anisotropic strip LCD zebra
The anisotropic strip on the LCD is technically known as an elastromeric connector, but usually referred to as a zebra strip. If you examine it closely under a strong magnifying glass or a low power microscope, you’ll see alternating bands of conductive and insulating material, usually something like graphite loaded rubber for the conductive material and unloaded rubber for the insulating material. The graphite loaded rubber gives that portion of the strip a darker colour. Thus, you have alternating light and dark bands, similar to what a zebra looks like.
