A group of researchers at MIT have developed a proof of concept transparent display that portends a future of clear displays that are inexpensive to make and easy to acquire.
The team said that some of the limitations of current transparent technologies include the inability to see projected images from more than one specific angle as well as the complexity and expense of glass equipped with built-in electronics.
