A light control apparatus, a passive light-emitting image source and a head-up display system are provided. The head-up display system includes a light source, a collimator element, a light concentrator element, a diffuser element, a liquid crystal panel and a transflective reflection device for displaying; the collimator element is configured to adjust an exit direction of light emitted by the light source into a preset angle range; the light concentrator element is configured to concentrate the light emitted by the light source; the diffuser element is configured to diffuse the light emitted by the light source; the liquid crystal panel is configured to convert the light emitted by the light source into imaging light, and allow the imaging light to be incident on the reflection device for displaying; and the reflection device for displaying is configured to reflect the imaging light to a preset region.

A sidewall assembly for an aircraft and an aircraft are provided. In one example, the sidewall assembly includes a window. A sidewall portion has an inner-facing side and at least partially surrounds the window. A transparent display panel is coupled to the sidewall portion and covers the inner-facing side of the sidewall portion including the window. The transparent display panel includes a display screen configured to display information to a passenger. A display controller is in communication with the transparent display panel to communicate a video/audio signal providing the information to the display screen.

An object is to provide a projection image displaying member that enables display of a projection image using p-polarized light and can provide a head-up display system having high polarizing sunglasses suitability, a windshield, and a head-up display system. The object is achieved by a projection image displaying member having a transparent substrate having an in-plane retardation of 5000 nm or more and at least one selective reflection layer, wherein the selective reflection layer is located closer to the side on which projection light is incident than the transparent substrate is.

A virtual image display device includes a polarization adjustment member that includes a polarizing plate and a support plate. The polarizing plate has a property of blocking a light which is oscillated in an axial direction of a block axis while the polarizing plate is in a state where a residual stress, a degree of which is maximized in a first residual stress direction along a plane of the polarizing plate, is left in the polarizing plate. The support plate supports the polarizing plate while the support plate is in a state where a residual stress, a degree of which is maximized in a second residual stress direction along a plane of the support plate, is left in the support plate. The polarizing plate and the support plate are bonded together such that the first residual stress direction is along the second residual stress direction.

A display device (e.g., in a contact lens) is mounted on the eye. The eye mounted display contains multiple sub-displays, each of which projects light to different retinal positions within a portion of the retina corresponding to the sub-display. Additionally, a “locally uniform resolution” mapping may be used to model the variable resolution of the eye. Accordingly, various aspects of the display device may be based on the locally uniform resolution mapping. For example, the light emitted from the sub-displays may be based on the locally uniform resolution mapping.

A surgical navigation system includes: a tracker (125) for real-time tracking of a position and orientation of a robot arm (191); a source of a patient anatomical data (163) and a robot arm virtual image (166); a surgical navigation image generator (131) generating a surgical navigation image (142A) including the patient anatomy (163) and the robot arm virtual image (166) in accordance to the current position and/or orientation data provided by the tracker (125); a 3D display system (140) showing the surgical navigation image (142A).

A virtual image display device includes a projection optical system that projects an image display light toward a virtual image presentation plate. The projection optical system includes a first concave mirror that reflects the image display light toward the virtual image presentation plate and a second concave mirror that reflects the image display light toward the first concave mirror. Defining a reference plane along both a direction of incidence and a direction of output of the image display light on the virtual image presentation, the first concave mirror is oriented such that the image display light is incident on the first concave mirror in a direction along the reference plane, and the second concave mirror is oriented such that the image display light is incident on the second concave mirror in a direction intersecting the reference plane.

A device for generating a virtual image with stray light suppression comprises at least one light source for producing light with a specified wavelength, a display element for producing an image, and an optical waveguide for expanding an exit pupil. An aperture mask that has holes and non-transparent regions is arranged above an upper boundary surface of the optical waveguide.

A head-up display system of a vehicle visually transmits information to eyes of an occupant. The head-up display system comprises an illumination device configured to emit a display light and a windshield spaced from the illumination device and extending transverse to the display light. The head-up display system comprises a holographic panel coupled to and extending with the windshield and arranged to diffract the display light toward the eyes of the occupant. The display light emits toward the holographic panel in an entrance direction at an entrance angle relative to an axis normal to the holographic panel and diffracts away from the holographic panel in an exit direction at an exit angle relative to the axis, which is different than the entrance angle.

Laminated glass for a vehicle front window includes a curved first glass plate having a trapezoidal or rectangular shape; a second glass plate having the same shape as the first glass plate; and an intermediate film disposed between the first and second glass plates.

An imaging section of an image projected from an imaging device incorporated in a dash board on a driver's seat side is included in an indoor side surface of the laminated glass in a state in which the laminated glass is incorporated in a vehicle body.

The intermediate film is provided with a wedge angle profile in a longitudinal direction and a horizontal direction of the laminated glass, and a thickness based on the wedge angle profile of the intermediate film based on the wedge angle profile continuously decreases from an upper side to a lower side and continuously decreases in a direction from a driver's seat side to a passenger seat side.
