Active matrix

This is a kind of liquid crystal display structure in which switching transistors are attached to each

pixel to control the on/off voltage. It produces a brighter and sharper display with a broader viewing

angle than a passive matrix display. Also refer to TFT (thin film transistor).

Amorphous silicon (a-Si)

A semiconductor material that is used to make the thin film transistors (TFTs) layer of an active

matrix LCD.
