Biphasic micro-LED driver for optogenetics
2016 IEEE Biomedical Circuits and Systems Conference (BioCAS), 2016Optogenetics is a gene-therapy technique which utilizes high radiance light to stimulate the genetically modified nerve cells. An optical delivery method in brain tissue for optogenetics can be performed using incorporated micro-LEDs. Optrode lifespan can be affected by the electrodes degradation caused by the generated charges over the tissue after ...

Development of Micro-LEDs and Applications
2019 IEEE Photonics Conference (IPC), 2019Since our invention in 2000 [1–4], microLED has emerged as a promising technology for a range of applications. MicroLED can provide much higher brightness levels than those of LCD and OLEDs. Therefore, microLED arrays are ideal for self-emissive microdisplays [3–9] and ultrahigh brightness and resolution large flat panel displays [9].

GaN micro-LED arrays with integrated sapphire microlenses
The 16th Annual Meeting of the IEEE Lasers and Electro-Optics Society, 2003. LEOS 2003., 2004GaN microLED devices with integrated microlenses have been demonstrated. The microlenses, with a focal length of 24 /spl mu/m and an r.m.s. roughness of /spl sim/ 1 nm, are fabricated on the polished backside of the sapphire substrate by inductively-coupled plasma (ICP) etching.

Cross talk in full-color micro-LED displays
Optics LettersTo achieve full-color micro-LED displays using color conversion methods, the effects of three-color cross talk and blue-light cross talk on the color conversion layer were investigated. A light simulation was used to analyze the three-color cross talk caused by different pixel banks, comparing pixel banks made from ordinary photoresist and black ...
