Film screening technology started late in our country, with the continuous improvement of economy and technology, the technical level of film screening in China has been improved. In the early days of China's liberation, film screening technology with the use of foreign production of screening equipment for Black-and-white silent film playback; In the context of the continuous development of science and technology, in the Sixties or seventies of the 20th century, Black-and-white film developed into color film, and independent research and development of China's intellectual property rights of the projector, with the Greatly accelerated the development of China's film screening technology. In the the 1990s, the projection technology was mainly transformed into digital projection technology, in the premise of gradual improvement in picture quality, people put forward new requirements for sound, so we introduced foreign sound-reading, double red-tone components and other advanced equipment. With the continuous improvement of the technical level of film screening, digital back-loop technology, processor computer control technology, power modular switching projection technology, brightness and high gain technology and surround sound technology have been innovative development, film technology has a new revolution. After entering the 21st century, the film technology has been a new breakthrough, the original 3D film based on the improvement of the formation of the digital 3D film, China's film screening technology to a new level.

Film screenings after decades of development, the realization of the current best film screening technology, digital 3D film is currently occupied by the mainstream film market model, the current 3D show mainly three kinds of screening technology, namely, circularly polarized light technology, spectral filtering color separation technology and alternate transmission of light technology. These three kinds of 3D innovative digital film projection technology are widely used at home and abroad.

Circularly polarized light technology, which is a reald3d, is a method of simulating human eye observation scenery, by setting two parallel cameras to simulate the human left and right eyes, and simultaneously shooting two films with slightly horizontal parallax. Projection in the left and right two sets of projectors mounted in the film, and in front of the two projectors placed two polarization axes each 90 degrees of polarization mirror, two cameras imitate the eyes of the observation way to show at the same time, and eventually put the picture on the metal screen, forming about the image. When the audience with a special polarizer, the left eye can only see the left image, the right eye can only see the right image, and finally through the eyes and the joint action of the cranial nerve to form a stereo screen. In the use of circularly polarized light technology in the need for the polarizer at the same time screen texture has a higher demand, circular polarization technology screen texture must be metal material, the so-called metal screen is the white metal powder smear on the surface of the screen, so that the screen reflects a variety of colors, increase the picture of the film and film Screen brightness. But the high cost of the metal curtains increases the cost of film screenings.

The digital projection technology based on spectral filtering color separation technology is Dolby system. In the realization of the film stereo effect, different from the traditional red and blue filter technology, du 3D system screenings without the red and blue color of the left and right eyes, but the filter wheel coated multilayer coating, directly placed in front of the optical lens. In the film screening, the audience wearing a film of the same membrane will be a stereo effect, this technology does not need to have any processing on the screen, the original ordinary white screen can meet the playback conditions, so the spectral filter color separation technology is widely used in major cinemas.

The alternate transfer optical technology is a product of the development of digital technology, and the Xpand system which is still in use is based on the design of alternating light technology. The main components of the Xpand system are electronic LCD glasses, infrared signal transmitters and 3D synchronous signal converters. In general, technicians place infrared transmitters in front of the theater to facilitate the screening. C Signal, and for the audience to pass the signal, the audience by wearing a stereo LCD glasses will feel the stereo film image. Alternate transmission of optical technology also has no special requirements on the screen, but its important components of LCD glasses cost higher, and the glasses themselves device of the battery will cause the overall weight of the glasses, not conducive to enhance the audience to the comfort of the shadow. In addition, the glasses of the battery requires staff to replace the regular, this also for the theater show management caused some unnecessary trouble, so the alternative transmission of light technology is mostly used in small, easy to manage the smaller screening hall.

In a short span of dozens of years, people's demand for film screening technology is constantly improving, and in the continuous progress of science and technology, China's film screening technique has realized the change from silent to sound, from black-and-white to color, from film to digital film. China's film screening technology is at a rapid pace of innovation and development, its innovative results more and more to meet the increasing standards of the public. Digital projection technology is a more advanced screening technology, gradually become the film industry widely used screening technology, digital 3D Stereo show will be the film development in the next few decades the mainstream projection mode. With the continuous innovation of 3D projection technology, we can boldly speculate that the future of the film can be created without 3D glasses also can achieve 3D effect of the film screening technology, that is, the continuous development of 3D technology may create a naked eye 3D effect. The advantage of the naked eye 3D is that it can get rid of the discomfort caused by the glasses, but also enjoy the 3D stereo effect. At present, the open hole technology is in the research and development, and it is applied to the industrial commercial display market. It is believed that in the near future, open-hole 3D and more advanced screening technology will become a reality and promote a new breakthrough in film screening technology.

Digital projection technology based on its own advantages can visually give the audience a great shock, and in the hearing of the audience with a huge impact. China's digital screening technology started late, the application time is not long, and the advanced level of developed countries still have a certain gap, the film screening technology innovation and development need to continue to research, improve the level of scientific practice innovation to support new technology research, improve film screening professional technical level, In order to promote its level, we should seek the independent research and development of film screening technology.

Film screening technology from the silent era gradually developed into a sound era, color ERA and the current digital era, the rapid development of film screening technology is inseparable from advanced science and technology and the impetus of innovative results. The innovative development of film screening technology has brought new ideas to film art creation and film production technology, in the future, the innovation and development results of digital era will bring unprecedented progress to the development of film and television art, while maximizing the satisfaction of people's visual enjoyment.
