display matrix, not the

. A PenTile display uses a different subpixel layout (one red and one blue subpixel for every two green ones). In other words, it’s not quite as sharp and could show color fringing along the edges of images, especially when compared to Samsung’s much revered Super AMOLED Plus displays.
So why did Samsung go PenTile for the S III? According to
MobileBurn, it’s apparently all about screen longevity. Samsung states that Super AMOLED Plus displays have a tendency to deteriorate over time, especially the blue subpixels, which actually degrade the fastest. Since PenTile displays feature fewer blue subpixels, they will last longer, says Samsung. Also, since the pixel density of the S III’s screen is much higher due to its high resolution, the PenTile issues are minimized and most people cannot see the difference in quality.
Samsung will undoubtedly keep working on the Super AMOLED Plus technology and make it last longer without resorting to a PenTile matrix. Until then, my advice is to judge for yourself by actually using an S III to see if it looks acceptable to you… which in most cases it probably will unless you’re looking at the screen under a microscope.
Nice processor, shame about the Pentile. It's something that several people have been saying about Samsung's new chest-beating

? According to Samsung's spokesperson, it's because those blue sub-pixels that are absent on Super AMOLED displays degrade faster than their red and green allies. With the aim of keeping its phones healthily glowing for at least 18 months, it made the decision to go with the Pentile formation. Compared to the Galaxy Nexus, which matches the resolution of the Galaxy S III, Samsung has also shrunk the gaps between pixels on its newest phone in an effort to reduce complaints leveled at its Super AMOLED technology -- although we didn't notice it all that much

Samsung says PenTile AMOLED displays offer long-life
The launch of Samsung’s

was met with a muted reception from some sections of the tech community. While its quad-core Exynos processor has been
[ برای مشاهده لینک ، با نام کاربری خود وارد شوید یا ثبت نام کنید ]
, some have criticized its extensive use of plastic materials and some its size. However, one detail in its specifications that probably caused the most consternation is its use of a Super AMOLED PenTile pixel array instead of the Super AMOLED Plus technology found on its predecessor, the

which includes a true RGB array without sharing subpixels.As
Mobile Burn

, a Super AMOLED PenTile display uses an RGBG (red,green,red,green) layout resulting in more green pixels and fewer red or blue pixels. This also results in a lower actual pixel density than displays advertised resolution may suggest – ‘Plus’ (RGB) variants also have 50 percent more subpixels. According to
[ برای مشاهده لینک ، با نام کاربری خود وارد شوید یا ثبت نام کنید ]
, it opted for the PenTile pixel arrangement on this occasion because it has found that PenTile AMOLED displays have a longer lifespan than its Plus variants, although those are generally the preferred choice for display aficionados.
Samsung’s Philip Berne told
Mobile Burn that blue pixels degrade faster than the red or green subpixels, though admitted that the use of a PenTile array can make the edges of images, such as app icons, look ‘fuzzy.’ However, Berne was of the view that the 720p (1280x720) display used on the Galaxy S III has a resolution much higher than the 800x480 WVGA display used the

, significantly reducing any unwanted side-effects of using a PenTile arrangement.
Where that leaves Galaxy S II owners who thought that they had a better quality display is an unknown. The comments by Berne seem

that Samsung executives made when the original 7-inch Galaxy Tab debuted, not with and AMOLED display, but a Super-LCD display. Although Samsung had previously sounded the praises of AMOLED technology as being up to 30 percent more power efficient than LCD displays, Samsung defended its choice at the time saying it used an LCD in the Galaxy Tab because it used less power than the AMOLED equivalent. Not mentioned at the time were possible cost considerations.
A further irony is that the first AMOLED tablet on the market, the

uses a ‘Plus’ variety display using the standard RGB pixel layout. While it is true that the use of different display technologies will have trade-offs, Samsung’s use of the both PenTile and Plus displays, and the purported reasons for doing so seem to be in conflict. The reality is that for most users, however, the ‘PenTile versus Plus’ debate is probably meaningless and will not come into the equation when considering their purchase. What will likely matter more is whether they think the device looks cool or not – which is another debate in itself.

It was generally thought that the Galaxy S III will come with a Super AMOLED HD Plus display, instead of the Super AMOLED HD display found on the Galaxy Nexus.
The Super AMOLED HD Plus display was already being used by Samsung on the Galaxy Tab 7.7 so there was no issue of the technology not being ready in time. However, many people were disappointed to see that the Galaxy S III used the same Super AMOLED HD display with PenTile matrix as the one on the Galaxy Nexus.
A lot of questions were raised as to why Samsung did not use a Super AMOLED HD Plus display on the Galaxy S III. The Korean company finally answered this question at the on-going CTIA to a reporter of
[ برای مشاهده لینک ، با نام کاربری خود وارد شوید یا ثبت نام کنید ]
that Super AMOLED HD Plus displays don’t last as long as the Super AMOLED HD, and so the company went with the Super AMOLED HD display on the S3.
Super AMOLED HD displays have a PenTile (RGBG, 2 green pixels for every blue pixel) sub-pixel arrangement, while Super AMOLED HD Plus has a RGB sub-pixel arrangement. The blue sub-pixels on the Super AMOLED screen degrade the fastest, so since the HD Plus has more blue sub-pixels, the display will not last as long as the former.

After the Galaxy S III announcement many people, including us, were wondering why Samsung decided to use a PenTile Super AMOLED screen instead of an Super AMOLED Plus unit.
Well, a Samsung spokesman has explained why. The reason turned out to be plain simple – it’s not because Samsung can’t satisfy the demand – it’s just that the PenTile will last longer.
As it turns out, the RGB AMOLEDs degrade much faster than the PenTile AMOLEDs so the picture quality becomes worse faster. The blue pixels are the ones to blame – they degrade faster than the red and green pixels. The PenTile displays have less blue pixels because of the RGBG subpixel layout and that’s why they have longer life span.
Samsung wants to ensure top-notch display quality even two or three years after the users get their Galaxy S III and it seems the only way is to use PenTile displays.
Does that mean that the Galaxy S II users have only two years of proper
