Abstract: A plasma display device is provided with a plasma display panel and a luminance controller. The luminance controller lowers a luminance on the plasma display panel when there is no change in an input signal for a predetermined position in the plasma display panel within a predetermined time than a luminance when there is a change in the input signal within the predetermined time.

Abstract: A plasma display panel is provided which is capable of suppressing the degradation of the fluorescent material layer by discharge and which ensures a long service life.

Abstract: A plasma display panel has a pair of insulating substrates (a front substrate and a rear substrate) which face each other. A plurality of surface discharge electrodes, each including a transparent scanning electrode and a transparent maintaining electrode arranged with a surface discharge gap in between, are formed in a matrix form on the front substrate. A plurality of scanning trace electrodes, which are made of metal material, are formed extending horizontally on the scanning electrodes. A plurality of first partition walls are formed vertically extending in stripes between the surface discharge electrodes. A plurality of maintaining trace electrodes, connected to the maintaining electrodes, are formed vertically extending on the first partition walls. The front substrate having the electrodes thus formed thereon is covered with a transparent dielectric layer and a magnesia oxide layer in sequence.

Abstract: In a surface discharge type plasma display device, lead-out wirings for a plurality of surface discharge electrode pairs of a scanning electrode 3 and sustaining electrodes 4 are arranged such that current flowing directions of adjacent pairs of the surface discharge electrodes during a sustaining discharge period are opposite to each other.

Abstract: The PDP is divided into a plurality of scan blocks. Immediately before a write discharge period of each scan block, a pre-discharge erasing period or a pre-discharge period and a pre-discharge erasing period is or are established. To minimize the period of time from the pre-discharge to the write discharge, the pre-discharge and the pre-discharge erasing are conducted for each of the scanning and sustaining electrode blocks or in a sequential manner. Furthermore, a first sustaining discharge period of a short time is disposed immediately after the write discharge period for each scan block and a second sustaining discharge period for all display cells is arranged after the write discharge of all scan blocks.

Abstract: Focusing attention on a new fact that a difference in the operating margin between sub-fields becomes remarkable when preliminary discharge is not provided for all sub-fields, but is thinned out, the operating margin for a plasma display panel will be improved by restricting the difference in the operating margin. In the case of the thinned preliminary discharge system, particularly the dependence of maintenance blanking characteristics on the maintenance pulse number becomes remarkable and as a result, the operating margin difference among the sub-fields becomes remarkable, and therefore, parameters for blanking pulse of the sub-field during the maintenance blanking period are set in conformity with the maintenance pulse number (number of times of emission) for each sub-field in order to restrain this operating margin difference.

Abstract: A surface discharge alternating current plasma display panel has a pair of transparent electrodes supplied with current from metal bus electrodes through connecting portions spaced from each other by slits, a dielectric layer covering the pair of transparent electrodes and the metal bus electrodes and a porous insulating layer covering a part of the dielectric layer over the metal bus electrodes; when surface discharge occurs between the transparent electrodes of the pair, the surface discharge is spread toward the bus electrodes; however, the surface discharge can not exceed the slits; for this reason, the surface discharge is concentrated over the transparent electrodes.

Abstract: An electromagnetic field shielding layer made of an electroconductive material and having windows corresponding to display cells is formed on a substrate on the side of display. Color filters are provided on the windows of the electromagnetic field shielding layer to allow the electromagnetic field shielding layer to exist on boundaries between adjacent color filters. The electromagnetic field shielding layer and color filters may be covered with an insulating body layer.
