Modular display apparatus and method for maintaining display performance

An electronic device comprising:

• a display comprising a first display module and a second display module;
• a communicator, comprising a communication circuit, for communicating with an external device;
• a processor;
• and
• a memory,
• wherein the memory stores instructions for configuring the processor to:
• store first data obtained from the first display module and second data obtained from the second display module;
• control the communicator to transmit an average value of the first data obtained by accumulating the first data for a set period and an average value of the second data obtained by accumulating the second data for a set period to an external device and receive third data including whether to change positions of the first display module and the second display module obtained by the external device;
• and
• display guide information requesting a change of positions of the first display module and the second display module, using the third data,
• wherein the third data is obtained using the average value of the first data and the average value of the second data.

A server comprising:

• a communicator comprising a communication circuit;
• a processor;
• and
• a memory,
• wherein the memory stores instructions for configuring the processor to:
• receive an average value of first data obtained by using the first data obtained from a first display module and an average value of second data obtained using the second data obtained from a second display module, via the communicator;
• obtain third data including whether to change positions of the first display module and the second display module, using the average value of the first data and the average value of the second data;
• and
• control the communicator to transmit the third data to an external device.

A method for controlling an electronic device, the method comprising:

• storing first data obtained from a first display module and second data obtained from a second display module;
• obtaining an average value of the first data by accumulating the first data for a set period and obtaining an average value of the second data by accumulating the second data for a set period;
• and
• displaying guide information requesting a change of positions of the first display module and the second display module, using the average value of the first data and the average value of the second data.
