  2. RealD 3D - Wikipedia

    en.wikipedia.org/wiki/RealD_3D

    RealD 3D cinema 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 ]

    en.wikipedia.org/wiki/Liquid_light_show

    Light from a liquid light show, being projected behind a guitarist Layers of colored mineral oil and alcohol move over the projector lens and produce changing color patterns. Liquid light shows (or psychedelic light shows ) [ not verified in body ] are a form of light art that surfaced in the early 1960s as accompaniment to electronic music and ...

  4. ZScreen - Wikipedia

    en.wikipedia.org/wiki/ZScreen

    ZScreen is a push-pull electro-optical liquid crystal modulator that is placed immediately in front of the projector lens or computer screen to alternately polarize the light from each video frame. It circularly polarizes the frames clockwise for the right eye and counterclockwise for the left eye.

    en.wikipedia.org/wiki/Active_shutter_3D_system

    Many projectors, especially DLP-based ones, support 3D out of the box. LC shutter glasses are shutting out light half of the time; moreover, they let only 50% of light through when open, because they are polarized. This gives an effect more profound than watching TV with sunglasses on, which causes a picture at only 1/4 brightness to be ...

    The light source is used to provide the necessary illumination for the LCos panel. The most common light source used in LCos display systems is a high-intensity lamp. This lamp emits a broad spectrum of light that is filtered through a color wheel or other optical components to provide the necessary color gamut for the display system.

  8. Spatial light modulator - Wikipedia

    en.wikipedia.org/wiki/Spatial_light_modulator

    The image on an optically addressed spatial light modulator, also known as a light valve, is created and changed by shining light encoded with an image on its front or back surface. A photosensor allows the OASLM to sense the brightness of each pixel and replicate the image using liquid crystals. As long as the OASLM is powered, the image is ...

  9. LCD projector - Wikipedia

    en.wikipedia.org/wiki/LCD_projector

    It is a modern equivalent of the slide projector or overhead projector. To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon panels – one each for the red, green and blue components of the video signal ...
