Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic ...

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 ...

The evolution of LED technology has led to the development of several types, primarily inorganic LEDs, OLEDs, and QLEDs. Inorganic LEDs are known for their durability and energy efficiency, making ...

Scientists in Korea have built a light-emitting diode (LED) facade that can be used in combination with building-integrated PV, with minimal power loss caused by shading. The grid-type LED display can ...

Burn-in is often overblown, but understanding the phenomenon is still important.

Colloidal quantum dots (QDs) exhibit exceptional properties of narrow-band emission, tunable luminescent wavelength, high luminous efficiency, and remarkable material stability across the visible and ...

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

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 ...
