According to research conducted by TrendForce, the much-anticipated Micro LED version of the Apple Watch is facing yet another delay and is now expected to be launched in the first quarter of 2026. The primary reason behind this delay is believed to be the need for reconfiguring the production supply chain.

Previously, industry speculations suggested that Apple would take charge of the core production process, particularly the massive transfer of Micro LED technology. However, recent industry research by TrendForce indicate that LG Display (LGD) might now take over this crucial aspect of the production process.

The critical process involved in the production of the Micro LED version of the Apple Watch, especially the massive transfer of Micro LED technology, has been a point of interest in the industry. It was widely speculated that Apple would handle this key engineering either at its Cupertino headquarters in the United States or potentially transfer the production to its facility in Longtan, Taiwan, for the essential massive transfer of the technology.

TrendForce understands that Apple’s decision to undertake the crucial engineering process in either the United States or Taiwan reflects their intent to have complete control over the core manufacturing process during the initial production phase. However, this approach also introduces complexities in terms of logistics and supply chain management, as the chips are set to be manufactured in Malaysia, the backplates in South Korea, and the final assembly by system integrators in China or Vietnam.

As a result, recent industry research by TrendForce indicate that Apple has finalized LGD as its primary collaborator for Micro LED production. This means that LGD will now be responsible for the critical massive transfer process. In addition to providing its own equipment and technical support, Apple is also expected to invest in LGD’s related equipment procurement to ensure a smooth transition and expedited progress in the Micro LED production pipeline.

For more information and details about the Micro LED industry, TrendForce will hold the “2023 LED Forum” on September 5th (Tuesday) from 9:30 am to 5:00 pm at the NTUH International Convention Center. The seminar has invited TrendForce’s Senior Research Vice President, Eric Chiou, as well as representatives from various industries such as Mojo Vision, ITRI, Lumus, Unikorn, Porotech, Nitride Semiconductor, Tohoku University, Coherent, InZiv, AUO, and Tianma to share the progress and related applications of Micro LED technology.

Apple has finally launched the Vision Pro, an MR device equipped with Micro OLED, but the debut of the Apple Watch with Micro LED panels has been repeatedly delayed. According to a report from TechNews, industry insiders revealed that the production timeline for the Micro LED Apple Watch has been pushed back once again, from the second quarter of 2025 to the first quarter of 2026.

Over the past decade, Apple has invested at least $1 billion in developing Micro LED panels, aiming to reduce reliance on Samsung and strengthen control over critical component supplies. Once in mass production, Apple intends to execute the crucial “mass transfer” process on its own. This highlights Apple’s cautious approach in researching and developing Micro LED technology, which is still in the sample phase due to challenging production techniques and higher manufacturing costs.

In the Micro LED project, Apple has partnered with ams Osram for the development of Micro LED components, collaborated with LG Display for backplate production, and enlisted TSMC to manufacture 12-inch silicon wafers. Initially, Micro LED technology will be introduced in the Apple Watch Ultra model before gradually expanding to other product lines such as iPad and MacBook, with the ultimate plan of incorporating it into the iPhone.

Currently, the Apple Watch utilizes OLED technology, which has been in use since the launch of the first Apple Watch model in 2015. In comparison to OLED screens, Micro LED displays offer higher brightness and overcome issues such as screen aging and differential aging, making them a promising advancement.

With the release of Apple’s Vision Pro, its Micro OLED display technology has caught the attention of more people. In fact, global Micro OLED display manufacturers have been working in this field for many years. In recent years, Chinese manufacturers have been particularly active in this area. TrendForce has compiled the recent global manufacturers’ product and technological advancements in this article.

TrendForce’s investigation into the supply chain reveals that Apple plans to upgrade the PCB materials in its new iPhone models in 2024. The current copper-clad laminate (CCL) will be partially replaced with resin-coated copper (RCC), aiming to reduce the size and thickness of the mainboard. This upgrade is expected to enhance electronic signal transmission efficiency, reduce energy consumption, and save internal space, providing more room for increased battery capacity.

Apple first introduced the substrate-like PCB (SLP) with the launch of the iPhone X in 2017. SLP offers advantages over conventional high-density interconnect (HDI) PCBs by reducing line width and spacing, optimizing PCB area, and increasing battery space. This design has remained unchanged since its introduction. However, recent discussions within the supply chain indicate that there are plans to introduce RCC materials in the second half of 2024 for the upcoming iPhones, marking an upgrade after a seven-year gap.

The main difference between RCC and traditional CCL lies in their structure. RCC eliminates one layer of fiberglass cloth, significantly reducing the overall thickness of the PCB. It also simplifies the manufacturing process and improves the laser drilling yield. In terms of component performance, RCC allows for further reduction in line width and spacing of circuit wiring based on SLP, reducing the spacing between various passive and active components on the board. It even enables the embedding of some passive components, thereby saving space required for surface mount technology (SMT) processes. All these upgrades contribute to greater power efficiency and improved performance in end devices.

Considering the similarities between RCC and ABF substrates in terms of the manufacturing process, the most likely supplier for RCC is the Japanese company Ajinomoto. If Apple successfully replaces some layers with RCC in 2024, it may impact the demand for existing CCL, particularly affecting the CCL supplier, Elite Material (EMC). It is anticipated that EMC’s RCC product may require 1-2 more years of research and development before it has a chance to be completed.

considering factors such as pricing and the absence of certain essential features, TrendForce anticipates a modest shipment volume of approximately 200,000 units for Apple Vision Pro in 2024. The market’s response will heavily depend on the subsequent introduction of consumer-oriented Apple Vision models and the ability of Apple to offer enticing everyday functionalities that will drive the rapid growth of the AR market as a whole.

VR/AR shipments are expected to drop to 7.45 million in 2023

In the meantime, TrendForce forecasts a global downturn in AR and VR device shipments for 2023, predicting a shipment total of roughly 7.45 million units—an 18.2% YoY decrease. VR devices are expected to shoulder the majority of this decline, with projected shipments hovering around 6.67 million units.

Conversely, shipments of AR devices are expected to remain stable, with projected shipments exceeding 780,000 units. While Apple’s latest offerings could stimulate some demand, the high price tags attached to these units continue to pose a significant barrier to broader market growth.

TrendForce posits that the trajectory of the VR and AR device market may encounter certain limitations between 2023 and 2025. While affordable VR devices could pique the interest of mainstream consumers, the prospect of minimal profitability might dissuade manufacturers from substantial investment in the VR market in the immediate future. A shift towards AR devices and their corresponding applications seems more probable.

Nevertheless, the expansion of the AR device market hinges on a broader acceptance of consumer applications. Therefore, TrendForce anticipates that a significant rise in the VR and AR market, potentially nearing a 40% annual increase in shipments, might not be realized until 2025.
