An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

This video explains how LEDs (Light Emitting Diodes) function and why they are widely used in modern electronics. LEDs produce light by emitting energy when electrons recombine with holes in a ...

While OLEDs offer an excellent viewing experience, the faint burn-in you may notice on your screen is a notable drawback. Here's how to prevent it.
