OLED - AMOLED and PhOLED

​

Organic light-emitting diodes (OLED) are extensively used in devices such as television and mobile phone screens. OLED's are generally made of thin layers of organic molecules between two electrodes. The devices emit light when an electric current flows through them.

Until a few years ago, the biggest technical problem for OLED's was the limited lifetime of the organic materials, typically half that of LCD, LED, or PDP, as heat and oxidation generated during operation contribute to the instability of the chemicals. This problem was solved by deuterating some of the organic molecules incorporated into OLED's, which increases the lifetime of the device by a factor or 5 to 20 without significantly affecting the other properties of the device.

Another application of deuteration in this field is the neutron reflectometry along with deuteration of specific molecule layers that has become the key method for the study of morphology, diffusion and interfacial behaviour in organic thin-film semiconducting devices.
