A plasma display panel is provided in which color temperature of the displayed color can be optimized while securing the gradation reproducibility and the stability of driving. The plasma display panel includes a screen in which a plurality of cells arranged in rows and columns emits light by electric discharge between a pair of main electrodes, and each pixel of matrix display has first, second and third cells having different light colors. At least one of the effective area of the main electrode, the thickness of the dielectric layer, the relative dielectric constant of the dielectric material, and the area of the light shield for the first cell is different from that of the second cell.

A plasma display panel is provided that can prevent interference of discharge between rows securely without reducing operation margin. Plural partitions being at a distance from each other define a discharge space of each column in the screen. The column space defined by the partitions is narrowed periodically along the column direction. A surface discharge gap is formed at each enlarging portion of the column space. A pair of plural main electrodes is provided for surface discharge. Each of the main electrodes includes a belt-like bus portion extending in the row direction of the screen and plural gap forming portions protruding in the column direction from the bus portion toward the enlarging portion in each column space.

A method for driving an AC type plasma display panel includes the steps of performing initialization at least once for each frame so as to clear binary setting of wall charge quantity in a screen by discharge except for micro discharge in which electrodes covered with a plurality of fluorescent materials become cathodes, and performing special initialization at frequency of once for M frames, where M=two or more, so as to erase unnecessary wall charge in the screen by discharge in which electrodes become cathodes and that is stronger than the discharge in the initialization.

A display device (1) including a surface discharge type plasma display panel (2) performs an addressing operation, a sustain operation and a reset operation. In the addressing operation, address discharge of an opposed discharge form with the second electrode (Y) used as a cathode is generated between the second electrode (Y) and a third electrode (A) in a cell to be energized or in a cell not to be energized. In the reset operation, an obtuse wave pulse (Pr1) having a negative polarity is applied to the second electrode (Y) so as to generate charge adjustment discharge starting from discharge of the opposed discharge form with the second electrode (Y) used as a cathode between the second electrode (Y) and the third electrode (A).

A plasma display panel includes a pair of substrates forming a discharge space between the substrates, and lateral barrier ribs extending in a row direction and longitudinal barrier ribs extending in a column direction that divide the discharge space into cells. Each lateral barrier rib is divided into two portions in the column direction such that a vent passage is formed in the divided portion. In the plasma display panel, raised portions, which are lower than the lateral barrier ribs and connect the lateral barrier ribs divided into the two portions with each other, are formed in the vent passage.

摘要:
A plasma display device performing display control by utilizing plasma discharge includes a panel having a plurality of address electrodes and a plurality of display electrodes disposed to intersect with the address electrodes, and a drive circuit performing address discharge drive for selectively producing a discharge in cells between the address electrodes and the display electrodes, and display discharge drive for applying to the display electrode a display drive pulse having a voltage increasing with such a gradient as to continuously produce a discharge current in the selected cell. In the display discharge drive performed after the address discharge drive, a display drive pulse with an increasing voltage of gentle gradient is applied to the display electrode, thereby producing faint discharges continuously in the selected cell during the increase of the voltage applied to the display electrode. Display luminance is controlled by the above ramp-wave discharge. In such the ramp-wave discharge, differently from the conventional strong discharge, faint discharges are produced a plurality of times while the display drive pulse is being applied, enabling improvement on the discharge efficiency, and reduction of power consumption.
