Abstract
A method and apparatus for driving the data in a liquid crystal display (LCD) panel are presented. The method and apparatus prevent or reduce defects at the boundary between pixel blocks when the pixel blocks are sequentially driven on a block-by-block basis. The method includes applying data signals to a first data block, precharging a second data block that is adjacent to the first data block to a predetermined precharge voltage, and applying data signals to the second data block. The precharging prevents a large voltage difference at the boundary, thereby reducing defects.
