Multi-zone scanning technique unlocks potential for brighter, higher resolution displays with wider field of views
BOTHELL, Wash., Aug 18, 2004 (BUSINESS WIRE) — Microvision, Inc. (Nasdaq:MVIS), a leader in light scanning
technologies, today announced a new, scalable, architecture for its
microdisplays in which a single scanner is used to direct multiple
beams simultaneously into separate zones of an image. The new
architecture has the potential to deliver a bright, high resolution,
image over a very wide field of view creating an immersive
“big-screen” effect that is highly desirable for applications such as
personal theatre and gaming. Because the display utilizes conventional
“surface emitting” LEDs as light sources, it holds the promise of
achieving very low cost relative to display resolution and brightness.
The engineering prototype uses a few tens of LEDs to write
approximately 7.6 million red, green, and blue spots that integrate to
form a single high-fidelity image. In the current prototype, the
company uses an existing scanner and drive electronics to deliver all
7.6 million pixels into a 1.4 million-pixel frame, to create increased
brightness and enhanced image quality. The array architecture can
alternatively be configured to provide increased spatial resolution.
The resulting color fields are overlapped in a series of zones using a
third generation MEMS scanner that no longer requires the bulk and
cost of a vacuum package. The display delivers an image with a full
30-degree horizontal field of view and has the potential to be
significantly brighter than earlier microdisplay prototypes with
narrower field of views.
“This is a major milestone in the development of color
microdisplays for consumer products,” said Steve Willey, President of
Microvision. “With our earlier single channel architecture, we are
approaching a practical limit in field of view of around 25 degrees.
Now we have the flexibility of increasing display performance by
adding inexpensive LEDs and writing multiple zones. This architecture
gives us the potential to achieve much wider fields of view and higher
resolution necessary for the higher performance imaging and consumer
products we are targeting.
“The architecture evolved from our earlier work with multi-line
image writing that used conventional laser sources. It’s very scalable
and allows us to take advantage of the benefits of declining costs of
memory, processing power and most significantly, inexpensive and
increasingly bright LEDs. Patent applications that cover many of the
basic elements of this approach are among the most recent additions to
Microvision’s IP portfolio, which now numbers 102 US patents, plus
over 90 pending U.S. patents and more than 300 invention disclosures.
We believe the new architecture has tremendous market potential,
particularly for those microdisplay applications that flat panel
suppliers find difficult to address.”
