Comparing SXRD to DILA is an interesting topic. In some respects such as LC layer thickness the two have become more similar. I think Sony also used to use an organic LC material and they've switched to inorganic (similar to JVC). From all of the released literature that has come out both seem very similar from the frontside although the huge contrast difference between the two implies that JVC has done more improvements beyond just using wire grid PBSes (which according to JVC, Sony is also using). So there is a big difference in the frontside that hasn't become public.
From the backside I think Sony is using an analog backplane but with improvements that allow it to run at 120hz. JVC has switched to a digital backplane so this is a pretty big difference although a person could argue that the drive electronics are secondary and that differences in the optical frontside is what's really important.
All in all though, both are the same vertically aligned, polarized, reflective LCOS technology so they (and the whole optical engine) are much more similar than they are different. It'll be interesting to see what happens in the future SXRD/DILA wars. It'll also be interesting to see if/when SXRD matches DILA as far as native contrast goes whether Sony will announce the secret (contrast) ingredient, or if they will continue to keep it secret. My guess is that both Sony and JVC have a vested interest in continuing to keep it quiet in order to keep other manufacturers from gaining entry into this market. So it may be a long time before we really know the full details. Kinda reminds me of an X-files episode
