Lens shifting is predominantly found in projectors. It allows adjustment of the displayed picture, without physically repositioning the projector; instead, the lens inside the housing shifts and moves in order to allow the desired adjustment.
3LCD is at teknologi present in projectors. The Light source projects a white light, which is split and divided among 3 chips, each generating an image in a basic color (blue, green and red). The 3 images are then combined in a focusing prism, creating the full-color image, and projected onto the screen.
Projektorteknik – D-ILA
D-ILA (Direct Drive Image Light Amplifier) is a technology compriosed of three individually colored chips (blue, green, and red). The light source is polarized, split, and reflected off of each chip, then focused and magnified through a lens to construct the image projected onto the screen.
Projektorteknik – Laser LED
Projektorteknik – SXRD
Silicon X-tal Reflective Display - SXRD is a proprietary of Sony, similar in design to D-ILA technology. The light is seperated and reflected through 3 liquid crystal panels, each in their own color (blue, green and red). The colors are then combined and focused through a lens, creating the final image.
THX is neither a technology, nor a recording format, but rather a quality assurance standard. A THX-certified movie theater can be expected to deliver an audio/video experience close to what the mixing engineers intended.
Consumer equipment bearing the certification has the same intention as mentioned above, albeit on a smaller scale.
