The slider can be divided into a part that can enter the inside of the housing (hereinafter referred to as an inlet part) and a part that remains exposed to the outside. A slide-out state in which the inlet part of the slider is completely withdrawn from the housing (in other words, first state, open state, extended state, roll-out state) In this case, the entire display (or most of the display area) may be exposed to the outside through the front. As the insertion portion of the slider is retracted into the housing, the display can also be retracted into the housing. The display also has a part that remains exposed to the outside (e.g., first display area, first section) and a part that can enter the inside of the housing (e.g., second display area, second section, bendable section). ) can be divided into: Slide-in state in which the entire inlet part of the slider is inserted into the housing (in other words, second state, closed state, reduced state, roll-in) state), the entire second display area of the display may be retracted into the housing. According to one embodiment, when the state is changed from the slide-out state to the slide-in state, a part of the display (eg, the second display area) may not be retracted into the housing, but may be moved to the rear via the side. As illustrated above, the electronic device 101 may have a sliding structure in which a portion of the display is retracted into the housing, or a sliding structure in which a portion of the display is moved from the front to the back.

According to one embodiment, the state of the electronic device 200 may be defined based on the curvature (degree of bending) of a designated portion of the display 230. For example, if the curvature of the second display area 232 corresponds to a value (or within a range) indicating concave (or convex), the state of the electronic device 200 may be defined as a slide-in state. . When the curvature of the second display area 232 corresponds to a value (or within a range) indicating flatness, the state of the electronic device 200 may be defined as a slide-out state.

Based on the state of the electronic device 200, an active area on the display 230 in which visual information (eg, navigation bar, status bar, application execution screen) will be displayed may be determined. For example, when the electronic device 200 is in a slide-in state, the active area is determined to be the first display area 231, and visual information may be displayed in the first display area 231 accordingly. When the electronic device 200 is in a slide-out state, the active area is determined to be the entire area of the display 230 (e.g., the first display area 231 and the second display area 232), and accordingly, the entire area is visually Information may be displayed.
