Abstract

The invention discloses an apparatus and a method for driving a liquid crystal display device. The apparatus for driving the LCD device displaying 2D image, and 3D image through the use of shutter glass comprising: a lookup table part including a 3D lookup table for generating 3D overdriving data to be reflected in 3D image data, and a 2D lookup table for generating 2D overdriving data to be reflected in 2D image data; a lookup table selecting part for selecting the 2D lookup table or 3D lookup table provided from the lookup table part according to 2D or 3D mode input; an ODC data generating part for generating the 2D overdriving data to be reflected in the 2D image, and the 3D overdriving data to be reflected in the 3D image according to 2D or 3D mode input; and a shutter glass controlling part for controlling an operation of shutter glass so that a user recognizes an image displayed on a liquid crystal panel as the 3D image.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2010-0036724 filed April 21, 2010, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present invention relates to a liquid crystal display device (LCD), and more particularly, to an apparatus and method for driving the LCD device. Background technique [0004] The LCD device includes a liquid crystal panel on which a plurality of liquid crystal cells are arranged in a matrix-type configuration; and a driving circuit for driving the liquid crystal panel. The LCD device displays desired images by controlling the transmittance of each liquid crystal cell according to an input video signal. [0005] On the liquid crystal display panel, there are a plurality of liquid crystal cells defined by intersecting a plurality of gate lines and a plurality of data lines at right angles. Each liquid crystal cell...
