1. A display device comprising:
a display panel;
an input sensor disposed on the display panel, the input sensor including sensing electrodes;
a master readout circuit electrically connected with a first portion of the sensing electrodes among the sensing electrodes and generating first reception signals corresponding to signals received from the first portion of the sensing electrodes; and
a slave readout circuit electrically connected with a second portion of the sensing electrodes among the sensing electrodes and generating second reception signals corresponding to signals received from the second portion of the sensing electrodes,
wherein the master readout circuit provides a synchronization signal to the slave readout circuit, and the slave readout circuit operates in response to the synchronization signal and provides a sensing signal corresponding to the second reception signals to the master readout circuit.
