Led pixel light electrostatic discharge sensitivity.
The LED quality testing is a very complex task. Furthermore, electrostatic discharge, for GaN-based LED is the greatest incentive for its failure. Electrostatic Discharge LED failure mechanism is very complex, equipment, tools, utensils and the human body may have with static electricity and its discharge, this electrostatic least a few hundred volts, the high tens of thousands of volts, discharge time in the nanosecond level . Blue-green screen production, installation, use the process tube failure is often the LED-PN junction electrostatic discharge breakdown actions. The International the electrostatic Association strictly the provisions of the standard electrostatic discharge mode, and is divided into the Human Body Model (HBM) and machine discharge mode (MM). Our device electrostatic discharge sensitivity (ESDS) is divided into three levels (human body model): 1 to 0 to 1999V; 2 level 2000 ~ 3999V; 3 levels above 4000V.
