Abstract:
PURPOSE: A display panel is provided to simplify and slim the structure and to reduce the producing cost by reducing the number of electric devices for driving at the same time. CONSTITUTION: A discharging space of a display cell is formed by covering a pair of common electrodes (5,6) and a pair of separated electrode flaps(7,8) arranged on a front glass substrate with a dielectric layer and by engraving a concave part in a corresponding part of a rear glass substrate. Many display cells are arranged and layers of fluorescent substance of red, green and blue as three primary colors are sequentially spread on the bottom of each concave part. When a certain voltage is fed between the pair of common electrodes and the pair of separated electrode flaps, far infrared rays are absorbed in the layer of fluorescent substance and a certain fluorescent color is emitted to the outside through the front glass substrate by generating a plasma in the discharging space inside the concave part.
Abstract:
An LER LUWPL source luminaire (1) having a magnetron (2) heat conductingly mounted below a finned heat dissipater (3) with a suspension eye (4). The magnetron is attached to a microwave transition (5) and a lucent crucible (6). An imperforate cover (8) extends down from the heat dissipater and is closed by a transparent screen (9), held to the cover by a moulding (10). The moulding supports a polished-sheet-metal reflector (11) extending back to the lucent crucible, with its reflective surfaces obliquely facing both the crucible and the screen for reflection of light from the crucible out of the luminaire via the screen. The moulding (10) is generally square shaped and the reflector comprises four triangular faces (12), pyramidally arranged, with a square base embodied by a rim (14) supported on the top of the screen (9) above the moulding (10). The faces converge to a virtual apex (15), on the central axis (16) of the lucent crucible. This axis is coincident with the pyramid's normal axis (17) from the apex to the centre of the base. The faces (12) are angled at 45° to the base. The apex is virtual in that the crucible and its backing piece (18) project through an aperture 19 in the reflector, above which the apex would exist if the aperture were not there
Abstract:
The invention concerns a display panel comprising a front faceplate (1) and a rear faceplate (4) providing between them a two-dimensional matrix of zones filled with discharge gas, addressing means (X, Y) for selectively activating pre-selected discharge zones by depositing therein electric charges, and a device for generating microwave electromagnetic radiation (7) adapted to apply through the rear faceplate (4) to the assembly of the display panel discharge zones, a microwave radiation of sufficient intensity to generate plasma discharges solely in the activated discharge zones. Thus, an easy-to-monitor panel with high luminous efficacy is obtained wherein the addressing and maintenance functions are separate.
Abstract:
The present invention is concerned with a display panel having display cells, each of which is discharged to glow by means of paired cell-by-cell common electrodes and a discrete electrode, set in array, and a driving method for the display panel. An object of the present invention is to decrease the number of discrete contacts linked to the discrete electrodes so that the display cells can be driven discretely. Another object thereof is to define time domains, during which a plurality of common electrodes is controlled, within the period of a unit sequence so that the display cells can be driven discretely. A display panel has common electrodes, a plurality of cell-by-cell common electrodes, and discrete electrodes. The common electrodes are extending in columns on a transparent substrate. The cell-by-cell common electrodes are extending in rows from the common electrodes. The discrete electrodes are located among the adjoining cell-by-cell common electrodes on the transparent substrate. Display cells each of which is discharged to glow by means of paired cell-by-cell common electrodes and a discrete electrode are arranged in the display panel. According to a driving method for the display panel, the cell-by-cell common electrodes are interposed between the plurality of adjoining common electrodes. The discrete electrodes are located successively over display cells adjoining in rows. Time domains are determined during which display pulses are applied sequentially to the plurality of common electrodes. A unit sequence is completed over the time domains. Discharge control pulses are applied to the discrete electrodes. Thus, the display cells are lit or unlit.

According to the present invention with the above arrangement, the electrode structure can be simplified to reduce manufacturing steps in number, driving using a pulse memory scheme which can be conventionally realized by only a DC type plasma display discharge tube having high emission efficiency and excellent responsibility is made possible, and a plasma display discharge tube having a long-life AC type electrode can be obtained.
