Detailed Comparison of Wall-Mounted Screen Parameters
Wall-mounted digital signage is a critical device in the commercial display sector, widely used in outdoor squares, electronic platforms, large supermarket chains, sports venues, airports, and other indoor and outdoor environments. Its design and technical features directly determine the product's performance and lifespan. Below is a detailed comparison of wall-mounted screen parameters, covering structural design, application benefits, performance stability, and installation convenience.
Structural Design
The structural design of wall-mounted screens is one of their core strengths. Featuring an ultra-thin design with a special surface coating, the device is not only aesthetically pleasing but also resistant to harsh environmental conditions. The combination of an aluminum alloy frame and a 4mm tempered glass panel ensures structural stability while providing explosion-proof and impact-resistant capabilities. The enclosure is made of 1.5mm galvanized steel plate coated with outdoor-specific powder, enhancing waterproof and anti-rust properties. The entire unit meets IP55 protection standards, effectively preventing dust and water ingress, making it suitable for various challenging environments. Additionally, the modular design facilitates easy maintenance of internal components such as the display panel, glass, cooling system, and electronic parts. The top-mounted lifting points further simplify transportation and installation.
Application Benefits

Wall-mounted screens offer exceptional flexibility in application. Compatible with both X86 platforms and Android systems, users can choose different configurations to meet diverse functional requirements. Whether for advertising, information display, or interactive applications, the device delivers rapid responsiveness. It supports plug-and-play deployment, enabling immediate use upon arrival at the designated location, significantly reducing setup time. Moreover, customers can customize appearance designs and functional configurations based on specific needs, such as adjusting screen brightness, resolution, or adding specialized interface modules to cater to unique scenarios.

Performance stability is key to the long-term reliability of wall-mounted screens. Equipped with industrial-grade control boards and power supplies, the device operates stably even in extreme temperatures or high humidity. The high-brightness display (2000cd/m²) ensures clear visibility under direct sunlight, while the 178-degree wide viewing angle guarantees optimal visuals from any perspective. An built-in ambient light sensor automatically adjusts screen brightness based on environmental conditions, optimizing display quality and energy efficiency. The cooling system employs a professional air duct design, efficiently dissipating heat through dual air channels. Intelligent temperature control adjusts fan speed according to internal temperatures, balancing cooling performance with reduced energy consumption and noise levels.

The technical specifications of wall-mounted screens cover display, electronics, cooling, and protection features. The display utilizes DLED backlight technology with a resolution of 3840×2160, pixel pitch of 0.630×0.630mm, contrast ratio of 3000:1, response time of 6ms, and support for 8bit color depth (16.7M colors). The electronic components include an RK3288 quad-core processor (1.8GHz), 2GB RAM, and 16GB ROM, supporting multiple video, audio, and image formats. For connectivity, the device offers RJ45 Ethernet, WiFi 802.11b/g/n, Bluetooth 4.0, and ports such as HDMI, USB, TF card slot, and SIM card slot. Protection features include leakage prevention, lightning protection, dust resistance, and explosion-proof capabilities, with an operating temperature range of -20℃ to 50℃ and humidity tolerance of 10% to 90% (non-condensing).
