Abstract
A method and system for updating the colorimetric characteristics of a flat panel display over the display's entire lifetime. An advantage of the present invention is that the useful life and the color accuracy of a flat panel display can be extended. In one embodiment of the invention, an initial set of luminance data of a flat panel monitor is programmed into addressable memory locations within that monitor. Thereafter, the luminance output of the lamps of the flat panel monitor is tracked with luminance or colorimetric measuring devices. According to the present invention, the luminance data are used in determining the correlation between voltage settings of the lamps and the color characteristics of the display such as color temperature. By measuring the luminance of the display periodically, a precise and accurate color profile of the flat panel display can be maintained.
