1. A method for switching display mode, wherein the method is applied to an electronic device having a plurality of display units and the electronic device comprises at least a first display mode and a second display mode, wherein each display unit corresponds to one display channel, each display channel corresponds to at least one display unit, the electronic device has pre-stored a corresponding relation between the display channel and the display unit, and the method comprises:

  • detecting whether a first instruction is received and obtaining a first detection result, in the case that the electronic device is in the first display mode, wherein the first instruction is for switching a display mode of the electronic device from the first display mode to the second display mode;

    stopping synthesizing current data to be displayed in the first display mode and determining a second display unit corresponding to the second display mode if the first detection result shows that the first instruction is received, wherein the second display unit is one or more of the plurality of display units;

    storing information displayed currently by the display unit corresponding to the first display mode in response to receiving the first instruction, to restore display state of the display unit corresponding to the first display mode in the case that the display mode of the electronic device is switched back to the first display mode;

    determining a display channel corresponding to the second display unit, based on the corresponding relation between the display channel and the display unit; and

    synthesizing current data to be displayed in the second display mode, and transmitting the current data to be displayed in the second display mode to the second display unit corresponding to the second display mode via the determined display channel, to display it,wherein one of the first display mode and the second display mode is an independent mode, and another of the first display mode or the second display mode is an extended mode,wherein in the independent mode, data of a first application is transmitted to only a single one of display units corresponding to the independent mode and data of a second application different from the first application is transmitted to only another single one of the display units corresponding to the independent mode,wherein in the extended mode, different data of only a single one of the first application or the second application is transmitted respectively to different display units corresponding to the extended mode,wherein the independent mode comprises at least a first display state and a second display state, andwherein, in the first display state, data of a first application is transmitted to only a first one of display units corresponding to the independent mode and data of a second application different from the first application is transmitted to only a second one of the display units corresponding to the independent mode and in the second display state, the data of the first application is transmitted to only the second one of the display units corresponding to the independent mode, orin the first display state, data of the first application and a third application is transmitted to only the first one of display units corresponding to the independent mode and data of the second application is transmitted to only the second one of the display units corresponding to the independent mode, and in the second display state, the data of the first application and the second application is transmitted to only the second one of the display units corresponding to the independent mode and the data of the third application is transmitted to only the first one of display units corresponding to the independent mode.
