Basics

Equipment name: Small-ELVESS

Features

This equipment is ideal for basic R&D and small-volume production of OLED displays. All processes, from O2 plasma cleaning to deposition and encapsulation, are performed in a single system. It is possible to create high-performance OLED devices because there is no contact with the atmosphere. Highly reproducible processing makes efficient device process development possible, all the way up to the transition to mass production.
