Substrate & Material COF Chip On Film Applicable products
  • Smartphone
  • Notebook
  • Display
  • OLED/LCD TV
  • Wearable

COF is a key component for displays that transmits electric signals that drive each pixel on the panel. A display driver IC is mounted on the substrate to interconnect a display and a PCB.

Value proposition / Competitiveness

  • 01 Fine Pitch Patterning Reducing the inner lead pitch of a driver IC (reduced chip size) and implementing multiple channels
  • 02 High flexibility and compact size Realizing a larger degree of freedom for connecting module components, and reducing the size of assembly areas
  • 03 High-resolution optical inspection Automatic precision inspection of micro-circuits
