An electronic device according to an embodiment includes: a display panel; a touch electrode layer disposed on the display panel and comprising at least one touch electrode; and a conductive wire disposed on the display panel, disposed on the same layer as the touch electrode layer, and generating a magnetic field signal for driving a stylus pen.

Electronic device, stylus pen, and method for detection of a position of the stylus pen on the electronic device

An embodiment of the present invention provides a display device including: a loop coil; a display unit configured to include a plurality of pixels; a display driver configured to apply a data signal and a scan signal to the pixels depending on a vertical synchronization signal and a horizontal synchronization signal; a plurality of touch electrodes positioned on the display unit; a driving receiver configured to apply a driving signal to the loop coil during a first period and to receive a sensing signal from at least one of the touch electrodes during a second period after the first period; and a controller configured to generate touch information by using the sensing signal, wherein the driving signal is synchronized to at least one pulse of the vertical synchronization signal and the horizontal synchronization signal.

Stylus pen, antenna module, touch sensor, and electronic device

An embodiment of the present disclosure provides a touch apparatus including: a touch sensor; and a touch controller operating in a full driving mode for applying a first driving signal for generating a resonance signal of a stylus pen to the touch sensor and a skip driving mode in which a second driving signal having a period having an off-duty different from that of the first driving signal is applied to the touch sensor, and obtaining touch coordinate information from a detection signal received from the touch sensor.

Touch device using resonance signal of stylus pen and touch detection method thereof

A touch apparatus according to an exemplary embodiment includes: a touch panel that includes a plurality of first touch electrodes extending in a first direction and arranged in a second direction that crosses the first direction, and a plurality of second touch electrodes extending in the second direction and arranged in the first direction; and a touch driver that applies a first driving signal for generation of a resonance signal of a stylus pen to the touch panel in a first section, and receives a detection signal from the touch panel in a second section that is next to the first section, wherein the touch driver applies a driving signal of which a ratio of a disable level section with respect to an enable level section within one iterative period is different from that of the first driving signal in the second section, to the touch panel.
