/**
    Display Control Object

    The display control object which provides unified interface for display device/engine control.
    The user can get the display object by API: disp_get_display_object() first, and then access the display engine through the
    display object. The disp_ctrl/disp_lyr_ctrl/dev_ctrl would not set load to activate the configurations, the user must set load
    after all the settings is done.
