Recently I have taken an old MP4 apart so I could maybe reuse some of it's parts. One of them is the touchscreen panel, but the big problem is, I don't know the pin layout of it. Is there a way I could figure it out?

After taking some time I have tried some things and could identify 9 pins:
01-(nothing?) 02- 03- 04- 05- 06- 07- 08- 09- 10- 11- 12- 13- 14- 15- 16- 17- 18- 19- 20- 21- 22- 23- 24- 25- 26-Touchpanel Y- 27-Touchpanel X- 28-Touchpanel Y+ 29-Touchpanel X+ 30-LED A Backlight 31-LED K1 Backlight 32-LED K2 Backlight 33-LED K3 Backlight 34-LED K4 Backlight 35-Connected with the C1 36-Linked with 35 37-(nothing?)
I still have the MP4 board which I can hook up on a 3.7V source (battery output) and maybe measure the output of the pins. But even with the measurement I don't know what pin does what. I would appreciate if someone could explain how to analyze the panel and maybe identify some other pins from these pictures:
I have been able to find a similar panel here, but sadly I can't read the language. A user has posted his work there which looks like this:
One more question what I would have is: how can I find out where ground (GND) is? For the most simple analysis I need to be able to connect my sources to the GND pin. Is there a way to figure it out on the panel?
Thank you in advance!
P.S. Sorry if I made some kind mistake, I am new to this part of StackExchange.
