Motorized ALR Floor Rising Screen
Elevate Your Vision — Where Light Meets Precision
A Fresnel motorized ALR floor rising screen (often referred to as a Fresnel motorized floor-rising projection screen) is a high-end, retractable projection screen system designed for premium home theaters or luxury AV installations. It combines advanced optical screen technology with an automated lifting mechanism that rises seamlessly from the floor when needed and retracts out of sight when not in use.










Whats Fresnel ALR Screen?
- A Fresnel ALR (Ambient Light Rejecting) screen is a high-performance projection screen designed to deliver bright, high-contrast images even in well-lit environments. It uses a specialized optical structure based on the Fresnel lens principle, combined with micro-louver or angular reflective technology, to selectively reflect light from the projector while rejecting ambient light coming from above, below, or the sides.
What Size does this Fresnel ALR screen have?
- We can provide Fresnel ALR motorized floor rising screen in size 80″,84″,92″,100″,106",110″ , 120″,133″,150″.
Can I customize screen size?
- Yes, you can customize the size of the screen, up to a maximum of 150 inches.
What type of projector is this ALR screen used for?
- This Fresnel ambient light rejecting (ALR) motorized floor rising screen is designed for standard-throw projectors and is compatible with both traditional light source and triple-laser projector models.
What size of projection screen should I buy?
| Viewing Distance | Recommended Screen Size (16:9) |
|---|---|
| 2.0 – 2.5 m | ≤ 84 inches |
| 2.5 – 3.0 m | 84 – 100 inches |
| 3.0 – 4.0 m | 100 – 120 inches ✅ (most popular for living rooms) |

| ≥ 5.0 m | 150 inches or large |
Why do I need to use a projection screen? Can't I use a white wall?
- A clean, smooth, matte-finish, truly white wall in a light-controlled room can work reasonably well for casual use. However, for consistent brightness, accurate colors, better contrast, and a professional viewing experience, a dedicated projection screen is strongly recommended.Using a dedicated projection screen offers several important advantages:
Consistent Reflectivity: Projection screens are engineered with uniform surface materials that reflect light evenly, ensuring consistent brightness and color across the entire image. Walls often have texture, paint sheen variations, or subtle discolorations that can distort the picture.
Optimized Gain and Viewing Angle: Screens are designed with specific gain levels and diffusion characteristics to balance brightness and viewing angles. A white wall typically has low and unpredictable gain, which may result in a dimmer or uneven image.
Color Accuracy: High-quality screen materials maintain better color fidelity. Many white paints contain additives or tints (e.g., “off-white” or blue undertones) that can skew colors in your projected image.
Reduced Hotspots and Glare: Projection screens minimize hotspots and ambient light reflections better than most walls, especially glossy or semi-gloss paints.
Professional Appearance: A proper screen provides a clean, framed image with defined borders, enhancing the viewing experience and aesthetic.
