Short response time
The thin cell gap structure in SXRD devices also contributes to an
ultra-fast response time of 5 milliseconds. The SXRD device reacts
promptly to an instantaneous change of picture content, enabling
them to display a smooth motion.
Consequently, the SRX-Series projectors virtually eliminate motion
blur. This is a particularly significant benefit for visuals that include
fast-moving objects.
Reliable imaging device
The SRX-Series projectors use high-power, bright lamps.
Consequently, special attention has been paid to the reliability of the
SXRD device. The inorganic materials utilised 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.
Thin liquid crystal cell gap
Another important contributing factor in the high contrast of the SXRD
projectors is the SXRD device’s ultra thin cell gap of less than
2 micrometres. With conventional Vertically Aligned Liquid Crystal sys-
tems, a thin cell gap could not be achieved. Sony has overcome this
difficulty through the use of innovative planarisation 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 spacerless SXRD
device, these artifacts are no longer seen.
