smokescreen
High visibility display based on low visibility medium | |
A box with a transparent front is filled with a dark,
opaque liquid. Inside the box are
light-colored (and possibly fluorescent (i.e. Day-Glo)) flat
objects that can be moved toward
or
away from the front of the box by
actuators. These objects could be in the form of the
segments of a seven-segment
display
(hence the category) or a low-resolution matrix similar
to the flip-dot displays such as are
used on buses and signs. Actually, the bistable magnetic
actuators used in flip-dot displays
would be usable for this. Other suitable actuators could
be muscle wire, air bladders, wax
motors, etc.
An advantage over flip-dot/flip-segment is that it can do
grayscale.

P.S. I am shocked that this idea title was available. I was
just going to use the subtitle as the
title, but it seemed too long, so I came up with that.

I read this electroscopic display patent a while ago, and while I didn't understand it at the time, it inspired me to come up with this idea. [notexactly, May 13 2017]
