Wearable computers, also called ‘wearables’, are technological devices that can be worn as clothing or accessories. Some wearables are based on relatively simple technology, similar to a scaled-down desktop computer, but some involve innovative technologies. Wearables include different products, such as fitness bands, wearable headsets, smart watches, healthcare monitoring and displays embedded in textiles.
The wearables market is diverse, but faces similar challenges like minimizing size and weight of components, deciding on optimal display location, choosing suitable services and applications to provide and balancing cost-to-price ratios.
OLED is a light-emitting diode built from thin films of organic electroluminescent material sandwiched between electrodes. OLED devices emit light when current is run through them, and are used to develop display and lighting panels. OLED screens are thinner, lighter, more efficient and offer better performance and color quality than other existing technologies.
OLEDs divide into 2 groups: AMOLEDs and PMOLEDs, which refers to how the screen is addressed by the electronics of the device. Simple wearables such as fitness bands usually adopt PMOLED displays, while smartwatches and VR headsets opt for AMOLEDs. Here's more information about AMOLED vs. PMOLED technologies.
OLED displays are very popular in the wearables market - thanks to the great image quality, the low power consumption and to the design possibilities enabled by flexible OLEDs. Most high-end smartwatches, fitness bands and headsets adopt OLED displays, including both Apple's Samsung's smartwatches. Here's our comprehensive list of wearable devices that use OLED displays.
Latest Wearable OLED news
The MicroLED Industry Association published today its first white paper, an application note that discusses the feasibility of microLED wearable displays soon, focusing on an LED cost analysis to see if such a display actually makes sense for smartwatch makers by 2024.
The white paper can be downloaded over at the MicroLED Association's website.
Researchers from Korea's KAIST institute developed a fabric-based wearable patch that uses a blue OLED device to treat jaundice in newborns.
The researchers say that phototherapy is the most widely used treatment for neonatal jaundice, as it is a safe and effective to transform the bilirubin that is accumulated in the body and release it. When the bilirubin concentration is too high, the doctors treat newborns with blue light in an incubator. The new device can be used to treat high levels of bilirubin, without the need for an incubator.

This is a great guide if you're considering to adopt OLED microdisplays in your product, if you're looking to learn more about next-generation micro-LEDs and if you want to understand this industry better.
Samsung announced two new foldable phones, and new wearable devices. First up is the Galaxy Z Fold4 which sports a 7.6" foldable 120Hz 1200 nits 1812x2176 Dynamic AMOLED and a 6.2" 120Hz 904x2316 AMOLED 2X cover display.
The Galaxy Z Flip4, the company's clamshell device,features a 6.7-inch 120Hz 1200nits 1080x2640 foldable Dynamic AMOLED 2X display and a small secondary 1.9" 260x512 Super AMOLED display. Both phones will ship on August 25, starting at $2,000 for the Fold4 and $1200 for the Flip4.
There's a new report that suggests that Samsung Electronics is looking into adopting OLED displays made by BOE for its Galaxy Watch 6 smartwatch (which will be released in 2023).
The same report also suggests that Samsung Electronics is looking into adopting BOE OLEDs in premium smartphones.
Today we published a new edition of our OLED and MicroLED Microdisplays Market Report, with all the latest information. The new edition includes more than 10 new updates, new companies, new datasheets and revamped sections on APS, Mojo vision, Porotech, PlayNitride and more.

Tianma announced that it has successfully commercialized in-cell touch AMOLED displays, and it is now starting to mass produce the first such display to a customer, a well-known smartwatch maker that will ship the product in Q3 2022, globally.
Tianma explains that by adopting the in-cell structure, it has managed to reduce the total screen thickness by 20%, compared to its current on-cell technology. The new AMOLED display is also lighter.
DSCC says that global OLED revenues in Q1 2022 were around $9.5 billion, the same as in Q1 2021, even though unit shipments declined 4%.
Smartphone remained the leading OLED application, with a 79% revenue share, even though shipments decreased 8% (and revenues decreased 3%). The second largest application by shipments is wearables (16% in Q1 2022 by shipments and in 6% market share by revenues).
Researchers from the Korea Advanced Institute of Science and Technology (KAIST) developed a white OLED device that can be deposited on thin fabrics. The researchers say that this is the world's first such device, as previous white OLEDs, made using a tandem structure, could not be bent on fibers.
For the new device, the researchers developed a single white light-emitting layer. The brightness of the device is up to 700 nits, with an efficiency of 10 candelas per ampere.
In recent years we have seen AMOLED displays fall out of favor in the VR market, as most devices have opted for high-end LCDs, due to the better image definition, mostly. According to DSCC, this is set to change next year (in 2023).
Sony has already adopted high density (>800PPI) AMOLED displays in the Playstation VR2, DSCC says that this trend will continue. DSCC also sees OLED microdisplays finally entering the VR market in 2023, with around 15 million such displays shipped in this market by 2024.
