Electronic fluorescent display

In a cathodoluminescent display device, spacer elements are used to provide rigid mechanical support between the face and back plates when the chamber of the device is evacuated so that thin face and back plates may be used even for large-screen displays. The spacer support includes a spacer plate having holes therein for passage of electrons between the anode and cathode where a predetermined small number of one or more pixel dots corresponds to and spatially overlaps one hole, thereby reducing crosstalk. Shadow-reducing electrodes are employed on the back plate and spacer members alongside the cathode to cause the path of electrons from the cathode to the anode to bend towards the spacer members in order to reduce shadows caused by the presence of the spacer members. Various configurations of the two or three sets of grid electrodes may be employed to improve resolution and focusing. A linear array of cathode filament segments is used instead of one long integral cathode wire where the ends of the segments overlap to eliminate any visible gaps caused by the end portions of the segments being at lower temperatures than intermediate portions.

Method for displaying frame of pixel information on flat panel display

A flat panel display (300) having a spacer (351) situated between a faceplate structure (320) and a backplate structure (330) is partitioned into (a) a pair of spacer-adjacent regions (303 and 304) adjacent to, and on opposite sides of, the spacer and (b) a pair of spacer-charging regions (302 and 305) respectively adjacent to, and further away from the spacer than, the spacer-charging regions. Each of the spacer-adjacent and spacer-charging consists of one or more pixel rows. Instead of activating the pixel rows sequentially during a frame of pixel information, the pixel rows are activated according to the order that arises when both of the spacer-charging regions are activated after activating the two spacer-adjacent regions.
