Abstract
In case that a terminal gradation signal output terminal in a pre-stage display driver and an initial gradation signal output terminal in a next-stage display driver of a plurality of display drivers which are arranged in parallel are used in driving the same gradation signal electrode of a display panel, an output of dummy data from the other gradation signal output terminal which mutually competes with an output timing of a gradation signal from one gradation signal output terminal between both the gradation signal output terminals is suppressed by high impedance control of a corresponding gradation signal output terminal.
