3D Glasses with high-speed liquid-crystal shutter
Amazing reduction in peculiar phenomena during 3D viewing
Mitsubishi Electric has developed original 3D Glasses with high-speed liquid-crystal shutter that best match
the high-speed response of elements in the DLP
a minimum. Additionally, an ultrahigh-speed response feature is incorporated, realizing unprecedented high-quality
3D imagery. The HC7800D allows you to truly relax and fully enjoy 3D content with overwhelming sharpness
(minimal crosstalk), high definition (minimal judder) and luminance (brightness maintained).
DLP TM elements and the high-speed shutter of our
newly developed 3D glasses work together to produce
sharp images by minimizing image crosstalk between
the right and left eyes.

- Built-in high-precision
conversion feature
Thanks to motion-vector analysis technology,
the position of a person can be distinguished
from the background and a moderate parallax
added to produce the sensation of depth
used in 3D images. Unlike simple 2D-to-3D
conversion where the entire screen is shifted,
3D images with a natural sensation of depth
are reproduced, making it possible to bring
even classic films back to life in vivid 3D.

Combined with a 3D-compatible fame rate converter
(FRC), high-definition images with nominal image lag
are achieved.

Positions of person and background are 3D image with natural depth sensation
detected, and a moderate parallax is added
The high-speed opening/closing operation of
the shutters in the newly developed 3D glasses results
in remarkable brightness by suppressing
the loss of luminance.

The high-speed shutter of the newly developed 3D glasses
shortens the blanking (black signal) when switching images
between right and left eyes, resulting in flicker-free images.
Newly developed liquid-crystal shutter enables extremely high-speed response, but
is sensitive to shock compared to conventional TN liquid-crystal. Accordingly,
glasses frames are designed thicker in consideration of protection.

joined is used for blanking.
High-speed switching over 10 times
faster than TN liquid-crystal shutter
glasses reduces blanking to 1/20,
realizing amazingly little eye fatigue.
