A display system comprising:

• a display apparatus comprising:
• a display panel;
• a first communicator configured to communicate with a service apparatus;
• a user interface configured to acquire a user input;
• and
• a first controller configured to:
• control the first communicator to transmit operation information comprising a total operating time and an operating temperature of the display apparatus, to the service apparatus;
• and
• the service apparatus configured to:
• based on receiving the total operating time and the operating temperature of the display apparatus, output update data for updating an image parameter for correcting degradation in image quality of the display apparatus,
• wherein the image parameter comprises at least one of a brightness level, a contrast, a sharpness level, and a color density of the display apparatus, and
• wherein the first controller is further configured to control the first communicator to transmit the operation information to the service apparatus based on acquiring a user input for powering off the display apparatus from the user interface.

A method of controlling a display apparatus, comprising:

• collecting operation information comprising a total operating time of the display apparatus and an operating temperature of the display apparatus;
• transmitting the operation information to a service apparatus;
• receiving, from the service apparatus, an image parameter for correcting degradation of image quality of the display apparatus;
• processing image data based on the received image parameter;
• and
• displaying an image corresponding to the processed image data,
• wherein the image parameter comprises at least one of a brightness level, a contrast, a sharpness level, and a color density of the display apparatus, and
• wherein the transmitting the operation information to the service apparatus further comprises transmitting the operation information to the service apparatus based on acquiring a user input for powering off the display apparatus.
