connected with the first display output terminal and configured to output a data signal with the positive polarity with respect to a standard voltage level. The second output stage is also directly connected with the first display output terminal and configured to output a data signal with the negative polarity with respect to the standard voltage level. The control circuit controls the first and second output stages so that one of the first and second output stages is selectively activated while the other of the first and second output stages is deactivated.
