Abstract: An electronic device includes a display panel, an input sensor disposed on the display panel and including first sensing electrodes extending in a first direction and second sensing electrodes extending in a second direction crossing the first direction, and a sensor controller connected to the input sensor. First and second areas are defined in the input sensor based on an input position to which an input by an input device is applied. The input position is located in the first area and not in the second area. The sensor controller applies a first signal to at least one first sensing electrode disposed in the first area and at least one second sensing electrode disposed in the first area and applies a second signal having an opposite phase to a phase of the first signal to the other first and second sensing electrodes disposed in the second area.

Abstract: An electronic device may include a display layer that displays an image and a sensor layer disposed on the display layer and sensing an external input. The sensor layer includes a plurality of channels equal to M. M is an integer greater than or equal to 5. A sensor driver drives the sensor layer. In an uplink section, the sensor driver provides an uplink signal to X first channels that are continuously arranged and provides an inverse phase signal having an inverse phase of the uplink signal to Y second channels that are continuously arranged. X and Y are integers greater than or equal to 2. Z off channels that are continuously arranged and are positioned between the first channels and the second channels may be turned off is an integer greater than or equal to 1. M is a sum of X, Y and Z.

Abstract: An electronic device includes a display panel, an input sensor, a panel driver, and a sensor controller. The panel driver drives the display panel at a first operating frequency in a first driving mode and drives the display panel at a second operating frequency lower than the first operating frequency in a second driving. The display panel displays the image in units of first driving frames in the first driving mode and displays the image in units of second driving frames in the second driving mode. The sensor controller transmits a first mode uplink signal to the input sensor in a first scheme in the first driving mode and transmits a second mode uplink signal to the input sensor in a second scheme different from the first scheme in the second driving mode.
