LG Display to invest $2.6 billion in OLED

LG Display has announed it will invest $2.6 billion in an organic light-emitting diode (OLED) panels production line in South Korea.

The display screen maker said in a statement it would continue to expand its lead in the OLED TV market.

LG Display is shifting its mainstay liquid crystal display (LCD) business toward next-generation OLED panels, as the LCD panel industry is crowded with Chinese rivals.

What is OLED?

An organic light-emitting diode (OLED), also known as an organic EL (organic electroluminescent) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.

This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent.

OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles and PDAs.

A major area of research is the development of white OLED devices for use in solid-state lighting applications.

An OLED display works without a backlight because it emits visible light. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD).
