There are face plate displays on car audio ( e.g.. CD players ) that
when you disassemble
the faceplate there are no hard wire connections between the display
and the printed circuit board.
I don't know what you call it but the bottom of the display has like
two rubber strips that press
against dozens of carbon points on the printed circuit board, this is
how the display operates.

You have a similar display setup on Fluke 77 meters ( I don't know
about other Fluke
Meters ). How exactly does this rubber strips ( if they are rubber
strips ? ) connecting to
carbon points work? What are the strips called ? What is this type of
connection called.
Can you clean the display rubber strips with rubbing alcohol if only
part of the
display works. Physically pressing on the display produces different
effects on the display.

Your help appreciated.

Thanks in advance

Zebra stripe connectors. There are conductive channels vertically in them.

You can clean with alcohol, will fix most irratic display problems..
