Abstract
Disclosed are a temperature compensation circuit for a display panel, a temperature compensation method and a liquid crystal display. The temperature compensation circuit comprises: a temperature detection unit configured to detect a variation in the temperature; a temperature conversion unit configured to convert the detected variation in the temperature into a voltage compensation value; and a compensation signal generation unit configured to process the voltage compensation value to generate a compensation signal. According to the embodiments of the present disclosure, the common electrode voltage of the display panel can be adjusted in real-time when the temperature varies, so that an amount of flickers presented on the display panel with an polarity inversion can be maintained at minimum, and thus a displaying of picture can be more stable and a visual experience of a viewer can be enhanced.
