[Reference] Process simplification

Compared to other electronic paper technologies, NDIS's CLC technology is a significantly simpler process. Lower manufacturing cost and Easy to enlarge size.

Simple printing type CLC manufacturing process

  • Simple process
    - Coating, Lamination, UV exposure
    - Process at room temperature and atmospheric pressure
  • Easy to maximize
  • Low manufacturing process cost
  • Easy to use plastic substrate
  • Suitable for high productivity by roll-to-roll process

[Reference] High-efficiency color implementation technology

Single material use for R, G, B coor implementation

  • Photo-reactive chiral dopant added to liquid crystal
    - Change in chiral pitch according to UV dose → Color change
    - In-house material development
  • Form a single liquid crystal layer with a single material, then from R, G, B color for each pixel by mask UV irradiation
  • Innovative simple process enables full color without color filter

High reflectance CLC

  • Full-color implementation with R, G, B panel lamination
    -  High reflectivity color implementation
    -  Other displays can not be laminated in principle
  •   No problem when using thin plastic substrate
  •   Improvement of color reproduction rate by controlling alignment of cholesteric liquid crystal (CG> 20%)

Acquired "New technology certification"

In 2011, NDIS won the New technology certification in Korea Institute of Technology and Standards. New technology certification is a system that evaluates the quality, performance and manufacturing process of the first developed technology or product in Korea and gives a New Technology mark (NT) to new technology or product for superior technology and products.
