Abstract: A display system includes a pixelated display being curved about at least one axis and including a plurality of groups of pixels; a plurality of light redirecting elements where each light redirecting element corresponds to a different group of pixels in the plurality of groups of pixels; and an optical lens system adapted to receive light emitted by the pixelated display and transmitted by the plurality of light redirecting elements. The optical lens system transmits at least a portion of the received light. For at least one pixel in the plurality of groups of pixels, the light redirecting element corresponding to the pixel reduces an angle between a central light ray emitted by the pixel and a chief light ray emitted by the pixel.

Abstract: A display system including an imager for forming an image, and a projection lens system for projecting the image formed by the imager is described. For each pixel in the plurality of pixels, the imager is configured to emit a cone of light having a central ray having a direction that varies with location of the pixel in the imager. The variation may increase a brightness of an image projected through the projection lens system by at least 30 percent. The display system may include a light guide having a light insertion portion adapted to receive light; a light transport portion disposed to receive light from the light insertion portion; and a light extraction portion disposed to receive light from the light transport portion.

Abstract: Light emitting systems and optical systems including a light emitting system and a lens system are described. The light emitting system includes a pixelated light source having a plurality of discrete spaced apart pixels, and includes a plurality of light redirecting elements, each light redirecting element corresponding to a different pixel in the plurality of pixels. The light redirecting elements may be adapted to alter one or both of a central ray direction and a divergence angle of light received from the corresponding pixel. A lens system disposed to receive light from the light emitting system may include a reflective polarizer and a partial reflector.

Abstract: An optical system for displaying an object to a viewer is described. The optical system includes an integral first optical assembly, an integral second optical assembly, and an integral third optical assembly disposed between the integral first and second optical assemblies. The integral first optical assembly has a first focal length and includes one or more first optical lenses, and a reflective polarizer. The integral second optical assembly has a second focal length and includes one or more second optical lenses, and a partial reflector having an average optical reflectance of at least 30% for a desired plurality of wavelengths. The integral third optical assembly has a third focal length and includes a curved first phase retarder. The third focal length is greater than a smaller of the first and second focal lengths.
