  • Saturation Dependent Image Splitting for High Dynamic Range Displays
    Publication number: 20180366050
    Abstract: Systems, methods, and computer readable media that improve the gamut size for a multi-layer display. Various embodiments receive a color input value indicative of a target display color associated with an input image and determine a color saturation value for the received color input value. Based on the color saturation value, a drive value for a monochromatic modulation panel and a drive value for a color modulation panel may be determined. The various embodiments can then drive the monochromatic and color modulation panel according to the drive values. The monochromatic modulation panel is not modulated until the color modulation panel is driven to full illumination.
    Type: Application
