Abstract
A circuit comprising an array of light emitting diodes (LEDs), and a layer of VSD material positioned to contact an input and an output of each LED in the array of LEDs, so as to protect each LED from both a forward surge and a reverse surge of voltage on the array of LEDs. The layer of VSD material is able to switch into a carrying current state in response to either of the forward or reverse surge exceeding a characteristic voltage level (VCL) of the VSD material.
