1. A method of lighting a liquid crystal display, comprising: calculating a luminance for a plurality of pixels in an image in a liquid crystal display (LCD) based upon a light spread function and a brightness value of light emitting diodes (LEDs); changing the brightness value of one or more LEDs based upon a consideration of a gray value of the plurality of pixels and luminance generated by other LEDs; performing iterative steps for changing the LED brightness values to successively cover a pixel gray value of the plurality of pixels; and setting the brightness value of the LEDs to a brightness value substantially greater than or equal to a gray value of a majority of the pixels of the image.
