"Most 3D systems are anaglyph or polarization 3D, both of which require glasses. Some of the new 3DTV sets use the Eclipse method, where a mechanical shutter blocks the light from each eye while the image appear on the screen. For that to work, the viewer needs to wear expensive electronic glasses, and the TV set needs a very high refresh rate, making the process so fast that viewers don’t notice the shutter."
"Now 3D is the big game for entertaining. One big market is computer games, and new complete 3D titles are coming to the market every day. Hardcore gamers are buying expensive 3DTV sets because of the refresh rates, which are much higher than traditional computer monitors.
Another market for glasses-less 3D is digital signage. Advertisers are looking for innovative ways to attract attention in malls, shopping centers, and stores. The big advantage of 3D in this market is that this new form of information transfer and awareness creation awakens more interest and makes a longer-lasting impression on the customer, but asking people to wear 3D glasses when they enter a store or a shopping mall is impossible.
3DFusion uses proprietary technology based on lenticular lens design. Screen gain and image brightness can be enhanced by directing the projected light in specific directions. Typically, commercial-quality optical lenticular lens array film material is produced via hot melt extrusion on to cylindrical engraved mandrels. This method is very cost-efficient and has the ability to produce large quantities of lenticular material. 3DFusion is fixing a sheet of lenticules on a LCD display. Since the lenticules are transparent, the full brightness and contrast is preserved. The advantage of this autostereoscopic approach is that the viewer can see the 3D image independently from the angle of view. Since the LCD under each lens is divided into subpixels, each eye sees different subpixels; this is especially important for video walls and large outdoor displays.
3DFusion has installed a fully operational 3D digital signage kiosk, the first of its kind in the US, at the Shops at Ithaca Mall. The company plans to expand the network to thousands of units all over the country, reaching an audience of several million people.
Currently, 3DFusion is offering 42 inch and 52 inch LCD displays with lenticular technology, along with a 132 inch video wall composed of nine 42 inch displays. All systems feature autosensing between 2D and 3D modes and plug-ins for most popular 3D rendering software, such as 3DX Max and Maya."
…"With 3D games, movies, and sporting events becoming more popular, the appeal of a glasses-free solution for 3D displays is clear. People are not comfortable using 3D glasses after the initial excitement of getting a 3D set. If autostereoscopic systems become mainstream, 3D could be in most living rooms in a few years."
