How do 3D movie projectors work

Movie projectors are nothing new to us. A good home movie projector can allow us to watch a movie in a bigger screen at home. Instead of playing the movie on a digital screen, a movie projector can project the picture on a special wall so that you can have a better view of it. we are all familiar with regular movie projectors, but what about 3D movie projectors? As its name suggests, 3D movie projector can project 3D images and pictures on the wall, and that would bring a much experience for us when watching a 3D movie. But how do 3d movie projectors work? Why would it present a 3D picture? Let's find out together.

Part 1: History of 3D movie projectors

As surprising as it may sounds, but 3D movies may be around since the early 1900s. However, 3D-ready home theater projectors didn't enter the market until 2008, And those 3D movie projectors were only designed mainly for educational purposes. These early model 3D projectors only had a resolution of 720p, and since they didn't have an HDMI input, they could only receive content from a PC through a VGA or DVI cable, reducing the image quality to an acceptable, but not great level, 480i.

For 3D movie projectors, everything changed in 2010 with the release of the LG CF3D, the first 1080p 3D projector for home theater. The LG CF3D was the first 1080p 3D projector with HDMI inputs, meaning it could process signals from 3D-ready Blu-rays and the PS3. The LG CF3D 3D projector could also handle multiple 3D formats, including frame sequential, side-by-side and checker board.

Since 2011, we've seen host of new HD 3D projectors, including projectors that can convert 2D content to 3D. Results vary from meh to pretty ok, depending on what's actually being projected, but from our experience, native 3D content will always look better.

To "see" in 3D, a slightly different image must be altered to be delivered to each eye. This is traditionally done with special glasses. To your brain, these overlapping images create the illusion of depth.

Many of today's cinematic 3D experiences are delivered via polarizing systems. These send the projector's light through polarizing filters that force the light waves to oscillate in two different directions, one intended for the left eye, the other for the right. A special polarization preserving screen is required. Filters on the glasses allow the lenses to passively pick up the light (read: image) meant for each eye. The brain combines the two images and then, 3D.

As of right now, all the 3D-ready projectors available in the commercial and residential market use active shutter glasses to deliver the third dimension. This will likely remain the standard for all 3D DLP projectors in the future.

In this setup, the image on the screen alternates rapidly between scenes intended for each eye. The glasses respond by opening and closing the corresponding lens. So far, all 3D DLP projectors use the DLPLink protocol to sync the glasses and the screen. We predict this setup, in which a white light is beamed from the projector to the screen to the glasses, will become the standard for 3D projection.

Part 3: Best player software for 3D movie projectors

Now we have solved the problem if how do 3d movie projectors work. Despite using a 3D movie projector can bring us the ultimate viewing experience for 3D movies, a media player on the computer end, however, is also as important as the projector. Because if your media player can decide how the movie be presented in the end. If your media player cannot handle a 3D movie very well and plays the movie very choppy and laggy, there is really not much a good 3D movie projector can do to improve your experience. That's why I am here to recommend a good media player for your 3D movie enjoyment, and this player I would recommend, is called Leawo Blu-ray Player.

As a 100% free DVD/Blu-ray player, Leawo Blu-ray Player can play all forms of DVD or Blu-ray materials including folders, ISO files and optical discs. all of these Blu-ray/DVD materials can be played in the original quality. What's more, this player can handle 3D movies very well, so that it could provide a stable stream for your 3D movie projector and ensure you to have the best watching experience with your 3D movies.

Besides playing DVD/Blu-ray materials, Leawo Blu-ray Player can also play all kinds of digital video files like MP4, WMV, MKV and so on. With some optimized options like subtitles, video settings and audio settings, you can set almost every parameter of the video playback according to your playing environment and your personal needs.

Conclusion

Today were talked about how do 3D movie projectors work. 3D movie projector is an amazing invention, it can bring us the ultimate 3D movie enjoyment at home, under one condition, having a good media player. Leawo Blu-ray Player is the best match for a good 3D movie projector. Having these two teamed up, I believe you will have an amazing 3D movie experience.
