1. A display device, comprising:
pixels;
a data driver configured to start outputting data voltages to at least some of the pixels at a first time during a horizontal period, and end outputting the data voltages at a second time during the horizontal period;
sensors; and
a sensor driver configured to change a logic level of a sensing signal of at least some of the sensors at a third time different from the first time and the second time during the horizontal period,
wherein at least one of the first time, the second time, and the third time is changed according to a number of times a logic level of a vertical synchronization signal is changed while a logic level of a horizontal synchronization signal is maintained.
