Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative ...

Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

This increased optical power output enables higher measurement precision and accelerated processing of biological samples, ...

Light-emitting diodes with an emission wavelength longer than 365 nm typically have GaN or InGaN quantum wells (QWs) in the active region, and those with shorter wavelengths in general have AlGaN QWs.

Experts say a "concerning" number of fireflies are threatened with extinction. Above, fireflies light up the sky in upstate New York. Raphaël De Cock was 9 years old the day he caught his first ...

If you want to bring a wealth of smart features to your existing light fixtures, smart light switches are a wise investment. These replace the traditional switches on your wall, allowing you to ...

OLED, or Organic Light-Emitting Diode, refers to a self-emissive panel technology in which each pixel can be individually lit. QLED, or Quantum Dot Light-Emitting Diode, is an umbrella phrase used in ...

Abstract: The brightness of low-temperature polycrystalline silicon and metal-oxide (LTPO) active-matrix organic light-emitting diode (AMOLED) display under low-refresh-rate driving condition tends to ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Large-area (1075 × 750 μm 2) blue-emitting InGaN/GaN light-emitting diodes (LEDs) fabricated on a 3 μm pitch CES exhibit ∼39% enhancement in the optical power compared to state-of-the-art, ...

The requirements for microdisplays are reviewed, and the case is made that organic light-emitting diodes (OLEDs) are the best candidate transducer technology for meeting these requirements. A 1280 × ...
