Abstract
A method of controlling an RGBW electroluminescent display system that receives a three-component input image signal having triplets of intensity values in an image range and a highlight range includes transforming at least one of the triplets having an intensity value within the image range to a four-or-more-component drive signal to produce a luminance less than the sum of the corresponding luminance values of the red, green and blue light-emitting elements and transforming at least one of the intensity values within a triplet having an intensity value within the highlight range to a four-or-more-component drive signal to produce a luminance greater than the sum of the corresponding luminance values of the red, green, and blue light-emitting elements.
