A Look at Samsung's Curved Smartphone Concept and 4.99-Inch 1080p AMOLED Display

I got a chance to look at some of Samsung Displays' new and upcoming products, probably one of the highlights of my CES 2013 experience. There's a bit to go through, but first up are their buzzworthy curved displays and a concept phone or two. I spent three years in my undergrad optical and electrical engineering education working on curving a CCD for use matching focal planes, and thus curved displays are instantly near and dear to me as interesting next steps.
Samsung was showing off a single-axis curve in their demo room. First is a larger size display with a relatively small bend radius. It's a hemicylindrical display designed for signage.
Next are two smartphone concepts. I've been wondering for some time what curved (not necessarily flexible) displays would enable or look like for a smartphone, and Samsung's concepts are actually pretty innovative looking. The two concepts have a bend on the horizontal or vertical axis — a bend on the right side, or bottom. Then a flip cover covers the planar section of the display while leaving the curved section exposed. This ostensibly allows glanceable information, notifications, and messages to be displayed without requiring a user to flip open the whole phone, and with AMOLED this section can be lit up without having to light up the entire display for saving some power.
The bend radius on these two isn't very extreme but looks like it could be a compelling example use case for a smartphone design. I don't expect either of these designs to come to market immediately, but it's clearly something on Samsung's mind for future products. The entire touch layer and display glass is curved with the display underneath.

Although we originally had more specific information, I strongly suspect the rumored 4.99-inch 1080p AMOLED display will find its way into whatever Galaxy S 4 ends up being.

267ppi (Note 2 RGB) to 440+ in one generation? That's pretty farfetched. Note that the 310 number they're highlighting is from the Pentile S3, *not* the Note 2.iwod - Sunday, January 13, 2013 - link
I used to think 300 PPI were enough, but since i could spot the difference 300 PPI and 400 PPI, and also 400 PPI and 500 PPI, How many PPI is really enough.There are things that can easily go unnoticed. Partially because our brain filter details out. But for Fonts, especially CJK, they are very noticeable.

Over 9000 should be enough.jamescox - Monday, January 14, 2013 - link
I have tried looking at some displays with a regular magnifying glass, but I can not differentiate sub-pixels without significantly higher magnification. I can often see the pixel grid, but white pixels still look like a white square; I cant differentiate the RGB sub-pixels even on a normal, low ppi display. I was wondering what magnification you actually need for a high ppi display.
Also, if you had a cylindrical display, but with it curved around the viewer, would this require changes to how a 3D game is rendered, or would it still look correct even though the rendering is using a flat rectangle as the view?
