Abstract: Methods for displaying an image on a color display having a target display white point luminance and chromaticity, and including three gamut-defining emitters defining a display gamut and two or more additional emitters which emit light within the display gamut; the method including receiving a three-component input image signal; transforming the three-component input image signal to a five-or-more component drive signal; and providing the drive signal to display an image corresponding to the input image signal. One method provides a reproduced luminance value higher than the sum of the respective luminance values of the three components of the input signal when reproduced with the gamut-defining emitters. Another method provides reduced power in an OLED display including a white-emitting layer with three color filters for gamut-defining emitters and two or more additional color filters for three additional within-gamut emitters.

These viewing angles can be in the tip direction, turn direction or in a direction that is some combination of tip and turn.
