The active pen includes a first electrode, a second electrode and a pressure sensor, where the first electrode is configured to output a first driving signal, the second electrode is configured to output a second driving signal when the pressure sensor detects a first pressure generated by the active pen. The method includes: when information of the first pressure is not received, determining whether the active pen is pressing the screen according to the second detecting signal; if it is determined that the active pen is pressing the screen, displaying handwriting of the active pen on the screen according to a second pressure, where the second pressure is a preset pressure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus and system for pressure detection, touch-control chip and electronic device","description":"A method for pressure detection is provided, which can avoid a delayed display of a writing pressure generated by the active pen on the screen.
