time [ms]

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.

High contrast, low dark level

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.
