An input sensor of a display device includes a plurality of first electrodes, a plurality of second electrodes crossing the plurality of first electrodes, and a sensor driver selectively operating in a first proximity sensing mode and a second proximity sensing mode. The sensor driver outputs a plurality of transmission signals to the plurality of first electrodes and receives sensing signals from the plurality of second electrodes. The plurality of transmission signals includes a signal swinging between a first high level and a first low level during the first proximity sensing mode. The plurality of transmission signals is a signal swinging between a second high level and a second low level during a second proximity sensing mode. The second high level is a voltage level greater than the first high level.

Input sensor, display device and driving method thereof

A touch sensor apparatus may include a multiplexer including a first transistor connected to a first touch sensor and a second transistor connected to a second touch sensor, a touch driver connected to the first touch sensor through the first transistor and connected to the second touch sensor through the second transistor, the first touch sensor disposed at a first distance from the touch driver and the second touch sensor disposed at a second distance shorter than the first distance from the touch driver. A first on-resistance of the first transistor may be smaller than a second on-resistance of the second transistor.

Touch sensor apparatus and display apparatus including the same

A display device includes: a display panel configured to display an image; an input sensor on the display panel and configured to operate in a first sensing mode or a second sensing mode different from the first sensing mode; and a sensor controller configured to drive the input sensor, wherein the sensor controller is configured to drive the input sensor under a first driving condition different from a driving condition of the first sensing mode in response to the second sensing mode being entered, and the sensor controller is configured to change the first driving condition to a second driving condition different from the first driving condition according to a specific event which occurs after entering the second sensing mode.
