Holographic projection can be used in many fields and many environments. And the price is relatively low. Generally, a complete set of holographic projection equipment costs about 200 thousand. Moreover, in terms of technology, the traditional projection of holographic projection is also very different: the clarity, fidelity and stereoscopic impression of imaging are better than those of traditional projection technology, which breaks through the limitations of traditional projection, and the spatial imaging becomes bright, with high contrast and clarity, and the sense of space and vision is also shocking, so holographic projection technology will produce shocking display effects; The influence of holographic projection display is not limited by any space and venue, and the display methods are very rich. There are many methods, such as 360/270 degree holographic projection, phantom imaging, mirror holography, single-sided holography, holographic window and so on. Each display mode has its own advantages.

◆ Competitive disadvantage

Due to the low technical level, the application of holographic projection technology is not very popular at present: according to the difference of principle, cost and effect, mature holographic projection technology can be divided into four categories: according to the difference of principle, cost and effect, mature holographic projection technology can be divided into three categories: polarized three-dimensional, stereoscopic three-dimensional and DLP link technology.

Polarized 3D: Two projectors are required to be used together, which increases the cost. The positions of the two projectors need to be adjusted accurately, and they can't be moved at will, so the later maintenance is more troublesome.

Stereo 3D: This specification has few film sources, and the use of infrared transmission signals is easily limited by viewing angle. Therefore, in order to let viewers in different positions see stable 3D images, many infrared emitters will be needed.

DLP link technology: the content is less, which affects the popularization of this technology.

But I believe that with the continuous development of science and technology and the continuous improvement of technical level, holographic projection will be widely used in everyone's life, some of which can only be used in movies.

◆ Opportunity

According to the industry, the sudden outbreak of Pokemon Go in July this year and the CG performance of holographic projection that sensationalized the world in the last 8 minutes of the curtain call of Rio Olympic Games all indicate that augmented reality has begun to show great application potential. At present, Samsung, Facebook and other technology giants have joined the field of holographic technology. The continuous attention of the market to holographic projection technology shows that this technology has good market development potential.

◆ Threats

At present, holographic projection technology is still in the development stage. Although it has a promising form, its popularization is limited because of its immature technology. In this process, similar banned products appeared.
