3M, Liesegang Video Projectors
3M MP 8620   Liesegang ddv 810
For years, the company 3M cooperated with the German company Liesegang in the development of video projectors. During this time, Lengyel Design designed the Liesegang ddv 810 and 3M MP 8620 projectors, among other things.   The Liesegang projector is built in a horizontal format to improve the distance between stereo speakers and the asymmetrically arranged DLP image generation unit.

The 3M projector is equipped with a
collapsible housing in order to reduce
transport volume.
