How to select screen fabric ?

The choice of the projector screen will be surprised by its diversity such as optical characteristics, mechanism difference. By knowing its characteristics, you can choose the screen that suits your purpose.
Firstly, it is roughly divided into a rear type (transparent type) where the projector is placed behind the screen and a front type (front projection type) where projector’s light falling from the front of the screen.

Front type screen

Front projection type screens are often selected in many cases, including movie theaters and others. The front type screen reflects the light received from the projector to the viewer and displays the image. Think about the screen with what we are familiar with. Glossy on the surface, mirror and glossy metal plate etc. will not function as a screen. The image of the projector does not appear and the lens of the projector looks dazzling. Why ?
Meanwhile, drawing paper, cloth, whitish walls, whiteboards, etc. may be unintentionally used as substitutes for the screen. The things that looks white to us reflect a lot of light and it meets the characteristics as a screen.


The optical performance of the screen is largely explained in three types.

Diffusive Type (Matte screen) WG/WF

Drawing paper represents close characteristics. Literally diffusing screen is a screen that uniformly diffuses and reflects the light hitting the screen surface in the direction of the bowl shape of 360 degrees without deviation. For this reason, the screen gain theoretically shows 1 in all directions, actually about 0.9.
This is the basis of all screens, about 80% of the market is this spreading type.

Regression Type (Beads screen) BS

The optical characteristics of road signs are this type of screen. Return the reflected light in the direction in which the light was projected. That is why it is easier for drivers to see signs with their car headlights. It is a screen that made the property of returning light (regression) just like a road sign. Since the light is converged, the screen gain will be as bright as 1.5-3. Watching video in the vicinity of the projector is a way of using this screen's performance. However, please be aware that it will be darker than the diffusive type if the angle of more than 20 to 30 degrees off to the left and right from the projector optical axis. This name is from using fine beads in microns from the manufacturing process,. Another advantage of this screen is that stray light (harmful light) is likewise attributed to the direction in which light comes, thus reducing the impact on the viewer of the image.

Reflective Type (Pearl screen) PP

It becomes this type when a cloudy mirror is regarded as a screen. It is similar to reflecting light on the mirror, because it reflects on the opposite side of the direction of the projected light, it is called reflective type. The reason why it’s called Pearl, it was taken from the name of pearl pigment used on the screen surface. When the projector and viewer are in the relationship between the incident angle side and the reflection angle side, selection of this screen is effective. However, due to the difficulty of maintaining flatness and the improvement of the performance of the projector, it has been almost never selected in recent years.


Special purpose screen

Silver screen SD

It is a screen that falls into a reflective type category, but since it has a large gain with a screen gain of 3 or more, and its viewing angle is extremely narrow, so it is currently mainly used as a screen for 3D. It is a screen suitable for maintaining the polarization state of the two projectors for the right and left eyes of 3D video.

Ultra beads premium white BU201

It is a beads screen as can see from the fabric sign. Because of the use of extremely small beads, the texture of the screen surface is as if it is a mat screen. Gray pigment emphasizes dark areas such as black shadows and gives sharpness to the image. It provides a solid image of projection even if under the condition of you use it in a living theater where the image is influenced by stray light, or when it is used in a bright conference room.

<BU201 is ideal for such an environment>
1. No shading completely, partition-only meeting space, dual use of living and home theater room etc.
2. Such as multipurpose halls and other facilities where set projectors on the floor,.
3. A vertically long conference room, home theater where viewing area (room) is relatively narrow.

Although it has been described separately for several types, please select and decide the type according to the projection environment and conditions of screen usage. We are preparing seven types of OS fabric by diffusive type alone so that better screen fabric can be selected by screen size, budget, picture to be projected etc.
