摘要： A plasma display panel capable of improving dark contrast. A unit light emission region is comprised of a display discharge cell in which a discharge is produced between portions of row electrodes X, Y of each row electrode pair (X, Y) opposing each other, and a reset and address discharge cell arranged in parallel with the display discharge cell, in which a discharge is produced between portions of the row electrode Y and a row electrode X of another adjacent row electrode pair (X, Y). The display discharge cell and reset and address discharge cell are communicated with each other. A light absorbing layer is formed in a portion of the reset and address discharge cell opposing the display surface. According to another aspect, the unit light emission region in the display panel comprises a first discharge cell and a second discharge cell comprising a light absorbing layer. A sustain discharge for emitting light for displaying an image is produced in the first discharge cell, while a variety of control discharges causing light emission not associated with a displayed image are produced in the second discharge cell. According to a further aspect, unit light emission regions are formed at intersections of each of a plurality of first row electrodes and second row electrodes alternately formed on the front substrate such that the first row electrode and the second electrode in each pair are arranged in a reverse order to the preceding pair, and each of a plurality of column electrodes.

摘要： A display and a driving method of a display panel capable of improving a dark contrast. In driving the display panel having light-emission areas formed at each intersection of a plurality of pairs of row electrodes and a plurality of column electrodes, each of the light-emission areas having a first discharge cell including a portion where the respective row electrodes in pair are opposed to each other with a predetermined discharge gap within a discharge space and a second discharge cell including a portion where a light absorptive layer is provided and one row electrode of the row electrode pair and the other row electrode of the row electrode pair adjacent to this row electrode pair are opposed to each other with a predetermined discharge gap, an address discharge is produced within the second discharge cell, to set the second discharge cell at a light-on state or a light-off state, by applying a pixel data pulse based on an input image signal, to respective column electrodes, while applying a scanning pulse to a row electrode having the longer distance to the first discharge cell, of the respective row electrodes within the second discharge cell. This structure causes the address discharge within the second discharge cell relatively distant from the first discharge cell, so that the amount of a ultraviolet ray by the address discharge flowing into the first discharge cell is reduced, to suppress the deterioration of the dark contrast.

摘要： A display panel includes a plurality of unit light emission areas (light emission elements) arranged in a matrix. Each unit light emission area is defined by a first discharge cell and a second discharge cell. The second discharge cell has a light-absorbing layer. When the display panel is driven to express an image having a plurality of gradation levels, address discharge is selectively caused in the second discharge cells in accordance with an input image signal. Light leaks to the first discharge cell from the second discharge cell upon the address discharge. This light is used to express the gradation of low luminance. Since luminance difference between gradation levels of a low luminance image is reduced, it is possible to display a high quality, low luminance image.

摘要： A driving apparatus of a plasma display panel performs allows image display in a desired way. When discharge cells are driven to repetitively execute a sustain-discharge by the application of sustaining pulses to row electrodes the number of times corresponding to subfields, a ratio of changes of a voltage value in a trailing interval of the last sustaining pulse among those sustaining pulses is set to be milder than that of a voltage value in a trailing interval of the sustaining pulse which is applied just before the last sustaining pulse. Further, description has been made for a driving method of a plasma display panel which can perform an image display of high quality by performing a proper selective discharge while preventing an erroneous discharge of the discharge cells in a pixel data writing step. A trailing edge portion of the sustaining pulse which is applied finally among the sustaining pulses applied in a light emission sustaining step has an undershoot part below a ground potential.

摘要： A plasma display device and a method for driving a Plasma Display Panel (PDP), which can reduce power consumption without causing display malfunction or reducing image quality, are provided. When the input of an image signal is stopped or when an input image signal is in an entirely-black image state, the application of a drive pulse for driving the PDP is stopped. Here, when the input of the image signal is resumed or when the input image signal switches from the entirely-black image state to a normal image state, the absolute value of a peak potential of the drive pulse or the pulse width thereof is increased to increase the strength of discharge until a predetermined period elapses after the resumption or switching and then the absolute value of a peak potential of the drive pulse or the pulse width is returned to a normal absolute value or a normal pulse width.
