ABSTRACT:
An electronic display device includes a two-dimensional array of point charge sources, which are aligned with a plurality of apertures defined in a substrate. Associated with each aperture is a set of electrodes, including a focusing electrode, which in effect funnels the ions from the charge source into a narrow stream, and a plurality of displacing electrodes, through which the ion stream can be caused to scan over a small two-dimensional area on a phosphor. Modulating the bias on the focusing electrode can be used to control the ion stream passing through an individual aperture according to image data. The combined action of a two-dimensional array of charge sources and associated control devices can create a single composite image on the phosphor.
