Abstract
Official abstract text for this publication.
A method of dynamic of gamut control is provided for a display having a multi-spectral (typically multi-color) backlight, and sub-pixels corresponding to the different backlight spectra and at least one common sub-pixel. The display may f be an RGBW display having an RGB backlight. The method includes iteratively calculating the minimum required backlight intensities that will allow all (selected) color points of an image to be represented by the display. The determination for a light source of the backlight is based on determinations of intensities determined for other light sources in a previous iteration.
First claim
Opening claim text (preview).
The invention claimed: 1. A method of dynamic gamut control for a display having a mum-spectrum backlight comprising a plurality of backlight sources with different spectra common for a plurality of pixels, pixels of the plurality of pixels being formed by a group of sub-pixels, each sub-pixel corresponding to a transmission component illuminated by the multi-spectrum backlight, the transmission components for each pixel having particular transmission spectrums to provide a set of…
