720p is fine, why not focus on less strain on the CPU and battery?

AS you can see the pixel on a note 2 is 3 subpixels for each color (blue bigger because that wears out faster)
While in the S3 and S4 2 pixels have only 5 subpixels and they share 1 of them.
It creates a less sharp image. So on this topic its quite relevant .
Those links dont go into the screen PPI for the Galaxy S4 compared to other devices such as iPhone or Galaxy S3
Of course its sharper, 441ppi vs 306ppi, probaby the better pixel struture improves it as well .
Wich is logic of a 2 year old.
Pixels are comprised of subpixels, your own image shows this nicely.
Where make an error is first pull a number out of your hat to set the PPI of the S3 at 285 and then transport this to the S4 wich is a different phone with different structure. Combine this with the fact that because of the less then perfect structure (pixels dont align) you get amore fuzzy image as the pixels dont light up on straight lines.
Now with the higher PPI this is lessened but that goes against the whole purpose of the thread : say the higher PPI is not needed.
Here is a nice example (Super AMOLED as in the S3 and S4) :
They are close together because the PPI is higher, DUH
Sorry but the premise of this thread was that this ISNT needed. You just talked against your own point. :lol:
The site of wich I took the image agrees with me
"The premise of the PenTile creators is that their invention is not inferior to the traditional RGB, but actually a different way to arrange a display matrix, where you lose some definition diagonally, visible at lower pixel densities, but gain brightness, ease-to-manufacture, contrast and power efficiency. For higher pixel densities you stand to gain from PenTile, they argue, and, since this novel arrangement is slowly creeping into both LCD and AMOLED screens of various high-end smartphones, starting with Samsung and Motorola, we'd better check if these claims hold water."

I have nothing against the tech, pentile screens are great screens, but they do deliver a fuzzier screen that gets negated in the S4 with the 1080p screen.
If they had put in a 720p screen with pentile at 5" the screen would have been less sharp then the S3 wich went before it, quite a big goof in such a cut throat market .

You asked for info on pentile, the pos aboce explains more in detail why higher PPI is very beneficial for pentile screens.
Just want to point out, high ppi =/= better screen quality. Sure, the new diamond pentile arrangement may be better than the old, but even that isn't the whole story....
AMOLED is notorious for poor color reproduction - some people like it, others don't. But the simple fact is, the iPhone 5 COULD have a nicer display than say the GS4 due to a variety of reasons....one of the last of which would be related to ppi.
Case-in-point: Simply look at an iPhone 4S and 5 side-by-side at full brightness....tell me you can't see a noticeable difference in screen quality. Both are 326 ppi, both have the same horizontal resolution. There is technology behind the screen that drives quality more than simple spec sheet marketing terms...in this case, they used a new laminating process and cut out much of the space between the LCD and outer glass allowing for a brighter, more color accurate screen while still preserving battery life.
I'm looking forward to Apple's implementation of IGZO - whether they increase the PPI or not. Simply switching to this tech will help the battery life and if they choose, they can cram a ton more pixels in the same space.
I agree with the OP - 1080p, which as a standard has no meaning in the smartphone world anyway - is pointless. Consumers will continue to be tricked, but until a separate HD standard for smartphone sized displays is established (retina is as scientific and as good as any), this "your iPhone can't play HD vids therefore it sucks" nonsense will continue to be spewed.
@OP
What do you think sells better?
Super Artexaplex A42 Hexacore processor
OR
1080p display
?
It's as easy as that. One is nonsense anymore the other is a household name and something everyone has heard of.
As far as I've seen some of these new HTC devices I've seen in store screen does look better then the iPhones side by side. So I think there is something to it. I also have better then 20/20 vision. I don't have any hands on in the real world though.

I agree with this. While having a nicer screen is well, nice, this whole 1080p-on-a-smartphone reminds me of megapixel war that digital camera industry underwent few years ago. In other words, marketing BS.
At some point, you hit the law of diminishing returns.
In digital camera example, higher megapixels (without increasing the size of image sensor or radically improving it) will eventually result in inferior image quality (higher noise) and much larger image size (and thus wasting both storage and bandwidth to transfer images) than would be needed.
For smartphones, 1080p further fragments the platform, offer minor visual improvement over 720p for most (much less than improvement in color reproduction, dark level, etc.), and putting strains on CPU/GPU, storage space, memory, and/or battery life (or at the very least, some or all would have to be improved as counter).
I would much rather have the industry focus on dramatically improving the battery life, usability, and durability.

You can have 20/20 vision and be farsighted, meaning you can't see things clearly that are close to you like your cellphone screen.
Ok?
It's early so maybe I'm missing the point you are making to me. If I was far sighted I'd want a bigger screen device that I could see better. I watch movies on my iPhone nearly every day waiting in an airline or metro terminal and it strains my eyes.
Edit : Duh 1080p. Yes if I had poor vision I doubt you could notice 1080p on a phone screen. But like I just mentioned if I had poor vision I wouldn't deal with an iPhone screen to begin with.
Just pointing out 20/20 vision means nothing when it comes to a phone which is being viewed arm distance away from your eyes. No one is using their phone 20 feet away from their eyes.
Someone with 20/20 vision might need glasses to read things up close, while someone with poorer than 20/20 vision can see things up close really clear.
So saying you have better than 20/20 vision is kinda pointless as we are talking about cellphones.
The same stupid masses who fall to marketing then complain everyday about them having to charge the phone too often.
Seriously, 9mm is fine as the default thickness. Use that space to put more juice inside instead of making it thinner.
