Abstract: A display device may include a first touch sensing member on a top surface of a display panel, a second touch sensing member on a bottom surface of the display panel, a main FPCB coupled to the display panel and including first and second connecting portions, a first touch FPCB connected to the first touch sensing member and the first connecting portion, a second touch FPCB connected to the second touch sensing member and the second connecting portion, a first touch driving circuit on the first touch FPCB, and a second touch driving circuit on the second touch FPCB. The first touch driving circuit and the first connecting portion may be positioned opposite to each other with respect to the main FPCB. The second touch driving circuit and the second connecting portion may be positioned opposite to each other with respect to the main FPCB.

Abstract: A method of driving a display panel is provided. The method includes generating first compensated and second compensated data based on input image data, outputting the first compensated data to a data driver during a first frame, outputting the first smoothing data to the data driver during a second frame subsequent to the first frame, and outputting the second compensated data to the data driver during an n-th frame subsequent to the second frame (where n is a natural number greater than two). The first smoothing data has a value between a value of the first compensated data and a value of the second compensated data.
