LED Displays: Multiplexed Matrix

This lecture covers LED displays and signs, focusing on multiplexed matrix displays. Topics include the use of temporal multiplexing, programming techniques, consequences on brightness, and circuit architectures. The instructor explains the impact of increasing the number of LEDs, the organization of anodes and cathodes, and the use of demultiplexers. Different multiplexing strategies are compared, highlighting trade-offs between luminosity and circuit complexity. The lecture also delves into programming aspects, detailing display cycles and control procedures. A modified control program is presented, demonstrating how to animate LED matrices effectively.
