Studies of the failure mechanisms in LED and its driving module

The increasing demand for light emitting diodes (LEDs) has been driven by a number of application categories. The construction of LEDs is somewhat similar to microelectronics, but there are functional requirements, materials, and interfaces in LEDs that make their failure modes and mechanisms unique. In this paper, the main failure modes and mechanisms of LED device and its driving module are investigated through some latest literature, and some improving methods to improve the LED's reliability are put forward.
