Claim 14:
15. A display device, comprising:
a display panel configured to generate an image; and
an input sensor configured to operate in a first driving mode or a second driving mode,
wherein the input sensor comprises:
a sensor layer including a first electrode and a second electrode crossing each other; and
a sensor controller configured to operate in a first mode, in which the first electrode and the second electrode are operated as different groups, or in a second mode, in which the first electrode and the second electrode are operated as a same group,

wherein the sensor controller is configured to have an operation time of the first mode, which is longer than an operation time of the second mode, in response to the input sensor operating in the first driving mode during successive sensing periods of a first group,
wherein the sensor controller is configured to have the operation time of the second mode, which is longer than the operation time of the first mode, in response to the input sensor operating in the second driving mode during successive sensing periods of a second group,
wherein each of the successive sensing periods of the first group comprises a plurality of first mode periods, in which the sensor controller is operated in the first mode,
wherein, during the successive sensing periods of the first group, an operation of the input sensor is repeated by units of i sensing periods, where i is a natural number that is equal to or larger than 2,
wherein at least one sensing period of the i sensing periods comprises a second mode period, in which the sensor controller is operated in the second mode,
wherein each of remaining sensing periods of the i sensing periods comprise the first mode periods, a number of which is m that is a natural number equal to or greater than 2, and
wherein the at least one sensing period further comprises the first mode periods, a number of which is less than m.
