Abstract:
A scanning projector includes a programmable voltage source to provide a programmable voltage to a laser light source. A look-ahead circuit determines future voltage requirements by finding peaks in future pixel data. The programmable voltage may change for each frame of video, for each line of video, or multiple times within each line of video.
