See-through Transparent Displays
ABSTRACT: The ideal see-through display would be one that preserves situational awareness by offering a panoramic view of the surroundings with overlaid high-resolution color imagery. Such a system should also be unobtrusive; that is, compact, light-weight, and comfortable, where comfort comes from having an adequate exit pupil, generous eye relief, ergonomic center of mass, and focus at infinity. Conventional refractive optics cannot satisfy this suite of demanding requirements. Even after years of highly competitive development, head-mounted displays (HMDs) exhibit limited field of view and are anything but compact, light-weight, and comfortable. SGB Labs is pleased to announce that it has proven the feasibility a game-changing solution to this challenging problem by successfully demonstrating an ultra-wide field-of-view see-through display. Significantly, the pixel count can be scaled to support Snellen 20/20 visual acuity over the field of view. Although to date only monochrome displays have been demonstrated, the methodology has matured to the point where the added complexity associated with introducing additional wavelengths can finally be addressed. That is, having overcome the technical barriers of limited field of view and limited pixel resolution, the goal of the proposed Phase-I program is to demonstrate the feasibility of extending our technology to embrace full color. BENEFIT: A see-through display focused at infinity must satisfy a suite of very challenging requirements; including wide field of view, high resolution, full color, good luminance, adequate dynamic grayscale, and minimal power consumption. To date, no waveguide technology has been able to satisfy these critical requirements, the most important being wide field of view. SBG Labs"technology enables the first waveguide-based display with the ability to meet all requirements. The benefit to the warfighter will be vastly improved situational awareness and comfort. The technology is especially suitable for applications involving augmented reality and virtual reality. A wide-field-of-view see-through display is a dual-use product. SBG Labs hopes to leverage the proposed development into OEM components for consumer HMDs. The channel to market will be the same as SBG Labs"other products: major consumer electronics companies. In the short term, since military devices will support a higher price point than commercial ones and entail lower production volumes, having the DoD as its first customer will enable SBG Labs to gradually ramp up its manufacturing infrastructure and engineer out the cost. In the long term, commercial demand will far outstrip defense demand, driving down cost to the DoD and spurring further technical development.
