Classification: CPC G | IPC G

Claim 13:
14. A display apparatus with a touch function comprising:
a drive integrated circuit electrically connected to a driving signal line, the drive integrated circuited configured to generate a driving signal of the display apparatus and provide the driving signal via the driving signal line;
a noise detector configured to identify a noise signal related to the driving signal using a noise sensing line disposed in a non-display area of the display apparatus;
a touch driver configured to identify a touch input signal corresponding to a touch input to the display apparatus, and to identify information on the touch input based on the touch input signal and the noise signal;
a guard line disposed between the noise sensing line included in the noise detector and a touch line included in the touch driver, the guard line configured to block the noise signal;
a ground line spaced apart from the touch line in the non-display area; and
a light emitting diode electrically connected to the drive integrated circuit, the light emitting diode including an anode, a cathode, and a light emitting layer between the anode and the cathode,
wherein the cathode of the light emitting diode extends to overlap the touch line, the guard line, and the noise sensing line from a plan view, and
wherein the noise sensing line is disposed between the guard line and the ground line.
