From display technology to AI infrastructure: the new role of microLED

The display industry is always waiting for its next big thing. For the past few years, microLED TVs have often been the talk of the show at SID Display Week. However, this year, their presence was muted. Instead, TCL pushed its Inkjet-Printed OLED for a wide range of applications, including smartphones and IT and Visionox had its VIP lithographic process; but the real stars of the show were probably 4 primary miniLED backlights, implemented with either RGBC miniLEDs or with white miniLEDs combined with 4 primary color filters (and possibly an extra Cyan QD). They were the flagships in most booths (BOE), and the good news is that actual products are now available in the market.

SID Display Week 2026 highlighted a major shift in the display industry. While miniLED is gaining traction in premium TVs, microLED is moving into its first commercial applications, from AR glasses and automotive HUDs to transparent displays and AI data center optical I/O. In this article, Yole Group’s analyst, Raphaël Mermet-Lyaudoz, shares the key takeaways from the event and the technologies shaping the future display ecosystem.

Beyond the TV battlefield, one thing is now very clear: the microLED path looks very different depending on whether we talk about TFT or Si CMOS backplanes.

On the TFT side, the narrative has shifted from huge expectations to more concrete use cases. The most compelling ones today appear to be automotive HUDs and transparent displays, the latter most likely for B2B applications like smart retail.

For MicroLED-on-Silicon (LEDoS), prime time feels close as the augmented reality market ignites and OEM pull meets industry readiness. With the market responding positively to audio glasses like the Ray-Ban Meta, Jason Hartlove (Meta) used the business conference to reinforce his bullish view on AR and called on the industry to join forces to make his 100/4/100 wish come true: 100 million display systems per year, at $100 each (including display engine and relay optics).

On the technology side, MicroLED display engines are becoming increasingly smaller (0.16  cc for the next-gen prism-based RGB projector from Hongshi). In parallel, single-panel color-conversion-free RGB solutions are emerging, such as Aledia’s nanowire-based approach and Innovision’s vertically stacked one. Raysolve showed a 0.18 cc color-converted single-panel solution. PlayNitride also showed color-converted 0.18-inch panels in a 0.4 cc projector. The likely path forward is for microLED to be adopted first in a 3-panel/prism-based configuration before transitioning to single-panel as the technology matures.
