(Immediately checks for author affiliation to eInk or some bullshit mid-tier American university with an "up and coming" tech transfer office) Awesome, maybe this will actually come to market with a reasonable license fee!
Good news we can make much better color e-paper! Bad news, your epaper is made out of platinum and gold.<p>Looking through the paper it looks like an excellent advancement in terms of multi-color reflective paper displays. My hope is that the authors can continue the work to perhaps uncover some more economical mirror substrates and node combinations that give good results while not being precious metals.
> based on tungsten trioxide, gold, and a thin platinum mirror<p>Gold is currently 58 USD/gram, platinum 36 USD/gram. How much would be needed for a display?
At one point, maybe 10 or 12 years ago, there was lots of buzz about electrowetting displays that were meant to able to display video. I think that Phillips were working on it. Then I never heard of them again.<p>On the other hand, it's possible to buy oled televisions now so sometimes new technologies do make it to market.<p>This one sounds interesting although using both gold and platinum sounds expensive.
I know there is a do not editorialize rule but the original submission title “Nanostructure design enables new possibilities for e-paper in color” was a lot clearer.
