Black Pro Screen

Product ID: Black Pro Screen

BPS is one of Probright’s newly developed high performance rear projection screen products. By adding a layer of precision- designed optical microstructure, 3M RPF film, to our Fresnel lens, the interference of ambient light can be reduced effectively. In the same time, it also will be able to maintain the excellent visual contrast.

To keep the high contrast ratio, BPS has a layer of black absorption layer to reduce the non-vertical light from the left side (projector side) and the ambient light from the right side (spectator’s side). Due to the high contrast, the screen looks black without projection of light. This is where the “Black Pro Screen” name comes from.

Comparing to traditional optical structure, the micro lens structure of BPS is much tinier. This is why BPS can meet better resolution request. BPS can not only provide high contrast but also maintaining suitable screen gain value to meet different brightness and viewing angle requirements.

Main Features

◆ High Contrast and High Brightness
   Great visual effect even under high brightness environment

◆ High clearness
    Suitable for all high resolution projectors, such as LCD, DLP, and LCOS

◆ High Viewing Angle

 No matter if it is viewed vertically or horizontally, the viewing angle can reach to full 180 degree. Sharp image can be represented by preventing the interference from the sun.

Operation Mechanism

Concentrating the light beam from projector through glass micro lens structure and black layer, the projection image can be maintained as sharp and fresh without the interference from the bright ambient light.

Structure
BPS rear project screen is consisted of 3 layers of structure.

Black Glass Bead 

Black Glass Bead layer is the one facing the projector. The function is to gather the projection beam from projector. It is constituted from millions of black glass bead. By concentrating the light into one center point, the beam will emit from micro lens to the black absorbing layer.

Ambient Light Absorption Layer

The medium layer is the black absorption layer. The high image contrast can be reached through its capability of ambient light absorption.

Acrylic Acid layer with Glare Proof Surface

Passing through black absorption layer, the projection light reach the Acrylic Acid layer facing the spectator. The light will be projected out to form a visually comfortable image through the glare proof surface to the spectator. With combination of the three layers, the brightness and contrast ratio have been greatly enhanced. No matter it is viewed within bright ambient light, or from the side, the viewing satisfaction can be reached with full color and high resolution.
