چکیده
Abstract A flexible full-color micro-LED display with high mechanical robustness was fabricated by printing quantum dots (QDs) on a blue array using standard photolithography. The red and green colors yielded from QDs exhibit better color gamut than conventional filters. light conversion efficiency enhanced adding TiO 2 nanoparticles to the QD-photoresist composite. This successfully mounted various unusual substrates such as curved glass, fabrics, human skin, enabling diverse optoelectronic applications. In addition, wireless multi-channel visible communication (VLC) based wavelength-division-multiplexing orthogonal-frequency-division-multiplexing (WDM-OFDM) technique demonstrated QD-based panel. data transmission rate of 1.9 Gbps obtained owing electrical–optical modulation bandwidth

Understanding the Communication through Visible Light and its Application
Wireless optical technology like visible light communication is a new approach in terms of security, speed, usability, bandwidth and flexibility for data communication. More and more people with their devices access wireless internet today, due to which clogged airwaves are going to make transmission slow and is full of interference. The solution to this problem of slow speed is that data is to...
متن کاملActive tracking system for visible light communication using a GaN-based micro-LED and NRZ-OOK.
Visible light communication (VLC) holds the promise of a high-speed wireless network for indoor applications and competes with 5G radio frequency (RF) system. Although the breakthrough of gallium nitride (GaN) based micro-light-emitting-diodes (micro-LEDs) increases the -3dB modulation bandwidth exceptionally from tens of MHz to hundreds of MHz, the light collected onto a fast photo receiver dr...

متن کاملImplementation of Downlink Visible Light Communication using LED and Photodiode
In this paper we present the initial design, implementation and result of a small-scale prototype of Visible Light Communication using simple LED and a photodiode. Data is transmitted through visible light by sending data in a binary format as on and off that varies in frequency faster than the human eye can follow. The data to be transmitted is encoded and sent. The data is decoded back at the...
متن کاملLED Modulation Characteristics in a Visible-Light Communication System
This paper conducts a research on modulation characteristics of blue light-emitting diodes (LEDs) used in a visible-light communication (VLC) system. Through analysis of the modulation characteristics of LEDs with different emitting sizes, we find that there is a similar linear relationship between LED’s 3dB bandwidth and the operation current density. This experiment also shows that high serie...
