Abstract
The device is a display apparatus which includes an array of tiles. Each tile includes an array of phosphor pixels sealed between an upper sheet of glass and a metallic anode film. Row control gates form an electrode for each row of pixels. Column electrodes are directed to apertures in the row control gates which are positioned under the electrodes. By maintaining the metallic anode film at a high positive potential, and the electrodes at a positive potential, the pixels can be selectively displayed by selectively holding the column electrodes to a zero potential thereby causing electrons to be projected from the column electrode to the metallic anode film.
