From the article, the sizes they're talking about are 10 um pixels, or 10 um pitch, so approximately 2540 ppi. [1] Pretty respectable by modern standards, as Wikipedia says a lot of phones are ~600 ppi. [2] The demo was 3 mm pixels, so not quite as impressive.
Not sure what the refresh or contrast are, as the summary was really light on actual meaningful numbers. If somebody has the paper from something other than a paywall, maybe it has more.
The shape changing part might be neat, depending on how much shape changing there is, and how difficult it is to achieve. Maybe piezo style pixels or something.

- jajko 3y agoI am struggling to imagine where to use such a massive resolution, well beyond the best human eyes. As a photographer I can see some use in electronic viewfinders maybe, but in general pro / semipro photography is in long term decline, way too many enthusiasts (including me) ditched their heavy full frames for mere top phones and never looked back (for me its general shift into parenthood and lack of time for all that annoying processing too, I perform all I ever needed in phone in few taps and for more detailed work Samsung's built in pen is above great).

- araes 3y agoWhat you're describing is what most of the camera manufacturers are dealing with. There's not really "that" much to sell to people any longer, because you can get a "good enough" camera that will fit on a quarter. Nikon for example, just bought Red One because (in my opinion) there's not much left in the consumer handheld market for DLSRs fighting with cell phones. [1] At least with the current development trajectory on both fronts. In terms of what might matter, other than prior comments VR suggestion, TVs. People always gonna want their 2x TV. Same as the Bill Gates argument from 20 years ago. What are people gonna do with all that storage? Make larger videos. (likely porn).

- thfuran 3y ago>People always gonna want their 2x TV. I think 8k is pretty much the limit for plausible consumer screen size and viewing distance. Few people are going to want a tv large enough that a higher resolution is useful.
- itishappy 3y agoI believe that's the size of the individual particles, not the expected pixel size. The particles will still need to self-assemble which (I suspect) requires larger numbers of particles. An analogy might be quantum dots, which are nano-scale structures, but each micro-scale pixel uses many dots.
