That is, when the edge position of the flexible display screen 200 reports touch coordinates, the capacitive sensor simultaneously reports the sensing position, and the processor calculates the precise position pressed by the human hand based on the coordinates reported by the flexible display screen 200 and the coordinates reported by the capacitive sensor. In addition, when the first pressing part 301 and the second pressing part 301 are designed as touch display structures, they can also be used as an expansion of the display area of the main display screen (flexible display screen 200), making the whole machine look invisible. borders, increasing the display area and enriching the display effects. For example, the pressing member 300 can display different animations or text in different scenes. For example, it can be used to display weather, mobile phone signal, and volume. It can replace the current display area at the top of the mobile phone, so that the main screen of the mobile phone has a larger area for display. At the same time, the pressing member 300 can still display some information, such as WeChat messages and missed call reminders, when the home screen is in sleep mode. Messages can also be displayed synchronously when the home screen is used. For example, when watching a movie on the home screen, the pressing member 300 displays WeChat messages and SMS messages, so as not to interrupt the rhythm of watching the show.

Another application scenario of the electronic device in the embodiment of the present application is: when the main screen of the folding machine is folded, the pressing member 300 can be used to detect the folding state of the folding machine. For example, when more than 10 (points) in a circle of pressure sensors report pressure events and the pressure is within the "factory calibration value range", the processor determines that the entire machine is in a folded state at this time, and the display is switched from the large screen (main screen) Set it to a small screen (secondary screen) or close the main screen.
