## Long description

The SHARP/NEC Sharp LM431 is a 43" (109.2 cm) 4K Ultra HD digital signage flat panel with a touchscreen interface and integrated Android 14 SoC. Designed for small meeting spaces, huddle rooms and interactive signage, the display combines a high-brightness 3840 x 2160 LED panel with 500 cd/m² brightness, anti-glare coating and a slim four-sided bezel for flexible landscape, portrait or tilted-desk installations. Built-in Wi‑Fi, Ethernet and a native Android environment enable out-of-the-box collaboration and content delivery for continuous daily operation.
Advantages
The Sharp LM431 delivers clear readability in well-lit environments while its anti-glare surface reduces distracting reflections. Zero-bonded glass and infrared touch technology provide a Pen-on-Paper writing experience with responsive multi-touch (up to 20 points). An integrated Android 14 SoC and preinstalled apps support secure, seamless collaboration without additional hardware, and a single USB-C connection carries video, audio, data and power for simple BYOD workflows. Customisable settings, application lock and a built-in browser make the display suitable for cost-conscious interactive signage and wayfinding.
