The invention provides an information transmission method. The information transmission method is applied in first electronic equipment, and comprises the following steps: when a certain specific application of the first electronic equipment is started and the first electronic equipment receives a first message corresponding to starting of the application, the first electronic equipment is controlled to display a third display content different from a first display content displayed before based on second display data; second electronic equipment is controlled to display a fourth display content based on cached third display data different from the second display data; furthermore, the fourth display content and the third display content are different; and the third display content can be a display content corresponding to a first message related application. Because the first electronic equipment is source equipment in a mirror image system and the second electronic equipment is mirror image equipment in the mirror image system, when a certain specific application program is started in the source equipment, the image content in a display screen of the source equipment cannot be synchronized in the mirror image equipment to display; and thus, the privacy security of source equipment users is ensured.
Description
technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, relates to an information transmission method and electronic equipment. Background technique [0002] Miracast (mirror) technology, as an emerging technology, has been widely used in electronic devices in various aspects such as office and life. [0003] Using this mirroring technology, the screen image displayed on a certain device A can be acquired in real time and sent to other devices for mirror display. displayed synchronously. [0004] However, in the prior art, once the mirroring device establishes a mirroring connection with the source device, all content displayed on the display screen of the source device will be displayed synchronously on the mirroring device without distinction. However, in some emergencies, such as when a call comes in, some private information of the source device user will also be synchronized to the mirror device for display, ca...
