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).
Super AMOLED vs Dynamic AMOLED
In 2019 Samsung introduced its next-generation mobile display technology, which it calls Dynamic AMOLED. Basically a Dynamic AMOLED is similar to a Super-AMOLED display, but it adds HDR support. It seems as if Samsung is no longer using the Dynamic AMOLED brand for its latest displays.
The latest Super AMOLED news:
Samsung announced several new OLED devices yesterday. We'll start with the new Galaxy Note 20 which sports a 6.7-inch 1080x2400 HDR10+ Super AMOLED Plus display (which could mean this is an RGB display, not a Pentile one). The Galaxy Note 20 Ultra has a larger 6.9-inch 1440x3088 Dynamic AMOLED. The display supports a refresh rate of 120Hz at Full-HD resolution and 60Hz at QHD. According to the Elec in Korea, the Note 20 Ultra display has an LTPO backplane (which Samsung calls HOP).
Next up is the company's 2nd generation Galaxy Z Fold 2 that is an update to the original fold with a larger internal foldable display at 7.6" 1768x2208 HDR10+ 120Hz Dynamic AMOLED and also a larger 6.23" 816x2260 Super AMOLED cover display. The Fold 2 also improves the hinge design and sports an ultra-thin-glass cover (like the Galaxy Z Flip).
OnePlus now officially announced that its next phone (the OnePlus 8) will feature a high-end AMOLED, developed in collaboration with Samsung, that will feature a refresh rate of 120Hz, a peak brightness of 1,000 nits, 10-bit color support and a 2K+ resolution. OnePlus again brands its Super AMOLED displays as Fluid Display. The touch sample rate will be 240Hz and the phone will include a hardware MEMC smooth-video accelerator.
OnePlus launched it latest flagship smartphones, both of whom utilize high-end AMOLED displays. We'll start with the OnePlus 7 Pro - a flagship smartphone that features a large 6.67" 90Hz 1440x3120 Fluid AMOLED - which apparently is a 90Hz Super AMOLED. This is a full-screen display that has an under-the-display fingerprint sensor.
The OnePlus 7 has a smaller notch-type 6.41" 1080x2340 Optic AMOLED - which is again OnePlus' own display marketing term for an SDC's Super AMOLED. It seems as if OnePlus brands its regular 60Hz AMOLED displays as Optic Displays - and its higher-end 90Hz ones as Fluid AMOLEDs.
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.
Samsung's Tab S5e offers mid-range performance with a snapdragon 670 octa-core chipset, 4/6 GB of RA and 64/128 GB of storage (with a microSD slot). The 7,040 mAh battery provides up to 14.5 hours. The Galaxy Tab S5e is now shipping starting at $399.
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.
Update: the video has been removed, but the Galaxy Fold device has been announced.
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: Samsung yet again improved its AMOLED displays, the Note 9 has the best mobile display ever
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.
