signboards

Signboards are panels or boards used to convey information, directions, or advertisements to people outside a building or space. They are typically mounted on façades, posts, or freestanding frames, and they vary in size, material, and illumination to suit local context and purpose.

Early signboards emerged in ancient and medieval cities, where artisans and shopkeepers displayed painted or carved signs to indicate trades to a largely illiterate public. The development of street signage and illuminated signs began in the 19th and 20th centuries, expanding to digital displays in recent decades.

Common types include informational and directional signs that aid navigation, advertising and retail signboards that promote products or brands, shopfront and street-name signs that identify locations, and safety or warning boards used in workplaces or public spaces. Digital and illuminated boards display scrolling text, images, or animations for enhanced visibility.

Effective signboard design emphasizes legibility and clarity. Key elements include concise wording, simple symbols, high contrast typography, and appropriate sizing for viewing distance. Materials range from wood and metal to plastics such as aluminum or acrylic. Signboards may be static or illuminated by neon, LEDs, or backlighting, with considerations for weather, wind loads, and energy use.

Signboards are commonly subject to local planning, zoning, and safety regulations. Permits may be required; spacing, height, lighting, and durability standards are enforced to reduce hazards and visual clutter. Regular maintenance involves cleaning, repainting, and servicing illumination and hardware.
