Super AMOLED

Anand talked about the Galaxy S line's Super AMOLED display in his Epic 4G review. I thought I'd expand on that by saying that reducing the number of layers and air gaps between display, coating, capacitive digitizer, and finally top layer glass, is what the "Super" in Super AMOLED is all about.

It might not sound like a big deal, but reducing the number of interfaces between those light emitting OLED pixels and your eye is hugely important. Each successive interface - purely by being an interface with different index of refraction - creates a reflection that attenuates light. Glass to air interfaces usually have a reflection coefficient of around 4%, meaning only 96% of light makes it through. If you've got two or more air-glass interfaces, that adds up quickly, and you lose that light entirely to reflection. How much that reflection coefficient is depends on the index of materials at the interface, but more interfaces in general hurts transmission. Reflections and glare is also what makes reading displays difficult outside. 

This sort of display-digitizer lamination is quickly becoming the norm rather than the exception. The iPhone 4 did it, and now Samsung is doing it with its own AMOLED displays - expect to see others do the same. The result is that there's perceptibly less distance between the top of the digitizer and the pixels themselves (viewed from an angle), and now less glare and more light making it through. Yay for optical contact!

Next to the Nexus One, you can really see how much less distance there is between pixels and the surface of the top glass. The Samsung's Super AMOLED display literally appears to be on the surface.

The front of the Fascinate is one unbroken glass surface. Honestly, the display is probably the best part of the Fascinate. The 4" size isn't too big, but just right. At the bottom are capacitive buttons - as usual in yet a different order than I'm used to. Menu at the far left, home, back, then search from left to right.

The buttons are backlit, but only for a few seconds at a time. It's a bit frustrating, especially since right when you want them to be backlit most, they're inexplicably not lit.

I'd say AMOLED has come a long way since the Nexus One. My Nexus One routinely has ghosting and appears off-white - the Fascinate's Super AMOLED display is perfect. I used to be turned off by AMOLED's weird grain from the PenTile matrix - the Fascinate somehow has noticeably less. Either that, or I've just grown more accustomed to it. The oversaturation downside is still there, it's especially obvious when you pull screenshots from the Fascinate or any AMOLED device down to the desktop on a calibrated display.

Outside readability in practice is improved from the Nexus One. Honestly, it's still hard to read in direct sunlight outside, but it's better. For doing just about anything, seek shade.

Viewing angles on Super AMOLED are pretty awesome. I'd say contrast is pretty much unchanged even at extreme angles like 85 degrees. I've included lots of different angles and more outdoor and indoor comparison shots in the gallery below. 

The oddest parts of the Fascinate's display are all the brightness settings. There are three of them - one in settings that every Android device has, another down below that's basically dynamic contrast, and one in the browser. It can get a bit confusing controlling everything that's going on brightness wise.

I measured a bit more brightness than Anand did on the Epic 4G:

        

Black levels are perfect again, and thus so is contrast.

I have to agree with Anand - if resolution is what you care about, the iPhone 4 leads. If contrast and seriously vibrant (to the point of being oversaturated) colors are what you like, Super AMOLED is where it's at.

    The A4 in the iPhone 4 is underclocked to ~800MHz. CPU performance vs. the iPad confirms this.

    Looks like a fine cellphone. But I still have one concern since I never used a SAMSUNG product before. Does the SAMSUNG company offer a platform like iTunes Store for people to download the free apps like those on iFunia? If that was not true, I would not think its a vrey smart move to buy it regardless of its gorgeous appearance.

    Android Market... ?

    I'm so happy with my new unlocked cell phones! This has an unbelievably fast processor, great feel and easy to text on. I used to own a unlocked htc phones, but I'm so much happier with my brand new unlocked samsung phones. This Samsung Fascinate is so much better for my business and pulls my email in so much faster. And I really couldn't be happier with it since it is an unlocked verizon phones and it's a unlocked 3g phones I can take it overseas. My family loves my new phone and can't get enough of the games. I'm going to purchase another one for my son for his birthday from gsmauthority.com. Definitely would recommend this phone.

    Great review!

    Still, as it is admitted, having phones running 2.1 compared to 2.2 tends to bias the results a bit.
    What would be nice is to have enough results to set up a data base and compare phones performance by selecting common criteria (such as OS, ROMs)
    For example, I found this site that does just that with Caffeinemark benchmark :

    http://www.flexycore.com/benchmark-database-access...

    This company also has a product aimed at improving the performance of android phones (droidbooster), and set up this base so that one can see the benefit of it. But it's already a great kind of tools to compare ROMs for example.

    I did not like the way the camera comparison was conducted. The images were taken at different time of the day and in many of the images the subject wasn't even the same. How do you expect anyone to compare the quality of the images when the subject and lighting are so different?

    I just recently acquired a Samsung Vibrant (since T-Mobile is my service provider), and this phone is pretty great. I went and flashed Bionix 1.9 with Jac's OC/UV/Voodoo kernel and this thing practically *flies...*

    ... but I'm annoyed.

    Verizon got the LED flash.

    :(

    Seriously, smartphone makers. Stop making phones without an LED flash on the camera.

    I just purchased the Samsung Fascinate from Verizon but am concerned with the amount of RAM since it appears that the future version of Android (3.0) will require a minimum of 512mb of RAM to operate.

    On most sites, it states that the Fascinate phone has 512mb of RAM. However, when I go into the properties on the phone it displays only 325mb for the total.

    What is the real total memory for the Fascinate? Samsung on the galaxy comparison page hides the Fascinates memory specs however it displays them for the Epic 4G and Captivate phones. So I am not sure if it really has 512mb of RAM, or if it's pre-allocated to the operating system or if it's a unified architecture where the GPU shares the memory. Can someone please clarify?

    Also, how does this compare with the Droid X?

    Please help!

    Galaxy S as a SAMSUNG star phone in 2010, the high point is the AMOLED. Now SAMSUNG is the only company who fabricate AMOLED. For more information in website: www.mobilegoing.com
