    Abstract: A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.

    Abstract: A system and method of displaying a conformal-capable head-up display image is provided. A pre-distorted right-eye image and a pre-distorted left-eye image are separately generated and projected toward a windscreen. The pre-distorted right-eye image is reflected off of the windscreen to supply a reflected right eye image to a right eyebox, and the pre-distorted left-eye image is reflected off of the windscreen to supply a reflected left eye image to a left eyebox. The reflected right-eye image and the reflected left-eye image are each non-distorted images.

    Abstract: An augmented display system with dynamic see-through transmittance control is disclosed. The augmented display system includes: an augmented display screen; a tandem electrochromic (EC) filter disposed over the augmented display screen. The tandem EC filter includes a first window having a dominant first transmittance characteristic and a second window having a dominant second transmittance characteristic; and an augmented display transmittance controller configured to individually control the activation of the first window and the second window of the tandem EC filter, wherein the augmented display transmittance controller is configured to: determine from an ambient light sensor output the transmittance required from the first window and the second window for a selected augmented display luminance; and apply appropriate drive voltage waveforms to the first window and the second window to achieve the determined transmittance.

    Abstract: A virtual window display includes: a plurality of collimated projector modules having contiguous exit pupils. Each collimated projector module includes: a display device configured to display a spatially modulated image along a flat or curved geometric image surface, and one or more optical lenses sharing a common curvature symmetry axis and configured to optically collimate light from the display device in the collimated projector module. The curvature symmetry axes of the plurality of collimated projector modules point in a plurality of angular directions and are substantially convergent along at least one axis at a finite distance from the plurality of collimated projectors. The total display FOV of the virtual window display is larger than the module FOV of each of the plurality of collimated projector modules.
