At this years Society for Information Display (SID) 2008 Trade Show, Kodak demonstrated the World's First 100% NTSC White OLED Display Showcasing Kodak Deep Blue. The 8-inch panel demonstrated
Kodak first discovered organic materials that glowed in response to electrical currents in the late 1970s. Since then, Kodak has set industry benchmarks with patented discoveries and OLED technology.
Kodak's materials discovery research addresses molecular design and synthesis of organic materials for their chemical and physical properties. Computational analysis is used to model and predict the molecules' behavior. Physical chemistry expertise helps to understand how chemicals interact and how changes in their properties affect their behavior. Finally, materials analysis determines what is happening when molecules interact.
In the late 1970s, Eastman Kodak Company scientist Dr. Ching Tang discovered that sending an electrical current through a carbon compound caused these materials to glow. Dr. Tang and Steven Van Slyke continued research in this vein. In 1987, they reported OLED materials that became the foundation for OLED displays produced today.
The first color “discovered” in this early OLED research was green. Kodak has since improved the purity and brightness of color. As early as 1989, the Kodak research team demonstrated color improvements using fluorescent dyes, or dopants, to boost the efficiency and control of color output.
Third-generation OLED materials from Kodak are vibrant. Full-color displays far exceed LCDs’ color gamut – by as much as 20 percent – and surpass performance in lightness and luminance.
Until now, display technology has presented only a fraction of what can be captured digitally. Gauging OLED color performance in terms of hue, chroma and lightness reveals the materials’ advantages in showing bright, vibrant images with strong color fidelity.
