64x64 Full Color (R/G/B) LED Matrix with High Multiplexing Reference Design

TIDA-00161

Design files

Overview

This reference design is a complete 64 pixel x 64 pixel Red/Green/Blue LED panel with TLC5958 driver IC.
Due to its higher integration and high time multiplexing support, this design drives total 12,288 individual LED lamps (= 64 x 64 x 3color) by only 8pcs of TLC5958 IC.  Still this LED panel maintains very high video output quality.

Features
  • Complete large full color LED panel solution with 1/32 time multiplexing
  • Small number of components on the panel, less than 1/3 of traditional solutions.
  • Only 4 layers of PCB support 12,228 LED lamp connection where it is difficult to achieve the same connection with 8 layer PCB with traditional solutions.
  • The TLC5958 provides multiple of image enhancement features offering better video compared with traditional solutions.

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
