Front Projection vs Rear Projection

front projection vs rear projection

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

Each type of projection has advantages and disadvantages that should be considered before deciding which is perfect for your need.

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

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

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

On the other hand, the rear projection is placed behind the screen. It is mostly used in newsrooms where space is not a problem.

The main advantage of rear projection is it will give brighter images in an ambient condition where it has been placed.

Let’s discuss all the advantages and disadvantages of both the projection system.

Front Projection

The projectors that project the images from the front are placed on table, stand, and even mounted on the ceilings.

These are used 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 the screen. 

Advantages

One thing I always like about the front projection system is that you can project the images from any angle with the help of a screen that reflects the image to the viewer’s eyes.

The Front projection 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. You will find a low-cost front projector with different prices.

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

Disadvantages

1). If the front projection is placed in a classroom or business meeting, the presenter has to move for the information presented on the screen. 

2). Also, if you place it on the ceilings, it is tidy work that requires lots of time to calibrate the right image on the wall.

3). If your projector is removed from the viewing screen, the unit’s brightness will start degrading due to less lamp power projecting on the wall.

4). As the projector is placed in front of the screen, you will see a rainbow effect and lots of glare, making the image difficult to see and can cause eye strain.

Rear Projection

This type of projection system is placed behind the screen, and the viewers will sit on the other side of the screen to see the content.

So, 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 placement, 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 a bigger room 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 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 to project the video as the projection is made from the front side.

But in the case of rear projection, you will need more space 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 must 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 for the right picture quality.

Ambient Lighting

In the case of rear projection, you will need more ambient light to get clear images, helping them to become more visible.

The light should not come from the front screen where viewers are sitting or standing to get clear picture quality.

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 place the front one away from the screen, the brightness level will be degraded compared 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 can project with a front projection system.

Regarding rear projection, it’s impossible to project on a wall or a cheaper screen. You will require a high-gain specialized screen 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 provides 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 powerful projector 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 projection system is perfect in there projection system. If you are looking for a projection system for your house, then the front is ideal.

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