PALO
ALTO, CA -- (MARKET WIRE) -- 04/21/2005 -- Nanosys
announced today the issuance of U.S. Patent No. 6,864,626
(the '626 patent) entitled "Electronic Displays
using Optically Pumped Luminescent Semiconductor Nanocrystals,"
by the U.S. Patent and Trademark Office. The '626
patent is part of a broad set of nanotechnology patents
that Nanosys has exclusively licensed from the Lawrence
Berkeley National Laboratory and covers electronic
color displays based on an array of semiconductor
nanocrystals.
The
technology described in the '626 patent utilizes different
sized nanocrystals specifically designed to emit light
of different colors, such as red, green and blue.
The nanocrystals are grouped into pixels and optically
pumped to produce a full-color image. Optically pumped,
multi-color nanocrystal displays offer many potential
advantages such as their exceptional color accuracy
and viewing angle, high efficiency, and compatibility
with conventional display manufacturing processes.
The technology can also be used to replace traditional
LCD (Liquid Crystal Display) color filters as a new
form of color-changing medium to produce OLED (Organic
Light Emitting Diode)-like display quality with the
simplicity and reliability of an LCD.
"The
technology behind this patent has the potential of
creating displays with the best features of OLEDs
and LCDs combined while preserving manufacturing simplicity,"
said Calvin Chow, Nanosys' Chief Executive Officer.
"The applications for high performance displays
such as portable electronics and large screen televisions
are huge, and we're extremely excited to have such
an enabling technology to address these opportunities."
The
licensed '626 patent complements Nanosys' other exclusive
patents including U.S. Patent Nos. 6,322,901 and 6,861,155,
which cover some of the earliest work in basic core
shell nanocrystals for highly efficient light emission.
