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.

Looking to buy an AMOLED display?

Are you looking to adopt an AMOLED display for your device? Several producers are already making panels - including Samsung Display, LG Display, EverDisplay, Truly, Visionox and more. AMOLEDs on the market range from small 1-inch ones for smartwatches through large OLEDs used in tablets and laptops - to large TV panels.

IHS details the production costs of smartphone OLED displays, say rigid OLEDs carry a 20% premium over LCDs

IHS released its LCD and OLED smartphone display cost model for Q3 2018. According to IHS, a 5.7" 2560x1440 rigid OLED costs $18.62 to produce, a full-display flexible curved 5.8" 2880x1440 OLED costs $22.61 and a Notch-type 5.9" 2438x1125 OLED costs $28.18 to produce.



It is not clear how IHS estimates yields - from our information SDC's production yields are much higher compared to the new makers such as BOE and LG Display - which means that yielded costs are much lower at SDC's mature OLED fabs.

New 960fps videos show the fast refresh cycle of high-end AMOLED displays

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.

Dell announces new OLED laptops and a 55" gaming OLED monitor

Dell announced that its premium 15" laptops will all get an optional OLED display in 2019. The Dell XPS 15, Dell G7 15 and the Alienware m15 will all offer a 15" OLED display that features HDR, a 100% DCI-P3 color gamut and 100,000:1 Contrast Ratio.

The new 15" Dell OLED laptops will start shipping in March 2019. That's great news from Dell, and it's a great start for 2019 as it seems to be poised for an OLED laptop comeback.

Razer unveils a concept 15" 4K OLED laptop

Razer unveiled two new laptop concepts at CES, based on the company's 15" Razer Blade laptop. One of the concepts spots a 4K touch OLED display (the second used a 240Hz FHD LCD).

Razer says that the OLED display delivers "amazing color, deep blacks, and efficient performance". The company did not disclose if and when it aims to release this as an actual product.

Sony announces its 2019 OLED TV range, with two TVs, the A9G and A8G

Sony announced its 2019 TV range, with two new OLED TVs. First up is the Master-Series A9G, that offers "consumer reference-quality image" and features Sony's X1 Ultimate Picture Processor, Pixel Contrast Booster and an automated calibration mode (including a dedicated mode for Netflix).

The A9G will be available in 55", 65" and 77". The Android TV features Sony's Acoustic Surface Audio - which means that the TV stand doubles as a high end speaker.

LG launches its first rollable TV, the 65" OLED TV R

As was reported last month, LG Electronics announced its first rollable TV (and the world's first rollable OLED devices), the 65" Signature OLED TV R. LG's new TV can roll up into its base, and has three viewing options - full view, line view and zero view. In Line View, there are six different modes, in which the TV can show the weather, the time, a home dashboard and more.

LG's OLED TV R, like the rest of LG's 2019 OLED range, is based on the company's 2nd-gen Alpha 9 intelligent processor the enables LG's ThinQ AI to offer new display algorithms and Amazon's Alexa and Google's Assistant. The TV also features HDMI 2.1, high frame rate (HFR) support, enhanced audio return channel (eARC), variable refresh rate (VRR) and automatic low latency mode (ALLM). LG's flagship OLED also feature Dolby Atmos for immersive entertainment.

LG Display to unveil new transparent, automotive, 8k and CSO OLEDs at CES 2019

LG Display announced the OLED displays it will demonstrate at CES 2019, starting on Tuesday January 8th. We already know that LG Electronics will launch a 88" 8K OLED TV (the OLED Z9) but now LGD says it will demonstrate a 88" Crystal Sound OLED (CSO) panel - which has a sound system built into the panel (which acts as the membrane).

According to our information, LG Electronics will also demonstrate its rollable TV at CES (and maybe launch it as a product too) and may also bring its first foldable smartphone to the show as well.

Business Korea: LGD delays the construction of its P10 fab

Towards the end of 2015 LG Display announced that it plans to build a new OLED fab (P10) in Paju in a $8.7 billion investment. The P10 was supposed to produce both LCD and OLED displays (mostly OLED TV panels, but also mid-sized flexible OLEDs), and production was planned to begin towards the end of 2018.

In 2017, we heard reports that LGD decided to cancel the LCD production at the P10 fab and focus exclusively on OLED displays. A new report from Business Korea confirms this report - and says that LG also decided to postpone the production at the P10 as the shift to OLED technologies is challenging - especially as LGD intends to produce OLEDs on 10.5-Gen substrates for the first time at the P10 fab.

BOE announces plans for its fourth flexible OLED line, in Fuzhou, Fujian

Earlier this month we reported that BOE started to construct its 3rd 6-Gen flexible AMOLED production line in Chongqing's Liangjiang district (the B12 line). The Chongqing line will join BOE's first flexible 6-Gen OLED fab in Chengdu (the B7) and its second line in Mianyang.


BOE now announced plans for another large investment in a new flexible OLED fab, this one in Fuzhou, Fujian. This fab will be similar to BOE's other fabs - a 6-Gen (1500×1850 mm) line with a capacity of 48,000 substrates. The investment will total 46.5 billion Yuan (about $6.75 billion USD). This fourth line will bring BOE's total flexible OLED capacity to 192,000 monthly substrates.
