Connect 3 different LCD units to one Arduino Uno & display different things?

Hi, I have an Arduino Uno and 3 rgb_lcd Grove units. I'm trying to connect all of these LCDs to my Arduino to have them all display different things. How can I do this?

I tried to instantiate them separately i.e. rgb_lcd lcd1; rgb_lcd lcd2; rgb_lcd lcd3;, but this didn't work. Any suggestions?

Any suggestions?

Post your code.
Post a data sheet for the displays.
Read the how to use this forum sticky to see how to post code and some advice on how to get the most from the forum.

"but this didn't work" is not helpful. Please explain what happened versus your expectations of what would happen.

Something that shows the wiring (wiring diagram, schematic, or ?) might also help.
