Abstract
Disclosed is an electronic device including a display including a first part where a size viewed from an outside is constant and a second part where an area viewed from the outside is variable, a display driver integrated circuit (IC) configured to control the display, a memory, and a processor operatively connected with the display driver IC and the memory, wherein the processor is configured to, based on the area of the second part viewed from the outside, define a plurality of virtual regions including a first region and a second region adjacent to each other, based on an accumulated value of red, green, blue (RGB) values applied to each frame displayed on a screen, acquire color information of each of the plurality of virtual regions, based on an accumulated use time for each of the plurality of virtual regions and the color information, calculate a plurality of total accumulated values of each of the plurality of virtual regions, set a boundary, which is positioned between the first region and the second region, as a degradation boundary, when a difference value between a first total accumulated value of the first region and a second total accumulated value of the second regio…
