The LED drivers supply up to 55mA per channel, and there are 16 channels. each channel is a series of LED's. The max voltage the driver can handle is 36V, so now knowing I can string different colors in series (i had read that you can, and then i read you cant so i was just making sure) I can have approx 12-15 LED's per channel (depending on color ratio). So 1 driver chip can drive 190-240 LED's. 5 driver chips will be more than enough for 1 panel.
