| Transparency | Approximately 50%–90%, depending on LED spacing, cabinet structure, and louver design. | 60%–80% transparency for storefronts and glass façades. | Higher transparency preserves daylight, exterior views, and the architectural appearance of the building. | Request a front-and-back visibility test using the actual content brightness and cabinet configuration. |
| Pixel Pitch | Common options range from about 3.9 mm to 15.6 mm. | 3.9–6.25 mm for close viewing; 8–10 mm for medium and long viewing distances. | A smaller pixel pitch produces finer image detail but generally increases cost, power consumption, and LED density. | Match the pixel pitch to the nearest viewer distance, screen size, and content type. |
| Recommended Viewing Distance | Approximately 4–20 m, depending on pixel pitch, image content, and viewing conditions. | Use a smaller pitch for indoor audiences and a larger pitch for distant façade advertising. | The correct viewing distance prevents visible pixel structure while avoiding unnecessary specification and cost. | Inspect moving video, text, and high-contrast images from the closest expected viewing position. |
| Brightness | Indoor models commonly provide about 800–1,500 nits; outdoor models commonly provide about 4,500–6,000 nits. | 1,000–1,500 nits indoors and at least 5,000 nits for direct-sunlight applications. | Brightness must overcome ambient light while avoiding glare, excessive power use, and reduced transparency. | Confirm brightness at calibrated settings, not only the maximum peak value. |
| Refresh Rate | Typically 1,920–3,840 Hz, with higher rates available for professional production. | At least 3,840 Hz where cameras, live events, or broadcast recording are involved. | A higher refresh rate helps reduce flicker, scan lines, and rolling-bar effects on camera. | Test the display with the cameras and shutter speeds that will be used at the venue. |
| Color Performance | Usually supports 8-bit or higher grayscale processing per color channel, with wide-angle viewing. | High grayscale performance and automatic brightness calibration for consistent imagery. | Good grayscale and color uniformity improve skin tones, gradients, shadows, and branded visual content. | Check grayscale images, dark scenes, white balance, and color consistency across several cabinets. |
| Viewing Angle | Often approximately 120°–160° horizontally and vertically, depending on LED and louver design. | At least 140° horizontal viewing angle for public-facing installations. | A wide viewing angle keeps images readable for people approaching from different directions. | Evaluate brightness, contrast, and color shift from side angles rather than checking only the front view. |
| Cabinet Weight | Many lightweight transparent systems weigh approximately 10–20 kg/m², excluding some structural supports. | Choose the lightest system that meets wind-load, rigidity, and service requirements. | Lower weight can reduce structural loading and simplify installation on glass façades or suspended frames. | Confirm the complete installed weight, including cabinets, power supplies, cables, mounting rails, and brackets. |
| Wind Resistance | Performance depends on cabinet openness, support structure, installation height, and local wind conditions. | Use an engineered structure with a documented wind-load calculation for outdoor façades. | The open design reduces wind pressure compared with solid LED walls, but it does not eliminate structural risk. | Obtain structural calculations and verify compliance with the local building and safety requirements. |
| Ingress Protection | Indoor products may have limited protection; outdoor products commonly target IP65 on the exposed side. | IP65 or higher for exposed outdoor surfaces, with protected power and signal connections. | Ingress protection helps protect the LEDs and electronics from rain, dust, and other environmental exposure. | Check whether the stated rating applies to the complete assembled display or only selected components. |
| Operating Temperature | Typical commercial specifications are approximately −20°C to 50°C, subject to the selected components. | Select a temperature range suitable for the local climate, with thermal management where necessary. | Temperature affects LED lifetime, brightness stability, power supply reliability, and maintenance frequency. | Review the tested operating range and confirm ventilation, heat dissipation, and condensation control. |
| Power Consumption | Typical maximum consumption is often about 400–800 W/m²; average consumption is usually lower. | Specify automatic brightness control and request both maximum and average power figures. | Power consumption affects operating cost, electrical capacity, heat generation, and environmental performance. | Calculate total power using the actual screen area, brightness setting, content pattern, and local electricity rate. |
| Serviceability | Front-service, rear-service, or modular service designs are available. | Use front service where the screen is mounted directly against glass or a restricted structure. | Easy access reduces downtime and avoids dismantling façade elements during repairs. | Confirm replacement procedures for LED modules, receiving cards, power supplies, and data cables. |
| Control and Connectivity | Common systems support Ethernet, video processors, asynchronous players, and scheduled content playback. | Choose a control system with remote monitoring, brightness scheduling, and fault alerts. | Reliable control simplifies content updates, troubleshooting, and energy management across multiple displays. | Verify supported input resolutions, maximum cabinet count, network security, and offline playback capability. |
| Expected LED Lifetime | LED packages are often rated for up to approximately 100,000 hours under specified conditions. | Treat lifetime as a component rating and prioritize thermal design, drive current, and warranty terms. | Real service life depends on brightness, operating temperature, humidity, power quality, and maintenance. | Ask for the rated conditions, module warranty, brightness-retention criteria, and spare-parts policy. |
| Best Application Fit | Suitable for retail windows, commercial façades, atriums, stage backdrops, exhibitions, and architectural media. | Select the display based on transparency, viewing distance, ambient light, weather exposure, and access constraints. | No single specification is best for every project; application conditions determine the correct balance of image quality, openness, durability, and cost. | Use a sample cabinet or full-size mock-up whenever the display will be integrated into an existing glass or architectural structure. |
