A display device may include a display panel including pixels and at least one common electrode overlapping a portion of the pixels in an active area of the display panel; a gate driver configured to supply a gate signal to the pixels; a source driving integrated circuit configured to supply a data signal to the pixels and configured to supply a common voltage to the common electrode; and a noise compensator circuit configured to receive a plurality of sensing signals from a plurality of sensing lines that are connected to at least one of the display panel, the gate driver, or the source driving integrated circuit, generate a plurality of inverted sensing signals by applying different gain values to signals obtained by inverting phases of each of the plurality of sensing signals, and generate a noise compensation signal based on at least one of the plurality of inverted sensing signals.

Display device

A display device includes a display part including a display panel in which a plurality of pixels is defined, a roller fastened with the display part and configured to wind or unwind the display part, a roller support unit configured to support the roller at both sides of the roller, and a first grounding unit including a body accommodated inside the roller so as to be movable and a contact portion connected to an outer surface of the body and brought into contact with the roller support unit as the body moves, thus maintaining and enhancing continuity of grounding and maximizing the effect of improving EMI.
