Abstract:
It is sought to improve the image contrast of plasma panel type display screens. A plasma panel comprises a front plate (D1) bearing photoluminescent elements (LB1, LV1) constituted by grains (GL1, GLn) of luminophor material. According to one characteristic, the grains (GL1, GLn) have a diameter of less than 1.5 micrometer. This, in relation to the prior art, constitutes a substantial reduction of the diameter of the luminophor grains, which leads to reducing the coefficient of reflectance, the result of which is an improvement of the contrast of the image.

Then, an AC voltage necessary for maintaining a discharge is applied between the memory electrodes (3a), (3b) of the pair of memory elements (Ma), (Mb).
Abstract:
A one sided a.c. plasma panel comprises a glass substrate encapsulated within a pair of glass plates dividing the panel into two interconnected chambers. One set of conductor arrays originate within the rear aperture are are conducted through display vias to circular electrodes in the front aperture. The second set of electrodes comprise annular rings which are concentric and coplanar with the circular electrodes. This configuration limits discharge spread on the display surface, permitting increased resolution without crosstalk. Multicolor capability is provided by the combination of ultraviolet sensitive phosphors on the inner surface of the front faceplate and an ultraviolet emitting gas within the plasma panel.
Abstract:
A structure of a panel which can be thinned down to about a panel thickness of a PDP and a manufacturing method thereof are provided. A gas filling hole is provided to a surface of a rear glass substrate of a PDP, the surface coming in contact with a front glass substrate of the PDP. Vacuuming and filling of a discharge gas are performed through the gas filling hole. After filling of the discharge gas, a mechanism for lifting solder iron up and down and supplying solder provided inside a chamber inserts a tip of an ultrasonic soldering iron into the gas filling hole to start supplying a solder which is a material for a plug sealant. When a series of forming steps of the plug sealant are finished, the ultrasonic soldering iron is retreated before the solder is solidified to finish formation of the plug sealant.
