摘要： A plasma display device has a plasma display panel (PDP) and a driver unit driving the PDP. One field for displaying one screen of the PDP is made up of a plurality of subfields having a reset period and an address period. At least one of the plurality of subfields is a subfield for low luminance with number of times of sustain discharge being set to 0 (zero) and a voltage between a scan electrode and a sustain electrode during the address period being set smaller than a firing voltage between the scan electrode and the sustain electrode. The driver unit applies between the scan electrodes and the sustain electrodes a voltage smaller than the firing voltage between the scan electrodes and the sustain electrodes in a reset period of a subfield subsequent to the subfield for low luminance. As a result, luminance when reproducing black can be lowered.

摘要： A plasma display device includes a plasma display panel and a driver unit driving the plasma display panel. The plasma display panel includes a first plate on which a sustain electrode and a scan electrode, a dielectric layer, an address electrode extending in a direction intersecting with the sustain electrode, and a protective layer are sequentially stacked and a second plate disposed to face the first plate via a discharge space. On the second plate, a barrier rib extending in the direction intersecting with the sustain electrode is formed. One edge part of the address electrode lies on the barrier rib and the other edge part of the address electrode lies on the discharge space. During an address period, the driver unit applies a scan pulse operating as an anode to the scan electrode and applies an address pulse operating as a cathode to the address electrode. This makes it possible to prevent erroneous discharge.

摘要： An optical filter is provided on the output side of light from plural kinds of cells that output light with colors different from one another. In the optical filter, the penetrable rate of at least a portion of the wavelength band of light output from the cell with the color having highest luminescent intensity is set lower than that of the wavelength band of other kinds of cells. Consequently, the reflectance rate of outer light incident to a display can be reduced. Particularly, in a room environment using artificial lighting, the reflectance rate of outer light can be reduced in the wavelength band of light with relatively high luminescent intensity. Resultingly, bright room contrast can be improved by suppressing the reflection of outer light. Since the penetrable rate of the color with the highest luminescent intensity is reduced, reduction in brightness of the display can be kept to a minimum.

摘要： In a long-gap discharge using a trigger discharge in a display cell of a PDP having three electrodes (X, Y, A), a technology capable of stably generating the trigger discharge with low power consumption by using a float electrode is provided. In a dielectric layer of the PDP, a long gap is formed between first and second display electrodes, first and second float electrodes which are capacitive-coupled to the first and second display electrodes are formed, and a short gap is formed between the first and second float electrodes. A sustain pulse is applied to the first and second display electrodes, thereby generating a small trigger discharge in the short gap. Subsequently to this discharge, a main discharge at the long gap is generated. Electrodes and capacitances are structured so that the main discharge has an intensity equal to or smaller than one-fifth of an intensity of the trigger discharge.
