An image presentation device (100) includes a set of color light sources (122, 124, 126) and a micro-display panel (150) capable of operating in both image processing and non-image processing modes. A sensor (170) is coupled to the micro-display device (150) to convert light received from the light source (122, 124, 126) into a signal value representing the output from the light source (122, 124, 126). A controller (110), responsive to the signal value, selectively and/or collectively varies the input to each of the individual light sources (122, 124, 125) to provide for consistent operating performance over the life of the product.
