Here's how Apple squeezed over 3 million pixels in the new iPad screen
The new, third iPad comes with a stunning Retina display with a resolution of 2048x1536 pixels - that’s 264ppi, or four times the number of pixels of older iPads. What you may not know is that it wasn’t Apple who created the technology making such a leap possible. It was actually engineers from Sharp and JSR that pioneered a design called Super High Aperture (SHA) years ago.

Due to various reasons including some issues with the complex process of designing such high-res displays, it didn’t get traction when it was first unveiled. Now, however it’s getting more and more popular, and might soon become the standard for LCD displays.

Apple explains SHA by simply saying that pixels are elevated and thus separated from the signals.

Now, getting a bit more technical, you’d see that SHA increases the aperture ratio using a 3µm thick photo-definable acrylic resin layer to divide the device in planes and allow for a larger vertical gap between pixel electrodes and signal lines. Why? This makes it possible to avoid cross talk and decrease capacitive coupling. All of the pros and cons of the SHA method are illustrated below.

It seems that this translates into least double the number of LEDs used which confirms the much larger battery used in the new iPad. Hit the source link below for all the fine technical details.

the screen is sick but the battery life double the leds which means battery life if battery life increases then so will the use of this

I love how the article states "here's how apple"...

heres how apple did it. they called up sharp and said "hey, can we get some exclusive lovin on that screen? yea? ok, thanks, we will put it in the new ipad"
end of day.

apple doesnt MAKE anything, they are just a software vendor.

I know, Apple’s recipe for success is to ask the vendors can you make this, & can you make that. Then you get authors who know better (supposedly) and make headlines like "Here's how Apple squeezed over 3 million pixels in the new iPad screen". How wrong is that headline?

Thus adding to the huge list of how Apple has the media wrapped around their fingers. Would it have been so hard to say the truth like "Here's how Sharp squeezed over 3 million pixels in the new iPad screen".

Apple has done NOTHING but buy the screens. They only develop the OS & maybe how they want their products to look. That’s about it. (Unless you call the manipulation of Victor H. or media as an Apple goal to be done.)

Food for thought!

came here to say that..

why not give Sharp/JSR the credits due in the TITLE and not merely in the article, down at the third sentence (or the last sentence in the first paragraph)?

Well, from everything I have read, they design the chips and displays and outsource them for production. This is also the reason why they can choose 1 or more vendor or cut a vendor for producing those particular items. They don't have to actually produce anything. They designed it so it is theirs no?

they design it.. but still manufacturers are the ones who manage to pull it off.. so not much credits for apple..

i can design a phone that can read my mind, thus eliminating the need of touch screen or buttons.. but will i get the credit for actually making it if i ask let's say Asus to make it?

HTC has just released quad core phone, but the credit still goes to Nvidia for making that Tegra 3..

Why should HTC get any credit? They did not design the chip so why should they take credit? They are just a purchaser of a common market chip. The A5X and Retina Display are not common market items as they were designed by that said company. Its great that Sharp assembled it for them but their are many other companies who would salivate at getting that contract. The tech specs were created and designed by Apple so it is their rightful place to take credit for that feat.

What do you mean "Apple squeezed over 3 million pixels" in the headline ? It is the panel/display maker (Sharp/JSR) who did that. All Apple does is squeeze the suppliers for lowest cost and highest specs. Then they fleece the consumers with outrageous prices. Disgusting...

Obviously, as its the duty of apple, to test the product before release. Such a huge demand(pressure, actually.) from apple, beyond the limit of sharp's production capability, naturally it will be prone to defects. Apple has to take the blame.

but if it succeed is Sharp.. hmmm ok got it...so only when it fails is Apple.. just trying to digest this

ps. even if tested things do fail . specially electronics components

because it is their design.. if they give crappy spec sheets to be built, they the manufacturer can simply say they were asked by apple to make those.. but if apple ask for something that has never been done before, of course they will be given the credit, it is because they have done what apple asked, something that has never been done before..

it's like, Sharp can give 400ppi display, but apple only wants 150ppi.. so guess who's the stupid?

and if there has never been a 9" screen with a 260ppi before, and apple has given the task to manufacture that to Sharp, and Sharp actually pulls it off.. the achievement is on Sharp, as they are the one who actually made it..

and yes, tested things do fail, especially electronics, but not all will fail, only a handful of lemons, if all fails, then there must be something wrong with the QC, which is done ultimately by apple in the end..

take antennae gate for example.. the components don't actually fail, it is Apple's design that fails.. the majority of iPhone 4 shipped had the problem, antennae manufacturer's fault or apple's fault? i think it's the latter, cus after they updated the OS, it is gone, so it's actually a working component, but apple's design rendered it almost useless in certain grips..

take WiFi issues with some HTC 2011 models, the components are working, but HTC's design that makes them fail..

iPhone 4/4S screen being brittle, it's not OEM's fault, apple know that the glass is not as strong as Gorilla Glass, but they still went ahead with that.. who's fault? Apple for not choosing the better one when they can.. and now they realised their fault, they have the Gorilla Glass in the new iPad..

you just can't see that..
your sarcasm level : fail..

There is a couple of flaws in your post.
#1 you assume sharp can pull off lets say a 400 ppi and apple only asks for a 150ppi display. How do you know it wasn't the other way around apple asks for a 400 ppi display and sharp can only do 150. Thats not apple's fault its sharp so if you are going to give sharp 100 percent credit for its good compenets in apple products well then you have to give them credit for the bad ones aswell.
#2 the iphone 4 has gorrila glass confirmed by apple in the jobs report. I drop mine all the time not a scratch.
#3 attengate was solved by new attena not by software update. Not to mention it was never much of anything to begin with.

You're stupid beyond belief aren't you. Apple will get blamed because they had the final certification on whether to let the device go to market. So if the screen fails of course you will go to Apple about it jackass. That's like your Ford having engine failure and you traveling to Germany to complain to the engine builder...stupid!

Blind apple devotee you definitely are, which is why the phone built for iDiots works perfectly for you...you might cock something up fierce considering how strange your logic is.

When did Apple create anything? They do not build a damn thing but software, and they bolt on parts to create their devices. Smart company to have so many idiots out there believe they actually create anything.
