Liquid OLED Opens New Avenues

The latest issue of the Applied Physics states that scientists from the Kyushu University of Fukuoka in Japan have made liquid OLED.

Chihaya Adachi and Denghui Xu, the scientists responsible for the liquid OLED, have opened up new avenues in the OLED market. OLED panels can be more flexible now and can be used in several other electronics applications.

Liquid OLED retains the same qualities of the organic light emitting diodes. It does not require backlight as it gives off light by itself. Ethylhexyl carbazole has been used as the semiconducting layer because it has a high hole mobility.

This makes the liquid OLEDs have a great electrical conductivity. The OLED devices will have decreased degradation and increased reliability. Solid rubrene was used to dope the Ethylhexyl carbazole.

OLED liquid can be used in curved devices without compromising on the image quality. The liquid OLED will fill up all the gaps between the electrodes to give excellent image quality.
