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

— A high-definition laser TV that employs a newly developed laser light source and a super-wide-angle projection optical system has been developed. This adoption of a laser light source with three primary colors helped to achieve an extremely wide color gamut, and, in addition, a compact optical engine, which has been optimized to the laser light source and contributed to the achievement of the stylish design of a large screen of 65 in., with the depth being only 255 mm.

56.3: 65-inch, Super Slim, Laser TV with Newly Developed Laser Light Sources

A new light source for laser TVs has been developed along with a 65-inch super slim laser TV that employs the light source. In this stylish laser TV set, a depth of 255 mm has been realized owing to the new laser light source, a compact optical engine and a small laser drive power supply which are optimized to the light source.

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.
