MicroLED technology is a next-generation emissive display technology that promises highly efficient and bright displays that offer superior image quality with infinite contrast and a wide color gamut.

Apple is one of the leading MicroLED developers. Apple acquired Micro-LED developer LuxVue back in 2014- as the company is considering this next-generation display technology as suitable for its various products. Since the LuxVue acquisition, Apple accelerated its MicroLED R&D project and is developing solutions for smartwatches, AR and other display types.

and has not updated on the technology since, but several reports suggested that Apple has an R&D Micro-LED team in Taiwan and some analysts estimated that Apple actually aims to start low-volume Micro-LED production by the end of 2017 with mass production of smart watch displays beginning as soon as 2018.

For several years, we have heard reports that Apple is aiming to deploy MicroLED displays in future smartwatch projects. The latest Watch devices use LTPO OLED displays, but a microLED display will enable Apple to extend the Watch battery life and increase its brightness. According to reports Apple is collaborating with several companies, mainly in Taiwan, and is actively involved with microLED R&D and production plans.

Apple, AUO and Epistar to establish a $334 million mini-LED and micro-LED production fab in Taiwan?

According to a report from Taiwan's Economic Daily news, a new mini-LED and micro-LED display factory is under planning in Taiwan's Hsinchu Science Park. The new fab is built by Apple (who will invest $334 million) in collaboration with AU Optronics and Epistar.

According to the report, the Science Park Administartion approved Apple, Auo and Epistar's plan on February 18. The new fab will act as an expansion of Apple's existing display center in Taiwan.

Yole Developpement: the rate of MicroLED patent filing is rising exponentially

Yole Developpement reports that about 5,500 microLED patents (2,500 patent families) have been filed, by more than 350 organizations. The rate of patent filing is growing exponentially - 40% of the patents were filed in 2019.

Patent publication timeline (2001-2019, Yole Developpement)

According to Yole, the recent patent filing shows that the industry is moving from prototypes to commercial consumer displays. Other notable new finding include that startup companies are a major innovation force, Apple is slowing down with its IP (but this could mean that the company is now focused on commercialization), and Samsung pursues multiple development tracks. BOE is another strong microLED IP player, with almost 150 patent familiies filed in 2019.

Yole: microLED shipments to reach over 125 million panels by 2027

Market analysts at Yole Developpement say that microLED shipments will reach over 125 million panels by 2027. In their aggressive scenario, shipments will reach almost 450 million.

Yole says that microLED technologies are advancing rapidly - and on all fronts, but there are still many challenges to overcome before mass production arrives. MicroLED makes a strong case for the AR, smartwatch and automotive market. For the smartphones and TV markets it is less clear whether MicroLEDs could succeed.

Will PlayNitride and RiTDisplay supply Apple with MicroLED displays for future Watch devices?

According to Taiwan's Economic News Daily, PlayNitride and RiTDisplay are in talks with Apple to supply microLED displays for Apple's next-generation Watch wearable.

These are just rumors at this stage, but END says that PlayNitride confirms it is in talks with US customers regarding a 3" full-color Micro-LED display. This interesting as this is not a display we are used to see in most mobile devices - wearables are usually limited to around 1.5" while smartphones today start at around 6".

We talk Micro-LED technology and market with Yole Développement

Market research firm Yole Développement has been following the Micro-LED market for some years with some very interesting insights and forecasts.

Yole's technology & market analyst Zine Bouhamri was kind enough to discuss Yole's Micro-LED views with us. Mr. Zine is is a member of the Photonics, Sensing & Display division at Yole and he's deeply involved in the business development of the Displays unit activities.

n-Tech sees a very bright future for Micro-LED displays, starting in 2019

n-tech Research says that the Micro-LED market will emerge in 2019, with sales reaching $2.7 billion. The market will grow very quickly to reach over $70 billion in 2027.

MicroLED display market forecast (2018-2027, n-Tech)

n-Tech says that the immediate markets for Micro-LED displays will be near-eye displays (AR/VR), automotive HUDs and projectors - as these will benefit mostly from the small size, low weight, high brightness and high resolution of Micro-LED displays. Wearables (smartwatches) is another lucrative market (n-Tech sees $1.6 billion in smartwatch Micro-LED display sales in 2022).

PlayNitride to setup a $17 million Micro-LED production facility, reportedly in talks with Apple towards Micro-LED collaboration

Digitimes reports that Taiwan's Ministry of Science and Technology approved PlayNitride's application to setup a NT$500 million (US$17 million) production facility at Hsinchu Science Park.

PlayNitride aims to produce micro LEDs, display modules and panels at its new facility at Hsinchu. According to Digitimes, Apple is in preliminary talks with PlayNitride towards a possible Micro-LED technology cooperation.

Digitimes: Apple is collaborating with TSMC on Wearable/VR/laptop Micro-LED displays, first displays will enter production by early 2019

Earlier this month Bloomberg reported that Apple is progressing with its Micro-LED development project, and has already managed to produce promising display samples. Now Taiwan's Digitimes reports that Apple is collaborating with Taiwan Semiconductor Manufacturing Company (TSMC) towards mass production of Micro-LED panels.

Apple and TSMC are focusing on small-sized micro-LEDs on silicon based backplanes, targeting both wearable devices and AR applications. The Micro-LED microdisplays for AR applications will be around 0.7-0.8 inch in size, while the wearable panels will be larger at 1.3-1.4 inch.
