Multi-color light emitting device circuit
The present invention discloses a multi-color light emitting device circuit, which includes: multiple light emitting device strings of different colors, a timing control circuit, a power regulator circuit, and preferably a dark feedback circuit. Each light emitting device string has multiple light emitting devices coupled in series. The number of the light emitting devices of each light emitting device string is determined by an operational voltage of the light emitting device, wherein at least two of the light emitting device strings have different numbers of the light emitting devices, such that voltage drops of the two light emitting device strings are closer to each other than in a case wherein the two light emitting device strings have the same number of the light emitting devices, and the response time of the light emitting device strings are increased.
