front projection vs rear projection

In the world of projection systems, there are generally two types of projection. One is the front projection while the other is the rear projection.

Each type of projection has its own unique set of advantages and disadvantages that should be considered before making a decision on which system to buy.

So, before you reach its conclusion, it is important to understand the concept of front projection vs rear projection.

Front projection is a type of projection where the projector is placed in front of the screen giving brighter crisper and easy to set up in any location.

This type of projection is mostly used in business presentations, movie theaters, and at home.

Rear projection is placed behind the screen. Rear projection is mostly used in larger events where space is not a problem.

The main advantage of rear projection is it projects brighter images when there are ambient lights present where it has been placed.

So, which one is perfect we have written a detailed guide on front projection vs rear projection with its advantages and disadvantages that will help you in making a more informed decision.

Front Projection

The projectors that project the light from the front are mostly used projection systems which we all see generally in restaurants, rooms, churches, and almost everywhere. 

This type of projection system hits the light on the screen and emits it back to viewers making it visible on either wall or screen. 

Advantages

One thing which I always like about the front projection system is you can project the images from any angle because with the help of a wall or screen it is reflecting the image back to the viewer’s eyes.

The Front projection also does not require any specialized screen system to produce brighter images. Also, you can place them anywhere like on flat surfaces, coffee tables, ceilings, etc.

With the advantages, there are some disadvantages also having a projection from the front which are as follows.

Disadvantages

If the front projection is placed in a classroom or in business meetings then the presenter has to move in order to give information for what is presented on the screen. 

Also, if you are going to place it on the ceilings then it is tidy work and requires lots of time in order to calibrate the right image on the wall.

If you put your projector away from the viewing screen then the brightness of the unit will start degrading due to less lamp power projecting on the wall.

Rear Projection

This type of projection system is placed behind the screen and the viewers will sit on the other side of the screen in order to see the content. So, it means you will not see the projector while sitting on another side.

Advantages

Perfect for those who don’t want the reflection or shadow of the presenter while giving the information to their students or colleagues. 

Also, according to placing it works the same as the front projection system where the short throw projectors display images at a shorter distance.

Disadvantages

In the same way, the long-throw projection requires bigger room in order to display the image of proper size.

But in the rear projection, the light will go at the back to the projection screen which will reflect it back to the viewers sitting on the opposite side.

Also, it requires a special screen like the Alr ones which has higher gain and projects brighter pictures when the rear projector is used on them.

Front projection vs Rear projection

Space

The front projection system does not require much space in order to project the video as the projection is done from the front side.

But in the case of rear projection, you will need more space, in fact, the projector is kept behind the screen and the viewers sit on the other side of the screen.

You will need to place the projector far enough away from the screen so that the image is in focus. The further away the projector is from the screen, the bigger the image will be.

Installation

Rear projection systems can be more difficult to install than front projection systems. This is because you need to place the projector in the right position behind the screen. If the projector is not placed correctly, the image will be out of focus.

Front projection systems are easier to install because they can be placed anywhere, but the angle should be in the right direction in order to get the right picture quality.

Ambient Lighting

In the case of rear projection to get higher images you will need a higher ambient light which will help the image to become more visible.

So, in order to get clear picture quality, the light should not come from the front screen where viewers are sitting or standing. It should come from the back where the projector is placed.

But in front projection, if there is too much lighting in the room then it can cause the image to be dimmed or washed out.

Brightness

Both the projection front and rear produce the same brightness according to the lumen’s power in the bulb. But if you do the projection away from the screen then the brightness level will be degraded in comparison to that projected near the wall or screen.

Screen

Now the front projection can be used on walls or even on a cheaper screen as the projector lamp is capable of projecting with a front projection system.

Whereas in terms of rear projection it’s impossible to project on a wall or cheaper screen. For that, you will require high grain specialized screen in order to get clear and brighter pictures.

Faq

How much space do I need for a rear-projection system?

You will need to place the projector far enough away from the screen so that the image is in focus. The further away the projector is from the screen, the bigger the image will be.

Can a rear-projection system provide a better level of image quality than a front projection system?

No, both the projector’s system front and rear provide the same level of picture quality. Even the front projection is even better in providing better picture quality if you have a premium projector system.

Is a rear-projection system more expensive than a front projection system?

Yes, rear projection systems can be more expensive than front projection systems. This is because you need to buy a projector that is powerful enough to project the image onto the screen from a distance.

You also need to buy a screen specialized in the higher grain-like (ALR) that is large enough to accommodate the image.

Conclusion

In my opinion, both the projection system is perfect in there projection system. If you are looking for a projection system for your house then the front is an ideal choice for you.

Same way if you are looking for a projection system in museums, classrooms, or large business gatherings, then the rear projection is an excellent choice for you.
