OLED Materials
Premium OLED materials for displays
In recent years, Organic Light Emitting Diode (OLED) technology has gained an increased role for display applications. As one of the leading manufacturers of OLED materials, EMD offers a complete product portfolio of materials for OLED displays. The portfolio includes small molecules 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, EMD will provide effective application support to optimize the material stack in close cooperation with the customer.
Applications - The world of OLED displays
EMD's OLED materials are used in OLED displays that offer an unparalleled viewing experience with a number of benefits. Among these benefits are extremely wide viewing angles, superb video capabilities, very high intrinsic contrast at any viewing angle, low power consumption for mobile applications, and remarkable lifetime. With its extraordinary properties, OLEDs are a promising display technology for the future. Applications range from simple passive-matrix monochrome and area-color displays to active-matrix full-color displays. Today, the technology is used predominantly in cell phones and MP3 players. Several companies have announced future products utilizing OLEDs in notebook computers, PC monitors and eventually TV screens.
The technology - How do OLEDs work?
OLEDs work by the passage of an electrical current from two conducting electrodes through layers of organic semiconductor materials on a substrate. The semiconductor materials can be based on either small molecules (SM) or polymers (PLED). The substrates are usually indium tin oxide (ITO) coated glass, silicon, or a functionalized 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, which enables fine color tuning of the device
OLED's high precision emissive thin-film structure and excellent optical properties with low power consumption offer considerable advantages to display manufacturers and end users alike. Additionally, as OLEDs are fabricated into extremely thin layer structures, the resultant thickness of the display is essentially that of the substrate. OLED advantages include thinness, decreased weight, and potentially lower manufacturing costs than conventional display technologies.
