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

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.
