South Korea's Samsung Electronics has agreed to invest $15 million in MasterImage 3D, a company that has been at the forefront of developing 3D technology for movie theaters and now plans to develop a system that will allow users of smartphones, tablets, and PCs to view 3D videos without glasses. The company said that it is also working on developing "larger auto-stereoscopic displays" -- presumably meaning theater screens on which 3D images can be viewed without glasses. In a statement, MasterImage 3D CEO Younghoon Lee said, "Samsung's investment supports our strong belief that we've just begun to realize the impact 3D will have on consumers."
