OL-3A20 Fully Automatic Particle Dent Detection Machine
High-Speed Inspection for 0.96–10.1″ Displays
Engineered by Olian Automaic
- Developed by Olian Automaic, a Shenzhen-based leader in automation equipment.
- Designed for automated detection of conductive particle count, strength, distribution uniformity, and offset measurement in COG/FOG/COF applications.
- Supports display sizes from 0.96 inches (21×12 mm) to 10.1 inches (205×154 mm) with material thicknesses of 0.25–2 mm (excluding polarizer).
Core Functionality
