While companies try to figure out ways to pack in more pixels
per inch, as well as deliver resolutions that make crystal clear
images, there is still a strong push on the other side of the
spectrum: offer up color and video, all with a low power
consumption equivalent to e-ink. A group of researchers at the
University of Cincinnati have unveiled a project seven years in
the making, announcing the creation of a new electrofluidics
display. According to the researchers, the new display puts
reflective electrodes between a pair of layers of liquid, and
then they let ambient light do the rest of the work for them.
The researchers outline their method and creation in their
announcement, saying that right behind the display are two
layers of liquid: a pigment dispersion fluid kind of like an
inkjet fluid, and oil. And then between the two layers is a
layer of reflective electrodes. “Think of these electrodes as a
highly reflective mirror.” When ambient light passes through the
display and hits the fluids, and then
