Are LG, Samsung "Curved Display" Smart Phones Like "Smart Watches"?

It's fair to say there is quite a bit of debate about whether the first generation of smart watches we now are seeing is interesting, much less a big or disruptive market. 

It probably is way too early to conclude much of anything, as even other very popular consumer and digital technologies had very little adoption in the first year or two. 

Now smart phones with curved displays appear to be coming as well. That innovation might not have great impact initially, either. And again, it will be too early to tell much of anything, at first.

Curved handset displays appear to be coming from LG Electronics and Samsung Electronics. as curved screens have appeared on TV sets as well. Apart from aesthetics, it is not so clear what the advantages are. 

Curved screens sometimes are used by really large movie theater screens, in part to "focus" more light toward the audience, and in part to reduce optical distortions when using certain projection lenses.

There's also a potential "naturalness" to an image that has every part equidistant to your eyeballs. But that is largely an advantage limited to small spots, when in front of a very large screen. 

But perhaps the most notable benefit is the ability to fill a massive percentage of a viewer's field of view, in some seats, where an image wraps around the viewer. 

It is not clear that such an advantage is possible using a small screen. 

And that might be an issue to be overcome, if either smart watches or curved screen devlices are to gain traction. What is the advantage? 

In the future, if and when very-flexible, thin screens are available, what other form factors might be conceivable? And how thin, how flexible and how cheap would such displays have to be to create lots of new value? We will likely find out first in the business-to-business markets, for reasons of cost.
