Abstract: An electronic device is provided. The electronic device according to the present disclosure includes an optical system for generating light to implement an image and a display part for emitting the light provided from the optical system. The optical system includes an image source panel, a first projection lens for projecting light provided from the image source panel onto the display part, a second projection lens for projecting the light provided from the image source panel to the display part, wherein the second projection lens has a angle of view wider than a angle of view of the first projection lens, and a position changing part for switching positions of the first projection lens and the second projection lens to selectively match the first projection lens and the second projection lens to a path of the light provided from the image source panel. The electronic device of the present disclosure may be associated with an artificial intelligence module, a robot, an augmented reality (AR) device, a virtual reality (VR) device, a device related to a 5G service, and the like.

Abstract: Disclosed is an electronic device. An electronic device according to the present invention includes: a main frame having a first opening; a display unit connected to the main frame and having a display area which may be exposed through the first opening; and a virtual reality frame movably coupled to the main frame and having a second opening to which a first lens is coupled, in which when the virtual reality frame moves to a first location where the first opening and the second opening are arranged side by side in a sight direction of a user, the user is capable of recognizing an image of the display unit as a virtual reality image through the first lens, and when the virtual reality frame moves to a second location deviated from the first location, the user is capable of recognizing the image of the display unit as an augmented reality image. An electronic device according to the present invention may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.
