How Digital Light Processing (DLP) works


Ben Krasnow, from Applied Science, explains how a projector works. He is one of the most skilled guys I’ve seen on Youtube. If he does not have a tool or device, he builds it and then moves on.

Digital Light Processing (DLP) works by using a ton of microlenses that reflects the light corresponding to one pixel to a screen. As opposed to LCD projectors, Digital Light Processing has smaller energy consumption and a better image quality.

The fact that you can use microlenses, lenses that are only 10 micrometers in length, and that you can move them is an incredible feat. In the video from above you will see how such microlenses are looking when using a scanning electron microscope. Awesome!
