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.

A liquid crystal display device, comprising:
- a liquid crystal panel including a pixel having red, green, blue and white sub-pixels;
- a mode selector that selects one from an RGB mode and an RGBW mode as a driving mode;
- an RGBW mode signal generating part that performs 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 that outputs RGBW output data by performing a gamma conversion on the RGBW data in the RGBW mode and outputs the RGB input data and a W data for turning off the W sub-pixel as the RGBW output data in the RGB mode.
A method of driving a liquid crystal display device having a liquid crystal panel including a pixel having red, green, blue and white sub-pixels, comprising:
- selecting one from an RGBW mode and an RGB mode;
- 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
- 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.
