Abstract
In a display driver circuit, a push-pull circuit is coupled to an internal circuit, a first external power terminal, a second external power terminal and a target node respectively, and can control the on-off of the first external power terminal, the second external power terminal and the target node in response to a target control signal transmitted by the internal circuit. The switching circuit is coupled to the target node and the I/O interface of the display driver circuit respectively, and can transmit an electric potential of the target node to the I/O interface of the display driver circuit, that is, a first power signal transmitted from the first external power terminal to the target node or a second power signal transmitted from the second external power terminal to the target node is further output to the I/O interface.
