Abstract:
A plasma display panel includes front glass substrate and rear glass substrate disposed opposite to each other so as to form an image display area and an image non-display area. The image non-display area includes a sealing portion in which glass substrates are sealed at a periphery thereof by a seal layer. At least one of front glass substrate and rear glass substrate has a thickness of 0.5 mm or more and 2.0 mm or less. The seal layer is made of a glass material having a softening point temperature 30° C. through 70° C. lower than the sealing temperature at which the periphery of front glass substrate and rear glass substrate are sealed by the seal layer.
Abstract:
Disclosed is a multi-typed plasma display panel for preventing internal penetration of a seal line by forming a barrier rib in a vertical direction, in a horizontal direction or in both directions. In the multi-typed plasma display panel, a barrier rib is formed according to a cross-section in a vertical direction, in a horizontal direction or in both directions so that a seal line of the cross-section is prevented from being penetrated internally. In the horizontal direction, an auxiliary barrier rib may be further formed outside the barrier rib. Additionally, a dielectric of the rear panel is removed as large as an area separated from the cross-section in a predetermined distance so that the seal line may be formed in a condition where a glass is exposed.
Abstract:
A plasma display panel (PDP) having a front substrate structure (first substrate structure) and a back substrate structure (second substrate structure) arranged so as to be opposed to each other via a discharge space is manufactured in the following manner. A sealing member arranged in a frame shape so as to surround outside of a barrier rib formation region where barrier ribs partitioning a discharge space are arranged and a plurality of supporting members arranged in a region between an outer periphery of the barrier rib formation region and the sealing member are formed, respectively. The supporting members are made from material having a softening point higher than that of material for the sealing member, the height of the supporting members is made higher than that of the barrier ribs, and the height of the sealing member is made higher than the height of the supporting members.
Abstract:
A plasma display panel includes a front plate and a back plate spaced from and facing each other with a barrier rib therebetween, the front plate and the back plate each having a long side and a short side. A first sealant is at the long side between the front plate and the back plate and a second sealant is at the short side between the front plate and the back plate to seal a discharge space divided by the barrier rib between the front plate and the back plate. A first spacer is in the first sealant and a second spacer is in the second sealant, the second spacer having a smaller volume than the first spacer.
Abstract:
A plasma display panel having a structure for reducing manufacturing costs and the failure rate of terminal portions of discharge electrodes. The PDP includes: a substrate and a barrier rib structure configuring a plurality of discharge cells. Discharge electrodes include discharge portions, terminal portions, and connection portions connecting the discharge portions with the terminal portions. A sealing member seals the discharge cells. A frit seals the substrate and the sealing member. At least one frit guide restricts the spreading of the frit. A phosphor layer is inside each of the discharge cells. A discharge gas is sealed in the discharge cells.
Abstract:
A PDP with superior light-emitting characteristics and color reproduction is achieved by setting the chromaticity coordinate y (the CIE color specification) of light to 0.08 or less, more preferably to 0.07 or less, or 0.06 or less, enabling the color temperature of light to be set to 7,000K or more, and further to 8,000K or more, 9,000K or more, or 10,000K or more. The PDP is manufactured by a method in which the processes for heating the fluorescent substances such as the fluorescent substance baking, sealing material temporary baking, bonding, and exhausting processes are performed in the dry gas atmosphere, or in an atmosphere in which a dry gas is circulated at a pressure lower than the atmospheric pressure. This PDP is also manufactured by: a method in which after the front and back panels are bonded together, the exhausting process for exhausting gas from the inner space between panels is started while the panels are not cooled to room temperature; or a method in which after the front and back panels are temporarily baked, the process for bonding the panels is started while the panels are not cooled to room temperature. This reduces the time and energy required for heating, resulting in reduction of manufacturing cost.
Abstract:
A plasma display panel reduces noise caused by the formation of minute gaps between the first substrate and the second substrate. The plasma display panel includes a first substrate and a second substrate opposing one another with a predetermined gap therebetween, and a sealant formed on opposing surfaces of the first substrate and the second substrate. The sealant is formed around outer circumferential areas of the first substrate and the second substrate to seal the first substrate and the second substrate together. The sealant is formed of regions having a first width of substantially the same size and of regions having a second width greater than the size of the first width.

Abstract:
A plasma display panel includes a first substrate and a second substrate disposed opposite to each other and having a plurality of discharge spaces therebetween forming a display region for implementing images. Display electrodes are provided in lateral sides of the discharge spaces and extend in a first direction. Address electrodes extend in a second direction crossing the display electrodes. A dummy cell region and a frit region are provided outside of the display region. The frit region includes a first frit formed on a periphery of the first substrate, a second frit formed on a periphery of the second substrate, a dielectric layer disposed between the first substrate and the second substrate and covering the display electrodes, and electrode terminals drawn out from the display electrodes to an edge of the first substrate and the second substrate.
Abstract:
A plasma display panel having a display region that includes discharge cells defined by barrier ribs and a non-display region formed outside the display region. The non-display region includes dummy barrier ribs. The ends of the dummy barrier ribs adjacent the sealing line and the sealing line itself define a gap with a size that is greater than a maximum error range for forming the sealing line and may be equal to or smaller than 140% of the maximum error range. The use of dummy barrier ribs can effectively eliminate a noise source otherwise formed outside the display region.
