Apple’s Impact on Micro LED’s Path and the Approaching Era of Game-Changing Applications

When Apple unveiled its inaugural wearable device, the Vision Pro, in June this year, CEO Tim Cook remarked, “Apple Vision Pro introduces us to spatial computing.”

The era of spatial computing entails redefining how users interact with digital content within the context of the real world. Apple’s ambition extends beyond mere immersive entertainment, aiming to seamlessly integrate personal computers and smartphones into everyday life and work scenarios, replicating the success it achieved in personal and mobile computing.

The launch of the Vision Pro has once again thrust new display technologies into the industry spotlight. Although the Vision Pro employs Micro OLED, the potential to achieve a portable, outdoor-capable mixed-reality headset rests on Micro LED, seen as the most promising option.

“Micro LED demonstrates balanced performance beyond average levels in terms of brightness, energy consumption, pixel density (Pixel per Inch, PPI), and optical module size,” noted Eric Chiou, Senior Research Vice President at TrendForce. He further emphasized Micro LED’s potential in the development of AR devices, stating, “This also explains why Meta, Google, and MIT are continuously evaluating and assisting in the development of Micro LED technology.”

The application potential of Micro LED in AR devices is evident from the number of companies investing in its development.

In the first half of 2023 alone, six companies—Raysolve, Porotech, Sitan, Kopin, GoerOptics, JBD—announced progress in the development of Micro LED micro-display products. Additionally, two AR glasses manufacturers, Rayneo Innovation and Nubia, unveiled products featuring Micro LED chips.

Certainly, Micro LED’s implementation is not confined to AR eyewear; it is making inroads into the realm of wearables, particularly in the form of smartwatches. Soon, consumers will find the first commercially available watch featuring a Micro LED screen on the market. Tag Heuer, a luxury watch brand, is leading the way with support from AU Optronics for Micro LED panels.

Anticipation mounts for an Apple Watch featuring a Micro LED screen, with rumors circulating consistently. According to earlier information from TrendForce, the release of the Micro LED version of the Apple Watch, originally projected for the second half of 2025, has been delayed to the first quarter of 2026. Initial reports suggested the supply of Micro LED chips would come from Epistar and Osram and that Apple would handle mass transfer at its Longtan facility. Recent reports, however, suggest that Apple might entrust mass transfer and subsequent work to its long-term collaborator, LG Display (LGD).

It’s rumored that LGD has visited Apple’s Longtan facility, indicating a potential handover of equipment to LGD, facilitating smooth mass transfer and back-end processes. Despite shifts in the supply chain, this alteration underscores Apple’s commitment to advancing the Micro LED version of the watch into mass production, with wearables continuing to play a pivotal role in the practical implementation of Micro LED.

The industry’s technological development and investment in wearables, particularly watches and AR glasses, demonstrate a shift towards small-sized sectors represented by headsets and wearables. This indicates that Micro LED is edging closer to large-scale commercialization and breakthrough applications.

Regarding the commercial development of Micro LED, the launch of large-sized products remains a critical indicator. Korean giants Samsung and LGD are pivotal players in this regard. Following Samsung’s introduction of the high-end 110-inch Micro LED TV, LGD’s plans to release a 136-inch Micro LED TV in 2024 have surfaced. Factoring in Samsung’s and LGD’s entries, a total of five companies, including AUO, BOE, and SmartKem, have announced developments in Micro LED display technology in 2023.

Considering the market trends mentioned above, based on TrendForce’s projections, the production value of Micro LED chips is expected to reach $27 million in 2023, showing a 92% annual growth. Looking ahead, driven by the expansion of current application shipments and the introduction of new use cases, the estimated chip production value is set to hit $580 million by 2027. This anticipates a compound annual growth rate of 136% from 2022 to 2027.
