LIQUID CRYSTAL DISPLAY AND LOCAL DIMMING CONTROL METHOD OF THEREOF

摘要

PURPOSE: A liquid crystal display and a local dimming control method thereof are provided to increase display quality when a 2D or 3D image is formed by a local dimming method. CONSTITUTION: A backlight unit(16) irradiates light on a rear side of a liquid crystal display panel. A backlight driving circuit drives light sources by a predetermined block based on a dimming value per a block. A local dimming control circuit(14) calculates a pixel gain value based on a dimming value per a block of a first frame. The local dimming control circuit applies the pixel gain value in compensating for data of a second frame. The local dimming control circuit makes timing of applying the pixel gain value different to compensate for data according to a mode signal.
