Sharp demonstrated a new display prototype called the Corner-R, which uses the company's Free-Form IGZO LCD panel to create a display with curved corners.
From the photo above, it seems like the display is also curved around the edges like Samsung's Edge-type OLEDs, but it may be just a curved glass, I am not sure. This is just a prototype demonstration, though, it's not clear whether Sharp intents to commercialize this display.
Sharp recently announced that it will invest $570 million in its OLED business - and will establish pilot lines at its plants in Osaka and in the Mie Prefecture. The pilot lines will begin OLED production in the summer of 2018. This follows Foxconn's $3.5 billion Sharp Takeover and Foxconn's aims to invest a total of $1.8 billion in OLED technologies, as it wants to become an OLED supplier to Apple.
