Researchers at Samsung Advanced Institute of Technology , South Korea, have built a prototype of a seamless foldable display that opens up to look like that of a regular smartphone .
The display consists of two active matrix organic light-emitting-diode (AMOLED) panels covered by a silicone window that prevents scratches and can serve as a touchscreen.
When folded down, they are separated by a gap of just one millimetre. But when the screen is opened, one panel lies almost completely on top of the other and appears seamless.
The researchers tested the foldable display's durability by performing 100,000 folding-unfolding cycles. They said the key to success was controlling the optical properties of the materials.
This new type of technology has not so far taken off because of the high manufacturing costs.
