High Dynamic Range (HDR) and Wide Color Gamut (WCG) displays require adapted color measurements analysis. In this paper, 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 measured using a Fourier optics viewing angle system. The analysis is made using L*a*b* color space and ICtCp color space recently proposed by Dolby laboratories. The different interests of the ICtCp color space for direct comparison of the displays is discussed.
We developed a novel projection-type integral threedimensional (3D) display method using multiple projectors and displayed a 3D image with a wide viewing angle. In the proposed method, the viewing angle and positions of light spots that become pixels of a 3D image are controlled by projecting elemental images onto a lens array at a predetermined angle as collimated light beams. By projecting elemental images at different angles from multiple projectors installed at optimal positions, the viewing angle is enlarged, and the resolution is enhanced. We prototyped a projection-type integral 3D display system consisting of five ultra high definition (UHD) projectors with a viewing angle of 40 degrees in the horizontal and vertical directions while having a resolution of 114 thousand dots in the center view. We experimentally verified the display performance of the prototype display system and confirmed the validity of the proposed method.
