Abstract
A driver and method for driving a semiconductor light emitting device array is provided. The driver includes at least one current regulator unit having a plurality of controllable switches to regulate the current of each set of cascaded light emitting devices in the semiconductor light emitting device array. The currents of the sets are used to generate a plurality of feedback signals through a feedback unit. A compensation unit generates a plurality of control signals in response to the feedback signals and a plurality of timing signals, so as to control the controllable switches. A driver according to the present invention can independently and individually control the luminance and timing of each set of cascaded light emitting devices.
