The United States Patent and Trademark Office recently published details on an interesting Microsoft patent. The patent relates to a two-sided smart device display system for phones and tablets. It features an integrated second low-power, possibly E Ink, display on the back that would show certain types of information.
The secondary display could come in very handy for getting things like a clock off of the main display to free up space. It could display other information that might otherwise not be shown. The second display would use its own low-powered processor, which would reduce the power load from the primary display.
This could be very handy and can be used in many ways. Hopefully we will see this implemented in our phones one day soon.
