iPad Retina Display features Super High Aperture pixels, double the LEDs

post #1 of 50
Thread Starter 
Packing four times the pixels into the new iPad's Retina Display has proven to be a challenge for Apple's manufacturing partners, who are utilizing advanced technology like Super High Aperture pixel design and packing in double the LEDs for backlighting.

Insight on the new 2,048-by-1,536-pixel screen has been offered by the NPD Group's DisplaySearch. In a post to the firm's official blog, Richard Shim explained that the new iPad's Retina Display has been difficult for suppliers Samsung, Sharp and LG to manufacture.

The three companies are said to be relying on a production process known as "a-Si TFT," which has proven to be particularly difficult, as Apple's Retina Display requirements are reportedly testing the upper limits of the technology. Shim said that the 264 pixels-per-inch crammed into the new iPad's 9.7-inch screen is believed to be the upper limit of pixel density for a-Si TFT.

Sharp was originally said to be pushing for the third-generation iPad to feature its IGZO display technology. But a report arose in January, indicating that Sharp's IGZO displays failed to meet Apple's standards.

Doubling the pixel density in the new iPad has also forced Retina Display manufacturers to double the number of LEDs for backlighting. Shim said the new screens likely include at least 72 LEDs, which could result in a significant increase in power consumption.

"The slightly larger and heavier case as compared to the iPad 2 suggests Apple is using a larger battery in order to accommodate the high resolution display with more LEDs than the previous generation, without decreasing battery life," he said.




In a separate post, Charles Annis of DisplaySearch explained that the new iPad's Retina Display features Super High Aperture pixel designs. This allows Apple to pack more pixels into the same 9.7-inch screen size without causing cross-talk or affecting image quality.

"SHA is a method of increasing aperture ratio by applying approximately a 3 (micrometer) thick photo-definable acrylic resin layer to planarize the device and increase the vertical gap between the ITO pixel electrodes and signal lines," Annis explained.

SHA technology is said to currently be in use in about 25 percent of LCDs, though that number is expected to grow in the future as super-high-resolution displays increase in use.

Sold my original 64GB iPad for $375 three weeks ago, bought a 64GB 3G iPad 2 on Sunday for $450 and sold it today for $590, and pre-ordered a new 64GB wifi iPad 3. I'm can't wait to get a peek at that lickable display

Jumping from an original iPad to this is going to be quite the upgrade.

can I finally use this thing outside in moderate sunlight and see the screen. I'm tired of having to go find a shadowy spot or slip into video village to look stuff up.

If we can finally see these things outside then its time to move onto our next wish list item. Being about to connect them to our monitor system so we can watch the camera feed from anywhere on set. Get off these antique hand helds

But of course, if Apple chooses to make a TV set, they will fail because as Samsung says, "TV's are all about picture quality" which of course Apple knows nothing about.

It's a fancy way of saying "we put a layer of plastic between the signal lines and the pixels to keep them from interfering with each other."

I got a great deal on eBay and it came with a smart cover. I resold the iPad for the going price of $549 to someone local and the leather smart cover for $40.

It's always fun to scout Craigslist for the overly low priced items and flip them for their actual market value. Basically what Steve Jobs did in the 70's with early computer parts to make money according to the Isaacson biography.

Interesting that you were able to work it that way. My experience was always the opposite. Find it cheap locally and then flip it for more on eBay.

You should've kept the smart cover since I works with the new iPad.

You have a misspelling. You inadvertently wrote you sold it to someone local rather than loco.

Why is that person loco? The retail price for a new one was $829 on Tuesday. You can't buy this model any longer from Apple. Buying at a nearly $300 discount seems perfectly reasonable. There's an eBay auction for the same model and a couple cases that already has 20 bids currently sitting at $600.

I just wonder how he got his off eBay so cheap before the new iPad was released.

If you're having trouble finding them, Best Buy has the 64GB model new at $599. Personally $50 off seems a bit loco to me for a used one.

So is this panel a version of the one Samsung announced back in November, I wonder?

That panel was a 2560 x 1600 300 dpi pentile. If it is, those people on these forums who denounced pentile previously because it was used in Samsung phones, will either have to eat humble pie or forego buying one.

You can see it there if you want to check. I convinced the seller to drop the shipping charges for instant payment and feedback and no insurance needed. I was willing to take the risk.

who, from Samsung, said such a device would fail in the marketplace? if you are alluding to what Moseley said in February 2012, you are simply misquoting him.

speaking of display devices, the Samsung ES8000 edge-lit LED due this year will include, among other things, voice and gesture control and a Webkit-based web browser. sounds rather promising.

1) It's clearly not PenTile because it's not an RGBG display. They clearly show it's RGB.

2) The problem with PenTile isn't because it's used on Samsung phones (or because it's a Samsung technology) but because it's an inferior technology. Essentially uses less power, it's cheaper and thinner than RGB for the same stated resolution, but it has 1/3 fewer sub-pixels which result is less crisp and accurate images.

3) I'm thinking this is LG's IPS tech.I'd wager it's AH-IPS. Samsung doesn't seem much interested IPS these days except as a manufacturer.

If small pixels were so hard, I don't understand why they did not make the display a bit bigger, say 10.5" or 11.3". This would still be a retina display, and the larger size would be a big improvement for media and images such as magazine covers, or plain document reading.

This is a totally custom display anyway, so Apple could have made it any size they wanted.

Also, a slightly larger iPad could have been thinner, by spreading out the battery more. (Power draw would increase a little from extra LEDs, but CPU, GPU, RAM, and radios would all use the exact same power).

Oh, wait.

Eventually we'll see larger multitouch devices, but they won't be iPads and they won't be laptops.

With iOS you can't just alter the display output without also altering the input. Everything would be a little bigger. The whole reason Apple went with 2x resolution is so that current iPad apps would lot as good as they did before by much better once idealized for the new display. Bottom line: A new size wasn't an option.

The rest of the ad-homs weren't necessary BTW and come off as arrogant and childish. The forums are better off without personal attacks on fellow members.

In addition to him mentioning that it was 3G, in your post you copied my post which said that Apple was selling the model for $829 on Tuesday. Apple has always only charges $x29 for the 3G iPad models, which again you already know.

Your posts on AI are frequently trollish which anyone whos been here for more than a month well knows. It often appears that you see the information you want to and ignore the info that refutes your message, as is the case again this time.

The ergonomics of a device are (or should be) designed by utility alone.

The size of the components are designed to be the "perfect" size for the end user not the perfect size for the display manufacturer. To alter the device's ergonomics for reasons of economics is the exact wrong way to go about designing a product and one of the main reasons why other designed from other companies often fail.

I've been wrong a half-dozen times here, and admitted to every one of them AFAIK. It's not terribly frequent nor do I post half-truths. As for knowing Apple's pricing policies that's a big assumption. I would pay attention to that only if I commonly purchased or considered purchasing iPads. I would guess even most who had bought iPads weren't aware Apple always priced that way. We all probably missed the announcement.

Trollish behavior would include "childish commenters who deploy inflammatory and boorish antics". There's also an egregious troll who according to ArsTechnica is "Any troll that personally attacks someone else in our community. If you're not bright enough to criticize ideas without personally criticizing individuals, we're not interested in having you around. If a user chooses to venture into the territory of trolling others, it is their fault and their fault alone for what happens to them next. We will not weep for trolls, nor will we feel any remorse."

I do my utmost to be respectful to even those with trollish behavior(!), just as I avoided responding in kind to you. The forums would be better off if we all did.

No, you are very condescending, passive aggressive attacks on others, being contrary just to argue and not really helping move the discussion. Although I am impressed by your copy and paste skills, which you cherry pick. Must be a slow day running all your businesses and being a graphic artist, to troll these boards all the time.

So if these displays are harder to manufacture, will they have more bad pixels? I am guessing they will.

How noticeable will a single bad pixel at this resolution be?

I wonder what Apple's acceptable rate for defective pixels is?

Let us have a moment of silence for AMOLED/Pentile (the way to make specs state higher resolution than is really delivered... because each pixel isnt even a full pixel):

(The one on the left isnt a retina display, but its sure better than the Pentile!)

All things being equal there are 4x as many pixels so if the percentages stay the same you'll have 4x as many. That said, i don't know of anyone having a problem with this on the iPhone 4/4S which have 106,276px per sq inch compared to the iPad 3's 70,225px per sq inch.

Why buy it from BB if you've got an Apple Store two blocks away? Reward Zone points? Is $5 worth of points worth the pain of shopping there?
