Abstract

Disclosed is a display device including a data driving circuit and a display panel. In the data driving circuit, the plurality of latches store pieces of latch data, respectively, and the plurality of comparison circuit are positioned to correspond to the plurality of latches. Each of the plurality of comparison circuit compares present latch data with previous latch data, and outputs a first bias current control signal depending on the comparison result. The plurality of level shifting circuits respectively output pieces of image data by shifting levels of the pieces of latch data. Each of the plurality of sub-level shifting circuits outputs a second bias current control signal by shifting a level of the first bias current control signal.
