Images perceived to be substantially full color or multi-colored may be formed using component color images that are distributed in unequal numbers across a plurality of depth planes. The distribution of component color images across the depth planes may vary based on color. In some embodiments, a display system includes a stack of waveguides that each output light of a particular color, with some colors having fewer numbers of associated waveguides than other colors. The stack of waveguides may include by multiple pluralities (e.g., first and second pluralities) of waveguides, each configured to produce an image by outputting light corresponding to a particular color. The total number of waveguides in the second plurality of waveguides is less than the total number of waveguides in the first plurality of waveguides, and may be more than the total number of waveguides in a third plurality of waveguides, in embodiments where three component colors are utilized.

A head mounted display, according to various embodiments of the present disclosure, comprises: a housing comprising an opening part; an lens assembly arranged in the opening part; and a light shielding part arranged along the circumference of the opening part, wherein the light shielding part may be in a first configuration of being drawn out from the housing via the opening part so as to enable being worn on the face of a user, and a second configuration of having at least one portion thereof inserted into the housing via the opening part.

There is provided a head mounted display including: an optical system comprising: right-eye and left-eye optical systems that guide a real image light and right-eye and left-eye virtual image lights; and an optical element comprising: first polarization plates disposed at emission sides of the right-eye and left-eye optical systems; wherein the right-eye virtual image light from the right-eye optical system and the left-eye virtual image light from the left-eye optical system are blocked by the first polarization plate at the emission side of the left-eye optical system and by that of the right-eye optical system respectively; and at least one of: first wave plates disposed at the emission sides of the right-eye and left-eye optical systems so that the real image light from the right-eye and left-eye optical systems passes therethrough; and second wave plates disposed at incident sides of the right-eye and left-eye optical systems.

An example wearable electronic device may include a housing including a first rim housing and a second rim housing coupled to form at least one opening; at least one bracket including a first surface facing the first rim housing and a second surface facing the second rim housing and disposed in a first space between the first rim housing and the second rim housing; at least one wave guide overlapped with the at least one opening and disposed to be at least partially supported by the at least one bracket; at least one display module disposed in a second space adjacent to the first space between the first rim housing and the second rim housing and disposed to face the at least one wave guide through the at least one bracket; a first sealing member disposed between the at least one bracket and the first rim housing; and a second sealing member disposed between the at least one bracket and the second rim housing.

A wearable electronic device is provided. The wearable electronic device includes a display, a first transparent member including a first surface facing a user's right eye and a second surface facing away from the first surface, a second transparent member including a third surface disposed to face the user's left eye, and a fourth surface facing away from the third surface, and a processor configured to output a first image by using a first region of the display or output a second image by using a second region different from the first region, wherein the first transparent member receives the first image and provides the first image to the user's right eye, and the second transparent member receives the second image and provides the second image to the user's left eye.
