ABSTRACT:
A circuit for use with an LCD display wherein the LCD display contains a first number of pixel columns and a second number of pixel rows on a substrate is provided. The circuit comprises a plurality of row select driver circuits corresponding to the number of pixel rows for electrically energizing the pixel rows. The row select driver circuit is deposited on the LCD display substrate and an output of each of the row select driver circuits is electrically connected to a corresponding pixel row and to a successive row select driver circuit as an activating input. Switching apparatus external to the LCD display and having leads electrically connected to the row select driver circuits is also provided for electrically switching the row select driver circuits such that each pixel row is sequentially energized. A corresponding method is also disclosed.
