Abstract
Disclosed is a liquid crystal panel driving circuit and a liquid crystal display device. The driving circuit includes a power integrated circuit module, a timing control module, a compensation module, and a temperature sensor. In the driving circuit, the power integrated circuit module and the timing control module adjust a DC low voltage or a clock signal according to a compensating parameter and then output the adjusted DC low voltage or clock signal to a liquid crystal panel. In this way, a working voltage and a working temperature of a TFT in the liquid crystal panel can match each other, whereby the reliability of the liquid crystal panel is improved.
