What is pinout on 6 pin connector on iPhone 6 Plus backlight?


I bought some iPhone 6 Plus 5.5" LCD Display Screen Backlights.

My goal is to use these as sculptures, not to fix old phones. I just need to know the PINOUT - what voltage to apply to which pin to get it to light up. I did a bunch of research and I found that some of these backlights require both 12v and 16v and some have multiple ‘hot’ pins. Seems like all the backlights are a bit different and I can’t find the PINOUT for this model.

I’m also wondering if these backlights need resistors or if there are tiny resistors in there somewhere already?


Or anyone know of a simpler phone backlight? doesn’t have to be this exact model, doesn’t have to be iPhones, any kind of phone backlight could be fine. Ideally, it would be 5v but I bought step-up buck converters so higher voltage is fine also. Simpler wiring situation (2 or 3 pin?) would be helpful. iPad backlights would be an interesting option also but do they also have mutiple voltages?


Hey everyone, thanks for helping me get the answer to a simple but obscure technical question. I have reached the limit of my electrical hacking. I really appreciate it!

ahh, now that i look closer i see there are 6 pins! here is a photo just FYI

ari this should be for the 6 S backlight and similar to the ones you are looking at. Count the pins with the light facing up and the connector down from left to right:

pins 1 & 2 = ground

pin 3 = +18V

pin 4 = +12v (a 300ohm resistor will illuminate both sections equally)

pins 5 & 6 = ground

so you are saying i need to add a resistor to pin 4 in order for the whole thing to be evenly illuminated? what if i simplified and just ran the whole thing on 12v - maybe it would be a little dimmer but still work?

so for pin 4 - which ground shoudl i use for that one?

i am making note: there are 12 LED's that make up the backlight. Each LED is a 3V LED. Two separate grounds for the two 18V circuits makes it 3 V in the 12/2 LED circuits.

1 ground for each circuit. so you need separate grounds for the 18V and the 12V circuit. It will all depend on what kind of power supply you are using. You can run two ground wires from the same ground connector on your power supply. Yes it should still work without the resistor but you may have brightness variation between the two circuits. I think at this time you could give it a try and see what it looks like. If I get those films before you do let's compare notes. :-)
