30-pin eDP connector and Laptop LCD Panel

Moderators: chensy, FATechsupport

Can the 30-pin eDP connector be used for a 1920x1080 Laptop LCD using a 30-pin eDP?
Hi,
that is a good question. I'm interested too.

I found Displays like: https://www.sdv-elektronik.de/lp156wf4- ... splay-matt
But i need to know if this is working

Thanks

You can do this but you will have to use a custom kernel to set the timing of the display.

If you want touch, you'll also need to add a driver for this if the touch controller is not one supported by the kernel.

You'll also need to know the LVDS bit allocation applied to each channel for your chosen LCD. It is likely 24 bit as that is most common so will be spread across 3 LVDS channels with the remaining timing signals on the 4th channel.
In my opinion, it is a heavy task to build the own custom kernel.
especially if you want to use android on the T4.

I suspect that most display manufacturers are not interested to corporate with us and get us details about the display and their time rates.
So it's sounds like a try and error session.

Is there a guide to build a new kernel for the oreo android image for T4?

for my project the displayframe uses an 3M micro touch controller and has an option listed for a mainline kernel.

thanks a lot
Hi..most laptop screens use a 30-pin eDP connection. If you would like to use this for one of your projects, you need a controller board for that specific screen. This will give you an HDMI input - which you can use with your Raspberry Pi 3 HDMI output.
