OLED materials make up full-color displays that surpass even LCDs in brilliance and color. And Kodak has continually improved color purity and brightness since its scientists first discovered OLED materials. Today, Kodak’s exclusive color systems, dopants, and other materials are crucial ingredients in industry-leading devices for many applications.

Rich color saturation
Excellent luminous efficiency
Long lifetime
Excellent drive voltage (power) efficiency
Certified, device-tested “EL” grade
Noteworthy color gamut in full-color OLED systems
Third-generation OLED materials.

The development of new materials, particularly for achieving emission in the blue region of the spectrum, for organic light-emitting devices is the focus of intense investigation throughout the world. Scientists have developed a new class of materials that demonstrate exceptional promise for use as electron transport materials within an OLED device. The successful development of practical blue OLED devices would significantly impact advancement of OLED technology in both display devices and energy-efficient solid-state lighting.

These materials address the critical issue of achieving high quantum efficiency (photons generated per electron injected into an OLED device) at low voltages. Devices built at PNNL using the new materials have produced external quantum efficiencies at a brightness of 800 cd/m2 as high as 11% at only 6.3 V without using conductivity doping. One class of new OLED materials developed at PNNL are based on organic phosphine oxide compounds while another is based on organic phosphine sulfides.
