How does the backlight work on these LCDs? Is it a pair of coloured leds? I've got a backlight from a broken LCD (the backlight still works) but it looks different to the nuelectronics shield backlight, the busted one has a single anode/cathode pair of pins that are on a white bit of plastic that is the base, the nuelectronics has 2 pairs of A/K and look like they go into to little square lumps of plastic (like leds :D) .
The busted one looks like an EL panel style light box, although I thought they need specific power supplies for driving them, I just connected the AK to a pair of 5v with a resistor. I don't want to destroy it as it can be used elsewhere but i would like to know about swapping out either the whole nuelectronics backlight or if it simply means replacing some leds that would be cool as I'd prefer a red backlight or maybe even break out my own RGB kind of thing for it (red for protecting night vision as bright green/blue light is a pita for astronomy).
