Breakthrough in nanostructure technology for real-time color display
- m3kw9 3y agoColor e-ink
- qwerty456127 3y agoGreat! I personally would better like a breakthrough in their pricing though :-) The very reason I would like an a eink display is its lofi-ness, lack of real-time visual effect bells&wistles. To calm down and work with my emails, spreadsheets and mind maps like if I were reading and typing on plain paper. So I don't really need "real time". I would buy a huge one (like 49-inch 4K to fit a lot on one screen) but even an ordinary size costs much, let alone so big :-(

- orbital-decay 3y agoThat's not EPD though, that's more like IMOD/Mirasol back in the day. It manipulates color by restructuring so it will always have the same limitations as MEMS displays like IMOD. The picture in the article gives an impression on poor viewing angles on this thing.
- i_am_a_squirrel 3y agoI hate to break it to these people, but we've had real time color displays for a while now :D
- Tuna-Fish 3y agoReal-time color emissive displays. This work is about reflective displays. (e-ink)
- fnordpiglet 3y agoCan’t quantum dots not be used in reflective displays as well?
- fngjdflmdflg 3y agoHow do you update the dots when the image changes?

- araes 3y agoFrom 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).
- thfuran 3y agoVR headsets want emissive displays but can make use of extremely high dpi on the display element itself.
- 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).

- pmontra 3y ago"the size and color of micro-nanostructures adapt to fluctuations in alcohol concentration or pH value" Varying them quickly enough is the remaining part of the problem.
- Turing_Machine 3y agoHmm... at that small of a scale, I'll bet you could change the localized pH near an electrode pretty fast with a reversible electrolysis reaction, given the proper choice of electrolyte(s).

- UberFly 3y agoWe're finally inching closer to that color-changing finger nail polish from Total Recall.
- mpalmer 3y agoNot to mention the singing cereal boxes of Minority Report.
- ClassyJacket 3y agoThat was The Fifth Element!
- Loughla 3y agoNo, it was total recall. The Fifth Element had a box thing that painted the secretary's nails. Not necessarily the same thing, could just be a little nail robot inside it. Total recall had the tap to change color feature.

- LarsDu88 3y agoI remember reading about the Lycurgus cup (https://en.wikipedia.org/wiki/Lycurgus_Cup https://en.wikipedia.org/wiki/Lycurgus_Cup) years ago in college. Pretty cool we can now control the phenomena. Highly, highly doubt this will result in a commercial competitor to OLED one day, but who knows? Perhaps there will be a path here towards translucent displays...
