An electronic apparatus, comprising:

• a display unit, having a full-screen display mode and a block display mode, wherein in the full-screen display mode, the whole display unit serves as a displaying frame;
• in the block display mode, a designated block on the display unit serves as the displaying frame;
• a switching unit, coupled to the display unit and switching the full-screen display mode to the block display mode according to a mode-switching signal;
• and
• a processing unit, coupled to the display unit, wherein upon receiving the mode-switching signal, the processing unit enables a corresponding operation interface according to an execution state of an operation system of the electronic apparatus in the full-screen display mode and displays the operation interface in the designated block,
• wherein the execution state in the full-screen display mode is an application executing in the full-screen display mode, the operation interface displayed in the designated block corresponds to the application executing in the full-screen display mode, the operation interface is different from an interface of the application executing in the full-screen display mode, a size of the operation interface matches a size of the designated block, the operation interface provides a simple operation function corresponding to the application executing in the full-screen display mode, and the simple operation function is a part of functions provided by the application executing in the full-screen mode.
