3.4: Invited Paper: Laser TV ‐ Ultra Wide Color Gamut in Conformity with xvYCC

Abstract

This paper provides some interpretations of the Laser TV which we have successfully developed [1]. The Laser TV is an HDTV that adopts solid state lasers involving three primary colors, red, green and blue for the light source. The adoption of a laser light source helped us realize an HDTV with a dramatically wide color gamut, namely 190% the color gamut of ITU-R BT.709. In addition, we have also developed an LSI that can deal with the extended color space xvYCC, which is a new international standard, and mounted the LSI in the HDTV. The display of colorful and natural video pictures has been achieved through the effective use of the wide color gamut involved in the laser light source supported by a video signal processing circuit that complies with the xvYCC standard and Natural Color Matrix, a color management technique.

A 65‐in. slim (255‐mm depth) laser TV with wide‐angle projection optical system

“…As a means of obtaining a wider color gamut for display units, we have been developing laser TV sets that use three-primary-color lasers for the light source and have previously released laser TV sets of 52 and 56 in. 3,4 We have worked on this project to develop new laser light sources for laser TVs as well as a small power supply to drive them and a compact optical engine that are all optimized to the laser light source, aimed at the production of laser TVs and eventually to a 65-in. laser TV product, all whose components are housed in a thin enclosure.…”

P‐49: A Gamut‐Mapping Algorithm with Separate Skin and Non‐Skin Color Preference Controls for Wide‐Color‐Gamut TV

“…The advances of flat panel display (FPD) technology are pushing the color gamut of TVs wider and wider towards the boundary of the human visual system [1]. Many LCD TVs in the market are already much wider than sRGB/ITU-R BT.709, the color gamut used by the current HDTV and Internet/computers standards.…”
