Abstract:
1. A liquid crystal display comprising: a display panel, which displays an image corresponding to a primary image signal, which includes a first image signal, a second image signal and a third image signal; a light-emitting unit, which supplies light to the display panel; and a timing controller, which receives an input comprising the primary image signal, and outputs a converted image signal, wherein the timing controller converts each of the first image signal, the second image signal and the third image signal on a basis of whichever one of the first image signal, the second image signal and the third image signal is selected, and outputs the converted image signal, and wherein the light-emitting unit determines a luminance of the light supplied to the display panel according to a reference grayscale of a reference image signal, the reference image signal being selected based on a maximum grayscale among the first image signal, the second image signal and the third image signal, wherein the first image signal is a red image signal, the second image signal is a green image signal and the third image signal is a blue image signal, wherein the timing controller supplies a light data signal which controls the luminance of the light, the light data signal having a first duty ratio, the first duty ratio being less than a second duty ratio and corresponding to the reference grayscale of the reference image signal, and wherein the luminance, when selected by application of the first duty ratio to the maximum grayscale, is substantially the same as a reference luminance selected by application of the second duty ratio to the reference grayscale.
