1. An image display apparatus comprising:
a panel including a plurality of light emitting diodes configured for displaying and for sensing a pointer light; and
a driving controller configured to output a scan signal to a light emitting diode of the plurality of light emitting diodes for each of a plurality of subframe periods,
wherein the driving controller is configured to:
output a scan signal and a data signal to the light emitting diode during the plurality of subframe periods in a first mode corresponding to a display mode,
output only one of the scan signal or the data signal during some subframe periods among the plurality of subframe periods for sensing a pointer light and output the scan signal and the data signal during some other subframe periods among the plurality of subframe periods for displaying, in a second mode,
output only one of the scan signal or the data signal to the light emitting diode during the plurality of subframe periods for sensing a pointer light in a third mode corresponding to a power saving mode or a stand-by mode.
