Abstract: A multicolored optical assembly and a method for providing highlighting to an image of a multicolored baseline projector having a baseline light beam. The optical assembly can have an optical highlighter light path providing a highlighter light beam of steered light delivered to an imager. Light loss can be reduced after a spatial phase modulator in a multicolored optical assembly i.e. to use light more effectively. A method for providing highlighting to an image of a multicolored baseline projector having a baseline light beam is provided without using polarized light.

Abstract: 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.

Adjacent screens can be configured to selectively reflect light during different periods of time. The projector systems can be configured to project video onto their respective screens while the associated screen is configured to selectively reflect light rather than absorb light.

Abstract: A display method and system are described for displaying a stereo image comprising a first image and a second image. A light valve array comprising an array of light valve elements is driven according to an image and a light source is provided for generating a shaped light beam which can illuminate a portion of the light valve array. A scanning device is provided which is arranged to scan the shaped light beam across the light valve array. Light valve elements of the same light valve array are caused to sequentially adopt a state representative of the first image of the stereoscopic image and a state representative of the second image, and to cause the light valve elements to adopt a new state representative of one of the first and second images in advance of the scanning by the shaped light beam and to change to a new state representative of the other of the first and second images during a period between successive scans of the shaped light beam.
