Measured response time of the SXRD panel is less than 2.5 milliseconds.
Specified response is 2.5 milliseconds for the rise time (tr) and also 2.5
milliseconds for fall time (tf). This speed means incredibly clean motion
rendering.
Contrast, an essential requirement of any display system, is measured as
the ratio between the brightest possible bright and the blackest possible black.
Sony's SXRD panels achieve superb contrast ratio, thanks to three distinct
innovations.
• Sony-designed Vertically Aligned Nematic (VAN) liquid crystal. Most H-
LCD projectors use Twisted Nematic (TN) liquid crystal, which normally
displays white. Sony achieves higher contrast because the SXRD panel uses
VAN liquid crystal, which normally displays black. This crystal material is
proprietary to Sony SXRD devices.
• Ultra-thin LC layer, less than 2 micrometers. The contrast ratio is defined
in part by the "dark level"—the blackest possible black that the panel can
display. Lower dark levels are better. As with response time, the dark level
falls dramatically as the LC layer thickness is reduced. For this reason,
Sony's ultra-thin LC layer—less than 2 micrometers—contributes directly to a
higher contrast ratio.
