Electronic device for sensing and compensating for deterioration caused in display

A method of detecting and compensating for deterioration of pixels included in a display or another display of an external device, the method comprising:

• obtaining by using a camera or receiving from the external device by using a communication circuit, a first image corresponding to a first display image having a uniformly repeated pattern and output through the display or the other display included in the external device;
• obtaining by using the camera or receiving from the external device by using the communication circuit, a second image corresponding to a second display image having a same gradation and output through the display or the other display;
• identifying one or more deteriorated pixels among a plurality of pixels included in the display or the other display by using the second image;
• determining location information of the one or more deteriorated pixels by using the uniformly repeated pattern included in the first image;
• and
• generating compensation information for the one or more deteriorated pixels based on the location information.

A server comprising:

• a communication circuit;
• and
• a processor electrically connected to the communication circuit,
• wherein the processor is configured to:
• receive, from a first external device by using the communication circuit, a first image corresponding to a first display image output through a display included in a second external device and having a uniformly repeated pattern;
• receive, from the first external device by using the communication circuit, a second image corresponding to a second display image having a same gradation and output through the display;
• identify one or more deteriorated pixels among a plurality of pixels included in the display by using the second image;
• determine location information of the one or more deteriorated pixels by using the uniformly repeated pattern included in the first image;
• generate compensation information for the one or more deteriorated pixels based on the location information;
• and
• transmit the generated compensation information to the second external device through the communication circuit.
