The projection module can select a first data path corresponding to the projection file according to needs to transmit the projection file, and the touch screen displays the projection file.
With reference to fig. 4 and the specific embodiment, the second electronic device sends the projection data to the screen projecting module of the first electronic device through wireless communication, the screen projecting module converts the projection data into data transmitted by its internal interface (such as HDMIIN) based on a preset communication protocol, and sends the data to the controller in the first electronic device through the internal interface, the controller may also be connected to the embedded controller and controlled or coordinated by the embedded controller (providing 5V power), after receiving the data, the controller will form a projection file with the data selection switch and display the data on the touch screen, and control the touch screen not to display the data sent by the display card, in addition, the embedded controller may control the touch screen through the touch selection switch, so that the touch screen is in the first state of touch operation by the operating system, and converting the first state into a second state for touch control in cooperation with the screen projection module.
In one embodiment of the present application, the connection module is further configured to: the embedded controller of the first electronic device provides power to detect the first control command. The embedded controller is a single chip microcomputer, controls the time sequence of most important signals in the starting process of the electronic equipment, is always in a starting state particularly in a notebook computer and an all-in-one machine, and keeps running and waits for instructions of a user no matter whether the electronic equipment is in a starting state or a shutdown state. Therefore, in this embodiment, the connection module may provide the continuous power through the embedded controller to detect the first control instruction, and the connection module may further control the first display screen or the entire projection assembly, for example, wake up the projection assembly.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
