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

TM

 system. Brightness is maintained and judder is 

suppressed to 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.

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

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.

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.

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.

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.
