Mobile electronic apparatus, accessory device therefor, and electronic apparatus including the accessory device

A mobile electronic apparatus comprising:

• a display unit including a display screen;
• a first sensor and a second sensor configured to obtain identification (ID) information of an accessory device by detecting a magnet or a memory attached to a battery cover, wherein the accessory device includes a display cover covering the display screen and the battery cover covering a battery;
• and
• a processor displaying a user interface (UI) screen corresponding to the accessory device on the display screen by driving a first program corresponding to the obtained ID information of the accessory device when the display screen is covered by the display cover,
• wherein the processor is configured to execute a second program to perform a general function of the mobile electronic apparatus based on the display cover being opened, and execute the first program to perform a function corresponding to the ID information of the display cover, that is read from the display cover, based on the display cover being closed, and
• wherein the ID information of the accessory device is discriminated according to a combination of output signals of the first sensor and the second sensor, the output signals being different based on at least one of a position, a number, and a size of the magnet, and a type of graphic user interface, among a plurality of types of graphic interfaces, to be displayed is uniquely identified based on the ID information when the display cover is fully closed.

An electronic apparatus comprising:

• a mobile electronic apparatus;
• and
• an accessory device comprising a cover covering a display screen of the mobile electronic apparatus, and a cover identification (ID) mark portion attached to the cover and identified by the mobile electronic apparatus,
• wherein the mobile electronic apparatus comprises:
• a display unit including the display screen;
• a first sensor and a second, sensor configured to obtain ID information of the cover by detecting the cover ID mark portion attached to the cover, when the display screen is covered by the cover;
• and
• a processor performing control such that a user interface (UI) screen corresponding to the cover is displayed on the display screen, by driving a first program corresponding to the obtained ID information of the cover,
• wherein the processor is configured to execute a second program to perform a general function of the mobile electronic apparatus based on the cover being opened, and execute the first program to perform a function corresponding to the ID information of the cover, that is read from the cover, based on the cover being closed, and
• wherein the ID information of the cover is discriminated according to a combination of output signals of the first sensor and the second sensor, the output signals being different based on at least one of a position, a number, and a size of the cover ID mark portion, and a type of graphic user interface, among a plurality of types of graphic interfaces, to be displayed is uniquely identified based on the ID information when the respective cover is fully closed.
