Description
A Fresnel ALR Electric Projector Screen is a high-performance optical screen designed for use in environments with ambient light.Unlike conventional projection screens that scatter light in all directions, this screen utilizes a specially engineered micro-structured optical surface—primarily based on a Fresnel lens—to manage light directionally.It selectively reflects the projection light from the projector towards the viewers while absorbing or rejecting ambient light from other sources.The electric mechanism allows for convenient retraction and deployment,making it a versatile and user-friendly solution for both home and commercial applications where achieving a high-contrast image in non-darkened conditions is essential.
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 (ALR)
Drastically reduces the impact of ambient light from ceiling lights and windows, enabling daytime viewing and flexible room lighting.
High Contrast and Color Saturation
Preserves the projector’s native contrast ratio and color integrity, delivering images with deeper blacks and more vibrant colors.
Electric Retractable Mechanism
Quiet electric motor rolls the screen into a compact casing when not in use, offering a sleek, space-saving solution
Rigid, Flat Surface
Fresnel lens layer adds structural rigidity and tension system,maintaining a perfectly flat surface to prevent waves and distortions.
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.
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. |
Electric screen details
Fresnel ALR Electric Projector Screen
The CynthiaScreen Fresnel ALR Electric Projector Screen redefines the home cinema and professional presentation experience. Engineered with cutting-edge optical technology, this screen empowers you to enjoy stunningly bright, high-contrast images without the inconvenience of a darkened room. Its sleek, electric design integrates seamlessly into your living room, boardroom, or media room, offering both superior performance and elegant convenience.
At the heart of this screen is a multi-layer optical film featuring a precision-engineered Fresnel lens and a vertical lenticular layer. This sophisticated system works in harmony to actively reject ambient light from overhead and side sources, such as ceiling fixtures and windows. By channeling your projector’s light directly to the audience and absorbing disruptive ambient light, it delivers exceptional black levels, vibrant color saturation, and crystal-clear detail that rivals a traditional TV.
Featuring a whisper-quiet, remote-controlled electric motor, the screen gracefully descends from its minimalist aluminum housing for movie night and retracts discreetly when not in use. The robust casing protects the delicate screen surface from dust and damage. The surface itself is protected by a scratch-resistant anti-glare coating, ensuring long-lasting performance and easy maintenance.
Whether you are building a dedicated home theater, upgrading your living room entertainment hub, or equipping a professional conference room,CynthiaScreen is the perfect choice. It unlocks the full potential of your UST projector, transforming any space into a dynamic and immersive viewing environment.
