Abstract
Provided in the embodiments of the disclosure are a common voltage control circuit and method, a display panel and a display device. The control circuit includes a temperature sensing circuit and a voltage adjusting circuit. The temperature sensing circuit is configured to sense the ambient temperature. The voltage adjusting circuit is coupled to the temperature sensing circuit and the common electrode, and is configured to provide a corresponding common voltage to the common electrode based on a temperature signal from the temperature sensing circuit. According to the embodiments of the present disclosure, the common voltage may be changed according to the ambient temperature to improve the image sticking.
