摘要： A head mounted image display includes a display body having image display sections and optical systems and a supporting section for fixing the display body in front of the eyes of an observer so that the observer can view the image display sections with his eyes. The supporting section has at least four supporting points, which are arranged so that at least one supporting point is placed outside a plane formed by at least three supporting points. Thus, the observer can comfortably wear the display.

摘要： A circuit device includes a storing section configured to store a rendering image and a warp processing section. The warp processing section includes a coordinate converting section, a coordinate-address converting section, and an output section. The coordinate converting section converts, with coordinate conversion based on warp parameters and rotation correction parameters, an output coordinate, which is a coordinate on a display image, into an input coordinate, which is a coordinate on the rendering image. The coordinate-address converting section converts the input coordinate into a read address of the storing section. The output section reads out pixel data of the rendering image from the read address of the storing section and outputs, based on the read-out pixel data, pixel data in the output coordinate of the display image.

摘要： The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.

摘要： A backlit display device includes a plurality of light sources, a plurality of tapered cups laid out in an array, a diffuser, a display module displaying an image, and an image concave mirror being positioned along an optical path sequentially. Each tapered cup is tilted at a different angle and corresponded to one light source respectively to define an emitting angle of each light source. The light of the light sources passes through the diffuser forming a backlight. The display module and the backlight are positioned within and outside the focus of the image concave mirror respectively. The backlight illuminates the image forming an image light and the image light is reflected by the image concave mirror and then projected to a single eye box. Each light source illuminates a portion of the display module. A central normal of each tapered cup intersects the center of the single eye box.

摘要： A wearable optical assembly includes a transparent optical element and a set of multiple light-emitting elements positioned on or within the optical element. The optical assembly positions the optical element in a sight line of a user wearing the optical assembly. Each light-emitting element includes one or more inorganic microLEDs that generate and emit infrared output light to propagate out-of-plane away from the optical element toward an eye or face of the user wearing the optical assembly. Each light-emitting element of the set is sufficiently small in at least one transverse dimension, and the light-emitting elements occupy a sufficiently small fraction of an areal extent of the set, so as to enable visual observation of a scene, by the user wearing the optical assembly, through the optical element along the sight line of the user, the sight line passing through the set of light-emitting elements.

摘要： A projection display device includes an imaging unit; a planar waveguide with a light decoupling face for a light beam bundle produced by the imaging unit; an at least partially transparent reflection plate arranged in the field of view of a user and configured to reflect a light beam bundle decoupled from the waveguide to an eyebox predetermined for the user's eyes; an eye-tracking device configured to determine an eyebox window which is currently occupied by the user's eyes; and a dynamic scattered light absorber, which, to shadow the light decoupling face in a surface portion which is dynamically adjustable depending on a signal of the eye-tracking device and which extends starting from at least one of the edges of the light decoupling surface, is configured to at least partially limit the decoupled light beam bundle to the current eyebox window.

摘要： A display device includes light sources that emit light, a display panel that displays an image, and a light guide panel that guides the light emitted from the light sources to the display panel. The light guide panel includes an incident surface facing the light sources, an emission surface facing the display panel, a first reflective surface facing the incident surface, and a second reflective surface facing the emission surface. The first reflective surface has a concave shape that reflects light so that the reflected light becomes closer to parallel light when viewed in a facing direction of the display panel and the light guide panel in the light guide panel, is tilted at an angle larger than 0 degrees with respect to the incident surface, and intersects the second reflective surface at an angle smaller than 90 degrees.
