Business information

Leading display revolution through technological innovation.

Organic Light Emitting Diode (OLED) is a display device consisting of organic emitting compounds.

Thin, light, flexible, and transparent display suitable for car display and AR/VR.

Used for illumination as well since it emits light similar to natural light.

Doosan Solus has independently developed OLED materials, new functional materials, and QD materials through continuous R&D for over 10 years, leading the global display materials market. It also plans to expand its business lines steadily by developing products for materials for electronic devices related to the 4th-generation industries, including semiconductor chips and battery.

Structure of OLED

OLED (Organic Light Emitting Diodes)

The OLED display has the advantages of high luminance and efficiency as well as wide viewing angle that provides excellent color expression.

In addition, it has high operation speed and it can be driven at low voltage. A thin, multi-type display can be created as it emits light without the need for backlight.
