Abstract: A system and method are provided for measuring the average light levels from a flat panel display for use in a brightness compensating system. One or more photodiodes are disposed outside of the display area of a flat panel display so as to measure the average light levels directly or via total internal reflection through the transparent substrate of the display. The measured light levels are then used to provide a baseline for calibrating the color balance and brightness of the display using the brightness compensating system.
