Embodiments of a glass laminate structure comprising a non-strengthened glass sheet, a strengthened glass sheet, and at least one polymer interlayer intermediate the external and internal glass sheets are disclosed. The strengthened glass sheet can have a thickness ranging from about 0.3 mm to about 1.5 mm, the non-strengthened glass sheet can have a thickness ranging from about 1.5 mm to about 3.0 mm, and the polymer interlayer can have a first edge with a first thickness and a second edge opposite the first edge with a second thickness greater than the first thickness. The glass laminate structures provide advantageous optical properties. The glass laminate structure can be employed to provide a transparent display screen that minimizes image offset between two images formed by two reflections at two surfaces of the strengthened internal glass sheet.

A test fixture (10) for heads-up windshields (12) wherein aspherical devices (26) compensate for complex curvatures and optical aberrations in a heads-up display surface (16) of the windshield. A movable test grid (20) adjusts the elevation of preferred camera settings and a pivotal mounting of the test grid (20) enhances ghost image reduction and improves camera image resolution. A filter (36) limits interference of secondary ghost images (caused by IR coatings) with compliance assessment of the windshield.

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.

A display system, a mobile object, and an optical element. The display system includes an optical device through which light diverges, a light deflector configured to scan a light emitted from a light source in a main scanning direction and a sub-scanning direction orthogonal to the main scanning direction to form an intermediate image on the optical device, and an imaging optical system configured to project diverging light diverging through the optical device to form an image. An effective diameter a of a mirror of the light deflector for the intermediate image and a ratio c of a size of an image formed by the imaging optical system to the effective diameter a satisfy a condition in an equation given below.

The mobile object includes the display system, and the reflector is a front windshield. The optical element is used for the display system.

A variety of femtoprojector optical systems are described. Each of them can be made small enough to fit in a contact lens using plastic injection molding, diamond turning, photolithography and etching, or other techniques. Most, but not all, of the systems include a solid cylindrical transparent substrate with a curved primary mirror formed on one end and a secondary mirror formed on the other end. Any of the designs may use light blocking, light-redirecting, absorbing coatings or other types of baffle structures as needed to reduce stray light.

An apparatus includes a first support to fixedly support a wearable device comprising a substantially transparent display screen, a second support physically coupled to the first support, the second support to support a camera lens in a substantially fixed relation to the display screen, and an interface physically coupled to the first support and to the second support, the interface to removably attach the apparatus to a camera support system.

A display device includes an image forming unit, a projection unit, a main body, and a position correcting unit. The image forming unit includes a display surface and forms an image on the display surface. The projection unit projects a virtual image corresponding to an image on a target space by using output light from the image forming unit. The main body is equipped with an image forming unit and a projection unit. The position correcting unit changes a display position of a virtual image relative to the main body on the basis of an orientation signal representing an orientation of the main body. The position correcting unit includes a plurality of correcting units that change a display position of a virtual image by using different means. The position correcting unit selects at least one correcting unit from a plurality of correcting units in accordance with a frequency component of an orientation signal, and causes the selected correcting unit to change a display position of a virtual image.

A head-up display system for representing image information for an observer includes an image encoder for emitting a first image, a projection area including a portion of a composite pane for deflecting a projection of an image, wherein a calibration system is arranged to ascertain a deviation between a first image and the projection of the first image and has a capturing system arranged to capture reflection properties of the composite pane and the image encoder is arranged to generate a correction image as a function of the deviation.

A display apparatus for displaying an image includes a semitransparent carrier element, and a film provided on the semitransparent carrier element for at least regionally displaying the image. The film incorporates electrical components of the display apparatus. Further, the display apparatus can be included in a motor vehicle.

A motor vehicle includes a head up display projector producing a light field based upon image data such that the light field is reflected off of a windshield of the motor vehicle and is then visible to a driver of the motor vehicle as a virtual image. First means determines locations of physical objects visible to the driver through the windshield. Second means determines locations of eyes of the driver. An electronic processor receives first data indicative of the determined locations of the physical objects, and receives second data indicative of the determined locations of the eyes of the driver. The electronic processor produces the image data dependent upon the first data and the second data such that a symbol in the virtual image appears to be in a predetermined position relative to a selected one of the physical objects.
