anisotropic strip LCD zebra

Image
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.

The Physics of Electric Guitar Pickups Electric guitar pickups are devices that are used to create an electric current corresponding to the mechanical vibration of the steel strings on a guitar. Electric guitar pickups are often considered to be similar in operation to microphone, but pickups and microphones are, indeed, different devices. A microphone has a small diaphragm that is vibrated by sound waves, a permanent magnet, and a wire coil that is attached to the diaphragm and moves inside the magnetic field of the magnet. An electric guitar pickup, on the other hand, has the coil wound around the permanent magnet and a steel string that moves within the magnetic field of the permanent magnet. In both cases, a change in magnetic flux (a measure of the magnetic field strength) through the coil induces a current in the coil. The major difference between the two is that only the vibration of the steel strings is picked up by the electric guitar pickup, not sound. This leads to some dist
