16×24 RGB LED Matrix

The most significant part used in this project is Texas Instruments’ TLC5940 LED PWM driver. It uses a clocked serial data input, and provides 12 bits of PWM resolution on each of 16 outputs.

Normally, the TLC5940 would require one output for each LED element. Since there are three elements per RGB LED, this would add up very quickly; the planned array would require 3 * 24 or 72 TLC5940 chips.
