Display apparatus and displaying method thereof

A display apparatus, comprising:

• a display;
• a memory configured to store at least one program including instructions;
• and
• a processor configured to execute the instructions stored in the memory to:
• control the display to display a first user interface (UI) comprising an application list including an application program icon corresponding to an application program which is installable, and
• based on receiving a user input for installing the application program corresponding to the application program icon in the application list, control to receive, from an external apparatus, data via a transceiver coupled to the processor, to install the application program corresponding to the application program icon,
• wherein the processor is further configured to:
• based on the installation of the application program being started according to the user input, start displaying, in a second UI, the application program icon with a predetermined graphic effect for representing that the application program corresponding to the application program icon is being installed, while the application program is being installed, the application program icon with the predetermined graphic effect representing an installation progress status of the application program corresponding to the application program icon, and
• based on a completion of the installation of the application program, stop providing the predetermined graphic effect to the application program icon.

A method of controlling a display apparatus, the method comprising:

• displaying a first user interface (UI) comprising an application list including an application program icon corresponding to an application program which is installable;
• based on a user input for installing the application program corresponding to the application program icon in the application list being received, receiving data via a transceiver from an external apparatus to install the application program corresponding to the application program icon;
• based on the installation of the application program being started according to the user input, start displaying, in a second UI, the application program icon with a predetermined graphic effect applied to the application program icon to indicate that the application program corresponding to the application program icon is being installed, while the application program is being installed, the predetermined graphic effect representing an installation progress status;
• and
• based on a completion of the installation of the application program, stopping providing the predetermined graphic effect to the application program icon.
