"Deep Black" LED display is the industry's first sliding arc splicing screen with high-quality display and playback service. With "deep black" as the design concept, it features a new sliding arc lock design, two-step arc stitching, and a speed increase of 90%. This product allows you to replace the power box within 5 seconds to increase productivity by 80%, install protection devices on both sides of the cabinet to reduce the probability of lamp bead damage, or install two buffers on the top to protect the cabinet from damage. This solves problems such as cumbersome operation and easy damage to the lamp bead, and reduces customer transportation and installation costs.
