Disclosed is a flat type fluorescent lamp having a discharge space divided into a plurality of discharge areas. The flat type fluorescent lamp includes a first substrate, a second substrate separated from the first substrate in a predetermined distance to provide a discharge space containing a discharge material, first and second electrodes for applying a voltage to the discharge space and being disposed on the second substrate, and a sealing member for sealing side portions of the first and second substrates to isolate the discharge space from a peripheral space thereof. A plurality of barrier ribs having a slender shape are disposed in the discharge space and perpendicular to the first and second electrodes to divide the discharge space into a plurality of discharge areas. Accordingly, plasma converted from the discharge material has a uniform density through out the discharge space, thereby increasing brightness and uniformity of a light to be supplied to a display panel.

A sealing electrode for discharge lamp having electrically conductive cup, and an emitter pellet is disclosed. The cup seals a passage into the discharge lamp, and additionally supports the electrode pellet or tip for the discharge. The design enables the emitter, electrode and seal structure to be made separately off line, while also enabling the emitter to be protected from contaminants during subsequent assembly.

Abstract:
The invention relates to an improved method of production for a flat radiator discharge lamp designed for dielectrically impeded discharges, in which, during a filling step for the discharge vessel, a plate of the discharge vessel is jacked up on parts, later softening, of support elements in order to be lowered onto the other plate at a specific temperature. In this case, the support elements serve, in addition, to improve the mechanical stability of the finished flat radiator. According to the invention, only a small number of the support elements present in a relatively large number are used for the outlined function of holding up the plate.

The disclosed DC type plasma display for back light comprises a rear substrate functioning as a cathode electrode; an anode electrode plate arranged over the rear substrate with a predetermined distance and having a plurality of holes therein; a seal frame sealing the rear substrate and the anode electrode plate by inserting between the rear substrate and the anode electrode plate; a front substrate arranged over the anode electrode plate with a predetermined distance and having a fluorescent layer formed on the down side thereof; a plurality of spacers interposed between the anode electrode plate and the front substrate; a seal paste sealing the edges of the anode electrode plate and the front substrate; and a discharge gas filled in the space between the rear substrate and the front substrate.
Abstract:
A planar fluorescent lamp equipped with a pair of flat electrodes and a method for fabricating such lamp are disclosed. In the planar fluorescent lamp, a lamp housing and a cover plate which are both formed of a soda-lime glass can be bonded together to form a vacuum tight seal by glass frit. A pair of flat electrodes and a pair of getter strips are pre-mounted in the cavity of the planar lamp. The pair of flat electrodes run substantially the full width of the interior cavity of the lamp such that a substantially uniform electric discharge field can be formed in the cavity when a RF power is supplied to the electrodes. A bottom panel of the lamp housing may be fabricated in a ribbed structure to improve the rigidity of the bottom panel such that it does not bow in when the cavity is sealed under a vacuum pressure.
Abstract:
An energy-saving, high-outputting and high-efficiency, electric discharging type of illumination apparatus and associated units are provided. nullNnull thin divisional electrode pieces are arranged at relatively narrow intervals nullanull on the electrode-application area 1, which is defined on the bottom of a flat container, and the divisional electrode pieces are fixed to the electrode-application area 1 with an intervening sheet of good electrically insulating and thermally conductive material laid therebetween. A front glass 4 having fluorescence coating on its inside is placed to confront the electrode-application area 1. The electrode-application area 1 is close to a double-walled structure nullcnull, in which cooling water nulldnull is circulated for cooling the divisional electrode pieces 2. On the outside of the double-walled structure nullcnull, nullnnull1null rod magnets 5 are arranged to be in alignment with the electrode-to-electrode space nullanull, alternating N pole and S pole. nullNnull power supplies 10 of low frequency are connected to the nullnnull divisional electrodes 2 so that these divisional electrodes may be supplied with voltages of the same amplitude, each shifted 1/n period out of phase. The nullnnull power supplies 10 are connected in the form of star, and are connected to a controller 11 for controlling the frequency, amplitude and phase (including wave shape) of the voltage wave. The power supply uses an insulation transformer to float the voltages appearing at the output terminals. Thus, an electric discharge appears exclusively among divisional electrodes 2.
