Coated Backlit Textile LED Light Box 180gsm For Temporary Advertising Activities

The coarse-grained light box cloth (which may refer to the type with a rough surface texture) in the internal lighting light box cloth has specific application scenarios and performance characteristics in the advertising and display fields. The following is a comprehensive summary based on the search results:

Scope of application
1. Small and medium-sized indoor and outdoor light boxes
- The coarse-grained light box cloth usually has a high light transmittance (such as more than 20%), which is suitable for internal lighting design and is often used in indoor or semi-outdoor scenes, such as store door light boxes, exhibition exhibits, and advertisements in shopping malls.
- Some coarse-grained cloths may enhance the light scattering effect due to the surface texture, and are suitable for display environments that require soft light sources.

2. Special scene display
- The texture design may enhance the texture of the picture, which is suitable for scenes with high visual effects such as art exhibitions and brand image displays.
- Coarse-grained cloth with warp knitting technology (such as digital direct injection warp knitting cloth) can be used for high-end advertising light boxes that require high-definition pictures due to its compact surface and color expression.

3. Areas with lower wind pressure resistance requirements
- Unlike mesh cloth, coarse-grained cloth is generally not used for ultra-large outdoor typhoon-resistant scenes, but is more suitable for small and medium-sized billboards or indoor environments.

Features
1. Material and process characteristics
- Material: Usually based on polyester or PVC base fabrics, some products are coated (such as PVC coating) to enhance durability and flame retardancy, and some can meet the German B1 or French M1 flame retardant standards.
- Production process: It may adopt calendering or warp knitting process. The surface of calendering products is flat and the light transmittance is uniform, which is suitable for internal lighting; warp knitted fabrics have a tight structure, a light transmittance of ≥20%, and can block the shape of the light source.

2. Functional characteristics
- Ink absorption and color performance: Good ink absorption performance, combined with digital direct printing technology, can achieve colorful, high-saturation and environmentally friendly picture effects, which is better than traditional thermal transfer.
- Weather resistance: It has the characteristics of mildew resistance, UV resistance, cold and heat resistance, and is suitable for long-term outdoor use.
- Splicing and installation: Excellent splicing performance (such as higher strength after welding than the main body) and easy installation (post-folding and punching or direct pasting), adapting to different installation needs.

3. Surface characteristics
- Self-cleaning: Some products are treated with anti-fouling to reduce dust absorption and keep the screen clean.
- Texture design: The rough surface may enhance scratch resistance and improve the uniformity of the screen through light scattering, but it may reduce the transmittance.
