Abstract

This publication relates to a plasma display apparatus for generating images to be viewed from the front or rear of a panel without inverting the image or without loss of intensity. In conventional AC plasma displays, parallel conductor arrays are formed on a pair of glass plates with the conductor array disposed substantially orthogonally to each other. The conductors are overcoated with a dielectric and a protective layer and sealed about their edges, and the glass container is filled with an ionizable gas. By selective energization of conductors, a discharge tube placed between the conductors and the resulting ionization produces a visible display.

Dual Face Plasma Display Device

This publication relates to a plasma display apparatus for generating images to be viewed from the front or rear of a panel without inverting the image or without loss of intensity. In conventional AC plasma displays, parallel conductor arrays are formed on a pair of glass plates with the conductor array disposed substantially orthogonally to each other. The conductors are overcoated with a dielectric and a protective layer and sealed about their edges, and the glass container is filled with an ionizable gas.

By selective energization of conductors, a discharge tube placed between the conductors and the resulting ionization produces a visible display. Plasma display devices in which an image can be divided, whereby portions of a display may be viewed on one side and separate portions on the opposite side, are known in the art.

A modified plasma psnel structure is used to provide a two sided display in the following manner. Referring to the figure, three glass plates, labeled A, B and C, are separated by spacers to form two separate gas chambers. The center plate B contains a black dye pigment to prevent interference between front and rear displays. Plates A-B and B-C function as two independent gas panels which are individually addressable. The upper or front panel includes plate A, conductors or electrodes D, preferably chrome copper chrome on the surface thereof, dielectric layer E and conductors F. A mirror image of this display...
