Abstract
An exemplary power supply switching circuit () includes a first input () for receiving a first signal, a second input () for receiving a second signal, a voltage regulating circuit (), and a signal switching circuit (). The voltage regulating circuit includes semiconductor elements () electrically coupled in series. The signal switching circuit includes a first input terminal (), a second input terminal (), and an output terminal (). The first input is electrically coupled to the first input terminal via the first voltage regulating circuit, the second input is electrically coupled to the second input terminal, and the output terminal is configured to be an output of the power supply switching circuit. The first voltage regulating circuit regulates the first signal via the voltage drops of the first semiconductor elements. A flat panel display using the power supply switching circuit is also provided.
