Hi Team,
I have come across many LEDs decorative displays on the street which contains many LEDs arranged in a specific design and some of them also glow in specific patterns.
How to drive such hundreds of LEDs and Is there any IC/module for such applications? I had inspected the back panel of the display but there isn't any complex IC/module. Here is the picture of such display for your reference and also watch the video (
www.youtube.com/watch 35 seconds to better understand the concept.

Normally ICs come in 8 pin/16 pin/28/ pin configurations. However to drive such large number of LEDs we need many ICs. Is there any technique to drive such large number of LEDs with fewer ICs?
Thanks,
Arun
