Hello, 

I wanted to use these screen from aliexpress :

It uses MIPI DSI and Touch Screen.

I have no idea yet if touch pins are doubled on both sides. But I don't know how to connect these pins in the devboard which looks like that on the back ...

Any suggestion how should I interpret these pinouts and how to connect on this board ? I am a bit new to this MIPI standard stuff.

    Your LCD seems not pin to pin compatible with LCD connector CN10 and TP connector CN2 on 32F469IDISCOVERY, it may not be supported directly.  You may refer to 32F469IDISCOVERY schematic at https://www.st.com/resource/en/schematic_pack/mb1189-c01_schematic.pdf. thanks!

    I thought MIPI DSI is a standard that is has 30 pins. 
    Which I guess in this screen touch pins are both in 7 pin connector and 30 pin connector which is weird ? I guess.

    But nonetheless I thought MIPI DSI is a fixed standard which has predefined number of pins.
