Rear Projection PVC Fabric is a specialized material designed for displaying images projected from behind the screen. Unlike standard front projection screens that reflect light, rear projection screens transmit light through the material to the viewer on the opposite side.

Main Characteristics

• Transmissive Nature: Its primary characteristic is its ability to transmit light from the projector located behind the screen to the audience in front.
• High Contrast: It excels at maintaining high contrast and color saturation, even in environments with ambient light.
• Viewing Angle: With a 60° viewing angle, it offers a more focused viewing experience ideal for direct audience positioning.
• High Gain: The 1.8 gain provides enhanced brightness, making images appear brighter than standard projection surfaces.

Technical Specifications

• Gain: 1.8 (high brightness)
• Viewing Angle: 60°
• Thickness: Typically ranges from 0.28mm±0.02mm
• Color: Neutral gray or white base for accurate color reproduction

Structure

The fabric features a multi-layer composite structure:

• PVC Base Layer: Provides strength, durability, and stability
• Diffuser Layer: Contains microscopic particles that evenly scatter light
• Front Surface Layer: Protective coating that defines the viewing surface

Main Advantages

• Enhanced Brightness: The 1.8 gain provides significantly brighter images compared to standard rear projection materials.
• Clean Appearance: Projector and cables are hidden behind the screen.
• Immunity to Front Ambient Light: Light on the audience side has minimal impact on image quality.
• No Shadow Interference: Presenters can approach the screen without casting shadows.
• Durability: PVC is robust, flexible, and often flame-retardant.
• Focused Viewing Experience: The 60° viewing angle ensures optimal image quality for audiences positioned directly in front.

Primary Applications

This high-gain fabric is ideal for environments where brightness is prioritized over wide viewing angles:

Considerations

The 60° viewing angle makes this material best suited for applications where the audience is positioned directly in front of the screen. The high gain (1.8) provides excellent brightness but may result in some hotspotting if not properly calibrated.
