Dawgbyte,
SXRD is Sony's name for what is essentially a LCoS technology. LCoS/SXRD is a form of reflective LCD technology. LCD technology involves a chip whose pixels are composed of long molecules that twist when an electric charge is applied. That twist determines if light will be blocked or passed through freely. The difference with LCoS is that instead of just passing or blocking light, there is a mirror surface on the back of the chip. When it is in the "pass through" mode, light passes through the front layer, reflects off the back and comes back through the front layer. Unfortunately, in the "block" mode, not all of the light is completely blocked. The advantage of LCoS over transmissive LCD is that by forcing the light to pass through twice, light is more thoroughly blocked so black levels are MUCH better. Transmissive LCDs can be made to block more light by making the layer thicker, but the thicker the layer, the longer time it takes for the chip to react to changes. So, the tradeoff is speed vs. black level. There is simply less need to trade off one or the other with LCoS.
