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.
Aspect ratio

aspect ratio of 4:3 or 5:4. Wide monitors or TVs have an aspect ratio of 16:9 or 16:10.
