A recent patent application filed with Google Galaxy Fold. Patently Mobile describes a method for constructing an OLED panel that can be used in a "modern computing device."
What does this mean? Google does not produce Any displays of its own, and is not the manufacturer of its own handsets. Like Apple with its iPhones, Google reportedly outsourced manufacturing of the Pixel 3 to Foxconn, and both HTC and LG's shared manufacturing duties on the Pixel 2 phones. That does not mean it's impossible for a product based on the light of day, it's probably because it's a good thing screen itself.
The patent goes on to imagine a possible folding device that could bend in two different places – a "Z-fold display" – without breakage, thanks to what sounds like the screen of the device , We're not showing manufacturing experts, though.
It's not clear whether Google would ever build a thing or why we'd want a Z-fold, but the survivability of folding phones is definitely silent on open question. Gorilla Glass manufacturer Corning is developing a glass screen that can be folded, it hopes to be more durable than existing plastic solutions.
It's important to mention that Google's patent does not even mention the word "phone" once. Instead of using modern computing devices, Google is still working on tablets and laptops anymore
Google's interest in foldable smartphones has so focused on the software aspect of their design. Android would work as the Galaxy Fold's operating system. Clearly, the future of Android, and Google appears to be interested in both the hardware as well as the software.
