Classification: CPC G | IPC G

Claim 0:
1. 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 by being commonly operated as reception electrodes for receiving a down-link signal from an input device, or by being commonly operated as transmission electrodes for transmitting an up-link signal to the input device,

wherein the sensor controller is configured to operate the first electrode and the second electrode in the first mode during at least a first period of each of the first driving mode and the second driving mode,
wherein the sensor controller is configured to operate the first electrode and the second electrode in the second mode during at least a second period of each of the first driving mode and the second driving mode, and
wherein the input sensor is configured to change from the first driving mode to the second driving mode when the input sensor senses a touch input of the input device or a hovering event of the input device in the second mode of the first driving mode.
