2. Digital Displays: With advancements in digital technology, businesses now use digital displays and screens for dynamic and interactive signage. These displays can show animations, videos, and changing content, providing a modern and engaging way to attract attention.

4. Fluorescent Tubes: While not as popular as they once were, fluorescent tubes are still used for certain types of signage. They are known for their efficiency and brightness.

5. Fiber Optic Signs: Fiber optic technology allows light to be transmitted through thin, flexible strands of glass or plastic. Fiber optic signs can create unique lighting effects and are sometimes used for decorative purposes.

6. Projection Mapping: This involves projecting images or videos onto surfaces to create dynamic and interactive displays. While not a direct replacement for traditional signs, projection mapping is used in creative ways for advertising and branding.
