Driving Development of OLED Display Materials

Since 2006, flat-panel display makers have turned to DuPont for the best in quality display materials. In the growing organic light-emitting diode (OLED) market, DuPont has established a leadership role in developing red, green and blue emissive materials that are driving higher OLED performance.

In addition to smartphones, tablet, TVs and the hot wearable-technology market, device makers are adapting OLED displays for lighting and automotive applications, to name a few. In turn, as demand for OLED display panels increases, more panel suppliers are focusing on OLED displays.

For this market movement to continue, developers need a trusted display materials partner that continues to lead the charge in advancing OLEDs’ performance. DuPont is that partner. As a technology leader in active-matrix OLED (AMOLED) emissive materials, we can help you achieve your product and market-readiness goals.

DuPont’s role in OLED evolution

For the last decade, DuPont has taken a leading role in developing new, leading-edge materials to meet evolving industry demands for improved capabilities in product displays. To this end, our OLED R&D engineers developed red phosphorescent OLED host materials. The first-ever OLED device based on our phosphorescent red host was launched, marking the first mass production of such technology. Today, DuPont provides market-leading AMOLED materials with high efficiency, lower driving voltage, high refractive index and longer lifetime for next-generation OLED displays.

Product offerings

  • Emission Layer Material

  • OLED displays are made by placing an organic emissive layer (EML), which is a thin film of organic compound, between two conductive layers. Light is produced by passing electricity through the layer stacks, omitting the backlighting that liquid-crystal displays (LCDs) need in order to produce light. OLEDs’ advantages include:

    • Improved picture quality
    • Wide viewing angle
    • Lower power consumption
    • Thinness and flexibility
