The invention discloses an active pen, a control method and device thereof and a handwriting display method and device, and belongs to the technical field of touch control. The active pen includes a first electrode, a plurality of second electrodes, and a control circuit. One end of the first electrode is a nib of the main moving pen. The second electrodes are arranged around the first electrode at intervals in the circumferential direction, gaps are formed between the second electrodes and the first electrode, and a capacitor is formed between the first electrode and each second electrode. Inthe writing process of the active pen, due to the fact that the pen point is stressed, the first electrode deviates, and the gap between the first electrode and the second electrode is changed. The second electrodes are controlled to send excitation signals respectively, and the frequencies of the excitation signals sent by the second electrodes are different. The first electrode receives the excitation signals sent by the plurality of second electrodes to obtain induction signals. According to the induction signal, the capacitance between the first electrode and each second electrode is determined, so that the offset direction and offset of the first electrode are determined, and the stress information of the pen point is further determined.
