Abstract:
In a display panel utilizing gas discharge, ultraviolet rays which are generated at discharge excite fluorescent bodies facing a gas discharge space and the display is effected by the luminescence of the fluorescent material in response to said rays. The fluorescent bodies are surrounded by a dielectric layer having attenuation characteristics against ultraviolet rays. These fluorescent bodies are formed in every discharge region of the plasma display panel. Thus, if the radiation of the luminous body of the display panel utilizing gas discharge diffuses in all directions, its effect does not reach the fluorescent material of adjacent fluorescent bodies and the problem of cross talk can be resolved.

Abstract:
A plasma display panel in which two transparent base plates are assembled together to define a discharge gas space therebetween. On each transparent base plate, a plurality of strip-like main electrodes are provided and a dielectric layer is formed to cover them and, further, third electrodes are each provided between adjacent ones of the main electrodes. The two transparent base plates are assembled together in opposing relation to each other in such a manner that their main electrodes and third electrodes are disposed substantially perpendicuar to each other in the form of a matrix. By impressing a voltage to selected ones of the main electrodes of the both transparent base plates, a discharge spot is produced at their intersecting point to provide a display. The discharge spot becomes enlarged or reduced or extends in a certain direction according to the polarity of a voltage impressed between the third electrodes of both transparent base plates and to the selection of the third electrodes to be supplied with the voltage. The discharge spot can be shifted in either direction of the row and column of the matrix.
Abstract:
A multiple-character display device in which characters are displayed by selective energization of electrodes in sets, with one set of electrodes being provided for each character. Corresponding electrodes in different character sets are interconnected by conductors which are interwoven through spaces between electrodes in the character sets to form continuous paths, thus eliminating the need for external connections for each electrode of each character. Two embodiments of character sets are disclosed, with one embodiment employing a two-stage mode of operation.

Abstract:
An electroluminescent display device formed by superimposing a first substrate upon a second substrate, forming a cell between the surfaces of the two substrates. A common transparent electrode is deposited on the outside surface of one of the two substrates overlying the entire cell formed by the superimposed substrates. A conductive pattern electrode, having a desired configuration, is placed in intimate contact (e.g., pressure contact) against the outside surface of the other substrate. Information is displayed by applying an alternating voltage of sufficient magnitude and frequency between the two electrodes, resulting in the ignition of an excitable gas contained within the formed cell, the illumination produced corresponding to the configuration of the conductive pattern electrode. The conductive pattern electrode is removable, since it is retained against the outside surface of the cell only by a pressure contact; therefore, the type of information to be displayed can be easily varied simply by removing the conductive pattern electrode and placing another in its place. The various designs of removable electrode patterns which can be employed are endless and can encompass Arabic numerals, alphabetic characters, and other designs.
Abstract:
A vacuum flat panel display has a plurality of associated pixels each having a phosphor and nanotubes and a surrounding control frame. When a pixel voltage is negative relative to the frame then a plurality of electrons emitted by the nanotubes are attracted to the frame whereby electrons strike gas atoms in transit to the frame and produce ions and additional electrons; wherein said ions returning to the pixel result in phosphor illumination. The invention is also a process for illuminating a phosphor in a flat panel display comprising: a plurality of associated pixels each having a phosphor and nanotubes; applying a pixel voltage negative relative to a frame; attracting to the frame a plurality of electrons emitted by the nanotubes; whereby electrons strike atoms of a gas in transit to the frame producing ions resulting in phosphor illumination.
Abstract:
A vacuum flat panel display including: a plurality of electrically addressable pixels; a plurality of thin-film transistor driver circuits each being electrically coupled to an associated at least one of the pixels, respectively; a passivating layer on the thin-film transistor driver circuits and at least partially around the pixels; a conductive frame on the passivating layer, said frame and pixel area coated with an insulator; and, a plurality of cathode emitters are deposited on the coated frame while phosphor is deposited on the coated pixel; wherein, exciting the cathode emitters and addressing one of the pixels using the associated driver circuit causes the emitted electrons to induce one of the pixels to emit light. By introducing a noble gas or mixture, and a ML layer having a DC, AC or pulsed voltage applied thereto, one creates a plasma to form a sheath boundary at the insulator causing electron multiplication and increased illumination.
