“…They are based on wavelength multiplexing, polarization multiplexing, or time multiplexing (using active shutter glasses) of the images for the left and the right eyes. Both wavelength multiplexing and polarization multiplexing can be time parallel (two projectors) or time sequential (one projector) . Polarization‐based 3D requires a polarization preserving projection screen, whereas wavelength multiplexing stereoscopy can be used with any standard front or rear projection screen.…”

-The achievable color gamut and light output of projection displays based on light-emitting diodes (LEDs), phosphor conversion, and lasers are discussed. The color appearance phenomena, colorfulness, and the Helmholtz-Kohlrausch effect are discussed in the context of LED and laser illumination of projection displays, as well as some pitfalls concerning the interpretation of the HelmholtzKohlrausch effect. Also the laser speckle phenomenon and the characterization of it are addressed. The importance of both the American National Standards Institute (ANSI) contrast and the sequential contrast of projectors, as well as the discrepancy between measured and perceived contrasts, are explained. Visibility criteria for contouring artifacts are explained and compared with new emerging electro-optical transfer functions that are more adapted to this issue. Stereoscopic solutions and early prototypes of autostereoscopic multi-view, super multi-view projection displays, and electroholographic displays are discussed as well as the limiting factors of these systems in the context of display resolution, and LED and laser light sources.

“…It is assumed that laser illumination will provide sufficient headroom to satisfy peak-brightness/uniformity requirements on PLF-sized screens in 3D; collectively, a very tall order. Notwithstanding the importance of a 3x boost in projected lumens, lasers also offer features that improve the 3Defficiency 3 . The flexibility to tailor the RGB power spectrum without attenuation eliminates color-balance loss.…”

The final word on 3D-cinema entertainment value cannot be written until patrons experience stereo-images of uncompromised quality. There has always been a performance cost associated with the addition of 3D, and as technology enables better 2D images, there is a threat that this situation will persist. We will examine the technical challenges of achieving the holy-grail for 3D; a compromise-free stereoscopic 3D presentation, in the face of new proposed 2D standards.

“…In such conditions, human perception operates on the boundary between mesopic and photopic vision, where spatial acuity, perceived contrast, depth perception, and color vision are significantly affected [2,3,4]. A natural solution to the problem is to provide brighter projectors [5]. This, however, leads to significantly increased operating costs since brighter projection lamps consume more energy are more expensive and burn out more quickly.…”
