Video Compression?

That's a strange note... DLP is at several hundred hertz.

I have a question about DLP. For DLP TVs, you can't see the subpixels, can you?
If true, i find that very hard to believe that it runs at several hundred hertz because we have one of those black-and-white power saving tv-radio-cd player all-in-one things for hurricanes, and i doubt it would use the power of 6 C-sized batteries to run at hundreds of hertz. Wouldn't it be cheaper for both the manufacturer and consumer for there to be an LCD since those save much more power?

And a little question about LCDs, how come LCD TVs are like 5-8cm thick and my laptop LCD is somewhere near 1cm thick, if just that?
