Hi,
I just installed this LCD:

to replace the dead one in an Alesis QuadraVerb (this doesn't really matter, it's more of a generic question).
The LCD display itself work fine but to get power to the backlight I ran the 5V source and ground that supplies the LCD part to the LED blacklight and it works too. However I'm wondering if I need to add a resistor to limit the current to the backlight like I normally would with regular 5mm LED. I've read the specs on the backlight but they aren't given as simply as:
# 30mA (max) # Typical Voltage is 2.0, with a maximum voltage of 2.8V
like I'm used to.
Can anyone point me in the correct direction?
Thanks!
