LED DJ Display

LED DJ Booth is used different product models and structures as different conditions, which can be customized to the scene modeling. It can be spliced out the unique shape with different sizes of triangles, rectangles, hexagon. Unique DJ Table is not limited to kinds of environment. The application of the relevance and the shape of DJ LED Video Wall can enhance scene recognition.

LED Bar Display will not only present a delicate and realistic color performance through the synchronization adjustment, but also is compatible with different sources of input such as TVV, HDV, DVI, VGA, SDI. We adopt SMD technology to achieve super-wide viewing angle and better surface smoothness. Super light cabinet is to realize easy installation and maintenance that can be customized for shapes, sizes, pixels, resolution.
