Abstract
Abstract An improved luminous radiation panel apparatus of the type in which no separator is used between two substrates and which is thus simple to manufacture, free from erroneous discharge, longer in life and capable of producing a stable discharge. Furthermore, the apparatus has high resolution and brightness and there is no possibility that the excitation of a selected phosphor simultaneously excites the adjacent phosphors. The apparatus is adapted to make a display in color and is suited as a display device, particularly as a television apparatus or character display device.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A panel luminous radiation apparatus of the type in which light is produced by a discharge through a space containing a gas at the respective intersections of a plurality of electrodes disposed on a substrate and another plurality of electrodes disposed on another substrate to oppose and intersect one another with said first-mentioned plurality of electrodes, wherein a plurality of phosphor stripes or dots are applied at least to one of said substrates at positions opposite to said plurality of electrodes on said one of said substrates, and a thin sheet of glass capable of transmitting ultraviolet ray therethrough is applied to said phosphors.
Claim 2
Dependent Claim
104 words
A panel luminous radiation apparatus of the type in which light is produced by a discharge through a space containing a gas at the respective intersections of a plurality of electrodes disposed on a substrate and another plurality of electrodes disposed on another substrate to oppose and intersect one another with said first-mentioned plurality of electrodes, wherein a plurality of phosphor stripes or dots are applied at least to one of said substrates at positions opposite to said plurality of electrodes on said one of said substrates, and a thin sheet of glass capable of transmitting ultraviolet ray therethrough is applied to said phosphors.
Claim 3
Dependent Claim
33 words
A panel luminous radiation apparatus according to claim 1, wherein a ultraviolet ray preventive coating is disposed between said plurality of electrodes arranged on said glass sheet on said one of said substrates.
Claim 4
Dependent Claim
40 words
A panel luminous radiation apparatus according to claim 1, wherein one polarity side of said plurality of electrodes on said glass sheet comprises a transparent electrode, and a conductive metallic coating is disposed on a portion of said transparent electrode.
