Most companies in the display industry believe that microLED is the leading next-generation display technology, that will be able to replace LCDs and OLEDs in many applications. MicroLEDs offers many advantages – both technical such as higher durability and higher brightness and efficiency, but also in unique production processes and models.
The two leading Taiwanese display makers, AUO and Innolux, have been pushing forward aggressively with their microLED projects. This is mainly due to the fact that both companies do not have any real OLED projects, which means that it is easier for them to develop microLEDs as their next-generation technology. MicroLEDs could provide a way for both AUO and Innolux to “leapfrog” over OLED technology.
Against this backdrop, a potential merger between AUO and Innolux presents an intriguing strategic opportunity. By combining their technological expertise, manufacturing capabilities, and financial resources, a merged entity could potentially accelerate microLED development, and perhaps also receiving meaningful financial support from the Taiwanese government, as such as move could strengthen Taiwan's position in the global display industry.
Note that we have no indications that such a merger is even considered by the two companies, but we feel this is a fascinating topic that should be explored and is supported by several strong arguments.
Current market positions and capabilities
AUO is one of the world’s leading display makers, with a diverse portfolio of display technologies – including LCDs, LTPS backplanes, touch solutions, ePaper – and of course microLEDs. AUO has over 40,000 employees and generated over $9.3 billion in revenues in 2024. The company was actually the world’s first AMOLED producer in 2006, but it never managed to scale up its AMOLED production to compete with the world’s leading OLED makers.
AUO is likely to be the world’s leading microLED display developer. The company is already commercially producing microLED wearable displays (which will likely reach the market later this year), at its 1-Gen production line, and is also building its 4.5-Gen production line, in collaboration with PlayNitride. The new line will dramatically increase the company’s microLED capacity, enabling it to produce automotive displays - it already announced its first automotive display design win (Sony Honda’s AFEELA 1). AUO is focusing on wearable, automotive and large-area microLED displays.
Innolux, Taiwan’s second major display maker, has over 55,000 employees and is mainly focused on LCD displays. The company generated revenues of $6.58 billion in 2024, or 70% of AUO’s revenues. Similarly to AUO, Innolux had an active AMOLED project and even started mass producing displays many years ago, but never managed to compete with the world’s leading producers. Recently it announced a partnership with JDI to bring automotive eLEAP AMOLEDs to market.
Innolux has an active microLED project, focusing on QDCC displays targeting signage, wearables and automotive applications.
Strategic Rationale for a Merger
We can identify several reasons for these two companies to merge – to create a consolidated Taiwanese display champion, to accelerate microLED development and to enable financial synergy and increase investment capacity.
The display industry is highly competitive, with significant pressure from South Korean and Chinese manufacturers who have invested heavily in advanced display technologies, particularly OLED technology. A merger between AUO and Innolux would create a more consolidated Taiwanese display champion better positioned to compete on a global scale through enhanced economies of scale, reduced redundancies, and combined technological expertise.
MicroLED technology represents a significant opportunity for both AUO and Innolux to differentiate their offerings from OLED displays. The microLED industry, however, remains in a preliminary stage, with significant challenges in manufacturing efficiency, yield rates, and cost reduction. By combining their research and development resources, AUO and Innolux could potentially accelerate the timeline for bringing commercially viable microLED displays to market, especially in high-potential segments like automotive displays, AR/VR microdisplays, and wearables.
The two companies have both developed many microLED technologies, and have both focused on automotive, wearable and signage displays. It seems as if AUO has a more advanced project, but it is likely that it could benefit from the technologies and expertise developed at Innolux, especially in the areas of automotive, transparent and large-area signage applications.
Finally, a merger could potentially create financial synergies that would be particularly valuable for scaling microLED technology when the technology is ready for mass production. AUO's recent return to profitability, combined with Innolux's slightly growing revenues, could provide a stronger financial foundation for the substantial investments required to commercialize microLED displays. The combined entity would likely have greater access to capital markets and improved ability to fund the research, development, and manufacturing capacity needed to compete with OLED manufacturers. In addition, it could be argued that the Taiwanese government will support such a merger in a bid to secure the future of its local large display industry.
Challenges and Considerations
As we said, a merger between AUO and Innolux would significantly consolidate Taiwan's display industry – but this could potentially raise antitrust concerns. Regulators would need to evaluate whether the combined entity would create anti-competitive effects in specific display market segments, particularly for TFT-LCD panels where both companies have substantial market share. However both companies, even combined, do not hold a large market share in the display industry, which is dominated by Chinese and Korea producers, especially Samsung Display and BOE.
Merging two large organizations with different corporate cultures, management structures, and operational systems always presents significant challenges. The combined workforce of nearly 100,000 employees would require careful integration to maintain productivity and retain key talent, particularly in R&D teams working on microLED technology, to make sure these teams remain on-board and committed to common goals.
The display industry suffers from commodity pricing and low margins. AUO recently returned to profitability, but Innolux still posts quarterly losses, and this would need to be addressed in any merger structure. The financial arrangements would require careful consideration to ensure the combined entity maintains sufficient liquidity while continuing to invest in next-generation display technologies like microLED.
Another challenge and detriment to a potential merger lies in the technological path chosen by the two companies. AUO is focused on a direct RGB architecture, while Innolux on a color-conversion based architecture (QDCC: blue LEDs with QD color conversion). While both architectures share many technologies and processes, this could prove to a stumbling block for a merger between the two companies. On the other hand, this could also strengthen the rational of a merger, as it could lead the combined entity to continue and develop both platforms, as it is not clear yet which will be more suitable for mass production, and it could be that different applications will benefit from different architectures. As one of the benefits of microLED display lies in easier customization and de-coupling of production, a combined entity may choose to retain the two different architecture paths.
