So far I have only ever seen 6cm x 6cm RGB LED Matrix and nothing smaller. Do they come in smaller sizes?

No I mean an 8x8 RGB Matrix.

Ohhhh, you meant a rgb matrix, like it says in the title I did a poor job of reading  ::)

How small are you hoping to go ?

The design intent of these parts is to go into high-visibility high-power long range displays.  From casino machines to Times Square newstickers to Jumbotrons.  Bigger is better, because people won't be standing within arm's reach of them.  The 60mm size just ended up being something of an industry standard.

Any smaller parts are going to be for "arm's reach" applications, and they will go with a much more efficient scheme to display much higher resolution:  LCD, OLED, etc.

Heh.  Who has a library to turn a typical AM LCD panel into something that looks like an RGB LED array ?
(that would actually be pretty neat, and possibly within the realm of something actually doable on an Arduino, since you could configure the amount of storage actually used to match the app...  Where's that Sparkfun display...)

I think you are more in the realms of RGB OLED displays here. It depends on how many you were planing to stack together. But small displays like 100 by 100 might suit what you are trying to do.

Yeah but OLED's aren't as much fun as an LED array. ;)

Yeah, but you cant 'touch' an LED array to change its output ... well, not more than once  8-)

zooto68

Sure you can. LED's can be used as feedback devices too :)

That is true.

And half the fun is interfacing all those LEDs to make an Image, not just running an LCD screen!

Exactly!! It's more of a challenge. :)

Making your own RGB LED matrix would be a good challenge!
