Abstract: Disclosed is an electronic device having a variable screen size and in which a degradation boundary may be set based on a total accumulated value. The display having the variable screen size may be partitioned into a plurality of virtual regions, based on the set degradation boundary. Accordingly, the degradation may be compensated with respect to each of the virtual regions.

Abstract: An electronic device may include a first housing, a second housing, a flexible display including a first area and a second area, wherein the first area is exposed for view to the outside of the electronic device in a first state, and when the first state is switched to a second state according to movement of the second housing with respect to the first housing, at least a portion of the second area may be exposed for view to the outside of the electronic device together with the first area, and a processor. The processor may be configured to, in the first state, supply power related to driving of the flexible display to a first portion of the second area, the first portion being adjacent to the first area and not exposed for view to the outside through a front surface of the electronic device.
