LED failure cannot be found in the regular inspection test of LED industry Novastar MCTRL660. Under severe conditions such as high temperature, low temperature, and rapid temperature changes, it is caused by the difference in thermal expansion coefficients of LED chips, epoxy resin, brackets, inner leads, die-bonding adhesives, PPA cups and other materials, resulting in different internal stresses. The mechanism of LED failure caused by electrostatic discharge is very complicated. Equipment, tools, utensils, and human bodies may carry static electricity and discharge it. This static electricity ranges from several hundred volts to tens of thousands of volts. The discharge time is in the nanosecond range Level.
This design not only saves the
packaging cost, but also improves the reliability of the product. It has been
widely used in outdoor LED display products. The SAM (Scanning AcousTIc
Microscope) was used to test the airtightness of the LED bracket with the
folded structure design and the normal bracket. As a result, it can be found
that the product with the bent structure design has better airtightness. View More >> LED tools

The Novastar MCTRL660 Pro is mainly used for the rental and fixed fields, such as concerts, live events, security monitoring centers, Olympic Games and various sports centers. Multiple Novastar MCTRL660 Pro units can be cascaded. One-click backup and recovery, quickly recovering the previous screen configurations to deal with sudden on-site failure.
Briefly speaking, LED screen is made up of two parts: main display body which is composed by several display units Novastar MCTRLR5 (display panel units or display cabinet units) that can be connected together and a set of controller (main control board or control system). Multifarious display panels (or cabinet units) with different specifications and controllers with different control technology can be constituted into various kinds of LED screens to satisfy different application environments with diverse requirements.
