Techs & Trends
Thought the led would be a great feature on the phones. Sounds like maybe not.
Have to actually go look at one someday.
There's no 'screen door' effect. The display is absolutely gorgeous.
The "Retina" display in the iPhone 4 has the highest pixel density of any mobile display at the moment, so anything else is going to seem a bit less crisp, or have a "screen door effect" if you look really closely.
But compared to most phone displays, the OLED displays on the Galaxy S series, etc. (like the Captivate or Focus) are considered very good and compare favorably an LCD of similar size and resolution.
Are these things you can see at 1-2 feet away (normal use) or just when you hold it up to your eye? I would argue that unless it bothers you from a distance of 18 inches, it's a non-issue.
Some of them do "cheat" a bit with sub-pixels. The Nexus One OLED screen is one infamous example of this. It did not have all three colors (red green and blue) for each advertised "pixel" making up the "full" resolution. This did affect the image quality and make it look as you describe. It annoyed me, although it doesn't seem to annoy most people.
But I haven't heard this complaint about any of the recent Samsung sAMOLED phones.
I don't use a samsung AMOLED personally, so I can't really compare it directly, but when handling them, they also seem "fuzzy" compared to an LCD screen.
But like I said, the effect is so minor I only notice it when I'm using both devices, which most customers won't.
And Menno pretty much described exactly how I feel about them.
Since this conversation, I've been looking more closely for this, and noticing it more here at CES.
As I said before, it's an issue of sub-pixels. It can happen with both LCD and OLED, I believe. The issue isn't inherent in OLED technology, it's just that some popular OLED panels have an unusual sub-pixel arrangement that sort of cheats to get the stated resolution.
What I mean is that... on a normal display, each pixel has red, green and blue. On the screens where you're noticing this issue, there are only two colors per pixel. One pixel might have blue and green, while the next pixel has red and blue, for example. This leads to the less-smooth appearance of straight lines that you're ...

That water under the bridge, I do own and use a Galaxy S as my daily driver. It looks great indoors, as long as the image I'm looking at is less than 15% white.
The greens aren't quite as terrible on teh Super AMOLED, but the whites are actually just really intense blues pretending to be white.
Right now, it looks like us consumers get to choose between good whites (LCD) or good blacks (AMOLED), but nothing mass-market really knocks them both out of the park. Yet.
The Galaxy S series of phones, Motorola Droid (milestone), and several other phones have the real Gorilla Glass by Cornings. If you go to cornings website, they have a complete list of phones/devices using the stuff.
That said, just like the iPhone, most smart phones have a version of Gorilla glass anymore, some are better than others, with Gorilla Glass being the gold standard.
Basically, like Rich said, it is chemically hardened through a process of heat cycles and then quenching it with specific chemicals, as well during the initial processing they incorporate certain chemicals and mi...
I think the contrast ratio numbers can be deceptive to those bad at math (most of us.) It's important to check these things out in person. Looking purely at the numbers, some might think the 50:000:1 ratio is 60x better. It's not. On a scale of grey, with 0 being true black and 1,000 being true white, we're talking about the difference between 1 and 2. Most people wi...
The Super AMOLED screen is supposed to be one of the best screens out on the market today. I can't see how you would see pixels on the screen.
The 4 inch Super-Amoled Display has a WVGA resolution and 16 million colours.
You can't go wrong with 16 million colours.
