About Me

MicroLED engineer by day, AI tinkerer by night. I lead MicroLED systems architecture at Japan's top LED semiconductor company — FPGA, ASIC, full-stack from spec to production test. My home lab hosts a Raspberry Pi robot arm, ESP32 smart home gadgets, and a voice-recognition AI that sometimes listens. I think about technology through the lens of industry cycles and commercial viability — great engineering should answer 'can this sell, and is it worth building?' Fluent in Chinese, Japanese, English and Korean. Motto: if you can think it, AI can build it 10× faster.

Background

Currently Tech Lead at Japan's leading LED semiconductor company. Driving system architecture and production test infrastructure for ASIC-integrated MicroLED products — from requirements definition to FPGA-based EOL test. Trilingual technical communication (Chinese/Japanese/English) enables cross-border ASIC co-development with partners like Infineon, and direct technical enablement for China Tier 1 customers. Beyond engineering, I spend time studying industry cycles, technology commercialization, and long-term value creation. Conviction: technology divorced from business context is just a hobby.

MicroLED Technology

Exploring the core of next-gen display and communication technology

Core Technology

MicroLED size <100μm, self-emissive display, no backlight needed. EQE (External Quantum Efficiency) improvement is the core challenge, with GaN as the mainstream material. Offers ultra-high contrast, extremely low power consumption and nanosecond response time.

AR Applications

Ultra-high brightness (>10,000 nit), ideal for outdoor AR scenarios. Combined with waveguide systems for near-eye displays, it's the core emitter for next-generation AR glasses.

Optical Interconnect

High-speed modulation characteristics (>Gbps), based on Microsoft MOSAIC architecture, offering a new solution for short-distance optical interconnects in data centers with parallel optical transmission capability.

Bonding & Packaging

Cu-Cu hybrid bonding technology for wafer-level integration. Heterogeneous integration with CMOS driver backplanes is key to mass production, breaking through yield and cost bottlenecks.

Industry Status

Apple, Samsung, Sony and other giants are actively deploying in the MicroLED supply chain. First consumer AR glasses expected to enter mass production in 2026-2027.

Vision

Using technical writing to lower the barrier to MicroLED and photonic semiconductor knowledge. Exploring AI Agent-driven engineering automation, tracking open-source EDA toolchains like gdsfactory and OpenROAD. The goal: bridge technical depth, commercialization insight, and long-term thinking. Feel free to reach out via GitHub or Email.
