Foldable display device with interactable user interface surface on the external shell

A method for controlling content to be displayed on a foldable display device, comprising:

• detecting an input on a user interface surface located on an exterior cover section of the foldable display device, wherein the foldable display device is in a closed state that includes a first section and a second section of the foldable display device being in a face-to-face configuration, and the user interface surface being on a reverse side of the first section;
• identifying the input as an object produced on the user interface surface;
• associating the object produced on the user interface surface with text that is produced on the user interface surface, where the object and the text are produced via user interaction on a top surface of the user interface surface;
• and
• storing the object and the associated text for display on one or more of the user interface surface or a plurality of display screens located on an interior section of the foldable display screen, wherein the object is displayed on at least one of the plurality of display screens on the interior section when the foldable display device transitions from the closed state to an open state.

A non-transitory computer-readable medium for controlling content to be displayed on a foldable display device, comprising code for:

• detecting an input on a user interface surface located on an exterior cover section of the foldable display device, wherein the foldable display device is in a closed state that includes a first section and a second section of the foldable display device being in a face-to-face configuration, and the user interface surface being on a reverse side of the first section;
• identifying the input as an object produced on the user interface surface;
• associating the object produced on the user interface surface with text that is produced on the user interface surface, where the object and the text are produced via user interaction on a top surface of the user interface surface;
• and
• storing the object and the associated text for display on one or more of the user interface surface or a plurality of display screens located on an interior section of the foldable display screen, wherein the object is displayed on at least one of the plurality of display screens on the interior section when the foldable display device transitions from the closed state to an open state.
