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.
An AMOLED display is an OLED display that is driven by an active matrix backplane, it is a type of OLED display that can achieve high performance. Most OLED displays such as the ones used in TVs and smartphones are actually AMOLED displays.

What does AMOLED mean?
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.
AMOLEDs today
AMOLED displays today are used in many applications - and are most common in smartphones. Most smartphones today use AMOLED displays - including the latest Samsung phones, all of Apple's iPhones models and more.
AMOLED displays are also used in OLED TVs, many wearables (such as the Apple Watch), tablets, laptops, VR headsets, monitors, and more.
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.

The latest AMOLED news:
AUO may close down its AFPD OLED fab in Singapore as it focuses on microLED for next-gen wearable and automotive displays
AU Optronics has a 4.5-Gen AMOLED production line in Singapore, active since around 2013. The AFPD line is a small-scale operation, and AUO never managed to expand its capacity and compete with large AMOLED producers.
According to a report from Japan, AUO is now considering closing down the AFPD line, and converting it to microLED R&D production line. It could move it back to Taiwan, or retain Singapore as a hub for AUO in Southeast Asia. The company will make a final decision, it seems, in early 2024.
Genesis to use Samsung's 25" AMOLED displays in its next-gen automobiles
According to reports from Korea, Hyundai Motor decided to adopt Samsung Display's 25" AMOLED displays in its next-generation Genesis car, a horizontal dashboard display.
Samsung already supplies AMOLED displays for Hyundai's Ioniq 5 (digital side mirrors), but this is the company's first design win for Genesis.
Visionox shows its latest OLED prototypes and technologies at Display Week 2023
China-based Visionox demonstrated many OLED displays and new technologies at Display Week 2023.
So first up, we have some rollable and foldable OLEDs. You can see some impressive looking such flexible OLEDs in the video above, and Visionox featured many such displays at their booth.
Sigmaintell: production of OLED smartphone displays in China to jump 40% in 2023
Most analysts seem to agree that global demand for OLED displays is set to slow down in 2023. DSCC says that revenues will decrease 7% in 2023, led by a drop in demand for OLED smartphone and TV displays. Omdia also agrees, saying that OLED fab utilization remains low.
China-based Sigmaintaell, meanwhile, is optimistic on China's own OLED industry, expecting production to jump 40% in 2023. Sigmaintell says that Chinese phone makers are increasing their adoption of OLED displays in high-end and mid-range models. The company's analysts expect over 220 million Chinese OLED panels to ship in 2023, and China's OLED market share to rise to 38%, up from 28% in 2021.

HKC to start making AMOLED displays in collaboration with JDI using its eLEAP production technology
In 2022, Japan Display (JDI) announced that it has developed a "historic breakthrough in display technology" - a new OLED deposition process which they refer to as eLEAP, that is said to be cost effective and can be used to create freeform OLEDs that are brighter, more efficient, and longer lasting compared to OLEDs produced using mask evaporation (FMM).
We now hear that China-based LCD maker HKC Corp has signed an agreement with JDI to adopt its technology for mass production of AMOLED displays. Under the agreement HKC will invest billions to build AMOLED factories in China, while JDI will provide the manufacturing expertise and technologies, including eLEAP. The plan is to begin mass production in 2025, with the first applications to be in automotive displays and wearable devices.
Omdia: small-size AMOLED display shipments down 6% in 2022
Omdia says that small-size (under 9") AMOLED display shipments dropped 6% in 2022 to 762 million units, due to lower demand for smartphones.
Samsung remains the leading AMOLED maker, with a 56% market share (by unit), down from 61% in 2021, with BOE in the second plane (12%) and LG Display in the third place (11%). The next producers by shipments are Visionox and Everdisplay.
Samsung launches a website that tells you whether your smartphone has an OLED made by SDC
Samsung Display launched a new web site, called OLED Finder, in which you can choose your phone model to see whether it uses an OLED produced by Samsung Display.
This is a marketing play by SDC, that aims to establish the superiority of Samsung's own OLED panels, over competing panels made by LGD, BOE, Visionox, etc. The website does not include all phones though that use OLED displays - for example it does not include any of Apple's iPhones.
Reports from Korea suggest that BOE is facing technical challenges as it struggles to become an OLED supplier for Apple's iPhone 15
According to reports from Korea, BOE is developing smartphone OLED displays for Apple's iPhone 15 range, but it is facing technical hurdles.
Specifically, the iPhone 15 design has a camera (and FaceID sensors) punch-hole inside the OLED, and BOE's panel suffer from light leakage from the OLED into the camera hole area.
Sony starts shipping its PlayStation VR2 OLED VR gaming headset
Sony's long-awaited second-gen VR headset, the PlayStation VR2, is finally shipping. Sony is offering the new headset for $549.99 in the US, and it is also available globally.
The PlayStation VR2 is based on dual 120fps 2000x2040 OLED displays that provide a 110-degree FOV. This is the first major VR headset based on AMOLED displays for a long time.
