1. A method of manufacturing active matrix display backplanes and displays therefrom, comprising:

  • providing a substrate;

    forming a pattern of pixels on said substrate;

    forming a plurality of row and column intersecting pixel activation lines, interconnecting substantially all of said row lines to one another and substantially all of said column lines to one another;

    forming an outer electrostatic discharge guard ring on said substrate coupled to said interconnected row and column lines via a resistance to provide protection from electrostatic discharges between said row and column activation lines during manufacture of the displays; and

    removing said outer guard ring and row and column interconnections prior to completion of the display.
