Fast and eco-friendly process and system technology to produce highly flexible metal (transparent) electrode pattern with simple 3 stages (coating → selective light radiation → wiping)

 

Client / Market

• Deformable light & display, Smart window, Flexible transparent LED signage, Flexible heater, Flexible sensor

 

Necessity of this Technology

• Requiring expensive infrastructure such as exposure tool
• Complex patterning process, large amount of chemical waste (PR/etching solution/ developing solution, etc.) and difficulty to apply fast and scalable (roll-to-roll) process
• Difficult to use metal materials that can easily be oxidized (generally requires vacuum condition or nitrogen or argon gas atmosphere)
• Issues regarding high surface roughness, low adhesion on the substrate, low flexibility

 

Technical Differentiation

• This system and process can produce highly flexible (transparent) electrode patterns with high-speed and eco-friendly simple 3 stages without expensive facilities.
• High adhesion on the substrate, low surface roughness can be developed and metal vulnerable to oxidization in the air can be available
