LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid crystal display device is provided to output a proper gate high voltage corresponding to surroundings temperature. CONSTITUTION: A liquid crystal panel(102) comprises a plurality of gate lines and plurality of data lines. A liquid crystal panel displays an image. A gate driver(104) supplies a gate output voltage to a plurality of gate lines. A data driver(106) supplies a data signal to a plurality of data lines. The data signal corresponds to the image. A power supply unit(110) generates a driving voltage of a first and second gate high voltage, a gate low voltage, and gate and data drive voltage. A gate high voltage output unit(112) senses the surroundings temperature. The gate high voltage output unit outputs the divided gate high voltage to a gate driver.
