Color Filter TOPTICAL™

Overview

Liquid Crystal Display Color Filter TOPTICAL™ is a color filter essential to color liquid crystal displays.

Features

  1. The color filter can be formed on the top of a thin glass plate.
  2. Super high-definition processing as well as high OD can be achieved through the non-photosensitive polyimide method.
  3. Supports both active matrix and passive matrix methods.
  4. Power saving color filters for "reflective LCDs," "semi-transmissive LCDs," and "high transmissive-type LCDs."

Applications/Usage

It is a high-definition color filter made with a polyimide-based pigment dispersion method, with excellent color characteristics, heat resistance, and durability. It is used in a wide range of applications, such as cell phones, game devices, car navigation systems, and monitors, etc.
