SXRD - Silicon Xtal Reflective Display

ChooseYourTV Comments
Sony has been able to cut down on
the depth of Projection TV's by 4.25" which isn't much but
is a start to having flatter rear projection TVs. SXRD truely is
an beautiful picture that is worth praise. However SXRD HDTV's are
still high in price compared with DLP. However you will see the
picture stand out next to Most DLPs. Sony has also been able to
break 3000:1 contrast ratio which is a step above all other LCoS
technologies.

SXRD is short for Silicon Xtal Reflective Display. SXRD is Sony's
implementation of LCoS technology. Just as JVC has implemented D-ILA
which is a LCoS technology. SXRD is a liquid crystal display device
for use in projection TV's and Projectors. SXRD is designed to achieve
a panel contrast of more than 3000:1 with high resolution of full
HDTV (1920 x1080) using a silicon backplane.
How
SXRD Works (from sony)
A color accurate lamp beams its light into a color splitter which
separates the light into Red, Green, and Blue beams. These beams
are reflected off the SXRD panels, which have a very thin (2 micrometers)
Liquid Crystal layer sitting on a reflective surface.

Each
beam passes through the Liquid Crystal layer, reflects off the mirrored
backing and reflects back out through the Liquid Crystal, which
passes or blocks light according to the needs of the color it is
controlling. The 3 beams are then recombined and sent to the projection
lens array.
SXRD
Optical Engines maximize picture quality by maintaining equal red/green/blue
illumination paths, which minimizes color shading and maximizes
color uniformity.
How
is SXRD Different then other LCoS Projection tv's:
L-COS
(Liquid Crystal on Silicon) and D-ILA (Digital Direct Drive Image
Light Amplifier) are reflective three-chip designs that appear to
be similar to SXRD technology. However, SXRD technology does have
an advantage - Sony's proprietary manufacturing process.

At
just 2 micrometers, the SXRD panel's liquid crystal layer is extremely
thin. It is constructed using a proprietary "spacerless"
process that allows it to be fabricated without the need for spacers
in the cell gaps. As a result, the thin layer of the SXRD panel
responds ultra fast so the picture remains crisp and clear, even
during fast-action sports like basketball and hockey.
SXRD
technology also has excellent depth, accurate color, and a smooth
image, thanks to narrower cell gaps (exceptional black levels) and
extremely narrow Inter-pixel spacing (0.35im), which eliminates
screen door effects and delivers incredibly smooth color and grayscale
transitions.
