100寸立式幕
A 100-inch freestanding projection screen is a display surface commonly used in home theaters, classrooms, conference rooms, and other settings where a large-format projected image is desired. The "100 inch" refers to the diagonal measurement of the viewable screen area. "立式" (Lìshì) indicates a freestanding design, meaning it has a base or support structure and doesn't require mounting to a wall or ceiling.
Material
The screen material is a critical component determining image quality. Common materials include:
- Matte White: The most common and affordable option. Offers a wide viewing angle and good color reproduction. Suitable for rooms with controlled lighting. May exhibit some glare in brighter environments.
- Glass Beaded: Contains microscopic glass beads to reflect more light, resulting in a brighter image. Good for rooms with some ambient light, but can have a narrower viewing angle and potential for hot-spotting (a brighter area in the center of the screen).
- Grey: Improves contrast ratio, especially in rooms with ambient light. The grey surface absorbs light, making blacks appear deeper. Requires a brighter projector.
- ALR (Ambient Light Rejecting): Designed to reject ambient light from above and sides, significantly improving image quality in brightly lit rooms. More expensive than other materials. Often has a specific gain and viewing angle.
- Acoustically Transparent: Allows sound to pass through the screen, enabling placement of speakers behind the screen for a more immersive audio experience.
The frame is typically constructed from aluminum alloy for lightweight strength and portability. The base is often made of metal or a weighted plastic for stability.
Purpose
The primary purpose is to provide a large, high-quality display surface for projected images from projectors. This is used for:
- Home Theater: Watching movies, TV shows, and playing video games.
- Classroom/Education: Presentations, lectures, and video playback.
- Conference Room/Business: Presentations, video conferencing, and data visualization.
- Gaming: Immersive gaming experiences with larger visuals.
Function
The screen functions by reflecting the light emitted from a projector, creating a visible image. Key functional aspects include:
- Image Reflection: The screen material efficiently reflects the projected light.
- Contrast Enhancement: Materials and coatings can improve the contrast ratio of the image.
- Viewing Angle: The screen material determines the optimal viewing angle for a clear image.
- Portability: Freestanding designs allow for easy movement and setup.
- Gain: Gain refers to the screen's ability to reflect light. Higher gain screens are brighter but have a narrower viewing angle.
Usage Scenarios
- Dedicated Home Theater Rooms: Where controlled lighting allows for optimal image quality.
- Living Rooms: For flexible entertainment options.
- Conference Rooms: For presentations and meetings.
- Classrooms: For educational purposes.
- Outdoor Events: Some screens are designed for outdoor use.
- Mobile Presentations: Portable screens are ideal for on-the-go presentations.
Common Types
- Manual Pull-Down: The screen is retracted and extended manually. Most affordable option.
- Electric/Motorized: The screen is retracted and extended using a motor. Offers convenience and remote control operation.
- Fixed Frame: The screen is permanently mounted on a frame. Provides a flat, wrinkle-free surface.
- Portable/Tripod: The screen is mounted on a tripod for easy transportation and setup.
- Floor Rising/Tab-Tensioned: The screen retracts into a base and rises up. Offers a clean look and often features tab-tensioning to maintain a flat surface.
- ALR (Ambient Light Rejecting) Screens: Available in both motorized and fixed frame options. Specifically designed for rooms with ambient light.
