That is, the user can set a person or service to use the content to be displayed on the background screen.

In addition, the user selects a file to be set as a wallpaper through a file manager or a multimedia gallery application, and sets a target (electronic device, home appliance device, other contact (family member), social network, cloud server sharing the wallpaper), and the like. Can.

In addition, the user can capture a video clip through the camera application and immediately send it to the background of the desired object.

In addition, the user can connect the event and the content set through the timer or alarm application or calendar application.

In addition, the user can connect specific messages and contents through an electronic mail application or an SMS application.

In addition, the user may subscribe or select some content to be set as a wallpaper through a social media client application (Facebook, Twitter, YouTube, or other application providing content to be displayed).

When setting a background screen, a source (source) and a destination (content) of content to be displayed on the background screen may be mixed. For example, the user selects an event (birthday) from the calendar in the calendar application. You can register an invitation or reminder as content by starting the camera application. Alternatively, the content to be displayed in the selected event may be selected as a file stored in the electronic device, or some videos may be selected from You Tube. In the next step, the user selects an object (eg, the user himself, other contacts or objects that have agreed to receive the wallpaper). Users can record invitations for their birthday party, send them to social media pages (e.g. Facebook) selected contacts according to reminders, selected contacts, all users who have accepted the wallpaper and social media. .

Specifically, the user of the electronic device 200 may set a specific date (for example, an anniversary, Christmas, birthday, etc. set by the user) on the electronic device 200 as a trigger condition of specific content. When a specific date arrives, the electronic device 200 may display specific content on the background screen. At this time, the electronic device 200 may transmit the specific content to the synchronized electronic device 1120 so that the specific content is also displayed on the synchronized electronic device 1120. Here, the synchronized electronic device 1120 may be another user's electronic device set by the user in the electronic device 200.

Also, a user of the electronic device 200 may set a trigger condition of a specific content in a specific place in the electronic device 200. For example, when it is detected that the electronic device 200 reaches a specific place through GPS, the electronic device 200 may display specific content on the background screen. At this time, the electronic device 200 may transmit the specific content to the synchronized electronic device 1120 so that the specific content is also displayed on the synchronized electronic device 1120. Here, the synchronized electronic device 1120 may be another user's electronic device set by the user in the electronic device 200.

The present disclosure takes a social media approach that allows users to refresh their wallpaper on a regular basis and trigger desired content. In addition, the content may be triggered by a basic application installed on the electronic device 200 such as a calendar, an alarm, or a GPS location, and may also be triggered by an external application (eg, SNS) of another user.

The present disclosure can share content updated on the SNS server with other users without a separate application, and can display content even on a device that does not have access to SNS, such as a smart TV or a smart refrigerator. That is, the electronic device can display content on the background screens of a plurality of synchronized electronic devices.
