While exhibitors at last week’s 3-D Biz Expo in Los Angeles gladly showed off a couple dozen 3-D displays with images ranging from sunsets to roller-coasters appearing to jump out of the screens, they also included something they were less than proud to tout: those funny-looking glasses.
Companies provided either inconspicuous-looking black-rimmed glasses or bright orange shades to enable potential customers to get a true view of three-dimensional content instead of the blurry screen perceived by the naked eye.
For a look to the future, visitors were introduced to Royal Philips’ autostereoscopic displays, which are now only available for business-to-business purposes. The 42-inch versions of such displays allow viewers to see 3-D images without wearing glasses by providing as many as nine views from slightly different angles and combining them into a single 3-D image on-screen, according to Jeroen Brouwer, marketing and business development director at Philips.
For the time being, though, companies such as Samsung and Panasonic are selling 3-D-capable TVs that come with so-called active shutter glasses. Those devices are battery powered and synch up to software in order to control each eye’s lighting by moving around liquid crystals in the lenses. Such glasses cost about $100, compared with a few dollars for the more traditional “passive” blue/red variety.
What all of the companies have in common, however, is the intention of eventually ditching the glasses.
“The holy grail is eventually to have no glasses-based 3-D in the home,” said Chris Chinnock, president of consultant Insight Media. “You could start to see the first no-glasses 3-D TVs in three years.”
