A display board is a flat, rectangular surface used to showcase information, images, or objects in a visually appealing and organized manner. It is typically made of sturdy material, such as cork, foam, or fabric, and can be mounted on a wall or placed on a stand. Display boards are commonly used in schools, offices, and events to present projects, announcements, or advertisements. They serve as a creative and effective way to capture attention and convey important messages to an audience.
