Abstract: A head-mounted computing device having a convertible waveguide optical engine assembly is disclosed. The waveguide in accordance with aspects herein can be utilized in its transparent configuration, or may be provided with means for blocking light from passing through it either by using mechanical means, or by using different types of treatments that can switch the waveguide between opaque and transparent states based on an external stimulus, such as, for example, electricity, temperature, light, and the like. Further, the waveguide optical engine assembly comprises a compact footprint, which is advantageous for head-mounted computing devices. In addition to the compact footprint of the waveguide optical assembly, the configuration of the waveguide optical assembly, as disclosed, allows for maximization of advantages provided by the waveguide as related to eye box and eye relief.

Abstract: A head-mounted computing device having a waveguide optical engine assembly is disclosed. The waveguide is enclosed in a housing to limit or minimize exposure of the waveguide to ambient light. Further, the waveguide optical engine assembly comprises a compact footprint by allowing the other components of the waveguide optical engine assembly, such as a microprojector, a prism assembly, and the like, to be placed behind a rear surface of the waveguide. In addition to the compact footprint of the waveguide optical assembly, the configuration of the waveguide optical assembly disclosed, allows for maximization of advantages provided by the waveguide as related to eye box and eye relief. Additionally, the power requirements of the waveguide are greatly reduced, which also results in a prolonged battery life powering the head-mounted computing device.

Abstract: A head-mounted display system displays information via a matrix display element mounted within a housing that is positioned relative to at least eye of a user. The display is connected to a video or information source such that the user can view information or images shown on the display. The display can be mounted to a frame so that the user can move the display in and out of the user's field of view without adjusting the supporting harness that holds the display on the user's head.

Abstract: The invention relates to a microdisplay system that utilizes a small high resolution active matrix liquid crystal display with an illumination system and a magnifying optical system to provide a hand held communication display device. The system can employ an LED illumination system and cellular communication or processor circuits within a compact housing to provide communication devices such as pagers, telephones, televisions, and hand held computer devices with a compact high resolution video display.

Abstract: A binocular display device can include first and second display assemblies. A rail system can adjustably support the first and second display assemblies. The rail system can have a first rail slidably secured to a front region of the display assemblies, and second rail slidably secured to a rear region of the display assemblies. One rail can be at an upper region and the other rail can be at a lower region. Each display assembly can be slidably mounted to one rail along a bearing length L1 and to the other rail along a bearing length L2 that is less than the bearing length L1. A release/locking system can be included for releasing the display assemblies relative to the rail system to allow the position of the display assemblies relative to each other on the rail system to be adjusted, and for locking the display assemblies at a desired position.

Abstract: A head mounting viewing system includes a viewer having a microdisplay for displaying images. Viewing optics can be included for viewing the display. The display and the optics can be housed in a housing. Integrated operational controls can be located on the housing for controlling the operation of the viewer.

Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system. The image is written to the the display therein causing the liquid crystal to move to a specific image position. A light source is flashed to illuminate the display. The pixel electrodes are set to a specific value to cause the liquid crystal to move towards a desired position. The process of writing, flashing, and setting the electrode intensity value to reorient the liquid crystal to produce an image is repeated.

Abstract: A binocular display device or module includes a pair of display panels that are custom aligned with respective viewing optics. The binocular display device has a first lens assembly for viewing the first display panel and a second lens assembly for viewing the second display panel. Alignment fixtures within the binocular display device are used to physically align and fix the optics with the display panels using an alignment system. The alignment system includes a camera system for viewing the first display panel of the binocular display device through the first lens assembly, and the second display panel through the second lens assembly. Display panel alignment indicia can be located on the first and second display panels. A viewing screen system can be included for viewing images of the display panel alignment indicia on the first and second display panels which are provided by the camera system.
