Abstract
Disclosed is a large-viewing-angle integral imaging 3D display device based on secondary light field modulation. The device includes a 2D display screen, a light field guiding layer and a light field reconstruction layer. The 2D display screen is located at a bottom layer of the device, and the light field guiding layer and the light field reconstruction layer are located above sequentially. The 2D display screen displays an interleaved coded elemental image array and provides an interleaved light field for an upper structure of the device. The light field guiding layer performs first light field modulation and is configured to modulate light emitted from the 2D display screen and guide and separate interleaved light field with different viewing area information in space. The light field reconstruction layer performs secondary light field modulation, and is configured to reconstruct and splice separated light beams modulated by the light field guiding layer.
