Abstract
Flat panel displays are provided including protection from electrostatic discharge (ESD) during manufacture and thereafter. At least one ESD guard ring is provided to protect the active elements of the display from the potential discharge between the row and column lines. An internal ESD guard ring is coupled to the row and column lines via shunt transistors. An external ESD guard ring is coupled to the row and column lines via a resistance. Both of the guard rings can be provided; however, the external guard ring is removed prior to completion of the display.
