The USPTO has just published a patent Microsoft applied for last year in which they describe a device with a main display and a secondary display which wraps around the edges of the device, which could be a smartphone or tablet, and which displays additional information.
Microsoft notes the secondary display could be used to display the battery charge level, the current function of the device (e.g., in a phone call, etc.), and more.
Would our readers be interested in such a handset? Let us know below.
