Abstract
The present disclosure relates to a holographic display device and an electronic device. The holographic display device may include a light source, a light transmission structure, a first photonic crystal group, and a spatial light modulator. The light transmission structure has a light incident surface and a light exiting surface. The first photonic crystal group is disposed between the light incident surface and the light source. The first photonic crystal group includes various photonic crystals for dividing light emitted by the light source into light beams of different colors. The light beams of different colors are transmitted into the light transmission structure through the light incident surface and emitted through the light exiting surface. The spatial light modulator corresponds to the light exiting surface for modulating light beams of different colors emitted from the light exiting surface to form a holographic image.
