Abstract

A liquid crystal display device includes: a liquid crystal panel including a pixel having red, green, blue and white sub-pixels; a mode selector selecting one from an RGB mode and an RGBW mode as a driving mode; an RGBW mode signal generating part performing a color correction on RGB input data corresponding to the pixel and converting the RGB input data into RGBW data in the RGBW mode; and an output controlling part outputting RGBW output data by performing a gamma conversion on the RGBW data in the RGBW mode and outputting the RGB input data and a W data for turning off the W sub-pixel as the RGBW output data in the RGB mode.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2009-0095562 filed on October 8, 2009, which is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device and a method for driving the liquid crystal display device. Background technique [0003] As information technology develops, various demands on display devices that display images are also increasing. In recent years, flat panel display (FPD) devices such as liquid crystal display (LCD) devices, plasma panel display (PDP) devices, electroluminescence display (ELD) devices, and field emission display (FED) devices have been used. Among various FPD devices, LCD devices have been widely used due to their advantages of light weight, thin profile, and low power consumption. [0004] In general, an RGB type LCD device including red (R), green (G), and blue (B) sub-pixels as a ...
