Abstract:
A heads-up display system is configured for use in a motor vehicle. The system includes a standard vehicle window 22 (i.e. no special coatings), an optical image projector 14, and a vehicle dashboard 15 equipped with a faceted reflective surface 18. The optical image projector is configured to project an image onto the faceted reflective surface. The faceted reflective surface is configured to reflect the image from the optical image projector onto a window surface of the standard vehicle window. The window surface is oriented to reflect the image from the faceted reflective surface toward an occupant 26. The faceted reflective surface may be disposed within a plurality of troughs separated by a plurality of diffuse reflecting partitions. The plurality of troughs may be configured to shield the occupant from extraneous reflections. The faceted reflective surface may include a plurality of electrically controlled facets. The plurality of electrically controlled reflective facets may be an array of electrowetting cells.
Abstract:
A contoured display (10) that includes a faceplate (20) configured to propagate an image in a collimated manner from an interface surface (30) of the faceplate (20) configured to receive the image from a display (10) device to a display surface (14) of the faceplate (20). The display surface (14) is contoured to provide a three-dimensional (3D) contoured surface that provides designers with artistic freedom when designing a display (10) shape, and a convenient way to contour a display surface (14) to reduce the effects of glare on the display surface (14).

Abstract:
A vehicle windshield display system (12) for detecting obstruction of a vehicle (10) operator (16)'s field of view (14) by a windshield display (18). The system (12) provides closed-loop feedback to perform a visual check of what is actually being displayed on a windshield display (18) in order to avoid obstructing an operator (16)'s field of view (14). The system (12) includes a windshield display (18) configured to be installed into a vehicle (10) and configured to display a graphic (20) in a field of view (14) of an operator (16) of the vehicle (10), a camera (22) configured to determine an image of the graphic (20) displayed by the windshield display (18), and a controller (28) configured to determine if the image indicates that field of view (14) is obstructed. The camera (22) is used to monitor the windshield display (18) and provide feedback to the controller (28) so that appropriate adjustments to the graphic (20) being displayed can be made.

Abstract:
A windshield display system (10) that includes a light source (20) such as a laser (30B) configured to project light from a plurality of source locations (22A, 22B, 22C, 22D, 22E) onto a desired location (18) of a windshield (12). The number of source locations (22A, 22B, 22C, 22D, 22E) and relative spacing apart of the source locations (22A, 22B, 22C, 22D, 22E) is such that light emitted from the source locations (22A, 22B, 22C, 22D, 22E) and reflected into an eye (28) of an operator (16) is characterized as having a reflected light power less than a power threshold necessary to fulfil a laser safety standard. A camera (52 aiming at the projection area may be used to align the plurality of light beams.
Abstract:
A windshield display system for installation into a vehicle that includes a windshield (16), a transparent display (18) overlaying the windshield (16), and an array (24) of electrowetting lenses (26A, 26B) overlaying the transparent display (18). Each lens of the array (24) is operable to a flat-state where light (28B) passes through the lens (26B) substantially undistorted, and a shaped-state where emitted light (28A) from an underlying portion (30) of the transparent display (18) is directed in order to increase an apparent brightness of the emitted light (28A). The array (24) selectively magnifies pixels or portions of the transparent display (18), while maintaining vision clarity for the operator in regions of the windshield (16) where images are not being displayed. The array (24) may also outline or highlight images being displayed with a region of distortion of surrounding the image to distort the view of the scene outside the vehicle to help the operator discern the image when the outside lighting conditions are less than ideal.
Abstract:
An image reflector assembly (22) comprises: a faceted reflector (32) configured to overlay a dashboard (26) area of a vehicle (12) and define an array of reflective facets (34), wherein each facet is configured to reflect cooperatively a portion of a projected image (20) from a projector (18) to form a reflected image (24) directed toward a windshield (14) of the vehicle (12); a light diffusive layer (36) configured to diffuse the reflected portion of the projected image (20) such that the reflected image (24) can be seen by an occupant (16) of the vehicle (12) as a reflection in the windshield (14); and a light control film (38) interposed between the windshield (14) and the faceted reflector (32), said film (38) configured to propagate preferentially the projected image (20).
