Flexible Screen
A flexible screen is one of the latest inventions that will help create bendable phones.
A flexible screen allows a phone to stretch and also bend, making it more durable and also allows for new input methods.
For example, you could choose to flex the phone backwards or forwards to zoom in or out, to increase or reduce text size, picture and so forth.
The greatest merit with this technology is that it gives you a greater screen to phone size ratio.
A drawback with current phones is that if you want a bigger screen display, you need to have a bigger phone and the bigger the phone - the less convenient it is to carry.
But with flexible screen technology, mobile phones with large screen displays can be bent, folded or rolled-up into a compact size to fit in anywhere
The screen is made from a type of hydrogel - a material similar to that used to make soft contact lenses.
What is unique about this latest invention is that electrically charged molecules flowing through the hydrogel forms an electric field beyond the flexible screen. When fingers approach the display, it can detect and distinguish them from a stretch or bend in the screen.
The hydrogel flexible screen is then connected to an electronic operating system and embedded into thin silicone rubber to create a bendable phone or tablet.
The hydrogel flexible screen is not soft or weak like how most people think of gels, but very tough can stretch 20 times its size and is inexpensive to manufacture.
