19.3: Laser TV: Ultra-Wide Gamut for a New Extended Color-Space Standard, xvYCC

We have developed an HDTV that adopts semiconductor lasers involving three primary colors, red, green and blue for the light source. The adoption of a laser light source helped us realize a HDTV with a dramatically wide color gamut, namely 190% the color gamut of ITR-U BT.709. In addition, we have also developed an LSI that can deal with an 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.
