Abstract:
A spacer for planar panel display; a process for producing the same; and a planar panel display. When the degrees of expansion are much different between the spacer for planar panel display and the face plate and back plate, straining of planar panel display, nonalignment and inclination of spacer, etc. are likely to occur to result in deflection of emitted electrons. These are prevented by the use of a product of sintering of composite ceramic composed of, mixed together in specified ratio, Al2O3 (alumina), TiC (titanium carbide), MgO (magnesium oxide) and TiO2 (titanium dioxide). There is provided a spacer for planar panel display comprised of a sintering product containing Al2O3, TiC, MgO and TiO2 which sintering product contains MgO in an amount of 35 to 55 wt.% based on the total weight of Al2O3, TiC, MgO and TiO2.

An electron-emitting element consisting of element electrodes (2, 3), conductive film (4) and an electron emitter (5) is provided at each intersection of the row wires (8) and column wires (6). Spacers (9) are placed on some of the row wires (8). The column wires (6) are connected with regulated current sources (221a, 221b, 221c) capable of supplying desired current.

Abstract:
A flat panel display having a backplate structure (330), a faceplate structure (320), and a spacer (340) situated between the two plate structures is configured so that the electric potential field along the spacer approximates the potential field that would be present at the same location in free space, i.e., in the absence of the spacer, between the two plate structures. Consequently, the presence of the spacer does not significantly affect the trajectories of electrons moving from the backplate structure to the faceplate structures. Alternatively, the spacer is arranged to produce electron deflection that largely compensates for undesired electron deflection which occurs during earlier electron travel from the backplate structure to the faceplate structure. The net electron deflection is small.
