Abstract
Electronic paper, or e-Paper, for use in displays has seen rapid
growth in the past decade because of its potential as an alternative
to traditional transmissive displays. Offering several critical advantages
over current display technologies, including high contrast in direct
sunlight, wide viewing angles, and compatibility with flexible substrate
processing, electrowetting displays (EWDs) have made it to the forefront
of e-Paper research and development efforts. Here, we describe a new
design for the fabrication of multi-color, bistable electrowetting
displays. Using a laser-based process to pattern an in-plane electrode
design, liquid can be manipulated out-of-plane. This process relies
on electromechanical pressure forcing water in and out of channels,
causing colored oil to be displaced. When voltage is removed, the
oil remains in its current position, resulting in bistability. We
have demonstrated multi-color, bistable pixels that maintain their
state at
${\rm V}=
0$
for several days, which drastically reduces the
power required to drive the display.
