The III-nitride light-emitting diodes (III-N LEDs) coated with phosphors are currently the most efficient white light sources for general lighting 1,2,3,4. The most efficient violet III-N LEDs reach ...

Organic light-emitting diodes (OLEDs) are now widely used. For use in displays, blue OLEDs are additionally required to supplement the primary colors red and green. Especially in blue OLEDs, ...

Organic light-emitting diodes are used in smart phones, tablets, and large TV screens. As they do not need any additional background illumination, they are energy-efficient. The can be produced at low ...

The first directly emissive colour displays were developed in the 1960s and relied on red gallium arsenide (GaAs) and green gallium phosphide (GaP) light-emitting diodes (LEDs) 1. Subsequently, yellow ...

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 ...

Driven by superior features and falling costs, the market for light-emitting diode luminaires, or optimized permanent light fixtures, will grow more than 12-fold over the next decade -- from $2 ...

Ten boron atoms in one molecule squeeze its light into an ultra-narrow band, boosting OLED color purity for sharper, truer ...

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, as demonstrated by researchers from Tokyo ...

When deciding what kind of TV to get, narrowing down your options can feel difficult. One of the biggest factors is whether ...

When an AMOLED screen is mentioned in a spec sheet, chances are you're talking about a smartphone. There are a few good ...

LG Display’s organic light-emitting diode (OLED) has received global certification for most accurately reproducing the colors ...
