Thin Liquid Crystal Cell Gap
Another important factor allowing for the high
contrast of the SRX-T110 and SRX-T105 is the
SXRD device’s ultra thin cell gap of less than 2
micrometers. With conventional ‘vertically aligned
liquid crystal’ systems, a thin cell gap could not
be achieved. Sony has overcome this difficulty
through the use of innovative planarization
technology in the silicon backplane structure
and an advanced silicon wafer-based assembly
process.
The SXRD device also adopts a structure that does
not use “spacers”. These are columns found in
conventional reflective liquid crystal devices to
maintain a constant gap between the liquid cell
floor and the top of the device. Spacers tend to
both scatter and reflect light, which can impair
high contrast pictures. In the spacer-less SXRD
device, these artifacts are no longer seen.
Short Response Time
The thin cell gap structure in SXRD devices also
contributes to an ultra-fast response time of 2.5
milliseconds (for both rise and fall). The SXRD
device reacts promptly to an instantaneous
change of picture content, enabling SXRD-based
projectors to display smoothly. Consequently, the
SRX-T110 and SRX-T105 virtually eliminate motion
blur; a particularly significant benefit for visuals
that include fast-moving objects.
Reliable Display Device
The SRX-T110 and SRX-T105 use high-power, bright
lamps. As a result, special attention has been
paid to the reliability of the SXRD device. The
inorganic materials utilized for the alignment layer
of the SXRD device are resistant to deterioration
or deformities that could occur due to the intense
heat and light generated by the powerful twin
lamp system.
