Digitimes reports (http://www.digitimes.com/news/a20111107PD204.html) that Apple is currently evaluating a pair of options for addressing issues with LED backlighting on the iPad 3, noting that the current backlight bar design used in the iPad 2 is insufficient for the higher-resolution display reportedly set to debut in the next-generation tablet.One of the new LED light bar designs has proposed to keep the light bar in a single-bar form factor but with two LED chips inside; the other has suggested using dual-LED light bars, the sources indicated.

Apple is likely to adopt the design using dual light bars, the sources asserted, adding that BLU makers have solved issues related heat dissipation and battery consumption for the dual light bar design.Apple is unsurprisingly expected to introduce the iPad 3 early next year, with The Wall Street Journal being the highest-profile publication to confirm that timeline (http://www.macrumors.com/2011/08/19/wall-street-journal-confirms-early-2012-ipad-3-with-retina-display/). A higher-resolution "Retina" display is the most widely-claimed enhancement scheduled for the device, although several reports have indicated that Apple's suppliers are struggling (http://www.macrumors.com/2011/10/27/lg-and-samsung-still-struggling-with-retina-ipad-3-display/) to produce the displays in volume.

By choosing a display with higher pixel density they need more light to provide the same brightness (you loose about 50% of the light as it passes through all the display elements).

Dual light bar just means there is two strips of LED lights behind the diffuser, filters and LCD.

LED Backlight is the best choice, but I guess it would decrease battery life.
One bar could cause a faded effect on the opposite end; two bars may help even out the light. I hope they do it right, otherwise the display may not have an evenly bright light.

Why have two really clever bars in there?

Surely Apple can develop one really, really, really clever bar.

Call it, like "Genius Bar" or something.

No, hang on. Think they've done that one already.

I'd be sort of surprised if apple went with a "retina" display with the iPad 3 considering there still isn't a single viable competitor tablet in the game.

[/url]

or by using 2 bars with a much lower pixel density (including perhaps the same) they might be able to produce an iPad that doesn't go practically black in sunlight and shut up the naysayers over said issue.

Frankly I haven't seen anyone really back up the need for a 300+dpi iPad so I'm thinking that Apple will either keep the same density or perhaps go slightly higher to something in the 1080-1200p range and conquer the outdoor issue first. More brightness, better sensor, perhaps major improvements on that oleo phobic coating with a touch of anti-glare tossed in. Any displays higher than that might be test units for the iPad 4, 5 or even 6. After all they don't design these things overnight.

See that's the thing it's all conjecture at the moment. There's nothing saying it will be the iPad 3. Apple may purely be sourcing information for the next edition.
Seems a bit late in the game for drastic design changes if they plan on an early 2012 release.
Main point is we just won't know till its announced. Sure we can make educated guesses, but that's all they are, guesses.

EDIT: ah Charlituna beat me to the same point I see lol.

There's only reason to pursue extra pixel density and increased luminescence in a display, and it's not just because Retina Displays look sharper. If you can drive twice the number of pixels, then you can drive the standard number of pixels PER EYE. Retina Displays are the stepping stone to glasses-free 3D.

Android tablets have caught up significantly... but a retina display would put the iPad 3 in the clear lead again.


Now if only the iPad 3 had a card slot or some sort of expansion port ...

I hope they go for a dual bar backlight.

Every time I've seen an iPad I've always thought the backlight looked awfully uneven, bright on one side and dark on the other. Most people don't seem to notice it, or it doesn't bother them, but it's what's stopping me buying one because I know it'd really bug me.

I think the main point for me though is the user experience. I won't say that a retina screen wouldn't be better, but the reason I bought the iPad is the over all experience and ease of use. if I want to get to something it's no more than a couple of clicks away. Can it be improved? Of course everything always can be. However for me personally it's the operating system that's won me over, same with OSX on the mac.
I mean look at the origional iphone and 3G/S, still fantastic phones, I just think the retina display has spoilt people, no ones happy now unless it's retina. Where as at the time the 3GS was the best thing since sliced bread.

A very large number of iPads are ending up in the hands of medical professionals, 300+ dpi would provide a level of resolution exceeding desktop monitors currently being used for diagnostics in medical imaging. There is not only a need but a demand as well. And given the likely price point (same as the current models or less) this would represent a huge win.

No one said they can't, all I'm saying is apple users seem to have gotten into the mindset that we all need a retina display.

Technology always mOves forward and as time goes by things get cheaper. I just think for the price point a retina display is too much to ask in the ipad 3.
They can't honestly increase the price any further, the iPad2 64GB + 3G is highly priced for a tablet, and for not a lot more puts it in the MBA territory.
As jobs himself stated in the keynote the iPad is meant to be a happy medium between the iphone and mac, not a replacement.

The price of a display is not given by its resolution, but by its size.

I didn't buy the iPad 2 because it doesn't have retina.

That has nothing to do with whether the next iPad could already be OLED.

So your saying that The current 1,024 x 768 display would be the same as a higher resolution display as long as there the same size?

For all we know the iPad 3 could be 3D! Unlikely I know, but the point is we just don't know untill it's announced.

A higher resolution display could initially cost a bit more because it is not common, but the main driver of a screen cost at the same technology is its size.

If Apple introduces a retina display on an iPad while retaining or even just staying close to the current price point, I would be very impressed.

To the posters saying that screen size affects price more than resolution, that's true in general, but you need to keep in mind that a retina resolution on an iPad is an extremely high resolution, especially for a screen this size. This pretty much has to have a big effect on price, although Apple's huge supply change and high volume of production and purchasing will probably help offset that.

Seriously, think about it. If the retina display ends up being double the current resolution, it'll be 2,048x1,536... and that's a lot of pixels! especially for such a small screen. Advanced technology like that is never cheap, especially when it's brand new. But, I think Apple providing retina displays on iPads is inevitable. It's just a question of when. But we can clearly see that apple has focused on improving the graphics power of all the iOS devices.... so, I wouldn't be surprised at all if the rumours of a retina display in a iPad 3 that comes out in the near future turn out to be true. And with Apple's talented engineering teams, I also wouldn't be surprised if they can do it while maintaining a good price point.

And, I have to say, I would LOVE to see a retina display on an iPad. Personally, for me, after seeing retina displays on the iPhone 4 and 4S... there's no going back to seeing "big" blocky pixels on my screen! :)

If Apple doesn't do a high/higher DPI display, then they might very well be switching to fix the flashlighting some iPads are prone to.

It would most likely still be under 300ppi. An exact doubling of the current resolution gives you 264ppi. But anyway, I'll give you a great reason to increase the pixel density: Chinese characters (and those derived from them). Take a look...

http://www.blogcdn.com/www.engadget.com/media/2011/10/toshiba-498ppi-display-2.jpg

As you can see the pixel density makes a big difference with how accurately these characters can be rendered. And given that there are thousands of these characters, that's a big deal.

If Apple releases a retina iPad 3, I will sell my iPad 2 and upgrade once again. The retina display on the iPhone 4S is such an improvement over my iPhone 3GS. I actually find I enjoy looking at the iPhone screen even though sometimes the iPad is handy... Something very soothing on the eyes with that much pixel density.

I had seen the iPhone 4 display, but never used it continually. I always thought it was beautiful, but did not realize what a difference it makes.

As a reading device, the iPad ideally needs a retina display. Try reading a magazine on it - that's not modified for iPad use directly but is a PDF reproduction of a physical magazine such as those in the Zinio app. You cannot comfortably read such magazine without zooming in all the time because small text is too blurry.

I love my iPad but in order to read the magazines that I'd like to on it in comfort (e.g. New Scientist), it needs a retina display. For this reason I'll upgrade as soon as one is released. Everything else is just fine on my iPad.

IF Apple is doing an Apple TV, they will probably make the iPad 3's screen 1080p, so that iPad apps will work with the tv at netive res, and so they don't have to have 4 copies of each element in iOS and each app.

Give me a higher resolution display and I buy an iPad or whatever other tablet can give me that. My main use for these things would be reading PDF files and even though the iPad 2 can deliver that I am not too happy with how fonts look in full page view.

I don't care much for battery life, you often use these things close to a power outlet anyway. But I do care about weight and hope they can make it less heavy in the future, too.

For all that I'm very willing to wait.
