How does a phone fold, why does its screen not break

The advent of touchscreen foldable phones is no less than a revolution in the world of mobile phones. Foldable phones have been in vogue for many years, but their entire display was not made of glass. Now a phone that looks like a single screen folds from the middle. This question must have come to your mind at some point or the other that how does this happen.

Actually, the screen in most foldable phones is not LCD but OLED. The image you see on the phone is made by millions of color specs. There are different ways to get images from these specs. These methods are called LCD, OLED, Micro LED or Mini LED.

Not glass, but plastic
The material on which millions of color specs are placed is called substrate. For many years this substrate has been made from glass. As you know, glass cannot bend too much. The use of plastic display instead of it made foldable phones possible. But scientists did not do only this. Apart from this, he also found solutions to many problems. For example, he also made arrangements to ensure that the display does not get damaged if the phone is opened and closed repeatedly for a long time.
