Abstract: An electronic device is provided. The electronic device includes a housing including a first plate, a second plate, and a third plate connecting the first plate and the second plate to be pivotable from a folded state of the first plate and the second plate to an unfolded state, a flexible display extending from the first plate across the third plate to the second plate, and at least one waterproofing member disposed on two lengthwise opposite ends of the third plate. The first plate may include at least one first recessed portion recessed inward from at least a portion of an edge of the first plate. The second plate may include at least one second recessed portion recessed inward from at least a portion of an edge of the second plate. At least a portion of the third plate may include a portion formed in a lattice pattern. The third plate may be formed to be shorter in length than the first plate and the second plate. The at least one first recessed portion and the at least one second recessed portion may be disposed in two lengthwise opposite ends of the third plate.

Abstract: Various embodiments of the present invention relate to a method for controlling an actuator. The present invention can detect a haptic generation event through a sensor unit, check data of an actuator and data of a human receptor stored in a memory in response to the haptic generation event, calculate a driving voltage of the actuator on the basis of the checked data of the actuator and the checked data of the human receptor, and drive the actuator with the calculated driving voltage. Other embodiments are also possible.
