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.
