COMMON VOLTAGE SUPPLY CIRCUIT OF A LIQUID CRYSTAL DISPLAY DEVICE ADDING A DATA LINE OF 50 WITHOUT ADDING A GATE LINE

摘要

PURPOSE: A common voltage supply circuit of a liquid crystal display device is provided to improve a charging characteristic by receiving the common voltage through a data line at a pair of sub pixels adjacent to an IPS mode liquid crystal display device.;CONSTITUTION: A timing controller(41) outputs a gate control signal and a data control signal. The timing controller rearranges the sampled data and outputs the rearranged data after sampling the digital pixel data. A gate driver(42) supplies a gate signal to each gate line of a liquid crystal panel according to a gate control signal. A data driver(43) supplies a data signal to each data line of a liquid crystal panel according to a data control signal and supplies the common voltage to two adjacent sub pixels on each horizontal line through one additionally arranged line per two data lines. A liquid crystal panel(44) receives the common voltage of two sub pixels through the additionally arranged line and the pair of common voltage transistor.;COPYRIGHT KIPO 2010
