The handwriting pen comprises a pen point, a pen tube, a circuit board and a pressure detection piece. The nib is connected with one end of the pen tube, and at least part of the nib is positioned outside the pen tube. The circuit board is positioned in the pen tube. The pressure detecting piece is fixed on the outer side wall of the pen tube. The circuit board is connected with the pressure detection piece, and the pressure detection piece is used for generating an electric signal when being pressed and sending the electric signal to the circuit board. The pressure detection part is arranged on the outer side wall of the pen tube, generates an electric signal when being pressed and sends the electric signal to the circuit board, and the circuit board can send the electric signal to the display device to start the whiteboard interface or annotation function of the display device. Therefore, when a user uses the handwriting pen, the whiteboard interface or annotation function in the display device can be started by only applying force to the pressure detection piece on the pen tube, and the influence of the placement position of the handwriting pen is avoided.
