    Abstract: A light guide device that does not cause non-uniformity in image light and external light and does not cause ghosts, and a virtual image display apparatus provided with the light guide device. The light guide device includes a parallel light guide, an incident section, and an emission section. Here, the light guide device is set such that image light rays are reflected without reflecting from a boundary surface between the parallel light guide and the reflection unit and head for an observer. Thus, the image light rays only pass through half mirrors, which are positioned in positions where the image light rays are emitted from the reflection unit of the emission section or are positioned therearound. Accordingly, it is possible to prevent luminance non-uniformity or light reduction by reducing the number of times of the image light rays to be observed pass through the half mirrors.

    Abstract: During the manufacturing of the light guide device, the first and second bonding ribs are used such that the light guide prism and the opposing prism are connected with each other from a specific offset direction. In this case, a difference between sizes of clearances between the first bonding surface and the second bonding surface caused by a difference in inclination angles of the offset direction with respect to the first bonding surface is used such that a flow direction of the adhesive is controlled and filling is performed in a desire state, and thus high accuracy of the joint formed by the adhesive is maintained.

    Abstract: According to one embodiment, a display device (100) includes a light emitter (115) and a reflector (130). The light emitter (115) emits light including image information. The reflector (130) has a plurality of reflective surfaces (133) arranged in a first direction. The reflective surfaces (133) reflect a portion of the light. A length in a second direction of one of the reflective surfaces (133) is longer than a length in the first direction of the one of the reflective surfaces (133). The second direction intersects the first direction. A first plane is tilted with respect to a second plane. The first plane includes an incident direction of the light at the reflector (130) and a reflection direction of the light at the reflector (130). The second plane includes the first direction and the second direction. The second direction is tilted with respect to an intersection line between the first plane and the second plane.

    Abstract: The present invention provides a projection system (10), preferably for a head-up display e.g. on board a vehicle, comprising a laser source (1), a diffuser (3) and telecentric optics (2) disposed between the laser and the diffuser so that the telecentric optics outputs parallel rays to the diffuser, the diffused light being thus independent from the incidence angle; each pixel of the projected image has the same brightness, regardless of the angle or of the position from which it is viewed.

    Abstract: This invention concerns an ergonomic optical see-through head mounted display device with an eyeglass appearance. The see-through head-mounted display device consists of a transparent, freeform waveguide prism for viewing a displayed virtual image, a see-through compensation lens for enabling proper viewing of a real-world scene when combined together with the prism, and a miniature image display unit for supplying display content. The freeform waveguide prism, containing multiple freeform refractive and reflective surfaces, guides light originated from the miniature display unit toward a user's pupil and enables a user to view a magnified image of the displayed content. A see-through compensation lens, containing multiple freeform refractive surfaces, enables proper viewing of the surrounding environment, through the combined waveguide and lens. The waveguide prism and the see-through compensation lens are properly designed to ergonomically fit human heads enabling a wraparound design of a lightweight, compact, and see-through display system.
