OLED is short for Organic Light Emitting Diode, a device composed of thin carbon-based films placed between two electrodes that creates light with the application of electricity. Unlike other screen technologies, (like LCDs), which require backlighting, OLED displays are emissive devices - they emit light rather than manipulate transmitted external light.
OLEDs provide brighter, crisper colors and contrast on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today. This revolutionary technology is fit for various types of screens, like computer screens, mobile phones, tablets, TVs and more. OLED screens are light, thin, high-resolution and contain individually-lit pixels that make for true blacks and superior color contrast.
The current OLED tablet market
OLED displays are already very common on mobile phones (in fact about a quarter of all mobile phones now ship with an OLED - and that percentage is climbing as Apple, Samsung, LG, Huawei and others adopt OLED displays in their best smartphones).
OLEDs are just now starting to make inroads into the tablet market, though - as these larger displays carry a high premium over competing LCDs. The leading company that produces and adopts OLEDs is Samsung, and indeed the company's latest high-end tablets all use OLED displays.
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).
These new 11", 12.8" and 15.6" AMOLEDs are now available in the OLED Marketplace. This is great news from EDO, as up until now Samsung Display was the exclusive supplier of AMOLEDs for tablets and laptops.

Following three months of re-design, Samsung now announced that it fixed all the issues in its foldable smartphone and is ready to start shipping in September 2019. Here are the list of changes that Samsung announced, including both design and construction improvements:
According to a report from Korea, when Apple secured its flexible AMOLED supply from Samsung for the iPhone X (and later XS and XS Plus) it committed to a minimum order quantity. As sales of the iPhones were slower than expected, the company did not reach its MOQ, and is now facing penalties of hundreds of millions of dollars.
It seems as if Apple is reluctant to pay the penalty (which isn't a big surprise) and is offering some alternative routes for Samsung - including the option of ordering OLED displays for future iPads or laptops (this coincides with a report from Korea last month).
Korea-site The Elec says that according to its sources, Apple is "considering adoption" of OLED displays in its Pro laptop and tablets lines. The iPad Pro will adopt an 11" OLED while the MacBook Pro will adopt a 15.6" one.
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.
DSCC says that OLED market revenues will grow from $26.5 billion in 2018 to $28.7 billion in 2019 and over $52 billion by 2023. The largest application will remain smartphone displays, but several other applications will generate over $1 billion in 2023 - TVs, tablets, notebooks and monitors. By area of production, TV displays will surpass smartphone displays in 2021.
Samsung is still (and will remain so) the dominant AMOLED display producer, even though its market share will drop from 97% in Q1 2018 to 81% in Q4 2019. In Q1 2019 Visionox surpassed LGD to become the 2nd largest AMOLED producer (but most of Visionox's panels are low-end 5.5-inch panels). DSCC expects LGD to regain its number 2 position in the second half of 2019. BOE is the third player and will remain so following its supply agreement with Huawei.
Huawei launched its first foldable smartphone, the Mate X with a glorious 8" 2200x2480 foldable AMOLED display that folds outwards. When closed, the phone operates as it has two displays - a 6.6" 1148x2480 on the front and a smaller 6.38" 2480x892 display on the back (which makes room for the cameras).
The Mate X specifications include 5G connectivity, a Kirin 980 octa-core chipset, 8 GB of RAM, 512 GB of storage, a NM memory slot and a quad camera setup with Leica optics.
Samsung finally officially launched its Galaxy Fold foldable smartphone device. The Galaxy Fold features a 7.3" 1536 x 2152 foldable Infinity Flex AMOLED display that folds inside, in addition to a secondary cover display - a 4.6" 840×1960 Super AMOLED.
Besides the exciting foldable display, the phone/tablet device features an octa-core chipset, 12 GB of RAM, 512 GB of storage, a large battery, triple camera setup on the back and dual front cameras.
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.
