According to Sankei Biz, Sharp (already providing Nintendo with the 3D screen of the 3DS) will provide Nintendo with a free-form display for their next handheld (they mention the 3DS or a successor) or maybe their QoL device. It's all a rumour, but quite credible if Sankei Biz is to be believed.
From the looks of it, mass production for that type of screen (not made just for Nintendo, it's one of Sharp's own projects) was supposed to start in 2017, but Sharp managed to speed things up and production will actually start in 2016. Apparently, Nintendo are experimenting with some sort of donut-shapred display.
If that free-form display is for the next handheld, I doubt we're going to see it before late 2016/early 2017 at the earliest. Same for QoL. What's more, costs for such screen will probably be quite high, and we know Nintendo like their components cheap in order to maximise profits on hardware sales... So who knows what it's all about for now.
