New Samsung patent for flexible display structure shows flex OLED's inner workings
Samsung Display was granted a patent for a new flexible display structure by the USPTO. The design and technology shown and explained by the patent will allow for bendable displays and foldable smartphones, as well as screens that don't shatter upon impact. This is probably the technology which will go into Samsung's future bendable or foldable devices.

The invention consists of a first electrode layer, dielectric elastomer film, and a second electrode disposed on the upper or lower portion of the flexible display panel. A voltage is applied to the both electrodes, forming the first and second electrode layers. This way, the flexible display bends without pressure applied by the user's hands.

The flexible display panel includes a flexible substrate, made of a plastic material with excellent heat resistance and durability properties. The possibilities include polyethylene naphthalate (PEN), polycarbonate (PC), polyarylate (PAR), polyether imide (PEI), polyether sulfone (PES), and polyimide (PI).

Recently, Apple was granted a patent for a smartphone design with a flexible display. When the phone is not in use, the screen folds up like a clamshell device using a hinge that connects both halves. The hinge is designed to allow for a front-to front or back-to-back configuration. This is one of the many ways in which Samsung's invention could be implemented in future smartphones, tablets, and wearables.

Wow, not the USPTO is making sense - giving a patent to a 1st party manufacturer, as opossed to the patent they awarded to Apple concerning flexble display folding like a clamshell. Apple isn't a 1st part manufacturer of the displays, Apple buys displays from 3rd parties. Display patents should only be awarded to 1st party OEMs, which means the OEM which designs, creates and manufactures the final product!

They should also have an expiration date (only in case the manufacturer doesn't deliver)! That way ... all patent trolls would be gone in a few years!

I'll never understand the US patent system...it's one thing having a concept but why should another company be allowed to patent somehting remotely similar? At least with Samsung they've actually showcased some of these panels to show they really are working on it. WHat have we seen from Apple regarding display production whatsoever?

Apple doesn't produce any of its parts but has others doing it, yet getting patents, yeah I entirely agree it is a very odd thing, they claim to design the stuff and have others build it as with their processor and such, but even then its based off other things others have made.

You have to wonder how durable these flexible displays will be, I mean there's many flexible things, but flex them enough and they break.
