UST Motorized Floor Rising Screen
Elevate Your Vision — Where Light Meets Precision
An UST Motorized Floor Rising Screen is a high-end projection screen specifically engineered for ultra-short throw laser projectors or laser TVs. It is designed to be placed on a TV console or directly on the floor, rising electrically when in use and retracting seamlessly into a sleek base when not needed. Its core feature is the integrated ambient light rejecting (ALR/CBSP) Black Grating optical material, which utilizes a micro-prism “black grid” optical structure. This technology significantly combats ambient light from above, enabling bright, vivid, and high-contrast viewing even in well-lit environments. It is an ideal solution for modern home theaters and commercial spaces seeking a large-screen, television-like experience without permanent installation.

Ultra-Short Throw (UST) Optimization
It is engineered with a specific optical coating and microstructure ( black grid) that is precision-angled to optimally reflect the steep, upward-angled light beam from a UST projector placed just inches below or in front of the screen. This ensures uniform brightness, color accuracy, and minimizes hotspots.
How it works
- Structure: The screen surface uses a horizontal sawtooth prism structure composed of alternating black and white layers. The white angled surfaces reflect light from the projector (positioned below), while the black layers absorb ambient light from above and the sides.
- Principle: Selectively reflects projector light while blocking ambient light through directional absorption
- The physical black grid structure is the key to its performance. The white slanted surface reflects the image from the projector (placed below the screen) directly to the viewers, while the black parallel layer absorbs ambient light coming from above. This dramatically improves contrast and color saturation, making it possible to watch content without needing to turn off lights or close curtains
- Optimized for Ultra-Short Throw Projectors: This screen is exclusively designed for laser TVs and ultra-short throw projectors placed on a tabletop or floor. The optical coating is precisely calibrated for the steep projection angle of these devices, ensuring optimal image fidelity and sharpness
- Wider Viewing Angle: Up to 170° horizontally, ideal for group viewing.
- Superior Ambient Light Rejection:These screens significantly reduce the impact of ceiling-mounted lights.Ensuring a clear and vibrant image even in well-lit rooms.
- Premium UST projector screen,Ideal for UST (Ultra Short Throw) Projectors
- Moderate Ambient Light Rejection: ~90% ambient light rejection;


Sit Anywhere, See Everything. With 170° Ultra-Wide Viewing Angle, Our Black Grid ALR Floor-Rising Screen Delivers Vivid, Anti-Gloss Perfection From Every Seat.
The exceptional 170° viewing angle is made possible by the advanced micro-structured optical layer of the Black Grid ALR (Ambient Light Rejecting) material. This precision-engineered surface consists of tiny prism-like grooves that direct projected light toward the audience while absorbing and dispersing ambient light from other directions. Unlike conventional screens that scatter light broadly, this controlled reflection ensures consistent brightness, contrast, and color accuracy even at extreme side angles. Combined with a 0.6 gain, low-dispersion design, the screen maintains image integrity across nearly every vantage point—making it ideal for wide rooms, curved seating, or spaces where viewers are not centered. Simply put: it’s not just a screen, it’s a calculated optical system.

The Role of 0.6 Gain: Gain measures how much a screen reflects light compared to a standard white surface. A 0.6 gain means it reflects less total light than a white wall.
Why this is a benefit for contrast: By reflecting less of the ambient light (which is scattered in all directions) and being optimized to reflect the projector's light efficiently, the screen creates a massive difference between the brightest parts of the image (the projector's light) and the darkest parts (where ambient light is absorbed). This difference is the essence of high contrast. The lower gain prevents highlights from becoming overly bright and "hot," ensuring a balanced, natural, and cinematic image with incredible shadow detail.

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.
