I changed the screen, but the brightness can't be adjusted

Hi! Thanks for reading first.
My laptop is a HP Notebook 15-dy1023dx
The screen is as below, and the part number is L63569-001.
15.6" diagonal HD SVA BrightView micro-edge WLED-backlit touch screen (1366 x 768)

But this screen is broken
I bought the N173HCE-E31 that supports touch on 40 pins.
It corresponds to part number L69126-001.
However, the screen appears fine, but the touch does not work and the screen brightness cannot be adjusted.

1. If I change the cable, will it work normally? So, which cable should I buy? L63613-001 or L63614-001 ?

2. If the cable doesn't support any, I'm thinking of changing the screen. With 30pin non-touch fhd. If you need to buy a 30-pin cable, L63615-001 and L63616-001
Which of these supports 30-pin fhd?

3. Googling
DD00P5LC021
DD00P5LC201
DD00P5LC241
DD00P5LC221
this comes up

I know L63613-001 is DD00P5LC021
What part numbers do the rest correspond to?
