Glossary Glossary A B C D E F G H I J K L M N O P Q R S T U V W X Y Z A 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.
