Until now, IRTC has assembled more than 160 3D cinemas across Vietnam cities and provinces by the most modern and satified more and more entertained requestment of audiences.

The 3D film system is currently being installed using two technologies: DLP technology and polarization technology.

1. Install 3D movie theater system 3D polarization Real D (2 projectors)
  
    3D polarization technology uses passive polarizers and non - depolarization silver - screen and dual - projector projectors. This is the most advanced and qualitied technology today, used in most commercial 3D cinema in the world.
   The general principle of the system is that the input data of the 3D projector is stereo image data consisting of two streams of images (left and right). Through a dedicated 3D graphics card, stereo images output two synchronized projectors, each with a separate data stream. Since the light emitted by each projector is polarized, in two directions perpendicular to each other, so when wearing passive polarizer glasses to separate left images for left eye, right image for right eye, will get the 3D effect is expressed very clearly

    The system includes equipment:

• 02 projectors with the same model (to create the best picture sync), should use the high brightness projectors (from 2500 Ansi lumens or more).
  
• 01 computer cotaining HD - 3D playback source
  
• 01 mornitoring screen is placed in the technical room to creat professional presentation.
  
• 01 màn chiếu bạc: The silver screen is used to increase the brightness of the image . MThe silver screen also supports better polarized images, minimizing ghosting effects, and support for 3D effects( 02 Linear or Circulur filters); Pass through two filters to create a polarized image
• Suitable glass for Filter (optional): Filter Linear use 3D linear, Circular Filter uses Circular Glass 3D.
• The bracket for positioning two projectors, hanging upside-down adjustable eight directions for optimal 3D images
• Signal cables and other peripherals: HDMI, VGA, Optical cable, Coaxial cable depending on the line and requirements.
• Storage devices: Western HDD, Seagate HDD, Samsung HDD (500GB, 1TB, 1.5TN, 2TB, 3TB, ...)
• Sound system (stereo or normal sound depending on demand)

2.  3D projector technology - DLP active (shutter)

    In 2007, Texas Instruments introduced a DLP display system that takes advantage of the speed of digital micro-mirror device (DMD) - to generate a high refresh rate ( high refresh rate that meets the requirement of stereoscopic presentation.

      DLP technology is also incorporated into the projector system with the introduction of DLP 3D projection screen technology using a shutter glass or 3D shutter using a DLP projector.

      The system includes equipment:

• 01 projector
  
•  DLP Shutter Glass: is a glass used in conjunction with a display to create the illusion of a 3D image. Each of its lenses contains a layer of crystalline crystals, which will darken to prevent light from entering if it is applied to the voltage and vice versa, it will remain transparent if no voltage is present.
  
• Dedicated  silver screen
  
• Projector mount, projector position, 3D image with the highest floating
  
• Computer and mornitoring screen
  
• Sound system (stereo or normal sound depending on demand)
  
• Storage devices
  
• Signal wire and other peripherals

So, when should you choose to pass 3D passive technology? When should you choose to adopt 3D active technology?

1. Passive 3D movie
   

         Representing the passive 3D movie market is 3D cinema, 4D movies, 5D movies, 6D movies, 7D movies using 02 projectors. The features are:

• The new lightweight, non-battery-powered 3D glass lens, elegant design and super-economical price will give you the ultimate 3D visual experience.
• Offering stunning 3D video quality without sacrificing eye fatigue thanks to the ultimate image shake / blur reduction technology, the image details are fully rendered & sharp in 3D movie space with the feel extremely pleasant to the eyes
• Should only be applied to a room from 10 viewers, it will save money

       2. Active 3D movie

         Representing the 3D film market is active home theater, 4D movie room, 5D film, 6D film, 7D film using a projector. Characteristics:

•  Batteries should be heavy and bulky, so high cost will be expensive if broken, glass may not work well when the battery is weak. In addition, in hot and humid Vietnam, the electronic circuit on the glass may malfunction.
• Limit the quality of 3D movies by using flicker-induced flicker technology.
  
• It should only be applied to the thorium screening room with the best viewer of 5-6 people and with a small family but still want to enjoy watching the widescreen (for 3D projectors)
