Method, system and apparatus for power saving backlight

A system for producing an image with a liquid crystal display, comprising:

• a plurality of pixels that display an image on a liquid crystal display;
• a backlight having a plurality of LEDs that light the liquid crystal pixels;
• a processing unit with an access to the image data to be displayed;
• and
• an LED driver circuit which receives LED control signals from the processing unit that condenses a plurality of pixel gray values to a concentrated pixel, assigns the concentrated pixel assigned to a geometric position on a display described by at least one of a plurality of parameters and gray value, forms the concentrated pixels to a condensed image, resolves a light spread function of a first LED in substantially the same resolution as the condensed image, calculates a backlight needed based on the condensed image, and optimizes a value of a plurality of LEDs by considering the contribution of the plurality of LEDs on the concentrated pixel, wherein light spread functions of the LEDs are used.
