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

AMOLEDs today

AMOLED displays today are used in many applications - and are most common in smartphones. Samsung for example uses AMOLED displays in most of its high-end phones, including the latest Galaxy S9 and S9 Plus and the Note 9. Apple's new iPhones, SmarthWatches, and the MacBook Pro's Touch Bar are all using AMOLEDs. Other AMOLED devices include smartphones from Huawie, Sony, Xiaomi and others.

AMOLED displays are also used in OLED TVs - which are mostly available from LG. OLED TV screens range from 55" to 77" (88" 8K ones are coming in 2019), and are considered to be the best TV panels ever produced. In 2019 we will have the first rollable OLED TV - LG's 65" Signature OLED R.

AMOLED: Active Matrix OLED

The term AMOLED means Active-Matrix OLED. The 'active-matrix' part refers to the driving electronics, or the TFT layer. When you display an image, you actually display it line by line (sequentially) as you can only change one line at a time. An AMOLED uses a TFT which contains a storage capacitor which maintains the line pixel states, and so enables large size (and large resolution) displays.

AMOLED vs PMOLED

A PMOLED uses a simpler kind of driver electronics - without a storage capacitor. This means that each line is turned off when you move to the next line. So let's say you have 10 rows in your display - each row will only be on 1/10 of the time. The brightness of each row has to be 10 times the brightness you'd get in an AMOLED. So you use more voltage which shortens the lifetime of the OLED materials and also results in a less efficient display. So while PMOLEDs are cheaper to make than AMOLEDs they are limited in size and resolution (the largest PMOLED is only 5", and most of them are around 1" to 3"). Most PMOLEDs are used for character display, and not to show photos or videos.

Flexible, foldable and rollable AMOLEDs

One of the main advantages of AMOLED displays is that they can be made flexible. Flexible AMOLEDs are already popular for many years in smartphones and wearables, and in 2019 we will experience the first foldable devices and rollable screens.

Transparent AMOLEDs

Several companies are developing large transparent AMOLED displays - and in past years we've seen many prototypes - including a large 55" Full-HD transparent TV. But this technology is not commercial yet, mostly it seems because there are no useful applications that will convince the display makers to mass produce such panels.

The latest AMOLED news:

INT Tech developed a 5,000 nits AMOLED microdisplay, is still on track for mass production in Q4 2021

Taiwan-based INT Tech announced that it has produced new AMOLED microdisplay samples at its $143 million fab in Taizhou in Zhejiang province, China, and the company is still on track for mass production in Q4 2021.

The new 0.7-inch INT Tech uNEEDXR display is a direct-emission display that features a brightness of over 5,000 nits, 3147 PPI and a low power consumption (less than 500mW@5000nits).

DSCC: over 600 million smartphone OLED displays will ship in 2021, over 750 million in 2022

DSCC says that OLED shipments in the second quarter of 2021 rose 36% over last year (but decreased 10% compared to Q1 2021). New smartphone launches by Samsung, Apple and Google will drive the growth at the second half of 2021.

Samsung Display is still the leading smartphone OLED producer, with a market share of 73.5% in Q2 2021. BOE was at second place with a 6.7% share.

TCL to start supplying smartphone OLED displays to Samsung Electronics

According to reports from China, TCL will start supplying smartphone AMOLED panels to Samsung Electronics. TCL is already supplying LCDs to Samsung (for both phones and TVs), but this is the first time it will supply OLEDs as well.

Samsung is looking to lower its smartphones production costs, and so it widens its OLED supply chain. Up until now, the company relied 100% on AMOLEDs produced by Samsung Display, but earlier this year it started to buy OLED panels from BOE.

DSCC: the AMOLED material market to grow to $1.4 billion in 2021, $2.18 billion in 2025

DSCC updated its AMOLED material market forecast, saying that the market will reach $1.4 billion in 2021 (up 32% from 2020), and grow at a 16% CAGR from 2019 ($927 million) to 2025, to reach $2.18 billion by 2025.

AMOLED material revenues  forecast (2019-2025, DSCC)

DSCC takes a look into the material cost for LG Display's WOLED TV panels. LGD will likely manage to implement incremental improvements in material utilization and price, which will enable the company to almost halve the material cost of its TV panels- from $88.14 per sqm in 2019 to $47.19 per sqm by 2025.

Samsung to launch a new OLED device stack, to be first adopted by the Vivo IQOO 8 Pro smartphone

According to reports, Vivo will soon release its latest IQOO smartphone (IQOO 8 Pro). The phone will use an AMOLED display produced by Samsung Display. This panel, in fact, will be the first one to adopt Samsung's latest E5 OLED stack.

We do not have any information on this new stack, but OLED companies keep improving the material stack to enable higher efficiency - and sometimes to increase the color gamut, reduce costs or improve other performance points. Hopefully Samsung will announce the E5 stack officially soon.

OLED-Info overhauls its Automotive OLED Market Report

In early July, we published our quarterly update for our Automotive OLED Market Report. The update this time was comprehensive, as we overhauled the complete report.

The OLED Automotive market is heating up. AMOLED displays (mostly flexible ones) are finally being adopted by commercial cars, while OLED lighting panels continue to be designed into high-end automotive taillights as the ultimate lighting solution.

DSCC increases its OLED market forecasts as it sees increased adoption in phones, tablets, monitors and laptops

DSCC has published its latest OLED market forecast. The company raised its 2021 revenue expectations by 9% (to $42.5 billion) as it sees increased smartphone display shipments and higher OLED laptop shipments.

AMOLED revenue forecast (2021-2025, DSCC)

DSCC also increased its long term OLED revenue forecast by 11% to $60.6 billion by 2025. This is driven, again, by higher smartphone AMOLED shipments and increased adoption in IT markets (tablets, laptops and monitors).

Samsung Display to convert an LCD fab to a 6-Gen flexible OLED production line in a $2.7 billion investment

According to reports from Korea, Samsung Display plans to build a new 6-Gen flexible OLED line. The new line will replace a current LCD line that is used to produce TVs at SDC's Asan plant (the LCD 7-2).

The new fab, which will cost around 3 trillion Won ($2.7 billion USD) will have a monthly capacity of 30,000 monthly substrates. This will increase SDC's AMOLED production capacity to 195,000 monthly substrates, not counting its upcoming QD-OLED production line.

Tianma shows a microLens AMOLED panel with improved power consumption

Tianma demonstrated a new AMOLED display panel at SID Displayweek, that sports a micro-lens array that helps to decrease power consumption by 10-15%.

Tianma 6.2'' microLens (MLP) AMOLED (SID Displayweek 2021)

The so-called MLP panel is 6.2" in size with a 876x2142 resolution (373 PPI) and a brightness of 420 nits. The pixel configuration is, interestingly, YYG - yellow and green sub-pixels, which means that this display uses color filters.
