DRIVING APPARATUS FOR LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR DRIVING THE SAME

摘要

PURPOSE: An apparatus and method for driving a liquid crystal display device are provided to improve display quality by setting an optimal charge sharing level. CONSTITUTION: A data switching unit(10) charge shares a plurality of data lines into a preset charge sharing level. A charge sharing unit(14) charge shares each data lines or supplies an image signal to each data line from a data driver(4). A charge sharing controller(12) controls the charge sharing operation of the charge sharing unit. The charge sharing controller supplies a preset charge sharing voltage to the charge sharing unit.
