1080p LED hybrid laser projector unveiled by ViewSonic
The new projector is targeted towards the pro AV market. In the system, the combination of LED and laser light result in a vibrant and rich display colour
ViewSonic, aglobal provider of computing, consumer electronics and communications solutions, is expanding its professional projector series with the new Pro8300, while previewing its LED hybrid laser technology in the Pro9000.
use,” saysRoger Chien, product manager for ViewSonic.
The Pro8300 professional 1080p commercial grade projector is suited tobusiness data projection. It incorporates ViewSonic’s “BrilliantColorTechnology” with a powerful Pixelworks10-bit image processor for vivid colours, while its 1920x1080 native resolution, 3,000 ANSI lumens and a 4,000:1 dynamic contrast ratio produce razor sharp images that shine in virtually any ambient light environment. Paired with a wide 1.5X optical zoom adjustment for more than 36% additional zooming capability and integrated speakers, the Pro8300 delivers stunning audio and visual experience.
“Full HD resolution has become somewhat of a standard feature across consumer home and cinema entertainment projectors; however, finding hi-def capabilities in a quality yet affordable projector offering for businesses is far less common,” continuesChien. “Our Pro8300 breaks tradition by bringing precise standalone 1080p projection to business owners and corporations at a price that’s within reach for any company.”
Pro8300 LED laser projector
In ViewSonic’s new hybrid laser andLED Full HD Pro9000 projector, the LED light and lasers combine to create a single light source, resulting in vibrant and rich display colour that the firm says far exceeds that of a normal mercury light projector.
In addition to being environmentally friendly, this mercury-free technology also delivers a longer operation life of over 20,000 hours. Coupled with dual HDMI ports and its lamp-free design, the Pro9000 is ideal for home cinema environments and Pro-AV installations. The Pro9000 is expected to be available in Q3 2012.
“Laser hybrid illumination technology has changed the way that projectors are able to manipulate light and images. This new model is lamp-free for an even lower total cost of ownership. As a result, users get a higher quality picture and ultra high contrast ratio, making projectors with this technology ideal for home entertainment, professional audio-video, corporate or education

RGB chipsets improve projector performance by up to 40%
Luminus says its latest nitride Big Chip LED is the world’s brightest
Luminus Devices has announced it has tripled the brightness of its semiconductor green LEDs over the last five years, and expects to at least double it again.
Green light is the major primary colour that contributes to white light generation in systems with Red-Green-Blue illumination, and the performance of Green LEDs is considered by the industry as the major limiting factor in replacing high pressure mercury lamps in projection displays.
Combined with its thermally-enhanced packaging technology, Luminus’ latest achievements in Pure Green LED output allow its projection-optimised RGB chipsets to achieve new performance levels in projection system categories covering portable,
