    Abstract: An electronic device includes: a display layer; a sensor layer to operate in a first mode for detecting a first input by a touch, and a second mode different from the first mode and including a plurality of frames; and a sensor controller to control the sensor layer. Each of the plurality of frames includes a downlink signal including information used to detect a second input by an input device, and a sensing signal including information used to detect the first input. When the first input is detected in the second mode, the sensor controller is to: output first coordinates of the first input based on the sensing signal of at least one frame in which the first input is detected; and correct second coordinates of the second input based on the first coordinates during a period of at least two frames including the at least one frame.

    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. Z is an integer greater than or equal to 1. M is a sum of X, Y and Z.
