Innolux showed a 106″ as well as rigid and flexible microLED display modules.
106-Inch MicroLED Display
- Built from 96 tiles, each 12.3 inches diagonally.
- Resolution per tile: 480 × 180 pixels.
- MicroLED size: 20 × 40 microns.
- Color conversion approach:
- All blue microLEDs.
- Inkjet-printed red and green quantum dots for color conversion.
- Brightness: 700 nits, but appears much brighter thanks to excellent color saturation.
- Estimated color gamut: Likely close to P3.
- Surface treatment: Anti-glare and anti-reflection.
- Visual impression: One of the best-looking microLEDs on the show floor.
Manufacturing and Roadmap
- Ready for mass production this year on a Gen 3.5 LTPS glass line.
- Plans to move to Gen 6 by 2026 for higher scalability.
- Mass transfer via stamping process.
- Assembly: Currently semi-automated, with full automation targeted for Q4 this year.
- Blue wafers sourced externally; quantum dot deposition done in-house via inkjet printing.
Performance and Reliability
- Special processes implemented to extend lifetime, addressing challenges from high flux near quantum dots.
- Heat output: Minimal, even up close.
- Simplified design:
- Single material system (blue microLEDs) reduces complexity.
- Higher yield and better thermal stability compared to RGB microLED systems.
Additional Demonstrations
- RGB microLED panels for broader applications.
- Flexible microLED display:
- Likely built on polyimide substrate.
- Targeted for automotive applications.
- Rigid version for IT applications.
Key Takeaways
Innolux is pushing microLED technology forward with:
- Large-format, high-quality displays.
- Efficient color conversion using quantum dots.
- A clear roadmap to mass production and automation.
- Versatile designs for automotive and IT markets.
