Abstract:
A surface-discharge type display device is provided that can reduce power consumption during sustain discharge and suppress the occurrence of illumination failures. A display electrode and a display scan electrode are aligned on a substrate, and a dielectric layer is formed on the substrate so as to cover the display electrode and the display scan electrode. An area having a lower relative permittivity than the dielectric layer is formed in an area surrounded on three sides by the display electrode, the display scan electrode, and the substrate. The dielectric layer allows sufficient wall charges for surface discharge to be accumulated, whereas the lower relative permittivity area allows the capacitance between the display electrode and the display scan electrode to be decreased. Accordingly, the power consumption during sustain discharge is reduced without causing illumination failures.
Abstract:
A mesh barrier rib structure to separate display cells is provided, and each of the display cells is completely separated from the adjacent cells. Bus electrodes are provided to overlap transparent electrodes. The bus electrodes are for example made of a layered body including a white Ag thin film and a black RuO2 thin film. The transparent electrode and the bus electrode form a scan electrode, while the transparent electrode and the bus electrode form a common electrode. The bus electrodes are provided in the closest positions to the surface discharge gap between the transparent electrodes. Therefore, priming discharge is generated in the vicinity of the discharge gap, and light emission can be restrained in the priming period.

The present invention relates to a plasma display panel to improve its light emission efficiency and lower its driving voltage. The plasma display panel of the present invention has electrodes formed on a front substrate. The electrodes of the plasma display panel include first electrodes for receiving scan pulses, second electrodes for receiving first sustain pulses and third electrodes for receiving second sustain pulses. The first dielectric sub-layer formed on a backside of the first electrodes is formed thinner than the second dielectric sub-layer formed on backsides of the second electrodes and the third electrodes.
Abstract:
The invention relates to an AC plasma display panel (12) of the surface discharge type, and more specifically to the structure of the address electrodes (5) of said panel, and to a method of driving said panel. According to the invention, only one address electrode (5) is used for one out of every two columns. Scan (8) and common (7) electrodes may comprise transparent parts (11). These parts (11) may extend over one out every two cells, in a checkerboard fashion. In a preferred embodiment as shown in FIG. 7, the columns may have alternating wide (15) and narrow (16) cells (2). In the driving method according to the invention, all rows are addressed during an addressing phase, and subsequently all rows are simultaneously sustained during a sustain phase.
Abstract:
A plasma display panel is provided in which a reliability of addressing is ensured, a flicker is reduced and the area that a cross talk can spread in the column direction is decreased so that a fluctuation of the display can be reduced. The plasma display panel has a first display electrode and a second display electrode that make an electrode pair for surface discharge. The first and the second display electrodes share one electrode for display of neighboring two rows. A partition is provided that divides a discharge gas space in the column direction only in the area where the first display electrode that is not used as a scanning electrode is positioned.

The partition walls divide a space between the front plate and the back plate into a plurality of display cells. Each of the partition walls is formed by a sheet-like metal plate having an insulated exterior surface, or by laminating a plurality of sheet-like metal plates each having an insulated exterior surface. At least one sheet-like metal plate of each of the partition walls is connected to the drive circuit.
Abstract:
Described herein is an AC plasma display panel in which a discharge part is separated from a bus electrode and a partition wall. In this AC plasma display panel, a high emission efficiency can be obtained. Also described is another AC plasma display panel in which a data electrode having a large width part around the surface discharging gap and a narrow width part. The data electrode may further include a medium width part. In this AC plasma display panel, since counter discharge always occurs near a discharge gap of a scanning electrode by employing the data electrode having a specified shape, a high resolution panel with full-color display can be realized.
