Japanese scientists have invented liquid OLED technology to create flexible displays

By the Japanese island of Kyushu University of Fukuoka (Kyushu University) (Center for FutureChemistry future Chemistry Center) an academic Denghui Xu and ChihayaAdachi jointly published introduces a liquid OLED display (liquid-OLEDdisplay) technology, which combines the OLED wide color gamut and reinforcement can bend.

This paper introduces a kind of EHCz (9-2-ethylhexylcarbazole) liquid host molecule doped 5,6,11,12-tetraphenylnapthacene (also known as rubrene) - guest luminous body OLED.

So far, the OLED display is solid, and has the advantages of beyond the liquid crystal display (LCD), no backlight; and due to the self luminous characteristics of OLED, in addition to electricity, can also be done very thin. However, most of the current display manufacturers to support a wide range of sizes, lower cost of LCD production, OLED is the main application of small size.

Now the OLED is mainly used for organic thin film of solid and liquid crystal part, no organic semiconductor manufacturers are trying to produce pure liquid; only a small part of the polymer solution (polymersolutions) and liquid electroluminescence (solution-phaseELectroluminescent) exposure component technology. The author expresses.

In addition to contribute to the manufacture of flexible self light emitting display, liquid semiconductor components can also enhance the reliability and life of FET, solar cells and other organic semiconductor systems. The authors of the report also proposed a "cyclic OLED", the internal liquid organic semiconductor material of this component will be recycled or re filled to the active light-emitting layer (activeemitting layer).
