摘要： A liquid crystal display includes a signal controller having a luminance controller receiving image data from an external graphic source and controlling the luminance of the image data such that the luminance at the gray expressed by a specific data value of the image data is established to be 80 cd/m2, and a gamma converter outputting image data each having a gamma characteristic adapted to a gamma 2.2 curve. The gamma converter output is determined without using a look up table based on at least one difference curve having a linear portion, a quartic portion, and a critical value where the liner portion and the quartic portion intersect. The liquid crystal display further includes a data driver receiving the image data for selecting and outputting gray voltages corresponding to the image data, and an inverter controlling a lamp to emit light with a luminance of 80 cd/m2 or more.

The liquid crystal display further includes a data driver receiving the image data from the signal controller and selecting and outputting gray voltages corresponding to the image data, and an inverter controlling a lamp such that the lamp emits light with a luminance of 80 cd/m2 or more. With the liquid crystal display, the luminance of a backlight is determined to be a specific value larger than 80 cd/m2, and the luminance of the input image data is controlled such that the luminance of the image data at the specific data value is established to be 80 cd/m2. Furthermore, the gamma characteristic of the image data RGB is converted to be adapted to the gamma 2.2 curve required for the sRGB color space. In this way, the sRGB mode is realized with the liquid crystal display.
