It described its Infinity Flex Display as “the foundation of the smartphone of tomorrow” and said it intended to start production within months.
When unfolded, the device resembles a 7.3in (18.5cm) tablet. When closed, a separate smaller “cover display” on the handset's other side comes into use.
Smartphone makers bet on foldable screens as next big thing
For the past few years, the smartphone industry has been searching for a breakthrough to revive a market mired in an innovation lull and a sales slump. A potential catalyst is on the horizon in the form of flexible screens that can be folded in half without breaking.
Samsung and several rivals are preparing to roll out such screens to make devices more versatile for work and pleasure. The foldable screens could increase display space to the size of a mini-tablet, but fold like a wallet so they revert to the size of regular phones. But there are questions about price and durability.
