Core technology for continuous production of flexible OLED based on roll-to-roll method; roll-to-roll vacuum evaporation system technology for creating multiple thin films of organic, inorganic, metal material with pattern suitable for OLED panel

Client / Market

• Flexible OLED lighting (indoor lighting, interior, automobile, entertainment, etc.)
• Flexible OLED display (signage, wearable, mobile phone, etc.)

 

Necessity of this Technology

• The current technology for flexible OLED production using glass carrier forms a film on top of glass through Pl (polyimide) coating or heat treatment or adhere a separate film onto the glass and use the existing glass process to manufacture OLED. Additional processes and expensive devices are required for flexible OLED separation using LLO (laser lift off).
• If the film plate is handled directly with the roll-to-roll method for continuous process, it can achieve significant cost reduction.
• In particular, productivity can improve largely if this technology of roll-to-rollbased continuous method for OLED production instead of existing cluster method consisting of multiple devices.

 

Technical Differentiation

• Directly process on the film roll without glass carrier
• Single chamber roll-to-roll composition instead of existing cluster type vacuum evaporation system
• Real-time fine pattern mask align/mask gap control technology is applied, and micro pattern can be evaporated.
