Apparatus and method for driving liquid crystal display device

An apparatus for driving a liquid crystal display device, the apparatus comprising:

• a liquid crystal panel having a plurality of pixel regions, and configured to display an image;
• at least one gate driver formed at the liquid crystal panel, and configured to drive a plurality of gate lines;
• a data driver configured to drive a plurality of data lines of the liquid crystal panel, set detectable temperatures for different temperature detection time points, detect an ambient temperature at each of the temperature detection time points, and output a gate drive voltage variation signal and a common voltage variation signal in accordance with the set and detected temperatures at each of the temperature detection time points;
• a timing controller configured to arrange image data input from an outside of the apparatus, supply the arranged image data to the data driver, and control the at least one gate driver and the data driver;
• and
• a power supplier to vary levels of a gate drive voltage and a common voltage in accordance with the gate drive voltage variation signal and the common voltage variation signal, and supply the level-varied gate drive voltage and the level-varied common voltage to the at least one gate driver and the liquid crystal panel, respectively.
