    Abstract: A geometric phase optical element and a three-dimensional display apparatus including the same are provided. The geometric phase optical element includes: a liquid crystal layer; a first electrode on a surface of the liquid crystal layer; and a second electrode on another surface of the liquid crystal layer, wherein, when no voltage is applied to the first and second electrodes, the liquid crystal layer is configured such that a phase difference according to an arrangement of the liquid crystal is π and light transmitted through the liquid crystal layer is diffracted by a first deflection angle, and when a first voltage that causes the phase difference according to the arrangement of the liquid crystal to become π/2 is applied to the first and second electrodes, the liquid crystal layer is configured such that the light transmitted through the liquid crystal layer is diffracted by a second deflection angle.

    Abstract: Provided is a display apparatus including a vision correction lens. The display apparatus may include: an image forming device configured to form a virtual image; a vision correction lens configured to correct eyesight of a viewer; a combiner configured to mix the virtual image with light containing an outside landscape and having passed through the vision correction lens and provide the viewer with the virtual image and the light that are mixed with each other; and a virtual image positioner configured to adjust, according to a state of eyes of the viewer, a depth of a virtual image plane at which the virtual image is viewed, wherein the combiner may be arranged between the vision correction lens and the eyes of the viewer.

    Abstract: A method of correcting image latency in implementing augmented reality includes receiving a first image including frames, in which a time point and a pose of an electronic apparatus for each frame are recorded, from an external apparatus; rendering the first image; receiving first data corresponding to a first time point of a first frame; receiving second data corresponding to a second time point of a second frame; calculating a respective pose of the electronic apparatus for each scan line of a second image based on the first data and the second data; calculating a pixel shift for each pixel in each scan line based on the respective pose calculated for each scan line; generating the second image by correcting the first image based on the pixel shift; and transmitting the second image to the external apparatus.
