RealD 3D is a digital stereoscopic projection technology made and sold by RealD. It is currently the most widely used technology for watching 3D films in theaters.[1] Worldwide, RealD 3D is installed in more than 26,500 auditoriums by approximately 1,200 exhibitors in 72 countries as of June 2015.[2]

Technology

[edit]

RealD 3D theater technology is a polarized 3D system that uses circularly polarized light to produce stereoscopic image projection. The advantage of circular polarization over linear polarization is that viewers are able to tilt their head and look about the theater naturally without seeing double or darkened images.[3] However, as with other systems, any significant head tilt will result in incorrect parallax and stop the brain from correctly connecting the stereoscopic images.

The high-resolution, digital cinema grade video projector alternately projects right-eye frames and left-eye frames, switching between them 144 times per second.[3] The projector is either a Texas Instruments Digital Light Processing (DLP) device or Sony's reflective LCOS (liquid crystal on silicon). A push-pull electro-optical liquid crystal modulator called a ZScreen is placed immediately in front of the projector lens to alternately polarize each frame. It circularly polarizes the frames clockwise for the right eye and counter-clockwise for the left eye.[4] The audience wears circularly polarized glasses that have oppositely polarized lenses that ensures each eye sees only its designated frame. In RealD Cinema, each frame is projected three times to reduce flicker, a system called triple flash. The source video is usually produced at 24 frames per second per eye (total 48 frames/s), which may result in subtle ghosting and stuttering on horizontal camera movements. A silver screen is used to maintain the light polarization upon reflection and to reduce reflection loss to counter some of the significant light loss due to polarization filter absorption. The result is a 3D picture that seems to extend behind and in front of the screen itself.[5]

Technology

Core Principles

RealD 3D's core principles are rooted in passive stereoscopic imaging, drawing from inventor Lenny Lipton's pioneering work in the 1980s on electronic stereoscopic displays. Lipton, through his company StereoGraphics Corporation, developed the ZScreen polarization modulator, a liquid crystal-based device that enabled the alternation of polarization states for left- and right-eye images using a single projector. This innovation, patented in 1989, laid the foundation for modern digital single-projector 3D systems by adapting passive polarized 3D technology for efficient, flicker-free projection. The system employs to separate the left-eye and right-eye images, ensuring that each eye receives only its intended perspective without significant or ghosting. Unlike , which can cause image leakage if the viewer's head tilts, circular polarization maintains separation regardless of head orientation, allowing natural movement in the viewing position. Images are alternated at a rate of 144 Hz—72 frames per second per eye—creating the illusion of continuous motion and depth through , where slight horizontal offsets between the paired images mimic human . To preserve the integrity of the polarized light upon reflection, RealD 3D requires specialized silver-coated projection screens, which reflect light while conserving its polarization state. Standard matte screens scatter and depolarize incoming light, leading to reduced contrast and increased ghosting in stereoscopic viewing, whereas the metallic coating of silver screens minimizes this , maintaining high image fidelity across the .

System Components

The RealD 3D system relies on a core hardware component known as the Z-Screen, a push-pull electro-optical modulator positioned directly in front of the projector's lens. This device rapidly alternates the polarization of projected between left-eye (counterclockwise circular) and right-eye (clockwise circular) images, enabling the delivery of separate stereoscopic views from a single digital at frame rates up to 144 frames per second (72 per eye) to minimize flicker and ghosting. Integral to the viewing experience are the RealD 3D , which feature circular polarizing filters—one lens clockwise for the right eye and the other counterclockwise for the left—to selectively transmit the corresponding polarized images while blocking . These incorporate anti-reflective coatings on the lenses to enhance clarity, reduce glare, and improve comfort during extended viewing, along with low-glare frames designed for a wide . The system integrates seamlessly with high-frame-rate projectors, including both traditional xenon lamp-based models and modern projectors, which provide the necessary and color accuracy for . For optimal performance, RealD 3D requires a specialized embedded with metallic particles to preserve polarization and reflectivity, counteracting light loss from the filters and ensuring high stereo contrast—though newer iterations like the RealD Ultimate Screen offer 75% brighter images and 10 times better contrast than traditional silver screens. Later developments in RealD 3D glasses emphasize eco-friendliness through lightweight, recyclable materials suitable for mass distribution, with RealD annually providing approximately 18 million pairs in the US and Canada while implementing collection programs to recycle returned units and reduce environmental impact.
