Seichi Tech, a specialist in semiconductor and display inspection equipment, showcased an integrated inspection solution targeting the mass production of Micro OLED and Micro LED displays at SID Display Week 2026.
Founded in 2011, Seichi Tech, officially Shenzhen SEICHI Technologies Co., Ltd., provides testing equipment and system solutions for the semiconductor and display industries. The company was listed on China’s SSE STAR Market in 2023.
Seichi Tech has approximately 1,000 employees, more than 700 of whom are technical personnel. The company also holds over 550 intellectual property rights and more than 200 invention patents.

At this exhibition, Seichi Tech highlighted its core strength: an inspection equipment portfolio that covers the entire Micro Display process. Through Wafer AOI, Wafer ATE Tester, Module PG, SLT equipment, Micro Display Burn-in systems, Near Eye Display testing equipment, high-resolution colorimeters, and luminance meters, the company presented solutions capable of supporting every stage from wafer inspection to module inspection, De-mura, Burn-in, and final NED testing.
In particular, the 127M Microscopic Detection System is designed to measure the luminance, chromaticity, and spectrum of Micro LED, Mini LED, OLED, and AR/VR displays with high resolution. Its key features include 127MP ultra-high-resolution imaging, filter wheel-based chromaticity measurement, microscope lenses for fine pixel inspection, and combined imaging and spectral calibration. Since Micro OLED and Micro LED displays have extremely small pixel sizes and strict defect judgment criteria, sub-2μm pixel detection and precise luminance and chromaticity measurement technologies are considered essential for securing mass production yield.
Seichi Tech also emphasized automation and mass production readiness. Its Wafer AOI inspects images while DIEs are powered on, while its SLT equipment performs De-mura, appearance inspection, luminance AOI, and automatic grading for packaged Micro LED/OLED modules. The Micro Display Burn-in system integrates automatic alignment, pressing, carrier heating, abnormality detection, and MES connectivity to support real mass production environments.
Seichi Tech’s SID 2026 exhibition demonstrates that the company is expanding its position beyond that of a simple inspection equipment supplier, emerging as an integrated test solution provider capable of addressing mass production bottlenecks in Micro OLED and Micro LED displays. As the XR, AR glasses, and Near Eye Display markets move toward commercialization, the importance of precision inspection, calibration, and Burn-in equipment is expected to increase further.
