An active matrix liquid crystal display (AMLCD) is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to light weight, very good image quality, wide color gamut, and response time. The term was first used in 1975 by Dr T. Peter Brody to describe a method of switching individual elements of a flat panel display, using a CdSe TFT for each pixel.[1]
The most common example of an active matrix display contains, besides the polarising sheets and cells of liquid crystal, a matrix of thin-film transistors (TFTs) to make a TFT LCD. These devices store the electrical state of each pixel on the display while all the other pixels are being updated. This method provides a much brighter, sharper display than a passive matrix of the same size. An important specification for these displays is their viewing-angle.
