TECHNOLOGY
Thin Liquid Crystal Cell Gap
Another important factor allowing for the high
contrast of the SXRD projectors is the SXRD panel’s
ultra-thin cell gap of less than 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 panel 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
panel, these artifacts are not seen.
Short Response Time
The thin cell gap structure in SXRD panels also
contributes to an ultra-fast response time of .
milliseconds (for both rise and fall). The SXRD
panel reacts promptly to an instantaneous
change of picture content, enabling it to display
smooth motion. Consequently, the SXRD projectors
virtually eliminate motion blur; a particularly
significant benefit when presenting content that
includes fast-moving objects.
Inorganic Alignment Film
The SXRD projectors use extremely bright and
highly powerful lamps. As a result, special
attention has been paid to the reliability of the
SXRD panel. The inorganic materials utilized for the
alignment layer of the SXRD panel are resistant to
deterioration or deformities that could occur due
to the intense heat and light generated by the
powerful lamp system.
Thanks to this SXRD panel, Sony’s SXRD projectors
can offer extremely bright and high-contrast
images with minimal blurring of moving pictures.
