Research on 3D Display
Samsung Electronics said on Nov. 10 (local time) that a research paper on "thin holographic displays" by the Samsung Advanced Institute of Technology was published in the world-renowned journal Nature Communications. It took eight years for the research center to write the paper.
Hologram technology creates vivid images as if there were real objects in front of eyes. A hologram display is similar to a high-resolution display commonly used in everyday life, but there is a big difference between the two in terms of dimensions.
Holographic displays are considered the most ideal 3D displays among many displays that show 3D images.
Hologram is a technology with infinite scalability as it can be applied to various fields such as meeting hospitalized persons in isolation wards, virtual designs, navigation, and creating realistic images of ancient artifacts. However, if a hologram image is enlarged, the viewing angle narrows and if the angle is widened, the hologram image becomes smaller.
Researchers at the lab have developed a special optical device called “S-BLU” to solve problems with narrow viewing angles. By using this technology, the viewing angle can be widened 30 times by deflecting a hologram image in the direction of an observer. Another major achievement of the researchers is the presentation of a method that can produce 4K hologram images in real time.
"We need more research and development before we can smoothly use holograms in our daily lives," said Won Kang-hee, a researcher at the institute. "However, we expect that a limited use of small hologram images will be realized earlier. For example, we will be able to use a virtual hologram keypad for automation devices and select products by using hologram images.”
