This finding can help to produce low-cost OLED displays in the coming years, instead of technicians using costly microfabrication facilities to construct small-scale structures such as computer chips, smartphone displays, etc. The detailed study is published in Science Advances . OLED Technology- Overview OLED stands for Organic Light-Emitting Diode- a technology that uses LEDs to produce light by organic molecules. This technology helps to create the world’s best display panels. Organic displays are prepared by placing thin films of organic semiconductors such as silicon or gallium arsenide between two conductors. These films emit a bright light when an electric current is applied. Each pixel emits its own light and is controlled indivi
