The evolution of next-generation cellular networks is aimed at creating faster, more reliable solutions. Both the next-generation 6G network and the metaverse require high transmission speeds. Visible light communication (VLC) is deemed an important ancillary technology to wireless communication. It has shown potential for a wide range of applications in next-generation communication. Micro light-emitting diodes (μLEDs) are ideal light sources for high-speed VLC, owing to their high modulation bandwidths. In this review, an overview of μLEDs for VLC is presented. Methods to improve the modulation bandwidth are discussed in terms of epitaxy optimization, crystal orientation, and active region structure. Moreover, electroluminescent white LEDs, photoluminescent white LEDs based on phosphor or quantum-dot color conversion, and μLED-based detectors for VLC are introduced. Finally, the latest high-speed VLC applications and the application prospects of VLC in 6G are introduced, including underwater VLC and artificial intelligence-based VLC systems.

With the continuous update of industry technology, LED LCD displays are developing rapidly in the direction of high-brightness and full-color development. All-round color LED LCD displays are better and better showing their broad industry applications. The article is based on a non-volatile ferroelectric read-write memory chip designed for outdoor sports competitions full-color LED display. First, the detailed design introduces the actual design and application of the non-volatile power data management memory in the design of the power management data network management control software chip system and the principle of the control software, and analyzes in detail how to realize the specific design functions according to the specific design specifications of the software system. , And then a new power management control system management software system that can scroll the full-color node LED horizontally on the display screen, adopts the power network management ARM Cortex-M3 core and uses the power supply microprocessor and network STM32 as the power supply The management control software system center, with the power network management FPGA as the central system, completes the high-speed horizontal scrolling of the entire scrolling display screen and the scrolling refresh of the display screen, and completes the system control software principle and design layout of the power management layer and the network PCB power supply Control and manage the software processing design of the layout, the hardware processing design of the circuit board and the software installation and debugging. The LED display screen can meet the functional requirements of outdoor sports games, and the display rate of the image of the LED full-color display screen has reached 91.82% on average, which has good stability.
