One or more perforation hole pattern methods are applied (402) to generate a spatial distribution of perforation holes forming a semi-random pattern for an image display screen. The image display screen is perforated (404) with the spatial distribution of perforation holes forming the semi-random pattern. Image rendering light is emitted (406) with a light projector toward the image display screen that is installed in an image rendering environment. At least a portion of the image rendering light emitted from the light projector is reflected (408) by the image display screen, toward a viewer.

A projection screen apparatus is disclosed for displaying an image projected by a projector. The projection screen apparatus includes a frame and a screen. The frame includes a plurality of frame members and corner members.

A modular curved projection screen includes an outer structural component formed of multiple compound curved interlocking sections. Multiple inner compound curved screen components are each supported by a corresponding compound curved interlocking section and extend beyond edges of the interlocking sections. Responsive to interlocking the multiple compound curved interlocking sections, edges of adjacent screen components are compressed against each other to form a smooth concave projection viewing area supported by the outer structural component.

An immersive display system is disclosed that includes screens configured to mitigate reduction in contrast ratio due at least in part to peripheral light incident on the screens. The immersive display system includes at least two screens and at least two projector systems. The screens have a multi-layered structure configured to selectively reflect light in a tailored polarization state. Adjacent screens can be configured to selectively reflect light in orthogonal polarization states. The projector systems can be configured to project video onto their respective screens with light in a suitable polarization state. The screens can be further configured to selectively reflect light within a plurality of tailored spectral bands, the spectral bands being different for respective screens.

Light emitting displays can be used in cinemas for cinema presentations that integrate a sound system to achieve immersive conditions in cinema theatres. In an example, a theatre includes a viewer seating area, an active display, and one or more sound wave emitters. The active display includes light emitting elements configured to output, toward the viewer seating area, light representing a visual presentation. The one or more sound wave emitters can be positioned proximate to the viewer seating area. The one or more sound wave emitters are configured to output, toward the active display, sound waves corresponding to at least a portion of sound for the visual presentation. The active display can be positioned to reflect, toward the viewer seating area, the sound waves from the one or more sound wave emitters.

Light emitting displays can be used in cinemas for cinema presentations that integrate a sound system to achieve immersive conditions in cinema theatres. The cinema screen can include a matrix of light emitters and a diffuser sheet. The matrix of light emitters is configured to form a light-emitting area of the cinema screen. The diffuser sheet includes one or more perforations, and can be positioned between the matrix of light emitters and an audience area in the theatre. The diffuser sheet is positioned with respect to the matrix of light emitters such that the one or more perforations are configured to prevent light outputted by the light emitters from being viewable in the audience area.

The present application provides an electronic device. After a display screen of the electronic device is attached to a screen frame, the display screen extends beyond the screen frame at at least two opposite edges and extends toward the second side of the display screen by taking the screen frame as an axis, and then the display screen is mounted by a mounting structure connected with the screen frame, so that the display screen is kept flat by a tensile force provided to the display screen via the mounting structure.
