A LCD panel driving circuit, comprising a gate driver for outputting a scan signal, a data driver for outputting a video signal, a switch circuit, and a temperature sensor. The temperature sensor detects the operating temperature of the LCD panel to determine whether or not the detected temperature is over a switch temperature and produces a selection signal. The switch selects a 1-line dot inversion control signal or a 2-line dot inversion control signal according to the selection signal and outputs a polar control signal, thereby controlling the selection of the outputted video signal polarity.
