Abstract: A connection method for wireless display is provided. The connection method includes: activating by a mobile device an application program; acquiring by the mobile device a two-dimensional barcode image; determining by the mobile device whether the two-dimensional barcode image is identical with a prestored image, if not, processing the two-dimensional barcode image to obtain a WiFi MAC address; determining by the mobile device whether the format of the WiFi MAC address is correct, if so, storing the two-dimensional barcode image and its corresponding WiFi MAC address; broadcasting by the mobile device the WiFi MAC address to a WiFi display module of the mobile device, and establishing a data connection with the WiFi display module via the WiFi MAC address; performing data transmission by the mobile device with the display device.

Abstract: A wireless projection system and a wireless projector are disclosed. The wireless projector comprises a WiFi screen-mirroring receiving module, a control module and a projector module. The WiFi screen-mirroring receiving module is configured to receive a wireless signal for WiFi screen-mirroring and transform the wireless signal into a first signal; and the control module is configured to obtain the first signal from the WiFi screen-mirroring receiving module and control the projector module to project a screen according to the first signal. In the aforesaid way, the present disclosure can achieve projection through WiFi screen-mirroring.

Abstract: A system and method for external display is disclosed. The system includes: a mobile device comprised of a first communication module, a storage module configured to store at least a first interface and a second interface, and a processing module connected to the first communication module and the storage module; a display device including a second communication module and a display module. The processing module generates external display information and broadcasts the external display information through the first communication module. The second communication module acquires the external display information and transmits information of the display device to the processing module based on external display information. The processing module determines whether the display device is in accordance with the second interface based on information of the display device, if so, the mobile device transmits the second interface to the display device to make the display device display the second interface.
