Abstract
An active matrix liquid crystal display is provided with one switching transistor connected to each display element. A separate drive circuit is connected to each column of the matrix, each such drive circuit incorporating a buffer circuit which is constructed of an output transistor and three separate switching elements. The buffer circuit transfers a sample of a data input signals to the respective column while requiring reduced power over conventional drivers.
