Liquid crystal display using backlight intensity to compensate for pixel damage

A computer program product including computer usable program code embodied on a non-transitory computer readable storage medium for controlling a liquid crystal display, the computer program product including:

• computer usable program code for applying a test voltage to each of a plurality of liquid crystal elements disposed in an addressable array forming the liquid crystal display;
• computer usable program code for detecting an amount of light received at each of a plurality of photosensors while the test voltage is being applied to the plurality of liquid crystal elements, wherein each one of the photosensors is aligned behind one of the liquid crystal elements receiving the test voltage and is logically associated with the aligned liquid crystal element;
• computer usable program code for applying selected voltage levels to each of the plurality of liquid crystal elements in order to display an image;
• and
• computer usable program code for controlling an amount of backlight produced by each of a plurality of backlighting elements in an addressable array while the image is being displayed, wherein each of the backlighting elements is aligned behind one of the liquid crystal elements and is logically associated with the aligned liquid crystal element, and wherein, for at least one of the liquid crystal elements, the amount of backlight produced by the backlighting elements logically associated with the at least one of the liquid crystal elements is controlled to compensate for a difference between the amount of light detected by the photosensor logically associated with the at least one of the liquid crystal elements and the amount of light detected by other photosensors of the plurality of photosensors.
