ScreenX is a panoramic film format which presents films with an expanded, dual-sided, 270-degree screens projected on the walls in a theater.[1] First introduced in 2012, it is created by CJ 4DPLEX, a subsidiary of the CJ CGV group which also created the 4DX motion-theater technology, which uses a similar logo and combines both formats, known as Ultra 4DX.[2] Co-developed by KAIST, it is considered a "sideways" version of IMAX and a presumed competitor to streaming platforms such as Netflix. As of 2022, the theater technology is installed in 364 screens in 37 countries.
