Dolby Laboratories Inc. 3-D glasses are arranged for a photo at the company's offices in San Francisco, U.S., on Friday, March 12, 2010. U.S. theaters are using equipment made by both Dolby and RealD to show Walt Disney Co.'s 3-D movie "Alice in Wonderland." While RealD accounts for more than 2,000 screens, Dolby is counting on the movie to spotlight its technology, which it says provides for better visuals without the need for special screens.
