摘要： A liquid crystal display device and a method for improving a color reproducibility thereof, detects a gray scale value in applied image information that reduces a color reproducibility of a liquid crystal display device by measuring a gray scale level of a color displayed on a liquid crystal display panel while increasing the gray scale value of the color, and storing a maximum value of the gray scale level is displayable prior to reducing the color reproducibility. The applied image information is compensated to prevent reduction in the color reproducibility.

摘要： An image quality analysis method and an image quality analysis system for a display device are provided. The image quality analysis method for a display device includes the steps of outputting an image pattern for analysis of an image quality of the display device, dividing a screen display region to which the image pattern is output into a plurality of sub-regions, producing measurement data representing the image quality with respect to each of the plurality of sub-regions, arranging the produced measurement data as a time series, obtaining a fractal dimension exponent from the data as a time series, and evaluating the fractal dimension exponent as a level of uniformity of the image quality of the display device.
