Abstract: With the advancement of new media, cinema today is in an “expanding” situation. “Screen”, a core component of film installation, is also reshaping its form, connotation and relationship with the audience. At one time, cinema was regarded as Plato’s cave while  screen became a device for display or shielding, which confined the audience’s positions. With the introduction of new technologies, screen may become a portal for the audience to enter the myth of the mirror world (AR) and the meta-universe (VR), echoing the prediction in the early film that “Uncle Josh” will enter the “moving pictures”. In addition, screen is gradually getting away from cinema devices, and the new screen, which is gathering the functions of panoramic monitoring tools and data streams, is constructing a new relationship between the screen and the audience.

Key words: silver screen, screen, interface, metaphor, viewing relationship
