Breakthrough in Miniature Displays
Physicists at Julius-Maximilians-Universität Würzburg (JMU), Germany, have made significant progress towards luminous miniature displays.
A research group led by Professors Jens Pflaum and Bert Hecht has created "the world's smallest pixel to date" with the help of optical antennas.
"With the help of a metallic contact that allows current injection into an organic light-emitting diode while simultaneously amplifying and emitting the generated light, we have created a pixel for orange light on an area measuring just 300 nm x 300 nm. This pixel is just as bright as a conventional OLED pixel with normal dimensions of 5 µm x 5 µm,"
said Bert Hecht, describing the key finding of the study. The results have been published in Science Advances.
The new pixel measures 300 nm x 300 nm and is as bright as a conventional OLED pixel with normal dimensions of 5 µm x 5 µm.
