Abstract: The International Telecommunications Union Radiocommunication Sector has recommended a broadcasting standard Recommendation ITU-R BT.2020 (Rec. 2020) for ultrahigh-definition television that is aimed at providing a better visual experience. It recommends a color gamut that exceeds previous broadcasting standards and is only achievable by laser-based display technologies. Quantum dot (QD)-enabled liquid crystal displays (LCDs) provide one alternative with potential to meet Rec. 2020's standard color gamut while taking advantage of existing manufacturing capacity. We examined how existing QD and LCD technology could be optimized to meet the Rec. 2020 color standard. Our analysis revealed that up to 94% gamut coverage can be achieved.

James Hillis
bio
James Hillis is a vision scientist in the Display Materials and Systems Division at 3M. He completed a Ph.D. in vision science at University of California, Berkeley, studying 3D shape perception before working on questions related to color perception as a post-doctoral fellow at the University of Pennsylvania. Prior to joining 3M, he worked as a faculty member at the University of Glasgow, where his research focused on social judgment and decision-making.
John Van Derlofske
bio
John Van Derlofske received a Ph.D. in physics from the University of Alabama in Huntsville, where his thesis work concentrated on illumination systems design. After graduation, he worked as head optical designer for Chrysler, developing automotive lighting and illumination systems. Van Derlofske spent the next eight years at Rensselaer Polytechnic Institute, heading the Transportation Lighting Group at the Lighting Research Center. His responsibilities included research, curriculum development, and teaching graduate-level courses in lighting technology and design. Over the course of his academic and professional careers, Van Derlofske has authored 90 publications and given more than 50 presentations at national and international venues. Currently, Van Derlofske is a senior research specialist in 3M's Optical Systems Division Laboratory, where he works on the design, manufacturing, and application of light control films that make LCD displays brighter, more colorful and more efficient.

Although participants were instructed to choose the image they preferred, many observers, without prompting, reported that images rendered in the two gamuts were virtually impossible to distinguish toward the end of the experiment. This suggests that the instruction to choose the image they preferred produced near-threshold values. EXTERNAL
