Abstract
A method of driving a liquid crystal display is provided in which the contrast can be selectively emphasized dependent upon the input data. The input data is converted into brightness components and chrominance components. The most-frequent brightness component is extracted from a histogram of the brightness components, and the histogram is divided into regions, which are re-arranged in correspondence with the extracted most-frequent value. The brightness components of each region are then modified using a curve having a slope that is dependent upon the total number of brightness components in the particular region. Data in which the contrast ratio has been selectively emphasized is generated using the modulated brightness components and the chrominance components.
