The cover is positioned on the main body through the clip inserted in the engaging slot. The locking wings are pivotally coupled to the cover. Each locking wing rotates toward the box to press elastic arms. The elastic arms drive the clips to be disengaged from the engaging slots. Thus, the cover is separated from the box.

Abstract: A planning method for a displaying device, comprising: read and decode a device description file with a host of a planning system; display a planning interface on a screen via the host; take an object configuration step to configure at least one graphical object to the at least one display page and set an object parameter of the at least one graphical object; generate a corresponding graphical user interface configuration file via the host. When the planning system is connected to the displaying device, the host transmits the graphical user interface configuration file to the displaying device. A microcontroller of the displaying device displays a corresponding graphical user interface on the displaying module based on the graphical user interface configuration file. In this way, the operation time for the user to plan the graphical user interface could be effectively saved.
