Abstract
Provided are a liquid crystal display device and a method of performing local dimming of the liquid crystal display device. The method of performing local dimming of the liquid crystal display device includes displaying an image with a single grayscale on a liquid crystal display panel, detecting an abnormal block where a light leakage or a black uniformity (BU) defect occurs among a plurality of blocks of the liquid crystal display panel, and calculating a dimming value for the abnormal block. Accordingly, a dimming value for each area where a light leakage or a black uniformity defect occurs can be calculated independently and the calculated dimming value can be applied to local dimming. Therefore, it is possible to reduce a light leakage and also is possible to address a black uniformity defect.
