  • Publication number: 20080088572
    Abstract: A method for controlling luminance of divided backlight block of a liquid crystal display(LCD) includes the steps of: inputting an image; dividing the image into a plurality of blocks according to the backlight blocks; obtaining a weighted color value of each pixel by performing a weighted operation on a maximum color value of each pixel; and accumulating the weighted color values of the pixels in each block, then dividing the accumulated value by the number of the pixels in each block to get an averaged weighting value of luminance of each block. The method further includes a step of establishing a look up table stored the relationship of the plurality of the color values of the pixels and the plurality of weighted color values corresponding to the color values. The method can control the luminance of each divided backlight block of the LCD.
