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

Light emitting displays and sound systems can be used in cinemas for cinema presentations that integrates a sound system to achieve the same or better immersive conditions in cinema theatres with front projection cinema screens. The screen can be active with light emitters, rather than passive and reflect light projected from a projector. Spaces are formed between adjacent light emitters in the display to allow for sound waves to pass from sound wave emitters positioned behind the screen to a cinema seating area in front of the screen. Loudspeakers may be positioned in the spaces. Diffusers or other structures may be positioned proximate to a front of the screen to facilitate visual performance. In addition or in the alternative, loudspeakers can be positioned in each seat of the viewing seating area that produce sound waves that appear to be coming from a non-seating location in the theatre.

A dome screen for preventing generation of a missing part of a star projected on the dome screen is provided. A dome screen 10 capable of projecting an image includes a dome portion 11 and a sheet portion 12. The dome portion 11 has a plurality of holes and is formed in a hemispherical shape. The sheet portion 12 is arranged on an outer side of the dome portion 11 so as to overlap with the dome portion 11 and has light reflectivity.

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.

An acoustical screen that can be utilized in a variety of applications including as part of a projection screen to cover and hide the presence of an audio speaker. The acoustical screen is formed using multiple hole sizes, e.g., three or more hole diameters or outer dimensions if not round. These differently-sized holes are placed in pseudo-random positions so that there is no perceivable repeating pattern of hole placement in the acoustical screen. By avoiding an ordered grid of holes of a single diameter as in prior speaker grills, the new acoustical screen disguises the visible reflection pattern through non-uniformity. It also provides an improved acoustic transmission surface that allows sound with a greater variety of wavelengths to pass while reflecting a less pronounced echo. The acoustical screen will be in demand for use in entertainment venues using projection systems with speakers positioned behind a front projected screen.

An accessory suitable for an electronic device is provided. The electronic device has a display area. The accessory includes a coupling portion and a cover portion. The coupling portion is suitable to be coupled to the electronic device. The cover portion is connected to the coupling portion and is suitable for covering the display area of the electronic device. The cover portion has a plurality of light-transmitting areas, and the light-transmitting areas are arranged on the display area in an array. An image generated by the display area is projected out of the cover portion through the light-transmitting areas. Moreover, an electronic assembly containing the electronic device and the accessory is also provided. Furthermore, a control method is also provided for controlling the electronic assembly. A method is also provided for forming an accessory.
