Plastic Logic flexible AMOLED

The screens are still in the early stages of development but are already capable of 30 frames per second refresh rates, 256 levels of grey and improved brightness. E Ink should be worried. And if Plastic Logic cracks colour, as it claims it's close to doing, all other screens are in danger too.

But until there are actual products for sale, it's still irrelevant.

If it is an AMOLED screen, then why is it a challenger for e-ink which exists precisely because of the need for a non-light-emitting screen?

Exactly. AMOLED are less power hungry than LCDs, but they inherently consume power all the time when displaying an image. No challenge to E-Ink for battery life either.

I'm still hoping that Amazon's Liquavista display prove suitable for ereaders. Very low power, high contrast, fast refresh, wide viewing angle.

But again, until actual products appear, it's hard to tell. I had high hopes for Mirasol, but until they lick the viewing angle problem, it's not really viable.

That's what I've always believed, since LC displays are a filter in front of a back light.

But here is a credible report that claims that the best LCDs are both brighter and more power efficient than current (2012ish) AMOLEDs.

I was wondering the same thing. As several comments on the linked article said, it seems the author is unaware of what an e-ink display's benefits are.

Without reading your link, I believe AMOLED's power advantage manifests when the displayed content is mostly black, as it is in that article's wrist band pic.

More vaporware from PlasticLogic?

That's correct, LCDs have a power consumption curve that is basically flat, whereas on the AMOLED displays the consumption increases with the "whiteness" of the screen.

Well, to the extent that IEC 62087 represents typical conditions, OLEDs already outperform even LCDs with local dimming, and local dimming is not that common yet.

They might be speaking from the point of view of people who don't really care whether the screen emits light or not, just that it can wrap around your wrist.

But how is that a challenger for e-ink? As a number of people have elaborated, the purpose of e-ink is for things like ereaders that last for weeks on a single charge. E-ink is not a company that makes flexible wristband displays (and shame on them for wasting time on this pointless endeavor) it is a company that makes low-power displays. Until AMOLED can replicate that, e-ink is not threatened in what they actually do...

Although eInk is better suited to books (plain text), more and more people are actually switching to tablets so yes, they are actually threatened. eInk is become more and more a niche product.

They are not threatened by this new AMOLED screen.

Yes I am well aware that the low-power e-ink-display ereader is threatened by simple lack of interest. That is a separate issue, which is held by today's tablets, not new displays that are being hyped up for all the wrong reasons.

We shall see, but it does not look like eInk will feature prominently in the upcoming wearable onslaught.
