Lpdisplay's small pixel pitch LED displays have been implemented by the Huangzhou Water Conservancy Bureau to create a smart water management visualization system and an intelligent conference system, significantly enhancing their water management capabilities. This system enables real-time monitoring and early warning of water resource conditions, improving the management of water projects and effectively enhancing command capabilities for flood prevention and drought response. These small pixel pitch LED screens feature ultra-high resolution and seamless stitching, allowing for the display of high-definition dynamic water data, which strengthens the presentation and communication of water-related information. Additionally, these screens can be utilized as conference displays, supporting remote video conferencing to facilitate real-time communication across different regions, further boosting meeting efficiency.
