(one time only) 5. drive method an led is a current-operated device. in order to en sure intensity uniformity on multiple leds connecte d in parallel in an application, it is recommended th at a current limiting resistor be incorporated in t he drive circuit, in series with each led as shown in circui t a below. circuit model a circuit model b led led (a) recommended circuit. (b) the brightness of each led might appear differe nt due to the differences in the i-v characteristic s of those leds. 6. esd (electrostatic discharge) static electricity or power surge will damage the l ed. suggestions to prevent esd damage:
