Abstract
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.
