Apple rumored to revise backlight for iPad update

post #1 of 28
Thread Starter 
On the heels of a rumor that Apple is readying a minor update of the iPad ahead of the holiday season, an unverified report from the same publication claims that Apple is interested in returning to a one-LED backlight module solution instead of the two-LED design used in the current iPad.

DigiTimes claimed on Friday that Apple was making the revisions to reduce the heat output of the iPad.

"The extra LED is reportedly adding to overheating and that using one LED will help solve overheating issues since more backlights along with more power to heat those backlights is causing overheating," the report read.

The publication's sources said that switching back to the one LED module would not affect "luminosity and clarity" of the iPad display.

Separate reports also out of the Far East have claimed that Apple will include IGZO technology from Sharp in the next iPad. The iPad maker was rumored to go with an IGZO display for its third-generation tablet, but Sharp was reportedly unable to produce sufficient volumes in time. IGZO displays are expected to allow for a thinner design with better battery life.



DigiTimes claimed on Thursday that Apple would release an iPad with "small revisions" before the end of the year. The earlier report suggested that Apple would change the battery to avoid overheating problems and also enlarge the lens hole on the device.

Shortly after Apple's latest iPad was released, some reviews claimed the device ran noticeably hotter than its predecessor. Apple, however, insisted that the tablet was operating "well within" its thermal specifications.

So when will we be able to download this?

That explains a considerable amount.

Yeah but didn't they say the same thing last year and it never happened? That apple was going to release a revise new iPad for the up coming holidays.

I still call BS on this. Meaning the heat issue. I couldn't notice it during the winter (march), and I can't notice it now in July sitting on the deck.

It still hasn't even shut down on me in the sun like my original iPad used to do.

As my friends would say "I'll flag that!" ...meaning prove it.

And the winner for most retarded statement of the day is:

Amazing how my iPad that I've owned since launch day has never 'overheated', nor that of anyone I know, contrary to sensationalist internet reports that this is a normal occurrence and a glaring hardware issue. Also incredible how spoiled we are, that when a device a few mm thin with a 10" screen pushing massively more pixels than a 1080P TV with buttery smoothness and capable of complex 3D graphics  gets warm, we start shrieking.

That's why this claim is BS. I play games and watch videos for hours on mine and the aluminum never gets warm.

Will this change increase Apple's gross profit?
post #10 of 28

Of course it will.  Apple is constantly improving it's designs.  The first HiDPI iPad screen requires two backlights.  Two back lights generate more heat than one.  Two backlights require more energy than one.  Apple will work to get back down to one to make the iPad battery life longer or make it thinner.  This is called design optimization.  It occurs for every product Apple makes. 

 

It's perfectly logical.

No, Apple is going to bring out a revised click wheel iPod.

LEDs get hot?

post #13 of 28

That would have been my first response too a couple months ago. I've replaced a half dozen standard bulbs in our home lighting with LED's since then. While the "bulb" portion itself feels barely warm in use, the base does get somewhat hot on at least the table lamps.

Apple needs to look to technology that will reduce weight and of course heat. Battery life is a factor as well. 

 

Yet, it's not likely that Apple would take a product that is selling fabulously well, as is, and make changes partway through the model run. Changes will probably happen early next year when the company unveils the next iPad (aka the iPad 4). 

 

Lighter, cooler (in more ways than one), with either better battery life or a lighter battery that contributes even more to Item A.

Not even close to as good as science fiction. Science fiction is entertaining.

Well, if you own the world supply of iPads, release it. If you're not, how does it prove that others don't have the problem?

 

Note that mine works just fine. It was really hot yesterday after several hours of reading PDFs in iBooks, but the weather was quite hot so I imagine it's quite normal.

Social Capitalist, dreamer and wise enough to know I'm never going to grow up anyway... so not trying anymore.

I just wish there was a way to add a source of a Rumor to the ignore list! I'd add 'DigiTimes' in a heart beat.

Exactly ... and let's list the things that are 100% efficient in the universe .... Oh I know maybe the Higgs bosons ... /smile

If there is any slight truth to this rumor it's maybe data concerning supplies for a less expensive iPad that isn't Retina for education discounts as an example market.

And the year before.

Of course this single backlight iPad is just the iPad mini, which is so small it only needs one anyway.

Meanwhile, Apple being Apple they are hard t work on a new single backlight that is 4 times better than the current two light system, including allowing outdoor use, and needs only half the battery of the current system. We will see it, along with the ten times stronger and one third the glare new glass on the new new iPad next spring (10 inch size spurring again the 7 inch in the fall rumor)

Frankly I think that 💩 needs to be a rating button for articles. Cause this one would earn the golden 💩💩💩 in a flash just based on Digitimes being the source. Now we just need Shaw Wu and Brian White to confirm it so it can go 💩💩💩💩💩💩💩💩💩💩

Well you don't put that tv in your lap where it could melt off your nuts.

That said, the only time mine gets more than warm is when I charge it, leave the screen on, play video or a combo. Or I leave it in the car in the sun, especially in the desert.

And if this new backlight means we might see 'real' 3d (with the same smoothness) on the iPad I'm all for it. As long as its glasses free cause 3d glasses are an uncomfortable mess. But I doubt it will, this round. They will go retina, high refresh on the iMacs etc and get content in the iTunes store first. But I suspect around the new new new new iPad we'll see something like that

BS. ... There is no overheating problem.

And no way apple will change anything..,

Maybe iPad 4 will have some of the changes.

LOL, the AppleInsider homepage would have two posts and the forum would look like a ghost town.

 

But heck, that's a wonderful idea. It would definitely improve the signal-to-noise ratio around here!

 

:-)

 

Actually, it's more realistic to look at AppleInsider, MacRumors, etc. as science fiction blogs here in 2012. The rumor quality has degraded so much and the amount of commentary by people who have a very tenuous grasp on reality has skyrocketed. If you look at it that way, this site is far more entertaining than Battlestar Galactica, Serenity, whatever.

The batteries and circuitry that power them certainly do.

There's a difference between generate heat and get hot. The current iPad gets a little bit warm, but if that bothers someone, then they've probably never owned a notebook computer, many are uncomfortable through jeans on a winter night. I've never had my iPad get anywhere nearly notebook computer warm. My iPads barely get above ambient temperature, and half of that might be because of my own body heat. I don't think it can get to thermal alarm under its own power, unless something is broken or you're in the desert sun.

Geez must be a slow news day to keep quoting DigiTimes. What is the accuracy rate of their so-called informed sources ? 5% ?
 

post #28 of 28

Try running the Navigon navigation app with 3D terrain rendering. I did last weekend with my "New" iPad in a BookBook case.....it overheated, popped up the thermal warning message and automatically shutdown. There is (or can be) an overheating problem, but it can just as easily be caused by crappy software programming as it can be by Apple's hardware design.
