Achieving BT. 2020 Color with LCDs: A Tale of Two Applications

One constraint on a complete transition to the ITU BT.2020 broadcasting standard is the limited availability of displays that achieve the recommended color space. However, several technologies are capable of coming close. Our research addresses the question of how close the primaries must be to the standard to be acceptable for different applications (e.g. professional vs. consumer). In previous research, we measured color difference detection thresholds for colors along the Rec. 2020 boundary with simple test patterns. In our current study, we measured color discrimination rates for photographic images rendered in color spaces near Rec. 2020 in two tasks: (1) images viewed sequentially and (2) images viewed side-by-side. We discuss how to use these data to define tolerance criteria for different applications and examine if prototype quantum-dot enabled LCDs meet these criteria.
