How Samsung creates the true HD Super AMOLED screen on the Galaxy S3

by: Bams SadewoApril 11, 2012

As the world waits for the impending arrival of the Samsung Galaxy S3, more details trickle out about the flagship phone, making tech pundits pore over every little scrap of information, in a sort of virtual feeding frenzy. Coming from the same source that revealed the physical home button and 5-column layout of the phone, a new report allegedly reveales the process used to produce the true HD Super AMOLED display of the Samsung Galaxy S3.

The display on the Samsung Galaxy S3 will improve upon its predecessor — that much is a foregone conclusion. Moving away from the 4.3-inch screen of the Galaxy S2, the successor will carry a 1280 x 800 resolution, like the Galaxy Note and Galaxy Nexus, on an screen that measures at least 4.7-inch (or 4.65 according to other rumors). Many reports have that the Samsung Galaxy S3’s display will boast a 316ppi pixel density, which will be a significant improvement over the 250ppi found on the Galaxy S2.

The fact that the Galaxy Note and Galaxy Nexus come with a PenTile matrix arrangement didn’t go down well with those that demand display perfection. But Samsung, it appears, has found ways to produce a normal RGB matrix for the Samsung Galaxy S3 (without the burdening cost), by combining the Fine Metal Mask (FMM) process used in AMOLED screen production with the new Laser-Induced Thermal Imaging (LITI) method. The latter helps Samsung produce pixels as small as 2.5 micrometers. While the FMM is used to produce blue pixels, the LITI is utilized for the red and green pixels.  In short, the Samsung Galaxy S3 is set to have a gorgeous Super AMOLED screen with true HD resolution that will probably satisfy even the most demanding of screen purists.

The mainstream consumer probably doesn’t want to know the process that takes place behind the making of those fine gadgets that they’re holding in their hands — and that’s fine. But knowing the length that manufacturers went through to create them does make you appreciate technology even more. Now, please hurry up and announce the Samsung Galaxy S3 already!

    The question is Will it finally be as good as the retina display? I own the sg2, the gnex and the iphone and though i prefer the larger screens and appreciate that they are all good displays, the retina display STILL trumps them all so far for sharpness, clarity and color accuracy IMHO.

      Good question. I have a suspicion that a Super Amoled screen that is true 720p resolution without a pentile matrix will. I have the HTC Rezound and its the only phone that has a better display than the iPhone 4/4s. It is an S-LCD that is 1280×720 at 4.3″ and it has a higher pixel density than the Retina Display (342-330). It looks amazing. Text on it is so clear, it looks like printed material.

        The Xperia s has a vastly superior screen than the 4s, no matter if you looked at size, resolution or ppi.

    Weird, I haven’t seen a new “Android tablets will surpass iPad market share” article for several days now!

  • Where do you get 250 PPI for the GS2? IT’s 800×480 pixels at 4.5 inches. That’s only 207 PPI. My T-Mobile Vibrant (aka Galaxy S) is denser: 800×480 at 4 inches, or 233 PPI.

    Interesting that they can’t use LITI with the blue pixels. Must be something with their organic makeup that makes them different from the red and green.

      The 4.5 inch version you’re referring to is either the galaxy s2 skyrocket or epic 4g touch or Tmobile’s variant. The poster is referring to the versions that have not been modified by any U.S. carriers and is 4.3 inches

      • That is also not 250 PPI. 800×480 @ 4.3″ is only 217 PPI. My Galaxy S (Vibrant), the original Galaxy S model, is the same resolution at 4″ with 233 PPI!

    Is that image just a bad fake? Or are there really no “home”/”menu”/”back” buttons on that thing? If the latter is true, the phone is truly useless and the answer presents itself.

      Ice Cream Sandwich ( Android 4.0) utilizes on-screen buttons rather than capacitive or “real” buttons

    • FloatingBrick21

      Just for your information, the iPhone has only ever had one button on the front (home button), and it is the #1 selling phone in the world. Ps: I’m not a fanboy, just stating the facts

    I know that the so-called inferior Pentile screen of the first Galaxy Note looks far superior to anything that was on the market when it came out, including all current IFones, but the Note has been around a long time, now, in market terms.

    Now if they would just get on with bringing the same high-end screen to the Galaxy Note 2, I could stop waiting.

    Apple officially lowered the standards of the Retina Display to 264 ppi with the release of the iPad3. Hell, my old Desire had a ppi of 252, meaning it was only 4.5% lower than a Retina Display. It’s something that I haven’t seen any tech sites discuss much… the lowering of an Apple standard rather than a raising of it.

    I have a friend who works in telecom and he had overheard some talking “above his pay grade” that the carriers will get their official information soon. He quoted “it’s only a matter of weeks now”.
