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： 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： 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： A display panel driving method capable of realizing a high definition gradation display while reducing power consumption. In each of a plurality of divisional display periods constituting a unit display period in a video signal, a pixel data writing stage is performed for setting each of pixel cells to either a light emitting cell or a non-light emitting cell in accordance with pixel data corresponding to the video signal, and a light emission sustain stage is performed for causing only the light emitting cells to emit light a number of light emissions allocated in correspondence to a weighting factor applied to each of the divisional display periods. A luminance distribution of the video signal is measured every display line on the display panel, and the number of divisional display periods in the unit display period is changed every display line in accordance with the luminance distribution.

摘要： A display panel driving method sequentially writes pixel data of every display line into pixel cells on display lines belonging to a region other than a black display region on a screen, while the method stops writing pixel data into pixel cells on display lines belonging to the black display region or simultaneously sets the pixel cells into a non-light emitting cell state. Since a time spent for each pixel data writing process in one field is reduced, a light emission period (number of times) allocated to each light emission sustain process is increased, or the number of subfields is increased by the reduction in time, thereby making it possible to improve the quality of a displayed image.
