Abstract
Disclosed are a liquid crystal display and a method of the liquid crystal display. The liquid crystal display includes a liquid crystal panel, a backlight unit that supplies light to the liquid crystal panel and has a plurality of light sources, and an image calibration unit that calculates a global dimming resultant value and a local dimming resultant value for an image data signal inputted to the liquid crystal panel, analyzes an average picture level for each block with respect to the image data signal, and determines a convex combination parameter based on the global dimming resultant value, the local dimming resultant value, and the average picture level to generate a calibration dimming value for the backlight unit and an image calibration value for the image data signal.
