An electronic device, comprising:

• a main body apparatus comprising a processing unit which generates a first image and performs display control;
• a fixing apparatus connected with the main body apparatus, which has at least a fixed state in which the fixing apparatus can be at least a part of an annular space or an approximate annular space meeting a first predetermined condition, the annular space or the approximate annular space being capable of surrounding an outer side of a cylinder meeting a second predetermined condition;
• a display unit arranged on the main body apparatus or the fixing apparatus, which outputs the first image;
• and
• a sensor unit arranged on the main body apparatus or the fixing apparatus, which generates a first control signal when sensing that the first predetermined condition is met, the processing unit controlling the on/off of the display unit according to the first control signal;
• wherein the display unit comprises a first display component which displays the first image, and a first optical component which is capable of at least receiving light corresponding to the first image emitted from the first display component, and changing the light path of the light corresponding to the first image to form a magnified virtual image corresponding to the first image,
• the display unit is capable of displaying image with two display modes;
• and
• the processing unit controls the display unit to switch between a first display mode and a second display mode when a third predetermined condition is met;
• the display image viewed by the user is a real image in the first display mode, and the display image viewed by the user is a virtual image in the second display mode.
