Abstract
An active display can be used in a theatre with reduced screen-door effect. For example, the active display can have a structure, such as a diffuser structure, or a diffuser and mask structure, that can have, or appear to have, transmissive areas and opaque areas to reduce the audience from detecting gaps or other non-light sources in the active display. The active display may additionally or alternatively have audio ports to allow sound to pass through the active display and appear to the audience as if the sound is coming from the active display.
