The problem
Every AR/VR session on red micro-LEDs ends the same way: shrink a conventional red LED to a few micrometers and its light output collapses — blocking the ultra-high-definition, daylight-bright displays headsets need.
How it works
IntraPhoton turns Ritsumeikan University research into epi-wafers: europium-doped GaN keeps red emission efficient at micro scale, and a triple-layer stack delivers full color, so micro-displays can be fabricated directly with standard semiconductor processes at better yield and cost.
Pain points
Headset makers cannot hit retinal resolution or brightness with LCD/OLED, and the whole industry gathers at red-micro-LED conference sessions because nobody has solved the red subpixel.
Business model
Fabless foundry play: sell epi-wafers to Apple-, Meta-scale display customers instead of building panel factories — technology superiority over capital expenditure.
Challenges
Founded in October 2025 and still grant-backed (UTokyo IPC 1stRound non-equity support), with the full seed round planned only for April 2027; epi performance must survive volume manufacturing and GAFAM qualification timelines.
Funding
- Raised: none disclosed (pre-seed; 1stRound non-equity grant support).
- Valuation: MISSING.
Latest — October 2025
On 6 October 2025 IntraPhoton was founded in Shiga and selected for the 13th 1stRound cohort, launching its challenge to supply next-generation micro-LED epi-wafers to global AR/VR makers.
