Abstract: A display panel includes an edge area having a rounded shape and a flat inner area in which a plurality of touch electrodes are disposed. A plurality of driving lines applying a touch driving signal to the plurality of touch electrodes are disposed in the display panel. A touch circuit outputs the touch driving signal applied to the edge area at a voltage level higher than a voltage level of the touch driving signal applied to the inner area.

Abstract: A display apparatus with a touch function and an operating method thereof are provided. The display apparatus with a touch function according to an embodiment of the present disclosure may include a touch line connected to a touch electrode disposed in a display area of the display apparatus, a noise sensing line disposed to be spaced apart from the touch line by a first distance in a non-display area of the display apparatus, a driving signal line for providing a driving signal of the display apparatus in the non-display area, and a touch driving circuit for identifying information on a touch input using a touch input signal acquired through the touch line and a noise signal acquired through the noise sensing line. Accordingly, the information on the touch input can be more accurately identified by controlling a touch input signal using a line for detecting a noise.
