Toba has been spin-off at the FDRC (Flexible Display Research Center) of Konkuk University for 30 years. Since then, it has acquired 22 R2R technology patents and 14 commercial licenses. have. Toba develops and markets the most important high precision tension and resistor controller in R2R system operation and control. Tension control can control ± 2-5% of operation tension and ± 15μm resistor error. Major products include roll-to-roll platform for R2R coating, calendering, printing, dryer, plating, sputtering and inkjet, and have ability and experience in designing, manufacturing and programming including ± 15μm resistor control and simulation capability. It provides an integrated solution for R2R production.
