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 displays, announced in January 2010, are AMOLED displays for mobile devices (such as smartphones, wearables and tablets) with an integrated touch function. The thickness of the touch sensor is just 0.001 mm and this allows the screen to provide better images and to have great visibility even in direct sunlight compared with regular AMOLED displays with an external touch layer.
Super AMOLED and the PenTile matrix
Samsung's Super-AMOLED displays use a Pentile matrix sub-pixel design. That means that the green sub-pixel is shared by two pixels and the display has only 2 sub-pixels per real 'pixel' compared to the classic RGB matrix design (or Real-Stripe). You can see a PenTile matrix vs a Real-Stripe one on the images below (the PenTile is on the right). Newer Super AMOLED displays use a different PenTile matrix (Diamond Pixel pattern).
Samsung started shipping its flagship tablet the device, the Galaxy Tab S5e - Samsung's thinnest tablet yet at 5.5 mm. The S5e features a 10.5" WQXGA (2560x1600) Super AMOLED display with a 81.8% screen-to-body ratio.
A report from China suggests that Samsung sold over 500,000 units of its new flagship Galaxy S10 smartphones in China in only 7 days. it tok 30 days to achieve the same number of sales for Samsung's GS9 smartphone in 2018. Within two weeks of its launch, the GS10 is sold out in Hong Kong.
Reviews on Samsung's GS10 has been very positive, and Samsung expects to sell 40-45 million units in 2019.
Samsung announced a handful of new devices, all with OLED displays. We'll start with the company's 2019 flagship smartphone, the Galaxy S10. It includes four different variants -
Galaxy S10 5G: 6.7" 3040x1440 flexible AMOLED
Galaxy S10+: 6.4" 3040x1440 flexible AMOLED
Galaxy S10: 6.1" 3040x1440 flexible AMOLED
Galaxy S10e: 5.8" 2280x1080 AMOLED (rigid?)
The S10 phones use Samsung's latest AMOLEDs, that are now HDR10+ certified, include an under-the-OLED fingerprint sensor (Qualcomm ultra-sonic) and cut-outs for the selfie cameras. Samsung calls these displays "Dynamic AMOLED" (due to the HDR support, probably) and "Infinity-O Display" due to the camera cut-outs.
In November 2018 Samsung unveiled its upcoming foldable smartphone, and according to reports it may officially launch this new product on February 20th (at the Samsung Galaxy S10 unveiling event). Samsung Vietnam accidentally published an ad showing several new technologies, including a foldable smartphone:
Samsung first foldable smartphone/tablet device will use two OLED displays - a large 7.3" 1532x2152 foldable AMOLED that folds inside, and a smaller secondary OLED (4.5" 840x1960). Samsung brands the foldalbe display as the Samsung Infinity Flex Display.
BlurBusters posted an interesting article that uses high-speed video (960fps) capture to show the advantages of OLED displays over LCDs in terms of response time.
In the video above, you can see the almost instantaneous response times of the 10.5" 2560x1600 Super AMOLED display of Samsung's Galaxy Tab S4. In the video below, you can see the response time at 960fps of Apple's MacBook Pro 2015 (IPS LCD). Blurbusters explains that the Gray-to-Gray (GtG) response time of the OLED is around 0.1 ms - far better than the 5 ms one of the LCD.
DisplayMate posted a review of Samsung's latest OLED display - the 6.4" 1440x2960 (516 PPI) flexible Super AMOLED used in the Galaxy Note 9. As we've seen many times before, Samsung managed to significantly improve its OLED quality - and DisplayMate says that this is the best mobile display ever tested.
In the Galaxy Note 9, Samsung concentrated on significantly raising the on-screen absolute picture quality and absolute color accuracy by implementing precision factory display calibration. This could have been a response to the excellent calibration done by Apple in the iPhone X.
The Korea Herald says that Samsung told its suppliers that its target is to sell 43 million GS9 (and GS9 plus) phones in 2018. In 2017, Samsung shipped 41 million GS8 and GS8 plus phones. In 2016, Samsung shipped 48 million GS7 phones, so even if it reaches its target of 43 million GS9 phones, it will still lag behind The GS7.
According to reports from Korea, pre-orders for the Galaxy S9 in Korea are 30% lower compared to the pre-orders of Samsung's Galaxy S8 in 2017. Yonhap news says that Korea's three largest carriers distributed only 180,000 GS9 phones, while at the same time last year these three companies distributed 260,00 GS8 phones.
Samsung introduced its Galaxy S9 flagship phone a couple of days ago, with its flexible 5.8" 1440x2960 (570 PPI) Super AMOLED display (6.2", 529 PPI, on the S9 Plus).
Display measurement experts from DisplayMate already tested the new display (with a pre-production GS9), and published a comprehensive report. As expected, Samsung continues to improve its OLED displays, and the GS9 again is announced by DisplayMate to be the world's best ever mobile display, better than the iPhone X OLED.
