1. A display device comprising:
display pixels in a display area of a display panel;
light-sensing pixels alternately arranged with the display pixels in the display area and configured to sense light reflected from an object above the display pixels;
a display scan driver configured to sequentially provide display scan signals to the display pixels through display scan lines;
a flicker detection circuit configured to detect an occurrence of flicker in the display area by using light-sensing signals received from the light-sensing pixels;
a touch sensing circuit configured to detect a touch from a user and coordinate data of a location of the touch via touch electrodes of a touch sensor; and
a main driving circuit configured to maintain or change a driving mode of the touch sensor in units of at least one frame based on a flicker detection result and a flicker degree analysis result from the flicker detection circuit.
