Description

Cynthiascreen tab tension screen Fresnel ALR screen electric projector screen 84 inch 16:9

The key characteristics of Fresnel ALR screen include:

1. Fresnel Lens Structure – Utilizes micro-structured concentric grooves that direct projected light toward viewers while rejecting ambient light from other angles.
2. Ambient Light Rejection – Effectively suppresses 80-90% of ambient light interference through optical filtering, maintaining image clarity in bright environments.
3. High Contrast Preservation – Maintains 5,000:1+ contrast ratios even under 200 lux ambient light through multi-layer optical films and anti-reflection coatings.
4. Narrow Viewing Angle Optimization – Typically 120-160° viewing cone ensures optimal brightness for primary viewers while blocking peripheral light pollution.
5. Directional Brightness Enhancement – Amplifies on-axis luminance by 2-3x compared to standard screens through light collimation.
6. Color Accuracy – Multi-layer optical coatings preserve 95%+ of original color gamut.
7. Environmental Resistance – Humidity-stable (20-90% RH) and temperature-resistant (-20°C to 60°C) polymer substrates.
8. Unique beautiful and high quality white square outer housing,with installation bracket for wall and ceiling installation
9. Controlled by RF or IR remote control,open it just with a key.The smart USB trigger is optional,it can make the screen open when the projector turn on;
