Ambient light rejecting (ALR) technology is designed to enhance the viewing experience in environments with significant natural or artificial light. It works by filtering out unwanted light while allowing the projector's image to be clearly visible. This is particularly useful in settings like living rooms or conference rooms where controlling light levels can be challenging. ALR screens are often used with projectors to improve image quality and contrast. By minimizing the impact of surrounding light, these screens help maintain vibrant colors and sharp details, making them ideal for both home entertainment and professional presentations.
