TOUCH SENSING SYSTEM DISPLAY DEVICE ACTIVE PEN AND PEN RECOGNIZING METHOD

摘要

Embodiments of the present invention relate to a touch sensing system, a display device, an active pen, and a pen recognizing method. More specifically, the present invention relates to the touch sensing system, the display device, the active pen, and the pen recognizing method, which allow an active pen to provide pen identification information to a display device through a predetermined path, thereby rapidly and accurately recognizing the pen. Also, various active pens are distinguished and recognized, thereby simultaneously processing pen input through the various active pens. The touch sensing system comprises: the active pen; and the display device including a panel in which multiple touch electrodes are located and performing a pen recognition process in cooperation with the active pen.
