Abstract
An electrode (12 or 30) of an electron-emitting device has a plurality of openings (16 or 60) spaced laterally apart from one another. The openings can be used, as needed, in selectively separating one or more parts of the electrode from the remainder of the electrode during corrective test directed towards repairing any short-circuit defects that may exist between the electrode and other overlying or underlying electrodes. When the electrode with the openings is an emitter electrode (12), each opening (16) normally extends fully across an overlying control electrode (30). When the electrode with the openings is a control electrode (30), each opening (60) normally extends fully across an underlying emitter electrode (12). The short-circuit repair procedure typically entails directing light energy on appropriate portions of the electrode with the openings.
