Samsung readies first batch of super-thin AMOLED displays

(Phys.org) -- Samsung is set to begin manufacturing its "Youm" displays which have been generating pre-launch excitement as ultra-thin AMOLED panels that will be bendable, stretchable, rollable and foldable like a piece of paper. Samsung expects to begin production of its 0.6mm Youm displays this quarter, with a goal of seeing the first products with the technology to market by the end of the year. Oddly, though, the displays to roll out this year in the first batch will not have a flexible substrate. They will have a protective glass layer, which in turn will make them unable to take other forms or shapes, the very bend-it, fold-it feature that draws interest at industry shows.

According to those close to developments at Samsung, the real deal AMOLED displays with will appear in 2014. The early batch at the least will carry the AMOLED features of being very thin, with one third the thickness of current mobile screens.

are thinner, more efficient and offer better picture quality than LCD or plasma displays; OLED is a flat light emitting technology made by placing a series of between two . OLEDs also can be made to be flexible and transparent. The term AMOLED stands for Active-Matrix Organic , an advanced display technology that is still considered in an . Asia has become the hub of AMOLED display manufacturing activity, with , Taiwan and China the key players. The United States represents the single largest market for AMOLED displays.

According to reports, Samsung’s earliest models, of the inflexible kind, will be covered with a layer of glass that is 0.4mm thick. The panels, compared to current generation panels, will be a thinner 0.6mm — in contrast to the current measurement of 1.8mm thick , but with rigid protective glass on top. Observers say that by manufacturing these screens now, Samsung gains experience in producing them for traditional, rigid devices such as phones and tablets. When OEMs will start thinking about flexible gadgets, Samsung intends to be ready with ample supply.

The company has an internal goal to mass-produce truly flexible displays by 2014. Samsung is confident of a coming upswing in demand. Samsung predicts that by 2014, 50 percent of cell phones may carry AMOLED displays and by 2015 it could be the main TV panel technology.

Latest developments suggest Samsung strategy regarding the displays are on course. In its quarterly earnings call in October last year, Samsung’s vice president of investor relations, Robert Yi, told an audience of investors and analysts that flexible displays would be introduced in 2012 and that the application “probably will start from the handset side.”

A bendable display is less likely to break when the glass breaks... My guess.

Economies of scale, if the new display can displace others yet be compatible with more form factors...

Many reasons:

1) A bendable display is only part of a gadget. It may take a lot of design work to settle on a usable form factor where a flexible display is attached to the non-flexible electronics that drive it and other stuff (such as cameras, wireless data and/or voice, RAM, CPU, etc.) How they will do this will be interesting to see.

2) This is a new display technology. By using it in rigid devices they can first work out one set of problems (stable display chemistry over a long device life, etc.) while giving themselves more time to work on flexibility issues, with less risk of shipping a lemon product.

3) As the article pointed out, it is a way to build manufacturing capacity up before launching a device that is likely to have huge demand.

whats the point in making unbendable bendable displays

Think of displays on a ball surface, or a convex/concave surface where appropriate. E.g. something that fits the concave surface of your hand, or a 'crystal ball' like object, or a display that covers the strut of your car giving you information or visbility without the need to have an akward flat plane installed, or ...

There are a lot of possibilities for surface adaptive displays that only need to bend once - during installation.

The game changer would be a smartphone with a tablet sized screen (7" or so) that could be folded to fit in your pocket when not in use.

Displays can be made in any shape. As amoled allows for transparency too the possibilities are huge. You could have a transparent layer of this on the inner side of your cars windshield (not necessarily covering the entire surface) rendering the panel useless, put external cameras (maybe IR) and you no longer need mirrors while getting better vision at night, integrate a GPS with it and you get AR assisted driving without taking your eyes off the road, give it the capabilities of a smartphone or a dock where you fit your smartphone so it can control the display and think of what you could do with it.

Samsung does not provide Apple with AMOLED screens, only their LCD screens. Their galaxy line of phones and tablets all use AMOLED screens, an area in which Samsung has significant advantages over other manufacturers. This article from Wired covers the confusing display market very well. If you actually care about the topic, it is a great read.
