Abstract
Official abstract text for this publication.
A method and system for adjusting luminance in a display device including displaying an image with saturated colors, and adjusting luminance settings of sub-pixels so that a relative luminance ratio between full white color and any fully saturated color is within approximately 25 percent of a reference relative luminance ratio between the full white color and the same fully saturated color in an equivalent display device including red, green and blue sub-pixels.
First claim
Opening claim text (preview).
What is claimed is: 1. A method in a display device including a plurality of pixels, each pixel comprising at least two sub-pixels, the display device including red, green, blue and white sub-pixels, the method comprising: displaying an image having saturated color, saturated color is color produced by a pixel in which at least one, but not all, primary color settings is less than approximately 25 percent of its maximum value; and adjusting luminance settings of sub-pixels so…
