LCD Without Wire Connectors

That rubber strip has a lot of conductive strands that make contact with the gold pads on the circuit board and the contacts on the edge of the LCD display.

Visually, think of it like a strip of corrugated cardboard on edge with little bits of wire in each corrugation. ;-)

It's known as zebra strip. It's a sandwich of hundreds of tiny regular rubber strips, alternated with hundreds of conductive rubber strips. Compared to the sizes of the gold-plated print lozenges that form the connection points, and the spaces between them, several conductive strips will lie on each lozenge, and at least a couple of regular rubber insulating strips, will be in the gaps. When the whole caboosh is tightly fixed together, the conductive strips join the PCB lozenges to the deposited metal connections on the LCD glass.

It's that rubber.

It's made of of axially stacked layers of conductive and non-conductive elastomer. google "zebra strip" for more info.

Thanks for the helpful info, folks. I had never heard of a "zebra strip" and with my eyes there was no visible indication of conductively separated segments on that rubber strip.
