Abstract:
The present invention relates to the field of flash tubes for photographic use, in particular to a flash tube comprising a trigger element for triggering a flash in the flash tube. Accordingly, a flash tube is provided. The flash tube comprises a glass envelope enclosing a gas for use in a flash tube; a first electrode inside the glass envelope; a second electrode inside the glass envelope; and an electrically conductive trigger element being configured to receive a high voltage pulse for at least partly ionizing the gas inside the glass envelope in order to trigg a flash in said flash tube, wherein said electrically conductive trigger element extends along the glass envelope from a first point on the glass envelope adjacent to the first electrode to a second point on the glass envelope adjacent to the second electrode such that a single unified spark stream which bridges the first and second electrodes inside the glass envelope is formed in the at least partly ionized gas adjacent to said electrically conductive trigger element when said electrically conductive trigger element receives the high voltage pulse.
Abstract:
A structure and driving method of a plasma display panel is provided, in which an amount of priming particles within a discharge cell increases to reduce discharge lag of address discharge. The structure of the plasma display panel includes a plurality of sustain electrode pairs successively formed on an upper electrode, a plurality of common electrodes formed one by one between a pair of the sustain electrodes, and a dielectric layer formed on the substrate to deposit the sustain electrodes and the common electrodes. The method for driving the plasma display panel includes the steps of applying a common pulse, which is periodically turned on/off, to the common electrodes, applying a scan pulse to one of a pair of the sustain electrodes, and applying an address pulse to the address electrodes when the scan pulse is applied to the one sustain electrode. Thus, since discharge conditions within the discharge cell can be improved, discharge lag less occurs than the related art plasma display panel.
Abstract:
A plasma display panel (PDP) includes first and second substrates provided in opposition to one another, address electrodes formed on the first substrate, barrier ribs mounted between the first and second substrates so as to define a plurality of discharge cells, phosphor layers formed in the discharge cells, first and second electrodes formed on the second substrate, and third electrodes mounted between the first and second electrodes at positions corresponding to the discharge cells. The first and second electrodes are positioned further from the second substrate than the third electrodes, and a spacing is provided between the first and second electrodes. A method for driving the PDP includes (a) applying a reset waveform to the third electrodes during a reset interval, (b) applying a scan pulse to the third electrodes during an address interval, and (c) applying a sustain discharge voltage alternately to the first and second electrodes during a sustain discharge interval.
Abstract:
A plasma display panel has address properties stabilized. A priming discharge is performed between auxiliary electrodes (18), which are formed on a front substrate (1) and coupled with scan electrodes (6), and priming electrodes (14) formed on a back substrate (2). And on the front substrate (1), a dielectric layer (4) is made thinner in regions corresponding to priming cells (gap parts 13) than in regions corresponding to cell parts (11). As a result, the priming discharge has a wider margin, and a supply of priming particles to the discharge cells is stabilized, whereby a discharge delay during the addressing is reduced, and the address properties are stabilized.

Abstract:
A plasma display panel can reduce a discharge delay in address discharge, thereby performing high-speed addressing in a stable manner. A front substrate (1) and a back substrate (2) are disposed to face each other, and a discharge space (3) is formed and partitioned by barrier ribs (10) so as to form priming discharge cells (17) and main discharge cells (11). A clearance (19) is provided between the barrier ribs (10) of the priming discharge cells (17) and the front substrate (1), and priming particles generated in the priming discharge cells (17) are supplied to the main discharge cells (11) through the clearance (19), whereby a PDP performing high-speed addressing is obtained.

Abstract:
A plasma display panel (PDP) constituting a main part of a plasma display device has a front substrate and a back substrate disposed facing to the front substrate. A discharge gas space is formed between the front substrate and the back substrate. On the surface of the front substrate facing to the back substrate, a scanning electrode and a sustain electrode are disposed. Each of the scanning electrode and the sustain electrode has a transparent electrode made of conductive material and constituting a row electrode via a discharge gap,.and a bus electrode having a low resistance conductive material that is overlapped with a part of the transparent electrode to be electrically connected thereto. A priming electrode, parallel to each electrode, has a low resistance conductive material and is disposed between the scanning electrode of one display cell and the sustain electrode of other display cell adjacent to the one display cell.
Abstract:
In a plasma display panel, cells are disposed in a column direction and in a row direction in the form of a matrix, and electrodes are formed such that, in cells located in each column, a cell has a priming electrode (auxiliary electrode) electrically connected via an interconnection to a scan electrode of a cell at an upper adjacent location. This structure in terms of electrodes allows a write discharge to occur without fail in a reduced scanning period.
Abstract:
On a first substrate provided on a display surface of a plasma display panel, bus electrodes (12a, 14a) in X and Y electrode lines (12, 14) forming a pair of display electrode lines are formed with an Ag material containing a black additive (RuO.sub.2, etc.) by a screen printing. This prevents external light from being reflected at the surfaces of the bus electrodes (12a, 14a) on the display side of an FP substrate (10) to improve the display contrast. The bus electrodes (12a, 14a) may be formed as a multi-layer structure. In this case, for example, the lower-layer bus electrodes are formed with a black metal material and the upper-layer bus electrodes are formed with a light-reflecting material layer, which improves light utilization efficiency and further improves the contrast.
