Abstract

A four-primary liquid crystal display (LCD) by hybrid color processing in spatial and temporal domains is presented. By integrating with quantum dots, the number of LED can be reduced and the emission spectrum optimized. This approach exhibits following advantages over conventional three-primary LCDs: 1) it has 1.5X higher spatial resolution and 2X higher light efficiency; 2) it can achieve 130% color gamut in CIE 1931 and 155% in CIE 1976 color space; and 3) it has a more relaxed LC response time requirement and can be readily integrated into commercial LCD products.
