I am not sure where to put this question, but here i think are a lot of smart people with a lot of knowledge and understanding of hardware and software.
I am building my own custom ardunio laptop. I am using a LCD controller kit that i have hooked up to a display.
Everything is working, but the battery for the screen is using to much energy. Also the brightness of the screen is too much. Using hardware and software switching makes the screen appear less bright but this is not really effecting the back-light. It just makes it look like so.
Using my brain i figured out what cables are used for only the back-light of the LCD. Which raised extreme interest in lowering the brightness somehow.
I want to put an resistor in between the cables in a way that the brightness will be lowered.
However i have no clue what cables, and what the cables mean. And i hope someone here can tell me this, or redirect me to some other forum where i can be helped.

I took a photo of the cables that are used for the back-light, could not upload it here so :
Thanks for help !
