摘要： A driver device for a display panel. Pixel cells are arranged on respective display lines of the display panel. Each N adjacent display lines makes one display line group. N is an integer of two or more. The pixels in each display line group are driven to emit light at different luminance levels based on one of M different dither patterns. One of the M dither patterns is selected sequentially and in predetermined periods, and the selected dither pattern is used. M is less than N. In the dither processing, N different weighting values are allocated to the N display lines in the display line group, respectively.

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.

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.
