Abstract
A control circuit includes a switching circuit and a select circuit. The switching circuit is configured to receive a scan signal, a first switching signal, and a second switching signal, and output the first switching signal and the second switching signal according to the scan signal. The select circuit is configured to receive a first supply voltage, a second supply voltage, the first switching signal, and the second switching signal, and selectively output the first supply voltage or the second supply voltage to a target electrode according to the first switching signal and the second switching signal.
