hi don
sorry your right, was just asking a general question really, if i see a resistor going to the positive of the backlight led of the display can i assume its a current limiting resistor and therefore i dont need to protect it

ive got other displays that also have a 68 ohm resistor to the anode, i soppose it must be as it limits the back light to 75ma, and the data sheet says absolute max is 220ma
thanks
