Organic light emitting diode(OLED) is a thin film multilayer device composed of carbon molecules or polymers including metal foil, film or plate (rigid or elastic ...

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 ...

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 ...

The development of organic light-emitting diode (OLED) visual display technologies harnesses the properties of two key techniques: photoluminescence and electroluminescence. Confocal microscopy can be ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...

Wearable electronics have evolved from basic fitness trackers to sophisticated health-monitoring systems, demanding light-emitting devices that balance visual quality, power efficiency, and mechanical ...

A new type of OLED (organic light emitting diode) could replace bulky night vision goggles with lightweight glasses, making them cheaper and more practical for prolonged use, according to researchers.

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

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 ...
