Driven by the dual drive of the national dual-carbon goal and the intelligent construction policy of coal mines, the coal industry is accelerating its bid farewell to the traditional production model and deeply transforming into intelligence, green and digital directions. As a leader in the field of Micro LED ultra-high definition display,
Lehman Optoelectronics has successfully cooperated with China Coal, Shaanxi Coal, Lu 'an, Gansu Huating and other large coal companies relying on its independently developed advanced
COB packaging technology and accumulated experience in benchmarking projects in multiple industries. Coal companies have reached in-depth cooperation to create a series of smart coal mine display solutions, injecting key technical strength into safe production, efficient scheduling and green operations of coal mines.
Lehman" Optoelectronics customizes the output of COB ultra-high-definition display products based on the operating needs of different coal mines, from the dispatch center to the production site, realizing a unified view of the entire area on one screen and a smart upgrade of data-driven decision-making".
雷曼光电针对不同煤矿的运营需求，定制化输出 COB 超高清显示产品，从调度中心到生产现场，实现 "一屏统览全域、数据驱动决策" 的智慧升级。

在中煤集团某能源公司的煤炭生产调度中心，雷曼 COB 超高清大屏（分辨率达 9120*2160）成为核心视觉载体。The large screen can simultaneously present underground production data, equipment operating status and multi-point monitoring pictures in real time, integrating originally scattered information into a dynamic data map. By building an intelligent scheduling system with rapid response, accurate decision-making, and controllable risks, dispatchers can intuitively grasp the entire production process, and command efficiency and safety management level have been significantly improved. Scheduling instructions that used to require multi-link communication can now be transmitted through large-screen data Linkage achieves second-level issuance.

陕煤张家峁煤矿的智慧调度中心，搭载了雷曼一块 "巨无霸" 级 Micro LED 超高清显示大屏 —— 宽 18 米、高 7 米，分辨率高达 19200× 7560 像素，相当于 20 余块 4K 屏幕的拼接效果。The large screen deeply integrates the 5G network and the cloud data platform to integrate and optimize data from 92 independent systems (covering underground mining, ventilation, transportation, power supply, etc.) throughout the mine, realizing real-time sharing of multi-screen information. For example, equipment failure signals in underground driving faces can be instantly pop-up on the large screen, and at the same time, they can be linked with the scheduling information of the ground maintenance team, allowing the entire mine operation to shift from decentralized management to integrated collaboration, greatly improving transparency and safety.
