Do I Need A Special Screen For A 3D Projector?


3D projectors are a higher level of projectors. Greater advancement, and more excitement as well.

Did you just get a 3D projector and wondering if a special screen is required? Read on, and be rest assured that your questions will be answered.

These projectors are getting common in homes, and from time to time the same question is asked; if a special screen is needed for a 3D projector.

Before we dive into whether or not a special screen is required for 3D projectors, let us see what 3D projectors are, and why they are different from regular projectors.

What is a 3D projector?

Slightly different from the regular projectors, 3D projectors make use of specialized technology to produce a three-dimensional image on a two-dimensional surface.

Unlike the regular projectors, a 3D projector allows you to see the depths of images. It brings your viewing to life and makes you feel like the images are real.

Your projector may be 3D-ready or a Full 3D projector. A 3D-ready projector works with the simplest form of 3D which is the frame sequential transmission format. With this type of projector, you will need to add a box to control the shutters on the glasses.

While a Full 3D projector works with all the four transmission formats of a 3D projector. It has a built-in shutter control.

How a 3D projector works?

This projector produces two nearly identical images on the screen simultaneously. It transmits images using four techniques; frame sequential, frame packing, side-by-side, and checkerboard.

There is a need to wear 3D glasses when using a 3D projector. Since the projector sends separate images to each eye, the brain combines the two images into a single image with 3D features. This is where the glasses come in to play.

Although these glasses allow you to enjoy a 3D viewing, they reduce the brightness of the image more because the light has to pass through them to reach the viewers’ eyes. The two types of 3D glasses that you can use are passive polarized 3D glasses and active shutter 3D glasses.

The former is less expensive and has a sleek design. It consists of a lightweight frame and lenses, which allows you to view the same quality image without flickering. However, it makes shapes and text more pronounced, and it reduces the image resolution to about half.

While the latter is designed to sync with the rapidly changing images on your screen. It is powered by a battery, and it can translate data signals with the use of a transmitter. However, it might be uncomfortable because of its bulkiness and the increased speed from the rapid shutter.

Although 3D projectors are a different projector-type, they do not require a special screen. It won’t be out of place to think that for such types of projectors, one should need a special screen. Luckily, a new projector screen is not necessary.

You may use the regular projector screens that are available online. However, to improve the image brightness, you may have to use certain types of projector screens. Note that this is not a must, you don’t need to get one if you don’t want to.

For a standard 3D projector, you can use a high gain screen instead of a regular screen. The gain is the amount of light that the screen ends up reflecting compared to the reference uniform surface.

The main benefit of using a high gain screen is to get increased brightness. The screen reflects light in a narrow pattern, thus increasing the image brightness.

On the other hand, if you are using a dual 3D projector, you may need a polarized screen to optimize your viewing. A dual 3D projector projects two images. It is like having two projectors in one. Each projection lens projects an image, and both images are interpreted by the left and right eye.

3D projectors cause polarization, and since a dual 3D projector is some sort of combination of two 3D projectors, the polarization tends to be higher. To compensate for this, you need a special screen for this type of projectors.

These screens also have high gain, and they help to improve the image brightness which is usually diminished in 3D projectors.

Conclusion

It is exciting to use a 3D projector. Either to watch movies or play games, it serves well. Recently, more movies are made in 3D formats, and you don’t want to miss out on the fun.

Although these projectors have a ton of advantages, they have their flaws. They are expansive and somewhat technical. For a newbie, you may find it difficult to optimize its usage.

If you have invested in a 3D projector, it may not be too much to do the same for a projector screen. Although it is only necessary if you are looking to get a high-gain projector screen, or if you have purchased a dual 3D projector.

However, if you are okay with the regular projector screen, you can save yourself the extra cost of purchasing a high gain model.
