Mylar ribbon connection cables, with gold plating ends and silicon block. Question?

I have noticed that most mylar connectors have a thin long silicon block mounted somewhere near the middle of the strip.

The mylar connectors I'm meaning are on the flatscreen TV's LED screen mostly.



What is that silicon block/strip actually for? What does it do? I'm guessing its some sort of suspressor of sorts.
Sorta like a capactor, it probably just irons out the electrical signal along the pathway.

But I had a look under a magnafying lens and I think I may have seen Gold wire connectors on its edge where it touches the mylar ribbon. I'm not 100% sure though.

There also seems to be a similar tiny gold wires on the inkjet printers printing head. The printer head looks to be silicon too.
There are several different printer heads, one looks like a silicon block, another looks like a white ceramic block, and others have the printing head on the ink reservior.
But there seems to be the thin Gold wires connecting them up to the mylar ribbon cable.

On the HP printer cartridges, the ribbon mylar has gold plated connections on it. Often when I use a thin tweezer en to rip the mylar off, the Gold connections stay stuck the the plastic cartridge. The gold seems to be solid, like when I fo peel it off, its Gold on both sides.
A while ago I heated up the plastic mylar strip to distort it and all the Gold tracking stayed in place, while the plastic lifted off the gold tracking.
I have seen a different sort of setup on those same cartridges, they did have a 'Gold plating on copper' tracks on the mylar.

Basicly, what's the silicon block do?
Are they connected to the mylar with Gold wires?
Do some printer cartridges have solid Gold connectors/tracks on the mylar ribbon?
Do some printer head have the mylar ribbon connected to the actual head with Gold wires?
