How Do ALR Screens Work?ĪLR screens selectively reflect light the projector’s light is reflected on the screen and back to the audience. So, ALR screens are the cheaper, versatile, and definitely better solution to the problem of ambient light. However, compared to the cost of simply buying an ALR screen to use with any projector, projectors with that level of luminosity are extremely expensive. One way to avoid the problem caused by ambient light is to buy extremely powerful projectors that are able to provide extremely high levels of luminosity or brightness. It does so by weakening the light coming from the projector, thereby reducing the picture quality on the screen. ![]() ALR screens are a result of a special material that enables them to reflect light selectively.Īmbient light impacts the quality of a picture a projector can produce. As the name suggests, ALR screens reject ambient light, which is simply all other light sources in a room apart from the projector light. What Are ALR Screens?ĪLR stands for Ambient Light Rejecting screens. This is where ALR screens come in. Yes, I am talking about Ambient Light Rejecting Projector Screens (ALR). Therefore, in order to use a projector and screen in daylight, a solution to the problem of lighting must be found. It is hard to blot out all light even in the dark, it will be almost impossible to block out light in daylight completely. You must block all the light sources, and every ray blotted out so that the lighting does not interfere with the light from the projector and the picture on the screen. Using a projector even at night requires a pitch dark room so that no other source of light interferes with the light from the projector. ![]() ![]() However, here’s another thought: how about trying to recreate the cinema feel in your home in daylight? I am sure the first problem that comes to the mind of anyone who has used a projector screen is light. A projector and a screen, then wait for nighttime and grab some popcorn – great, right? Have you ever thought about recreating the whole cinema feel but at your house? If you have, then you likely turned to projectors and a screen to create that lights out, cameras roll aura within the confines of your own home.
