iPad: IGZO Screen question

[LancD]

I just got the ipad 4 and now have heard about Igzo. How much better of a resolution will it be? Is it going to be a dramatic difference over the current retina display which is 326 ppi I believe? Yes, the ppi will be better but how much will the human eye be able to detect this? Thanks!

I think IGZO can provide something like 500ppi which is almost double that of retina.

The biggest advantage however,is that it uses far less power so that mobile devices can be made lighter and thinner due to the much smaller batteries required.

I've heard that beyond 300 ppi the human eye can't notice differences, so...

This.

I can't wait for IGZO screens, the extra battery life will be awesome.

don't get your hopes up. the battery will probably be thinner/smaller, so it will likely have the same life as it has now.

I surely miss the sting in your posts and reply ! especially when iPad-3 was launched, and Boy Then You were Mighty Pissed off with One Mr.Tim Cook and Apple as a Company lol This was over the screen issues you had !

Man ! I miss it !

That's what I was thinking. But one can still hope.

I'm reasonably sure that when/if Apple switches to IGZO displays, there won't be any increased battery life. Apple will more than likely leverage those power savings into smaller batteries for thinner and lighter devices.

That is only part of the story. It depends on the distance as well. Whether you can distinguish the pixels, whether it increases perceived resolution, are dependent on two things, PPI and distance together.

That second variable is of paramount importance. If you hold an iPad mini closer to your face than an iPad because the screen is smaller, then PPI is somewhat offset by the shorter distance, implying it needs a higher PPI to have an equivalent perceived effect, which makes the single measurement of PPI mostly not very useful except in direct comparison with screens that are the same size and that are viewed at the same distance.

The real question is what can the human vision system resolve? The answer is 1/60th of a degree of arc, for 20/20 vision. You have to factor in both PPI and distance to get the true answer of whether the PPI and distance together put that under, or over, that resolution perception threshold. Over, we can distinguish individual pixels; under, we can't. But PPI alone can't answer that.

You can't even tell the pixels currently... IGZO screen are for battery life. And much better battery life.

Igzo LCD is just a display technology like conventional LCD is. It uses less energy and has the ability to have more pixels crammed into the same amount of space compared to conventional LCD. The actual amount of pixels a certain device will have is determined by the manufacturer. It opens up more possibilities for manufacturers though. Retina is simply the name apple gives to a device that has 4 times the number of pixels to their non retina counterpart. It's not a display technology. It's like HD, that's also just a name given to a device that has a 1920x1080 resolution. It's not related to the display technology so you can get plasma HD TVs, LED HD TVs etc.

IGZO is at least three and probably more like nine months away.

Like you, I am eagerly anticipating its release.

In the mean time, just enjoy your iPad 4. It is a wonderful device.

As for the exact timeframe, analysts can make predictions. So why can't I?

The fact is that IGZO technology is available. If Apple doesn't make use of it, someone else will.

I do not agree with that

Apple won't change the resolution again. The only way the ppi will increase is if the screen size decreases.

Will the picture not look any better? Will the picture quality be pretty close to the same as the current retina display?

It may have better colour saturation.

The jump from regular to Retina is quite noticible, the jump from Retina to that higher ppi won't be. But by keeping the same resolution, the only way to get a higher ppi is by decreasing the screen size. This will happen when the Mini gets Retina.

[smileyface]

I think if you double the resolution of retina,there will be a difference but I agree beyond 300 ppi the law of diminishing return starts to kick in.

You may not be able to see pixels beyond 330 ppi but pictures and videos will look more etched and real.

As far as we know, igzo panels haven't yet been mass produced on a global scale. Only recently, they've been mass produced for Japan only.

From Wikipedia...."Sharp announced in mid-April 2012 that they were producing bulk volumes of 32-inch 3840×2160, 10-inch 2560×1600 and 7-inch 1280x800 IGZO panels."

They are a bit more expensive than normal lcd's so it remains to be seen if Apple introduces them in March.

Yes, but not on a global scale. Igzo panels are difficult to produce and mass production in very expensive.

Just to clear up the confusion. Retina is a rather diffuse term. iPad 3 and 4 has 264 PPI, compared to 326 PPI on the iPhone/iPods.
