Japan develops next-generation OLED components to exceed LED efficiency

The Nikkei News reported on the 28th that the Yamato University OLED Research Center has successfully developed a next-generation OLED device that can be driven with a voltage lower than the theoretical limit (2.38V). According to reports, the OLED components developed by Yamagata University can be driven with a voltage of 1.97V. Under such voltages, the brightness is not high, but if the voltage is increased to 2.49V, the brightness can be increased to comparable to that of large LCD TVs. 1,000cd/m2, further increased to 3.0V (equivalent to two No. 3 dry batteries), the brightness can be increased to 5,000 cd/m2 of comparable fluorescent lamps, and its efficiency will exceed that of LEDs.

According to the report, the power consumption of products using the above-mentioned newly developed OLED components can be reduced by about 30%, so in the case of higher efficiency than LEDs, the possibility of rapid popularization of OLEDs will be greatly improved. The report also pointed out that the products developed by Yamagata University are green OLEDs, but the application of newly developed technology can also achieve the same effect on white OLEDs, and Yamagata University plans to halve the power consumption after three years.
