iPod touch OLED screen in the 3rd gen Touch...

This image should shed some light on OLED power consumption compared to LCDs:

Notice how the LCD consumes the same amount of power regardless of the image being displayed, while there's a significant variation in OLED power consumption, going as far as consuming 330% more power than LCDs when displaying a white image.

This is why the Zune HD has white-on-black text rather than black-on-white text, to go around OLED`s shortcommings.

OLED is actually worse battery life when the screen is white. Thus, it's suited to white-on-black user interfaces (read: Zune), which is the less common theme on the iPhone OS.

EDIT: and that's what I get for not looking at page 2 :p

Thats because the backlighting on the LCD display has to always be on while in use and draws a consistant amount of power all the time.

You'll notice short of going for a consistant bright white screen OLED on average uses less power for regular images and video. Theres very few applications where an OLED screen will overall consume more power then its LCD counterpart. Unless you set your screen to blank bright white and you want to use it as a flashlight or something I can't see a disadvantage.

That's true.

Most websites have black-on-white text. So when you're browsing the web on an OLED display, you might end up consuming more power. Zune HD does have a web browser, so it's interesting to see how it'll stack up against an iPhone/iPod touch.

Can be solved by having the browser lower the intensity of the solid white background on websites by 50% same could be done for any office apps or anything else thats uses a flat white background. Media could be left to default white levels and won't be affected.

Its the bright white thats the problem, not the white itself.

no doubt ;)

Lancing, what do you think... Are we getting one in September? Or do you think OLED will debut in the next iPhone update?

...we have NOT seen any leak of info about OLED purchasing from Apple :(
 
re

Not sure if we will see it in September but it is definitely something Apple need to look at. I get about 3:00/3:30 video playback with wifi off and brightness low. An OLED would be awesome
 
Follow the money!!!

Come on guys I say this every time apple is about to announce a new product.

If apple adds an OLED screen to the ipod will they still be able to maintain a 150% markup in profit from the hardware? The answer is no. Apple upgrades according to profit margin plain and simple. We will see no OLED in the ipod touch till it comes down in price. The iphone and ipod have to share hardware in order to keep cost down for apple. This is the reason they maintain very few products and use the same parts for the entire lineup. Think about guys. The new ipod touch will have everything the same as the iphone 3GS minus the cell phone component. Just like before.
 
I don't know if this has been mentioned here yet, but the iPod 2G was significantly faster than its counterpart iPhone, due to its newer processor. So Apple is willing to put stuff into the iPod touch before iPhone. Case #2: Nike+ sensor. I don't think the iPhone 3Gs has one (not entirely sure though).

And, as for the OLED screen, looks like pretty good power savings most of the time to me. Remember that the screen is the most power hungry part of the device, so any savings there are significant.

Personally I doubt it given theres been no buzz about it even being a possibility.

However competition will likey force Apple to adopt OLED in the 4G next year.

The iPhone 3GS has Nike+ built-in. But the iPhone 3G didn't when the second generation iPod Touch was announced. Apple seems to be trying a few things out on the iPod Touch before putting them over to the iPhone. That's why I think the next generation of the iPod Touch could include an OLED display, which will later come to the iPhone. And price probably won't be an issue when you look at the Zune HD's prices.
