• Photoresists for Displays

  Photoresists being used for manufacturing various display panels such as LCD, OLED, and Micro-LED. The CFPR(Color Filter Photoresists, Color resist, Overcoat, Column Spacer PR, Black Matrix PR)s are widely used to make normal color filter front substrate. Recently Multi-functional Photoresists like PAC, BCS(Black Column Spacer) and Black Bank(Black PDL) are getting more developed and applied for new display panels.

  

• Encapsulation
  Ink

  It is an encapsulating photosensitive material for protecting flexible OLED from moisture and oxygen. The materials can be classified as UV-curable Acryl-based Ink and Epoxy-based Ink, and both materials can be properly coated through inkjet printing process. We can control the refractive index and transmission property of the resulting thin film encapsulation membrane by adjusting monomers and photoinitiators as well as excellent jetting property by adjusting its viscosity and surface tension.

  

• QD PR for
  QLED and µ-LED

  This PRs are applicable to a next-generation display using photoluminescence of Quantum Dot, whose FWHM of the emission light is narrow and wavelength changes according to the particle size of QD. QD is a kind of color conversion material (CCM) that produce G/R color by absorbing blue light of OLED or micro-LED and converting to Green and Red color with longer wavelengths.

  

• Photodefinable
  Dielectric PR for
  Semiconductor

  It is an insulating material required to produce artificial intelligent 3D IC in order to cope with the market change due to the explosive growth of the semiconductor market by the Fourth Industrial Revolution. It is a photo-definable photosensitive material with low thermal expansion coefficient (CTE), excellent heat resistance, chemical resistance, and mechanical properties.
