摘要
Embodiments include 3D display devices and methods of operation. In an example device, a light-emitting layer is provided with an addressable array of light-emitting elements. An optical layer overlays the light-emitting layer. The optical layer includes an array of lenses operative to substantially collimate light from the light-emitting layer. To suppress stray light, an angular filter layer is provided along an optical path from the light-emitting layer to an exterior of the display. The angular filter is operative to substantially block light having an incident angle greater than a threshold angle and to substantially transmit light having an incident angle less than a threshold angle. The angular filter may be a thin-film interference bandpass filter. Different regions of the angular filter may be tuned for different wavelengths of light.
