Outdoor Full-color LED Display for Sports Games Based on Non-volatile Ferroelectric Read-write Memory Chip

Abstract

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.
