Abstract: An electronic device includes: a sensor module, a display module comprising a main display and a sub-display, a memory configured to store computer-executable instructions, and a processor configured to execute the instructions by accessing the memory, wherein the instructions, when executed by the processor, cause the processor to: identify at least one real object displayed through the main display, select one real object from among the identified at least one real object as a target object, control the sensor module to measure ambient illuminance of the electronic device, determine a visibility level of the electronic device based on the ambient illuminance of the electronic device, and display at least one augmented reality (AR) content corresponding to the selected target object on at least one of the main display or the sub-display based on the determined visibility level.

Abstract: A wearable electronic device includes: a display configured to provide visual information to a user; a lens frame including: a first frame, and a second frame. The first frame and the second frame surrounds at least a portion of the display, the second frame being coupled to the first frame to form an internal space of the electronic device. The wearable electronic device further includes a wearing member coupled to at least one side of the lens frame; a flexible printed circuit board disposed within the internal space; and a reinforcing member configured to have a higher rigidity than the lens frame. The reinforcing member includes: a first portion disposed between the flexible printed circuit board and the lens frame, and a second portion extending from the first portion by a predetermined angle to form a bend.
