Polarizers
|
|
|
Polarizer is a multi-layered optical film of polarizing function, which transmits the light in certain direction only. The film is indispensable for TFT LCD module, which is widely used in monitors and note PCs.

Phosphors
|
|
|
Phosphors are the material on back glass that emit the visible light that makes up the picture we see. On a cathode-ray tube (CRT) the phosphors are on the front glass and are excited by a beam of light from the cathode-ray. On plasma monitors the phosphors are excited by UV light produced by electromagnetically charged plasma.

OLED(Organic Light Emitting Diode)
|
|
|
A display screen that uses carbon-based film between two charged electrodes is called an OLED. When an electrical current is applied, a bright light is generated. OLEDs are lightweight and durable. They are ideal for screens on portable equipment. Since the OLED emits light, it does not need to be backlit like an LCD (Liquid Crystal Display) screen, resulting in improved power efficiency. OLEDs also offer fuller viewing angles and greater brightness than LCD displays.

Photosensitive Materials for LCD
|
|
|
The color filter photoresists that LG Chem has developed through its proprietary technology, is a high value added product that projects colors in LCD, and used as key material in semiconductor processing, photo lithography, dispersion technology, material engineering, and precision industries. The overcoat photoresists for TFT-LCD, also developed for the first time in Korea, determines LCD screen quality by allowing wider angle view, flattening color filter surface, and protecting the color filters. It leads the domestic market with distinctive technology and quality for next-generation organic EL displays.
