Pin 50 Purpose at Screen Connection?

So i upgraded my RAM last week and after i was done, i noticed a pinout wich makes no sense for me. Laptop is a Razer Blade 15 Advanced 2021. Modell: ‎RZ09-0367BGC3-R3G1 Always a little curious when i catch details like this and then i can´t sleep -.- From pin 50 goes a line to a very small smd piece and than to two empty solder spots, the lower one connects to the top dot of solder. What does this pinout do actually if it has a function? (Marked in red) Is it Ground? VCC? NC? Background light vcc or gnd? Does it serve any purpose? I don´t see that on newer generations. Thanks!
