OLED technology is based on the phenomenon that certain organic materials – carbon-based compounds – emit ... a conductive layer, an anode, and a cathode. When a voltage is applied across the OLED ...

We discovered that adding a base molecule *2 to the electron-supply layer on the cathode inside an OLED allows us to supply electrons to the organic layer containing the light-emitting material ...

OLED materials include substrates, encapsulation, cathode, anode, hole injection material (HIL), electron transport material (ETL), emissive material (EML). WILMINGTON, DE, UNITED STATES ...

To realize the all-printed organic stack structure for OLED devices, and prevent the evaporation of ETL that covers the contact metal of auxiliary cathode, high-performance soluble ETL materials ...

For the cathode, [Ian] is using a gallium-indium-tin eutectic, an alloy with a very low melting point that allowed him to deposit a small puddle in his OLED stack. With the anode and cathode taken ...

Eighteen years after the development of the first polymer-based LED display, the technology has finally matured and polymer OLED televisions are just around the corner. So much has changed since ...
