The concept of the holographic display using a non-periodic photon sieve. a Schematic of a lensless digital holographic display system using a single spatial light modulator (SLM). The small diffraction angle of the SLM limit the viewing angle of the holographic objects. b Schematics of a large-sized wide viewing angle holographic display system using a non-periodic photon sieve. The photon sieve diffracts light at a high angle, thus increases the viewing angle. To guarantee the whole holographic image can be observed without disruption within the viewing angle, the holographic objects should be positioned in the shaded region. Outside the region, the holographic objects are clipped, and the viewing angle is decreased
