Picture control device and flat-panel display device having the picture control device

A picture control device for a flat-panel display having a plurality of horizontal pixel lines each formed of display pixels arranged in one line, comprising:

• a plurality of driving sections arranged along one side edge of said flat-panel display substantially parallel to said horizontal pixel lines to divide said display pixels into groups, for driving the groups of display pixels, respectively;
• and
• a control section for controlling said driving sections to output pixel data assigned to the respective display pixels during a scanning period for each horizontal pixel line and to drive said display pixels according to the pixel data,
• wherein said plurality of driving sections are arranged for sequentially selecting display pixels for one group under a control of a selection control signal to drive the respective groups of display pixels according to pixel data assigned thereto, said control section includes a plurality of selection control wiring members assigned to said driving sections and electrically separated from each other and distributing means disposed at a position corresponding to a center of said one side edge and connected to said driving sections by two sets of the selection control wiring members such that respective selection control wiring members of each of the two sets are of approximate equal lengths so as to uniformly reduce parasitic capacitance thereof and power consumption of the control section, for distributing the selection control signal to the driving sections.

A flat-panel display device comprising:

• a flat-panel display which has a plurality of horizontal pixel lines each formed of display pixels arranged in one line;
• and
• a picture control device for said flat-panel display, said picture control device including:
• a plurality of driving sections arranged along one side edge of said flat-panel display substantially parallel to said horizontal pixel lines to divide said display pixels into groups, for driving the groups of display pixels, respectively;
• and
• a control section for controlling said driving sections to output pixel data assigned to the respective display pixels during a scanning period for each horizontal pixel line and to drive said display pixels according to the pixel data,
• wherein said control section includes a plurality of data wiring members assigned to said driving sections and electrically separated from each other and distributing means disposed at a position corresponding to a center of said one side edge and connected to said driving sections by two sets of data wiring members such that respective data wiring members of each of the two sets are of approximate equal lengths so as to uniformly reduce parasitic capacitance thereof and power consumption of the control section, for distributing pixel data assigned to said display pixels of each group to a corresponding data wiring member.
