Abstract:
A flat panel display includes a front substrate, a rear substrate parallel to and spaced apart from the front substrate for forming a gap between the front and rear substrates. A display area is positioned on the surface of the rear substrate facing the front substrate. The flat panel display further includes a plurality of barrier ribs positioned on the display area of the rear substrate, a first channel rib positioned on at least two sides of the display area of the rear substrate, and a second channel rib spaced from the first channel rib by a predetermined distance. The first channel rib and the second channel rib form a sealing channel. A sealing frit fills the sealing channel to seal together the front substrate and the rear substrate.
Abstract:
A flat display panel and a flat display device are realized in which sealing layers can sufficiently alleviate and absorb strain stress between two substrates which is caused by internal stress of the substrates during sealing process and after cooling process, and which can cancel out disadvantages of an amorphous glass paste and a crystallized glass paste, and a flat display panel manufacturing method is realized which can prevent application of excessive or insufficient pressure to the sealing layers. In a flat display panel formed with at least two substrates (1A) and (1B) sealed together, sealing layers (21a) are formed as a stacked structure containing a plurality of layers or formed in a region containing a plurality of stripes, so as to obtain a stable seal. The sealing layers (21a) are formed of a crystallized glass paste (2A) and an amorphous glass paste (2B). A pressing force applied in the sealing process is positioned near the sealing layers and inside the position of the sealing layers.
Abstract:
Disclosed is a plasma display panel that enables providing stabilized discharge characteristics of the panel. In the regions on a rear glass substrate inside a sealing layer and outside a display region, formed are second walls having a plurality of discontinuous portions and extending substantially in parallel to the sealing layer, and third walls opposed to the discontinuous portions of the second walls substantially in parallel to the sealing layer.
Abstract:
A plasma display panel and a method for fabricating the same are disclosed, in which the fabricating process time of the plasma display panel can be reduced, characteristic and performance of the panel can be prevented from being reduced, and the panel can be prevented from being damaged. Also, a panel structure is not changed by external pressure variation. The method for fabricating a plasma display panel includes the steps of: depositing a first adhesive along a predetermined area outside an active picture of a first substrate; depositing a second adhesive outside a portion where the first adhesive is deposited, to have a predetermined interval from the first adhesive; depositing a sealant to align with upper portions of the first and second adhesives; depositing an adhesive outside a portion where the second adhesive is deposited, to have a predetermined interval from the second adhesive; aligning a second substrate on the first substrate; and attaching the first and second substrates to each other under a predetermined pressure.
Abstract:
Plasma display panels of the prior art are prone to cross talk leading to unstable image. The present invention provides a gas discharge panel comprising a first panel substrate 104 having first electrodes 24, a second panel substrate 108 having second electrodes 23 opposing the first panel substrate 104, a sealing portion provided between peripheries of the two substrates for forming a gas discharge space 112 between the first and second panel substrates 104, 108 and division walls 30 provided on the second panel substrate 108 for dividing the gas discharge space 112, wherein ridges of the division walls 30 are bonded onto the inner surface of the first panel substrate 104 by a frit glass 31.
Abstract:
A method for forming a back panel for a plasma display includes preparing a green ceramic tape having a temperature coefficient of expansion (TCE) which matches the TCE of a metal core. Barrier ribs are formed on the back panel by embossing or scribing the green ceramic tape. The formed green ceramic tape is then bonded to the metal core. Finally, the bonded formed green ceramic tape and the metal core are cofired to form the back panel.
Abstract:
A discharge display device wherein a gas-tight space defined by two plates and a sealing member is divided into a plurality of discharge chambers by partition walls formed on one of the two plates, and height adjusting layers are interposed between end faces of the respective partition walls and an inner surface of the other plate. Each height adjusting layer is formed from a material which has a softening point not lower than that of the sealing member and which is softened at a sealing temperature at which the two plates are bonded together by the sealing member. The height adjusting layers, which assure gas-tight separation of the discharge chambers, may replace upper end portions of the partition walls. Alternatively, the partition walls may be entirely formed from the above-indicated material. Also disclosed is a process of fabricating such a discharge display device, wherein height adjusting layers are softened at the sealing temperature when the two plates are bonded together with the melting of the sealing member.
