Everyone knows that now projectors are becoming more and more easily accepted by people. With the maturity of projectors, the trend of buying projectors from house to house is also increasing. If we gossip, we will say nothing. Double investment plan. Of course, if you are already a big bully, don’t despise me.
Currently there are 3 options for watching 3D movies:
Shutter type 3D projector
2. Polarized 3D projector
3. Hand-made people to build double-project
First, let us introduce shutter 3D projection technology and polarized 3D projection technology:
I believe we can find out if these two kinds of technologies are good or bad through the pictures. I will not elaborate on them here.
Speaking of double-throwing, this is a key point today. Some 3D movie lovers will buy two projectors to build a double-projection scheme. The benefit is that brightness and contrast saturation are not impaired, and building double-throwing is very The troublesome thing, and the equipment that can be played is relatively single, can only be realized through the computer.
In fact, why did I toss this? It was because my friend was preparing to get a small movie theater in the county. In order to help him, I was also tossing and finally found the 3D polarizer on the Internet.
Simply look at the appearance of it:
The appearance of the converter is very simple, white color, faintly visible 3D words, but there are a lot of bees, does this heat really explode? The design is also very simple, even the LOGO is reluctant to paste one up.
Take a look at the official introduction:
The conversion box is designed for two-projector-built polarized dual-projection systems to solve the problem of polarizing dual-projection non-computer unable to play 3D movies, free from cumbersome software program settings, and easy to implement Blu-ray players, hard disk players, PS3 game consoles, CCTV 3D Channels and other equipment that can only output one channel of 3D signal are docked with polarized double projectors.
The accessories are very simple, with only one power supply and one remote control.
Look at the input ports: Power, USB, HDMI*2, VGA, and AV and audio interfaces, respectively.
Two HDMI connectors at the output.
The nameplate is on the back, it seems I'm wrong with him
The surface of the remote control is still very fine, and the matte process is obvious. The feel of the buttons is much better than that of the TV remote control. The sense of confirmation is full.
General installation plan diagram:
Another disadvantage of doing double-throwing is that you must purchase 3D metal curtains, so as to achieve a good viewing effect. As for the process of setting up a friend, it has not been photographed. It is a little troublesome anyway.
Then this is the result of a friend's final achievement:
In the end, the advantages of the dual-projection polarized 3D solution are its high brightness, strong 3D sense, and low price of 3D glasses. The disadvantages are high cost of the dual-system, difficulty in commissioning and installation, and the need for metal screens to achieve the desired results.
