Abstract

High Dynamic Range (HDR) and Wide Color Gamut (WCG) displays are now commonly available on the market of TVs. The standard color characteristics are no more adapted for this type of display. In this paper, we use the ICtCp color space recently proposed by Dolby laboratories for new HD video standards to analyze color measurements made with a Fourier optics viewing angle instrument. We evaluate the viewing angle dependence of the color gamut and color volume of two HDR/WCG displays, one QLED TV and one OLED TV. The analysis is also made using the standard L*a*b* color space. The interest of the ICtCp color space for direct comparison of the displays is discussed.
