Get an eye exam?]]>Jun 10th 2010 4:06PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/The problem with those OLED's assuming that it is the same as the Nexus One is that they only contain two colors per pixel, green and either red or blue. So the DPI is actually lower than 250, not that it doesn't look good but it's really an odd setup.

Funny, no one was bothering to talk much about PPI until recently. I guess we were perfectly okay with an average of 80-100PPI displays on almost every one of our devices until just recently.

Now, all of a sudden, 220, or 250 isn't enough. We must have 300.

Which, by the way, is about 150 less than displays used specifically for things like medical imaging. You see, in your pocket, you need 300PPI for farmville and fart apps, but doctors only need 150 to determine when and where to slice into your brain.]]>Jun 10th 2010 4:11PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

I don't have Apple, I owned an iPhone for over two years. I understand why Jobs has to say that the display on the iPhone 4 is the best, but I still dislike the fact that he is essentially being dishonest to his customers and to himself when he states that LCD tech is better than OLED. It isn't. LCD has peaked, and then some, whereas OLED is already showing the potential for amazing contrast, brightness (in Super AMOLED), viewing angles, response time, and power usage, only in it's first few years of production.

Think about how long LCD has been around, how terrible it used to be, how many improvements it has seen, and then consider the potential of a technology that, only in it's infancy, has almost surpassed it in just about every way.]]>Jun 10th 2010 4:19PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

The thing about AMOLED and OLED displays is it can produce colors that an LCD never could. Even on the Froyo contact page on the Nexus one, the Neon color icons when seen in the dark could NEVER look like that on a normal LCD.

And THAT is contrast ratio. Really, thats whats making things look so damn good now in days. DPI is a bit overrated at this point. The Nexus One stepped it up a bit, but really, thats all we needed. Anymore is just for a few kicks. For god sakes, we still use 1080P on our HUGE TV's and it looks clear. ]]>Jun 10th 2010 4:30PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/Jun 10th 2010 4:30PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

Totally wrong. AMOLED stands for Active Matrix OLED, which every current OLED display is. The alternative is Passive Matrix OLED, which doesn't really work (really bad lifetimes) and isn't used anywhere, so in practice "OLED" and "AMOLED" are interchangable.

The only difference between the Zune and Desire is the crazy pixel layout.]]>Jun 10th 2010 4:36PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/Jun 10th 2010 4:39PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/
PPI is what you talk about when your screen is so small you can't see any detail. That's what this all boils down to. This is their way of putting a positive spin on the fact that shrinking an HDTV down to handheld size might not be terribly useful in practice.]]>Jun 10th 2010 4:41PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/oled and amoled are the same technology the only difference is that amoled uses multiple driver chips within the display frame to control the display instead of one chip away from the display (like on the cellphones logic board). it has nothing to do with the colors or the pixel density itself or even with how the display creates the image.]]>Jun 10th 2010 4:41PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/OLED; he said that the particular display used in the iPhone 4 (Retina Display) is better than the OLED screens that are out there currently. Which is accurate.

I mean, really. Are you suggesting Jobs is like an LCD evangelist? If/when OLED can deliver clearly superior displays for the iPhone, Apple will use it. Period.

I think PPI is much more important on small displays (like a phone) than it is for larger displays (like a desktop monitor or TV).

Uhhhh... He said IPS is better than OLED because he's trying to sell PHONES, not because it was true or not.

Of course, a 4.3 inch 800x480 screen is also a better aspect ratio for ebooks, ecomics and 16:9 content as well, but if Apple had the same 960x640 resolution but on a physically larger display, it would more or less make the iPad pointless to some.]]>Jun 10th 2010 5:04PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

Oh, you mean kind of like how everybody was fine with good LED backlit IPS panels until we found out that the iPad had one, and then suddenly LCD panels make your eyes bleed, they make you go blind, etc. etc. etc. Kind of like that?

The difference here is that 326 PPI is significantly better than any other phone out there, and it shows when you look at it. ]]>Jun 10th 2010 5:13PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

Everyone was fine with IPS panels? You don't really know what you're talking about, do you?

IPS panels haven't ever been "fine". They've merely been "okay", a band-aid on top of a broken tech that, like any other band-aid for LCD tech, has it's ups and downs.

You haven't heard about the poor panel uniformity (u2410, 2209WA, ea231mi), poor contrast (ZR24W, which I'm typing this on), severe off-angle glow (ZR24W), high power usage, aggressive AG coatings, or semi-poor response time up until, what, a year ago? These are all problems that exist on IPS panel LCD's *Today*. Not years in the past, today, on displays being sold right now.

For most people that buy them, they're merely acceptable. They aren't the holy grail of display tech, they're just better than the race-to-the-bottom crap TN panels that every other manufacturer has been churning out, and they *all* have to be hardware-calibrated for spot-on color accuracy.

Go read the [H]ardforums display section, and check threads for any of the IPS displays being sold. You'll find just as much complaining about quality issues inherent to LCD tech as you will praise.]]>Jun 10th 2010 5:22PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/Jun 10th 2010 5:22PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/Jun 10th 2010 5:24PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/

As my hobby is computer gaming i can say PPI are more important to bigger displays rather in smaller ones. I have an SE X1 with 312 PPI and 22 inch monitor with 90 PPI. I can see on both the the pixel if i start to look closely. The advantage of high density of pixel in a display is that eliminate the need of anti-aliasing. So the higher the resolution the less AA you need. This is great for gaming. Another nice of high pixel density is that on my X1 even the SD videos look like HD ofc if i look close i see again pixels. The idea of PPI is the higher the density the more real-life they look. However i agree with grumbles and i have to say that although IPS is very good tech it comes nowhere as good with a equivalent good OLED tech. Having on a small screen high PPI is nice but not important. I would prefer a 24 inch monitor or a 40 inch TV with 300-400 PPI and even more.But whom i kidding still there aren't ]]>Jun 10th 2010 5:33PMhttp://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/http://www.engadget.com/2010/06/10/iphone-4s-retina-display-claim-put-under-the-math-microscope/
