Abstract
The present invention provides an EL display adapted to receive a three-color input image signal, including three gamut-defining EL emitters for emitting red, green, and blue colored light and two additional EL emitters for emitting at least two additional colors of light, the chromaticity coordinates of the at least two additional colors of light lying inside the gamut and near the Plankian Locus; a structure for providing a display white point; and a controller responsive, to the provided display white point and the input image signal for providing first separate drive signals for the three gamut-defining EL emitters and second separate drive signals for the two additional EL emitters, wherein the respective luminance values corresponding to the second separate drive signals are each a function of the input image signal and the distances between the display white point and the pseudo-blackbody points of the two additional colors.
