摘要： A drive method of a plasma display panel that can increase the dark contrast, without causing a discharge failure. When a discharge cell that assumes a black display state in a first field from among first and a second fields that are adjacent in time and switches to a display state representing a brightness other than black in the second field is detected as a lighting transition cell, at least one drive of the below-described first and second forced lighting drives is executed. In the first forced lighting drive, the lighting transition cell is forcibly set into the lighting mode only in the address process of a predetermined subfield within the field in the first field. In the second forced lighting drive, an adjacent discharge cell that is adjacent to the lighting transition cell is forcibly set into the lighting mode only in the address process of the predetermined subfield in the second field.

摘要： A display panel drive suppresses dither patterns in a displayed image. Each of the display lines of the panel is divided into M display line groups including a group of [M≅(k−1)+1]th display lines (where M is a natural number, and k is a natural number of n/M or smaller), a group of [M≅(k−1)+2]th display lines, . . . and a group of [M≅(k−1)+M]th display lines. A different offset value is added to pixel data corresponding to each display line group to derive multi-grayscale pixel data. Then, a lighting or extinction mode setting is done based on the pixel data with respect to each pixel cell belonging to the display line groups, each different in at least M subsubfields among subfields constituting a video signal field. In one example, the luminance levels represented by the pixel cells vertically adjacent to one another in a screen are varied.

摘要： An improved driving device for a display panel. In the display panel, pixel cells serving as pixels are positioned in a plurality of display lines. The driving device drives the display panel according to pixel data derived from an input image signal. The display lines are divided into a plurality of display line groups, and each group includes a plurality of neighboring display lines. The driving device has a light emission driving circuit. This circuit causes the pixel cells in each of the neighboring display lines in the respective display line groups to emit light at different brightness levels based on weighting values assigned to the display lines. The weighting values are assigned to the display lines such that bias in brightness differences between the pixel cells positioned in neighboring display lines falls within a prescribed range for all neighboring display lines in the display panel.

摘要： Prepared is brightness frequency data that indicates the number of pixels, having the same brightnesses in a brightness distribution for each of the fields represented by an input image signal. Based on the brightness frequency data, the number of subfields for emission at each brightness in a brightness region is adjusted for each of at least two brightness regions. As a result, the greater the frequency indicating the total number of pixels at each of the same brightnesses in a brightness region, the larger the number of subfields allocated to that brightness region. Therefore, satisfactory grayscale representation suitable to human visual characteristics is achieved.

摘要： A method of grayscale-driving a display panel in accordance with pixel data derived from a video signal. The display panel includes a plurality of display lines, with a plurality of pixel cells serving as pixels being arranged on each display line. A display period of a single field of the video signal is divided into a plurality of subfields. The method includes dividing one subfield into M lower subfields. M is an integer greater than one. M groups of display lines are prepared by sequentially taking every M display lines from the display lines. First to Mth address steps are performed in the M lower subfields respectively and sequentially. Each address step sets the pixel cells belonging to the display lines of the display line group concerned, to a drive mode determined by the pixel data. A first light emission step is performed to cause the pixel cells whose drive mode is a lit mode, to emit light directly before or after the address step concerned. Another subfield is divided into N lower subfields. N is smaller than M. N groups of L continuos address steps are prepared from the first to Mth address steps. L is an integer greater than one. The N groups of L continuous address steps are performed in the N lower subfields respectively and sequentially. A second light emission step is performed to cause the pixel cells whose drive mode is the lit mode, to emit light directly before or after the address step group concerned.

摘要： A plasma display device which improves the contrast of an image displayed. The plasma display device includes a plurality of row electrodes formed in pairs corresponding to each display line, a plurality of column electrodes arranged to cross the row electrodes to form a discharge cell corresponding to one pixel at each intersection with a pair of said row electrodes, and a driving controller for controlling driving of the row and column electrodes. A gradation display of input pixel data is performed by dividing one field display period into a plurality of subfields. The driving controller, when one field of input pixel data is displayed, changes the number of reset discharges for initializing all discharge cells in accordance with an average luminance value of input pixel data in the preceding field.
