Foldable screens, rolling displays: what will our future smartphones look like?

The first idea is a prototype of a smartphone with a tri-fold screen, i.e., with a double folding system, both inwards and outwards. — AFP Relaxnews

At SID Display Week 2022, the world's largest conference dedicated to displays, held in San Jose, California last week, the two South Korean tech giants Samsung and LG caused a stir with their presentation of revolutionary foldable screens that could, in the coming years, be used on new high-end smartphones.

Last year, Samsung generated headlines with the release of the Galaxy Z Fold3 and Flip3. While sales figures have not yet been made public, Samsung has revealed that it increased its sales of folding smartphones fourfold between 2020 and 2021. However, their prices, above a thousand US dollars, still make them a niche market.
