OLED displays use organic materials that emit light when electricity is applied. OLEDs enable emissive, bright, thin, flexible and efficient displays. OLEDs are set to replace LCDs in all display applications - from small displays to large TV sets.

Samsung's Super AMOLED Plus displays were an 2011-2012 upgrade to the company's Super AMOLED displays. Super AMOLED Plus display used a regular (RGB strip) sub pixel scheme as opposed to the Pentile Matrix used in 'regular' Super AMOLED displays. Only a handful of devices, shipped in 2011 and 2012 by Samsung and other companies did use Super AMOLED Plus displays. Samsung seems to have stopped using this brand and are now focused on Pentile scheme for all of its AMOLED panels.

Super AMOLED Plus devices

Super AMOLED Plus was announced in CES 2011, together with the first phone to sport these displays - the Infuse 4G. The display was a 4.5" one. Samsung's Galaxy S2 also had a Super AMOLED plus display (4.3" WVGA)

Samsung also adopted a Super AMOLED Plus display in their first OLED Tablet, the Galaxy Tab 7.7 (7.7" 1280x800 display).



Is Super AMOLED Plus dead?

The last device to actually sport a Super AMOLED Plus display was BLU's Vivo 4.3, a Dual-SIM smartphone introduced in 2012. Since then Samsung did not release any new device with a Super AMOLED Plus display - all of Samsung's newest phones and tablets use a 'regular' Super AMOLED display (with a Pentile Matrix).

The Galaxy Note 2 uses a non-pentile OLED display at 267 PPI

Sep 05, 2012

When Samsung announced the Galaxy Note 2, with its 5.5" 1280x720 HD Super AMOLED display, I assumed it was a Pentile display. But it seems that the Note 2 actually uses an RGB matrix in a unique arrangement (see the photo below). Samsung calls this new matrix S-Stripe. This is rather confusing on several accounts - mostly because up till now Samsung used the brand Super AMOLED Plus for non-pentile OLEDs.

Samsung S-Stripe Matrix

Just a few weeks ago we explained that Pentile OLED displays enable higher lifetime, and we were told that for an RGB OLED with over 230 PPI, lifetime becomes too low for Samsung and they choose Pentile in those displays. But the Note II has a PPI of 267 - the highest PPI non-Pentile OLED. This means it has a lower lifetime compared to a Pentile display (but the advantage is that there's no visible Pentile pattern of course).

Nouvoyance explains why PenTile OLEDs last longer

Aug 05, 2012

A few months ago Samsung said that the new Galaxy S3 has a Pentile display (a 4.8" 1280x720 HD Super AMOLED one to be exact) because PenTile increased the lifetime of OLED panels. I have discussed this with Joel Pollack, an Executive VP at Nouvoyance (Samsung's company that developed the PenTile matrix scheme), and he explains this claim further.

An OLED display is made from colored (RGB) sub pixels. A blue OLED has the lowest luminous efficiency (lower then red and green) and so needs to be driven at higher current - which means a lower lifetime.

DisplayMate presents a Galaxy S range shootout - sees rapid performance improvements

Jul 12, 2012

Raymond Soneira, our friend and display guru from DisplayMate have posted a very interesting and detailed comparison of the OLED displays in the Galaxy S, SII and SIII phones. He says that while all three OLED panels performed very well, there has been a rapid and significant improvement in OLED performance (especially power efficiency) in just 2 years.

Raymond says that high-end LCDs are brighter and more power efficient than OLEDs for text and web applications. OLEDs are better for photos and videos. He also says that while the performance is excellent, it's been compromised by Samsung's implementation choices - especially the low brightness due to power constraints (although low reflectence on those devices mean that high brightness is not critical in most situations).

Engadget reviews the S3: the display is great, better than older AMOLEDs

May 27, 2012

Engadget posted a review of the Galaxy S3, and while they think the phone is excellent, they're not sure if the S3 is the best Android phone on the market, with the main competitor being the HTC One X. They love the 1280x720 4.8" Super AMOLED HD display, and say that there are real visual improvements over the Galaxy Nexus. The colors aren't over-saturated and there's no unnatural blue-ish tint.

Samsung Galaxy S3

Regarding the controversial PenTile technology, Engadget says that it isn't so visible because the screen is large and you tend to hold it from a little bit further than in smaller phones. But it still makes text a bit fuzzy, and so if you like reading on your book, maybe it's better to choose a non-Pentile phone (I personally think it's better to use a dedicated e-paper e-reader if you actually want to read).

Samsung producing sample Super AMOLED Plus HD displays, used in Tizen developer phone?

May 12, 2012

Just a few minutes ago we posted about Samsung's claim that they used Pentile in the Galaxy S3 because it lasts longer. There are some reports however that Samsung already managed to produce Super AMOLED HD Plus 4.8" display. In fact it is said that they are using this display in a Tizen (open source OS) development model that they handed out to some developers.

It may be that Samsung cannot yet mass produce such displays, and so they couldn't use it in the S3. Anyway we'll probably know more soon...

Samsung - we keep using PenTile AMOLED displays because they last longer

May 12, 2012

Update: We discussed this with Nuovoyance's VP, he explains better why PenTile displyas lasts longer...

Some people really dislike Pentile displays, but Samsung keep producing AMOLED with PenTile - even in their flagship devices such as the new Galaxy S3 (which sports a 4.8" 1280x720 HD Super AMOLED). Today we hear that Samsung says that one of the major advantages of PenTile AMOLED displays is increased lifetime.

In PenTile displays, there are twice as many green subpixels as there are blue suxpixels. Blue OLEDs feature the lowest lifetime, and so Pentile displays "tend" to last longer, according to Samsung. In any case, as the resolution gets higher, it's getting harder to actually notice the "fuzziness" caused by the Pentile Matrix...

Verizon to launch the Galaxy Tab 7.7 next week

Feb 28, 2012

Verizon announced that it's going to launch the Galaxy Tab 7.7 LTE on March 1st - for $499.99 with a contract. Amazon.com offers the tablet unlocked for $650, but without LTE (only 3G/Wi-Fi). The Galaxy Tab 7.7" got some great reviews - Engadget says it's the best 7" tablet and praises the "stunning and breathtaking" Super AMOLED Plus display.

The Galaxy Tab 7.7 is the world's first tablet with an OLED display, a 7.7" Super AMOLED Plus panel, offering 1280x800 resolution. Other specs include Android v3.2, Dual-core 1.4 Ghz processor, HSPA+ radio (LTE in some models), 16GB to 64GB internal storage and a microSD slot, Wi-Fi, GPS and two cameras (3MP and 2MP).
