Abstract:
1. A liquid crystal display comprising: a liquid crystal display panel including a plurality of data lines, a plurality of gate lines intersecting the data lines, and liquid crystal cells respectively formed at intersections of the data lines and the gate lines, and divided into a first area, a second area and a third area; a first data integrated circuit (IC) that drives the first area; a second data IC that drives the second area; a third data IC that drives the third area; and a timing controller that analyzes an input digital video data, generates a first selection signal and a second selection signal for controlling whether charge sharing is used, and independently controls the first, second, and third data ICs using the first and second selection signals, wherein the second area is divided into a first block adjoining the first area, a third block adjoining the third area and a second block located between the first block and the third block; and the first selection signal controls whether the charge sharing is used for the first and third data ICs, and the second selection signal controls whether the charge sharing is used for the second block and controls a charging delay variation so that the charging delay variation is lessened between the second block and the first area or between the second block and the third area in the first or third block.
