    Abstract: A display device includes a light source array including a plurality of light sources where at least one of the plurality of light sources is selectively driven, a spatial light modulator for modulating light from the light source array to form image light, a focusing optical system for focusing the image light formed by the spatial light modulator at a position in a predetermined eye box, a micro mirror array arranged in an optical path formed in the focusing optical system and including a plurality of mirror cells. The plurality of mirror cells are controlled to be in an ON state in that light is reflected in a direction toward an inside of the eye box or to be in an OFF state in that light is reflected in a direction toward an outside of the eye box.

    Abstract: An augmented reality (AR) device includes a light source; a light source-moving delta robot on which the light source is mounted, the light source-moving delta robot being configured to change a traveling path of light emitted from the light source by adjusting at least one of a position or a slope of the light source in a three-dimensional (3D) space based on a movement of the light source-moving delta robot; a display device configured to generate a first image by modulating the light emitted from the light source; and a combiner configured to combine the first image generated by the display device with a second image, which is different from the first image and is received from an external source, and output a combined image.

    Abstract: A head-up display system includes an image generating apparatus configured to emit light having a first polarization and including image information; a polarization beam splitter provided on an optical path of the light having the first polarization and configured to transmit the light having the first polarization; a wave plate configured to transmit the light transmitted through the polarization beam splitter while changing a phase of the light; and a mirror configured to reflect the light sequentially transmitted through the polarization beam splitter and the wave plate back to the polarization beam splitter through the wave plate. The polarization beam splitter may reflect light having a second polarization that is different from the first polarization and obtained by transmitting the light reflected by the mirror back through the wave plate.

    Abstract: An anamorphic optical system and a display apparatus including the same are disclosed. The anamorphic optical system includes an illumination system having astigmatism, and first and second correction lenses that are provided to have tangential power and sagittal power respectively and correct the astigmatism in the illumination system. The first and second correction lenses are provided in which a difference between a distance from the first correction lens to a tangential image formed by the first correction lens and a distance from the second correction lens to a sagittal image formed by the second correction lens corresponds to a distance between the first correction lens and the second correction lenses, and at least one of the first correction lens and the second correction lens has an asymmetric stop to form the tangential image and the sagittal image on the same surface.
