(b) the brightness of each led might appear different due to the differences in the i - v characteristics of those leds. 7 . 6 esd (electrostatic discharge) static electricity or power surge will damage the led. suggestions to prevent esd dama ge: use of a conductive wrist band or anti - electrostatic glove when handling these leds. all devices, equipment, and machinery must be properly grounded. work tables, storage racks, etc. should be properly grounded. use ion blower to neutralize the static charge which might have built up on surface of the leds plastic lens as a result of friction between leds during storage and handling. esd - damaged leds will exhibit abnormal characteristics such as high reverse leakage current, low forward voltage, or no lightup at low currents. to verify for esd damage, check for lightup and vf of the suspect leds at low currents. the vf of good leds shoul d be >2.0v@0.1ma for ingan product led led
