According to one embodiment of the present invention, an apparatus for sensing touch pressure includes: a touch pen including a pen tip having a conductive fluid; a touch sensor including a plurality of driving electrodes and a plurality of sensing electrodes; and a control unit determining touch pressure based on a contact surface between the pen tip and the touch sensor. Therefore, the apparatus can sense pen pressure of the touch pen applied by a user based on a change in the contact surface between the pen tip of the touch pen and the touch sensor by simply using the touch pen including the fluid pen tip at a minimum cost without installing a separate pressure sensor. |
