Rear fabric projector screen

Types of Rear Fabric Projector Screens

A rear fabric projector screen presents a projected image very differently than a typical front projection screen. The rear screen has an opaque image area and a frame for holding the image in a "screen" format. To create an image on a rear projection screen, the projector must be placed behind the screen, so the screen must allow the projected image to pass through while keeping the image clear for viewing. This can be accomplished in many ways.

There are three main types of rear projector screens:

• Rear-illuminated screens: These screens are typically put together like a light box. They are exquisitely bright and are primarily used for advertising or signage. The screen is kept bright and clear because the projector is set behind the screen. Since the projected image comes through, the image must be vibrant and stay clear while the viewer's eyes adjust.
• Diffusion screens: These screens are typically made of an opaque material that is kept smooth to maintain a clear, sharp image. A matte finish on the material allows the light to spread evenly across the surface, creating a diffused image that can be seen from many different angles. The image from the back of the screen will appear to the viewer without any glare or hotspot forming on the screen, though it will not be as bright as illuminated screens. These are the most common type of rear projector screens found in homes and offices.
• Transparent screens: These screens are made of a transparent material where the projected image can still be seen. The challenge with this screen type is ensuring the projector’s image is bright enough to be seen through the screen while keeping the background visible.

In addition to these three types of screens, there are several other ways to classify rear projection screens, such as their mounts. The different mounting options include:

• Ceiling-mounted: Ceiling-mounted projection screens are installed on the ceiling, which saves space on the floor. They are ideal for rooms with limited floor space or where the screen needs to be out of the way when not in use. Ceiling screens can be manually lowered or retracted, or they can remain fixed in place.
• Wall-mounted: Rear projection screens can be mounted on a wall like a picture frame. Fixed-frame screens have a tensioned screen surface enclosed in a decorative border, ensuring a smooth and wrinkle-free projection surface. Wall-mounted screens are an excellent option for small to medium-sized rooms with minimal ambient light.
• Portable screens: These lightweight and easy-to-transport screens are suitable for various settings, such as classrooms, business meetings, or outdoor events. They typically come with a carrying case for added convenience and can be set up quickly and easily whenever a projector needs to be used.

Functions and Features

Fabric projector screens offer a range of features that cater to users' diverse needs and preferences.

• Materials and Textures:

  Rear fabric projector screens come in various materials, such as matte fabric or vinyl-coated fabrics, for different room environments. Matte fabric absorbs light, reducing glare and providing a soft, diffuse reflection suitable for media rooms or living spaces. On the other hand, vinyl-coated fabrics may have a subtle texture, which helps to diffuse the projected image evenly across the screen surface.

• Screen Ratios and Sizes:

  Just like rigid screens, rear fabric projector screens are available in multiple screen ratios, including 16:9 (widescreen), 4:3 (standard), and 2.35:1 (anamorphic), to accommodate various aspect ratios of projected content. Additionally, they come in different sizes, ranging from small to large, to fit diverse viewing spaces.

• Gain Values:

  The gain value of a rear fabric projector screen measures how much light the fabric reflects compared to a matte white standard. Screens with higher gain values reflect more light, making them suitable for rooms with more ambient light or lower-brightness projectors. Opting for a screen with an appropriate gain value ensures the best contrast and brightness level for the specific projection environment.

• Compatibility with Projector Technology:

  Fabric screens are designed to work well with various projector technologies, including LCD, DLP, and LCoS projectors. They also accommodate different light sources such as lamps, LEDs, and lasers, ensuring optimal image performance for every setup. When selecting a screen for a specific application, it is essential to ensure compatibility with the projector technology to achieve the best results.

• Border Options:

  Some rear fabric projector screens have borders made of velvet or other contrasting materials that enhance perceived picture quality and focus attention on the projected image. The borders also serve to mask the projection beam and improve contrast and clarity.

• Mounting Options:

  Fabric projector screens offer a range of mounting options, including wall mounting for fixed installations, ceiling mounting for discreet integration, and flush mount for a seamless appearance with the surrounding walls. The mounting options allow users to choose the best screen arrangement for their projection environment.

Applications of rear fabric projector screens

Fabric projector screens have lots of applications in businesses, schools, offices, and entertainment areas.

How to Choose Rear Fabric Projector Screens

• Choosing the Right Size:

  A major factor to consider when choosing a rear fabric projector screen is the projector's brightness. Unlike front projection, rear projection requires more screen lumens to achieve a bright image because ambient light can wash out front projections. Hence, screens meant for rear projections are made more reflective to counteract the ambient light flux.

• Screen Surface Texture:

  The texture of a rear fabric screen is another factor to consider when choosing a rear screen. A screen with a perfectly smooth projection surface can offer sharper, more detailed images than one with a textured surface. This is because a textured surface can scatter light unevenly, which can make the projected image appear soft.

• Screen Gain:

  The gain of screen fabric is also an important factor to consider when choosing a rear screen. Gain refers to the amount of reflected light that the screen returns to the viewer. Rear projection screens typically have a higher gain to increase screen brightness to compensate for lower projected light levels due to ambient light.

• Ambient Light Conditions:

  When choosing a rear screen, the ambient light conditions of the room must be considered. In a dark room, a high-gain screen is an ideal choice, while a low-gain screen performs well in a brightly lit room. This is because the room's light will affect the screen's image brightness and color accuracy.
