Like stated before, viewing angles are not big of an issue in small screens. I care about screen quality the most, and unfortunetly TN panel will not give such colorful and vivid bright colors and pure true blacks as IPS screen in iPhone4. Quality-wise, screen in iPod touch 4gen is the same as those in 2/3gen, it's got only higher resolution, but quality is the same.

See. Maybe it's me, but when I see black on a display, of any type - Macbook, iPad, iPhone, (*random other manufacturer), etc., I have NEVER noticed that "Hey, this black looks terrible". And I doubt that 99% of people will ever care. Come on, this is a moot point.
 
24bits of color is something impossible to achieve in TN panels. TN matrix is physically capable of only 6bit colors at most. That's one of many reasons for being poor picture quality.

That is interesting, because in the keynote, one of the things listed under the Retina Display while he was talking about the iPod touch was that it had 24-bit color.

The thing that is cut off is LED, for LED backlit.
 
Wikipedia's specs are wrong and they will be corrected. They simply copied iPhone's 4 screen specs, and the iPhone's LCD is different, as we all have discovered so far.

when they say 6-bit, they mean 6-bits per channel. RGB and an Alpha channel. 6*4=24-bit. IPS displays are usually 8-bit per channel

Come on, let the people pimp their iPads and iPhone 4's (and perhaps Zune HD's, remember those?) and worry their knitted brows over nothing.
 
Aside from A4 chip and maybe face-time camera, there's really no improvements worth upgrading from iPod touch 3rd generation.

Alright, let me follow your logic here...

TN panel is a joke

No, it isn't. It is still MUCH better than the current iPod Touch line. The $229 device doesn't NEED an IPS display.

0,7mpix rear camera is a joke.

Its much better than a $229 device without a camera, isn't it?

My point is, 4th gen touch is the first touch that doesn't follow "it's an iPhone without a phone" scheme.

Who said it was supposed to? The price difference between the iPod Touch and the iPhone is HUGE. It isn't supposed to just be an iPhone without a phone.

iPod touch 1st, 2nd and 3rd generations were all identical copies of an iPhones, only without GSM module and camera.

No. The iPod Touch 1st gen had NO speaker, NO volume rocker, NO bluetooth, and NO microphone. Major difference.

Touch 3rd gen was even slightly speedier than 3gs. iPod touch 4th gen is the first iPod in touch family with many more cuts in cost production compared to iPhone4. It's very very sad that Apple started behaving like this.

Cuts? They added 2 cameras, a much better screen, gyroscope, and more and thats a cut? Wow...

Exactly, thanks for saying this! :)
Those new features would be great improvement, if they were like those in the iPhone4. Sad thing is, they're simply not... Worse screen, worse camera. I would not be surprised if there won't be 512mb of ram in the new touch, but it's yet to be confirmed, since it's still a gossip. And I'm waiting for an iFixit teardown to find out what else is inferior compared to the newest iPhone.

So you mean to tell me, and please confirm my thoughts, that a $229 device should have IDENTICAL components as a $600 device sans a GSM module? Seriously? Do you realize how absolutely stupid your reasoning is?? Are you trying to tell me that a GSM module justifies a $370 price increase? You're out of touch with reality buddy.
 
24-bit pretty much confirms that it's a TN panel. IPS is 32-bit. The sensors on digital SLRs range from 48-bit to 56-bit.
And you will not see any difference on a 3.5" 960x640 Retina display from either the iPod Touch 4G or iPhone 4 when viewed at a normal angle.

There won't be a different in color shift at a normal viewing angle, but the absolute picture quality will be different. One of the first things I noticed with the iPhone 4 (besides the resolution) was that the colors were much more pleasing to the eye, and the blacks were significantly blacker. Those qualities are inherent to the IPS technology.

32-bit colors offers a much better dynamic range compared to 24-bit... This will be especially noticeable on images that utilize gradients.

edit: I may be wrong and in which case 24-bit means 8-bit panel and not TN. But then I have no idea where 16 and 32 bit panels come from since neither are divisible by 3.

IPS screen technology are characterized by much wider viewing angles, so the screen in new touch can't be IPS. You can clearly see wider off-axis viewing in an iPhone4, colors don't shift like on iPod touch screen.

No one is going to be playing games or emailing someone at that angle. I'm perfectly ok with the display because:
1. It's better than the previous iPod touch displays.
2. No one holds it like that picture above.
3. The standard buyer doesn't really know the difference between IPS and TN, just about pixel density.
4. The new iPod touch still costs only $229.

Get over yourselves people. Possibly thank Apple for adding the Retina Display?
 
I think the viewing angle is bothering so many people is b/c they want to watch a movie on their iPT while laying in bed w/ the touch resting on their belly - this way they can hold a sandwich in one hand and a drink in the other...what the hell you can do it w/ the new iPhone...:rolleyes:

Not necessarily, if you consider there are 3 colors.. "RGB" and he said 24-bit color so thats 8-bits a color.. if you include alpha, it could mean 32-bit which is the same as IPS :p
 
I don't mean to sound like a clueless idiot, but how do we know the iPhone 4 IPS screen is 32bit?

I went poking around on the internet looking up information about the iPhone 4 IPS screen and I came across this:

Color Depth

Color depth refers to the resolution of color supported by both the display hardware and the operating system software. Of the screens tested, only iPhone 4 and the Motorola Droid X supply screens capable of 24-bit color (16,777,216 colors, which Apple calls "millions" and which Windows refers to a "true color"); HTC's hardware on the Incredible and EVO can only display 16-bit color (65,535 colors, which Apple calls "thousands" and which Windows refers to a "high color").

In their bundled software however, only the iPhone 4 actually displays 24-bit color. Android's photo application is crippled to only support 16-bit color, reducing the Motorola Droid X to the same performance as the Incredible and EVO, expressing color banding and jaggies due to their significantly lower color resolution.

I personally don't see why there is a 5+ page thread on this..my iPad has IPS and I didn't even know tell I read this thread. I compared my iPad with my touch and it really doesn't seam that different....and it will be worth the price given it has retina display and two cameras among it's cool new features.

It's a bragging right thing. An issue of huge importance for many geeks and online forum dwellers like many of us. ;)

For large monitors it's much more important because viewing angles of many TNs are bad enough that color uniformity across the screen isn't there. Such problem doesn't apply to smaller screens though.
 
when they say 6-bit, they mean 6-bits per channel. RGB and an Alpha channel. 6*4=24-bit. IPS displays are usually 8-bit per channel

The alpha channel counts only in software... there's no such thing as an alpha channel in hardware. There are 3 colors - red, green, blue. 6 bits = 64 shades that can be displayed of each color.. 6 * 3 = 18 bits in all.

8 bit color, 256 shades of each = 24 bit screen. Ergo, it is likely IPS.

How about MVA or PVA. Both of these are 24 bit as well.

Again, you forgot the situation with iPod 3rd gen vs iPhone 3GS. Yes, GSM & camera modules justified nearly a 400$ difference. Now, all of a sudden you're acting like it never happened... I don't care what needs to be to justify whatever price gap you imagine. Apple itself taught us it only need to be GSM module and a camera. Blame Apple for their policy over the last 3 years, and stop acting like you were unaware of this. So-called "retina display" is only Apple's marketing bs, in reality it's just a regular IPS screen with higher resolution, that's it. It's production cost is 10-20$ more than TN matrix, so I see no reason why it wasn't implemented to iPod touch 4gen.

Who said it was supposed to? The price difference between the iPod Touch and the iPhone is HUGE. It isn't supposed to just be an iPhone without a phone.
Steve Jobs, at the last Apple's event on September the 1st. Blame him, blame Apple's policy for not following your logic...

What makes you think it's a better screen than let's say in touch 3rd gen? Higher resolution doesn't automatically mean better quality. If the technology is poor (and TN is the worst), not much can be done to actually improve PQ. You will not be able do distinguish pixels, but colors will be still dull and washed out, not to mention non-existing blacks, compared to IPS. Maybe you don't care about PQ in mobile devices, but the market has moved forward. There's a huge demand for Samsung's AMOLED screens for mobile devices right now. Same with TVs - OLED is the future. So yeah, people definetly care and demand better screens. An iPod touch is all about the screen, which is the biggest and the most important part in it, so to me it's PQ is very important.
