Premium OLED materials for displays

In recent years, Organic Light Emitting Diode (OLED) technology has gained increasing importance for display applications. As one of the leading manufacturers of OLED materials, Merck offers a complete product portfolio of materials for OLED displays, comprising small molecule as well as polymer materials (evaporable and soluble systems), under the brand name livilux®.

Your advantages - High-purity and high-stability materials

Based on more than 10 years of experience in manufacturing OLED materials, a strong worldwide intellectual property position, and the background of more than 100 years of expertise in high-tech product development, we can supply high-purity and high-stability materials that exactly meet customer requirements.

On request, Merck will provide effective application support to optimize the material stack in close cooperation with the customer.

Applications - The world of OLED displays

Merck's OLED materials are used in OLED displays that offer an unparalleled viewing experience with a number of benefits, among them an extremely wide viewing angle, superb video capabilities, very high intrinsic contrast at any viewing angle, a low power consumption for mobile applications, and a remarkable lifetime.

With its extraordinary properties, OLEDs are a promising display technology of the future. Possible applications range from simple passive-matrix monochrome and area-color to active-matrix full-color displays. Today, the technology is used in MP3 players and high-end cell phones and it is likely to soon be used in notebook computers, PC and even TV screens.

The technology - How do OLEDs work?

Based on either small molecule (SM) or polymer (PLED) materials and technologies, OLEDs work by the passage of an electrical current from two conducting electrodes through layers of organic semiconductor materials on a substrate, usually indium tin oxide (ITO) coated glass, silicon, or a special plastic substrate. Light emission is caused by electrically generated electron-hole pairs forming neutral excited states that relax to a ground state with the emission of light. Importantly, each individual OLED material has its own characteristic emission color.

OLED's high precision emissive thin-film structure and excellent optical properties at low power consumption offer considerable advantages to display manufacturers and end users alike. Additionally, as OLEDs are fabricated into extremely thin layer structures and usually need only a single substrate, they are thin, light and potentially offer lower costs.
