The present invention relates to a LCD module and a method thereof. The LCD module includes a gate driver, a liquid crystal display panel having a plurality of pixel units, a temperature sensor for generating a temperature sensing signal based on a temperature of the liquid crystal display panel, and a voltage regulator for adjusting scan voltage according to the temperature sensing signal. The gate driver outputs a scan signal with the adjusted scan voltage to the plurality of pixel units. The LCD module can adjust the scan voltage based on a variety of the temperature of the LCD panel to further change current charging the pixel units, shortening a response time period of the LCD module.
