What is an OLED display?

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.

TCL shows a smartphone concept that includes a rollable and foldable OLED display

Chinese smartphone producer TCL unveiled an interesting new smartphone prototype (concept?) called the Fold ‘n’ Roll.

As you can see in the video, the device has a 6.87-inch OLED display when fully folded. It can open up (out-folding) into a 8.85-inch display, and then it can open even further to a 10-inch tablet-like device using a rolling mechanism. The display itself is produced by TCL's CSoT subsidiary.

Android Authority are really impressed with the foldable Huawie Mate X2

Last month Huawei started shipping its second-generation foldable smartphone, the Mate X2, and the first review, from Android Authority is in. And the reviewer really likes the device - saying it may even be better than Samsung's own foldable smartphones.

The inner-folding 8-inch 90Hz 2480 x 2200 AMOLED is said to be beautiful, and it is completely flat when open - with a really minimal bezel that can barely be seen. According to the reviewer, that's a huge improvement over all other foldables they used. The phones feels very solid, in fact, and the hinge seems much more durable than before.

Ming Chi Kuo: Apple to adopt OLED displays in the 2022 iPad Air

In late 2020 several reports from Korea suggested that Apple is looking to adopt OLEDs in future iPad devices, as early as in 2022.

According to Ming-Chi Kuo, a usually reliable Apple analyst, Apple is looking to adopt an OLED display in the 2022 iPad Air (while the MacBook Air will start using miniLED LCDs). MiniLEDs are actually more expensive than OLEDs today (these iPad OLEDs will be the cheaper rigid variant) and so cheaper iPads or laptops will use OLEDs from 2022 and onwards, while more expensive models will opt for miniLEDs which do not suffer from burn-in.

EDO progresses towards its IPO, will use the funds to construct a new 6-Gen AMOLED fab

Earlier this month we reported that China-based AMOLED producer EverDisplay (EDO) has become a public company. We have been a bit early, but the company is progressing on its IPO registration and has released some more information regarding is business.

The company is raising 10 billion Yuan ($1.5 billion USD) and most of these funds will be used to construct the company's new 6-Gen AMOLED line. As you can see in the image above, almost all the company's OLED panels are used in smartphones and wearables. But in 2020 the company also started to produce laptop and tablet displays - EDO recently started to make 11", 12.8" and 15.6" rigid and foldable AMOLED displays for laptop devices. We list many EDO OLED displays in the OLED Marketplace.

DSCC posts its latest outlook for the OLED materials market

DSCC posted an interesting post with its latest views and forecasts on the OLED material market. The company expects AMOLED stack material sales to grow at a 18% CAGR in the next five years, from $294 million in 2019 to $2.46 billion in 2024. Compared to its previous estimate, DSCC sees higher sales as demand for OLED TVs and OLEDs in the IT market (tablets and notebooks) is increasing.

DSCC also posted an analysis of LGD's new evo OLED material stack. Compared to LGD's "standard" WOLED stack, the evo adds an emitting green layer to improve the brightness by 20%. This of course adds an extra material cost to the panel price.

Samsung Display to introduce more than 10 new AMOLED displays for laptops in 2021

Samsung Display started producing 15.6" 4K AMOLED displays in 2019 for the laptop market, which kickstarted the OLED laptop market as several leading makers (including HP, Lenovo and Dell) started to offer high-end OLED laptops. Since then SDC added more OLED laptop displays to its lineup, and other OLED producers (such as EDO and BOE) started to offer laptop panels as well.

ETNEws: Apple aims to start using OLED displays in iPad devices in 2022

Last month we posted that the Korean Elec publication claims that Apple is aiming to adopt OLEDs in its next iPad Pro devices - and as Apple wants extended lifetime from these panels, the Korean panel makers are developing tandem OLED devices (easier for LG as it is already producing such panels for automotive applications).

Today another Korean publication, ETNews, has posted that Apple is aiming to start using OLEDs in its iPads in 2022. According to ETNews, Apple indeed reached out to both LG Display and Samsung Display for these OLEDs.

Apple aims to adopt tandem OLEDs in its next iPad Pro tablets

In a very interesting post, The Elec states that Apple has reached out to both Samsung Display and LG Display, requesting that the display suppliers develop a longer-lifetime OLED display for Apple's next iPad Pro devices.

The lifetime of the current crop of mobile OLED devices is not enough for Apple's iPad - which is designed to be used for a longer period of time compared to a smartphone. An increased lifetime will also result in lower burn-in problems which seem to trouble Apple.

Samsung launches several new AMOLED devices, including the Note 20 and the Galaxy Z Fold 2

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).
