  • Patent number: 10416453
    Abstract: A head mounted display (HMD) for viewing a virtual environment generally include a flat display (FD), lenses for focusing on the FD, and a housing to enclose the FD and lenses. The housing is generally opaque to block out all external light, so the viewer only sees light from the FD. By making a portion or all of the housing translucent or transparent, ambient light and other external light can be seen by the viewer, providing additional visual cues and a larger perceived field of view. Additionally, other people can see light from the FD. The lenses are configured to view the FD and parts of the translucent housing.

  • Patent number: 10129533
    Abstract: A three dimensional (3D) stereoscopic image rendering system uses a lenticular lens sheet with a light diffusing multi-layer, which may include an adhesive layer, formed on the external surface of its lower base. The microstructural constitution of the light diffusing multi-layer suppresses moiré patterns typically affecting the 3D images. When longitudinally directed stray light rays are internally reflected from the interior surfaces of each lenticular lens in the sheet and impinge on the light diffusing multi-layer contacting the lower base, the stray light rays are scattered diffusely into various directions, thereby significantly reducing the intensity of the moiré pattern and its effect on the image. In addition, certain related problems, such as crosstalk between left and right directed images are also reduced. As a result, the viewer perceives a high quality, moiré free, stereoscopic 3D image.

  • Patent number: 10031396
    Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a polymer dispersed liquid crystal lens doublet using a PDLC layer. The doublet is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The refractive index of the lens doublet is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the lens doublet.

  • Patent number: 10003789
    Abstract: Our inventive method enables stereoscopic 3D displays to be watched by 3D and 2D viewers simultaneously. Ghosted images observed on traditional 3D displays can be eliminated for viewers without stereoscopic glasses while 3D perception is preserved for viewers with glasses. A preferred method for displaying an image on a 3D+2D television comprises displaying a composite image (“L+wN”), comprising a left (“L”) image and a weighted image (“wN”), for a first period of time; and displaying a right (“R”) image for a second period of time. The display of “wN” partially cancels out the perception of “R” to mitigate ghosting for viewers not wearing 3D eyeglasses. In the illustrative embodiment, “wN” is a weighted negative version of “R”.

  • Patent number: 9964671
    Abstract: The present invention provides a display substrate including a plurality of pixel units. Wherein, the plurality of pixel units include a plurality of oblique pixel units, and length directions of the plurality of oblique pixel units are oblique relative to a horizontal direction. The present invention further provides a display panel and a stereoscopic display device. When stereoscopic display is performed using the display panel according to the present invention, the resolutions of each parallax image in both a length direction and a width direction of the display panel decrease, i.e., the problem that the resolution of a single-eye image decreasing only in one direction when stereoscopic display is performed is avoided, thereby improving the display effect.
