Abstract:
A flat-panel display device, comprising:a display panel plate;a plurality of display pixels arrayed in a matrix on said display panel plate;a plurality of signal lines formed on said display panel plate along columns of said display pixels;a scanning section formed on said display panel plate, for sequentially and periodically selecting rows of the display pixels to connect the display pixels of a selected row to said signal lines; anda driver section formed on said display panel plate, for driving the display pixels of the selected row via said signal lines;wherein said driver section includes a plurality of signal line driver blocks which are arranged to partition said signal lines into signal line groups, each having a predetermined number of adjacent signal lines, receives individual video signals supplied for said signal line groups from an outside of said display panel plate, and performs operations of driving the signal line groups on the basis of the individual video signals, in parallel;each of said signal line driver blocks includes a sampling section for sampling a corresponding video signal to be supplied to said predetermined number of signal lines, and a timing control circuit for controlling an operation timing of said sampling section according to a common control signal supplied from outside of said display panel plate; andsaid sampling section includes a plurality of transmission lines for transmitting a plurality of component video signals derived from the video signal, and a plurality of analog switches connected via connection wirings to said timing control circuit, respectively assigned to said predetermined number of adjacent signal lines and sequentially assigned to said plurality of transmission lines, each for sampling the component video signal on a corresponding transmission line to be supplied to a corresponding signal line;said plurality of transmission lines of each sampling section extend across the connection wirings in a corresponding signal line driver block and are separated from those included in the other signal line driver blocks, on said display panel plate.
