E Ink announces a full color electrophoretic ePaper display

SAN FRANCISCO–(BUSINESS WIRE)–E
Ink® Holdings
, “E Ink” (8069.TWO), the leading innovator
of electronic ink technology in the world, today announced a
breakthrough technology with its Advanced Color ePaper (ACeP), a high
quality, full color reflective display. For the first time ever, an
electrophoretic display (EPD) can produce full color at every pixel
without the use of a color filter array (CFA). ACeP sets a new standard
for bright, reflective color achievable with EPDs. The initial target
application for ACeP will be for digital signage.

ACeP achieves a full color gamut, including all eight primary colors,
using only colored pigments. The display utilizes a single layer of
electrophoretic fluid, which is controlled using voltages compatible
with commercial TFT backplanes. The fluid can be incorporated into
either microcapsule or Microcup® structures. The richness of
the colors is achieved by having all the colored pigments in every
picture element (pixel) rather than the side-by-side pixel colors
achieved with a CFA. This eliminates the light attenuation, which can be
quite significant. Like regular E Ink ePaper, ACeP maintains the
ultra-low-power and paper-like readability under all lighting conditions.

“At its heart, E Ink is a materials and technology company,” said Frank
Ko, Chairman of E Ink Holdings. “It’s this core that provides the energy
and the foundation for the stream of products being developed at E Ink.
We expect ACeP to become the basis upon which another generation of EPD
display products can be developed.”

In developing ACeP, E Ink researchers solved the very complex problem of
how to get reflective color at every pixel in a commercially viable
structure. Other approaches have utilized stacked backplane structures
that are complex, difficult to manufacture and costly. The E Ink
approach utilizes only a single backplane. Many materials and waveform
inventions were required to independently control the position of the
multiple color pigments.

“The technical team was convinced this was achievable,” said Michael
McCreary, CTO for E Ink Corporation. “E Ink’s global R&D team has a deep
understanding and experience with electrophoretic displays. During the
years of hard work applying this experience to full color, the
breakthroughs required to achieve this milestone were numerous and
frequent. We are very proud of the team’s accomplishment and dedication
to this task.”

Multiple 20” displays with a resolution of 1600 X 2500 at 150 ppi have
been constructed. ACeP will be on display during SID’s Display Week at E
Ink’s booth (#521) at the Moscone Conference Center from Tuesday, May 24
through Thursday, May 26.
