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 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.

Abstract: A display device includes a display panel, an input sensor disposed on the display panel and sensing an input during a sensing frame period, a display controller receiving a vertical synchronization signal and a horizontal synchronization signal and controlling driving of the display panel in response to the vertical synchronization signal and the horizontal synchronization signal, and a sensor controller providing a transmission signal including a plurality of sampling periods to the input sensor. The display controller provides frequency information of a display frame period to the sensor controller using at least one of the vertical synchronization signal and the horizontal synchronization signal, and the sensor controller controls the number of the sampling periods of the sensing frame period based on the frequency information.

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.
