Combining a 1.8-inch transmissive LCD panel as a spatial light modulator with what they describe as a photon sieve, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have demonstrated an ultrathin display that can project dynamic, multi-coloured, 3D holographic images.

Previous studies from Professor Park’s group have used optical diffusors for the same purpose, but the size of the device was bulky and difficult to be operated, and it took a long period of time to calibrate. In the present work, on the other hand, the group tailored their photon sieve to demonstrate a simple, compact and scalable method for 3D holographic display. This technique can be readily applied to existing LCD displays, the authors argue.
