RealD Precision White Screen is Good for 3D AND 2D

RealD Inc. announced at CinemaCon this week  the introduction of its Precision White Screen technology for cinema projection, combining 2D white screen performance with the ability to project polarized 3D stereoscopic images.

Designed to deliver enhanced 2D and 3D presentations with wide viewing angles similar to white screens of equivalent gain, Precision White Screen technology features edges 4 to 5 times brighter than a standard silver screen. The improved screen efficiency results in 40% more total light coming off the screen, providing more uniform brightness than a standard silver screen.

Precision White Screens

Precision White Screens feature a smooth, white surface which generates better image contrast for improved image quality in 2D and 3D. Precision White Screen technology is expected to be available exclusively to exhibitors, production and post-production facilities utilizing RealD 3D Cinema Systems initially through Ballantyne Strong’s Strong-MDI. Additional details on price and availability are to be announced.

Precision White Screen technology delivers high quality 2D and 3D images with better brightness uniformity for an exceptional image on screen. With up to a forty degree half gain angle, optimal reflection performance can be designed for individual auditoriums depending on screen size and curvature; high gain for extra brightness or broader distribution of light for wider viewing angles,” said Joe Peixoto, President, Worldwide Cinema at RealD.

The RealD Precision White screen allows for a brilliant presentation with very even brightness and smooth texture to the image. It is simply the best 3D I have seen. And 2D presentations on this surface have a forceful visual impact when compared to a silver screen. Combined with the RealD XL’s high light output, this screen provides the best 3D cinema presentation available today,” said Ian Bidgood, Technical Director – Digital Intermediate, Park Road Post Production which utilized a Precision White Screen for the world premiere of The Hobbit: An Unexpected Journey.

 RealD Polarized Passive 3D

RealD is the world’s most widely used 3D stereoscopic cinema technology with approximately 22,200 screens equipped with RealD 3D by approximately 1,000 exhibitors in 68 countries around the world (figures as of December 31, 2012).

Brightness

Note that to keep the same brightness as on a high gain silver screen, the exhibitors using the new polarization-preserving white screen will need to increase the light output of their projectors. 

RealD is right when stating that - with the same projector- brigthness will increase for viewers at the far edges of the theatre, but neglected to acknowledge this is accompanied with a decrease of brightness for viewers in the center (where I always sit) !

Laser projectors are around the corner so there is hope that we will  be able to watch 3D with a 14 Foot-Lamberts brightness (as God intended) one day...

Screen brightness and light efficiency of the various 3D glasses technologies are discussed in chapter 8 of "Digital Stereoscopy", the bible of modern 3D technologies.
