Slidable electronic device and method therefor

A slidable electronic device comprising:

• memory, including one or more storage media, storing instructions;
• a housing including a first housing part and a second housing part that is movably engaged with the first housing part;
• an actuator configured to move the second housing part with respect to the first housing part;
• a flexible display coupled to the first housing part and the second housing part such that a size of an area of the flexible display that is visible from a front side of the housing changes as the second housing part is moved with respect to the first housing part;
• and
• one or more processors,
• wherein the instructions, when executed by the one or more processors individually or collectively, cause the slidable electronic device to:
• receive, while a screen is displayed on the area with a first size, an input for changing a size of the area from the first size to a second size larger than the first size,
• in response to the input received while the screen is displayed on the area in a first refresh rate, control the actuator to move the second housing part with respect to the first housing part such that the change from the first size to the second size is completed during a first time, and
• in response to the input received while the screen is displayed on the area in a second refresh rate higher than the first refresh rate, control the actuator to move the second housing part with respect to the first housing part such that the change from the first size to the second size is completed during a second time shorter than the first time.

One or more non-transitory computer readable storage media storing one or more computer programs computer-executable instructions when, when executed by one or more processors of a slidable electronic device including a housing including a first housing part and a second housing part that is movably engaged with the first housing part, an actuator configured to move the second housing part with respect to the first housing part, and a flexible display coupled to the first housing part and the second housing part such that a size of an area of the flexible display that is visible from a front side of the housing changes as the second housing part is moved with respect to the first housing part individually or collectively, cause the slidable electronic device to perform operations, the operations comprising:

• receiving an input for extending the area, while a screen is displayed on the area;
• controlling, in response to the input, the actuator to move the second housing part with respect to the first housing part;
• and
• causing, while the area is extended in accordance with the second housing part being moved with respect to the first housing part in response to the input, the flexible display to change a refresh rate of the screen that is extended on the area, according to a rate at which the area is extended.
