Electronic device and method for changing display area of display

An electronic device comprising:

• a first housing;
• a second housing slidably coupled to the first housing;
• a flexible display disposed on a surface formed by the first housing and the second housing, which is insertable in the second housing or extractable from the second housing;
• a motor configured to insert the flexible display in the second housing or extracting the flexible display from the second housing;
• an integrated circuit configured to control voltage related to the motor;
• at least one sensor;
• and
• at least one processor operably coupled with the flexible display, the motor, the integrated circuit, and the at least one sensor, wherein the at least one processor is configured to:
• identify, through the at least one sensor, data of temperature related to the flexible display,
• identify, through the at least one sensor, whether a size of a display area of the flexible display is maintained, increases or decreases,
• determine voltage to be applied to the motor based on whether the size of the display area of the flexible display is maintained, increases or decreases, and the data of temperature related to the flexible display, and
• change the display area of the flexible display by controlling the integrated circuit to apply the determined voltage to the motor.

• apply, based on a pre-designated number of pulses, pre-designated voltage to the motor for changing the display area of the flexible display,
• after applying, based on the pre-designated number of pulses, the pre-designated voltage to the motor, identify whether the state of the flexible display is different from a pre-designated state of the flexible display reached after applying, based on the pre-designated number of pulses, the pre-designated voltage to the motor when a step-out of the motor does not occur,
• identify a step-out rate of the motor when the state of the flexible display is different from the pre-designated state,
• identify, through the at least one sensor, data of temperature related to the flexible display,
• determine, based on the step-out rate of the motor, the pre-designated voltage, and the data of temperature related to the flexible display, voltage to be applied to the motor, and
• change the display area of the flexible display by controlling the integrated circuit to apply the determined voltage to the motor.
