OLED Display and Pixel Structure Display Pixel Cover glass Cathode Cathode (Ba,Ca/Al 2000 ). Emissive polymer layer Emissive polymer layer ~ 800 . Conducting Conducting polymer layer polymer layer ~ 1200 . Epoxy Anode (ITO 1500 ). Anode Single pixel structure Glass substrate Human hair is 200X the thickness of the OLED layers Homer Antoniadis | OLED Product Development|.
Samsung-NEC Mobile Display (SNMD) (2002)! RiTdisplay (2003)! Sanyo-Kodak (2003)! R, G, B colors available! limited lifetimes for blue! Shadow masking allows easy patterning for area color ! presents challenges with scalability and high volume manufacturing! Shadow masking challenging for full color! high throughput and scalability is a challenge
