Samsung is developing a new holographic technology for their smartphones, as patent application with the title “Hologram Reproducing Apparatus and Method Thereof” shows. How it would be different from the RED HYDROGEN ONE? Read below.
The technology aims to allow a real holographic display which produces a hologram imagery straight from the phone’s display. Sounds fictional? According to the highly detailed patent application it’s realistic scenario.
True holographic display
As stated in the abstract: “A hologram reproducing apparatus is provided that includes a display configured to display a hologram pattern and emit a write beam corresponding thereto, a relay lens disposed at a front surface of the display and comprising an array of micro lenses each focusing the write beam, a spatial light modulator (SLM) disposed at a front surface of the relay lens, configured to write the hologram pattern according to the focused white beam and modulate a reproduction beam into a plurality of diffraction beams”. If you’d like to dive further into details, you can read the whole application here.

Much more advanced than RED HYDROGEN ONE
Current holographic technologies require you to look directly at a 2D surface with a very limited view angle, like in the Nintendo 3DS display or the RED HYDROGEN One phone.
According to Samsung’s patent application, the technology tries to mimic the Start Wars hologram. Just imagine to see a movie (or a picture) in a true holographic style right from your smartphone.

Final thoughts
It appears that the application is very detailed, and although it’s only in the application stage, the execution is just around the corner, especially when a smartphone giant like Samsung is in charge. In my opinion, we should expect to see the holographic smartphone very soon.
