Samsung Used PenTile AMOLED Display In Galaxy S III Because Of Longer Life

Samsung was able to unveil its flagship smartphone, Galaxy S III, in a lot of style and thunder. The whole tech world was hooked up to the event to see exactly what the company is going to unveil and when S III was finally unveiled, a lot of us were indeed mesmerized. However, there are some things about S III that have failed to impress the tech world.


The most notable of these features is the fact that Samsung has used Pentile AMOLED Display in its new smartphone. A lot of us have been hoping for a higher-resolution, better-pixilated display. The world is fast moving towards higher-resolution devices, as we did see in Apple’s new iPad. But apparently, Samsung still thinks that AMOLED Displays have some life left in them.

AMOLED displays are by no means bad. In fact, they are really good and are able to show displays with very vibrant colors. However, one catch with such displays is that they may turn faulty over time. This, Samsung says, is a result of blue pixels on the AMOLED display.

However, the company that in S III, it used PenTile AMOLED displays which contains more green pixels than red and blue, so that the lifespan of the display has been extended far beyond its earlier lifespan. But, is it really necessary to extend the lifespan of a device that long, given the fact that consumers have a tendency to change their smartphone devices real soon these days.

  1. When the Galaxy S III was announced last week its 4.8-inch display was met with a mixture of ambivalence and incredulity. Ambivalence because 720p resolution is no longer surprising on a smartphone; incredulity because Samsung chose to go with a PenTile matrix for its Super AMOLED screen.

    Long deemed the best mobile displays on the market, Samsung’s Super AMOLED technology provides deeper blacks, richer colours and better viewing angles than the equivalent LCD. When the Galaxy Nexus debuted with a 4.65-inch HD Super AMOLED it was only natural to assume that the company’s next flagship would move on from the red-green-blue-green pixel alignment in favour of a true RGB palette.

    According to representative Philip Berne, Samsung could have used a non-PenTile array, but doing so would have shortened the life of the display. Blue subpixels tend to degrade faster than their green or red equivalents, so having more green subpixels ostensibly extends the life of the screen. Because customers tend to hold onto phones for up to three years, Samsung needs to ensure that the Galaxy S III looks great from year to year.

    PenTile has become controversial because one-third fewer subpixels makes up the total pixel array, leads to a slight blurring of text, and gives an overall fuzziness to shapes. Regular pixels are made up of an RGB-RGB combination, while a PenTile screen uses RG-BG, as the human eye is more sensitive to green. It is less of an issue with higher-resolution screens, and Berne ensures us that the issue is moot on the Galaxy S III due to smaller gaps in the subpixel array itself.

    But the debate will never disappear until PenTile disappears, and that doesn’t seem to be happening anytime soon. While I loved the screen on the Galaxy Nexus, it doesn’t have the same stunning clarity of the Super LCD 2 screen on the HTC One X.

    We’ll reserve our judgements until we get our hands on a review unit, but in the meantime, let us know if PenTile matters to you.
