Abstract:
A gas discharge panel includes several pairs of column (X) electrodes arranged on a first substrate and several pairs of row (Y) electrodes arranged on a second substrate, the column and row electrodes being orthogonally oriented and in spaced, opposed relation to define therebetween a gap filled with an ionizable gas. In a first driving configuration, a corresponding electrode of each pair of (X) electrodes is selectively driven by an (X) address driver and similarly a corresponding one of each of the (Y) electrode pairs is selectively driven by a (Y) address driver. The other electrode of each of the (X) and (Y) electrode pairs then is connected in common to respective (X) and (Y) sustain voltage driver terminals. In a further embodiment, each of the (X) and (Y) electrode pairs is arranged in corresponding groups of electrode pairs, each group including a common number of such pairs. First electrodes of each pair of each group are connected to a common output terminal of an address and sustain voltage driver; thus, plural address and sustain voltage driver outputs corresponding to the plural groups are employed for each of the (X) and (Y) electrode pairs. The second electrodes of corresponding pairs of the plural groups are connected to respectively corresponding, further common output terminals of address and sustain voltage drivers; thus, a plurality of further common terminals corresponding to the number of electrode pairs in each group are provided, as to each of the (X) and (Y) electrodes. The panel as thus configured affords decoding of addressing signals applied to the common terminals by means of plasma coupling within the panel whereby the discharge point or cell defined by a desired electrode of each of the column and the row electrode pairs can be addressed selectively. A further embodiment provides shifting of the display to successive positions in either the (X) or (Y) directions.
Abstract:
A gas discharge display device includes a center plate which comprises cells for defining a display area. The center plate, which is sandwiched between two electrode holding plates each of which has an electrode coated with a dielectric layer, is in the form of a porous insulating layer having a low dielectric constant.
Abstract:
A plasma display panel is provided with front and rear boards each having a plurality of electrode members, respectively. The front and rear boards are spaced apart to define a discharge space filled with an ionizable gas. The front board is equipped with a front glass plate including a fluorescent or phosphorescent element set on its inside surface, and a central plate having a number of holes therethrough. The electrode members of the front board are affixed by a coating to an inside surface of the central plate. The fluorescent or phosphorescent elements are placed at the rear of the electrode members on the central plate.
Abstract:
A gas discharge panel which has a shift layer for shifting a priming fire with a surface discharge and a display layer for memory and display when a discharge is produced between opposing electrodes. An equivalent electrostatic capacitance provided by a dielectric layer coated on the shift layer is made larger than that by a dielectric layer on the display layer to increase thereby a wall charge on the shift layer resulting from the surface discharge and decrease that resulting from the discharge between the opposing electrodes, thereby eliminating the possibility that an unnecessary priming fire for shifting is generated at the position of the discharge produced between the opposing electrodes.
Abstract:
An addressable gaseous discharge device utilized for information display comprises a pair of spaced parallel oppositely positioned insulating walls forming between them a gas cell filled with ionizable gas. At least one of the insulating walls is transparent. The perimeters of the insulating walls are hermetically sealed. Field electrodes mounted on the insulating walls apply a microwave electric field to the gas cell and field electrodes mounted on the insulating walls partly and selectively apply a magnetic field in a direction crossing the microwave electric field. A glow discharge occurs in a selected part of the gas cell when the two applied fields meet the condition of cyclotron resonance of an electron.
Abstract:
The invention relates to a composite sheet which is used to protect displays, especially plasma displays. The composite sheet is essentially comprised of three sheets. The inner sheet (1) is made of a thermoplastic synthetic material and the outer sheets (2,3) are made of glass. The individual sheets (1,2,3) are firmly joined to each other by means of a thermoplastic polyurethane film (4). The glass sheet (3) facing the display is provided with electric screening. The inventive sheet, when detached from the display, can be used in a plurality of ways owing to the construction thereof. It is light, shatterproof and offers a wide range of design opportunities.
Abstract:
The invention concerns a method for making a plasma display panel faceplate, comprising the deposit of electrodes from a paste containing a metal powder and a mineral binder, and firing the deposit. The invention is characterised in that the mineral binder composition and the conditions of firing are adapted so that, after the deposit has been fired, the binder is recrystallized. The crystallized state of the binder enables to eliminate yellowing problems which occur during subsequent heat treatments.
