In general, the term Thin Film Diode (TFD) may refer to any diode produced using thin film technology.
Within the flat panel display industry TFD more often refers to thin film bi-directional diodes, also known as metal-insulator-metal (MIM) TFDs or nonlinear resistors. Bi-directional MIM TFDs have very low current flow at low applied voltages, but then begin to conduct electricity above a threshold voltage, of either positive or negative polarity. Owing to this behavior these two terminal devices may be used as a switch. The exact threshold voltage at which a MIM TFD switches on and begins to conduct electricity depends on its physical dimensions, such as thickness of the insulating layer, as well as the physical properties of the materials from which it is made, such as the work function of each metal layer.

Famous quotes containing the words thin and/or film:
“It is remarkable with what pure satisfaction the traveler in these woods will reach his camping-ground on the eve of a tempestuous night like this, as if he had got to his inn, and, rolling himself in his blanket, stretch himself on his six-feet-by-two bed of dripping fir twigs, with a thin sheet of cotton for roof, snug as a meadow-mouse in its nest.”
—Henry David Thoreau (1817–1862)
“I think of horror films as art, as films of confrontation. Films that make you confront aspects of your own life that are difficult to face. Just because you’re making a horror film doesn’t mean you can’t make an artful film.”
—David Cronenberg (b. 1943)
