I am hearing smartphones are going to get 1280x720 screens!

Now these screens are also going to be 4" so at 1280x720 resolution wouldn't the screen be too small?

See: iPhone 4.

"Too small" is all relative. It's about increased fidelity. Yeah, at the 3.5" diagonal resolution of the iPhone display, 1280x720 is overkill, at 4", it would probably be a "maximum reasonable" resolution. After seeing an iPhone 4 display, I would have liked it if the Droid X / Evo 4G's physically larger displays had been 1280x720.

And to think we used to be happy with 640 x 480 screens in the olden days! :eek:

tbh I had a plain 3G and the screen was fine. Now, I'm not arguing over it; I'd love to have a sharper display. But for some things it really can just be bragging rights.

The Dell Thunder (or is it Lightning) is an Android phone that will be getting a screen with that resolution.

What does it matter? You can't possibly make the display itself more noticeably sharp than the iPhone 4's. Its pixel-density is the boundary of human perception. It's like making a black hole blacker. What's darker than something that actually entraps light!?

oh but you can. That is the limit at 18-20 in. reduce that to 12in and apple iPhone4 has a little ways to go.

Also it seems that the 3.5 in screen apple uses is quickly being determined to be to small and the people seem to like the 4in screen size.

18-20 inches...as in distance from the screen to the users' dopey face?

No matter how I look at the iPhone 4, I am unable to distinguish a single pixel. Once it is within four-inches, it becomes impossible to focus and, thus physically impossible to accomplish.

Also, we're talking pixel-density, not pixel amount.

seeing a single pixel and it appearing better are 2 very different things.

At 20+ in from my face I can not see a single pixel on my iPod touch but compare that to iP4 the iP4 looks a heck of a lot better. Things would just look better.

The other thing is like I said before we are still trying to figure out the idle phone screen size. It seems 4 in seems to be the sweet spot for people. iPhone 4 3.5 is little on the small side for a lot of people.

No. Not even Jobs claimed that the iP4 display is at any absolute boundary of visual perception.

What he was repeating was a common rule of thumb that at 12" and over 300ppi, a person with normal (but not extremely good) eyesight could not make out individual pixels... that is, their retina could not physically make the distinction.

That's what gave us the historical idea of 300dpi being called "print quality". (Of course, today's laser printers give even better resolution, and you can indeed see the difference at times.)

What's your eyesight? Nearsighted folk can see pixels VERY easily at such a close distance.

The whole point is that eyesight resolution is not an absolute number. Not only does it differ between people, but the definition itself gets strained when you're talking about the ability of the eye to move around and "see" more than a simple snapshot, plus the brain's ability to merge and smooth information, plus a whole physical subset of research into what the eye really uses to figure out colors, luminance and boundaries.

I have 20/12 vision and I cannot distinguish pixels a foot away, unless I let my eyes go out of focus.

If you don't like the iPhone 4, don't buy it.

WTF does this mean.

I almost translate this as if I do not worship at the church of apple shut up. Nowhere did I say I did not like the iPhone. I just was pointing things out in where the market seems to be going in phone size and resolution. Phones have been growing in average size for a long time and they seem to be looking for the sweet spot between portability and usability. 3.5 in you can only put so much info on the screen not matter what you resultion.
For example on a 4pm galaxy S screen it can and does put more information on the screen than the iphone due to the larger screen size. The iPhone 4 can only put the same amount of info on the screen as the 3GS. It just looks better but same amoun of info. Limitation is physical size of the sereen.

There is going to be a range of size that people will like. 3.3 to I say 4.5 when it is all said and done
