Abstract
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.
