    摘要: A driving method and apparatus for a liquid crystal display is provided in which a contrast ratio of data to be displayed can be expanded and the brightness of a back light can be changed using an accumulated result of a plurality of frames. In the driving method, data to be displayed is converted into brightness components and arranged into a histogram for each frame. Second data having an expanded contrast is generated using the histograms of at least two frames, including the histogram of the current frame. Averages of the histograms are calculated and used to control the brightness of the back light. The averages may be weighted such that frames closer to the current frame have a larger effect.

    摘要: A driving method and apparatus for a liquid crystal display uses a comparison between the previous frame and the current frame to expand the contrast ratio and reduce the manufacturing cost. A limited amount of data from the current image may be used: either using a limited area of the image or merely the amount of green in the overall image or the limited area. In the apparatus, an image signal modulator expands the contrast of the input data when the previous image is analogous to the current image to thereby generate output data. A timing controller re-arranges the output data to apply the output data to a data driver.

    摘要: 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.
