Projectors have become the next big thing and are frequently spotted in offices, homes, classrooms, and conference and meeting rooms. Here we are going to discuss how the projector screen work and function.
Overall, the working mechanism of projector screens looks simple and comparatively less technical. Giving you a general idea, a bright light passes through a small LCD screen. The light then enters into a lens and a hugely magnified image gets projected onto the wall. You can see more details on this working mechanism by checking out the below-mentioned part of this post. And if any ambiguity still comes into your mind, you can share that with us:
The basic working mechanism of a projector screen
A projector screen functions somewhat similarly in a way like we have LCD screens. If you have got an LCD TV projector, you will see that a very bright light shines all the way through a small LCD screen and then makes its way into a lens. The light throws a huge, magnified image onto the wall, which is basically how a projector screen works.
This respective technology is given the name of LCLV or you can say liquid crystal light valve. Remember that if the projector screen does not work up to the mark or starts to malfunction, the projected image will no longer appear smooth and clear.
A good screen brings a color-neutral surface and preserves brightness, color accuracy, and image quality in the best manner. Furthermore, a good-quality screen produces a satisfying, digital and well-saturated image.
Kinds of projector screens
There are different kinds of projector screens, and here we have penned the basic information on them:
Front Projection Screen
A front projection screen remains to be highly reflective. You can have this screen in a light or dark color; the choice is yours. Note that front projection occurs whenever the object comes in front of a light source. On the other hand, the screen appears in front of the object. The light source ultimately casts a shadow of the respective object directly onto the screen.
Thus, the image that you will spot on the screen is going to be a reflection of the light source coming from the projector. It is better to get a front projection screen in dark color. In this way, you will get improved projection.
This kind of screen promises image clarity and prevents light loss even if you have set up the projector in bright rooms. In addition, a front projection screen is generally coated with materials like titanium dioxide or barium sulfate. At times, it is coated with magnesium carbonate.
Rear Projection Screen
Next, we have the rear projection screen! Here the object image remains visible behind the screen. In other words, images are formed all through the back projection. A rear projection screen promises high clarity and improved contrast. You will notice that the ambient light does not get interfere with the image and manage to maintain the picture quality.
Moreover, the screen remains transparent. Using the rear projection screen with projectors with a high lumen rating is recommended. In this way, even if some brightness gets lost, the image will still manage to appear clear and bright in front of the audience.
Acoustically Transparent Screen
Acoustically transparent screens have become a popular pick nowadays. The catchy part of using this screen is that it comes with front-channel speakers. It means excellent visual and audio quality is promised. It is up to you whether you want to keep the speakers on the right, left, or center.
The viewer perceives and genuinely assumes that the sounds are coming directly from the projector screen; this is amazing! Sound passes through the screen, and the whole watching experience turns out to be cinematic.
Under this category, we have sub two types, and details about them are mentioned below:
The woven projector screen:
It remains more sound transparent than using a perforated screen. Note that such a screen is manufactured on a loom. It is assumed that the usage of a woven material gives firmer and naturally varied spacing to the screen. In addition, this screen allows the sound to pass smoothly and conveniently. The only drawback is that some light will be lost through the holes. This might lead to a double-imaging effect issue.
The perforated projector screen
It is made of PVC material. This screen is packed with very small holes. You will see that the holes are generally 0.3 mm in diameter or even less than that. Through these holes, the sound will be passed.
Pull-Down Projector Screen
The last one is the pull-down projector screen! At times, it is given the name of a retractable screen. You can pull it up into the casing when not in use. This screen is operated with the help of a remote control. Or you can operate it manually, just like window blinds. Rest, this screen remains known for its retractable nature.
So, what’s the bottom line? The working mechanism of a projector screen is quite simple. We have a front projection screen, rear projection screen, pull-down projector screen, acoustically transparent screen, and woven and perforated screen. All of them function and run hassle-freely. Some screens of projectors even have front channel speakers.
We again like to remind you that a projector screen’s basic functionality works this way! A bright light shines through the small LCD screen and makes its way into a lens, and, in the end, throws a hugely magnified image right onto the screen. You can keep tuned and connected with us so we can let you know more about the projector screens. Please let us know which projector screen you prefer and how your experience is.
