With advances in LED technology there is a growing demand for measurement systems to evaluate LED characteristics.

Diphenilamino-substituted carbazoles were used as guest compounds for the preparation of highly efficient blue organic light-emitting diodes based on the phenomenon of delayed fluorescence. It was ...

This letter proposes an analytical model on the energy efficiency for visible light communications (VLC) based on light-emitting diode (LED). We certify the variation pattern of energy efficiency of ...

In modern devices, such as phone screens or advanced sensors, light is often generated by pairs of organic molecules, where one molecule, known as the donor, transmits electrons, and the other, ...

Gastrointestinal cancers remain among the most common forms of cancer. While endoscopy has become a cornerstone of cancer ...

Stability is becoming a main issue for perovskite light-emitting diodes (PeLEDs), as their external quantum efficiency (EQE) has been boosted to above 20%. An all-inorganic perovskite, cesium lead ...

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...
