Link to a video that made me understand how screens are mounted. I can have as many as I want in sizes given by this manufacturer in different combinations so they fit my walls where needed. They’re low in energy use LED screens.

I was mainly looking for the thickness of this mechanism to draw on my plans.

Other links I had a look at.

This one has even smaller panels that can be curved.
