Flexible Displays – What are they and How do they work?.

Over the past year or so there has been a lot of excitement about the release of flexible displays. The mass production of flexible screens is greatly anticipated, in part because of their purported indestructible qualities – but mostly because they guarantee, bona fide, that we are living in the future we imagined as children. In this article, we take a look at flexible screens and displays and give an overview of how they work.

What is a flexible display?

If you haven’t worked it out already, flexible displays are displays which are fully bendable. Samsung announced their line of flexible screens in early 2012, branding them “YOUM” and snapping up other trademarks like FAMOLED (flexible active matrix organic light emitting diode). As Samsung is the world’s largest manufacturer of OLED displays, we expect them to be one of the major players in bringing flexible displays to the market. It’s a very exciting development in screen technology which has a huge number of advantages and extremely cool uses!

The biggest problem getting in the way of making screens flexible was glass. Glass doesn’t bend, it’s thick, heavy and breaks easily. Flexible displays rely largely on existing display technology, known as an OLED (organic light emitting diode) or AMOLED (active matrix light emitting diode) screen.

Traditional AMOLED screens use organic compounds which create their own light source when a current is passed through them. As the OLED pixels create their own light source, they don’t need a back light like LCD screen technology, but the circuitry to control the pixels is fused into glass. Flexible displays simply replace the layers of glass with layers of (flexible) plastic film, allowing for them to be bent and flexed without breaking anything.

Looking to “Corning”, the manufacturers of Gorilla Glass, we can see that a flexible protective glass coating for flexible displays isn’t completely out of the question. Their product Willow Glass will allow for the easy protection of flexible displays.

I think it will be the future for all types of visual displays, perhaps even car Dashboards or the table your are working from, the list goes on and on.
