alt Hacker NewsI don't understand these statements:
"...smart displays and vibrant art pieces (that won’t fade over time)... However, when the display is turned off, the images become visible, which allows for information display without using any energy."
Nowhere does it say that the coloration can be changed, once applied. The different-sized particles are embedded in acrylic. So how does this enable a "smart display?" I guess you can say that a turned-off monitor can now show "information," but that information printed on the screen would be static for all time... wouldn't it?
Presumably they're making the leap that this printing technology can be leveraged to develop an alternative display technology that would change the structure in real time, kind of like color e-ink displays.
It's quite the leap, but that's science communication for you!
