# Lumiode, Inc.

> Lumiode is a New York-based fabless semiconductor startup building truly-monolithic micro-LED microdisplays. By depositing low-temperature polycrystalline silicon (LTPS) thin-film-transistor backplanes directly onto LED epiwafers - skipping the wafer-bonding step used by most rivals - Lumiode produces ultra-high-brightness, low-power, small-form-factor displays aimed at augmented reality, head-up displays and projection. Spun out of Columbia University in 2012 and led by co-founder and acting CEO Ioannis (John) Kymissis, the company raised roughly $16 million in venture funding before agreeing in December 2025 to be acquired by Taiwan's PlayNitride.

- **Founded:** 2012
- **Headquarters:** New York, New York, United States
- **Founders:** Ioannis (John) Kymissis (Co-founder & Acting CEO), Vincent Lee (Co-founder), John Sarik (Co-founder), Brian Tull (Co-founder)
- **Team size:** ~5 employees
- **Products:** Monolithic micro-LED microdisplay, LTPS-on-epiwafer backplane process, High-brightness display modules for AR/HUD
- **Notable:** Developed a truly-monolithic micro-LED microdisplay by depositing LTPS backplanes directly on LED epiwafers, avoiding wafer bonding., Demonstrated prototype brightness up to ~1,000,000 nits, with a stated path toward over 10 million nits., Raised roughly $16 million in total venture funding from investors including IP Group, Applied Ventures and M Ventures.

## Products & services

- **Monolithic micro-LED microdisplay** — Truly-monolithic microdisplay made by depositing LTPS thin-film-transistor backplanes directly onto LED epiwafers, avoiding wafer bonding and enabling ultra-high brightness in a small form factor.
- **LTPS-on-epiwafer backplane process** — A wafer-level manufacturing process integrating TFT backplanes with micro-LED arrays; licensed/integrated into partner manufacturing lines such as STRATACACHE's Oregon facility.
- **High-brightness display modules for AR/HUD** — Compact, low-power display solutions targeting AR/MR eyewear, automotive head-up displays and projection applications, with demonstrated brightness up to ~1,000,000 nits.
