Pantalla LG 55UH5N-M Digital Signage plana 139,7 cm (55") LCD Wi-Fi 500 cd/m² 4K Ultra HD Negro WebOS 24/7

The LG 55UH5N-M is a 55-inch digital signage flat panel with an IPS LCD panel and 4K Ultra HD resolution (3840 x 2160). Designed for continuous 24/7 operation, the display delivers 500 cd/m² brightness, anti-glare coating for improved visibility in bright environments, built-in Wi‑Fi and the webOS platform with a high-performance SoC to run content without a separate media player. Its slim bezels, hidden power inlet and VESA compatibility make it suitable for space-efficient wall installations.

Advantages

The panel provides four times the detail of FHD for clear, legible images and reduces reflections with an anti-glare surface. A conformal coating on the power board and features such as IP5x protection and shock monitoring enhance durability in commercial environments by resisting salt, dust, iron powder and humidity. The outer cover is designed to limit flame spread, supporting use in public spaces. Integrated security technologies including LG Enhanced Kernel Protection (EKP) and ISO/IEC 15408 Common Criteria EAL2 certification protect data and system integrity. SuperSign content-management options and webOS app support simplify content deployment and integration with external sensors and partner solutions.

Configure sensors and partner apps through the webOS interface where integration is supported.

Recommendations

For reliable long-term operation, place the display in ventilated locations free from direct exposure to extreme moisture or corrosive particles. Use approved mounting hardware for public installations and ensure regular firmware updates to maintain security features such as EKP and Common Criteria compliance.
