Electronic device including flexible display and operation method thereof

A method by an electronic device, the method comprising:

• displaying, on a first area of a display of the electronic device, a first execution screen of a first application at a first screen ratio corresponding to a size of the first area in an unfolded state of the electronic device;
• based on switching to a folded state of the electronic device, changing the first screen ratio of the first execution screen into a second screen ratio corresponding to a size of a third area of the display;
• obtaining a first image corresponding to the first execution screen changed to the second screen ratio;
• displaying the first image on the third area by applying a visual effect of moving the first image from the first area to the third area of the display via a second area of the display, and displaying the first execution screen changed to the second screen ratio on the third area by replacing the first image;
• and
• based on switching from the folded state to the unfolded state, displaying, on the first area, the first image corresponding to the first execution screen displayed on the third area by applying a visual effect of moving the first image from the third area to the first area via the second area, and displaying the first execution screen changed to have the first screen ratio on the first area by replacing the first image.

A non-transitory recording medium for storing a program comprising instructions that cause, when executed by a processor of an electronic device, the electronic device to:

• display, on a first area of a display of the electronic device, a first execution screen of a first application at a first screen ratio corresponding to a size of the first area in an unfolded state of the electronic device;
• based on switching to a folded state of the electronic device, change the first screen ratio of the first execution screen into a second screen ratio corresponding to a third area of the display ratio corresponding to a size of a third area of the display;
• obtain a first image corresponding to the first execution screen changed to have the second screen ratio;
• display the first image to and on the third area by applying a visual effect of moving the first image from the first area to the third area of the display via a second area of the display, and display the first execution screen changed to have the second screen ratio on the third area by replacing the first image;
• and
• based on switching from the folded state to the unfolded state, display, on the first area, the first image corresponding to the first execution screen displayed on the third area by applying a visual effect of moving the first image from the third area to the first area via the second area, and display the first execution screen changed to have the first screen ratio on the first area by replacing the first image.
