High bandwidth GaN-based white light-emitting diode (LED) was fabricated using GHz bandwidth blue LED chip combined with CdSe/ZnS semiconductor quantum dots (QDs). The maximum optical power of the ...

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 ...

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 ...

The Glyph Matrix is a smaller LED display on the upper-right corner of the rear of the Nothing Phone (3) that uses dot-matrix ...

Two-dimensional (2D) release layers are commonly used to realize flexible nitride films. Here, high-quality, large-area, and transferable nitride films can be precisely controlled grown on ...

Dalian University of Technology researchers advance flexible circuits using 3D printing - producing freestanding 3D ...

Today’s LED lights offer warm colors, smart connections -- and higher prices than old incandescents. That's what makes it so disappointing when they suddenly fail after a year or two of use even ...

Moreover, electroluminescence (EL) from our ZnO/Si nanotips array light-emitting diode (LED) has been demonstrated. Our results could open up new possibilities to integrate silicon-based ...
