Description
Fresnel ALR Narrow Frame Screen
Premium optical projection screen designed for ultra-short-throw/standard projectors and laser TVs, delivering exceptional image quality even in brightly lit environments.
The Fresnel ALR (Ambient Light Rejecting) Narrow Frame Screen represents the pinnacle of projection technology, engineered specifically for ultra-short-throw projectors and laser TV systems. Also has models in standard throw projector.This premium screen utilizes advanced micro-optical structures to deliver stunning image clarity, vibrant colors, and deep contrasts even in well-lit rooms.
Fresnel ALR Screen Fabric
- Structure: Features semi-concentric circular grooves (similar to a flattened concave mirror). These grooves not only reflect light from the projector lens aligned with the center of the circles.while absorbing stray light from above and the sides.
- Principle: Uses Fresnel lens-like focusing properties to concentrate projected light into a narrow viewing zone,enhancing brightness and ambient light rejection.
- Superior Ambient Light Rejection: ~96% rejection rate; significantly better performance in bright environments.
- High Brightness Gain: Up to 1.8x(±0.2) brightness boost due to light-focusing design, delivering sharper images.Viewing angle within 120°.
- Enhanced Image Quality: Supports true 8K resolution; richer colors and depth closer to OLED TV quality.
- Premium UST projector screen,also premium standard throw projector screen.Optimized for UST and Standard Throw Projectors:Fresnel screens work well with both ultra short throw projectors and standard throw projectors.
- Best used for High-ambient-light rooms, corporate settings,home theater,living rooms,offices etc.
Superior Ambient Light Rejection
Advanced Fresnel technology blocks ambient light from above and sides, allowing for clear viewing even in brightly lit environments without compromising image quality.
Enhanced Color & Contrast
High gain value (1.8±0.2) combined with multi-layer optical films delivers richer colors, deeper blacks, and superior contrast compared to standard screens.Support 8K images.
Wide Viewing Angle
Enjoy consistent image quality from virtually any position in the room with an impressive 120° viewing angle, perfect for group viewing.
Sleek Aesthetic Design
The ultra-narrow 1cm aluminum frame provides a modern, minimalist look that complements any interior design while maximizing viewable area.
Structural Composition
The screen is a marvel of optical engineering, typically composed of multiple, precisely engineered layers. The following table outlines the common structure of an 8-layer Fresnel screen:
| Layer | Function |
|---|---|
| Holographic Light Shaping Layer | Controls the direction and spread of the projected light for uniform brightness. |
| Transparent Flexible Layer | Provides a flexible base for the optical structure. |
| Eye Protection & Anti-Violet Layer | Filters out harmful blue/violet light to reduce eye strain. |
| Color Calibration Layer | Ensures accurate and vibrant color reproduction. |
| Fresnel Prism Layer | The core layer featuring concentric circular ridges that manage light reflection and rejection. |
| Nano Absorption Layer | Absorbs ambient light from the environment to improve contrast. |
| Image Quality Enhancement Layer | Further refines picture clarity and detail. |
| Plasma Reflection Layer | Efficiently reflects the projector’s light back towards the viewer. |
Light resistance performance comparison
How It Works
The Fresnel prism layer, with its concentric circular micro-structures, is engineered to be highly sensitive to the specific angle of incoming projected light from ultra-short-throw projectors. It efficiently collects and reflects this light directly back to viewers.
Simultaneously, the nano absorption layer neutralizes ambient light from ceiling lights or windows by absorbing it rather than reflecting it. This prevents ambient light from washing out the projected image, maintaining deep blacks and high contrast.
Standard Screen
Reflects both projector light and ambient light equally, causing washed-out images in bright conditions.
Fresnel ALR Screen
Selectively reflects projector light while absorbing ambient light, maintaining image quality even in bright rooms.
