Abstract
A driving method and apparatus for a liquid crystal display stabilizing variations in the brightness of a back light dependent upon brightness components extracted from data to be displayed are disclosed. In the method, the brightness components of each frame are arranged into a histogram, which is divided into a plurality of brightness areas. The most-frequent value of the brightness components or the average value of the brightness components is extracted. The brightness of a back light is controlled to correspond to the brightness areas to which the extracted most-frequent value or the average value belongs. One or more particular areas within the brightness areas are selected such that if the extracted most-frequent value or the average value belongs to the particular areas, the brightness of the back light may not be changed in successive frames.
