UST Floor Rising Projection Screen, mean a floor-rising (motorized or retractable) screen designed for ultra-short-throw (UST) projectors, often with Ambient Light Rejecting (ALR) or Ultra-Short-Throw CLR materials. These screens rise from the floor (or base cabinet) and retract when not in use.

Key Benefits

  1. Ambient Light Rejection (ALR / CLR)
    These screens are designed to reject overhead or side light (ceiling lights, windows, etc.), which means the image remains vivid even in a bright room. Scenes appear clearer, glare and washed-out spots are reduced.

  2. Better Contrast and Black Levels
    By absorbing or redirecting unwanted light, these screens enhance perceived black levels. Dark scenes look richer and more cinematic rather than faded out.

  3. Optimised for UST Projectors
    UST projectors have a steep throw angle (they sit very close to the screen). Regular screens or walls may reflect much of the image poorly or allow stray light scatter. UST ALR/CLR screens are engineered (optical surface / lenticular / micro-sawtooth etc.) to work well with that angle, giving more uniform brightness and less distortion.

  4. Space Saving & Aesthetics
    Because they rise from the floor (or hide when not in use), they don’t require permanent wall-mounting or large ceiling structures. This can make the room look cleaner, less cluttered, more flexible. For example, when you’re not projecting you have just a sleek base or floor unit rather than a screen covering your wall.

  5. Flexibility & Minimal Installation Impact
    Floor-rising units often avoid needing to drill into your walls or ceilings. Also good for rooms where wall

  6. Automatic Deployment / Convenience
    Motorized models offer push-button or triggered rise/drop. Makes usage easy; you don’t have to manually fix a screen every time. This also helps protect the screen (keeping it retracted when not in use).

  7. Protection of the Screen When Not in Use
    Retractable or floor-rising designs protect the screen fabric (from dust, accidental damage, light exposure) by having it stored when not in use. This can increase longevity.

  8. Sharp / Clean Image (Flatness, Tensioning)
    Many of these screens come with tab-tension or cross spring tensioning, to ensure the screen remains flat. A flat screen is especially important for UST systems because slight imperfections or curl in the screen are very visible (due to the low angle of projection).
