Abstract: An electronic device includes: a display layer; a sensor layer on the display layer, and including: a first electrode, and a second electrode adjacent to the first electrode; and a plurality of crossing electrodes; and a driving circuit electrically connected to the sensor layer to control an operation of the sensor layer. The sensor layer is to operate in a first touch mode to sense a first input signal, and a second touch mode to sense a second input signal of an input device to discharge a magnetic field, and the driving circuit is to sense coordinates of the input device based on a signal profile measured based on a first current having a first current direction formed in the first electrode by the input device, and a second current having a second current direction opposite to the first current direction formed in the second electrode by the input device.

Abstract: A pen analog front end includes an analog signal processing unit connected with an input sensor. The analog signal processing unit processes an analog input signal that the input sensor receives from an input device. An analog-to-digital converter converts the analog input signal into a first digital input signal. A digital signal processing unit synchronizes the first digital input signal and reference sync data preset to the input sensor and processes a position signal and a data signal of the input device.
