Abstract
Systems and methods are described for providing a 3D display, such as a light-field display. In some embodiments, a display device includes a light-emitting layer comprising an addressable array of light-emitting elements. An optical layer overlays the light-emitting layer. The optical layer includes a plurality of distributed lenses. In some embodiments, the distributed lenses include non-contiguous lens regions. In some embodiments, distributed lens regions with different optical centers are interlaced with one another. A spatial light modulator is operative to provide control over which lens regions transmit light from the light-emitting layer outside the display device. In some embodiments, the use of interlaced and/or non-contiguous distributed lenses provides improved display resolution with a reduction in diffraction effects.
