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.

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.
