  3. Projection screen - Wikipedia

    en.wikipedia.org/wiki/Projection_screen

    Apparent contrast in a projected image — the range of brightness — is dependent on the ambient light conditions, luminous power of the projector and the size of the image being projected. A larger screen size means less luminous (luminous power per unit solid angle per unit area) and thus less contrast in the presence of ambient light. Some ...

    Projection gauge is the film gauge (width) used for the release print.

    1080p progressive scan HDTV, which uses a 16:9 ratio. Some commentators also use display resolution to indicate a range of input formats that the display's input electronics will accept and often include formats greater than the screen's native grid size even though they have to be down-scaled to match the screen's parameters (e.g. accepting a 1920 × 1080 input on a display with a native 1366 ...

  7. Overhead projector - Wikipedia

    en.wikipedia.org/wiki/Overhead_projector

    An overhead projector works on the same principle as a slide projector, in which a focusing lens projects light from an illuminated slide onto a projection screen where a real image is formed. However some differences are necessitated by the much larger size of the transparencies used (generally the size of a printed page), and the requirement ...
