Abstract: A touch display device includes a plurality of touch electrodes that are arranged outside or inside a display panel and a touch sensing circuit that outputs a touch driving signal to drive at least one of the plurality of touch electrodes and senses a touch or a touch position, the touch driving signal output in each touch section for the touch mode includes a plurality of waveforms to which a rectangular wave is modulated, and each of the plurality of waveforms includes one or more different amplitudes in a rising section and a falling section. Accordingly, it is possible to prevent electromagnetic interference (EMI).

Abstract: A display device can include a display panel including multiple pixels each of which includes multiple sub-pixels. The display device can further include multiple data lines respectively connected to the multiple sub-pixels, multiple gate lines respectively connected to the multiple pixels, and N multiplexers (MUX) (N is a natural number larger than 1) disposed at input terminals of the multiple data lines. In one horizontal (H) period, a length of a turn-on period of a first MUX can be different from that of a turn-on period of an Nth MUX, where the one H period is a period in which a scan signal is supplied through one gate line.
