Abstract
A display device includes a display panel including pixels, an active area on which an image is configured to be displayed, and a black matrix area on which an image is not configured to be displayed, touch sensor electrodes configured to detect a touch of an external object, the touch sensor electrodes disposed in the active area, and detection input electrodes configured to generate mutual capacitance with the touch sensor electrodes, the detection input electrodes disposed in an edge area of the display panel that overlaps the black matrix area.

17. A method of detecting a touch in a display device, the method comprising:
-
obtaining a first detection output signal generated by a self-capacitance type from touch sensor electrodes; obtaining a second detection output signal generated by a mutual-capacitance type from the touch sensor electrodes; and extracting touch coordinates by combining the first detection output signal and the second detection output signal, wherein the extracting of the touch coordinates comprises; calculating an average value of a value of the first detection output signal and a value of the second detection output signal; combining the first and second detection output signals for each position of the touch sensor electrodes; and extracting the touch coordinates by performing interpolation on the combined signal based on the average value.
