Electronic device and method for driving display of electronic device

An electronic device comprising:

• a display comprising a first region exposed on a front surface of the electronic device and a second region accommodated inside the electronic device in a hidden position and exposed to an outside of the electronic device in an exposed position;
• at least one sensor configured to detect a change in a display structure of the display;
• at least one display processor configured to control driving of the display;
• and
• a main processor,
• wherein the main processor is configured to:
• in response to a determination that the second region is in the hidden position and a view region on which image data is to be displayed is identified as the first region, drive the display at a first frame rate on a basis of a resolution corresponding to a size of the first region and the second region;
• display image data on the first region of the display;
• identify, when the second region changes from being in the hidden position to being in the exposed position according to the change in the structure of the display, a size of the view region;
• in response to a determination that the view region is changed to include the first region and at least a part of the second region, drive the display at a second frame rate lower than the first frame rate on the basis of the resolution;
• and
• display image data on the first region and the at least a part of the second region.
