i have some blue backlit lcd's but i dont know if the resistors on the back goto the led backlight or not as i cant trace them, but my main problem is i have a vague memory of once reading that lcd leds had very very small I requirements! i should have written it down because i cant now find the info, so my question is as a rule of thumb do they come with resistors already on?and if not or maybe anyway does anyone have a clue roughly what a normal hitachi type 2 line lcd need current wise for the back light, i was tempted to just try around 10ma but my memory is nagging me and i have a feeling thats actually too high but i dont know!
anyway thank you
