"An a-Si, p-Si, or CdSe used as a switch to a charge storage device beneath
each subpixel of an AMLCD.. A type of LCD flat-panel display screen, in
which each pixel is controlled by from one to four transistors. The TFT
technology provides the best resolution of all the flat-panel techniques,
but it is also the most expensive. TFT screens are sometimes called
active-matrix LCDs."
