Implementation of a color calibration method for liquid crystal displays
Abstract
In this paper we describe the implementation of a color calibration method for liquid crystal displays (LCD) where we assume that the angle of vision is normal to the center of the screen. We change the procedure generally used with cathode ray tubes (CRT) and take into account the high intensity black of an LCD, the variable chromaticities of its primaries and the less than perfect additivity of its colors. This is done by modifying the calibration data and using correction tables. We describe three rendering algorithms which can be used with this implementation. We test them on four IBM LCD models produced in the last four years and conclude that the simplest algorithm is adequate for the latest model.
