What will be the next generation display technology? The human eye's pursuit of vision has been developing at a rapid speed. From black and white display to color display, from analog display to digital display, from low resolution to high resolution, from flat display (2D) to stereo display (3D), the pace of development of display technology has never stopped. Natural and real, three-dimensional visual effects are people's ultimate pursuit. What will the next generation of display technology be? Is it a holographic display? Will the high technology appearing in Hollywood movies come into our lives? Can we watch movies or TV shows or play games at home with those hi-tech display?
What is a holographic display?
The holographic display uses the interference and diffraction of light waves to suspend the three-dimensional image of the object in the mid-air of the real scene. People can see the illusion of real or virtual objects, creating an atmosphere of real and fantasy, with a strong sense of depth and technology. Because all the three-dimensional information of the object is recorded and presented, the image presented is closer to the real thing. The holographic display is more in line with the human eye's viewing habits, avoiding the conflict between the human eye's convergence and focusing during stereoscopic viewing, which can make people feel the pleasure of being "immersive" for a long time.
Those who need to rely on various media (such as holographic projection films, water mist, transparent glass, walls, etc.) to achieve 3D effects with the help of the Porbol illusion or the edge elimination method (obstructive eye method) are not true holographic displays. technology.
At present, there is no low-cost and stable medium for holographically displayed stereoscopic information, which can carry the stereoscopic information.
At present, internationally renowned universities and well-known enterprises are constantly increasing their investment in research and development of holographic display solutions, key materials, optical components and visual tracking, and have made important progress. As the holographic technology matures, the upgrading of micro-nano processing technology and materials, and the empowerment of other technologies (such as 5G, VR/AR, AI), the door of the locked holographic market will accelerate.
