Definitions
- PLANE SURFACE DISCHARGE PLASMA DISPLAY PANEL Inventors: Norihiko Nakayama, Kobe;
- FIG 60 PATENTEDMAY 14 I914 3.811.061
- This invention relates to discharge plasma display apparatus in which discharge electrode pairs are provided on the same base plate while being insulated from each other.
- a glass plate having bored therein apertures forming discharge cells is interposed between a pair of glass base plates; a mixture gas composed of neon Ne and nitrogen N is sealed within the discharge cells; electrodes are provided on the outside of each glass base plate in directions perpendicular to 'each other; and a discharge is produced to radiate in the discharge cell at the intersecting point of selected electrodes.
- the conventional plasma display panels are advantageous in that since the cells each forming a discharge region are isolated from one another, no interference occurs between adjacent ones of them and in that since the apertured glass plate interposed between the pair of the glass base plates serves as a spacer of the latter, the opposing electrodes can be maintained at the same distance.
- the prior art display panels are defective in that evacuation and sealing of the discharge gas are difficult.
- the glass base plates are required mechanically strong enough to withstand the pressure difference between the sealed gas pressure and the atmospheric pressure, they are unduly thick.
- each glass base plate leads to an increase in the distance between the opposing electrodes, which results in a defect that a high firing voltage is required.
- the glass base plates themselves are also a little curved, so that the characteristics of the respective discharge regions cannot be made uniform with case. This presents a problem especially in the construction of large display panels.
- discharge electrode pairs are provided on a glass or like base plate; a solder glass or like dielectric layer isformed overlying'the discharge electrodes; a glass or like cover is mounted on the dielectric layer to provide a discharge gas space therebetween the periphery of the cover being sealed; an ionizable gas such as neon or the like is sealed within the discharge gas space; and a display is provided by a discharge caused between the respective discharge electrode pairs on the dielectric layer.

- the dielectric layer 5 holds the charge produced by discharge to provide a memory function and the discharge spot is maintained by the subsequent sustain voltage as is the case with the conventional plasma display panel.
- the discharge gaps can be accurately formed by printed circuit techniques and are formed on the same base plate, so that even if the base plate 1 is curved, the discharge gaps do not change. Since the cover 6 is only to form the discharge gas space 7, the degree of parallelism of the electrodes with the base plate 1 is not important and the characteristics of the discharge cells formed with the discharge gaps become uniform and the fabrication of the display panel becomes extremely easy.
- the electric field in the discharge gas space 7 is related to the thickness of the dielectric layer 5 and the distance between the discharge portions 2a and 4a, that is, the discharge gap length; but, by selecting the thickness of the dielectric layer 5 less than about one half of the discharge gap length, the discharge spot can completely be produced in the discharge gas space 7.
