DLP TM System and 3D Glasses with high-speed liquid -crystal shutter for Overwhelming 3D Performance
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 (minimum judder) and luminance (brightness maintained).
Minimal Crosstalk
DLP elements and the high-speed shutter of our
TM
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.

Brightness Maintained
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.

3D Glasses with high-speed
liquid-crystal shutter (optional)
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.
Portion where the color wheel is
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.
