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
The width-to-height ratio of the active area of a display. In general, most monitors have an aspect
ratio of 4:3. Wide monitors or TVs have an aspect ratio of 16:9 or 16:10.
