What if the mirrors stop? (Score 1)

Consider a display with typical XGA-range resolution. Since there is a single laser and roughly 1 million pixels, the scanning laser spends one millionth of its time on a single pixel, yet that pixel has to be bright enough to be visible. So what would happen if the mirror mechanisms failed while the laser was on? The laser would rest at a single spot on the retina with an apparent intensity about 1 million times that required to be a visible display. I would hazard to guess that that would indeed cause retinal damage.
