LAS VEGAS — Consumers may soon be able to toss those pricey 3D glasses aside. Or just not buy them in the first place to watch their 3D TVs at home.Samsung, which leads in 3D TV sales, is pairing up with RealD to incorporate the Los Angeles-based company’s projection technology found in theaters for 3D screenings into its new TVs to eliminate the need to wear current pairs of pricey 3D spectacles that require battery power. New display technology would essentially let viewers wear the same 3D glasses at home that they wear at the megaplex. Most of the 3D glasses sold for the home today have active-shutter lenses, which provide better visuals than the pairs of black glasses handed out in theaters or the traditional cardboard pair of red and green lenses consumers are used to. And for that, they sell for around $150 or more, which has turned off some consumers. By working with Samsung, active shutter technology will be built into Samsung’s new 3D TV sets. The new technology will be called RDZ and be compatible with RealD’s glasses currently worn by moviegoers. Move should make the TVs more attractive to buyers, especially for families who won’t need to buy multiple pairs of glasses. Last year, 3D TVs made up less than 5% of HDTV sales, with some industry watchers putting that figure closer to 2%. Samsung is also trying to make its current line of glasses a little more attractive, as well, by pairing up with Silhouette to make the industry’s lightest 3D glasses, that weigh just 1 ounce. The glasses switch on when 3D images are being viewed and can recharge wirelessly. Samsung declined to disclose when its new 3D TVs would reach retailers.
