Overview:
1.Q:What are the features of the Mi Ambient Light Rejecting Projector Screen 100?
A: Mi Ambient Light Rejecting Projector Screen 100 is a professional light-resistant screen for use with ultra-short-throw projection equipment. The screen doesn't require any cables to be connected, giving you an unprecedentedly pure visual experience. The 100" giant screen with 8mm metal bezel gives a near borderless visual effect, allowing a full picture to be presented.

2.Q: What is the principle of the Mi Ambient Light Rejecting Projector Screen 100?
A: Mi Ambient Light Rejecting Projector Screen 100 is a hard screen with a Fresnel optical structure. The Fresnel screen is based on the principle of light on one side and absorption on the other side. The surface of the Fresnel screen is structured in concentric circles from large to small to block light from the top of the screen and from the left and right sides, which means that it can block all light from outside the direction of projection, making it more resistant to light and brighter than other screens.
The structure is shown in the diagram:
 
This texture blocks the light from the left and right sides and concentrates the light in the middle, increasing the brightness, but also causing the viewing angle of the Fresnel screen to be worse. (The viewing angle is approximately 160°.) Furthermore, it can only be made into a hard screen that cannot be folded.
The eight-layer structure is shown in the diagram:
 
 
Frequent ask question:
1. Q: Can Mi Ambient Light Rejecting Projector Screen 100 be used independently?
A: Mi Ambient Light Rejecting Projector Screen 100 is a hard screen that doesn't require any power to be applied to the screen, it can be used independently and doesn't have any interface to be used with other devices.

2.Q: What types of projection devices does the Mi Ambient Light Rejecting Projector Screen 100 support?
A: It supports ultra-short focal length projection devices (projection ratio between 0.225:1 ~ 0.275:1), medium and long focal length projectors are not supported. Medium and long focal length projectors are not supported (Reason: Because the Fresnel optical structure is designed for ultra-short focal length projectors, if you use a medium or long focal length projector to project onto a light resistant screen, the projected image will be reflected by the optical structure of the light resistant screen, showing a reflective effect and cannot be viewed normally).

3.Q: What material is the Mi Ambient Light Rejecting Projector Screen 100 made of?
A: Mi Ambient Light Rejecting Projector Screen 100 is made of metal frame, polymer resin (containing multi-layer optical structure and nano-particles) and structural aluminium plate.

4.Q: What is the operating environment for the Mi Ambient Light Rejecting Projector Screen 100?
A: Indoor use, temperature: 25 degrees ± 10 degrees, humidity: 50 ± 20% RH.
Mi Ambient Light Rejecting Projector Screen 100 is an optical screen that contains a multi-layer optical structure and nano-particles, which can effectively absorb ambient light and greatly enhance the contrast and colour saturation of the display in bright room environments. It can be viewed indoors with lights on and in natural light. However, it is not recommended for use outdoors in sunlight.

5.Q:Can the Mi Ambient Light Rejecting Projector Screen 100 be folded and curled?
A: As the Mi Ambient Light Rejecting Projector Screen is a hard screen, it cannot be curled or folded.

6.Q: How to care and maintain Mi Ambient Light Rejecting Projector Screen 100?
A: Don't touch the screen surface with your hands to avoid fingerprints or oil marks. If there is dust or stains, wipe the surface of the screen with a clean, soft, lint-free cloth with a small amount of neutral detergent.

7.Q: About the delivery and installation environment.
A: In order to ensure smooth delivery and normal installation, please confirm the delivery and installation environment before purchase.
