“…High contrast ratio is key to giving a film-like experience in Electronic Cinema. 7 ILA ® projectors achieve their sequential high contrast ratio of >1500:1 by combining a continuous, specular ILA ® image source with polarized light. The use of polarized light can give the highest contrast ratios in optical systems because the use of cross-polarization is very effective in stopping rejected light from reaching the projection screen.…”

The use of video for the replacement of 35mm film presentation Electronic Cinema offers many potential advantages in the production, distribution, and exhibition of motion pictures. A key enabling component for Electronic Cinema is the video projector which must provide the image quality and brightness required to replace film projection in a theatre venue. New ILA® projectors have been developed to meet these stringent requirements. ILA® projectors provide up to 17,000 lumens, greater than 2000 TV lines of horizontal resolution, and over 1500:1 sequential contrast ratio. The unique ILA® device design has no pixel structure so that film‐like images are projected. This paper will discuss these requirements for electronic cinema and review ILA® projector technology and performance.
