1. A display screen switching method for a monitor which comprises a host comprising a controller, a memory, a parameter module, and a first display communicatively connected to the host, the first display being a local display of the monitor, wherein the controller of the monitor controls display screen switching between the first display and a second display external of the monitor, the display screen switching method comprising:
displaying, on the first display, first frame data corresponding to one or more first physiological parameters according to a first display file, the first display file being stored in the memory and specifying the one or more first physiological parameters and information of a first interface layout and first interface elements based on the first display;
detecting, by the controller of the monitor, whether the second display is connected to the monitor;
in response to detecting that the second display is connected, further determining, by the controller of the monitor, whether a first display screen switching instruction is received, the first display screen switching instruction being generated based on an operation or a gesture of a user;
in response to determining that the first display screen switching instruction is received:
acquiring, by the controller of the monitor, a second display file from the memory of the monitor or the second display, the second display file specifying one or more second physiological parameters and information of a second interface layout and second interface elements based on the second display;
acquiring data of the one or more second physiological parameters specified by the second display file from the parameter module of the monitor;
generating, by the controller of the monitor, second frame data using the data of the one or more second physiological parameters according to the second display file;
controlling to display, by the controller of the monitor, the second frame data on the second display external to the monitor; and
controlling the first display to turn into a black screen when the second display displays the second frame data corresponding to the one or more second physiological parameters;
during the second frame data being displayed on the second display, determining whether a second display screen switching instruction is received on the first display that has been turned into the black screen; and
in response to determining that the second display screen switching instruction is received:
acquiring data of the one or more first physiological parameters specified by the first display file from the parameter module of the monitor;
generating, by the controller of the monitor, third frame data using the data of the one or more first physiological parameters according to the first display file;
controlling to turn on the first display that has been turned into the black screen to display the third frame data on the first display; and
controlling the second display to turn into a black screen when the first display displays the third frame data.
