The heart of an effective light board design lies in the choice of materials. Typically, a high-quality acrylic sheet is used due to its excellent optical clarity and light transmission properties. Tempered glass is another alternative that offers scratch resistance and durability. The thickness of the board must strike a balance between rigidity and weight; usually, sheets ranging from 8mm to 12mm are optimal. The edges of the board are meticulously polished to allow for even LED diffusion, which ensures consistent brightness across the surface.
