A windshield corrective optical system includes a motor vehicle having a windshield. A camera is positioned within an occupant compartment of the motor vehicle directed toward the windshield and receiving light rays passing through the windshield. A sensor is configured to receive the light rays. A corrective element is configured to allow passage of the light rays through the corrective element to the sensor. The corrective element corrects aberrations of the light rays induced by passing through the windshield prior to the light rays reaching the sensor.

A display system for a head mounted device (HMD) including a lens comprising a display area on the lens of the HMD, the lens having a base angle and a pantoscopic tilt, a display engine and optics, and a prism to redirect output from the optics to the display area on the lens of the HMD, accounting for the base angle and the pantoscopic tilt.

The present invention discloses a quantum-dot composite film comprising: a quantum-dot prism film, comprising a quantum-dot layer and a first plurality of prisms disposed over the quantum-dot layer, wherein a first optical prism film and a second optical prism film are disposed over the quantum-dot prism film for increasing the brightness level of the quantum-dot prism film.

The present disclosure relates to a decoration member comprising a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer comprises a molybdenum-titanium oxide (Mo.sub.aTi.sub.bO.sub.x).

Foldable and folded light guide articles are described. Foldable light guide articles include a backing, a light guide disposed upon the backing and a prism disposed upon the backing adjacent to the light guide such that when the backing is folded about an axis between the prism and the light guide, a side of the prism is positioned adjacent to and aligned with an end of the light guide. Folded light guide articles include a light guide, a first prism and a second prism. The first prism is disposed adjacent to and aligned with an end of the light guide. The second prism is disposed adjacent to and aligned with the first prism with a low-index material separating the first prism and the second prism.

This structure includes a transparent member. The transparent member has a first surface and a second surface arranged to face each other, and allows light entering from the first surface to propagate toward the second surface by reflection. The transparent member has a plurality of slopes inclined with respect to the first surface, in an optical path between the first surface and the second surface.

Presently described are optical stacks comprising a first optical film comprising a plurality of structures comprising an optically active portion designed primarily to provide optical gain and optionally an optically in-active bonding portion disposed on a first surface bonded to a second optical film with a light-transmissive adhesive layer such that a portion of the structures penetrate the adhesive layer and a separation is provided between the adhesive layer and the first surface. In one embodiment, the optical stacks exhibit a combination of high peel strength and high retained brightness, particularly after aging. The adhesive layer preferably comprises an interpenetrating network of the reaction product of a polyacrylate component and a polymerizable monomer and the adhesive layer has an elastic modulus ranging from 100 to 2000 MPa at 25° C.

A wearable display device according to an embodiment may comprise: a first prism, positioned in front of a user's eye, for controlling the path of an incident light and enabling the arrival of a virtual image to be displayed on the eye; a second prism, coupled to the first prism, for reducing distortion of a real image arriving at the user's eye; and a coating layer which is interposed between the first prism and the second prism and of which the brightness is controlled in inverse proportion to the ambient brightness, such that the visibility of the virtual image increases.

A HUD system and light source apparatus can be manufactured with miniaturization at low cost. A head-up display apparatus includes: an image display apparatus generating image light to be projected; an optical system performing predetermined correction to the image light emitted from the image display apparatus; and a concave mirror reflecting the image light corrected by the optical system to project it onto a windshield or combiner. The image display apparatus includes: a solid light source; a collimating optical system converting, into parallel light, the light from the solid light source; a lighting optical system configured by an optical member that polarizes a direction of a light beam generated by the collimating optical system and simultaneously expands a width of the light beam; and a display apparatus, the image display apparatus being configured to be arranged across and opposite the optical system on an optical axis of the concave mirror.
