Three dimensional liquid crystal display device and method for driving the same

摘要

Disclosed is a three dimensional liquid crystal display device (3D LCD device) which facilitates to improve a picture quality of a three-dimensional image (3D image) by color and luminance corrections, and a method for driving the same, wherein the device comprises an image data analyzer which analyzes a luminance level for each of R, G, and B colors of original image data inputted to display the 3D image; an image data converter which generates color correction data for adjusting a color balance of the R, G, and B colors distorted by the shutter glass, and generates gamma correction data for compensating a luminance reduction, on the basis of luminance analyzing results provided from the image data analyzer; and a timing controller which converts the input image data into image data of a frame unit, reflects the color correction data and the gamma correction data in the image data of the frame unit, and supplies the corrected image data to a data driver.

1. A 3D LCD device for displaying a 3D image through the use of shutter glass comprising:
an image data analyzer, which analyzes a luminance level for each of R, G, and B colors of original image data inputted to display the 3D image; an image data converter a color converting unit, which generates color correction data for adjusting a color balance of the R, G, and B colors distorted by the shutter glass, on the basis of luminance analyzing results provided from the image data analyzer; a gamma converting unit, which generates gamma correction data for compensating a R, G, and B luminance reduction by the shutter glass, on the basis of luminance analyzing results provided from the image data analyzer; and a timing controller, which converts the input image data into image data of a frame unit, reflects the color correction data and the gamma correction data in the image data of the frame unit, and supplies the corrected image data to a data driver, wherein the gamma converting unit increases R, G, and B luminance to a level of the original image data by using the gamma correction data, wherein the color correction data is generated to relatively lower the luminance level of the red and green colors, and generated to relatively raise the luminance level of the blue color based on different values of R, G, and B colored light transmittance of the shutter glass such that a color balance of R, G, and B colored lights of the 3D image transmitting through the shutter glass in gray scale is maintained with respect to a color balance of R, G, and B colored lights of the original image data in gray scale.
