While this device may be too big to be called a smartphone, Paperfold stands out as a triple display mega handset with foldable screen panels. This is merely a project and a prototype right now, developed by researchers at Queen’s College in Canada.
The PaperFold uses 3 different screens that can fold over one another and are responsive to where they are in relation to each other. For example, if you fold out the device and make it look like a laptop, one of the screens will be a regular display and another one a keyboard. In PaperFold each of the screen tiles can act independently or like a part of a single system.
The product can shift to multiple form factors, offering support for mobile tasks that require large screens or keyboards on demand. Still, the core device remains reasonably slim for a prototype, but there’s a long way to go before this becomes anything more than a test. There’s a video of it below and I wonder if this is more or less advanced than what Samsung and LG have in their labs.
