Embodiments of the present invention relate to the field of electronic communications, and in particular, to a method and a device for automatically displaying an application component on a desktop. In the method and the device that are provided by the embodiments of the present invention, a mobile terminal collects preset information first; matches the collected information with scenario information in a scenario saved by the terminal; and when the collected information matches scenario information in a scenario saved by the terminal, automatically displays an application component in the scenario on a desktop. Therefore, the process of manually searching for an application component by a user is omitted, thereby solving the problem that operations of starting an application component are complex and the operations are time-consuming. Therefore, the method and the device that are provided by the embodiments of the present invention can realize automatic display of an application component on a desktop, so that a terminal automatically displays an application component in a scenario corresponding to currently collected information on the desktop, and a user can directly start a corresponding application component on the desktop, thereby simplifying operations of starting the application component and saving time for the operations.
