The museum has the largest screen in China, with a width of 30*22 meters, and is famous in Beijing. The venue of the giant screen hall is rented to Poly International Cinema, which plays science and education films during the day and commercial films at night, so some ticketing websites are named "Poly International Cinema (China Science and Technology Museum Store)". In 2015, the Science and Technology Museum replaced the IMAX screen with a cheaper Chinese giant screen, and the movies played chose the "Chinese giant screen" method. China's giant screen is developed by the China Film Science and Technology Research Institute, China Film Company and other enterprises, the brightness is 15% higher than IMAX, its 11.1 channels even crush IMAX's 7.1 channels, the system parameters are very beautiful, and it is also the focus of frequent external publicity. In fact, the clarity of IMAX is far better than that of Chinese giant screens, and the clarity of films shot or converted into IMAX is 10 times that of common 35mm film films on the market, and 3 times that of traditional 70mm film films, while Chinese giant screen movies are shot with ordinary cameras, and the clarity of ordinary film sources that have been slightly corrected has basically not improved, and the two can be understood as a gap between 6k and 2k. However, the Chinese giant screen projects 2K films on a huge screen, and the image effect is good, which is because it has enough brightness to make up for the lack of clarity, so the look and feel is similar to IMAX. If you encounter some movies that use a lot of handheld photography, large close-ups, and fast editing techniques, you may have a strong feeling of vertigo and even vomiting when watching IMAX, which is not the case with Chinese giant screens. In addition, the cost of Chinese giant screens is cheap, which is good for theaters and audiences, and if you are not a loyal IMAX fan, it is also a good choice to watch Chinese giant screens. The 2D and 3D playback of the giant screen hall of the China Science and Technology Museum have a good reputation. After all, there are not many movies produced using Chinese giant screen standards, and ordinary film sources are usually played, and some films will not be screened when they are screened. The 10-12 rows of the theater, or a little further back, are more comfortable visually, and the eyes will not be able to see it in the future, the screen is too big. Every night after five o'clock, commercial films are arranged by Poly Cinemas. The seats in the giant screen hall are harder, and the design of the hall itself is to play about 40 minutes of films, while commercial films are basically about two hours. Interested audiences can also experience the dome (also known as the dome) theater in the Science and Technology Museum. This is currently one of the largest dome theaters in the world, with a hemispherical screen with a diameter of 30 meters, an area of more than 1,000 square meters for the film screen, IMAX projection equipment combined with optical planetarium, digital auxiliary projection system, suitable for displaying various astronomical phenomena, and the overall tilt of the seat is 30 degrees to create an environment for the audience to look up at the sky. Astronomical films such as "International Space Station" and "Phantom of the Universe: The Search for Dark Matter" have been broadcast for a long time, and the specific schedule can be found on the official website.
