Abstract: A light emitting diode package for a directional display may comprise light emitting diodes and a protection diode. The protection diode may be arranged in a well that is at a different location to the well that the light emitting diodes are arranged. The directional display may include a waveguide. The waveguide may include light extraction features arranged to direct light from an array of light sources by total internal reflection to an array of viewing windows and a reflector arranged to direct light from the waveguide by transmission through extraction features of the waveguide to the same array of viewing windows. The brightness of the directional display can be increased. An efficient and bright directional display system can be achieved. Efficient light baffling for light escaping from the edge of the waveguide is achieved through light deflecting extraction films.

Abstract: Teleconferencing is performed between two telecommunication devices having a display device and a stereoscopic pair of cameras positioned outside opposed sides of the display device at the same level partway along those sides. The separation between the centers of the cameras is in a range having a lower limit of 60 mm and an upper limit of 110 mm to improve the perceived roundness in a displayed stereoscopic image of a head. In captured stereo images that are video images, a head is segmented and the segmented backgrounds are replaced by replacement images that have a lower degree of perceived stereoscopic depth to compensate for non-linear depth perception in the displayed stereo images. Images are shifted vertically to position an eye-line of a detected face at the level of the stereoscopic pair of cameras of the telecommunication device where the images are displayed, improving the naturalness of the displayed image.

Abstract: A method for demultiplexing frames of compressed image data is provided. The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.

Abstract: A method of mounting screen material may include a screen mounted to a frame at multiple mounting points. One embodiment may include mounting patches attached along the perimeter of the screen. These mounting patches may be strain relieved in order to enable rolling the screen without sacrificing the in-plane rigidity of the patches when the screen is mounted to a frame. Stated differently, the strain relieved patches may reduce the strain on the screen in the circumstance the screen is rolled onto a core. The mounting patches may be strain relieved by locating notches or slits in the mounting patch.

Abstract: The PCS may include a polarizing beam splitter, a polarization rotating element, a reflecting element, and a polarization switch. Typically, a projector outputs randomly-polarized light. This light is input to the PCS, in which the PCS separates p-polarized light and s-polarized light at the polarizing beam splitter. P-polarized light is directed toward the polarization switch on a first path. The s-polarized light is passed on a second path through the polarization rotating element (e.g., a half-wave plate), thereby transforming it to p-polarized light. A reflecting element directs the transformed polarized light (now p-polarized) along the second path toward the polarization switch. The first and second light paths are ultimately directed toward a projection screen to collectively form a brighter screen image in cinematic applications utilizing polarized light for three-dimensional viewing.

Abstract: A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermore, the stiffening strip may enable the use of screen vibration techniques to reduce speckle in display applications that use projection screens, particularly those display applications using illumination sources prone to speckle such as laser-based projection. The screen vibration may be provided by a vibrating device attached to the stiffening strip.

Abstract: A controller that may implement variation of the content of binocular images which may depend upon which region of a binocular image a viewer is fixating. An aspect of the present disclosure may include locally controlling the viewer's perceived depth impression which may depend on where in perceived depth in an image the viewer is fixating. This may enable the perceived depth to be optimized across the image for quality and performance reasons.
