Patent ID: 8665188

Claim:
A circuit for providing a video image, comprising: a plurality of laser diode (LD) strings, wherein each LD string includes one or more LDs; a bias source that is arranged to provide a plurality of substantially static bias currents, wherein each bias current of the plurality of bias currents corresponds with, and is provided to, one LD string of the plurality of LD strings; a variable source that is capacitively coupled to each LD string of the plurality of LD strings and is arranged to capacitively couple a plurality of variable currents to the plurality of LD strings, wherein each variable current of the plurality of variable currents corresponds with, and is capacitively coupled to, one LD string of the plurality of LD strings, and wherein the output intensity of each LD of each LD string is based, at least in part, on the variable currents to each LD string; and a video processor that is arranged to provide a video signal to the variable source based, at least in part, on video data such that the plurality of variable currents is based, at least in part, on the video signal.
