OLED Displays Are Now 2x More Efficient
Researchers from the University of Toronto have developed a special technique that produces OLED devices that will encourage consumers to adopt OLED technology embedded within flat-panel displays and through various lighting technologies.
The process requires the production of a one-atom thick sheet of chlorine onto the surface of indium tin oxide material. The layer of chlorine is applied to the surface with an ultra violet assisted process that negates the need for chlorine gas. The indium tin oxide is used as the electrode material that is currently found in flat panel displays. The outcome of this engineering process would be a more efficient and less costly OLED device.
When testing the chlorine OLED against a traditional OLED, the researchers found the efficiency to be double at a very high brightness within the display. Although traditional OLED displays are much more efficient than liquid crystal displays, the efficiency is cut drastically as the brightness goes up. With the Cl-OLED, the Toronto researchers were able to prevent the drastic drop and achieve a “record efficiency of 50 percent at 10,000 cd/m2.”
