Experimental demonstration of micro LED to micro LED visible light communication

ICT Express
LED-to-LED visible light communication (VLC) is a technology that LEDs are used as both transmitters and receivers. In this paper, we studied a micro-LED-to-micro-LED VLC since micro LEDs have faster modulation speed and are used in various applications ...

Micro-LED waveguide for fluorescence applications [PDF]

2019 IEEE Photonics Conference (IPC), 2019
A micro-LED-coupled multimode slab waveguide is reported for fluorescence sensing. The device consists of a 1-dimensional micro-LED array coupled to a sub-mm polymeric slab for evanescent excitation of fluorescent analytes present on the surface.

Alleviating the crosstalk effect via a fine-moulded light-blocking matrix for colour-converted micro-LED display with a 122% NTSC gamut

Light: Advanced Manufacturing, 2022
One of the major challenges when fabricating high gamut colour-converted micro-light-emitting diodes (LEDs) displays is severe crosstalk effect among adjacent pixels because of the wide view-angle feature of micro-LED chips.
