I have a light engine assembly from a Samsung DLP rear projector left over from a repair. It's the assembly that the MMD bolts to. It has a light pipe, which I understand, a hole for the MMD which, tho it amazes me, I understand, two lenses, and a mirror, all of which I understand.
But what I don't get is this electronic gadget attached to the back of the mirror. At first I thought it was a temperature sensor, but recently when I got a chance to inspect it more closely I see that it is marked "VCM driver - Hysonic," search terms which dig up all kinds of interesting things. What function does this thing serve in a TV? Is this some kind of anti-aliasing technology like the lens vibrator in a digital camera? Just curious.
