Claim 10:
11. A method for driving an electronic device including: a rollable display comprising a display area whose area is configured to be adjusted with a movement of at least a part of a housing in a first direction, the rollable display including a first area fixedly exposed to an outside and a second area configured to be variably exposed to the outside based on movement of the housing; and a 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, the method comprising:
obtaining the global burn-in information and the local burn-in information for each designated sampling period and storing the global burn-in information and the local burn-in information in the first memory area and the second memory area, respectively;
predicting 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;
predicting 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;
generating a first compensation map including local compensation data calculated to correspond to the m block areas based on it being predicted that the burn-in occurs at least partly in the boundary area;
generating a second compensation map including global compensation data calculated to correspond to the n block areas based on it being predicted that the burn-in occurs at least partly in a remaining area of the whole area excluding the boundary area; and
controlling the rollable display to display compensated image data based on the first compensation map and/or the second compensation map.
