Why is the screen ratio of the cinema 2 1:9? Instead of the traditional 16: 9 or 4: 3?

The screen ratio of the cinema is 2 1:9, mainly based on the audience's viewing experience. For the convenience of the audience, if the screen is wider, the field of vision will be wider, and the audience sitting on both sides can enjoy the movie better. And 16:9 and 4: 3 are relatively narrow screens, which are mainly suitable for computer or TV users.

Extended data:

16∶9 is the most suitable format for human eyes, with stronger visual impact. At the same time, the display format of digital TV in the future will also adopt 16∶9 format. At present, 4∶3 is a more suitable display format for analog TV signals. If it is mainly used for watching TV, it still has certain advantages. It should be pointed out that at present, many TVs with 16: 9 and 4: 3 formats can adjust the display format of the picture through the menu, but this is at the expense of wasting a certain screen area.
