All energy savings have value. You may argue relative significance, but a joule saved is a joule saved.

Agreed on that, but it's hard to justify the "revolutionary" tag if the end-product only increases its battery life by 10 or 20%.

Combine this with 10 or 20% savings in CPU energy, 10 or 20% savings in radio power, 10 or 20% in RAM energy for example, and you start getting into revolutionary use cases. We're now looking seriously at embedded small devices that can sit in one place, take up the space of a pack of cards, and transmit useful data over the course of 20 years. Now we start getting into revolutionary because this opens up applications like building moisture detectors into roof construction, embedding a screen into the back side of your front door that shows a log of when it was opened or closed, or maybe something surprising like color changing shoes.

I wonder how much this would increase the battery life of an Apple Watch?

Dream on, they’ll make it thinner

That's actually my number gripe about the Apple Watch, it's a bit too thick, and I don't have a problem with its battery life.

I'm totally fine with Apple prioritize form over function when it comes to wearable, after all, I don't buy mechanical watches for their "functions".

There was a time where I’d get super hyped when reading these kinds of promises. Transparent displays, foldable screens. Truth is, we’ve been seeing working prototypes at events like CES for more than 15 years. I’ve come to realize the mechanics of these companies are similar to the car industry. New technologies are presented for the same reason car companies present strange concept cars: PR

The weird thing is that we already have “foldable screens.” But all the phone makers have done with them is to give us slightly less bezel on our glass rectangles.

I’m wondering if this is a “flying car” thing—if actually handing consumers ultra-thin bendable (but not actually creasable) panels would be a dumb idea, because consumers would try to exceed their tolerances and break them too easily.

(This is also, I think, why we don’t see more optical cabling standards outside of the enterprise space. The average consumer can’t be trusted to install a glass-fibre cable run without breaking it; and when they break it, they’ll get angry, because glass-fibre cables still cost a lot of money. And plastic-fibre cabling, though more tolerant, is far less of an improvement over copper, especially in attenuation distance.)

From a bit of googling just now, it seems that LEDs are effectively “two-way” devices: they emit light, but they can also sense light—just like the way that any loudspeaker is also fundamentally a microphone.

Which leads me to wonder: would a microLED array make a better camera input than current CCDs?

The revolution is in the amount of time the display can be on, and the amount of data it can display 24/7. That is currently the big knock on most smartwatches - you have to move your wrist to activate the display and see the time. If that barrier is removed, it is revolutionary.

The displays on Garmin smartwatches are always on. However they're reflective displays so you have to activate the backlight to see them in the dark.

And the battery lasts for a week or more.

Source: last charged my watch (3HR) more than a week ago; 47% remaining.

I’m guessing that “photo” is in fact a mock-up? Because it appears to show a screen that is able to occlude the background with both light and dark colors, which is not consistent with the description of the technology.

If it turns out its a mockup, that would be very sad. I feel slightly misled.
