Abstract

A method for using non-selected anode electrodes as electron 'sinks' for capturing electrons that have been emitted from an electron-emitting cathodic element and which do not land on selected anode electrodes in cathodoluminescent flat panel displays. The non-selected anodes are set to a low positive potential relative to the cathode such that electrons are more uniformly directed towards both selected and non-selected anode electrodes, and the number of electrons scattered from non-selected anode electrodes are reduced significantly.
