Abstract:
A plasma display panel is disclosed. The plasma display panel includes a front substrate, a scan electrode and a sustain electrode positioned parallel to each other on the front substrate, an upper dielectric layer positioned on the scan electrode and the sustain electrode, a rear substrate positioned to be opposite to the front substrate, and a barrier rib that is positioned between the front and rear substrates and partitions a discharge eel The upper dielectric layer includes a glass-based material and a cobalt (Co)-based material as a pigment. The barrier rib includes lead (Pb) equal to or less than 1,000 ppm (parts per million).
Abstract:
A method of manufacturing a plasma display panel having a first substrate, a second substrate opposite to the first substrate, partitions that define a plurality of discharge spaces between the first and second substrates, and a sealing frit that is sandwiched between the peripheries of the first and second substrates so as to seal the space between the first and second substrates. This method is characterized by forming a sealing frit (22) on either of first and second substrates and partitions (15, 19) on the second substrate, combining the first and second substrates by providing a spacer (20) that is made of the same material as that of the sealing frit between the first substrate and the tops of the partitions, pressing the peripheries of the first and second substrates from outside using a press member (21), heating the first and second substrates up to or higher than the softening point of the sealing frit while evacuating the space between the substrates, and, after the evacuation, introducing a discharge gas between the panels.
Abstract:
Espaceur destiné à maintenir un espace entre deux substrats formés de feuilles de verre, plus particulièrement un espace d'épaisseur limitée, généralement inférieure à quelques millimètres, sur toute la surface des substrats en feuilles, dans un dispositif tel qu'un écran de visualisation, un vitrage isolant sour vide ou une lampe plane, la surface dudit espaceur étant au moins en partie électroniquement conductrice, caractérisé par le fait que ledit espaceur est formé d'un cœur ne présentant pas de conductivité électronique, dont la forme et le matériau constitutif sont choisis pour permettre d'assurer la tenue thermo-mécanique des substrats dans le dispositif final, ledit cœur étant revêtu au moins en partie d'au moins une couche d'un verre présentant une conductivité électronique de 10 -13 à 10 ohm -1 .cm -1 à 50 °C.
Abstract:
The display panel has a glass backplate (1) a first surface of which is provided with barrier ribs (3) of glass frit. Electrodes (5) are present between the ribs (3). A front member (10) rests on the barrier ribs (3) and is sealed to the backplate (1). The front member (10) has electrodes (11) which extend transversely to the ribs (3). The glass frit of the ribs (3) mainly consists of ZnO, B2O3 and V2O5 and has a minor content of SiO2, PbO and/or CuO, and BaO and are mechanically strong. The glass frit combines a relatively small thermal coefficient of expansion and a relatively low sintering temperature, which makes the frit particularly suitable for use with a backplate (1) of borate glass, particularly an alkali-free borosilicate glass.
Abstract:
A plasma display device having a composite back plate including a metal core (110) and a ceramic barrier rib structure formed using a green ceramic tape (112) which is a combination of two glasses, a primary glass which flows back during firing and a secondary glass that has a relatively high thermal coefficient of expansion. These glasses are combined in proportion to match the thermal coefficient of expansion of the metal substrate.
