Microsoft files patent for two-sided smartphone display

While we have seen our share of smartphone designs, nearly all of of them have one big touch screen on the front. But what if a smartphone could have two different displays on one case? Microsoft has apparently filed a patent that would create such a product. PatentBolt.com has posted up some images and details from the company's filing with the US Patent and Trademark Office. 

The design would have a regular high-powered touch screen on the front of the smartphone, along with a low-powered screen on the back of the case. The rear screen could be used to display a variety of information. For example, it could become an eInk screen for people to read texts more clearly than on the front screen of a smartphone.
