description	A near-eye display for displaying an image to a viewer has enhanced laser efficiency and enhanced eye-safety features. The display includes a laser source which generates one or more laser spots and a scan driver which scans the laser spots across an image field. The electrical energy consumption is minimized by modulating the laser source at 3 power levels-a near-zero level, a near-threshold level, and a lasing level-and by synchronizing the modulation with the scan driver. In another embodiment, the laser module generates two or more laser spots which scan non-overlapping lines on the image field. The scanning is configured to prevent the light intensity at the eye of a viewer from exceeding eye-safety levels, even in the event of a scanning malfunction.
