Organic light emitting diodes.

2004
A method of fabricating an OLED element or display having two or more OLED layers is described entailing providing a blocking layer by printing with an ink in a desired pattern between two of the OLED layers, whereby, in use, conduction across the OLED element or display is reduced in the area of the pattern, wherein the ink is colored to increase ...

A Thermally Stable Organic Light-Emitting Diode

1995
The design of organic electroluminescence (EL) devices meets several barriers, thermal stability and injection ability of charge carriers from the electrodes being important examples. In spite of considerable efforts to surmount them,1 they still create serious problems and require more experimental data and profounded knowledge on the device operation.

Light manipulation for organic light-emitting diodes

SPIE Proceedings, 2014
To realize high-efficiency organic light-emitting diodes (OLEDs), it is essential to boost out-coupling efficiency. Here we review our latest reports upon light manipulation for OLEDs by integrating a dual-side bio-inspired deterministic quasi-periodic moth’s eye nanostructure with broadband anti-reflective and quasi-omnidirectional properties.

Light Emitting Efficiencies in Organic Light Emitting Diodes (OLEDs)

2001
The interface between the organic layer and metallic anode of an OLED is crucial to the stability and the performance of the device. The α-septithiophene (α-7T) has been used as the buffer layer at the interface between the ITO electrode and the hole transport layer (HTL).
