How Do Foldable Smartphone Screens Work?
Foldable smartphone screens are a new and innovative technology that allows for an extended screen size without sacrificing the portability of a smaller phone. They allow for a larger screen than any traditional phone while folding up into a more compact form.
The idea of a foldable screen is hard to believe because smartphone screens are typically made of multiple layers of mostly inflexible glass. However, foldable screens are now possible because of a not-so-new technology, often referred to as Flexible Display technology, built around Organic Light Emitting Diode (OLED) screens.
OLED screens are made of organic materials that emit light when electricity is passed through them. They do not require backlights to function, and as a result, can be made thin enough to the point where they become flexible, forming the basis of flexible screens.
Flexible OLED displays have been around for a while. Older flagship phones like the iPhone X and the Samsung Galaxy Edge series have flexible displays, but the technology was only used to give the devices curved edges. Now, flexible display technology has improved beyond allowing screens have just curved edges into making screens that can actually be folded.
