Patent ID: 7777713

Claim:
A display device comprising: a display panel including: a plurality of data lines extending in a column direction, a plurality of scan lines extending in a row direction, a plurality of pixels disposed at respective intersections of said plurality of data lines and said plurality of scan lines, and a dummy data line arranged in parallel to said plurality of data lines; a data line driving circuitry driving said plurality of data lines and said dummy data line; and a scan line driving circuitry driving said plurality of scan lines, wherein: said data line driving circuitry feeds a dummy signal to said scan line driving circuitry through said dummy data line, said scan line driving circuitry drives said scan lines in response to said dummy signal, said data line driving circuitry feeds said dummy signal to said scan line driving circuitry through connection nodes located at intersections of said plurality of scan lines and said dummy data line, said scan line driving circuitry includes a plurality of gate driver ICs for driving said plurality of said scan lines, wherein each of said gate driver ICs includes: a comparator receiving said dummy signal and generating a scan control signal from said dummy signal and a reference voltage, and an output circuit unit drives associated ones of said plurality scan lines in response to said scan control signal, wherein a pulse width of said scan control signal generated by said comparator within a first gate driver IC among said plurality of gate driver ICs located relatively away from said data line driving circuitry is larger than a pulse width of said scan control signal generated by said comparator within a second gate driver IC among said plurality of gate driver ICs located relatively close to said data line driving circuitry.
