Abstract: A plasma display having a discharge cell, the emission efficiency of which is improved by generating first and second discharges with one sustaining pulse. A first discharge is generated by increasing a voltage up to a maximal value through a LC resonance formed by a recovery coil and a panel capacitor. A second discharge is generated by connecting the panel capacitor to a power supply when the voltage falls a predetermined amount below the maximal value, thereby increasing the voltage to a predetermined level above the maximal value.

Abstract: A plasma display panel has address properties stabilized. A priming discharge is performed between auxiliary electrodes (17), which are formed on a front substrate (1) and coupled with scan electrodes (6) and priming electrodes (14) formed on a back substrate (2). Furthermore, a material layer (5) containing at least one of alkali metal oxide, alkaline earth metal oxide and fluoride is provided on regions corresponding to priming discharge spaces (30) (gap parts 13) on the back substrate (2). 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: The invention is a plasma display panel capable of stabilizing the addressing characteristics. A barrier rib is formed by longitudinal barrier ribs portion orthogonal to the scan electrodes and sustain electrodes on the front substrate, and side barrier rib portions crossing with these longitudinal barrier rib portions, to form cell spaces and form interstice portions between the cell spaces, and priming electrodes for producing a discharge between the front substrate and the rear substrate within the interstice portions are formed. Stable priming discharge is produced with certainty by the scan electrode and the priming electrode, hence decreasing the discharge time lag at the time of addressing and stabilizing the addressing characteristics.

Abstract: Plasma display panel (PDP), PDP display apparatus, and method for driving the PDP. The PDP is a surface discharge AC PDP having a first substrate and a second substrate arranged to face each other with barrier ribs interposed therebetween. A first electrode and a second electrode are arranged on a facing surface of the first substrate so as to extend parallel to each other, and are covered with a dielectric layer. A third electrode is arranged on a facing surface of the second substrate so as to extend orthogonally to the first and second electrodes. A discharge gas is enclosed within a discharge space defined between the interposed barrier ribs. In the above PDP, the discharge gas is a gas mixture containing xenon. The xenon component comprises at least 5 vol % and less than 100 vol %, and has a partial pressure of at least 2 kPa. Furthermore, the gap between the first and second electrodes in the PDP is greater than a height of the discharge space.

Abstract: Thin diamond films can be selectively deposited imagewise on a substrate by gas phase synthesis. The substrate may be either a silicon substrate or a basal thin diamond film formed beforehand on a substrate by gas phase synthesis. Where a silicon substrate is used, its surface is first abraded to give a surface roughness suitable for gas phase synthesis of diamond. When a basal thin diamond film is used, a coating material capable of withstanding a temperature higher than a substrate temperature required for gas phase synthesis of diamond and having a high etching selectivity to diamond is needed to cover areas other than where the thin diamond film is to be newly formed. When a lift-off method is used, a thin masking film having a melting point higher than a temperature to be employed for gas phase synthesis of diamond can also be used in place of the coating material described above.

A plurality of such diamond thin film thermistors can simultaneously be formed on a single substrate, and the substrate is cut with a dicing saw to provide individual diamond thin film thermistor chips of the same quality.
