Two years ago laser TV appeared in the marketplace to compete with LCD and plasma screens, as described here:
Now there are two new companies entering the field with innovative laser technology.
The first is HDi, which has introduced a 100-inch 3D laser screen with a refresh rate of over 1,000 hz:
According to their press release, the advantage of the fast refresh rate is the elimination of headaches when watching 3D material:
HDI Ltd. has completely eliminated the adverse effects, such as migraines, dizziness, nausea, and motion sickness, long associated with inferior and expensive shutter glasses and substandard 3D technology. HDI Ltd. delivers the most immersive, comfortable, and natural 3D viewing experience in the world with low-cost and light-weight proprietary polarized glasses. Technology journalist Richard Hart called HDI Ltd.’s picture quality, “the smoothest yet, and smoothness means no headaches,” and Steve Wozniak, co-founder of Apple Computers, stated, “Without a doubt, the best demonstration of 3D technology I have ever seen.”
The technology is also innovative because there are no battery-operated shutter glasses. Instead, you wear polarized lenses as you do in movie theaters. This diagram explains the process:

The second is Prysm, which is using lasers to drive a phosphor coated screen. This lets the screen have the advantages of a CRT or Plasma display (bright phosphors emitting light right on the screen surface) without the weight or power consumption. Laser light is exciting the phosphor rather than electron beams or high voltage. The technology is described here:
In theory this technology could create very large displays at relatively low cost:
With its advanced design, the LPD display system presents a breakthrough in low power consumption. LPD can consume relatively little power while still showing a bright and vivid image from any angle. The freeform scalable freedom achieved is unmatched by any other display technology. The design of the Laser Engine has total flexibility without constraint in order to bring to market displays of any size, shape, curvature, brightness and resolution.
The solid-state components and technologies used in the LPD design are proven reliable and the system self monitors to ensure many years of operating life. Finally, all materials used are environmentally safe, require little energy and safe materials to manufacture and are easily recycled. Together, these advantages offer low cost of ownership and high performance for many display applications.
