What would SID be without cool and different new display technologies and ways to use them?
This see-though display from Microvision  provides a HUD for anyone from a soldier needing a SITREP to a mechanic looking up a technical manual for the engine they're working on.
Semi-flexible displays were also all over. Here are some from Samsung .
This is a reflective bistable (it only uses power when changing the image) Cholesteric LCD from Kent Displays . The rugged and thin display technology will enable color e-books, among other things.
LCDs weren't the only curved things. This display (to be released at the end of the year for about $5k) uses an Osram  LED-based rear-projection Texas Instruments  DLP light engine to create a widescreen curved image.
Non-rectangular LCDs seem to have appeared out of nowhere, here evidenced by round LCDs from Toshiba  and a heart-shaped screen from NEC . I can think of a ton of applications that would benefit from a non-traditional shape.
