This is interesting, but I really thought flexible and printable electronics would have been given more practical uses by now.When I gave my EE report on the future of printed electronics, my vision was definitely a lot more vast than a novelty phone; I'd expect LG to take better advantage of the tech if one EE student can come up with better uses (not tooting my horn; shunning LG for lack of innovation). I gave that report 2 years ago, now.I'm sorry, I just don't see any practical application here. Samsung's Nexus S 4G was curved, and that was nifty and comfortable, but other than being able to bend the phone to your face and the initial novelty effect, this seems pointless.

Samsung demoed the same tech in 2010 at CES:

I was thinking they might be a bit more creative, like using a flexible synthetic network of nerves to control carbon nano mesh for use in prosthetic "muscles", but I guess a flexible phone is more profitable. See: http://www.wired.com/wiredscience/2009/03/nanomuscle/

Just because you can, doesn't mean you should. I look at this the same way I look at that curved television put out by whoever a short while back - is this really the best way they could possibly come up with to use their funding? Aren't there better things to be doing than handing off design tasks to the marketing department so they can pile more gimmicks onto their phones?

I understand this due to comparison with other "HD" phones, but to be real: at a screen size that small it's literally impossible for your eyes to see the difference between 720p and 1080p. The LED density and pixel density can make a difference, but the resolution alone doesn't actually mean much.

Generally, on TVs the rule is that 6ft or greater viewing distance on a screen size under 40in the differences between 720p and 1080p are *nearly* imperceivable. I'm not sure how it applies on hand-held viewing distances, but try viewing a 720p video and a 1080p vid of the same movie/show etc. on an iPad retina display. If they're both truly the correct resolution and bit rate, you won't be able to see the difference, because the pixel density (PPI) is what matters.

This article does a fairly good job of explaining this: http://www.tested.com/tech/371-why-pixel-density-matters-more-than-just-screen-size-or-resolution/

1080p is really a novelty and bragging right on phones; 720p is more than enough.
