Abstract: An optical display system and an electronics apparatus are disclosed. The optical display system comprises: a display unit, which generate a first image light and a second image light, wherein the first image light is in a first polarization state and the second image light is in a second polarization state and the first image light and the second image light are generated by a same display panel; a resolution enhancement optic unit, which enhances the resolution of the first image light with respect to the second image light; and a magnifying optic unit, which magnify the first and second image lights from the resolution enhancement optic unit.

Abstract: An optical display system and an electronics apparatus are disclosed. The optical display system comprises: an image source, which generates image light; and an optical combiner, which includes two reflection-type polarization volume lenses working in a Bragg regime, wherein a first reflection-type polarization volume lens of the two reflection-type polarization volume lenses diffracts the image light of a first polarization to a first image and transmits the image light of a second polarization, and a second reflection-type polarization volume lens of the two reflection-type polarization volume lenses diffracts the image light of a third polarization to a second image and transmits the image light of a fourth polarization, the optical combiner outputs the first image and/or the second image as an combined image.

Abstract: A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The illumination optics may include a red, green, and blue light sources. The fLCOS panel may produce image light by modulating a series of image frames onto illumination light. Control circuitry may control the illumination optics to produce the illumination light for each image frame in the series of image frames according to a green-heavy illumination sequence that includes first, second, and third time periods. The green light source may be active during each of the first, second, and third time periods. This may allow the green light source to be driven with a lower current density than the other light sources without significantly reducing image quality at an eye box. The lower current density may match the peak efficiency of the green light source, thereby minimizing power consumption by the display.

Abstract: A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. A twisted nematic cell may be optically interposed between the fLCOS panel and the waveguide. A birefringent crystal may be optically interposed between the cell and the waveguide. The cell may have a first state in which the cell transmits the image light with a first polarization and a second state in which the cell transmits the image light with a second polarization. The crystal may transmit the image light within spatially offset beams based on polarization. In another arrangement, a quarter waveplate may be optically interposed between the cell and the waveguide and a geometric phase grating may be optically interposed between the quarter waveplate and the waveguide. Control circuitry may toggle the cell between the first and second states to maximize the effective resolution of images at an eye box.

Abstract: Perovskite-polymer composites including perovskite nanocrystals dispersed in a polymer matrix, wherein the perovskite nanocrystals have an average size of from about nm to about 20 nm. Methods for producing a perovskite-polymer composites that may include contacting a solid material comprising a polymer matrix with a solution comprising a perovskite precursor; allowing the solution to penetrate the solid material to yield a swollen solid material comprising the perovskite precursor dispersed within the polymer matrix; optionally contacting the swollen solid material with an antisolvent; and annealing the swollen solid material to crystallize the perovskite precursor and to yield the perovskite-polymer composite comprising perovskite nanocrystals dispersed in the polymer matrix.
