Abstract
An LCD micro display for generating an image of a video signal includes a matrix of pixels arranged in a plurality of rows and a plurality of columns, which are selectively energized to create the image. The rows are connected to a row select circuit for energizing each of the rows in accordance with a first predetermined sequence. The columns are coupled to a column select circuit coupling the video signal to each of the columns in accordance with the second predetermined sequence. The column select circuit includes a plurality of video switches, each of which include a high speed current mirror level shifter for shifting the control signal from a first potential to a second higher potential. A transmission gate couples the video signal to one of the columns upon receipt of the higher potential control signal.
