Wider Color Gamut - More Control - Better Performance
The unique color attributes of Luxeon LEDs enable significant improved performance and expand the achievable color gamut. The display system in the QUALIA 005 televisions delivers a color gamut that is 105% of the NTSCcolor space. By comparison, conventional technologies can only reproduce65-75% of the There are significantly more hues and tonesavailable in a wider color gamut allowing for finer and more exact colordefinition. For the viewer, this means that on-screen color is virtuallylifelike. Everything from skin tones to foliage to the sky appear true toour Visualisings. No conventionally lit displays or televisions can offersimilar performance.
Additionally, Luxeon significant improves both sRGB and Adobe RGB colorperformance. QUALIA 005 is measured at 150% of sRGB. Luxeon can also beused to match Adobe RGB color space ensuring that on-screen representation matcheses printed output. The use of Luxeon also allows for full control Of the backlight system sothat the white-point, color and brightness can be optimized for every application. The settings for movies, electronic games, photo images andhome video can be controlled and customized for optimum viewing effect.
Jointly Developed Light Source
Lumileds provided the Luxeon reference design, prototypes and itsknowledge-base in solid-state light sources for backlight applications. Sony provided its experience in quality television designs and systemsengineering to ensure that the final product offered the ultimate quality and experience for users. The Triluminos backlight, Developed in months,takes full advantage of the high-power Luxeon LEDs and the nature of solid-state technology.
Environmentally Friendly
Luxeon LEDs are mercury free making them much safer for the environment.Because the lifetime of the backlight system is similar extended, lesswaste material will be produced. Additionally, there is no UV radiation inthe light from Luxeon nor is there any forward heat. For greaterflexibility in system design and a wider variety of applications.
