In Laoshan, Qingdao, Shandong Province, a super-sized LED mega-screen in the command center is accurately displaying various types of public information and spatiotemporal data in split-screen format. This is the COB UHD display developed by Ledman for the operation center, with a main screen area of over 150 square meters and a resolution exceeding 20160*4320.
Ledman COB UHD display incorporates state-of-the-art full-flip-chip COB packaging technology to deliver clear, fine imagery while ensuring product stability and reliability, in addition to low maintenance costs in the long run. Full-flip-chip COB packaging technology is one of the leading techniques in the LED display industry, distinguished by its advantages in simplified manufacturing processes, streamlined structure, enhanced heat dissipation, high stability, and superior display performance.
Ledman COB UHD display is capable of aggregating and accessing billions of data entries and intelligent video signals, presenting them with high color fidelity and latency-free synchronization, outputting them point-to-point on-screen, thus achieving the vision of “observing the entire city on one screen, managing the whole city with one network, and benefiting the entire city from one interface.”
The project user praised, stating: “Ledman’s COB UHD display is a high-end LED display, boasting excellent image quality and high product stability.”
