Data driving circuit and display device

Abstract

A data driver circuit and a display device are discussed, which are capable of reducing peak current and improving ground bouncing by optimizing a spread time of a MUX stage based on the counted bit toggle value of the image data. The display device can include a display panel in which a plurality of gate lines, a plurality of data lines, a plurality of sub-pixels, and a demultiplexer are disposed; a data driver circuit that supplies a data voltage corresponding to image data to a plurality of data channels; and a controller that controls the data driver circuit and supplies the image data to the data driver circuit. The demultiplexer includes a plurality of MUX stages and controls connection between the plurality of data channels and the plurality of data lines through switching operations of the plurality of MUX stages.
