1. A video projection switching apparatus, comprising a screen interface, a display controller, a power module, a switching unit, and a plurality of input interfaces;
wherein at least two input interfaces of the plurality of input interfaces are electrically connected to the display controller and used for connecting to external input devices to input video signals; at least one input interface of the plurality of input interfaces is electrically connected to the power module and used for connecting to a power supply; the screen interface is used for connecting to a display screen; and the display controller is electrically connected to the power module, the switching unit, and the screen interface, respectively;
when at least two input interfaces both input video signals, the display controller first outputs a video signal input from one input interface of the at least two input interfaces through the screen interface according to a preset program; the switching unit outputs a switching signal to the display controller when a user operates, and when the display controller receives the switching signal, the display controller selects to output a video signal input from another input interface of the at least two input interfaces through the screen interface; and the power module processes power input from one input interface of the at least one input interface and then supplies the power to the display controller for use.
