| LED Package Type | Through-hole red, green, and blue LED lamps installed directly on the module | DIP stands for Direct In-line Package. Individual LED lamps are physically separated and generally have strong mechanical protection. | Choose DIP when outdoor visibility, impact resistance, and long viewing distances are more important than ultra-fine pixel density. |
| Common Pixel Pitch | Approximately 8–20 mm | Pixel pitch is the center-to-center distance between two adjacent pixels. A larger pitch normally suits longer viewing distances. | Use the smallest pitch that fits the viewing distance and budget. Avoid selecting a very fine pitch if viewers will remain far away. |
| Recommended Viewing Distance | About 8–20 m, depending on pixel pitch | At the correct distance, pixels blend into a clearer image and text appears less granular. | For roadside or stadium applications, calculate the minimum viewing distance before choosing the pitch. |
| Typical Brightness | Approximately 6,000–10,000 nits | Brightness is measured in nits, or candelas per square metre. High brightness helps content remain visible in direct sunlight. | Use automatic brightness control to reduce glare, power consumption, and unnecessary LED stress at night. |
| Outdoor Protection Rating | Commonly IP65 for the front and IP54–IP65 for the rear | The first IP digit indicates protection from solids and dust; the second indicates protection from water. | For exposed installations, verify the complete assembled cabinet rating rather than relying only on the module rating. |
| Operating Temperature | Typically −20°C to +60°C | The operating range indicates the environmental temperatures in which the display is designed to function. | Check the local climate, solar heat gain, ventilation, and whether additional heating or cooling is required. |
| Viewing Angle | Approximately 100°–140° horizontal; 40°–80° vertical | Viewing angle describes how far viewers can move away from the display centerline before brightness or color changes noticeably. | Use a wider angle for roadside, retail, and public-space displays viewed from multiple directions. |
| Refresh Rate | Commonly 1,920–3,840 Hz | A higher refresh rate reduces visible flicker and improves camera-recorded images. | For sports venues, broadcasts, live events, or displays frequently filmed by smartphones, select a higher refresh rate. |
| Color Processing | Usually 16-bit or higher grayscale processing per color channel | Higher grayscale capability supports smoother gradients and more natural transitions in bright and dark areas. | Confirm the complete system specification, including the controller and receiving cards, rather than the LED module alone. |
| Cabinet Structure | Steel or aluminum cabinets with sealed modules, power supplies, and receiving electronics | The cabinet protects internal components from weather, dust, vibration, and installation stress. | Choose corrosion-resistant materials and provide drainage, service access, and secure mechanical mounting. |
| Power Supply | Commonly 5 V DC LED modules with AC input power supplies | LED pixels operate at low DC voltage, while the display receives mains electricity through regulated power supplies. | Verify input voltage, grounding, surge protection, power redundancy, and compliance with local electrical regulations. |
| Average Power Consumption | Approximately 250–500 W/m² during typical content | Average consumption is lower than maximum consumption because real content rarely drives every pixel at full white continuously. | Size the electrical system using maximum rated consumption, then estimate operating cost using realistic content and brightness settings. |
| Maximum Power Consumption | Approximately 700–1,200 W/m² at full white | Maximum consumption represents a high-load condition in which red, green, and blue channels operate at high output. | Use this value for circuit capacity, cable sizing, breakers, thermal management, and backup-power calculations. |
| Expected Service Life | Approximately 80,000–100,000 operating hours to 50% initial brightness | LED lifetime is commonly specified as the time until light output falls to about half of the initial level, not as a guarantee of failure-free operation. | Prioritize thermal design, stable current control, weather sealing, and maintenance quality to support long service life. |
| Maintenance Access | Front maintenance, rear maintenance, or a combination of both | Maintenance access determines how easily modules, power supplies, and control components can be replaced. | Use front access where the rear of the display is obstructed; provide rear access where frequent servicing and ventilation are priorities. |
| Best-Fit Applications | Roadside advertising, stadiums, transportation areas, building façades, outdoor events, and large-format information boards | These applications typically require high brightness, weather resistance, long viewing distance, and robust construction. | A high-brightness, weather-sealed DIP display is generally appropriate for harsh outdoor environments and long-distance viewing. |
| Main Advantages | High daylight brightness, durable lamp construction, strong outdoor visibility, and good impact tolerance | DIP lamps are often selected for demanding outdoor conditions where robustness is a major concern. | Consider DIP technology when reliability in sunlight and severe weather is more important than a very small pixel pitch. |
| Main Limitations | Typically larger pixel pitch, lower close-up image smoothness, larger physical lamp profile, and potentially higher power use | The separated lamp structure can limit fine-pitch performance compared with many surface-mounted designs. | For close viewing distances, detailed graphics, or indoor applications, evaluate a finer-pitch alternative before making a final decision. |
| Key 2026 Buying Criteria | Pixel pitch, calibrated brightness, IP rating, refresh rate, energy use, heat management, service access, and structural safety | A high-quality display must balance visual performance, environmental protection, operating cost, and maintenance requirements. | The best outdoor DIP LED display is the one whose specifications match the site conditions, viewing distance, content type, and total cost of ownership. |
