A solar cell moonlights as an LED, both absorbing and emitting light more efficiently
Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor ...
A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...
Several gloved hands hold the corners of and twist a thin screen that is glowing green. Organic light-emitting diode (OLED) displays can now be designed into flexible, stretchable screens like the ...
