SAN FRANCISCO: 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.
