Corrosion Failure Analysis and Coping Strategies of Light Reflecting Devices in Light-Emitting Diode Devices

In the research, manufacturing and application process of light-emitting diodes, chemical corrosion is one of the most important causes of blackening of light-emitting diode (hereinafter referred to as LED) light-reflecting devices, which causes light decay and leads to product failure
