Abstract

Disclosed is an LCD device which facilitates to improve picture quality of two-dimensional (2D) and three-dimensional (3D) images by automatically converting an image driving mode (2D/3D) in accordance with a viewing distance, and a method for driving the same, wherein the device comprises a distance measuring unit which measures a viewing distance between the LCD device and a viewer; an image mode controller which sets a 2D image mode or 3D image mode in accordance with a comparison result between the viewing distance and a preset reference distance; a timing controller which aligns externally-provided image signals in accordance with the 2D image mode or 3D image mode set by the image mode controller, and converts the aligned image signals into image data by frame unit; and a liquid crystal panel which displays an image based on the 2D image mode or 3D image mode.

First claim

What is claimed is:

1. An LCD device for displaying both 2D and 3D images comprising:
a distance measuring unit which measures a viewing distance between the LCD device and a viewer;
an image mode controller which sets a 2D image mode or 3D image mode in accordance with a comparison result between the viewing distance and a preset reference distance to thereby reduce image distortion and visual fatigue of the viewer;
a timing controller which aligns externally-provided image s…
