Researchers at a Japanese University have developed a groundbreaking OLED technology that is claimed will significantly ease the creation of curved displays and drastically improve their lifespan.
Usually, OLED displays use solid-state organic films that give off light when an electric current is applied. One significant benefit of OLED displays compared to traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight. For this reason, OLEDs can be made very thin and flexible, as well as use less power, enabling them to run longer on a single battery charge.
The new liquid-OLED could achieve these same benefits, but by using a liquid organic semiconductor instead of the solid-state films. Other than a few previous studies that have investigated using polymer solutions as the semiconducting layer, this is the first time that researchers have attempted to fabricate a practical liquid semiconductor for OLEDs.
Another advantage, according to the Japanese scientists, is that by utilising a recirculating system the fluid OLED layer could be refreshed, thereby extending the lifespan of the display.
The scientists will, however, have to overcome a problem with the light output of the liquid-OLEDs. Apparently, although the light output is visible to the naked eye, it does not currently match that of traditional OLED display products.
