The chip contains millions of micro-mirrors inside. While needed, the micro-mirror will rotate to positive and reflect the light through the lens to the screen. In this case, a bright pixel will be displaying. Opposite, the light will be reflected to the heatsink and displaying a dark pixel on the screen.
For this reason, one or more micro-mirrors are broken inside, the white spots are appearing like snow at night sky.
