LED GOB (เคลือบกาว)

GOB and SMD are two LED display technologies with distinct advantages: **GOB (Glue on Board):** - Protective glue coating over LED chips - IP65 waterproof, dustproof, impact-resistant - Best for: outdoor advertising, building facades, high-traffic areas - Price: from 22,000 THB/sqm ($620 USD) **SMD (Surface-Mount Device):** - LED chips mounted directly on PCB - Higher resolution, wider viewing angle (160°+) - Best for: indoor displays, close-viewing distance, retail - Price: from 19,500 THB/sqm ($550 USD) Choose GOB for outdoor durability. Choose SMD for image quality.

LED display prices per square meter vary by technology and pixel pitch: **Indoor LED (SMD):** - P2.5 (high resolution): from 19,500 THB/sqm ($550 USD) - P3 (standard): from 16,000 THB/sqm ($450 USD) - P4 (economy): from 13,000 THB/sqm ($370 USD) **Outdoor LED (GOB):** - P3 (high resolution): from 25,000 THB/sqm ($710 USD) - P4 (standard): from 22,000 THB/sqm ($620 USD) - P6 (large format): from 18,000 THB/sqm ($510 USD) **Additional costs:** Installation (2,000-5,000 THB/sqm), control system (15,000-30,000 THB), structural support (varies). Volume discounts available for orders over 10 sqm.

Calculate LED display size based on three factors: **1. Viewing distance** — Minimum viewing distance (in meters) ÷ pixel pitch = recommended pixel pitch. - 2-4m viewing: P2.5 or P3 - 4-8m viewing: P3 or P4 - 8-15m viewing: P4 or P6 **2. Wall/facade dimensions** — Measure the available installation area. Common sizes: - Small: 2m × 1m (2 sqm) - Medium: 4m × 2m (8 sqm) - Large: 6m × 3m (18 sqm) **3. Content resolution** — For video content, minimum 1920×1080 pixels total. **Formula:** Width (m) × Height (m) = Total sqm × Price/sqm = Total cost. Example: 4m × 2m outdoor GOB P4 = 8 sqm × 22,000 THB = 176,000 THB.
