LCD Connections

Hi,

I have 2 LCD's which have connection problems. One is in a
multimeter & the other in a keyboard.

The multimeter has a ribbon cable feeding the display which
somehow originally adhered to it.

The keyboard display uses a 'spongy' material, conductive in
the appropriate places, which although has a little pressure
on it, also used to adhere to the display.

There seems to be no evidence of any adhesive on either
display, which one would think would act as an insulator
anyway. How the connections originally stuck to the displays
has got me tricked & so has how to fix them!

Any ideas?

Cheers, Mark
