APPARATUS AND METHOD FOR DETECTING ERROR AND VARIATION IN LIGHT-EMITTING DIODE LIGHTTING

摘要

Disclosed herein are an apparatus and method for sensing an error and a variation in Light-Emitting Diode (LED) lighting. In the method, a PWM signal including required light emission information is generated. Tail data including operation information is generated. A CRC value based on the tail data is also generated. A tail-CRC signal is generated by combining the tail data with the CRC value. Finally, a PWM-tail signal is generated by combining the tail-CRC signal with the PWM signal.
