Claim 0:
1. An electronic device comprising:
a housing;
a rollable display configured to be supported by the housing and provided with a display area whose area is configured to be adjusted via a movement of at least a part of the housing in a first direction, the rollable display including a first area fixedly viewable to an outside and a second area configured to be variably viewable to the outside based on the movement of the at least part of the housing;
a memory configured to store therein burn-in information of the rollable display, the memory including:
a first memory area configured to store global burn-in information corresponding to n designated block areas divided from a whole area of the display area including the first area and the second area, and
a second memory area configured to store local burn-in information corresponding to m designated block areas divided from a boundary area located on a boundary between the first area and the second area of the rollable display and having a designated width; and

a processor,
wherein the processor is configured to:
obtain the global burn-in information and the local burn-in information for each designated sampling period and control to store the global burn-in information and the local burn-in information in the first memory area and the second memory area, respectively,
predict whether a burn-in occurs at least partly in the whole area of the display area based on a result of analyzing the global burn-in information,
predict whether the burn-in occurs at least partly in the boundary area of the display area based on a result of analyzing the local burn-in information,
generate a first compensation map including local compensation data to correspond to the m block areas when it is predicted that the burn-in occurs at least partly in the boundary area,
generate a second compensation map including global compensation data to correspond to the n block areas when it is predicted that the burn-in occurs at least partly in a remaining area of the whole area excluding the boundary area, and
control the rollable display to display compensated image data based on the first compensation map and/or the second compensation map.
