摘要： 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.
