What's the difference between laser IMAX and ordinary IMAX?

The first thing we need to know is that the IMAX we usually go to the cinema is digital IMAX.

Introduction to IMAX:

1, configuration difference:

IMAX (digital) refers to the digital IMAX cinema. At present, there are about 600 commercial IMAX cinemas in China. Digital IMAX is projected by using xenon lamp light source. The resolution is 2K. Compared with 2000: 1. Brightness 6FL- 14FL speaker 5. 1 channel. The number of digital IMAX xenon lamp theaters accounts for more than 98% of all commercial IMAX theaters in China.

2. Cost difference:

The cost and operating cost of the new generation laser IMAX cinema are more than twice that of digital IMAX cinema, 10 times that of laser IMAX cinema and 20 times that of film IMAX cinema.

3. Different screen sizes

At present, the screen sizes of all commercial cinemas in China are as follows (minimum-maximum). Digital IMAX: screen width: 14m ~ 25m, screen height: 7m~ 14m. A new generation of laser IMAX: screen width: 16m ~ 25m, screen height: 8m~ 14m.

The development of IMAX:

1. The original IMAX was shown in the form of 70mm film, but due to the high equipment and cost, only some documentary demonstrations were shown, and there was no room for development into a commercial model.

2. In the late 20th century, the first digital use of IMAX film was xenon lamp, referred to as digital IMAX. Although the image is large, the contrast, brightness and resolution are obviously reduced, but the cost is also greatly reduced. So it can be developed into a commercial cinema model. At that time, the audience only saw the big picture but didn't know much about the picture effect.

3.265438+At the beginning of the 20th century, with more and more audiences aware of the shortcomings of digital IMAX and the rise of Dolby Cinema, the rapid development of IMAX slowed down. In order to make up for the deficiency of digital IMAX, IMAX company contacted laser manufacturers to develop laser IMAX. Even the digital IMAX using laser light source is called laser IMAX for short. There are only four Guiyang cross-border IMAX studios in China, which is one of them, but there will be a lot of problems in the early development of new technologies.
