Abstract
Device and method for driving a liquid crystal display device where a driving voltage level is varied with the temperature of an operating environment of the liquid crystal display device to improve display quality. The device includes a liquid crystal display panel, gate and data drivers for driving gate and data lines of the liquid crystal display panel, a timing controller for controlling the data and gate drivers, a power source unit for transforming an external power into a rated voltage level required for driving the liquid crystal display device and forwarding the power, and a driving voltage generating unit for adjusting a voltage level of the power transformed thus in conformity with an environmental temperature to generate a positive polarity driving voltage and using the driving, voltage for generating a plurality of driving voltages required for driving units, including the liquid crystal panel, the gate driver and data driver.
