I couldn't make it to SID Display Week this year, so I consider myself lucky to have found this photo on the Samsung Flickr account.
That 10" screen is based on tech developed by Liquavista, Samsung's newest subsidiary. It uses Liquavista's proprietary electrowetting screen tech. The last I heard is that this screen should hit the market in fall 2011, but that is a little old. It could have been bumped back again.
That's a screen that I didn't know Samsung were working on. It's based on the MEMS tech, and the only other place it's used is in Qualcomm's Mirasol. (I'm looking into it.)
Samsung also had 6.2" demos for all 3 of Liquavista's screen; they're after the break.
