Electronic device

An electronic device comprising:

• a display layer comprising a display area for displaying an image, and a non-display area adjacent to the display area;
• a display driver for driving the display layer;
• a sensor driver;
• a processor for controlling an operation of the display driver and the sensor driver;
• and
• a sensor layer above the display layer, configured to be driven by the sensor driver, configured to selectively operate in a first mode for sensing a touch input, or a second mode for sensing a pen input and comprising a charge-driving mode, and comprising:
• first electrodes arranged in a first direction;
• second electrodes arranged in a second direction crossing the first direction;
• first charging electrodes arranged in the first direction;
• second charging electrodes arranged in the first direction and electrically insulated from the first charging electrodes;
• a first loop trace line electrically connected to the first charging electrodes;
• and
• a second loop trace line electrically connected to the second charging electrodes, and
• wherein the sensor driver is configured to apply a signal to at least a portion of the first charging electrodes to form a first loop in the charge-driving mode, and is configured to apply a signal to at least a portion of the second charging electrodes to form a second loop in the charge-driving mode.
