NC State's new efficient pico projector raises hopes for smartphone cinema

A team at North Carolina State University has developed a new liquid crystal projector that could spell the end of bulky and noisy cinema gear. Conventional tech passes unpolarized light through a filter, but the process is so inefficient that nearly 50 percent of the energy is wasted just keeping things cool. Fortunately, the Wolfpack and ImagineOptix filter claims to be 90 percent efficient -- meaning that future projectors could be far sleeker. It's also a good sign for future smartphone pico projectors, although we're not sure how the owners of our local theater will feel when we start undercutting them with just a phone and a white wall.
