Laser TV

At the CES next month in Las Vegas, Mitsubishi will be unveiling its long-awaited and long-promised laser-powered projection TV. If all goes according to plan, we could be seeing the first commercial versions of Laser TVs hitting the market within the next few months.

The incorporation of laser technology in televisions is particularly exciting on many fronts. Laser TV promises to bring the brightest, sharpest and most colorful picture the HDTV market has ever seen. The secret lies in the use of a compact trio of colored lasers, replacing the traditional light lamp. Lasers are inherently stable, very bright and energy efficient, also making these models “green” and environmentally friendly, requiring less energy to operate than a plasma or traditional lamp-based television. As an added bonus, Laser TVs also weigh less than plasma sets, will cost less to manufacture and have a very long-life package.

Until recently, solid state lasers have been too expensive to develop for mass production in televisions. Novalux has developed an inexpensive and tiny laser dubbed NECSEL (Novalux Extended Cavity Surface Emitting Laser) for use in microdisplay-based devices, including home theater front projectors and rear-projection TVs. As more manufacturers and consumers realize the potential of laser light sources, 2008 could be the dawn of a new age in HDTV and display technology centered on laser applications.
