A hologram from Star Wars on your smartphone? Samsung already has a patent application

The Korean smartphone manufacturer has boasted its latest patent, thanks to which next generations of Galaxy will display three-dimensional holograms from Star Wars. Well, I will believe when I see.

Forgive my skepticism. But about the fact that some company will in a moment present a way to display real, three-dimensional holograms I've heard dozens of times. Nintendo of its time advertised in this way its portable 3DS console, in which the 3D effect was achieved using an old trick with two screens and a slightly modified image, displayed for each eye.

When it comes to the last wave of unsuccessful experiments with 3D images, the RED Hydrogen One smartphone deserves an honorable mention. Its display could work in 3D mode without the need for special glasses. TV manufacturers have experimented with the same solution a few years ago. Its acceptance by clients is best evidenced by the fact that this year's smart tv (apart from a few survivors) no longer offer this function.

Holographic displays exist. But they are not suitable for home use

At this point, three solutions deserve mention. The first of them is the Heliodisplay holographic projector. To simplify it, it works as follows: we have a strip that emits micro-particles of some kind of gas (the producer obscures trade secret), from which the image from the projector is reflected. It looks quite futuristic now. Although the two-dimensionality, the waving and the general imperfection of the image thus displayed make it a rather curiosity that can be looked at for a while in the shopping center, rather than a product on which I would like to watch films at home.

Another invention that resembles the most fictional universe is the Japanese LPEID projector (Laser Plasma Emission 3D Image Display), presented at the CES in 2011. Here the image is fully three-dimensional, but we can only dream about displaying it in several million colors. This is due to the way it works: because the projector emits high-energy laser beams that intersect to form a voxel-visible plasma. A very ingenious solution, but again - with holograms from Star Wars, it's terribly poor.

Idea number three comes from Poland and is called Leia Display System . Yes, it's about this Leia. Unfortunately, the Polish device is also limited to displaying the image in two dimensions. In addition, the role of the screen here is a layer of water vapor, which intersects the home use of LDS (unless you do not mind the fungus on the wall) and makes the picture will never be sharp. The idea itself is quite good and probably would work as an advertising billboard (fogboard?) In a shop window or on the stage of a theater, but that's it.

Samsung claims that his patent is completely different

holographic display of samsung patent

In the patent application submitted to the World Intellectual Property Office and the United States Patent and Trademark Office, we can read about the use of spatial light modulators and the phenomenon of diffraction (light scattering). The description is not too extensive, of course, but it is hardly surprising. This is finally a patent application. It is not even known whether Samsung decided to report it in the dark, or indeed it already has a prototype of a device capable of displaying three-dimensional holograms hovering above the phone display.

I hope it will. I miss some new wow effect, which would shock the recently fused smartphone market. Every year, we get the same from the producers: a bit better camera, a bit faster components and a slightly wider screen. Boredom. That's why I keep my fingers crossed for Samsung. If their holograms prove to be another dump, then the smartphones are still being folded . Something will eventually happen.
