Doctor says Apple exaggerated claims on its "Retina Display"

Doctor says Apple exaggerated claims on its
The display on the new iPhone 4 shatters the record resolution seen on some of the newer Android models. While the Motorola DROID has a resolution of 480 x 854, Apple's redesigned touchscreen device flaunts a display of 640 x 960. Because the latter handset has a 3.5 inch screen vs. 3.7 inches for the former, the number of pixels per inch (PPI) is 326, a number that the manufacturer claims surpasses the 300 PPI that the human eye can distinguish. However, an expert on screens, Dr Raymond Soneira, says that Apple has exaggerated the claims about its' self-named "Retina Display". Dr. Soneira runs DisplayMate Technologies, a company that makes software to test displays. In an e-mail he sent to PC World, the Doctor said that while the display on the iPhone may be the best in current production on a cellphone, it does not show more pixels than the human eye can process. The Doctor wrote, "Steve Jobs claimed that the iPhone 4 has a resolution higher than the retina - that's not right: The resolution of the retina is in angular measure - it's 50 Cycles Per Degree. A cycle is a line pair, which is two pixels, so the angular resolution of the eye is 0.6 arc minutes per pixel; So if you hold an iPhone at the typical 12 inches from your eyes, that works out to 477 pixels per inch. At 8 inches it's 716 ppi. You have to hold it out 18 inches before it falls to 318 ppi."

So according to Doctor Soneira, you would have to hold your iPhone 4 about 1 1/2 feet in front of you before Apple's claim is true. And even then, for the iPhone to deliver an image that appears perfect to the eye, it would have to have a resolution greatly higher than the retina and that is not the case. The Doc says that the iPhone's resolution is "significantly lower" than the retina. He adds, "It's a great display, most likely the best mobile display in production (and I can't wait to test it) but this is another example of spec exaggeration." As we reported yesterday, Samsung claims that the Super AMOLED display on its Galaxy S handset is superior to the display on the iPhone 4. A verdict will have to wait for a side by side demonstration.

man it's like that with everything nowadays - just like with cars "We have a 5 star crash test rating!" only in one category and the rest are like 1 and 2 stars - just shows that consumers need to do more research before purchasing products

Yes... this is how I bought my nokia 5800. They told me "it's just like the iPhone".

Also something to consider is to take a step back and think about exactly what Phone Arena decides to throw out. If they decided to post something about a doctor who says the retina display isn't over exaggerated, then people wouldn't care. But with an article like this, of course its going to get people to think "oh wow, the display isn't good". This is not something to really take much into consideration and rather consider doing research more on the number of doctors agree and disagree with this.

@ilia yes it is like an iphone, it has a big screen no keypad no anything and they are both full touch handsets. . maybe that's what Nokia is trying to tell you. . ahahah but the software on the iphone is better, but Nokia has a lot more features and 3 times cheaper than the overpriced crapple, buy a cheap phone, and a itouch 8gb,and you get almost the same features on a cheaper price. . . :D sure the iphone has bluetooth blah blah and stuff. . . but it's too overpriced. . an itouch costs significantly cheaper even the 16gb. . let's say the iphone 16gb costs around 33,000 pesos the itouch 16gb costs 13,000 pesos. . making the itouch a bang for your buck. . iPhone lovers love the software itself (due to smoothness and blah blah) I also like it too, but too overpriced. . . the iPhone 4 as far as I can see will be overpriced. . . why not buy the n8 or the satio or samsung galaxy S. . . and I know the price of these phones and the crapple would not a big difference. . and they bring bigger and better features. . like the samsung's 4 inch AMOLED screen, Satio's 12 megapixel and Xenon Flash and Nokia's symbian^3 is worth a try and HD recording plus the megapixel seems to be the rage these days. . :D and Android phones are so much fluid than the MAC

yup. never listen to the hype. let the early adopters try it first and work out all the bugs for you. give it a few months before buying anything brand new. the truth will seep out between the cracks rather quickly.

I am sorry but this dude sounds like a complete hater. The resolution is the awesome, how about he worry about his patients then a phone.

Don't worry vette, he's also an idiot! " Dr. Soneira runs DisplayMate Technologies, a company that makes software to test displays." He is worrying about his patients....HE WORKS ON SCREEN DISPLAYS!

now for me ... yes you shouldnt have a name that has i love the i phone in it... and then go comment on forums and post that the i phone is the end all be all and any critic is a "hater" all this article says is that this man is a dr. and a expert on how the eye works. I dont think he did it to lash out and say that the i phone is bogus and tricks your vision and that jobs claims are out of wack... i think that as a student of his profession probly for a number of years .. doesnt like incorrect information out there. There is always a sales tactic for new technolgy in this case.. and jobs embelished a little.. its still amazing resolution for a cell phone and im pretty sure thats what jobs was trying to get across. the dr. is not a hater, hes just putting facts against improv so to speak. dont hate him, hate jobs for duping you into thinking your i phone is space age technology. doofus.

It's typical to have ppl come out to say the opposites. It's just like if A says sort-and-sort can cure or help preventing cancer, B or a doctor out of nowhere will come out and say that it is not true... I guess doctors also could use this as a strategy to boost their fame in the world, haha

People always have to have something to complain about. The display is awesome and that's all that matters.

Wow this is getting to be stupid this goes to show that some people just want apple to fail or be proven wrong. if a doctor has to go through the trouble of proving something wrong who cares don't you have patients people who need serious medical treatment. Next thing you know construction workers will be testing to see if it stainless steel. Get a Life people

You must not be the sharpest knife in the drawer. I say this because this doctor doesn't have patients. PLEASE READ COMMENT 11 and go get a life.

You fanboys are ridiculous. There is nothing wrong with this doctors report. It helps keep things honest. He never said It wasnt are great display. If people didnt question claims It would be just like the diet industry with a bunch of false claims.

"If people didnt question claims It would be just like the diet industry with a bunch of false claims." Besides that, it's human nature....we like to ask questions.

Hehe, I agree. I think the doc's comments are spot on. Just the facts, ma'am.

I agree with the hype thing. Take the EVO 4G for example. They pitched it as this amazing phone that could do just about anything and a true iPhone killer. But in reality... oh wait, um, actually, yeah, it kinda hits the mark. Never mind, I guess I am pretty stoked about it living up to the hype! ;)

Iphone killler yet sprints network cant handle enough Evos to be an iphone killer. Nor do they have the customer base to sell enough.
