Abstract: A three-dimensional (3D) image display device includes a display device; a variable focus optical system configured to focus the 3D image formed by the display device on a reference plane, a processor configured to determine a representative depth value of the 3D image by selecting a depth position, from among a plurality of depth positions corresponding to the 3D image, as the representative depth value, and control the variable focus optical system to adjust the reference plane by adjusting a focal point of the variable focus optical system based on the representative depth value; and a transfer optical system configured to transfer the 3D image focused on the reference plane to a pupil of an observer.

Abstract: Provided are display apparatuses and electronic apparatuses that include the display apparatuses. The display apparatus may include an optical system that transfers a first image and a second image to an ocular organ of a user. The optical system may include at least two polarization-dependent lenses. Each of the two polarization-dependent lenses may have a focal length that varies based on a polarization state of incident light. The two polarization-dependent lenses may have optically different characteristics with respect to the first and second images. The display apparatus may further include at least one wave plate and/or at least one polarizer provided between the two polarization-dependent lenses or outside thereof.

Abstract: A see-through type display apparatus includes a spatial light modulator configured to time-sequentially output a multi-layered two-dimensional (2D) image, a depth generator configured to generate a multi-layered depth image having pieces of different depth information from the multi-layered 2D image based on a focal distance that is a distance between the depth generator and a focus point of the multi-layered 2D image; and a light path change member configured to change at least one of a first transmission path of light corresponding to the multi-layered depth image and a second transmission path of external light corresponding to an external image, to thereby transmit the multi-layered depth image and the external image to a same area.
