Answers to questions raised in the ITWire article 'Doubts about the Laser TV', including 'was the plasma TV set up correctly' and more. These answers and commentary were written by Larry Marshall, the co-chairman of Arasor and one of the developers. Just to repeat, we’ve edited them grammatically and made minor changes for clarity, but otherwise these are Larry’s answers and comments:

Besides, the Laser TV was by no means a finished product, so there are still huge improvements that can be made - something which will be showcased by Mitsubishi at the CES 2007 in Las Vegas. The prototype showed in Sydney is basically a DLP TV with the laser technology replacing the light bulb - only minor tweaks had been done to account for the wider spectrum of the laser. In contrast, the plasma is a commerical product that has been selling for years, and I trust they are well & trully tweaked. Again, the plasma looked great, until you saw twice the colour coming from the Laser TV next to it. The Laser TV is brighter – there’s no fundamental limit to screen size like there is with plasma or LCD - the screen is just a piece of glass rather than a complex, multilayer structure than suffers of imperfections when you exceed about 40" diagonal screen size in a plasma or LCD. There is simply much more light from a laser, so you could turn up the plasma all you like and it will still not be as bright. I think the people who haven't seen the Laser TV are missing the point. If you were at the launch most of these questions were asked & answered. The laser doesn't make the TV any higher resolution, it’s main benefit are that it delivers twice as much colour as a plasma or LCD TV. The Laser TV gives you almost the full color spectrum that you see in real life, and the contrast in things like fleshtones, deep blues & reds, and also rich yellows really jump out at you because you've never seen them before on a TV. That's why it looks better and brighter than plasma or LCD. It’s twice the colour that gives the real life rich content experience. The DLP or rear projection TVs are big and clunky because the optoelectronics engine that drives them is made of discrete components including a huge high power lamp. The optical chips (used in Laser TV) simply integrate all those separate components together into a chip, and that takes out the manual labor, cost and bulk. Arasor make optical chips that enable the colours to be produced for the TV, Novalux makes infrared lasers that drive the chips, and neither of us make TVs. We just supply the chips. Seiko, Epson, Mitsubishi, Unaxis, and others make the TVs or the guts of them. You should think of us like Intel or AMD making the heart of your Laptop, but it’s Dell that is the laptop maker. In fairness, Novalux are the pioneers of Laser TV and have succeeded where many others have failed. We've all been in the industry for almost 20 years, and have seen many attempts to use lasers in display. Jean-Michel Pelaprat (of Novalux, and presenter at the Laser TV launch) is a veteran of the laser industry, he and his team at Novalux have done an outstanding job of solving these problems. Arasor is like the Intel of the optoelectronics industry creating a silicon chip that integrates optoelectronics and wireless solutions for a number of applications including:
