    Abstract: The specification describes a flat panel gaseous discharge display device in which the display illumination is formed at least in part by luminescence resulting from excitation of an appropriate phosphor by low energy electrons drawn from a glow discharge. To provide scan, the discharge is either itself moving in stepwise fashion between discrete cells or is a secondary discharge primed by a scanning discharge and triggered by the display information signal. Varying the current through the phosphor produces gray scale. Illumination from the gaseous discharge may be mixed with the phosphor for color balance and increased brightness. The phosphor can be divided into color stripes with means for selective energization of the stripes to form a color display.

    Abstract: The beam index concept for color television display tubes has been known for some time, and although this color display approach is fundamentally more attractive than the commercially favored three-gun shadow mask tube, techniques for producing the indexing signal have been inadequate. According to the invention, index signals in a single-gun tube with horizontal phosphor stripes, operating in a line (color)-sequential mode, are generated by UV phosphor bars spaced uniformly along each color stripe but with different spacings for each color. As the beam scans a stripe, an optical signal is generated with a frequency corresponding to the periodicity of the phosphor index bars. The optical signal is detected with a UV detector. The amplitude of each frequency will indicate the beam size and vertical position. The index signals are fed to a signal processor which, by simple filtering, will generate error correction signals which are in turn fed to the deflection circuit to correct the beam position. The use of the optical index signal ensures isolation of the beam index signal from the video.

    Abstract: A new mechanism for bubble domain generation permits nucleation with less power than previously expected. A nucleation pulse of a particular form enables the mechanism to be employed without reducing the effective difference between the propagation and nucleation thresholds which impart stability to bubble arrangements.
