I recently picked up a Lumex 4 line LCD with a backlight. The LCD works fine, but I can't figure out how to power the backlight. The datasheet for the LCD is pretty lame and didn't mention anything about the backlight. Powering it directly from the 5V is not what I want to do since I am pretty sure it is an LED backlight, but if I put a resistor in series it doesn't light very much. Does anyone know the proper way to light the backlight? What voltage or resistor value I should be using? My LCD is LCM-S01604DSF if that helps.
Thanks
