摘要： A head mounted display including a first display, a second display, a third display, and an optical element is provided. The first display projects a first image to a first target area. The second display projects a second image to a second target area. The third display projects a third image. The optical element is disposed among the first target area, the second target area, the first display, the second display, and the third display. The optical element transmits the first image to the first target area and the second image to the second target area, and reflects the third image toward the first target area and the second target area.

摘要： The present disclosure relates to an image display apparatus with an extended depth of focus (DOF) and a method of controlling the same. The image display apparatus with an extended DOF includes a display unit, an optical element unit disposed to be spaced apart from a front surface of the display unit by a predetermined distance (Dmd) and including a lens and a pinhole that has an opening portion (PDml), a main optics lens disposed to be spaced apart from a front surface of the optical element unit by a predetermined distance (Do) and configured to form a convergence area of a virtual image on a pupil of an eye of a user, and a control unit that performs a control for extending a DOF with respect to the virtual image provided to the user.

摘要： Some embodiments are directed to a display apparatus for enabling a user to experience a 3D perception when visual information is presented by the display apparatus. The display apparatus has an image forming unit having a two-dimensional array of image subpixels arranged to emit light for presenting associated visual information, and an optical system having an array of diffractive optical elements associated with respective ones of the array of image subpixels. Each diffractive optical element is arranged to diffract light from the associated image subpixel into a diffraction pattern with a plurality of diffraction orders to provide the visual information from the associated image subpixel to a plurality of directional viewing regions associated with the plurality of diffraction orders.

摘要： An optical system includes a reflective surface, a display adapted to emit image light toward the reflective surface, and a multilayer reflective polarizer disposed proximate the reflective surface. The multilayer reflective polarizer is curved about two orthogonal axes and includes at least one layer that is substantially optically uniaxial at at least one location. The image light is transmitted by the multilayer reflective polarizer after it is first reflected by the multilayer reflective polarizer. A head-mounted display includes a first optical system and a second optical system disposed proximate the first optical system.

摘要： Optical systems including an image surface and an exit surface are described. First second and third optical lenses, a partial reflector, a multilayer reflective polarizer and a retarder are disposed between the image surface and the exit surface. At least one location on at least one layer of the multilayer reflective polarizer is substantially uniaxially oriented. Each chief light ray that passes from the image surface to the exit surface is incident on the multilayer reflective polarizer with an angle of incidence less than about 30 degrees. The optical system may include a plurality of major surfaces disposed between the image surface and the exit surface where each major surface is convex toward the image surface and where at least six different major surfaces have six different convexities.

摘要： It is provided a method for viewing an image that is wider or higher than the display screen, wherein, the image is evenly divided into two portions by using a line passing through centers of larger edges of the image compared to the display screen. The method comprises, at the side of shutter glasses, the steps of receiving a message indicating display of a first portion of the two portions; turning dark of the shutter glasses and turning refraction direction of the shutter glasses towards a first position; turning transparent of the shutter glasses; receiving a message indicating display of a second portion of the two portions; turning dark of the shutter glasses and turning refraction direction of the shutter glasses towards a second position; and turning transparent of the shutter glasses.

摘要： Optical devices based on novel components for selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the previous (parent) patents are herein made both more useful in practical day-to-day use and more widely applicable to improving the ability of a user to perceive visual stimuli.
