Abstract
Light-Emitting Diodes The GaN-based blue-light-emitting diodes (LED) chips with 4 × 4 arrayed pixels are fabricated and packaged by chip-on-board (COB) technique and welded on printed circuit board (PCB) as white-LED modules. The size of the mesa and the electrodes are carefully selected to get a compromise between the luminous flux and the modulation bandwidth for the dual function of illumination and communication. More details can be found in article number 1800484 by Huamao Huang, Hong Wang and co-workers.
