LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid crystal display device is provided to compensate the ripple of a common voltage by reversing a polar signal. CONSTITUTION: A liquid crystal panel(102) comprises a plurality of gate lines(GL1-GLn) and a plurality of data lines(DL1-DLm). The liquid crystal panel displays an image. A gate driver(104) drives a plurality of gate lines. A data driver(106) comprises a plurality of data driver integrated circuits. A plurality of data driver ICs comprises an output channel. The output channel and a plurality of data lines are in one to one correspondence. The date driver drives a plurality of data lines. A common voltage generator(110) generates a common voltage. The common voltage is supplied to the liquid crystal panel. A timing controller(108) controls the gate and data driver. The timing controller turns the polar signal of odd number and even number data driver IC reverse. The polar signal is provided to the data driver.
