Abstract
There is provided an organic light emitting diode (OLED) comprising an organic electroluminescent layer formed between a first electrode and a second electrode, characterised in that organic electroluminescent layer comprises a nano-structured grating pattern provided therein, wherein the grating is configured to modify the refractive index of the electroluminescent layer.
Claims19
An organic light emitting diode (OLED) comprising:
- an organic electroluminescent layer formed between a first electrode and a second electrode, characterised in that the organic electroluminescent layer comprises a photo-crosslinkable liquid having dichroic molecules therein, a nano-structured grating pattern provided therein, wherein the refractive index of the grating is tuneable to effect a variation in the peak wavelength of the OLED. layer.
(canceled)
A method of fabricating a nano-structured grating pattern in a photo-sensitive organic electroluminescent layer of an OLED, the method comprising the steps of:
- illuminating the organic electroluminescent layer with first and second light beams having an angle θ therebetween, wherein the first and second light beams are configured to create an interference fringe in the organic electroluminescent layer.
(canceled)
An OLED as claimed in any preceding claim, wherein the period of the grating is approximately 300 nm.
