Samsung Electronics Co Ltd said it will introduce a smartphone with a curved display next month.
Curved displays are an early stage in screen evolution that is shifting to bendable or foldable designs, eventually allowing mobile and wearable gadgets to take on new forms that could radically change the high-end smartphone market.
In January, Samsung, which has taken over from Apple Inc as the global smartphone leader, showed off prototype products with a flexible screen and a display that extends from the side of a device.
But technology firms have yet to figure out how to mass produce the parts cheaply and come up with display panels that can be as thin as a sheet and highly heat resistant.
Curved display is already commercially available in large-screen televisions.
Samsung and its home rival LG Electronics Inc started selling curved OLED TV sets this year priced at about €6,700.
