The Rise of OLED
So, why are we seeing so much talk about foldable phones now? One of the biggest reasons is the OLED screen. If you remember your OLED tech, you’ll know that OLED screens combine color and lighting panels into one versatile substrate. That means that they can be flexible in ways that LCD screens simply can’t be. You will find that all these foldable prototypes are using OLED technology or similar screen technologies to enable their flexible design. This is also one of the reasons that costs are so high. OLED screens in these sizes aren’t cheap to make.
It also raises questions about a foldable iPad: Would Apple make it fully OLED? It’s possible: Apple is shifting its OLED contracts in preparation to create larger screens, which could make the chance of a foldable iPad more likely.
