44.5: Dynamic Wide‐Color‐Gamut RGBW Display

Abstract LCD displays with an additional white primary (RGBW displays) have some clear advantages over conventional RGB displays. Firstly, they can transmit 50% more light and secondly they can have 50% more resolution compared to a conventional RGB display. RGBW displays also have a clear disadvantage; the display gamut does not match with the standard three‐primary (RGB) input gamut. Up to now, this resulted in rather poor color rendition of such displays, which prevented mass‐introduction in the (high‐end) LCD‐TV market. This paper presents the Philips Dynamic Gamut concept that solves the color rendition issues and describes the technical details of a 26″ demonstrator that proves the concept.
