iPhone 5 Display Vs. Spectroradiometer

According to Apple, the iPhone 5 offers 44% more color saturation than the iPhone 4S. Jeff Yurek of dot color decided to put the claim under direct scientific inspection, and found out (through a spectroradiometer) that, indeed, the display is remarkably improved.

The 44% more color claim for the iPhone 5 is the same claim Apple made for the new iPad. As with the iPad, increasing the color performance of the iPhone 4S by 44% of NTSC 1953 gamut, measured using the CIE 1931 color space, would result in color saturation matching the sRGB color standard. Using these standards as the goal posts, we measured the iPhone 5 at 70% of NTSC 1953 in CIE 1931, a 39% increase from the iPhone 4S, which measured at 50%. That’s 5% less of an improvement than Apple’s 44% claim and just 99% of sRGB (measured against the sRGB primaries). While 5% less might seem like a big deal, getting to 99% of sRGB is a major feat and will result in tremendously noticeable color improvement in the phone. Additionally, color filters are notoriously difficult to manufacture.

I am no display expert, but from personal experience I can say I see a definite improvement of blues and greens on the iPhone 5. Just by looking at the App Store, Phone, and Messages icons on an iPhone 5 and iPhone 4S, you can see that the colors are more vivid and “real” on the new device. Yurek’s scientific measurements put this into better context with factual evidence.

Also worth linking is the photo set of retinal neuroscientist and photographer Bryan Jones. He took macro shots of the iPhone 5 and iPhone 4 to compare color quality, then put them both under a microscope to take a look at the pixels. Check out his results here.

The Problems with a Retina Display on the Mac

If Apple were to do something like the above, the biggest question I would have is whether or not they’d put something into place for users who genuinely do want much smaller UI elements and much more screen real estate. That is, if Apple were to double their UI, and then use the 2×1080p resolution for the 27-inch iMac, there’s a sense in which current 27-inch iMac users would feel like they were actually losing screen real estate from their current 2560 × 1440 displays. But that’s why Apple’s Apple and I’m a guy writing about them: if and when Retina Displays do come to the Mac, they will have thought that issue through and either solved it, or decided that the set of users who would be upset by it isn’t a large enough group to hold other users back.

Tim Ricchuiti at The Elaborated makes a great case for the issues Apple would have to overcome in implementing higher resolution displays (let’s just call them Retina Displays for the sake of the argument) on Macs: at 3200 x 2000 pixels (that’s the resolution of the default wallpaper image found in the Lion betas, and no Mac or Apple-branded screen currently ships with such pixel density), UI elements on a MacBook Pro 15″ would look small, unless Apple comes out with a solution to offer same-size graphics, on a higher-res screen. On the iPhone 4, for example, they allowed developers to create “2x” graphics that, with double the pixels on the iPhone 4, look the same size of iPhone 3GS graphics. But how would you do that on a Mac, where users can decide to install apps both from the web and the Mac App Store, thus preventing Apple from enforcing a 2x standard? Plus, how could Apple offer a way to switch between bigger and smaller UI elements? A desktop ecosystem like OS X with computers featuring much bigger displays than iOS devices raises more questions over the implementation and usage of Retina Display.

Make sure to check out Tim’s full article here. Whilst “HiDPI display modes” were previously rumored to be finding their way to new Mac screens relatively soon, we think Apple will have to find a solution to the problems with a Retina Display on the iPad first. [via Daring Fireball]

A new report posted by Joshua Topolsky at This Is My Next seems to contradict the rumors we’ve been hearing in the past weeks in describing the next-generation iPhone — so far dubbed iPhone 5 — as a complete redesign of the existing iPhone 4 hardware. The report comes with a mockup based on sketches and descriptions the website received by multiple sources over the past weeks, and shows a dramatically thinner device with a “thick to thin” design from top to bottom similar to MacBook Air’s main body, and a larger multitouch display set at approximately 3.7 inches. The change in size would allow Apple to keep the existing Retina Display branding with a drop to 312ppi (iPhone 4 features 326ppi, and Apple claims a “Retina Display” can be called so starting at 300ppi on an iPhone), and it’s something that’s been rumored before and even spotted in allegedly leaked Apple design documents.

Our sources say the new model (or at least one of the new designs in testing) looks “more like the iPod touch than the iPhone 4.” The phone will be thinner than the iPhone 4, and may have a “teardrop” shape which goes from thick to thin (something along the lines of the MacBook Air profile).

This Is My Next also claims the Home button will become larger, doubling as a “gesture area” for a series of multitouch commands likely inspired by the ones introduced in the iOS 4.3 developer betas. Apple was rumored to be considering an early departure for the Home button, but the website claims the company has been playing around with various prototypes and design iterations, and one of them indeed sports a larger, redesigned version of the Home button. With a larger, almost edge-to-edge screen, Apple is apparently also experimenting with the idea of earpieces and sensors hidden directly behind the display’s glass:

Furthermore, we’re hearing that the screen on the device will occupy the entire (or near to it) front of the phone, meaning almost no bezel. Our source says the company is doing very “interesting things” with bonded glass technology, and has been exploring designs where the earpiece and sensors are somehow behind the screen itself, making for a device where the display is actually edge-to-edge.

Other details reported by This Is My Next include a “swipe area” for NFC capabilities, inductive charging and world-phone functionality with a global CDMA-GSM chipset. Again, these features have been in the rumor mill before, but This Is My Next’s report is mostly interesting because of the design speculation included in the article that contradicts several rumors we’ve recently heard. And even if the design may never make it to the final version of the iPhone 5, TIMN says it’s being tested by Apple:

The versions of devices our sources are seeing could be design prototypes and not production-ready phones. Still, there are strong indications that Apple will surprise a public that’s expecting a bump more along the lines of the 3G to 3GS — and this is some insight into where those designs might be headed.

9to5mac has posted a photo from Chinese reseller of Apple parts iDealsChina showing a a purported digitizer panel for the next-generation iPhone, dubbed iPhone 5. The front panel shows a bigger display with an “edge-to-edge” screen that reduces the size of the bezels, especially at the sides. iDealsChina writes:

China’s 1st iPhone 5 photo has surfaced! From this photo it seems that the screen size will be larger than iPhone 4. There has been a lot of specualtion about a larger screen and maybe this will be one of the upgrades we will see when iPhone 5 is released this summer.

We heard that more photos of parts for iPhone 5 may be available soon. The part we would like to see is the back of iPhone 5 to verify if the rumored tapered back is true.

Several readers have pointed out that the image could be easily modified in Photoshop, but it also appears to back up the rumors surfaced in the past weeks about a new iPhone with a 4-inch screen “edge-to-edge” buit to face the competition of Android handsets sporting bigger and larger displays. In spite of the problems with a new iPhone resolution happening this year, we heard a few months ago that the iPhone 5 would be a “complete redesign” with major new features, like NFC support. It’s not clear from the photo whether or not Apple could keep the iPhone form factor at the same size and increase the size of the display at the same time.

Why The 4-inch iPhone Screen Won’t Happen This Year

In a great “Doing the math” post, Chris Rawson at TUAW outlines the single reason why the next iPhone won’t get the rumored 4-inch screen:

Apple could work around that issue by slightly increasing the iPhone 5′s width, but there’s another problem. If Apple increases the screen size to 4″ but retains the same 960 x 640 pixel dimensions, the PPI (pixels per inch) value drops to about 289 ppi — well below the iPhone 4 Retina Display’s 326 ppi, and just barely at the threshold of a “Retina Display” level of quality. To maintain 326 ppi, the pixel dimensions on a hypothetical 4-inch, 3:2 screen must increase to the neighborhood of 1080 x 720, plus or minus a few pixels.

App developers would then have three sets of resolutions to support for the iPhone instead of two, and scaling from 960 x 640 to 1080 x 720 wouldn’t be anywhere near as simple as the pixel-doubling that got developers by in the early days before they were able to scale apps up from 480 x 320 resolution.

Apple doesn’t want to lose the appeal of the Retina Display, and on other other hand they can’t come up with a third resolution a year after the introduction of the iPhone 4. That would be hell for third-party developers.

With rumors about a smaller iPhone floating around since last week, the latest report from Digitimes surely is interesting. According to the publication, Apple might expand the next generation iPhone’s screen to 4 inches, mainly to compete with various Android handsets that come with displays larger than the iPhone 4.

Apple reportedly will change the screen size of iPhone to 4-inch for its fifth generation iPhone to compete with the Google Android platform in the 4- to 7-inch smartphone market, according to upstream component suppliers.

The component suppliers noted that the production lines for Apple’s next generation iPhone have begun testing, and Apple is interesting in expanding the screen size to 4-inches to support the tablet PC market as the vendor only has a 9.7-inch iPad in the market.

A bigger iPhone screen would raise questions on the resolution of the device, which is currently dubbed as “Retina” thanks to its DPI on the current 3.5-inch display. Another report from last week suggested Apple might adopt Samsung’s Super LPS screen technology, which offers greater viewing angles and brightness. Engadget reported in January that the iPhone would come with a radical new design which, if the rumors are to believed, would play well with this 4-inch screen theory. Digitimes has a good track record on Apple’s production chain reports, and admittedly a slightly bigger display would be pretty cool in our opinion.

In the past months, other rumors pointed to Apple building an iPhone with NFC capabilities for easy mobile payments (although iOS-to-iOS communication would be interesting, too), dual-core processor and LTE for a summer launch “at the earliest”. Earlier today, a new report suggested Apple has been considering three different iPhone 5 models with one of them featuring a slide-out physical keyboard — again, to possibly compete with Android devices. Last, the iPhone 5 is rumored to be a worldphone with integrated GSM / CDMA antennas.

Does the iPad overheat when used outside under directly sunlight or warm weather? U.S. District Court Judge Jeremy Fogol has thrown out the case, where plaintiffs claimed Apple deceptive Apple marketing. The plaintiffs argued that books “don’t shut down,” arguing Apple advertised that the iPad was able to be read “just like an open book.”  Computerworld reports that this case didn’t go very far.

“The Court concludes that these allegations are insufficient,” Fogel wrote in his order. “At the least, Plaintiffs must identify the particular commercial or advertisement upon which they relied and must describe with the requisite specificity the content of that particular commercial or advertisement.”

I’m not going to outside and roast my iPad on the sidewalk and wait for it to overheat, but with any sort of common sense (or perhaps purchasing sense) you should realize the iPad’s screen is pretty glossy and isn’t desirable to read in sunlight in the first place. The Judge has given the plaintiff thirty days to gather evidence per his request, but what could they dig up? Commenters, do you think Apple any of Apple’s advertisements or website promotions could be sufficient for this case?

With the iPad 2 set to come out sometime in April and Apple reportedly about to announce a media event to unveil the new device in February, the Apple rumor mill is in fully-working state. And when it comes to the next-generation iPad, two are the kinds of rumors that blogs and publications are reporting: Retina Display and faster processor. Lately, we have noticed a rapid increase in the presence of “iPad Retina Display” rumors on the Internet. (more…)

Well in the past 24 hours we’ve had another two rumors regarding the iPad 2’s screen resolution. First there was DigiTimes that reported Apple would up the iPad’s screen resolution to that oft-reported figure of 2048 x 1536. Then Kevin Rose who had previously stated the iPad 2 would have a Retina Display reversed his position with a picture of text messages from his supposed source who said “no change in resolution” which he posted on Instagram.

Then there was also the suggestion that floated across various blogs and publications that Moore’s law suggested the iPad 2 wouldn’t have a retina display. Both DigiTimes and Kevin Rose have dubious accuracy regarding Apple rumors and this vicious back and forth contradictions of rumors regarding the display are certainly odd.

UPDATE: Oddly, Kevin Rose seems to have removed the Instagram photo which is now unaccessible and does not appear in his Instagram feed.

So readers, what are your thoughts on this whole high resolution/retina display on the iPad 2 rumor merry-go-round?
