If your technology is very complex, you have 2 challenges:

1. Still explain the principle of the technology in a simple way
2. Show that the incredible complexity is an asset that is hard for competitors to copy

Don't mix the two. If you cannot resist and make the explanation of the basic idea behind your technology complex, people won't get it. If you oversimplify things and hide the complexity, people will think that this is something obvious and not worth investing in.

You need to separate (sets of) slides.
