Abstract
A picture control device is used for driving a flat-panel display having a plurality of horizontal pixel lines each formed of display pixels arranged in one line, and composed of first and second driver groups which are arranged to divide the display pixels into groups and drive the groups of display pixels, respectively, and a drive circuit board for controlling the driver groups to output pixel data assigned to the respective display pixels during a scanning period for each horizontal pixel line and to drive the display pixels according to the pixel data. In particular, the drive circuit board includes a gate-array control section connected to the first and second driver groups by first and second wiring lines electrically separated from each other, for distributing pixel data assigned to the display pixels of each group to a corresponding driving group via a corresponding wiring line.
