Display boards are flat surfaces used to present information visually. They are commonly made from materials like cardboard, foam board, or wood and can be found in various sizes. Display boards are often used in schools for projects, in businesses for presentations, and at events for showcasing products or information. These boards can be decorated with text, images, and graphs to effectively communicate ideas. They are versatile tools for education, marketing, and public information, making it easier for audiences to understand complex topics. Display boards are also used in competitions, such as science fairs, to highlight research findings and creative projects.
